Password (密码) strength has been a topic about the Internet lately. I have seen lots of clever methods for generating and remembering strong passwords. Some are better than others, but in my opinion, none are adequate. Here's the problem: It doesn't matter how strong your passwords are if you use the same one on multiple sites. All it takes is for a site to get hacked(侵入), like Gawker media, or even Sony did, and now your superstrong password has been stolen, and every site on which you used that password has been accessed.
So, the bottom line is that no matter how strong your passwords are, and no matter what clever tricks you use to help you remember them, if you surf internet often, the only truly secure password system is what you need.
Enter LastPass. It's not the only password manager out there, but I like it the best. You create ONE strong password that you have to memorize and use it to access your LastPass database. The LastPass database is stored online, on LastPass's servers. LastPass recognizes the site you're on and automatically logs you in (after, optionally, asking you to reenter your master password). LastPass also has automatic form fill and automatic password generation. This means that you can have a different, unique, very strong password for every site you log into, but you only have to remember one master password. It's the best of both worlds.
One argument against LastPass is that if their database is attacked, then all of your sites are in danger, and that's true, but given that their entire line of work is keeping that information safe, I'm willing to take that chance. The alternative is rolling dice(掷骰子) or picking phrases to create passwords, writing all of them down on a piece of paper or something, and then having to manually type them in when I go to a site. A terrible mess.
There is a free version of LastPass, with some additional features unlocked if you pay a $12 a year subscription.

Last night’s meteor(流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothsclild, Emerald Valley’s mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead.
“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments.”
Astronomers---scientists who study stars and planets----have been complaining about this problem for decades.They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.
There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds,bats frogs,snakes,etc. For example,outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100 million birds a year throughout North America die in crashes with lighted buildings and towers.”
Countless more animals casualties(伤亡）result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings,but some scientists think it can be harmful for humans,too. They worry that exposure to light while sleeping can increase person’s chances of getting cancer.
Emerald Valley is only one community that is becoming aware of the negative effects of hight pollution. For years, Flagstaff,Arizona, has enforced lighting regulations in its city in order to help astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.
【小题1】It happened last night that __________ .
| A．the city light show attracted many people |
| B．the meteors flew past before being noticed |
| C．the city’s lights affected the meteor watching |
| D．the meteor watching ended up a social outing |
| A．Light pollution has remained unsolved for years |
| B．Their observation equipment is in poor repair |
| C．Meteor showers occur less often than before |
| D．Their eyesight is failing due to artificial lighting |
| A．Birds may take other migration paths |
| B．Animal’living habits may change suddenly |
| C．Varieties of animals will become sharply reduced |
| D．Animals’survival is threatened by outdoor lighting |
| A．Lessen the chance of getting cancer |
| B．ensure citizens a good sleep at night |
| C．create an ideal observation condition |
| D．enable all creatures to live in harmony |
| A．Saving wildlife is saving ourselves |
| B．Human activities should be environmentally friendly |
| C．Great efforts should be made to save energy |
| D．New equipment should be introduced for space study |

It’s generally believed that people act the way they do because of their personalities and attitudes. They recycle their garbage because they care about the environment. They pay $5 for a caramel brulee latte because they like expensive coffee drinks.
It’s undeniable that behavior comes from our inner dispositions（性情）, but in many instances we also draw inferences about who we are, as suggested by the social psychologist Daryl Bern, by observing our own behavior. We can be strangers to ourselves. If we knew our own minds, why should we need to guess what our preferences are from our behavior? If our minds were an open book, we would know exactly how much we care about the environment or like lattes. Actually, we often need to look to our behavior to figure out who we are.
Moreover, we don’t just use our behavior to learn about our particular types of character --- we infer characters that weren’t there before. Our behavior is often shaped by little pressures around us, which we fail to recognize. Maybe we recycle because our wives and neighbors would disapprove if we didn’t. Maybe we buy lattes in order to impress the people around us. We should not mistakenly believe that we always behave as a result of some inner disposition.
Whatever pressures there can be or inferences one can make, people become what they do, though it may not be in compliance（符合）with their true desires. Therefore, we should all bear in mind Kurt Vonnegut’s advice: “We are what we pretend to be, so we must be careful about what we pretend to be.”
【小题1】According to the passage, personalities and attitudes are commonly believed to _______.
| A．determine one’s behavior | B．reflect one’s taste |
| C．influence one’s surroundings | D．result from one’s habits |
| A．The return of a wallet can indicate one’s honesty. |
| B．A kind person will offer his seat to the old. |
| C．One recycles plastics to protect the environment. |
| D．One buys latte out of love of coffee. |
| A．We fail to realize our inner dispositions. |
| B．We can be influenced by outside pressures. |
| C．Our behavior is the result of our true desires. |
| D．Our characters can shape our social relationships. |
| A．Personalities and attitudes. | B．Preferences and habits. |
| C．Behavior and personalities. | D．Attitudes and preferences. |

