Living in a modern society has its advantages and disadvantages. One disadvantage is that you often have to live closer to other people than you would like to. Sometimes, your neighbors make noise that you are not comfortable with.

The best way to solve this problem is to talk with your neighbor first. You should be very polite and ask your neighbor if he knows how thin the walls of your homes are. This way doesn’t criticize(批评)his behavior; it simply points out that he may not realize how far his sound travels. Tell him that you know that sometimes you make noise as well, but that you do your best to keep it down. Often this will solve the problem right away, but sometimes the neighbor may become angry.

If your neighbor becomes angry with you, there are some more steps you can take. You might write a letter to the neighborhood committee. Make sure you write down the source of the noise and the time in the letter. They will review the situation and decide whether your neighbor is out of line. Some noise is considered to be reasonable, even if it bothers you. So you may prepare a good pair of earplugs(耳塞).

Even if your neighbor makes too much noise, you don’t have to live your life in discomfort. It’s always a good idea to be friendly with your neighbors. You may clean the rubbish in front of his door. He’s sure to appreciate behavior like this and be more open to your suggestions about noise level.

1. What is the first step to deal with the noisy neighbor?

A. To buy a good pair of earplugs.

B. To offer suggestions to the neighbor.

C. To ask the neighborhood committee for help.

D. To tell the neighbor how bad his behavior is.

2.The underlined word “reasonable” in the third paragraph probably means“　　”.

A. terrible　　    B. loud　    　C. proper　    　D. unpleasant

A. How to punish your noisy neighbor.

B. Where and when the noise appears.

China Science Daily announced Thursday that it has used software to automatically generate news stories about the latest discoveries from the world’s leading science journals. The robot science reporter, called “Xiaoke”, was co-created by the newspaper and researchers from Peking University in about half a year.

It is the latest case of Chinese news organizations using computer technology to create content. According to its inventors, Xiaoke has generated over 200 stories based on the English abstract of papers published in journals such as Science, Nature, Cell and the New England Journal of Medicine.

Before publication, the automatically generated articles will go through a review process. A group of scientists and the newspaper’s editors will check the content or give supplementary (补充的) information.

Zhang Mingwei, head of the program and vice editor-in-chief of the newspaper, said inventors would make Xiaoke a “cross-linguistic (跨语言的) academic secretary” to help Chinese scientists overcome language barriers and have easy and quick access to the latest scientific advances in English-language publication. Lead researcher Wan Xiaojun, of Peking University in charge of the system’s design and technology, stressed that the content generation tool could do far more than translation. According to Wan, Xiaoke is good at selecting complex words and sentences, which can help turn articles full of confusing technical terms into easy and readable news reports.

The readers of the robot reporter is not limited to professionals but also includes the general public. Science reporting is important in spreading information about discoveries and in popularizing knowledge to people.

1.What can we learn about “Xiaoke”?

A.It is a professional translator.

B.It has the most advanced AI.

C.It can make up fiction stories.

D.It generates science news reports.

2.What do people need to do to improve Xiaoke’s work?

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.

Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma(黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.

Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence(发生率)faster than any other cancer in the United States.

But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.

The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer—people with fair skin and freckles(雀斑), for example—are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.

The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.

1.The underlined word “flaws” in the 2nd paragraph most probably means 　　　　 .

A. evidences        B. facts        C. faults        　　 D. failures

2.People with fair skin and freckles 　　　　　 .

A. seldom use sunscreen            　　　　

B. are more in danger of skin cancer

C. can be free from the harm of the sun    　

D. often expose themselves to the sun

3.We can learn from the passage that 　　　　　 .

A. sunscreen users get skin cancer more often

B. the volunteers have proved the effect of sunscreen

C. the new study was based on the experiences of volunteers

D. the number of skin cancer patients is increasing in America

4.Which of the following can be the best title for this passage?

A. Sunscreen to Prevent Skin Cancer    　　

B. Sunscreen to Increase Skin Cancer

C. Skin Cancer Caused by Sunscreen    　　

D. Skin Cancer Caused by Freckles

高三英语阅读理解中等难度题查看答案及解析

You may use banknotes every day. But did you know that there is a lot of science behind the money? 1.

Australia was the first country to use polymer(聚合物）banknotes in 1988. 2.

They can stop water from making them wet. They are also cleaner because bacteria don’t grow easily on them.

Now, the Australians have improved their banknotes again by creating a new 5-dollar note. The new one has a clear window in the middle in which there are pictures of an Australian bird and a building. 3.

Tilt (倾斜）the note a little and you will see the bird flapping its wings as if trying to fly away. Turn the note from side to side and you will notice the building come to life and spin. While these features are impressive and entertaining, that was not the reason why the Australian Government spent ten years perfecting them. Their primary purpose was to make it impossible to fake a banknote.

4. The new $ 5 bill now has a raised bump alongside the two long edges, enabling the blind or those with limited vision, to quickly determine its value.

The Australian government will give the new 10-dollar note the same features in a year’s time. 5.

A. Note makers still have a long way to go.

B. Other notes will have them in the future.

C. The magic of the new features lies in them.

D. They have many advantages over paper notes.

E. The new Australian 5-dollar note is a good example.

F. The new note is also the first touchable Australian banknote.

G. Their material and pattern set them apart from ordinary banknotes.

It has been found that less than one shopper in five makes a complete shopping list before going to the store. The reason for this is that seven out of ten of today’s purchases(购买) are decided in the store, where the shoppers tend toward impulse(冲动) buying. Buying groceries on impulse had risen for the past forty years, and this rise has coincided(巧合) with the growth of self-service shopping. However, in grocery stores where clerks wait on customers there is much less impulse buying. It is hard for people to buy on impulse if they have to address a clerk.

Psychologists have joined forces with merchandising(商品) experts. It is their job to persuade people to buy products which they may not need or even want until they see them attractively presented. It was discovered by the psychologists that shoppers want help in their purchases. Having so many choices confuses them, and they prefer the package that attracts them. Therefore, it is now more usual for food packers to pay attention to their package design. Attraction depends heavily on the position of the product on the shelf, however. Thus, persuading the shopper to buy is easier if the product is located at eye-level.

1.According to the information in the first paragraph, ______ make a complete list.

2.The reason for the above mentioned phenomenon is that _______.

3.In grocery stores where customers are served there is less impulse shopping. This may be because ________.

4.Shoppers tend to buy the products put on _______.

5.Which of the following might be the best title for this passage?
