A

We bet that on cold wintry days, many of you love to stay in your warm home and, every now and then, come out into the kitchen for a snack. Unfortunately, plenty of creepy-crawly critters (爬行生物) like to do the same thing!

Winter is the time when bugs (虫子) invade your house without an invitation. The season can be tough for such creatures. In winter the air is cold, the ground is hard and many trees have no leaves. So bugs do what they have to do to survive.

Monarch butterflies head south to warmer climates. Ants crowd in deep underground colonies and eat food they have been storing all year. Many insects go into a deep sleep called diapause. There’re different kinds of diapause, but all are similar to hibernation, a time when bigger animals become inactive in the cold. Insects go into an inactive period, too, but it often isn’t when the temperature drops.

They rely on more dependable signals in the environment. For example, many insects can tell how much sunlight there’s each day. They use that to tell them when to shut down. Bugs are cold-blooded, meaning that their inside temperature is the same as the outside. They can’t move much when it gets below 40 degrees Fahrenheit. So they search for any warm place.

They’re looking for protection. These guys have been doing this for 300 million years, so they don’t really know they’re coming into your house. The home is a recent event in terms of their evolutionary behavior. They enter through tiny cracks or come in unnoticed on your clothes or shoes. Remember that they may be invading your homes for warmth and food, but they don’t care about humans.

56. What is the purpose of the first paragraph?

   A. To point out that humans like to stay at home in winter.

   B. To mean that humans and bugs have the same living habits.

   C. To mean that bugs will invade the house for their winter.

   D. To put forward the idea that bugs are not welcome in winter.

57. According to the text, what is diapause?

   A. It is the same as the animals’ hibernation.

   B. It often appears in warm areas all the year.

   C. It is done to keep bugs active in winter.

   D. It is a deep sleep similar to hibernation.

58. What often decides bugs’ diapause?

   A. The lower local temperatures.           B. The amounts of sunlight.

   C. Kinds of environmental signals.         D. The insects’ inside temperature.

59. According to the text, bugs invade humans’ homes to ______.

   A. attack humans                                 B. look for enough food

   C. seek for protection                           D. show their evolutionary results

Wugging, or web use giving, describes the act of giving to charity at no cost to the user. By using Everyclick.com, which is being added to a number of university computers across the UK, students can raise money every time they search, but it won’t cost them a penny.

    Research shows that students are extremely passionate(热情的)about supporting charity（慈善）--- 88％of full time students have used the Internet to give to charity. This figure is high because this age group is often the least likely to have their own income. 19％ of 22 to 24 year olds have short-term debts of more than￡5，000. With rising personal debt levels in this age group, due to university tuition fees or personal loans and a lack of long-term savings, traditional methods of donating to charity are often not possible.

    Beth Truman, a 21year old recent university graduate has used Everyclick.com to donate to her chosen charity, the RSPCA, for two years and has seen the “wugging” movement grow in popularity with students. “When you’re at university you become more socially aware, but it's sometimes hard to give to others when you have little money yourself,” says Beth. “Wugging is great for people in this age group as it allows them to use the technology on a daily basis to give to charity, without costing them a single penny.”

    Wugging is perfect for people who want to be more socially aware and supportive but don’t feel they have the means to do so. Students using the web can raise money for causes they care about without costing them anything in terms of time or money, and charities get a valuable source of funding.

    Everyclick.com works like any other search engine, allowing users to search for information, news and images but users can decide which of the UK’s 170,000 charities they would like to support through their clicks. Everyclick.com then makes monthly payments to every registered charity. Launched in June 2005, Everyclick.com is now the eighth largest search engine and one of the busiest charity websites in the UK.

1. According to the passage, “wugging” is actually a _______.

A. website                   B. charity-related action

C. school organization          D. student movement

2.How does Beth Truman think of the “wugging” movement?

A. It makes Everyclick.com popular in the UK. 

B. It makes giving to charity easy.

C. It results in students being more social awareness.

D. it stresses the importance of charity in people’s daily lives.

3.From the passage, we can conclude that _______.

A. most full time students contribute to charity on the Internet every day

B. Everyclick.com helps students pay for the college education

C. “Wugging” is a win-win idea for both students and charities

D. Everyclick.com is the most successful search engine in the UK

4.What would be the best title for this passage?

A. “Wugging”, a New Popular Term（术语）on the Internet

B. British People Show Strong Interest in Charity

C. More Britain Charities Benefit from the Internet

D. Students Raise Money for Charity by “wugging”

C

The Tasmanian devil is a rare marsupial(有袋动物)that lives only on the Australian island state of Tasmania. The doglike animal is rapidly disappearing. The Tasmanian state government estimates that the number of devils has dropped from around 150,000 in the mid-1990s to between 20,000 and 50,000 at the end of 2007.

The devil was declared an endangered species last week. It is being wiped out by a rare cancer called devil facial tumor(肿瘤)disease(DFTD). It spreads like a cold or flu from animal to animal. The disease is passed when one devil bites another. When the marsupial is infected with DFTD, large tumors develop around its mouth and neck. These growths make it impossible for the devil to eat. Many finally die from starvation within six months of being infected. As the name implies, the disease occurs only in Tasmanian devils and cannot be passed to humans.

