Las Vegas is（62）awonderful city．There are many of the largest（63）hotels （hotel）in the world．Las Vegas offers fun and excitement as well as the（64）natural（nature）beauty of the desert．It is a big desert，but no other places in America are（65）more attractive （attractive）than it now．

分析 文章講述了作者去拉斯維加斯的經(jīng)歷．我一直盼望去拉斯維加斯，上個周末終于夢想成真．拉斯維加斯是一個很棒的城市，那里有世界上最大的旅館，還有美麗的沙漠美景．只不過氣候炎熱，白天我呆在賓格，晚上再出去．有人說去拉斯維加斯的每個人都會玩得很開心．

解答 答案：61．visiting；考查動名詞．句中l(wèi)ook forward to盼望，后接名詞或動名詞．
62．a(chǎn)；考查冠詞．句意表達(dá)的是泛指一個城市，要用不定冠詞．  
63．hotels；考查名詞．句中有many修飾，名詞要用復(fù)數(shù)．  
64．natural；考查形容詞．句中nature修飾名詞beauty，要用形容詞形式．    
65．more attractive；考查比較級．句中有than表示比較，要用形容詞的比較級；attractive是多音節(jié)單詞，要添加more來構(gòu)成比較級．
66．which；考查連詞．句中is disappointing修飾前面整個句子的內(nèi)容，是一個非限制性定語從句；從句缺少主語，且表示一件事，要用which來引導(dǎo)．  
67．to have；考查短語搭配．go out to do sth出去做某事；不定式作目的狀語． 
68．but；考查連詞．句意表達(dá)的是轉(zhuǎn)折，要用but來連接表示轉(zhuǎn)折關(guān)系的并列句．   
69．interesting；考查形容詞．句中有most表示最高級，且句意表達(dá)的是事物，要用現(xiàn)在分詞構(gòu)成的形容詞形式．  
70．such；考查短語搭配．such…that…如此…以致…；such修飾名詞或名詞短語．

點評 語法填空題是考查學(xué)生的語言運用能力．解題時，要在理解文章的基礎(chǔ)上，靈活運用語法知識，如詞性，時態(tài)，名詞單復(fù)數(shù)，連接詞，代詞，冠詞等判斷空白處應(yīng)填寫的內(nèi)容．答完后，還要通讀全文，核對所填單詞形式是否正確，是否符合語境．

2．In my profession as an educator and health care provider，I have worked with numerous children infected with the virus that causes AIDS．The relationships that I have had with these special kids have been gifts in my life．They have taught me so many things，but I have especially learned that great courage can be found in the smallest of packages． Let me tell you about Tyler．
Tyler was born infected with HIV：his mother was also infected．From the very beginning of his life，he was dependent on medications to enable him to survive．When he was five，he had a tube surgically inserted in a vein in his chest．This tube was connected to a pump，which he carried in a small backpack on his back．Medications were hooked up to this pump and were continuously supplied through this tube to his bloodstream．At times，he also needed supplemented oxygen to support his breathing．
Tyler wasn't willing to give up one single moment of his childhood to this deadly disease．It was not unusual to find him playing and racing around his backyard，wearing his medicine-laden backpack and dragging his tank of oxygen behind him in his little wagon．All of us who knew Tyler marveled at his pure joy in being alive and the energy it gave him．Tyler's mom often teased him by telling him that he moved so fast she needed to dress him in red．That way，when she peered through the window to check on him playing in the yard，she could quickly spot him．
This dreaded disease eventually wore down even the likes of a little dynamo like Tyler．He grew quite ill and，unfortunately，so did his HIV-infected mother．When it became apparent that he wasn't going to survive，Tyler's mom talked to him about death．She comforted him by telling Tyler that she was dying too，and that she would be with him soon in heaven．
A few days before his death，Tyler beckoned me over to his hospital bed and whispered，"I might die soon．I'm not scared．When I die，please dress me in red．Mom promised she's coming to heaven，too．I'll be playing when she gets there，and I want to make sure she can find me．"

