Why do you think people who live in some hot countries eat very spicy(辛辣的)food? Is it because the spices make the food taste better? Is it just because their parents and grandparents and great-grandparents liked hot food,or is there some connection between spices and healthy food?
Researchers from Cornell University think that it is because spice plants have some important chemicals(化學物質).These chemicals can kill bacteria(細菌)which spoil food.
“Most common spices can kill 75 to 100 percent of the bacteria in food,”explains one of the scientists.The bacteria grow more easily and spoil food more quickly at higher temperatures.For this reason,it is more difficult to keep food from spoiling in hot climates,
Do you like your food spicy? Your answer probably tells something about the country you come from.If you like spicy food,it is possible that hundreds of years ago,when there were no fridges,people in your country started using spices to keep the food from spoiling.The traditional spicy dishes helped those people to live longer,healthier lives.Today,in a time of fridges,the spices just make the food taste good.
小題1:The chemicals in spices keep food from spoiling by_________.
A.making food taste better
B.making food hotter
C.killing bacteria in food
D.preventing bacteria getting into food
小題2:Food goes bad more quickly in hot climates because_______.
A.high temperature makes more bacteria
B.high temperature helps bacteria grow faster
C.bacteria get used to hot food
D.bacteria spoil food only at high temperature
小題3:According to the passage,spices are useful in an the following things except_______.
A.replacing fridges
B.helping you to live longer
C.helping to keep you healthier
D.making your food taste better

小題1:C
小題1:B
小題1:A

文章講的是為什么人們喜歡吃辛辣的食物的原因。
1. C 細節(jié)考理題,從These chemicals can kill bacteria(細菌)which spoil food可知它們可以殺死食物中的細菌,故選C。
2. B 從The bacteria grow more easily and spoil food more quickly at higher temperatures可知氣溫越高細菌越容易越快生長,從而導致食物的變質,選B。
3. A 此題是對全文內(nèi)容的分析。從文章最后一段可知B,C,D正確,有段時間把辛辣食物放裝箱里只是讓食物更好吃,更沒有說能代替冰箱,故D說法片面不正確,選A。

What do people do with their old, out-of-date but still useful computers? Most people don’t know what to do with them. Many old computers are put away in homes. Many more are simply thrown out with the rubbish.  
Some companies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products. Dell, Hewlett-Packard and other companies now also take back some old computers.  
In some countries, laws are being passed, too. Computer companies will have to collect and recycle their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade(升級).  
Yet while many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations are working to solve this problem. They collect and repair old computers. Some also teach others how to repair computers.  
The computers then go to schools, charities and people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish into someone else’s useful things—and cut down on waste, too.

Every morning, the newspaper chief editor(主編) holds a meeting with the reporters. They discuss the main events(事件) of the day. Reporters are then sent to cover the events.
As soon as the reporters know what to write about, they get down to work. They telephone people and fix a time for a face-to-face interview with them. Sometimes they do telephone interviews. Checking information is very important. They go to the newspaper’s own library to look up any information that they need. This is called “doing one’s homework”.
At the same time, the picture editor decides which photographs will be used for the next day’s paper. All the people who work on a newspaper must be able to work fast. Reporters have to stop working on one story and start working at once on the important new one. They must find out the new information as quickly as possible. Later in the day, everything is put together at the news desk. Reporters return, type their stories into the computer and hand them to the editor.
The chief editor decides which will be the most important story on the front page. Sometimes this will have to be changed if something more important happens late in the day. Other editors read the stories which the reporters have written and make any necessary changes.
Finally, there is no more time left for adding new stories, and the time for printing(印刷) the newspaper has come. This is done on fast-moving printing machines. The newspapers are then delivered(發(fā)送) by truck, plane or rail. Speed is important. People want to buy the latest newspaper; nobody wants to buy yesterday’s.

“If you want to see a thing well, reach out and touch it!”
That may seem a strange thing to say. But touching things can help you to see them better. Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can tell how heavy the glass it. When you feel all these about the ball, you really see it.
With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pockets. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what “Don’t touch!” means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it.
The bottom of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.
There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them.
Most museums are just for looking. But today some museums have things for visitors to touch. Their signs say, “Do touch!” there you can feel everything on show.

In today’s world many people seem to be hungry for money. Some of them even have lost their lives for it. Money does have a great effect on the poor, but if a person has a rich life, a lot more money doesn’t mean more happiness.
If money were everything, all millionaires would have true love, real friendship, health and a long life. However, this is not always true.
Nothing else is more pleasant than the three words “I love you”, but can love be bought? I’m afraid not . Love means “give”, not “take”. Health and a long life are precious things for every person. Well, can health and a long life be bought with money? The answer is “No”. Of all the people who live longest in the world, few of them are millionaires. Real friendship can’t be bought, either.
In a word, where money is worshiped, money can cause brothers to quarrel, lovers to hate, strangers to fight and so on, No matter how much money you have, it is still not enough to make you a happy person if you have no one to laugh with and no one to cry for.

On a cold December morning, my mother and I were walking home from pizza store. We were served
warmly and equipped with the video we had been trying      . I was feeling a little tired      I was carrying our shopping bags of snacks and the video.
They were so     that I decided to throw away some of them. So I started to walk towards the dustbin when I noticed a poor man stepping out of the restaurant in front of us. He held a paper bag with his dirty hand. He headed for another nearby dustbin and started looking      something.
I suddenly felt very upset. I know this man would take all he could get, so I walked up to him and handed the drink and some snacks to him. The man, with lines on his face and wrinkles(皺紋) on his forehead, looked up in     and took what I gave him.
A huge smile spread across his face and this made     feel indescribable satisfaction(滿意). I felt like I couldn’t be happier with myself, but then he said, “Wow, first someone gives me this sandwich, then this drink, and now some tasty food, this is my daughter’s      day!”
He thanked me     and started off on his bike. I even heard him whistling(吹哨) a song as he
    away.
I now understand what is meant by the saying “Giving is getting”. Everyone in the world needs help, everyone can      help and everyone will be helped by something kind.
The image(圖像) of that man’s happiness caused by my small gift appears in my mind every time I have the chance to do something nice.
