You¡¯ve heard it repeatedly: Make sure you drink at least eight glasses of water per day. The key words are "at least", because, unless you are a child, you need more water than that. The rule is, for every 50 pounds of body weight you carry, drink one quart of bottled or filtered (¹ýÂ˵Ä) water per day. The average person weighs 150 pounds, so they should drink three quarts per day. A 200 pounds person should drink a full gallon per day. Athletes should drink even more than that. Follow these and you¡¯ve adopted one of the most important health habits.
Our bodies are mostly water, and water is essential to our every function. Drink the appropriate amount, and everything is much more likely to function at the best levels. If you don¡¯t drink enough water, over the short term you will experience tiredness, dry skin, headaches and constipation (±ãÃØ); over the longer term, every body function will degrade more quickly. It really is as simple as that.
Things get a bit more complicated in what type of water to drink. Bottled water and filtered water are both good options. Do not drink tap water or distilled water (ÕôÁóË®).Bottled water should be bottled in clear glass containers, not the plastic containers that transfer far too many chemicals into the water. Filtered water can be obtained through low-cost filters.
Tap water should be avoided because it contains chlorine (ÂÈ) and may contain fluoride (·ú»¯Îï), which is poisonous and can have terrible consequences for the body. Distilled water should also be avoided because it can burn up your body of necessary minerals. It has been tied to hair loss, which is often associated with certain mineral lack.
Finally, drink water at room temperature if possible, as ice-cold water can harm your stomach.
1.What¡¯s the meaning of the underlined word ¡°degrade¡±?
A. Improve. B. Reduce.
C. Strengthen D. Recover.
2.What kinds of water are proper for drinking?
A. Tap water and bottled water.
B. Tap water and distilled water.
C. Bottled water and filtered water.
D. Distilled water and filtered water.
3.What¡¯s the main reason that distilled water isn¡¯t recommended to drink?
A. It leads the body to lack certain minerals.
B. It isn¡¯t clean enough to drink.
C. It contains too many chemicals.
D. It contains fluoride.
4.Which of the following statements is NOT true according to the passage?
A. It is harmful to drink plenty of icy water.
B. One may feel tired due to lack of water for a short time.
C. The water with chlorine is not suitable to drink.
D. The water in plastic containers is safe to drink.

With brown curly hair and a pair of glasses, 19-year-old Nicholas Allegra from New York state, US, looks like a real-life Harry Potter. However, rather than waving a wand, Nicholas is a "wizard " at "jailbreaking ". This is probably why he ended up with an internship at Apple, a job many of his fellow Brown University students dream of.
Jailbreaking is the process of removing the limitations set by Apple on devices with the iOS operating system. These devices include the iPhone, iPod Touch, and iPad. It allows users to gain full access to the operating system and download additional materials that are unavailable through the official Apple App Store. However, it is estimated that Apple loses $100 million (640million yuan) from jailbreaking each year.
Nicholas, with a famous nickname "Comex", is the teenage hacker behind the jail-breaking site JailbreakMe. com. The site tells users how to unlock their iPhones using software that is not approved by Apple. The jailbreaking software he made has been downloaded millions of times by users around the world.
Then Forbes magazine suggested in an article that Apple's security team might need him as a new intern. It seems that they do. Little more than a day after Steve jobs stepped down as CEO, Apple welcomed Nicholas Allegra. Nicholas wrote on his Twitter on August 26 that " It's been really, really fun, but it's also been a while and I've been getting bored. So, the week after next I will be starting an internship with Apple.
Apple is not the only company embracing the skills of hackers. Facebook recently hired iPhone jailbreaker George "Geohot" Hotz as a full-time employee.
However, there are still hot debates about whether employing hackers is a wise solution. The word "hacker" has always had a double meaning. In the press, "hacker" means someone who breaks into computers. They steal from people's bank accounts, download sensitive information and attack legal websites. Among computer lovers, it means a cool programmer who can make a computer do whatever he wants.
Hiring a hacker does have its advantages. A talented hacker is probably quite capable of finding problems and suggesting corrections. On the other hand, because of a hacker's former behavior, many people doubt their morals .Can the company trust them with its valuable assets ? And can someone who is so used to working alone in the dark fit into a new role within a company?
One thing is for sure- Comex isn't the first member of the hacker community to land the job of his dreams. It's likely that he won't be the last.
1.What did Nicolas Allegra do before working for Apple?
A. He was a wizard.
B. He designed software for Apple.
C. He ran an Apple app store.
D. He set up JailbreakMe. com.
2.According to the article, jailbreaking _______.
A. enables iPhone users to access more functions on their phones
B. doesn't cause much financial loss to Apple
C. destroys the operating system of Apple products
D. helps promote Apple products around the world
¡¾Ð¡Ìâ3 The underlined word "embracing" in Paragraph 5 is closest in meaning to
A. praising B. Preventing
C. accepting D. protesting
3.Some people think it unwise to hire hackers because they _______.
A. are likely to quit their job very quickly
B. are not reliable and adaptable enough
C. lack professional problem solving skills
D. are used to working at night rather than in the daytime

