本文是一篇與笑有關(guān)的說明文，介紹了笑與健康的關(guān)系，建議我們要多笑一些。

【1】考查時態(tài)語態(tài)。本文敘述與笑有關(guān)的話題，通篇使用一般現(xiàn)在時，且laugher與use構(gòu)成被動關(guān)系，所以使用一般現(xiàn)在的被動語態(tài)is used。

【2】考查形容詞。橫線后有名詞effects，可知橫線上應(yīng)該使用形容詞beneficial做定語修飾名詞effects，表示笑在不同方面對人體有很多有益的好處。

【3】考查主謂一致。本句謂語動詞have說明主語應(yīng)該用復(fù)數(shù)形式，而名詞study的復(fù)數(shù)形式是studies。句意說明笑可以增強(qiáng)免疫系統(tǒng)。

【4】考查固定搭配。短語be likely to do sth可能做某事；句意：這種細(xì)胞讓我們不太困難感染咳嗽或感冒。使用本句使用不定式to catch…。

【5】考查定語從句。本題定語從句的先行詞是the air，關(guān)系代詞that/which指代先行詞the air在句中做介詞in的賓語。

【6】考查固定搭配。形容詞短語be similar to…與…類似；

【7】考查副詞。在英語中，副詞通常做狀語修飾形容詞、副詞或者動詞，本句中副詞especially做副詞修飾形容詞helpful。

【8】考查形容詞。本句中使用形容詞stronger與后句轉(zhuǎn)中better構(gòu)成并列關(guān)系。

【9】考查動名詞。本句中的like是介詞，意為“像…一樣”；介詞的后面要接名詞、代詞或動名詞做賓語。句意：經(jīng)常笑就像是讓你的心臟得到鍛煉一樣。

【10】考查固定搭配。短語as…as…與…一樣；本句表示每天笑15分鐘相當(dāng)于每周三次每次笑半小時。

本文考查了時態(tài)語態(tài)，動詞的時態(tài)、語態(tài)是每年的必考點(diǎn)，也是歷年高考重點(diǎn)考查的項(xiàng)目，通常考2～3個小題。重點(diǎn)考查的是現(xiàn)在完成時、一般過去時、過去進(jìn)行時、將來完成時、完成進(jìn)行時等，多和語態(tài)一起考查；且通常以對話的形式出現(xiàn)且常出現(xiàn)兩種時態(tài)混合在一起進(jìn)行比較。時態(tài)理解不準(zhǔn)確是考生常見的錯誤。把握住命題人的意圖是至關(guān)重要的。一般來說，命題人在考查時態(tài)這個內(nèi)容時總是設(shè)置一個語言情景來實(shí)現(xiàn)，所以理解語言情景是關(guān)鍵，同時要在這個語言環(huán)境里找到動作發(fā)生的時間或隱含的時間關(guān)系，只要理解了情景與動作的時間關(guān)系，對照選項(xiàng)，就不難把握命題意圖。注意不要斷章取義，同時還要注意時態(tài)一致。

【題目】Albert Hofmann was a Swiss scientist who was fascinated by nature. This led him to a career in chemistry in which he sought answers to his uncertainties.

【題目】In the United States the most popular form of folk dancing since the early days has been square dancing. In early times, when men and women worked in groups to build a barn (谷倉) or harvest crops, they danced when the work was done. The music came from the violin for the most part, but if there was no one to play a musical instrument, clapping（拍手）was used to produce the rhythm（節(jié)奏）by which to dance. The early settlers danced in a store, in a barn, or in a farm kitchen.

A square is formed by four couples who stand facing the centre of the square. Each couple stand on one side of the square, the boy on the left and the girl on the right.

The caller is an important part of the dance, since he tells the dancers which steps to do. If the dancers do not know the steps, he teaches them. It takes time to learn to be a good caller, and good callers are always in demand.

These are the names of some of the steps the dancers do: Form a square; Circle; Honour your partner; Swing your partner; Form a star. There are many more. As the callers tell the dancers what to do next, they move to form the pattern（圖形）he calls.

Large or small numbers of people can dance at one time. Sometimes 800 or 1,000 people may be dancing at the same time. Or there may be only one square of eight people.

Special clothes are worn by some when dancing. This makes the dance more colourful to watch. The special clothes are different from place to place. Women often wear full skirts of various colours with a pretty blouse. Men have coloured shirts and western trousers that they wear only when square dancing. In some country areas, everyone wears his best clothes.

Today in some parts of the United States you will find some schools, clubs, or groups square dancing for fun.

【題目】Are you preparing for a big test? If so, you may want to go to play some basketball in between hitting the books. Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and Science University, studies brain development. According to her research, it seems that exercise can make blood vessels, including those in the brain, stronger and more fully developed. Dr. Cameron is sure that this allows people who exercise to think better. As she says, “While we already know that exercise is good for the heart, exercise can actually cause physical changes in the brain.”

The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement show greater brain development than babies who are less physically active. Even a little movement can show big results. Margaret Barnes, a scientist, also believes in the importance of exercise. She thinks that many learning disabilities that children have in primary school or high school can result from a lack of movement as babies. Babies need movement that encourages and excites their five senses. They need to set up a connection between motion and memory. In this way, as they get older, children will begin to connect physical activity with higher learning,” says Margaret.

Older people can develop their brains as well. Cornell University studied a group of seniors who have a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for babies, exercise for older people should not be too simple. Learning some new skills or actions, such as with yoga or tai-chi helps to open up memory paths in the brain that may not have been used for a long time. For most people, any type of physical activity that increases the heart rate is helpful. The main aim is to increase the brain’s flow of blood. And your brain can benefit from as little as two to three hours of exercise a week.

【1】What is the main idea of this passage?

A. Exercise makes people strong.

B. How one can get good scores in a test.

C. Exercise can help the brain develop.

D. Brain can change one’s memory.

【2】Why is yoga suggested for the old?

A. Because it does good to the joints of old people.

B. Because it does not increase the heart rate.

C. Because it can help learn new actions.

D. Because it can be done in groups.

【3】For most people, the smallest amount of exercise required to gain any benefit is _____.

A. two hours per week B. 40 hours per week

C. three hours per day D. 40 hours per month