64．What is the boy Tyler's attitude towards death？B
A．pessimistic．     B．optimistic．
C．sorrowful．       D．fearful．
65．Tyler requested the writer to dress him in red when he died simply becauseC．
A．red is a lucky color           
B．red might help to cure him
C．his mom could spot him easily  
D．he could find more mates by wearing red
66．Which of the following might serve as a possible title for this passage？D
A．My unusual profession．     B．A caring mother．
C．Mother and son．            D．Dying in red．
67．The underlined word dynamo in the fourth paragraph here meansB．
A．a(chǎn) promising and helpful youth
B．a(chǎn)n extremely energetic person
C．a(chǎn) rare and beautiful flower
D．a(chǎn) magic and understanding superstar．

4．How do predators （獵食動物） affect populations of the prey （獵物） animals？The answer is not as simple as might be thought．The Moose（麋鹿） reached Isle Royale in Lake Superior by crossing over winter ice and bred freely there in isolation without predators．When wolves later reached the island，naturalists widely assumed that the wolves would play a key role in controlling the moose population．Careful studies have demonstrated，however，that this is not the case．The wolves eat mostly old or diseased animals that would not survive long anyway．In general，the moose population is controlled by food availability，disease and other factors rather than by wolves．
When experimental populations are set up under simple laboratory conditions，the predator often wipes out its prey and then becomes extinct itself．However，if safe areas like those prey animals have in the wild are provided，the prey population drops to low level but not extinction．Low prey population levels then provide inadequate food for the predators，causing the predator population to decrease．When this occurs，the prey population can rebound．In this situation the predator and prey population may continue in this cyclical pattern for some time．
Population cycles are characteristic of small mammals，and they sometimes appear to be brought about by predators．Ecologists studying hare populations have found that the North American snowshoe hare follows a roughly ten-year cycle．Its numbers fall tenfold to thirty in a typical cycle，and a hundredfold change can occur．Two factors appear to be generating the cycle：food plants and predators．
The preferred foods of snowshoe hares are tender willow branches．As the hare population increases，the quantity of these branches decreases，forcing the hares to feed on low-quality high-fiber food．Lower birth rates and low growth rates follow，so there is a corresponding decline in hare abundance．Once the hare population has declined，it takes two to three year for the quantity of branches to recover．
A key predator of the snowshoe hare is the Canada lynx．The Canada lynx shows a ten-year cycle of abundance（大量） that parallels the abundance cycle of hares．As hare numbers fall，so do lynx numbers，as their food supply decreased．
Predators are an essential factor in maintaining communities that are rich and diverse in species．Without predators，the species that is the best competitor for food，shelter，and other environmental resources tends to dominate and exclude the species with which it competes．This phenomenon is known as"competitor exclusion"．However，if the community contains a predator of the strongest competitor species，then the population of that competitor is controlled．Thus even the less competitive species are able to survive．From the stand point of diversity（多樣性），it is usually a mistake to eliminate a major predator from a community．

73．The author uses the example of the moose and wolves on Isle Royale toB．
A．provide evidence that predators influence prey populations
B．question the belief in the effect of predators on prey populations
C．demonstrate predator population grows faster than that of the prey
D．prove that studies of isolated populations tend to be useful
74．The word"rebound"in the passage is closest in meaning toD．
A．React
B．Resist
C．Remain
D．Recover
75．Which of the following is true according to the passage？A
A．Laboratory results can't explain the changes in predator and prey populations of the wild．
B．The growth of hare population may lead to a corresponding increase in its birth rates．
C．The experimental environments can promote the growth of predator and prey populations．
D．The existence of a major predator in a community is a threat to the diversity of species．
76．What can we conclude from the passage about the cycle of the Canada lynx？C
A．When hare numbers decrease，lynx numbers increase．
B．It has a great effect on the number of snowshoe hare．
C．It closely follows the cycle of the snowshoe hare．
D．It is not directly related to the availability of lynx food．
77．What is the best title of this passage？B
A．What role predators play in keeping competitor species．
B．Whether predators have an impact on prey populations．
C．A study of the populations of the predator and prey animals．
D．Contributing factors of the changes in animal populations．
