A newly discovered tea plant is caffeine-free

The world loves tea and some 3m tons of tea are consumed every year. Tea can be good for health, as it contains compounds that help to lower cholesterol(胆固醇)and reduce the risk of heart disease. But there is a downside. Tea contains caffeine which, 1 it improves mental alertness, can also cause anxiety, insomnia and other problems.

2 would be agreeable is that a tea plant that provides all the taste and goodness but with little or 3 of the caffeine has been found. 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.

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.

【解析】

这是一篇说明文。文章讲述了茶因为含有有助于降低胆固醇和降低心脏病风险的化合物,对健康有益,但茶中含有咖啡因,虽然它能提高精神警觉性,但也会导致焦虑、失眠和其他问题。而一种提供了所有的味道和好处,但很少或没有咖啡因的洪崖茶被发现了。目前,研究人员正在探索保护洪崖茶自然栖息地的方法,同时进行进一步的研究。

1考查连词。句意:茶中含有咖啡因,虽然它能提高精神警觉性,但也会导致焦虑、失眠和其他问题。本句为让步状语从句,表示“虽然”,故填although

2考查连词。句意:令人高兴的是,一种提供了所有的味道和好处,但很少或没有咖啡因的茶树被发现。本句为主语从句,从句中缺少主语,且表示事情,故填What

3考查代词。表示“没有任何”短语为none of。故填none

4考查非谓语动词。句意:中国农业科学院茶叶研究所的陈亮和金继强在中国南部福建省的一个偏远地区发现了这种野生茶树。本句中grow做非谓语动词,与plant之间是主动关系,故填growing作后置定语,故填growing

5考查连词。句意:正如他们在《农业与食品化学杂志》上发表的报告称,茶树不仅不含咖啡因,而且还含有许多独特的药用化合物,当地人认为这些化合物对健康有相当大的好处。本句为方式状语从句,表示“正如,正像”,故填As

6考查非谓语动词。句意:这种新发现的植物在当地被称为洪崖茶,海拔只有7001000米,生长在中国少数几个村庄附近。固定短语be known as“被称为;作为……被熟知”,这里是过去分词作状语,故填Known

7考查介词。表示“在……上面”,海平线1000米以上,故填above

8考查动词时态语态。句意:目前,研究人员正在探索保护洪崖茶自然栖息地的方法,同时进行进一步的研究。根据now可知,使用现在进行时,主语是为researchers复数名词,故填are exploring

9考查非谓语动词。句意:培育新的植物品种用于商业用途可能需要时间,有时甚至是行不通的。本句中breed作非谓语动词,且表将来应用不定式,且与new plant varieties构成被动关系,故用to be done形式。故填to be bred

10考查动词时态语态。句意:2003年,人们发现了两种天然的不含咖啡因的咖啡树,但至今鲜有报道。本句主语与谓语动词构成被动关系,且表示“自2003年到今天”为动作的持续应用现在完成时,主语为little progress,故填has been reported

名词性从句关键在于三点:一、找准从句在主句中充当的成分即分出是名词性从句的主语句、宾语从句、表语从句还是同位语从句。二、连接词从句中充当的成分(主、宾、定或状语或不做任何成分)三、弄清楚每个连接词的意义。此外还要注意,近年来高考对于名词性从句的考查多从名词性从句的语序和连接词的用法区别上考查。如第二小题,句意:令人高兴的是,一种提供了所有的味道和好处,但很少或没有咖啡因的茶树被发现。本句为主语从句,从句中缺少主语,且表示事情,故填What

【题目】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.

【题目】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(发声), 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(哺乳动物)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.