The sound of a mosquito can mean trouble in many parts of the world. The bite of the mosquito can be deadly. The insects carry serious diseases like malaria. It is estimated that almost 630,000 people died from malaria and malaria-related causes in 2012, and most of these cases were in African countries.
In the United States, a group of California scientists is working to develop a more effective and less costly substance(物质)to protect people from mosquitoes. The researchers are investigating the sense of smell in mosquitoes. They found the insects use the same receptor(感受器)for identifying carbon dioxide in human breath as they do for the smell of our skin. Anandasankar Ray, who is leading the investigation, says scientists tested more than a million chemical compounds(化合物)until they found a substance called Ethyl pyruvate. He says Ethyl pyruvate makes the mosquitoes' receptor inactive. ”When we apply Ethyl pyruvate to a human arm and offer it to hungry mosquitoes in a cage, very few of the mosquitoes are attracted to the human arm because only a few of them are able to smell it out,” said Ray.
Genevieve Tauxe, a member of the research team, says it was not easy to find the neurons (神经元)of nose cells that recognise both the smell of human breath and skin. "With the device used to examine mosquitoes, we are able to insert a very small electrode(电极)into the part of the mosquitoes' nose, where its smelling neurons are and where the smell is happening," said Tauxe.
Anandasankar Ray says a product based on Ethyl pyruvate may cost less to produce than DEFT，the most effective chemical treatment now in use. He says DEFT is too costly for most people who live in areas affected by malaria.
“Perhaps by finding smells that can attack other target receptors, we will be able to improve upon DEFT and finally have the next generation of insect behavior control products," said Ray.
【小题1】The best title for the passage is most probably _______________________________.
| A．Scientists Find New Substance to Fight Mosquitoes |
| B．A New Generation of DEET Has Been Developed to Kill Mosquitoes |
| C．Malaria一a Serious Disease Causing 630,000 Deaths |
| D．Ethyl Pyruvate一an Insect Behavior Control Product |

| B．cause the mosquitoes to lose their sense of smell |
| C．result in the inactiveness of the mosquitoes' receptor |
| D．make the mosquitoes uninterested in human breath and skin smell |
| A．inform readers of the new development in fighting mosquitoes |
| B．praise the achievements made in the battle against malaria |
| C．introduce a cheaper product in fighting mosquitoes |
| D．tell the differences between Ethyl Pyruvate and DEET |
| A．the column of newspaper ads |

An alcohol breath test (ABT) is often used by the police to find out whether a person is drunk while driving.In the United States，the legal blood alcohol limit is 0.08% for people aged 21 years or older，while people under 21 are not allowed to drive a car with any level of alcohol in their body.A “positive” test result，a result over the legal limit，allows the police to arrest the driver.However，many people who tested positive on the test have claimed that they only drank a “nonalcoholic” energy drink.Can one of these energy drinks really cause someone to test positive on an ABT？Researchers in Missouri set up an experiment to find out.
First，the amount of alcohol in 27 different popular energy drinks was measured.All but one had an alcohol level greater than 0.005%.In nine of the 27 drinks，the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT.They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.
For 11 of the 27 energy drinks，the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken.However，alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed.This shows that when the test is taken plays an important role in the test result.The sooner the test is conducted after the consumption of these drinks，the more likely a positive alcohol reading will be obtained.

