【题目】Harvard researchers have created a tough, low-cost, biodegradable (可生物降解的) material inspired by insects' hard outer shells. The material's inventors say it has a number of possible uses and someday could provide a more environmentally friendly alternative to plastic. The material, made from shrimp (奸) shells and proteins produced from silk, is called "shrilk. "It is thin, clear, flexible and strong.

A major benefit of the material is its biodegradability. Plastic's toughness and flexibility represented a revolution in materials science during the 1950s and ’ 60s. Decades later, however, plastic's very durability (耐用性) is raising questions about how appropriate it is for one-time products such as plastic bags, or short-lived consumer goods, used in the home for a few years and then cast into a landfill where they will degrade for centuries. What is the point of making something that lasts 1, 000 years?

Shrilk not only will degrade in a landfill, but its basic components are used as fertilizer (肥料), and so will enrich the soil.

Shrilk has great potential, the inventors said. Materials from which it is made are plentiful in nature, found in everything ranging from shrimp shells, insect bodies to living plants. That makes shrilk low cost, and its mass production possible should it be used for products demanding a lot of material.

Work on shrilk is continuing in the lab. The inventors said the material becomes flexible when wet, so they're exploring ways to use it in wet environments. They're also developing simpler production processes, which could be used for non-medical products, like for computer cases and other products inside the home. They're even exploring combining it with other materials, like carbon fibers, to give it new properties.

【1】Paragraph 1 of the passage is mainly about shrilk's __________.

A. remarkable design B. interesting name

C. major features D. basic elements

【2】What has become a concern about plastic?

A. Using it properly.

B. Producing it cheaply.

C. Developing its properties quickly.

D. Evaluating its contributions fairly.

【3】According to the inventors, shrilk has great potential partly because __________.

A. it can help plastic degrade

B. it can be found in living things

C. its mass production has been realized

D. its raw materials are abundant in nature

【4】What are the inventors doing in the lab?

A. Replacing carbon fibers with shrilk.

B. Testing shrilk's use in wet conditions.

C. Making shrilk out of used household goods.

D. Improving shrilk's flexibility for medical purposes.

【5】Which of the following can be the best title for the passage?

A. Recent Progress in Environmental Protection

B. Benefits of Insects in Scientific Research

C. The Harm of One-time Products

D. A Possible Alternative to Plastic

【题目】There is an English saying that "Laughter is the best medicine. "Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter can really improve people's health.

Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works on several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.

Other tests have shown that laughter appears to be able to reduce the effects of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated (, 忍耐) the pain for the longest time was the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.

As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

【1】According to the passage, which of the following statements is WRONG?

A. Laughter is good for health.

B. Laughter can make you become old quickly.

C. Laughter helps to reduce pain.

D. Laughter, just like physical exercise, is good for our body.

【2】The underlined word "diminishes" in the third paragraph means" __________ "

A. delays B. prevents

C. increases D. reduces

【3】 Why do some doctors hold laughter clinics?

A. Because they want to earn more money.

B. Because they think they will help the patients recover from illnesses.

C. Because they want to improve their patients' condition.

D. Because they want their patients to practice how to laugh.

【4】According to the author, we should __________.

A. laugh as much as possible

B. watch more funny films

C. smile all the time

D. spend more time in laughter clinics

【5】What would be the best title for this passage?

A. Both laughter and physical exercise are good for health

B. Laughter clinics help patients improve their condition

C. Laughter can reduce the effects of pain

D. Laughter is the best medicine
