But there is a downside. Tea contains caffeine which, 1 it improves mental alertness, can also cause anxiety, insomnia and other problems.

Liang Chen and Ji-Qiang Jin of the Tea Research Institute of the Chinese Academy of Agricultural Sciences have discovered just such a plant 4(grow) wild in a remote area in Fujian province, southern China. 5 they report in the Journal of Agricultural and Food Chemistry, not only is the tea plant naturally caffeine-free but it also contains a number of unique medicinal compounds that, the locals believe, offer considerable health benefits.

6(know) locally as Hongyacha, the newly discovered plant grows only between 700 and 1,000 metres 7 sea level around a handful of Chinese villages.

Now the researchers 8(explore) methods to protect Hongyacha in its natural habitat while further studies are carried out. It can take time – and sometimes it does not work – for new plant varieties 9(breed) for commercial use. A pair of naturally caffeine-free coffee plants were discovered in 2003, but little progress 10(report) Tea enthusiasts will be watching Hongyacha with interest. And others will wonder what else is out there.

這是一篇說明文。文章講述了茶因?yàn)楹杏兄诮档湍懝檀己徒档托呐K病風(fēng)險(xiǎn)的化合物,對健康有益,但茶中含有咖啡因,雖然它能提高精神警覺性,但也會導(dǎo)致焦慮、失眠和其他問題。而一種提供了所有的味道和好處,但很少或沒有咖啡因的洪崖茶被發(fā)現(xiàn)了。目前,研究人員正在探索保護(hù)洪崖茶自然棲息地的方法,同時進(jìn)行進(jìn)一步的研究。

1考查連詞。句意:茶中含有咖啡因,雖然它能提高精神警覺性,但也會導(dǎo)致焦慮、失眠和其他問題。本句為讓步狀語從句,表示“雖然”,故填although。

2考查連詞。句意:令人高興的是,一種提供了所有的味道和好處,但很少或沒有咖啡因的茶樹被發(fā)現(xiàn)。本句為主語從句,從句中缺少主語,且表示事情,故填What。

3考查代詞。表示“沒有任何”短語為none of。故填none

4考查非謂語動詞。句意:中國農(nóng)業(yè)科學(xué)院茶葉研究所的陳亮和金繼強(qiáng)在中國南部福建省的一個偏遠(yuǎn)地區(qū)發(fā)現(xiàn)了這種野生茶樹。本句中grow做非謂語動詞,與plant之間是主動關(guān)系,故填growing作后置定語,故填growing。

5考查連詞。句意:正如他們在《農(nóng)業(yè)與食品化學(xué)雜志》上發(fā)表的報(bào)告稱,茶樹不僅不含咖啡因,而且還含有許多獨(dú)特的藥用化合物,當(dāng)?shù)厝苏J(rèn)為這些化合物對健康有相當(dāng)大的好處。本句為方式狀語從句,表示“正如,正像”,故填As

9考查非謂語動詞。句意:培育新的植物品種用于商業(yè)用途可能需要時間,有時甚至是行不通的。本句中breed作非謂語動詞,且表將來應(yīng)用不定式,且與new plant varieties構(gòu)成被動關(guān)系,故用to be done形式。故填to be bred。

名詞性從句關(guān)鍵在于三點(diǎn):一、找準(zhǔn)從句在主句中充當(dāng)?shù)某煞旨捶殖鍪敲~性從句的主語句、賓語從句、表語從句還是同位語從句。二、連接詞從句中充當(dāng)?shù)某煞郑ㄖ鳌①e、定或狀語或不做任何成分)三、弄清楚每個連接詞的意義。此外還要注意,近年來高考對于名詞性從句的考查多從名詞性從句的語序和連接詞的用法區(qū)別上考查。如第二小題,句意:令人高興的是,一種提供了所有的味道和好處,但很少或沒有咖啡因的茶樹被發(fā)現(xiàn)。本句為主語從句,從句中缺少主語,且表示事情,故填What。

【題目】Directions:Read the passage carefully. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.

Life is not easy when you are looking for something worthwhile and ready to learn from the best experiences. 1 Here are some life lessons which people will learn the hard way in majority of cases.

