If lawmakers do not do something soon to prohibit spam, the problem will certainly get much worse. Computer programs allow spammers to spend hundreds of millions of e-mails almost instantly. As more and more advertisers turn to spam to sell their products, individual e-mail boxes are often flooded with spam e-mails. Would people continue to use e-mail if they had to deal with an annoying amount of spam each time?
This problem is troubling for individuals and companies as well. Many spam emails contain computer viruses that can shut down the entire network of a company. Companies rely on e-mail on for their employees to communicate with each other. Spam frequently causes failures in their local communications networks, and their employees are thus unable to communicate effectively. Such a situation results in a loss of productivity and requires companies to repeatedly repair their networks. These computer problems raise production costs of companies, which are, in the end, passed on to the consumer.
For these reasons, I believe that lawmakers need to legislate (立法) against spam. Spammers should be fined, and perhaps sent to prison if they continue to disturb people. E-mail is a tool which helps people all over the world to communicate conveniently, but spam is destroying this convenience.

小题2:D 细节题。根据第二段2,3行As more and more advertisers turn to spam to sell their products, individual e-mail boxes are often flooded with spam e-mails.说明很多公司连用垃圾邮件来宣传产品,故D正确。
小题3:D 细节题。根据第三段最后一句These computer problems raise production costs of companies, which are, in the end, passed on to the consumer.说明最后这些问题都转嫁到了消费者身上,故D正确。
小题4:C 主旨大意题。本文叙述了垃圾邮件的危害,是为了呼吁立法部门设立相关法律,故C正确,是为了说服政府。

We had just been to the gym and stopped to 31 at the restaurant.
“No,” I replied, “you don’t need a piece of cake.”
My son 32 15 in a few days. He 33 over 6 feet tall. He is very slim and athletic in shape. It was not always that way. My wife wrote a book about the challenge and 34 of getting him fit. He now takes it 35 and looks as he’s never been overweight in his life.
He had a full plate of 36 and tofu. He didn’t need a piece of cake. Besides, everything in the restaurant is quite 37 . Our dinners could have 38 a family of seven at a fast food restaurant. That cake probably cost $5.
He was 39 as he looked at the delicious cakes. I had forgotten that I had walked over to the cake shelf while he was 40 his food from the buffet (自助餐).
I looked at my 41 . There sitting on the edge was a piece of 42 . I looked at it wondering but also knowing how it got there. “We will divide it,” I said.
A few days later my oldest son was with me again. We stopped at a 43 . He ordered a sandwich. I then 44 two sandwiches. He immediately barked, “Can I have two?” He wanted exactly what Daddy had.
Your kids are very likely to put on their plates, exactly what you have on yours, and I think this applies to more than food. Keep your 45 plate with only what you want your kinds to have.

The Hoffmans have been growing food and flowers for twenty-five years. For almost ten of those years, Mr. Hoffman has been experimenting and working with shade (阴凉) plantings. He says, “The bottom line here is that most plants will produce more in full sun. But if you do not have full sun, there are other choices.”
For example, he grows tomatoes near oak trees. Oak trees can produce a lot of shade. But Mr. Hoffman says his tomato plants grow as long as they get five hours’ direct sunshine a day, especially morning sun. Not only does this go against the traditional advice that tomatoes need six, eight, even twelve hours’ full sun a day. It also shows how plants and tree roots can share nutrients and water.
Mr. Hoffman says plants with wider leaves seem to do better in shady environments. He also found that his potatoes did better partly in shade than in full sun.
Moving them out of the sun helped control an insect problem. Mr. Hoffman does not use pesticide (农药). Instead, he planted the potatoes in the shade, especially on the east side of the tree. The potatoes get morning sun, but they are shaded during the hottest part of the day. Some insects dislike shade, and the hottest part day is when they do the worst of their damage.
Time of day, sun intensity (强度), shadows from trees, walls and buildings all influence how much sunlight falls on plants. And people interested in shade planting should also remember something else. The term “shade” can describe different amounts of darkness. It can even mean different things in different parts of the world.
小题1:How many hours of sunshine are enough to keep tomato plants growing in Hoffman’s garden?
A.five hours a day | B.Six hours a day |
C.Eight hours a day | D.Twelve hours a day |
A.plants with wider leaves produce more in full sun. |
B.as a matter of fact, plants don’t need to grow in full sun. |
C.the more sunshine plants get, the more they will produce |
D.plants with wider leaves grow better in shadows |
A.length of day time |
B.brightness of the sun |
C.changes of the season |
D.shadows |
A.Curious | B.Experienced | C.Easy-going | D.Funny |
A.environment | B.travelling | C.agriculture | D.lifestyle |
What happens after an earthquake? We sent in rescue dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal (信号). This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University,New York, says, “‘Robots ’noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity(电)!
The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn’t get to and a rat would get out of it if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).
小题1:In the world earthquake capitals, rats will become man’s best friends because they can .
A.take the place of man’s rescue jobs |
B.find the position of people alive who are trapped in buildings |
C.serve as food for people alive who are trapped in buildings. |

D.rats can see in the dark and smaller than robots |
A.they are more fantastic than other animals |
B.they are less expensive to train than dogs |
C.they don’t need electricity |
D.they are small and can get into small places |
A.at present rats have taken the place of dogs in searching for people |
B.the “rat project” has been completed |
C.people are now happy to see a rat in a building |
D.now people still use dogs and robots in performing rescues |
ESP stands for Extrasensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.
Here"s an example. A woman was ironing clothes. Suddenly she screamed, "My father is dead! I saw him sitting in the chair!" Just then, a telegram came. The woman"s father died of a heart attack. He died sitting in a chair.
There are thousands of stories like this one on record. Scientists are studying them to find out what"s behind these strange mental messages. Here"s another example—one of hundreds of dreams that have come true.
A man dreamed he was walking along a road when a horse and carriage came by. The driver said, "There"s room for one more." The man felt the driver seemed dead, so he ran away. The next day, when the man was getting on a crowded bus, the bus driver said, "There"s room for one more."
Then the man saw that the driver"s face was the same face he had seen in the dream. He wouldn"t get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!
Some people say stories like these are coincidences. Others, including some scientists, say that ESP is real. From studies of ESP, we may someday learn more about the human mind.
小题1:According to the passage, the author believes that the sixth sense is ________.
A.in existence | B.imaginative | C.not real | D.impossible |
A.about events before they happen |
B.about events after they happen |
C.about events that are happening some distance away |
D.A and C |
A.things that may not happen |
B.things that happen in a dream |
C.things that must happen |
D.things that happen by accident |
A.the human dream | B.the sixth sense |
C.the human mind | D.a crowded bus |
The honey guide does not actually like honey, but it does like the wax in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees" nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey and the wax always falls to the ground, and this is when the honey guide takes its share.
Scientists do not know why the honey guide likes eating the wax, but it is very determined(坚定的) in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.
小题1:Why is it difficult to find a wild bees" nest?
A.It"s small in size. | B.It"s hidden in trees. |
C.It"s covered with wax. | D.It"s hard to recognize. |
A.A bee. | B.A bird. | C.A honey seeker. | D.A beekeeper. |
A.it gets its food | B.it goes to church |
C.it sings in the forest | D.it reaches into bees" nests |
