Eat nuts, live longer. Researchers have found that those who eat a handful of peanuts every day significantly decrease their risk of dying from all causes compared to those who do not eat nuts. A new study concludes that all types of nuts seem to be protective.
Researcher Ying Bao is with the Department of Medicine at Brigham and Women’s Hospital and Harvard University Medical School in Boston, Massachusetts. She and her colleagues looked at the impact of nut consumption by analyzing two huge studies that began in 1980 - the Nurses’ Health Study, which tracks the well-being of more than 76,000 women, and 42,000 men enrolled in the Health Professionals Follow-up Study.
Among the questions asked at the beginning of the studies was, 'how frequently do you eat nuts?' The information was updated every two to four years. Bao says the participants were followed for three decades.
“What we observed is that people who eat more nuts are less likely to die over the next 30 years," said Bao. "So, for example, if a person eat(s) nuts once per day, that person has a 20 percent lower risk of dying.”
Bao says eating a handful of nuts five or more times per week was associated with a 29 percent reduced risk of dying from heart disease and an 11 percent lower risk of cancer death. A serving size is 28 grams.
Nuts contain nutrients, including high quality proteins, vitamins and minerals, all of which have anti-cancer effects and may help protect the heart.
Bao says researchers are planning studies to find out how nuts are beneficial to human health.
The study on the health benefits of nuts was funded by the International Tree Nut Council Research and Education Foundation.
People who often eat nuts ________.

A．are more likely to live longer than people who often eat fruits

B．don’t need to go to hospital

C．may live longer than people who don’t eat nuts

D．don’t have to do sports

The underlined word “well-being” in Paragraph 2 shares the same meaning as “________”.

A．illness

B．health

C．diet

D．habit

About Bao’s research, which statement is true?

A．She has done the research by herself.

B．Her research was based on two studies.

C．Her research lasted about three years.

D．People should eat all kinds of nuts every day.

Eating nuts may help us stay away from ________.

A．cancer

On October 12, 1989, some Chinese scientists were working at the computers to look for information they needed. Suddenly they saw a lot of very bright spots crossing the computers’ screens. At the same time, the computers were working much slower. To find out what was happening they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses! Obviously all these computers had been infected （传染）by computer viruses.
It is said that the computer viruses were made by a group of young men fond of playing tricks. They all had excellent education. They created the viruses just to show their intelligence. These kinds of computer viruses are named Jerusalem Viruses. These viruses can stay in computers for a long time. When the time comes they will attack the computers by lowering the function, damaging their normal programs or even getting rid of all the information.
We now come to know that Jerusalem Viruses often attack computers on Fridays and that they are spreading to a lot of computers. Among the countries that suffered computer viruses last year are Britain, Australia Switzerland and the US. But till now, how to get rid of the terrible viruses remains a problem.

Fire fighting is a serious matter. Knowing what to do during a fire can save people’s lives. It is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency exits, but not elevators（电梯）.
From the lower floors of buildings, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury.
The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked into the room.
On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury. Bushes and trees can help you to have a soft landing.
1. Which of the following should not be used when trying to escape from a fire?
A. windows       B. elevators        C. fire exits        D. stairways
2. How far from the ground is the second floor window?
A. about 12 feet                        B. about 6 feet
C. about the height of an average man        D. nearly 10 feet
3. According to the passage, windows are _______ of escaping a fire.
A. the only way                        B. the best way
C. safer than any other ways              D. one of the possible ways
4. The writer suggests that ________.
A. breathing in smoke might be harmful
B. smoke will enter the room through an open window
C. fresh air can’t reach the second floor window
D. to keep you head low will help to escape a fire
5. If you are on the second or third floor when a fire breaks out, you’d better ______.
A. drop directly onto the ground
B. first drop onto a roof then onto the cement
C. drop from a roof window then onto bushes or trees
D. drop onto the cement rather than bushes and grass

It was at least two months before Christmas when nine-year-old Almie Rose told her father and me that she wanted a new bicycle. As Christmas drew nearer, her desire for a bicycle seemed to fade（消退）, or so we thought. We bought her a lovely doll, and a doll house. Then, much to our surprise, on December 23rd, she said that she “really wanted a bike more than anything else.” But it was just too late. With such a lot of preparations to do for the Christmas dinner we did not have the time to buy our little girl a bike. So, here we were Christmas Eve around 9:00 p.m., with Almie and her six-year-old brother, Dylan, sleeping in their beds. Now we could only think of the bicycle and the disappointment of our child. “What if I make a little bicycle out of clay (泥) and write a note that she could trade（交易，交换） the clay bike in for a real bike?” her dad asked. So he spent the next four hours making a tiny clay bike. On Christmas morning, we were excited for Almie to open the little gift box with the beautiful red and white clay bike and the note. Finally, she opened it and read the note aloud. “Does this mean that I can trade in this bike that Daddy made me for a real one?” I said, “Yes.” Almie had tears in her eyes when she replied, “I could never trade in this beautiful bicycle that Daddy made me. I'd rather keep this than get a real bike.” At that moment, we would have moved heaven and earth to buy her every bicycle in the world!

Here are a few tips we’ve put together to help you learn English well.
Speak, speak, speak!
Practise speaking as often as you can—even speaking to yourself is good practice. Try recording yourself whenever you can. Compare your pronunciation with the master version, see how you can do better and have another try. If you do this several times, you will find that each version is better than the last.
Why not learn with someone else?
It helps if you can learn with someone else. If you can persuade a friend or family member to study with you, it will make you keep working. Agree times to meet and set goals for the week, and test each other regularly.
Don’t get stuck by a word you don’t know
Practise improvising (即兴的) ways of getting your meaning across while speaking spontaneously (本能), even if you don’t know the exact words or phrases. Think of things you might want to say whenever you have spare time. A basic example is the use of tenses. If you don’t know the past tense but want to talk about yesterday, use the verb in the present tense and use the word for “yesterday”. Use facial expressions, hand movements, anything to get your meaning across.
Language learning is also about intuition (直觉)
Guesswork is important in learning a new language. When listening to recorded material, you aren’t expected to understand everything first time round. If you play the same piece several times, you will most probably understand something new each time. Learn to make maximum use of all the clues you can pick up. For example, what do the speakers sound like? Happy? Angry? Calm? Etc.
Build up your vocabulary
A wide vocabulary is the key to successful language learning but don’t try to learn too much at once. It’s best to study frequently, for short periods of time. Take a maximum of six or seven items of vocabulary and learn them. Put them into sentences to fix them in your mind, then come back to them later. Much of the vocabulary in the course is presented by topic.
And above all, have fun!
1. Why should one have himself recorded when practicing speaking?
A. To encourage others to start.
B. To record his own progress.
C. To improve his speaking.
D. To compare himself with others.
2. Which of the following is the most important in learning English?
A. Speaking.      B. Pleasure.      C. Intuition.     D. Vocabulary.
3. It is important in Tip 3 that        is helpful when you are learning English.
A. body language B. a good memory C. a good friend D. a proper dictionary
4. Which of the following seems NOT to be true in learning a language?
A. Practice makes perfect.           B. A good beginning is half done.
C. Rome is not built in a day.        D. Don’t run before you can walk.
5.The underlined word “maximum” in Paragraph 5 might mean ________________.
A. 小心的             B. 大胆的         C. 最小量的           D. 最大量的
