【題目】Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.

Space is a dangerous place, not only because of meteors (流星) but also because of rays from the sun and other stars. The atmosphere again acts 【1】 our protective blanket on earth. Light gets through, and this is essential for plants 【2】(make) the food which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun 【3】 (screen) off. As soon as men leave the atmosphere, they are exposed to this radiation but their spacesuit or the walls of their spacecraft,【4】 they are inside, do prevent a lot of radiation damage.

Radiation is 【5】(great) known danger to explorers in space. The unit of radiation is called "rem". Scientists have reason to think that a man can put up with far more than 0.1 rem without 【6】(damage); the figure of 60 rems has been agreed on. The trouble is 【7】 it is extremely difficult to be sure about radiation damage - a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered 【8】 the birth of deformed children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys, the Apollo crew accumulated (積累) a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply don't know yet 【9】 men are going to get on when they spent weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage 【10】(do) by radiation, but no really effective ones have been found so far.

【題目】 Hetty Robinson learnt all about money when very young. As a child, she read the financial pages of the newspaper to her rich father. Her father died when Hetty was 30, and she inherited $1 million. When she herself died in 1916, she left almost $100 million to her two children.

Hetty made her money on the New York stock exchange. She was a financial genius. She made money so easily that people called her the Witch of Wall Street. But although she was one of the richest women in the world, she counted every cent and spent as little as possible. She didn’t own a house, because she didn’t want to pay property taxes. So she and her children lived in cheap hotels.

She spent almost nothing on clothes, and always wore the same long black dress. She washed it herself, but to save soap she only washed the bottom of the dress, where it touched the ground. Other people had their own offices, but Hetty used a desk in the bank where she kept her money, because it didn’t cost anything. She sat in the bank and ate her sandwiches while she bought and sold stocks and shares. If the bank complained, she just moved all her money to another bank.

Hetty’s family paid the price for her meanness. When she was 33 she married a millionaire, Edward Green, and they had two children. But Green lost all his money, so she left him. When her son, Ned, injured his knee, Hetty didn’t want to pay for a doctor, so she took him to a free hospital for poor people. Unfortunately the doctor knew Hetty was rich and he asked for money. Hetty refused and took the boy away. His leg got worse and two years later doctors removed it.

But eventually Ned got his revenge. At the age of 81 Hetty had an argument with a shop assistant about the price of a bottle of milk. She became so angry that she had a heart attack and died. So Hetty’s meanness finally killed her. Ned inherited half his mother’s fortune, and he spent it all on parties, holidays and expensive jewellery.

【1】What fact can be learned about Hetty Robinson from the passage?

A.She came from a poor family.B.She worked for a bank.

C.She was nice to her son.D.She died from extreme anger.

【2】Hetty Robinson was called the Witch of Wall Street mainly because ________.

A.she was fond of reading financial pages of the newspaper

B.she made a huge fortune easily through stocks and shares

C.she liked wearing the same long black dress every day

D.she turned out to be the richest woman in New York

【3】Which of the following best describes Hetty Robinson?

A.Talented but not generous.B.Wealthy and kind.

C.Aggressive but not diligent.D.Curious and lucky.

【題目】短文改錯

Dear Sir/Madam,

I am writing to complain to a sweater, a jacket and a pair of shoes what I bought from your online shop last month. Fortunately, when the order arrived I realized that the sweater had the hole in it. Also when I tried on the jacket I noticed that it had a button missed and was not the size I have ordered. And the style of the shoes were not what I had asked for. I am returning to the clothing. I would appreciate if I could get a fully refund. I am looking forward to your reply.

【題目】 Humans and elephants don’t always get along. In Africa and Asia, elephants damage infrastructure (基礎(chǔ)設(shè)施), farmers’ crops, and natural habitat critical for other species. If an elephant becomes a problem, humans may kill it. So local people and conservationists are trying to find better ways to keep elephants away from sensitive places. Now, researchers think they have a good tool to stop elephants: honeybee pheromones (信息素).

“Elephants hate being stung (刺) in the trunk, so it’s an extremely sensitive organ. Imagine being stung in your nose by a bee, and multiply that a few thousand times.” said Mark Wright, a professor of entomology at the University of Hawaii at Manoa.

Kenyan farmers have long known that if they hang live beehives around their farms, they will repel elephants. “The problem is logistical, how do you manage hundreds of thousands of hives, if you have a huge area to protect? And then the idea came up to look at the alarm pheromones, which are chemicals that the bee release to launch an attack on something that’s damaging the hive.” Because elephants have a highly developed sense of smell, Wright and his team thought they might be able to use the bees’ alarm signal to affect elephant behavior.

So the researchers tested out a synthetic blend (合成混合物) of chemicals that imitates honeybees’ alarm pheromones. In Greater Kruger National Park in South Africa, the team hung white socks treated with the synthetic mixture as well as untreated control socks around an elephant watering hole, and then observed the animals’ behavior. “Elephants are really curious organisms, they’ll walk along and see something like a sock hanging on a branch in the environment, and they’ll inspect it. And if it’s not treated with the alarm pheromones, they’ll pick it up, throw it around, try to taste it, things like that. And in the case of the treated ones, we found that they would show immediate signs of unease or uncertainty, and they’d eventually back off from them. Very seldom would they go to pick them up and play with them.” The study is in the journal Current Biology.

【1】What will the researchers do to prevent elephants from damaging human’s habitat?

A.Kill them.B.Scare them away.

C.Apply honeybee pheromones.D.Rebuild a new ecosystem.

【2】What does Mr. Wright think of Kenyan farmers’ method if it’s applied to a huge area?

A.Scientific.B.Flexible.C.Awesome.D.Impractical.

【3】Why did the researcher conduct the study?

A.To confirm what they thought.

B.To attract the elephants’ attention.

C.To preserve the elephants’ habitat.

D.To test out honeybee’s alarm pheromones.

【4】What’s the main idea of the text?

A.Elephants and humans don’t get along well.

B.Honeybee pheromones can keep elephants away.

C.Elephants have a highly developed sense of smell.

D.Honeybees release pheromones to launch attacks.
