20．If people eat natural poisons by mistake，they ________ go to hospital without delay．（　�。�
A．wouldB．canC．mayD．must

分析 如果人們誤吃了天然的毒素，他們必須立刻去醫(yī)院．

解答 答案是D．本題考查情態(tài)動(dòng)詞must的用法；情態(tài)動(dòng)詞must表示"必須；肯定；偏要"，本題中表示"必須去醫(yī)院"，所以答案選擇D．would表示"過(guò)去常常；會(huì)"；can表示"可能；能力；許可等"；may表示"可以；也許；祝愿等"，可見(jiàn)A、B和C均不符合題意．

點(diǎn)評(píng) 要在正確理解情態(tài)動(dòng)詞的基本含義的基礎(chǔ)上，整體理解語(yǔ)境中的情感態(tài)度，做出合理的判斷．

The hares once gathered together and complained about the dangers on all their sides．Lacking the strength and the courage to fight against their enemies，such as man and wolves，they were determined to end their miserable lives．Desperately，they rushed towards a neighboring pool，intending to drown themselves．

8．Americans who volunteer for the Peace Corps get a chance to help improve lives in developing countries．They also get a chance to learn more about the world，and about themselves．This week this program is celebrating its 50th anniversary．
President John Kennedy established the Peace Corps soon after he took office in 1961．It was the time of the Cold War between the United States and the Soviet Union．The new program gave Americans a chance to answer the call to service that the president made in his inaugural（就職的）speech．"Ask not what your country can do for you，"he said．"Ask what you can do for your country．"Kennedy told Peace Corps volunteers that America's image in the countries where they were going would depend largely on them．
On August 30th，1961，the first group of 51 Peace Corps volunteers arrived in Accra，Ghana，to serve as teachers．They had agreed to work for almost no pay．They would spend two years in Ghana helping its people and learning the reality of life in a developing country．Most of the volunteers had just completed college．About half of them taught English or health care．In the 50 years since then，more than 200，000 Americans have served as Peace Corps volunteers．They have worked in 139 countries．
The Peace Corps is a government agency that was created to promote world peace and friendship．There are three goals：First，to help the people of interested countries in meeting their need for trained men and women．Second，to help promote a better understanding of Americans on the part of the people served．And，third．to help promote a better understanding of other people on the part of Americans．
Today，the Peace Corps has more than 8，000 volunteers and trainees in 77 countries．They work in agriculture，economic development，education，the environment and health care．Some work in programs related to youth development．
Sixty percent of current Peace Corps volunteers are women．The average age of a volunteer is 28．But the ages of Peace Corps volunteers range from 18 to 86．Some Americans join the Peace Corps after they retire．Today seven percent of volunteers are over the age of 50．And 19 percent are members of minority groups．
46．Volunteers for the Peace Corps canD．
A．improve their abilities by learning in some developed countries

15．One trip for their Jack Russell terrier in a plane's cargo hold was enough to convince Alysa Binder and Dan Wiesel that owners needed a better option to get their pets from one city to another．
On Tuesday，the first flight for the husband-and-wife team's Pet Airways，the first-ever all-pet airline，took off from Republic Airport in Farmingdale，N．Y．
All commercial airlines allow a limited number of small pets to fly in the cabin．Others must travel as checked bags or in the cargo hold-a dark and sometimes dangerous place where temperatures can vary wildly．
Binder and Wiesel used their consulting backgrounds and business  savvy  to start Pet Airways in 2005．The last four years have been spent designing their fleet of five planes according to new four-legged requirements，dealing with FAA regulations and setting up airport schedules．
The two say they're overwhelmed with the response．Flights on Pet Airways are already booked up for the next two months．
Pet Airways will fly a pet between five major cities-New York，Washington，Chicago，Denver，and Los Angeles．The﹩250one-way fare is comparable to pet fees at the largest U．S．a(chǎn)irlines．
For owners the big difference is service．Dogs and cats will fly in the main cabin of a Suburban Air Freight plane，retooled and lined with carriers in place of seats．Pets （about 50on each flight） will be escorted to the plane by attendants that will check on the animals every 15 minutes during flight．The pets are also given pre-boarding walks and bathroom breaks．And at each of the five airports it serves，the company has created a"Pet Lounge"for future fliers to wait and sniff before flights．
A trip from New York to Los Angeles，for example，will take about 24 hours．On that route，pets will stop in Chicago，have a bathroom break，play time，dinner，and bunk for the night before finishing the trip the next day．
Amanda Hickey of Portland，Ore．is one of the new airline's first customers．Her seven-year-old terrier-pinscher mix Mardi and 2-year-old puggle Penny are taking their first flight soon．
Hickey said the service was a welcome alternative to flying her dogs in cargo when she transplants them from her soon-to-be Denver home to Chicago to stay while she and her fiance travel to Aruba to get married．
"For a little bit more money，I have peace of mind，"she said．

45．Jack Russell is probablyC．
A．a(chǎn) baby
B．a(chǎn) little boy
C．a(chǎn) pet
D．the couple's child
46．Which would be the best title for the passage？A
A．The first-ever all-pet airline hits skies．
B．A better option to get their pets from one city to another．
C．Flights on Pet Airways．
D．Alysa Binder and Dan Wiesel．
47．Which of the following is the service that are designed for the pets on the flight？B
a．The pets are given pre-boarding walks and bathroom breaks．
b．The attendants will check on the animals every 15minutes during flight．
c．Attendants will send the pets to the plane．
d．The pets can take a walk on the plane freely．
e．At each of the five airports it serves，there is a"Pet Lounge"for future fliers to want and sniff before flights．
A．a(chǎn)．b．c．d  B．a(chǎn)．b．c．e   C．b．c．d．e   D．a(chǎn)．b．d．e
48．What does the underlined word"savvy"in the fourth paragraph probably mean？D
A．fund   B．information  C．knowledge   D．mind．
