14．He ______ his experiments and made a great contribution to our country．（　�。�
A．dived himself intoB．devoted himself into
C．devoted toD．dived into

分析 他全身心的投入到他的實(shí)驗(yàn)里，為我們的國(guó)家做出了巨大的貢獻(xiàn)．

解答 答案：B．根據(jù) made a great contribution to our country（為我們的國(guó)家做出了巨大的貢獻(xiàn)．）可知前半句表示他全身心的投入到他的實(shí)驗(yàn)里，be devoted to 和devote oneself to 表示奉獻(xiàn)于，專心于，因此答案是B．A和D表示頭朝下跳入水中，與句義不符，C應(yīng)該改成被動(dòng)．

點(diǎn)評(píng) 考查動(dòng)詞短語(yǔ)辨析． 一些短語(yǔ)既可以用主動(dòng)也可以用被動(dòng)表示同一個(gè)含義，例如
He buried himself in his work．=He was buried in his work．他埋頭工作．

5．Certain plants and animals can survive under what seem like impossible conditions．Blind fish live freely under ocean depths that are absolutely dark and cold．Bacteria live at temperatures of 600°F or a higher in places where the heat comes from the deep earth．One of the most remarkable achievements that we can observe directly is the ability of the plants and animals in the desert．
In the Death Valley，temperatures of 134°F in the shade have been officially reported Yet lizards live there，along with 600species of plants，30species of mammals？and even fish．While the days are terribly hot，the nights are extremely cold．Temperatures can fall down by as much as 50°F．
Plants called xerophytes are perfectly adapted to the extremely dry conditions．These plants have survived by developing techniques for coping with their environment．Like all living things，they must have water，and they get it in several ways．
The mesquite and the prickly （多刺的）pear pick up moisture in opposite ways．The mesquite sends its roots down as deep as 60feet to tap the water table．The prickly pear，on the other hand，spreads its roots wide．These roots are shallow but they pick up whatever moisture is available at ground level．The paloverde saves water by shedding leaves in times of extreme drought The barrel cactus makes sure of a water supply by storing water in the plant itself．The saguaro cactus stores so much water that it can survive years of drought．But even the saguaro will die sooner or later if there is no rain．All these plants，although well adjusted to their environment，must eventually get water．
Even if the parent plants die，there are always seeds to keep the species alive．Since the desert is so tough，thousands of seeds must be released to produce one plant．To get rooted，these seeds must have exactly the right conditions．They can lie dormant（休眠）for months，even years，until a little water stimulates the sparks of life．

47．Which of the following can best express the main idea of the passage？B
A．The Death Valley is a living museum，where many plants and animals exist．
B．Plants and animals can survive in the desert by adjusting to the environment．
C．Days in desert can be deadly hot，while nights can be terribly cold．
D．Bacteria survive in the ocean depth and the desert burning heat．
48．The prickly pear survives in the desert byC．
A．shedding leaves in times of drought
B．sending its roots down 60feet
C．spreading its roots wide
D．storing water in itself
49．The word xerophytes possibly comes from two Greek word roots that have the
meaning ofD
A．special techniques
B．living animals
C．water sheds
D．dry plants
50．What is the most important information the writer wants to tell readers in the last paragraph？C
A．Seeds can keep plants alive．
B．Water is a must in the desert．
C．Desert plants depend on seeds as well as water．
D Seeds get dormant for a very long time in the desert．

