Winter begins in the north on December 22nd. People and animals have been doing what they always do to prepare for the colder months. Squirrels (松鼠), for example, have been busy gathering nuts from trees. Well, scientists have been busy gathering information about what the squirrels do with the food they collect.
They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut (黑胡桃) trees. The black walnut is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests.
Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls “death traps for seeds”.
Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century.
The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.The study done by Rob Swihart and Jake Goheen is to ________.
| A．find out the living conditions for squirrels |
| B．learn squirrels’ influence on black walnut trees |
| C．do something to get rid of squirrels |
| D．save the forests in the American state of Indiana |
The difference between gray squirrels and red squirrels mainly lies in ________.
| A．the way they gather the walnut |
| B．the time they have winter sleep |
| C．the place they have winter sleep |
| D．the place they store the walnuts |
When Professor Swihart says “death traps for seeds”, he actually means that ________.
| A．red squirrels eat more nuts than gray squirrels |
| B．gray squirrels and red squirrels will have severe fights |
| C．nuts above the ground will not develop into plants |
| D．seeds can be traps for other animals in the forest |
According to the passage, which of the following is true?
| A．The black walnut is equally attractive to both gray and red squirrels. |
| B．Gray squirrels do more harm to the forest than red squirrels. |
| C．Red squirrels and gray squirrels have helped the spread of walnut trees. |

We are all busy talking about and using the Internet, but how many of us know the history of the Internet?
Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way, computer network system would keep on working all the time.
At first, the Internet was only used by government, but in the early 1970s, universities, hospitals, and banks were allowed to use it too. However, computers were still expensive and the Internet was difficult to become cheaper and easier to use. Scientists also developed software that made “surfing” the Internet more convenient.
Today it is easy to get-on-line and millions of people use the Internet every day. Sending e-mails is more and more popular among students.
The Internet has now become one of the most important parts of people’s life.The Internet has a history of ______ years.
| A．more than 40 | B．less than 30 |
| C．more than 60 | D．more than 50 |
Scientists set up a new network system to ______.
| A．make the computer cheaper | B．use the computer widely |
| C．make the computer go well | D．develop new software |
When did the Internet begin to be used in hospitals?
| A．In the 1960s. | B．In the 1970s. |
| C．In the 1980s. | D．In the 1990s. |
In the 1960s, if one computer in the network broke down, the whole network ______.
| A．still worked | B．stopped to work |

| A．How to Surf the Internet |
| B．How to Use the Internet |
| C．When was the Internet set up |

When the musical sound rings you, you immediately reach for your pocket ready to have a chat. But although you probably use it all the time, have you ever thought about the manners related to talking on the phone? If you haven’t, here are some tips to guide you.
●Always give the person you are calling plenty of time to get to the phone before you hang up. If the person who answers is not the one you want, give your name and ask if you may speak to the person you want.
●Think about the time you call people. Try not to call too early in the morning (before about 9:00) or too late at night (after about 9:30). Also try not to call at mealtimes.
●If you go by plane to visit your relatives at Christmas, remember to follow airline instructions. Cell phone must be turned off as soon as the plane doors are closed and remain so until the doors open again on arrival.
●When you’re face to face with someone, do not talk on the phone. It is rude to be on the phone when a waiter is trying to take your order in a restaurant, or when you are returning the shoes you have just been trying on in a shop. Finish any face-to-face business before taking a call. Continuing to use the phone while nodding to the person in front of you is quite impolite.
●When in a restaurant with your friends, keep phone conversations short. Make a call only if it is important. Practice speaking in a low voice. If no one turns to your way, you’ve got it.
●If you go to a theatre, a concert or a cinema, consider the other people around you. Check that your phone is “off” before you enter. If you are expecting a very important call, put your phone on “vibrate”(振动) and run for the exit as soon as you feel it. If you forget both “off” and “vibrate” and your phone rings, don’t answer it, turn it off straight away.Which is TRUE according to the passage above?

As we all know, the Dragon Boat Festival is our country’s traditional festival, but do you know there is also a Dragon Boat Festival in South Korea, which also falls on May 5 of the luar calendar(阴历)? It has been reported that South Korea will apply to United Nations Educational, Scientific and Cultural Organization (UNESCO 联合国教科文组织) to make the celebration of the Dragon Boat Festival its own intangible cultural heritage (非物质的文化遗产). If successful, people from other countries may see the Dragon Festival as a Korean creation.
As the birthplace of the yearly event more than 2,000 years ago, China is not happy with the situation. "It would be a shame if another country successfully made a traditional Chinese festival part of its own cultural heritage ahead of China," said Zhou Heping, deputy(副) culture minister. The Ministry of Culture is even thinking of making its own application to UNESCO, covering all traditional Chinese festivals, including the Dragon Boat event.
It is thought that the festival is held in memory of the great poet Qu Yuan (340-278 BC), who lived in the State of Chu during the Warring States Period. Qu was known to be a patriot (爱国者) and admired by ordinary people.
He is said to have jumped into Miluo River, because he had lost hope in his country's future. When people heard about Qu's death, they sailed up and down the river searching for his body. They also beat the drums to frighten away the fish and threw Zongzi into the water to stop the fish touching Qu. Dragon boat racing is said to come from this search for the poet's body.

I know what you’re thinking：pizza? For breakfast? But the truth is that you can have last night’s leftovers in the a. m. if you want to.
I know lots of women who skip breakfast, and they have a ton of different excuses for doing it. Some say they don’t have time, others think they’re “saving” calories（卡路里）, still others just don’t like breakfast food.
But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all，”says Katherine Brooking, R. D.，who developed the super-easy eating plan for this year’s“SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself', “You can always eat it tomorrow, ”I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.The word “leftovers” in Paragraph 1 probably means __________.
| A．pizza topped with fruit |
| B．things left undone |
| C．meals made of vegetables |
| D．food remaining after a meal. |
According to the last paragraph, it is important to__________.
| A．eat something for breakfast |