Greg Evans started to study film at Ryerson University, but had a change of heart and switched to social work at George Brown College in second year£®Yet the college recognized only one of Evans' general-interest credits£¨Ñ§·Ö£© from Ryerson , and also made him take English all over again although he had passed it at university£®
¡°So I spent time and money taking a course I had already taken before¡±, complained Evans£®"The system really needs to change£®" Evans was part of a chorus of Ontario students on Monday cheering a new $ 73£®7 million five-year plan to help students switch from college to university, and from university to college£®
After years' of urging from students, the Ontario government set up a new Credit Transfer Innovation loud to help students move back and forth between the more hands-on courses of community college to the often broader academic focus of a university degree£®" We hear horror stories about students who can't get recognition from one institution for a very similar course at another, and in one case I believe the same professor was teaching them both," noted Malloy after announcing the new fund£®
Individual colleges and universities have decided on nearly 500 joint deals to honor each other's credits in certain courses£®Each school is required to set targets for more credit-transfer agreements, and link these increases to provincial funding£®
More than 4,000 college graduates transfer £¨×ª»»£© to university in Ontario every year twice as many as eight years ago, noted Justin Fox, president of the College Student Alliance£®Yet Ontario universities and colleges have been cautious about transferring credits, in part to avoid copying each other's courses, noted Bonnie Patterson, president of the Council of Ontario Universities ,who welcomed the increased flexibility£®

A wide range of factors can lead to exam stress for a child. However, such stress can be prevented if parents encourage their children to complete their studies on time. And if they enjoy studying, the stress can be prevented or at least reduced. 1. .
Help him or her prepare. Teach your child the importance of discipline. Long before the exams, you need to have all the facts regarding your child¡¯s progress and a clear picture of his or her academic status. Based on this, you can help your child create a routine before the exam. 2. .
Allow your child some free time. 3. . It is part of regular life, and especially during exams, when stress levels are running high, it is natural for your child to feel like having free time at some point during the day. Let him or her have it, and just do anything with in. If your child is just sitting around, don¡¯t disturb his or her thoughts.
4. . Every household has conflict, especially when children are involved. Exams are a time when you need to be a little helpful. Be firm in maintaining the regular schedule and discipline, but at the same time be understanding towards your child¡¯s needs. 5. . Give your children the freedom to study in his or her own way. But make sure that at the end of the day everything required has been studied.

What will power your house in the future£¿Nuclear£¬wind£¬or solar power£¿According to scientists at the Massachusetts Institute of Technology(MIT)in the US£¬it might be leaves¡ªbut artificial(ÈËÔìµÄ)ones.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis(¹âºÏ×÷ÓÃ)£®Now researchers have found a way to imitate this seemingly simple process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts(´ß»¯¼Á)£®Similar to natural leaves£¬it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell£¬which uses those two materials to produce electricity£¬located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card£¬scientists claimed that it is promising to be an inexpensive source of electricity in developing countries.¡° One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology£¬¡±said Nocera at a conference of the American Chemical Society.
The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf£¬by contrast£¬is made of cheap materials£¬easy to use and highly stable. In laboratory studies£¬Nocera showed that an artificial leaf prototype(ÔÐÍ)could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera's recent discovery of several powerful£¬new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now£¬the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides£¬the device can run in whatever water is available£»that is£¬it doesn't need pure water. This is important for some countries that don't have access to pure water.
With the goal to ¡°make each home its own power station¡± and ¡°give energy to the poor¡±£¬scientists believe that the new technology could be widely used in developing countries£¬especially in India and rural China.
1.Which of the following orders correctly shows how the artificial leaf is used to produce electricity?
a£®artificial leaves split water into hydrogen and oxygen
b£®the hydrogen and oxygen gases are stored in a fuel cell
c£®the artificial leaves are put in water
d£®the fuel cell uses hydrogen and oxygen to produce electricity
A£®c£¬b£¬a£¬d B£®c£¬a£¬b£¬d
C£®b£¬c£¬a£¬d D£®c£¬a£¬d£¬b
2.The purpose of the scientists at MIT in developing the new artificial leaf is to________.
A£®build up more power stations in the world
B£®provide cheaper energy for developing countries
C£®offer people in developing countries access to pure water
D£®gain a deeper understanding of the photosynthesis process
3.The main idea of this passage is ________.
A£®an introduction to the history of artificial leaves
B£®an invention copying photosynthesis
C£®giving energy to the poor
D£®a mixture of water power and solar energy