For many of us, a little time with our smartphones or iPads before sleep is the highlight of the night. But would you still think it is relaxing if you knew that it damages or destroys your sleep? Scientists say that's exactly what it does.
In ancient times, when there were no lamps, telephones or smartphones, the sun was the main source of light. When the sun went down, our brains took that as a signal to start producing melatonin(褪黑素), a chemical that helps us sleep.
However, a healthy amount of melatonin can only be produced in complete darkness.Any light in your bedroom—even the one on the alarm clock or the charging indicator on your cellphone—could disturb the process, not to mention something as bright as smartphone and iPad screens. We tend to hold these much closer than a television or laptop, which allows them to shoot far more light straight into our eyes.
“This is particularly worrisome in populations such as young adults and adolescents, who already tend to be night_owls，” said researcher Brittany Wood at Rensselaer Polytechnic Institute.“Lack of sleep among teens is leading to depression, selfharm, low concentration and poor performance at school，” she added.
While all lights are the enemy of sleep, not all colors of light have the same effect. Our eyes are particularly sensitive to blue light, which is common during the day. Most of the light coming from electronic screens is blue light and it fools our brain into thinking it's still daytime. By contrast, orange or red light has less influence on melatonin production, because our brains recognize it as a signal that the day is ending, according to The Telegraph.
Asking yourself to keep your hands off your smartphone before bedtime might seem unreasonable, but you should at least remember to dim the screen or hold it farther away from your eyes. You could also wear a pair of orange sunglasses that take away the harmful blue light.
【小题1】According to the passage, we can know ________.
| A．it's a good habit to play with smartphones or iPads late into night |
| B．scientists suggest we should avoid using smartphones or iPads |
| C．darkness makes a great impact on the amount of melatonin |
| D．the sun was the only source of light in ancient times |
| A．The darker it is, the more melatonin will be produced. |
| B．The lighter it is, the more melatonin will be produced. |
| C．The more melatonin you have, the worse you'll sleep. |
| D．The more electrical equipment you have, the more melatonin will be produced. |
| A．who are young adults or adolescents |
| B．who don't perform well in school |
| C．who are addicted to a television or laptop |
| D．who are short of sleep at night and perform poorly in daily life |
| A．You should go to bed when the sun goes down. |
| B．You should use an orange or red light electronic screen. |
| C．You should wear a pair of blue sunglasses when sleeping. |
| D．You should avoid blue light as possible as you can before bedtime. |

As we enjoy the summer ocean waves along the beaches, we may think nervously about Steven Spielberg's Jaws and the great fear that sharks inspire in us. Yet we are happy to see global efforts to protect the declining number of sharks. The world has realized that we need the species, like sharks, to keep a balanced ecosystem.
Sharks, in particular, are “in” these days. Thanks to good public policy and famous stars such as Jackie Chan and Ang Lee, killing sharks for fin soup is no longer cool.
The demand for shark fins has been rising for decades, threatening sharks with extinction(灭绝)—up to 100 million sharks are killed each year just for their fins. But we have started to reverse the trend, particularly in many areas of the United States and overseas where restaurants once proudly provided delicious shark fins on the menu.
In California, a ban on the sale and possession of shark fin soup has gone into effect this year through the efforts of Wild Aid and other organizations.
Overseas marketing and public efforts featuring posters on public transportation systems and TV ads have been underway for the past few years. These efforts all show signs of success, on both the supply side and the demand side of trade in shark fins.
Actually, stopping the killing of sharks is part of a broader movement to stop the killing of wild animals and the buying and selling of wildlife products. These products come from hunting elephants, tigers and rhinos, besides killing marine life.
Whether it is shark fin soup or ivory piano keys, killing animals is big business. The hunting of elephants in search of ivory tusks for luxury(奢侈的)goods has become a fullscale war. The decrease of African elephant populations is alarming. Together with international partners, the United States is leading the worldwide effort to reduce demand for highend products that rely on killing animals.
【小题1】The underlined word “reverse” in Paragraph 3 probably means ________.
| A．show | B．keep |
| C．follow | D．change |
| A．Jackie Chan and Ang Lee make fin soup popular |
| B．a lot of wild animals have been killed for products |
| C．Steven Spielberg's Jaws inspires us to protect sharks |
| D．the number of African elephants has been increased |
| A．More animals for highend products will be saved. |
| B．People have kicked the habit of having shark fin soup. |
| C．Shark fins will not be available any more in restaurants. |
| D．Global efforts have succeeded in stopping killing wild animals. |

