A mosquito is an insect that is found all over the world．There are thousands of different kinds of mosquitoes in many different sizes and colors．The female mosquito needs blood from vertebrates （脊椎动物）to lay eggs and produce more mosquitoes．She has a special part of her mouth that she uses to suck blood，and her saliva（spit）thins the blood so she can drink it．In fact．It’s the mosquito’s saliva that makes the bites itch（痒）!
A person who gets bitten by a mosquito will notice a wheal，which is a bump around the bite．
The wheal will be round，with pink or red around the edge and white in the middle．The wheal will witch a lot．Soon the wheal will disappear, but the itch will stay．
If you’ve been bitten by a mosquito，wash the bite with soap and waterk#s^5*u．Put on some calamine lotion to help stop the itching，or an adult can find an anti-itch cream at the drugstore for you．Placing an ice pack on the bite may also help．Tell an adult you’ve been bitten by a mosquito，especially if you live in the easterk#s^5*un United States．But if you develop an allergic reaction and feel dizzy or sick，tell a doctor immediately．He can treat allergic reactions with sole medicine．
The best way to avoid mosquito bites is to wear an insect repellent．Repellents that include one of these ingredients are best：BEET and lemon eucalyptus．Ask a parent to help you apply them．
Since mosquitoes lay their eggs in water，it’s also a good idea to empty out buckets，flower pots，toys and other things in your yard that may have collected water during a rainstorm．And when it’s possible，you’d better wear long-sleeved shirts and long pants to keep mosquitoes away from your skin．
60．What makes you itch after the mosquitoes’ bites?
A．A bump around the bite． B．The mosquito’s saliva．
C．Some calamine lotion． D．An antic-itch cream．

Get a reward for every bug you bring to live in new science museum exhibit.
In a city with trillions of American cockroaches(蟑螂), the Houston Museum of Natural Science has agreed to pay a quarter per bug－up to 1,000－as it seeks to populate a new insect exhibit alongside its Cockrell Butterfly Center.
Nancy Greig, the museum’s director insists the public payday for roaches isn’t just a marketing ploy(炒作).
“Absolutely, this wasn’t devised as a joke,” Greig said. “We needed more roaches for the exhibit, so I sent this message out to everyone in the museum asking people to bring them in. Well, someone decided to tell the press, and all hell has broken loose.”
“But we really do need cockroaches.”
“One might be forgiven for never considering how to catch a live cockroach. But it’s simple enough to fool them,” Greig said, “and even easier to catch them.” American cockroaches are the most common kind in Texas, measuring up to 2 inches long and invading homes.
Despite their less-than-attractive reputation, cockroaches actually aren’t that dirty. Greig even went so far as to call them “fastidious” saying they don’t enjoy rooting(用嘴拱食) in waste. They’re only dirty if, say, they used a sewer(下水道)line to gain access into a home.
The roaches collected by the museum will become part of a display in a new exhibit that showcases insects such as cockroaches, dung beetles and termites.
There’s more to like about roaches, too. They don’t bite, and they don’t carry diseases like a mosquito, so they’re generally safe to handle.
56．For what does the museum pay for cockroaches?
A．For a marketing ploy. B． It’s devised to make fun.
C．People really need them. D． For a new exhibit.
57．The underlined word “fastidious” probably means extremely ________.
A．clean B．dirty C．unpleasant D．fast
58．What do we know about American roaches?
A．It’s not easy for people in Houston to collect roaches.
B．They all measure 2 inches and are often found in homes
C．They don’t bite and they are free of disease.
D．We have reasons to like them.
59．Which of the following can serve as the best title for the passage?
A．The Houston Museum of Natural Science
B．A new exhibit
C．Quarters for cockroaches
D．A cockroach is lovely

