分析 第一篇文章介紹了加州是美國(guó)第三大州,它與眾不同之處在于它也是美國(guó)最具多元化特征的一個(gè)州,吸引了來自世界各地的人們.
第二篇文章主要介紹了克隆的兩個(gè)用途.第一,園藝師一直用它生產(chǎn)大量的供商用的植物.第二,它在對(duì)新植物物種的研究以及在對(duì)動(dòng)物的醫(yī)學(xué)研究方面都是很有價(jià)值的.

解答 1.the third largest 考查形容詞最高級(jí).根據(jù)常識(shí):加州是美國(guó)第三大州.用充數(shù)詞修飾最高級(jí),即the third largest.
2.distinction 考查名詞.根據(jù)句意:加州與眾不同之處在于它也是美國(guó)最具多元化特征的一個(gè)州.用名詞distinction,意為"不同;差異".
3.having attracted 考查現(xiàn)在分詞.根據(jù)句意:它吸引了來自世界各地的人們.a(chǎn)ttract的動(dòng)作發(fā)生謂語動(dòng)詞has之前,要用現(xiàn)在分詞的完成式.
4.live on 考查固定搭配.live on意為"繼續(xù)活著; 繼續(xù)存在",是固定搭配.
5.commercial 考查形容詞.根據(jù)句意:園藝師一直用它生產(chǎn)大量的供商用的植物.用形容詞commercial.
6.on 考查介詞.research on意為"對(duì)…的研究",是固定搭配.
7.while 考查連詞.while此處意為"而,然而(表示對(duì)比)"
8.undertake 考查動(dòng)詞不定式.根據(jù)句意:它是一項(xiàng)很難完成的任務(wù).用動(dòng)詞undertake,意為"著手做".
9.determination and patience 考查名詞. 根據(jù)句意:科學(xué)家的決心和耐心最終得到了回報(bào).用名詞determination and patience.  
10.paid off 考查固定搭配.根據(jù)句意:科學(xué)家的決心和耐心最終得到了回報(bào).pay off意為"有報(bào)償",根據(jù)時(shí)間狀語in 1996,要用一般過去時(shí)態(tài).

點(diǎn)評(píng) 在一篇200詞左右的語篇(短文或?qū)υ挘┲辛舫?0處空白,部分空白的后面給出單詞的基本形式,要求考生根據(jù)上下文填寫空白處所需的內(nèi)容或所提供單詞的正確形式,所填寫詞語不得多于3個(gè)單詞.要做好語法填空題,理解短文是解題的前提,扎實(shí)的詞匯、句型和語法知識(shí)是基礎(chǔ),英語國(guó)家的背景知識(shí)是必要的補(bǔ)充.考生須靈活運(yùn)用語法知識(shí),如單詞詞性、單詞時(shí)態(tài)、名詞單復(fù)數(shù)、連接詞、代詞、冠詞等判斷各空白處應(yīng)填寫的內(nèi)容.答完后,還要通讀全文,核對(duì)所填單詞形式是否正確,是否符合語境.

13.Many animals recognize their food because they see it.So do humans.When you see an apple or a piece of chocolate you know that these are things you can eat.You can also use other senses when you choose your food.You may like it because it smells good or because it tastes good.You may dislike some types of food because they do not look,smell or taste very nice.Different animals use different senses to find and choose their food.A few animals depend on only one of their senses,while most animals use more than one sense.
Although there are many different types of food,some animals spend their lives eating only one type.The giant panda eats only one particular type of bamboo.Other animals eat only one type of food even when given the choice.A kind of white butterfly will stay on the leaves of a cabbage,even though there are plenty of other vegetables in the garden.However,most animals have a more varied diet.The bear eats fruits and fish.The fox eats small animals,birds and fruits.The diet of these animals will be different depending on the season.
Humans have a very varied diet.We often eat food because we like it and not because it is good for us.In countries such as France and Britain,people eat foods with too much sugar.This makes them overweight,which is bad for their health.Eating too much red meat and animal products,such as butter,can also be bad for the health.Choosing the right food,therefore,has become an area of study in modern life.

1.From the text we can infer(推斷) that humans and animalsC.
A.depend on one sense in choosing food
B.a(chǎn)re not satisfied with their food
C.choose food in similar ways
D.eat entirely different food
2.Which of the following eats only one type of food?A
A.The white butterfly.
B.The small bird.
C.The bear.
D.The fox.
3.Certain animals change their choice of food whenA.
A.the season changes
B.the food color changes
C.they move to different places
D.they are attracted by different smells
4.We can learn from the last paragraph thatD.
A.food is chosen for a good reason
B.French and British food is good
C.some people have few choices of food
D.some people care little about healthy diet.