You’ve got to remember that devils are scavengers(清扫工). They search through garbage for food. Throughout Tasmania people maintain outdoor dumps. If somebody threw out a carcass(兽类尸体), then the devils might actually consume quite large quantities of it.

The disease has not yet appeared in the devil population that lives in the northwest region of Tasmania. Conservationists have captured some of the healthy devils and sent them to a new home on the mainland of Australia. They hope these DFTD-free marsupials can be used to start a captive-breeding population. Once there are more disease-free devils, they can then repopulate the areas of Tasmania where the species are being wiped out.

Tasmanian devils play an important role in keeping the state’s ecosystem in balance. They keep the population of other predators, such as foxes and wild cats, in check. Ray Nias, head of World Wildlife Federation—Australia’s conservation program, says all Tasmanian wildlife will suffer if the devil becomes extinct. “If the devils go and the foxes and cats increase, it would be all over for a good dozen or more species of mammals, many of which are unique to Tasmania.”

46. It can be inferred that the Tasmanian devil is __________.

A. a hard-working street-cleaner                        B. a grass-eating animal

C. a meat-eating marsupial                                D. A DFTD origin

47. What’s the reason for making the Tasmanian devil endangered?

A. A rare disease called DFTD occurs in Tasmanian devils.

B. Dogs like to attack Tasmanian devils.

C. Tasmanian people try to wipe out Tasmanian devils.

D. The region of Tasmania is becoming hard for Tasmanian devils to breed.

48. To which question does the last paragraph give the answer?

A. How should people protect the devils?

B. What do the Tasmanian people do with the devils?

C. What happens if the devils disappear?

D. Which animal is closely related to the devils?

49. What measures do Tasmanian people take to stop the devils from being wiped out?

A. Trapping disease-free devils in a new place to breed more young devils.

B. Searching the cause of the disease and finding an effective treatment.

C. Developing new chemicals for the infected animals.

D. Moving all the devils to a new home on the mainland of Australia.

50. What’s true about DFTD?

A. It’s a disease that can be spread to human beings.

B. It’s a cold that occurs only in Tasmanian devils.

C. It’s a flu that Tasmanian devils get from their companions.

D. It’s a cancer that can be passed from one Tasmanian devil to another.

 A new survey finds that more than eighty percent of Internet users in the United States search for health information online. The survey found that searching online is one of the leading ways that people look for a second opinion though doctors are still the main source of health information.
Forty-four percent of people are actually looking for doctors or other providers when they search for health information online. Another finding of the survey: Two-thirds of Internet users look online for information about a specific disease or medical condition.
The Internet has also become an important source of emotional support for people with health problems. Susannah Fox says one in five Internet users has gone online to find other people who have the same condition. It was more popular among people with more serious health issues—one in four people living with chronic diseases (慢性病). And it was basically off the charts with people living with rare disease. They are so eager to find other people online who share their health concerns.
A disease is considered rare if it affects fewer than two hundred thousand people worldwide. The rise of social networking has made it easier for people with rare diseases to connect with each other and feel less alone. Social networking is also changing the way some doctors and patients communicate with each other. Dr. Jeff Livingston operates a medical center for women in Irving, Texas. His office uses password-protected software to share information with patients.
“We provide the patient full access to their medical care. Anything I can see, the patient can see. All of their notes, all of their doctor visits are right there. All of their lab work is right there.” Dr. Livingston says the software has increased efficiency, reduced costs and improved relations with patients.
【小题1】From the first paragraph, we can know _________.

D
Both warm-blooded and cold-blooded desert animals have ways to escape the desert heat. Warm-blooded desert animals, such as rats and mice, rest during the day, often staying in cool underground burrows. At night they search for food. Animals that are out during the day, such as cold-blooded lizards and snakes, are active only for short periods. As their body temperature rises, these reptiles move into the shade in order to cool down. In the early evening, when the sun grows weaker, the reptiles become more active and begin their search for food again.
Getting enough water to survive is a major problem for all desert animals. Some desert animals, such as the kangaroo rat and the related jerboa, get water only from the food that they eat. Because these animals eat mainly dry seeds, they must survive on a tiny amount of water.
Most deserts have only a small number of frogs and toads because these animals must be near water to survive. Yet even these creatures have adapted to desert conditions. When small amounts of water collect in temporary streams, the desert-living frogs and toads become active. After a rainfall, they lay their eggs. The eggs grow into tadpoles in a few days and into adults in just four weeks. When the puddles dry up, the adult frogs or toads dig into the ground. Their metabolism(新陈代谢) slows, and they stay beneath the ground until the next rain, which may be as good as a year away. Until then, their bodily activities continue at a reduced rate.
The camel---often called the ship of the desert---is one of the most successful desert animals. Camels can go for long periods without water, but eventually they must drink. When water becomes available to them after a long drought, they may drink 95 liters of water or more. When water is not available, what helps camels survive the desert heat is the fat stored in their humps. A camel’s hump contains about 12 kilograms of fat. Fat is rich in hydrogen. As the fat is digested, hydrogen from the fat combines with oxygen in the air that the camel breathes. The result is H2O, or water. Each kilogram of fat that a camel digests produces about a liter of water.