2However, people usually get discouraged when it takes more time than they thought it would. At this time, people refer only to people who have already achieved what they want to do. Look at any successful person and you’ll notice one thing common in all of them: they took time to learn and mastered their skill like no one else. There is no elevator to success and you have to take the stairs.

Be brave to take the road less traveled. In our whole life, we always want to follow the same path that everyone suggests, do the same thing everyone does, take the same career path everyone takes, wear the same clothes everyone wears, and hang out with the same people we work with. Why? Because we are scared to fail. But when you get bored of life, you realize that you are not meant to do what everyone does and that your destiny is different from anyone else’s out there in the world. 3

You don’t have to live your life in a way society wants you to.4Parents sometimes force their children to select a career they don’t want because other children have selected that career.Worst of all, people follow them without even asking.There is no harm in believing in old beliefs but when you pursue them before your interest, sooner or later you’ll realize that you should first do what you think is right.

A. It takes continuous time and effort to be successful in any area.

B. The general rule goes that the harder you try, the greater results you get.

C. Many old beliefs are being performed these days and are followed blindly.

D. It always takes tests and then fails us to learn anything worthwhile.

E. However, in most circumstances your effort and attempt go well alongside with your desired achievement.

F. But the price we pay to realize this is high because it takes a great amount of courage to follow your own path.

Many people living in cities see riding a bicycle as good exercise. But, a recent medical 1 research warned that cyclists should think twice before cycling in the streets it actually does more harm than good 2 their bodies.

Is cycling in cities really bad for your health? Probably yes. The main danger comes from the air around you. Breathing 3 in air pollution from taxis and buses can damage blood vessels(血管).Scientists say the damage could outweigh the health benefits of cycling.

David Newby, a British 4 researcher at Edinburgh University broke the news. In his tests, 15 healthy men cycled 5 on exercise bikes in a room with levels of air pollution similar to those found 6 on a crowded city street. After an hour of cycling, the scientists found their blood vessels became less flexible and produced less of a protein(蛋白質(zhì))7 the heart needs. The damage leads to the early stages of heart disease. What's worse, the faster a cyclist pedals (蹬車),8 more air they breathe in. So those who believe 9 they are improving their fitness the most are storing up the biggest trouble for themselves 10.

【題目】The loud continuous noise of the cars or the sound of a plane can force its way into the deepest forest, yet it’s not only humans that are bothered by the noise.

Bioacoustician Bernie Krause has been studying the effect of noise pollution on wildlife, and has come across some interesting behaviors, especially among animals that communicate by vocalization(發(fā)聲), like humans. Birds use sound to communicate, but in noisy places, these animals have to shout over the natural noise to be heard.

Krause mentions a study of nightingales to clarify what he means. The birds responded to traffic noise by singing louder and louder until they actually went beyond noise pollution standards in the city. To belt out (sing loudly) their songs, they increased their lung pressure fivefold, but scientists state that this is not dangerous for the birds themselves.

Studies show that sudden noise can cause certain birds to leave their nests, exposing the young to their enemies. One study also showed that songbirds that nested close to busy motorways were much less productive than those that nested farther away. Mammals(哺乳動物)too are affected. A recent study showed that nursing caribou responded to plane noise by not producing enough milk to feed their young.

In some cases noise pollution can actually help some animals while harming others. Toads(蟾蜍)and frogs are known to vocalize in synchrony(同步;同步方式)so that no predator (their enemies) can zero in on them. Krause found that when planes flew overhead and disturbed the toad’s song, they lost their synchronicity, and it took them 45 minutes to get it back again. That gave their natural enemies plenty of time to find and catch individual toads by sound.

According to Kruse, “Not only will noise pollution bother wildlife, but it won’t help our lives either.”

1How do young caribou suffer from aircraft noise?

A. They receive less food. B. They can’t sleep at night.

C. They are often displaced. D. They can’t hear their mothers.

2What would happen if toads and frogs failed to sing in union?

A. They might become defenseless.

B. They would stop communicating.

C. They would soon regain their rhythm.

D. They might ne unable to hunt in groups.

3What is the text mainly about?

A. The effects of noise pollution on wildlife.

B. The causes of noise pollution.

C. Animals’ reaction to noises.

D. The ways animals communicate with each other.
