Put an ice cube from your fridge into a glass of water. You have a piece of string(线) 10 centimeters long. The problem is to take out that piece of ice with the help of the string. But you must not touch the ice with your fingers.
You may ask your friends to try to do that when you are having dinner together. There is a saltcellar on the table. You must use salt when you carry out this experiment.
First you put the string across the piece of ice. Then put some salt on the ice. Salt makes ice melt(融化). The ice round the string will begin to melt. But when it melts, it will lose heat. The cold ice cube will make the salt water freeze again. After a minute or two you may raise the piece of string and with it you will raise your piece of ice!
This experiment can be very useful to you. If, for example, there is ice near the door of your house, you must use very much salt to melt all the ice. If you don’t put enough salt, the water will freeze again. We must use _______ when we carry out this experiment.
| A．fridge | B．some food | C．a table | D．some salt |
How long will it take to carry out this experiment?
| A．More than three minutes. | B．Five minutes or so. |
| C．Only one minute or two. | D．About ten minutes. |
What is the task of this experiment?
| A．Put the ice cube into the glass of water with the help of the string. |
| B．Take out the ice cube in the glass of water with the help of the string. |
| C．Take out the ice cube in the glass of water with your fingers. |
| D．Put some salt on the ice cube and then put the string across it. |
How many things at least are used in this experiment?
| A．Three. | B．Four. | C．Six. | D．Seven. |
We can learn something about _______ from the passage.
| A．physics | B．biology | C．chemistry | D．maths |
Scientists today are making greater effort to study ocean currents (洋流) . Most do it using satellites and other high-tech equipment. However, ocean expert Curtis Ebbesmeyer does it in a special way -- by studying movements of random floating garbage. A scientist with many years’ experience, he started this type of research in the early 1990s when he heard about hundreds of athletic shoes washing up on the shores of the northwest coast of the United States. There were so many shoes that people were setting up swap meets to try and match left and right shoes to sell or wear.
Ebbesmeyer found out in his researches that the shoes — about 60,000 in total — fell into the ocean in a shipping accident. He phoned the shoe company and asked if they wanted the shoes back. As expected, the company told him that they didn't. Ebbesmeyer realized this could be a great experiment. If he learned when and where the shoes went into the water and tracked where they landed, he could learn a lot about the patterns of ocean currents.
The Pacific Northwest is one of the world's best areas for beachcombing(海滩搜寻) because winds and currents join here, and as a result, there is a group of serious beachcombers in the area. Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed. In a year he collected reliable information on 1, 600 shoes. With this data, he and a colleague were able to test and improve a computer program designed to model ocean currents, and publish the findings of their study.
As the result of his work, Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean. He has even started an association of beachcombers and ocean experts, with 500 subscribers from West Africa to New Zealand. They have recorded all lost objects ranging from potatoes to golf gloves.
The underlined phrase swap meets in Paragraph 1 is closest in meaning to ______________.