DAVID Beckham. Cristiano Ronaldo and Rnfacl Nadal while you watch sports and admin* the players’ skills, do you ever notice how handsome the players are?
Yes, sportsmen tend to be handsome. And they haven’t only attracted the interest of the audience even scientists are now studying their good looks.
In a recent study, Erik Postma, a biologist at the University of Zurich in Switzerland, collected the headshots（头像）of 80 professional athletes from I hr 2012 Tour He France, a bicycle race held in Franco. The race, which covers 3,200 kilometers in 23 days, is often considered to In* one of the hardest endurance（耐力）events, according to The Telegraph.
Postma then asked female participants to score the cyclists’ attractiveness.judging them only based on their facial appearances. So, if a participant recognized any of the cyclists, meaning she knew how good he was at the sport, her score wouldn’t count.
After comparing all the scores with the cyclists’ performances in the 2012 race, Postma was surprised to find that the best riders were rated on average 25 percent more attractive than the worst ones. For example, one of the cyclists, Maxime Monfort , came third in terms of attractiveness and sixth in terms of performance, reported Discovery News.
But where did women get the ability to single out a good rider by simply looking at his face?
According lo Postma, evolution (进化) seems to be the answer. In ancient times, women preferred to marry strong men because they would provide good genes for their children. A man with great endurance was also able to cover long distances to hunt for food, which would allow him to better feed the family. “That’s why endurance performance was a key evolutionary factor.” Postma told Discovery News.
As you can see, it’s not that sportsmen ate more attractive themselves, women were just born to think of them that way.
Perhaps surprisingly, when Postma did the same test with male participants, he found that men actually had a quite similar view on which riders were handsome. Even
though most men aren’t aware of it. they inherited (继承) this ability from their ancient past, when it was necessary to “spot potential competitors” , explained Postma.
【小题1】What did Erik Postma ask female participants to do in his study?
| A．To help collect the headshots of professional cyclists from the Tour de France. |
| B．To pick out the cyclists whom they are familiar with or appreciate most. |
| C．To rate the cyclists’ attractiveness according to facial appearance. |
| D．To predict the cyclists ’ performances based on facial appearance. |
| A．The more attractive a cyclist was, the better he performed in the race. |
| B．Generally, a cyclist’s endurance had nothing to do with his attractiveness. |
| C．Attractive cyclists proved to have less endurance than those who were less attractive. |
| D．Those who performed best in the games were considered more attractive than those who performed worst. |
| A．Women and men hold quite different views on male attractiveness. |
| B．Men with good looks tend to lie less popular than men with great endurance. |
| C．A man with great endurance appealed to women in ancient times and this remains the same today. |
| D．Most men don* t have the same ability as women to single out a good sportsman by simply looking at his face. |

The earth is the only planet that scientists think has life. Why does the earth have life while the other planets (行星) don't? For one thing, the earth is just the right temperature. As the_third_planet from the sun, the earth seems to be just the right distance away. The planets which are closer to the sun are hot that their surfaces bake (烘烤) in the sun. The farthest planets are cold balls.
When the earth developed — which scientists believe may have happened about 4 billion years ago — many gases covered the earth. The gases caused the earth to be hot. But something wonderful happened. The temperature was just right for thick clouds to form. It rained very hard for a very long time. This gave the earth its oceans. Water made it possible for plants to grow. The plants created oxygen in the atmosphere. Oxygen is the gas that humans and animals breathe.
Only one other planet in the solar system seems to be something like the earth. That planet is Mars (火星). Mars is smaller than the earth, and it is quite a bit cooler. But it is not too cold for humans. On some days, the temperatures are as low as a winter day in the northern United States. If you wore a special space suit, you could walk around on Mars. You would have to bring your own air to breathe, the air on Mars is too thin to breathe.
Mars has the largest volcano (火山) in the solar system. It is sixteen miles high. The highest volcano on the earth is five miles high. The most unexpected (未预测到的) sight on Mars is dried up river beds. Scientists believe that Mars was once much better than it is now. Does this mean there could have been living things on Mars? Scientists are not sure, but there has been no sign so far.
【小题1】Which of the following is NOT the reason that the earth has life?
| A．The earth is just the right temperature. |
| B．The volcanos on earth are lower than those on Mars. |
| C．There is oxygen in the atmosphere of the earth. |
| D．The earth seems to be just the right distance away from the sun. |
| A．the Sun | B．the Moon |
| C．the Earth | D．the Mars |
| A．There could have been living things on Mars. |
| B．Mars has the largest volcano in the solar system. |
| C．There is almost no oxygen in the air on Mars. |
| D．Mars is smaller than the earth, and it is quite a bit cooler. |
