14．To our relief，the new method finally provedto be a success．

分析 令我們寬慰的是，新的方法最終證明是成功的

解答 答案是proved；本題考查語境中選用適當(dāng)?shù)脑~；prove及物動(dòng)詞，證明…；連系動(dòng)詞，證明是…，常常用于prove （to be ）+adj/n．的結(jié)構(gòu)中；題干中語境說明"證明是成功"發(fā)生在過去，故用過去時(shí)proved．

點(diǎn)評(píng) 首字母填空必須在對(duì)語境整體理解的基礎(chǔ)上抓住指向答案的關(guān)鍵線索、固定句型或搭配等，結(jié)合首字母選用恰當(dāng)?shù)脑~，同時(shí)注意所選詞的形式變化．

5．Most animals have little connection with animals of a different kind，unless they hunt them for food．Sometimes，however，two kinds of animals come together in a partnership （伙伴關(guān)系） which is good for both of them．You may have noticed some birds sitting on the backs of sheep．This is not because they want a ride，but because they find easy food in the parasites （寄生蟲） on sheep．The sheep allow the birds to do so because they remove the cause of discomfort．So although they  can manage without each other，they do better together．
Sometimes an animal has a plant partner．The relationship develops until the two partners cannot manage without each other．This is so in the corals （珊瑚） of the sea．In their skins they have tiny plants which act as"dustman"，taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe．If the plants are killed，or are even prevented from light so that they cannot live normally，the corals will die．

21．Some birds like to sit on a sheep becauseA．
A．they can eat its parasites
B．they depend on the sheep for existence
C．they enjoy traveling with the sheep

D．sheep，birds and parasites
23．We learn from the text that the coral depends on the plant forD．
A．comfort        B．light          C．food         D．oxygen
24．What does the second paragraph mainly discuss？A

2．Think about the different ways that people use wind．You can use it to fly a kite or to sail a boat．Wind is one of our cleanest and richest power sources，as well as one of the oldest．Evidence shows that windmills（風(fēng)車） began to be used in ancient Iran back in the seventh century BC．They were first introduced to Europe during the 1100s，when armies returned from the Middle East with knowledge of using wind power．
For many centuries，people used windmills to grind（磨碎） wheat into flour or pump water from deep underground．When electricity was discovered in the late 1800s，people living in remote areas began to use them to produce electricity．This allowed them to have electric lights and radio．However，by the 19 40s when electricity was available to people in almost all areas of the United States，windmills were rarely used．
During the 1970s，people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity．People also realized that the supply of coal and gas would not last forever．Then，wind was rediscovered，though it means higher costs．Today，there is a global movement to supply more and more of our electricity through the use of wind．
28．From the text we know that windmillsC
A．have rarely been used since electricity was discovered

5．Something FunA person is on trial for murder in a court room in Oklahoma．There is strong evidence indicating guilt．However，the body is not found．
In the defense's（辯護(hù)）closing statement，the lawyer，knowing that his client is guilty and that it looks like he'll probably be convicted，resorted to a clever trick．
"Ladies and gentlemen of the jury（陪審團(tuán)），I have a surprise for you all，"the lawyer says as he looks at his watch．"Within one minute，the person assumed dead in this case will walk into this court room，"he says and he looks towards the court-room door．The jury，somewhat surprised，looks at the door eagerly．A minute passes．Nothing happens．
Finally the lawyer says，"Actually，I made up the previous statement．But you all waited with expectation．I，therefore，put it to you that there is a reasonable doubt in this case as to whether anyone was killed and insist that you return a verdict（裁決）of no guilty．
The jury，clearly confused，retires to discuss．
A very few minutes later，the jury returned and a representative pronouns a verdict of guilty．
"But how？"inquires the lawyer．"You must have had some doubt； I saw all of you stare at the door．"
Answers the representative，"Oh，we did look．But your client didn't．"

24．Why was the person on trial according to the passage？B

C．Because he did not pay the tax in time．
D．Because he planned to cheat the jury．
25．Why did the lawyer come up with the trick？C
A．To find the body．
B．To annoy the jury．
C．To help his client．
D．To save himself．
26．Why did the jury look at the door eagerly？C
A．The lawyer's words must be true．
B．They expected his family to come in．
C．They were surprised and taken in by the lawyer．
D．They thought the person on trial was escaping．
27．What did the representative's answer mean in the last paragraph？B
A．They firmly believed that nobody was killed．
B．The behavior of the client gave him away．
C．The jury still needed more evidence to prove it．
D．The lawyer's words were worth thinking about．
