Yuan searched for a way to increase rice harvests 【5】 expanding the area of the fields. In 1950, Chinese farmers could produce about 56 million tons of rice.

【8】are fed

【9】countries

【10】Using

【解析】

試題分析:本文介紹“水稻之父”袁隆平的巨大貢獻(xiàn)。

【1】what 句意:袁隆平培植出了被稱作超級(jí)雜交稻的水稻。grows后跟賓語(yǔ)從句,從句缺少引導(dǎo)詞和主語(yǔ),根據(jù)句意是指物,填what。

【2】to produce it是形式賓語(yǔ),動(dòng)詞不定式真正的賓語(yǔ),故填to produce。

【3】has been 根據(jù)Since then可知此處用現(xiàn)在完成時(shí)態(tài),故填has been。

【4】disturbing 現(xiàn)在分詞前置定語(yǔ),意為“令人煩惱的”,故填disturbing。

【5】without 句意:袁在尋找一種方法在沒(méi)有擴(kuò)大種植面積的同時(shí)增加水稻產(chǎn)量。此處填without。

【6】however 句意:然而,最近的一次產(chǎn)量差不多有兩億噸水稻被生產(chǎn)出來(lái)。和以前的“56 million tons”相比較,形容現(xiàn)在的產(chǎn)量高,故此處表示轉(zhuǎn)折,又因?yàn)榇颂幱卸禾?hào),故填however。

【7】increased 產(chǎn)量是被增長(zhǎng),故此處是過(guò)去分詞作前置定語(yǔ),故填increased。

【8】are fed 被喂養(yǎng),故此處people和feed之間是被動(dòng)關(guān)系,再根據(jù)句意可知用一般現(xiàn)在時(shí)態(tài)的被動(dòng)語(yǔ)態(tài),故填are fed。

【9】countries many修飾可數(shù)名詞的復(fù)數(shù)形式,故填countries。

【10】Using 動(dòng)詞與主語(yǔ)farmers主動(dòng)關(guān)系,故用現(xiàn)在分詞作條件狀語(yǔ),故填Using。

【知識(shí)拓展】

和現(xiàn)在完成時(shí)態(tài)常連用的時(shí)間狀語(yǔ)有:lately,since then,so far,in the last/past few years, since(自從……以來(lái)),for +一段時(shí)間……等。

So far, I have learned three English songs. 到目前為止,我已經(jīng)學(xué)了三首英文歌曲。

She has taught us maths since she came here. 自從她來(lái)到這里她就教我們數(shù)學(xué)。

Long, long ago, there were a lot of donkeys. The donkeys worked hard every day. They had no time to play or to relax, but they never felt appreciated for the work they did.

One day two donkeys got bored. They wanted to live a comfortable life. So the donkeys went to see a wise old man. They told him their problem. The wise old man agreed that they worked too hard, and he wanted to help the donkeys. “I have an idea,” he said.

“What is your idea?” asked the donkeys.

“I will paint you and no one will know you are donkeys,” said the man.

The man went off to find some paint and he returned in just a few minutes. He had two pots of paint. One pot was filled with white paint, and the other black paint.

The old man first painted them white, and then painted black stripes (條紋) over the white paint. When he finished, the donkeys did not look at all like donkeys. “You no longer look like donkeys,” the old man said. “Everyone will be fooled. I will call you something else, zebras.”

The zebras went to a field to eat grass. Now they did not have to work.

Soon, other donkeys saw the zebras. They asked the zebras where they came from. When the zebras told the donkeys their secret, the donkeys all rushed to see the old man.

“Make us into zebras, too,” they pleaded. So the wise old man painted more donkeys. As he did, more and more donkeys came.

The old man could not paint fast enough. Soon the donkeys became impatient. They began to kick about, and they knocked over the paint pots.

There was no more paint. The painted donkeys ran off to become zebras. The unpainted donkeys, because of their impatience, had to return to work.

This is why it is important to be patient.

【題目】閱讀理解。

You wake up in the morning, the day is beautiful and the plans for the day are what you have been looking forward to for a long time. Then the telephone rings, you say hello, and the drama starts. The person on the other end has a depressing tone in his voice as he starts to tell you how terrible his morning is and that there is nothing to look forward to. You are still in a wonderful mood? Impossible!

Communicating with negative people can wash out your happiness. It may not change what you think, but communicating long enough with them will make you feel depressed for a moment or a long time.

Life brings ups and downs, but some people are stuck in the wrong idea that life has no happiness to offer. They only feel glad when they make others feel bad. No wonder they can hardly win others’ pity or respect.

When you communicate with positive people, your spirit stays happy and therefore more positive things are attracted.When the dagger(匕首) of a negative person is put in you, you feel the heavy feeling that all in all, brings you down.

Sometimes we have no choice but to communicate with negative people. This could be a co-worker, or a relative. In this case, say what needs to be said as little as possible. Sometimes it feels good to let out your anger back to the negative person, but all this does is to lower you to that same negative level and they won’t feel ashamed of themselves about that.

Negativity often affects happiness without even being realized. The negative words of another at the start of the day can cling to(附著) you throughout the rest of your day, which makes you feel bad and steals your happiness. Life is too short to feel negative. Stay positive and avoid negativity as much as possible.

【1】The purpose of the first paragraph is to ________.

A. make a comparisonB. offer an evidence

C. describe a daily sceneD. introduce a topic

【2】How can negative people affect us?

A. By changing our ways of thinking.

B. By telling us the nature of life.

C. By influencing our emotion.

D. By comparing their attitudes to life with ours.

【3】Some negative people base their happiness on ________.

A. making other people unhappy

B. other people’s pity for them

C. building up a positive attitude

D. other people’s respect for them

【4】According to the passage, to reduce negative people’s influence on us,we are advised to ________.

A. change negative people’s attitudes to life

B. communicate with negative people as little as possible

C. make negative people feel ashamed of themselves

D. show our dissatisfaction to negative people

注意:每空只填一個(gè)單詞。

Frederick M. Hess is the director of education policy studies at the American Enterprise Institute, which is a nonprofit organization that conducts research on many public issues. He says that a long summer vacation doesnt make sense in todays world.

Can American students afford to take a summer vacation? In a summer vacation, millions of kids spend valuable time sending messages, watching TV, playing video games and doing shopping in the mall. They will also be putting their academic futures at risk.

Summer vacation once made sense in the past when you didnt need an education to get a good job. But now things have changed. For todays students, academic skills are important to studentsfuture success, but such skills are affected in the summertime. Many nations dont give kids an American-style summer vacation. They offer no more than seven consecutive(連續(xù)的) weeks of vacation. Most American school districts offer up to thirteen weeks. To compete in the global marketplace, Americans must be prepared to go up against international competitors.

Summer vacation also causes challenges for todays families. In the 1960s, more than 60% of families had a stay-at-home Mom. Now two-thirds of American children live in households where every adult works. For these families, summer vacation can be more burden than break. Someone must watch the kids.

But the biggest problem may be how summer vacation hurts academic achievement. Researchers have found that disadvantaged students lose significant ground in the summertime.

A longer school year does not have to be an invitation to hard boring work. Rather, it should allow time-pressed teachers to conduct richer and more imaginative lessons. Schools would have more time to devote to athletics, languages, music and the arts. Summer vacation can be a grand thing. But in the 21st century, it may also be outdated.
