Warm water freezes（结冰） more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year a Canadian scientist George Kill proved the English professor was right. Dr Kill filled an open oil pail(桶) with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first. The lack of covers on the pails is the secret. Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen. And so the warm water froze faster than the cold water even though it had a greater temperature drop to make.
Hundreds of years ago, Sir Francis Bacon found _______.

A．the temperature of warm water drops faster than that of cold water

B．warm water is heavier than cold water

C．warm water has the same temperature as cold water

D．warm water is not as useful as cold water

What Sir Francis Bacon said was right, but people didn't believe him until _______.

A．late in the 19th century	B．early in the 20th century
C．three years ago	D．late in the 20th century

Leave a pail with warm water and another pail with cold water in the same low temperature, you’ll find that _______.

A．cold water freezes first

B．warm water turns into ice before cold water

C．warm water and cold water freeze at the same time

D．much of cold water is changed into air.

Why does warm water freeze first in the same freezing weather?

A．Because some of the warm water turns to vapor, the amount(数量) becomes less than that of cold water.

B．Because warm water is lighter than cold water.

C．Because the temperature of warm water is lower than that of cold water.

D．Because cold water freezes with more difficulty than warm water.

There is an English saying: "Laughter is best medicine." Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people's health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercises. It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated(忍受) the pain for the longest time was the groups which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain.
As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.
63. Doctors have proved the following except that ____________.
A. smiling does good to health                   B. laughter can be tolerated
C. there is a way to reduce pain                  D. laughter can work the muscles in the feet
64. The main idea of the passage is ____________.
A. laughter and physical exercises have similar effects on the human body
B. smile can produce the same effects as laughter
C. pain can be reduced by laughter
D. laughter is best medicine
65. The underlined word "diminish" is similar to____________.
A. test            B. stop           C. reduce            D. increase
66. Doctors hold laughter clinics _____.
A. to give better condition to their patients
B. in order to improve patients' health
C. to make patients smile
D. to prove smile and laughter have the same effect

Tea drinking was common in China for nearly one thousand years before anyone in Europe had ever heard about tea. People in Britain were much slower in finding out what tea was like, mainly because tea was very expensive. It could not be bought in shops and even those people who could afford to have it sent from Holland did so only because it was a fashionable curiosity. Some of them were not sure how to use it. They thought it was a vegetable and tried cooking the leaves. Then they served them mixed with butter and salt. They soon discovered their mistake but many people used to spread the used tea leaves on bread and give them to their children as sandwiches.
Tea remained rare and very expensive in England until the ships of the East India Company began to bring it direct from China early in the seventeenth century. During the next few years so much tea came into the country that the price fell and many people could afford to buy it.
At the same time people on the Continent were becoming more and more fond of tea. Until then tea had been drunk without milk in it, but one day a famous French lady named Madame de Sevigne decided to see what tea tasted like when milk was added. She found it so pleasant that she would never again drink it without milk. Because she was such a great lady her friends thought they must copy everything she did, so they also drank their tea with milk in it. Slowly this habit spread until it reached England and today only very few Britons drink tea without milk.
At first, tea was usually drunk after dinner in the evening. No one ever thought of drinking tea in the afternoon until a duchess(公爵夫人)found that a cup of tea and a piece of cake at three or four o’ clock stopped her getting “a sinking feeling” as she called it. She invited her friends to have this new meal with her and so, tea-time was born.
59. Which of the following is true of the introduction of tea into Britain?
A. The Britons got expensive tea from India.
B. Tea reached Britain from Holland.
C. The Britons were the first people in Europe who drank tea.
D. It was not until the 17th century that the Britons had tea.
60. This passage mainly discusses ____________ .
A. the history of tea drinking in Britain
B. how tea became a popular drink in Britain
C. how the Britons got the habit of drinking tea
D. how tea-time was born
61. Tea became a popular drink in Britain____________.
A. in the eighteenth century           B. in the sixteenth century
C. in the seventeenth century          D. in the late seventeenth century
62. We may infer from the passage that the habit of drinking tea in Britain was mostly due to the influence of _________.
A. a famous French lady      B. the ancient Chinese
C. the upper social class      D. people in Holland