2．We were standing at the top of a church tower．My father had brought me to this place in a small town not far from our home in Rome．I wondered why．
"Look down，Elsa，"father said．I gathered all my courage and looked down．I saw the square in the center of the village．And I saw the crisscross （十字形） of the twisting，turning streets leading to the square．"See，my dear，"father said gently．"There is more than one way to the square．Life is like that．If you can't get to the place where you want to go by one road，try another．"
Now I understood why I was there．Earlier that day I had begged my mother to do something about the bad lunches that were served at school．But she refused because she could not believe the lunches were as bad as I said．
When I turned to Father for help，he didn't say anything．Instead，he brought me to this high tower to give me a lesson．By the time we reached home，I had a plan．
At school the next day，I secretly poured my lunch soup into a bottle and brought it home．Then I asked our cook to serve it to Mother at dinner． The plan worked perfectly．She swallowed one spoonful and sputtered（噴濺出）"The cook must have gone mad！"Quickly I told her what I had done，and Mother stated firmly that she would take up the matter of lunches at school the next day!
In the years that followed I often remembered the lesson father taught me．I began to work as a fashion designer two years ago．I wouldn't stop working until I tried every possible means to my goal．Father's wise words always remind me that there is more than one way to the square．

C．inspire her to find out another way to solve her problem
D．help her forgot some unpleasant things earlier that day

C．It couldn't be worse．
D．It was as good as her cook did．

19．Oscar the cat seems to have an unnatural ability for predicting when nursing home patients are going to die，by curling up （蜷伏） next to them during their final hours．His accuracy，observed in 25 cases，has led the staff to call family members once he has chosen someone．It usually means the patient has less than four hours to live．"Many family members take some comfort from it．They appreciate the companionship that the cat provides for their dying loved one，"said Dosa，a doctor and assistant professor of medicine at Brown University．
The 2-year-old cat was adopted as a kitten and grew up in a third-floor dementia （癡呆） unit at the Steere House Nursing and Rehabilitation Center，where the facility treats people with Alzheimer's，Parkinson's disease and other illnesses．After about six months，the staff noticed Oscar would make his own rounds，just like the doctors and nurses．He'd smell and observe patients，then sit beside people who would end up dying in a few hours．Dosa said Oscar seems to take his work seriously．"This is not a cat that's friendly to people，"he said．
"Oscar is better at predicting death than the people who work here，"said Dr．Joan Teno of Brown University，who treats patients at the nursing home and is an expert on care for the terminally ill．She was convinced of Oscar's talent when he made his 13th correct call．While observing one patient，Teno said she noticed the woman wasn't eating，was breathing with difficulty and that her legs had a bluish color，signs that often mean death is near．Oscar wouldn't stay inside the room，though，so Teno thought bis streak was broken． Instead，it turned out the doctor's prediction was roughly 10 hours too early．Sure enough，during the patient's final two hours，nurses told Teno that Oscar joined the woman at her bedside．
Doctors say most of the people who get a visit from the sweet-faced，gray-and-white cat are so ill that they probably don't know he's there，so patients aren't aware he's a predictor of death．Most families are grateful for the advance warning，although one wanted Oscar out of the room while a family member died．When Oscar is put outside，he paces and meows his displeasure．
No one's certain if Oscar's behavior is scientifically significant or points to a cause．Teno wonders if the cat senses mysterious scents or reads something into the behavior of the nurses who raised him．Nursing home staff aren't concerned with explaining Oscar，so long as he gives families a better chance at saying goodbye to the dying．The staff recently gave Oscar a wall sign publicly praising his"sympathetic care．"

41．What makes Oscar the cat so special？D
A．He observes the cases of dying patients． B．He curls up next to the patients．
C．He calls family members to the hospital． D．He senses when patients are to die．
42．The passage tells us OscarA．
A．would go round and observe patients         
B．may sometimes fail to predict death
C．is friendly and liked by every nurse         
D．was born and grew up in the hospital
43．The underlined words "his streak was broken" probably meanB．
A．his bones were severely injured             B．his magic power stopped working
C．his devotion to work got changed            D．his friendship with patients ended
44．From the passage，we learn thatC．
A．Oscar's behavior is scientifically significant      
B．Oscar can read something of the nurses'behavior
C．Oscar might like to stay with the dying patients   
D．Oscar is sympathetic to the dying patients
45．The best title for this passage is"C"．
A．Cats Can Be Used for Looking After Patients      
B．Oscar，the Sweet-Faced，Gray-and-White Cat
C．As Death Comes Calling，So Does Oscar the Cat    
D．Oscar the Cat，the Best Helper of Our Hospital．