For Americans, a mosquito bite is an itchy bother. But for many in Africa, a tiny bite can be deadly. One million people die each year of malaria, a disease spread by infected mosquitoes. Most of these people live in Africa, and are under age 5.
Malaria can be prevented and treated. However, many African nations don't have the funds to fight it. Nothing but Nets (NBN) hopes to change that. The United Nations Foundation created the campaign in 2006. The aim is to prevent malaria by covering sleeping areas with nets. Hanging bed nets treated with insecticide(杀虫剂) is the simplest way to stop mosquitoes from biting at night. The chemicals last four to five years. For $10, anyone can send a net to Africa and help save a life.
So far, NBN has raised $19 million and delivered 700,000 nets to seven countries. Families are taught how to use the nets. Kids also get vaccines (疫苗)and vitamins. "Women line up for miles to get the medicine for their kids," says NBN director Elizabeth McKee Gore. "They understand the importance."
So do kids in this country. "They get so excited thinking of ways to raise money," says NBN spokesperson and basketball star Ruth Riley.
NBN's biggest fund-raiser is Katherine Commale, 7. She's been spreading the information about bed nets for the past two years. To show how they work, she and her brother made a video. "We teach that bed nets can save lives," she said.
Katherine has raised $42,000 for NBN. "She just wants those who need a net to have one," says her mom, Lynda. "It's pretty simple to her." To find out how you can help, visit nothingbutnets.net.
We know from the passage that NBN is in fact _________.
A. a deadly disease B. an organization
C. a piece of equipment D. a game
The purpose of the passage is most probably ___________.
A. to list the sufferings of the African people
B. to introduce new ways to avoid mosquito bites
C. to call on people to offer their help to Africans
D. to tell people how to buy nets in Africa
By saying “So do kids in this country” in Paragraph 4,the author means that kids in this country also ___________.
A. know the importance of the bed nets
B. know how to protect themselves
C. lack nets to protect themselves
D. suffer from malaria
What do we know about Katherine from the passage?
A. She set up the website nothingbutnets.net.
B. She is the youngest money-raiser for NBN.
C. She raised money by making and selling videos.
D. She started working for NBN at the age of 5.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
It’s summertime-time once again for mosquitoes to make their appearance. And once they appear, mosquitoes are a total pain. They land on you, bite you, suck out some blood and leave behind an itchy welt（发痒的红肿）.
1 Female mosquitoes must find blood in order to reproduce, so mosquitoes come equipped with finely tuned sensors to help them locate the blood they need.
Mosquitoes’ weapons
Mosquitoes have perfected three different types of sensors. First, mosquitoes can sense several different chemicals. Mosquitoes can smell carbon dioxide and lactic acid（乳酸）up to 100 feet away. 2
Second, mosquitoes have very good eyesight. If you are wearing clothing that contrasts with the background, and if you move while wearing that clothing, mosquitoes can see you. It’s a good bet that anything moving is alive, and therefore full of blood.
Finally, mosquitoes come equipped with temperature sensors, so they can find warm-blood mammals and birds very easily.
3 The female mosquito sticks her proboscis（喙）into you. She sucks about five microliters of your blood into her abdomen.
After she has bitten you, some saliva（唾液）remains in the wound. 4 The area swells and you tich. Eventually, the selling goes away, but the itch remains until your immune cells break down the saliva proteins.
Our defense methods
Because mosquitoes are both a nuisance（讨厌的东西） and a danger, people prefer to stay away from mosquitoes. One way to do that is to use a chemical called DEET, which seems to black a mosquito’s chemical sensors. 5 In some cities there are even trucks that drive around town to spray for mosquitoes. Finally there are to traps. The most popular traps turn propane（丙烷） into carbon dioxide and warmth to attract mosquitoes. Over time, by catching large numbers of mosquitoes, these traps can cause the collapse of the mosquito population in the area.
| A．Another way to control mosquitoes is with insecticides（杀虫剂） that kill them. |
| B．How mosquitoes work is unknown to most of us. |
| C．Once a mosquito lands on you, it is time to bite. |
| D．Some bites of mosquitoes are more serious than you thought. |

Silence is unnatural to man．He begins life with a cry and ends it in stillness．In between he does all he can to make a noise in the world, and he fears silence more than anything else．Even his conversation is an attempt to prevent a fearful silence．If he is introduced to another person, and a number of pauses occur in the conversation, he regards himself as a failure, a worthless person, and is full of envy of the emptiest headed chatterbox （喋喋不休的人）．He knows that ninety-nine percent of human conversation means no more than the buzzing of a fly, but he is anxious to join in the buzz and to prove that he is a man and not a waxwork figure （蜡塑人像）．
The aim of conversation is not, for the most part, to communicate ideas; it is to keep up the buzzing sound．There are, it must be admitted, different qualities of buzz; there is even a buzz that is as annoying as the continuous noise made by a mosquito （蚊子）．But at a dinner party one would rather be a mosquito than a quiet person．Most buzzing, fortunately, is pleasant to the ear, and some of it is pleasant even to the mind．He would be a foolish man if he waited until he had a wise thought to take part in the buzzing -with his neighbors．
Those who hate to pick up the weather as a conversational opening seem to me not to know the reason why human beings wish 1:0 talk．Very few human beings join in a conversation in the hope of learning anything new．Some of them are content ．if they are merely allowed to go on making a noise into other people's ears, though they have nothing to tell them except that they have seen two or three new, plays or that they had food in a Swiss hotel．At the end of an evening during which they have said nothing meaningful for a long time, they just prove themselves to be successful conservationists．
1.According to the author, people make conversation to .
A．exchange ideas B．prove their value
C．achieve success m life D．overcome their fear of silence
2.By "the buzzing of a fly" （Para．1）, the author means"_____".
A．the noise of an insect B．a low whispering sound
C．meaningless talks D．the voice of a chatterbox
3.According to the passage, people usually talk to their neighbors___ ．
A．about whatever they have prepared
B．about whatever they want to
C．in the hope of learning something new
D．in the hope of getting on well
4.What is the author's purpose in writing the passage?
A．To discuss why people like talking about weather．
B．To encourage people to join in conversations．
C．To persuade people to stop making noises．
D．To explain why people keep talking．