Two thieves came to a house to steal something. They dug a hole in the wall of the house.
There lived many mice in the house. The woman in the moonlight saw a mouse crawl(爬行) into the house. “Look! In comes one,” she said to the man in the house. The thief was so frightened that he hurriedly crawled out of the house and said to the one waiting outside, “She found me when I was just in.” But the thief outside didn’t believe him, so he said, “Let us two try to crawl into the house together.” At that time two mice happened to crawl into the house, too. The woman saw the mice and shouted, “In come two, catch them!” The two thieves were terribly frightened. The man in the house said, “You saw them come in but where are they? I will catch them tonight.” The two thieves started running away at once.
The two thieves wanted to make it clear whether they had been found or not the night before. The next day they acted as men selling sweet potatoes and came before the house. The man and the woman were ploughing in their fields. The rein(缰绳)broke and the woman came home for a rope. She saw two men selling sweet potatoes and wanted to buy some. She picked out two which looked like mice. At the time the man couldn’t wait for her any longer in the fields and he ran back from the fields to hurry her up. The woman showed the sweet potatoes to the man and said, “How they look like the two of last night.” The man said, “I asked you to fetch a rope, why don’t you hurry for it?” The two thieves ran away very quickly without their sweet potatoes.

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 about supporting charity -- 88% of full time students have used the Internet to give to charity. 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 appealing (有感染力的) or possible.
Beth Truman, a 21 year 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.
67. According to the passage, "wugging" is actually ________.
A. a website   B. a charity-related action C. a school organization D. a student movement
68. In the case of charity, Everyclick.com ________.
A. frees students of the financial worries    B. receives much money from students
C. offers valuable information to students    D. praises students for their money-raising
69. From the passage, we can conclude that ________.
A. most full time students do charity on the Internet every day
B. Evervclick.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
70. What would be the best title for this passage?
A. "Wugging", a new popular term 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".

The H1NI flu outbreak has resulted in the first death outside Mexico today -- a 23-month-old child in Texas.
Three more cases were confirmed in the UK, adding to the two previously disclosed in Scotland.
A 12-year-old girl is among five people in the UK to have contracted HIN1 flu after visiting Mexico, Gordon Brown told the Commons during prime minister's questions.
Two adults -- one from Birmingham and one from London -- are undergoing treatment.
More than 150 people are suspected to have died of the virus in Mexico and the illness has spread around the globe, but news of the first death outside the country where it originated will increase fears that a pandemic (流行病) could develop.
The infant's death from H1NI flu in the US was confirmed by Dr Richard Besser, the acting director of the Centers for Disease Control and Prevention. He gave no other details about the child.
America has confirmed 65 cases of HIN1 flu, most of them mild, but Besser said more deaths were likely.
"HIN1 Flu is a very serious infection and each virus is unique so it' s hard to know what we' re going to be seeing, but given what we've seen in Mexico we have expected that we would see more severe infections and we would see deaths," he said.
It was unclear if the girl had contracted the illness in Mexico, or been infected in the US.
Confirmation that infected people in two countries are spreading the new disease to their families or contacts n a sustained way would meet the World Health Organization's (WHO) criteria (标准) for declaring a phase five alert on its scale of one to six. It raised the level from three to four on Monday as the virus moved to Europe.
The WHO spokesman Gregory Hard told reporters yesterday, "If we have a confirmation from the United States or Canada, we could move to phase five."
64. How many cases of HINI flu are there in the UK?
A. One. B. Two. C Three D. Five.
65. According to Dr Richard Besser, why is it hard to predict what things will be like?
A. Because more than 150 people have died of the virus in Mexico.
B. Because H1 N1 flu is a very serious infection and each virus is unique.
C. Because the infections are severe and there will be more deaths.
D. Because the WHO has raised the alert level from three to four.
66. What's the main idea of the news?
A. More cases of H1NI flu were confirmed in the UK.
B. It's hard to deal with the HINI flu.
C. H1NI flu caused death outside Mexico.
D. "The WHO will raise the alert level.