Arriving in Sydney on his own from India, my husband ,Rashid, stayed in a hotel for a short time while looking for a house for me and our children.
During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.
He reported the case to the police and then sat there，lost and lonely in strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.
Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband’s name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can（垃圾桶）that had been left out on the footpath.
My husband rushed to their home to find a kind family holding all his papers and documents. Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half-written letter in the pile in which my husband had given his new telephone number to a friend.
That family not only restored the important documents to us that day but also restored our faith and trust in people. We still remember their kindness and often send a warm wish their way.
What does the underlined word “restored” in the last paragraph mean?
| A．Showed |
| B．Sent out |
| C．Delivered |
| D．Gave back |
Though I have traveled in hundreds of trains, few unusual things have ever happened to me. But one day in a train something did happen. I do not mean that I was hurt: no one was hurt.
I do my work in a hot country far away from England. Every September I go there to do my business, and every July I come back to England to have a rest. So every September I go to Paris and take a train from the great French city to Mendova, and at Mendova I catch my ship.
There is one very fast train from Paris to Mendova, and it suits me well. It goes as far as Endoran, but it stops at Mendova for a few minutes to let travelers get out or in. It is called The Flying Bluebird. It reaches Mendova at seven minutes past nine in the morning, and it is never late.
A ship leaves Mendova at half past eleven, and so you will understand that The Flying Bluebird suits me very well. I always travel by it, and I have nearly two and a half hours at Mendova to go from the station to the ship. That is more than enough time.
Well, one September night, I took my place in The Flying Bluebird as usual. The train leaves Paris at nine o’clock every night, and I was in my place soon after half past eight. There were three or four people there with me, but very soon a lot of others got into the train. When no more people could sit down, they began to stand up near us and also in the corridor(走廊). In a short time the corridor was full too, and it was impossible for any more travelers to get into the train.
I could see a lot of other people outside the corridor windows, but they could not get in, and the train left Paris without them. The man sitting next to me started to ask all kinds of questions: “Where do you work? How long does it take you to get there? Are you married? How many children do you have? How much money do they pay you every year? How much do you have in the bank? How much do you spend every month?”
He asked questions for about twenty minutes but I did not give him any clear answers, and at last he stopped and began to read the paper.
I usually sleep quite well in the train, but this time I slept only a little. There were too many people, and there were too many things: small bags, large bags, coats, hats, boxes, newspapers and food. As usual, we got angry about the window. Most people wanted it shut, and two of us wanted it open. But that always happens. It was shut all night, as usual.
When I awoke in the early morning I felt hot and dirty, and glad that the journey was reaching its end. At seven minutes past nine The Flying Bluebird stopped. We were at Mendova, and I stood up thankfully. I took my two suitcases, held one in each hand, and tried to move towards the door into the corridor. In order to get out of the train, I had to pass down the corridor to the door at the far end. There was no other way out.
I could not even into the corridor. There was a suitcase on the floor by my feet, and three men were standing in my way. I felt a touch of fear. I had to get out, you see; I had to catch my ship, which left at half past eleven. And the train did not stop again until it reached Endoran, two hundred miles away.
“I must get out!” I cried. Everyone there understood me, but no one could move.
At last I was able to put one foot over the suitcase on the floor, and I nearly reached the door into the corridor. But then, very slowly, the train began to move. It was taking me away!
“Stop!” I cried. “I want to get out!” But no one outside the train could hear me, and the people inside did not care much. The train moved a little faster. What could I do? I was not even in the corridor.
Fear made me think quickly. In front of my eyes, just, above the door, was a notice that told everyone how to stop the train. I had to pull an iron thing near the notice. I did not waste time. I pulled it.
Well, a noise started above our heads. That was to show everyone that there was something wrong. It was not a small sound. Possibly the men in my ship two miles away could hear it. Then the train stopped.
No one likes to stop a train if there is no need. But I had to catch my ship. That was the only thought in my mind: to get out and catch my ship.What do we know about the author and the man sitting next to him?

If you get into the forest with your friends, stay with them always. If you don’t, you may get lost. If you really get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you by staying in one place.
There is another way to help your friends or other nearby people to find you. Give them a signal (信号) by shouting or whistling (吹口哨) three times. Any signal given three times is a call for help.
Keep up shouting or whistling always three times together. When people hear you, they will know that you are not just making noise for fun. They will let you know that they have heard your signal. They give you two shouts, two whistles, or two gun-shots (枪声). When someone gives you a signal, it is an answer to a call for help.
If you don’t think that you will get help before night comes, try to make a little house---cover up to the holes with branches (树枝) with lots of leaves. Make yourself a soft bed with leaves and grass.
What should you do if you get hungry or need drinking water? You would have to leave your little house to look for a river. Don’t just walk away. Pick off small branches and drop them as you walk so that you can find your way back. The most important thing to do when you are lost is—stay in one place.
If you are lost in the forest, you should _______.

Teenagers are often a difficult group. With all those hormones（荷尔蒙） flooding their bodies, they can be moody, unpredictable, and tend to make uncertain choices. But however confusing their teenage years are, kids can still be generally happy, depending on their lifestyle choices. According to a new research by British scientists, teens who don’t smoke, drink only moderately or not at all, and who don’t eat much junk food are likely to be happier than other teens.
The study looked at 40,000 British families and came up with some interesting findings. For example, kids who never drank alcohol were up to six times more likely to report higher levels of happiness than kids who drank. And teens who smoked were five times less likely to rate high on happiness charts compared to kids who don’t smoke. Same goes for diet and physical activity. The more fruits and vegetables kids eat, and the more hours they spend playing sports, the happier they are.
Now, of course this doesn’t mean that not smoking or drinking, and playing sports guarantees happiness. It could be that kids who have happy character tend to be more active and less addicted to drinking or smoking. And it could equally be the case that kids who are unhappy are more related to drinking and smoking and eating junk food.
Other studies have shown that exercise is a proven way to treat anxiety and depression. Future studies may support the idea that other healthful behaviors, including refraining(克制) from smoking, drinking, and eating too much junk, can avoid sadness and increase happiness, too.What can we learn from the text?
| A．Not smoking or drinking guarantees happiness. |
| B．Teens with flooding hormones can not be happy. |
| C．Playing sports can decrease teen’s unhappiness. |
| D．Unhappiness can certainly result in smoking and drinking. |
Which of the following might help teens quit anxiety?
| A．Smoking and drinking. |
| B．Taking exercise. |
| C．Eating junk food. |
| D．Going on a diet. |
