There are many differences in eating habits among China and western countries. Firstly, Chinese people ate rice, noodles, vegetables and meat when western people prefer bread, milk, salad and steak. Secondly, westerners used to eating with a knife and a fork, but the Chinese eat with chopstick. Thirdly westerners usually eat quiet instead of making a loud noise during meals. They think it is very much impolite. However, this is common for the Chinese to talk with family members and friends while have dinner. Anyway, it is considering bad manners in both China and western countries to talk with our mouths full.

【答案】among → between

ate → eat

when → while

used前加are

chopstick → chopsticks

quiet → quietly

this → it

删除very后的much

have → having

considering → considered

【解析】

这是一篇说明文。文章主要介绍了中西方饮食文化的差异。

1. 考查介词。在两者之间应用介词between,故将among改为between

2. 考查时态。本文陈述一般事实,应用一般现在时,故将ate改为eat

3. 考查连词。句意:中国人吃大米、面、蔬菜和肉食,而西方人更喜欢面包、牛奶、沙拉和牛排。结合句意可知,此处意为“然而”,表前后的对比,其表示是while,故将when改为while

4. 考查短语。句意:西方人习惯用刀叉来吃,而中国人用筷子。结合句意可知,此处考查短语be used to doing sth.“习惯于做某事”,主语westerner是复数,故在used前加are

5. 考查名词的数。结合常识可知,筷子是成对出现的,应用复数形式,故将chopstick改为chopsticks

6. 考查副词。此处应用副词修饰动词eat,故将quiet改为quietly

7. 考查代词。分析句子结构可知,此处考查固定句型it is + adj. + for sb. to do sth.(对于某人来说做某事是怎么样的)it是形式主语,to do 是真正的主语,故将this改为it

8. 考查副词。much不能修饰形容词的原级,故删除very后的much

9. 考查非谓语动词。此处是状语从句的省略,while引导时间状语从句的完整句子为while the Chinese are having dinner, 因为和主句的主语一致都是Chinese,且有be动词,故省略了从句中的Chineseare,故将have改为having

10. 考查非谓语动词。句中it是形式主语,真正的主语是to talk with our mouths full,它和consider之间是被动关系,应用被动语态,此处应使用过去分词,故将considering改为considered

【题目】 Imagine your clothing could release enough heat to keep you warm and cozy, allowing you to stay comfortable in a cooler room. Or, picture a car windshield that stores the sun's energy and then releases it as heat to make the ice on the windshield disappear.

According to a team of researchers at MIT, both cases may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.

Solar energy is only available about half the time we need it — during daylight. For the sun to become a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding, by MlI professor Jeffrey Grossman, Postdoc David Zhitomirsky and graduate student Eugene Cho, could provide a highly efficient method for storing the sun's energy through a chemical reaction and releasing it later as heat.

The key to enabling long-term, stable storage of solar heat, the team said, is to store it in the form of a chemical change rather than storing the heat itself. But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. When exposed to sunlight, the molecules can stay that way for long periods Then, when triggered (触发)by a very specific temperature or something else, the molecules return to their original shape , giving off heat in the process.

Such chemically-based storage materials, known as Solar Thermal Fuels(STF), have been developed before. But those earlier efforts were designed to be used in liquid solutions and not able to make durable (耐用的) solid-state films. The new approach is the first based on a solid-state material, in this case a polymer, and the first based on inexpensive materials and widespread production technology.

1What is the main purpose of Paragraph 1?

A.To show the main idea of the passage.

B.To practice readers' imagination.

C.To interest readers in the passage.

D.To introduce a new kind of material.

2According to the passage, what can the polymer film do?

A.It can be made into window glass.

B.It can make necessary electricity.

C.It can store energy and release sunshine.

D.It can absorb sunshine and give off heat.

3According to the passage, what is STF based on?

A.The chemical reaction.

B.The movement of heat.

C.The form of electricity.

D.The physical reaction.

4What is the advantage of the molecular configuration?

A.It is less expensive.

B.It is very powerful.

C.It is easily available.

D.It is less changeable.

Agricultural experts say crop diversity is important to feed the1(increase) population of our planet. They say having a large variety of plants also2(help) to protect against possible crop diseases and future crises. But many experts say the number has decreased sharply during the past century.

One of the world's 3(large) seed conservation projects has predicted further losses. The Millennium Seed Bank Partnership is warning that up to one hundred thousand plant species could 4 (permanent) disappear. The rich collection of genes5 decide their qualities would disappear with them.

Many experts blame climate change and loss of habitat, normal growth area, for damaging plant life. They say human6(activity) and poorly planned, overly heavy use of land also are responsible. Modern business farming is responsible7loss of farmers' traditional crop varieties. The "Green Revolution" of the twentieth century changed agriculture. Some experts say the use of modern commercial farming methods saved millions of people from8(starve). Farmers planted, watered, and fertilized their crops with the help of machines. They treated their fields with chemicals9(control) diseases and insects. Harvests grew larger and higher quality,10 another result was that some traditional crops were lost. Damage to the environment over the past century makes people believe that crop diversity also suffered.
