Ⅰ.单项填空
1．—Why didn’t you keep your words，Billy?
—Sorry，dear.But I really forgot where I was ________ to meet you.
A．demanded B．imagined
C．supposed D．guessed
解析：选C。句意为：“比利，你为什么食言？”“对不起，我真的忘记了我应该在什么地方见你”。was supposed to do在此句中表示“应该做某事”。
2．—Have you heard of the North Korea’s nuclear test?
—Yes，________ news came as ________ shock to me.
A．the；a B．the；the
C．a；a D．a；the
解析：选A。句意为：“你听说过朝鲜的核试验吗？”“听说了。这消息的确让我很震惊。”消息特指前文提到的核试验，所以要用定冠词。shock在此句中是可数名词，表示“一件令人震惊的事”，所以前面要用不定冠词。
3．________ I had done it I knew I had made a mistake.
A．Hardly B．Directly
C．Mostly D．Nearly
解析：选B。第一眼看四个词从形式上看都是以-ly结尾的副词，但从句子结构看，空白处需要填连词。directly/immediately等少数副词具有连词的功能用来连接两个句子，意思是“一……就……”。
4．Trains stop here in order to ________ passengers only.
A．get off B．pick up
C．pull up D．pull in
解析：选B。get off 下车；pick up 接纳乘客；pull up 停车；pull in 进站。根据后面的宾语“乘客”可知选B。
5．The film star is content with herself，and she always likes to ________ her nice figure by wearing tight dresses in public.
A．get off B．show off
C．put off D．turn off
解析：选B。句意为：这位女星太自信了，她总在公共场合穿紧身衣服来炫耀(show off)她的好身材。get off动身；put off推迟；turn off关掉(电器等)，显然不符合句意。
6．Shall we________our discussion and have some tea or coffee，please?
A．break off B．break down
C．break into D．break out
解析：选A。break off our discussion意为“打断讨论”。其他三项break down出故障；打碎，break into闯入，破门而入；break out爆发，均与句意不符。
7．I’m afraid they are now ________.We’d better go immediately to help them.
A．in the danger B．out of danger
C．in danger D．of danger
解析：选C。句意：我担心他们现在危险，我们最好立刻去帮助他们。in danger表示“处于危险中”。
8．News of the robberies _________ many people ________ fitting new locks to their doors.
A．scared；into B．scared；out of
C．scared；away D．scares；out of
解析：选A。scare...into意为“吓得某人去做某事”；scare...out of 意为“吓得某人不敢做某事”；scare away/off意为“将某人吓跑”。
9．European football is played in 80 countries，________it the most popular sport in the world.
A．making B．makes
C．made D．to make
解析：选A。此处用现在分词作状语，表示结果。
10．________tomorrow，our ship will set sail for Macao.
A．However the weather is like
B．However is the weather like
C．Whatever is the weather like
D．Whatever the weather is like

Ⅱ.阅读理解

LONDON—Britain awoke on Easter Monday to a period of mourning for the Queen Mother，who died over the weekend after a life spanning a century of noisy and evident change.The 101-year-old royal matriarch died in her sleep last Saturday with Queen Elizabeth，her elder and only surviving daughter，at her bedside.For a woman who was one of the best-known figures in Britain for more than 80 years—from the era of tinted portraits on tin biscuit boxes and cigarette cards to the age of the Internet，the Queen Mother remained an enigmatic(不可思议的)and elusive(难以达到)figure.
She achieved such a respect through aeons(永世，亿万年)of，first，fawning and，later，intrusive media fascination，by remaining almost entirely silent.Her private thoughts were never paraded(炫耀)in public.What the public saw was a charming and benign elderly lady，adept at winning the admiration of press photographers，whom she always favoured with a particular smile.
CHINA’s third unmanned spacecraft，Shenzhou Ⅲ，landed safely in central Inner Mongolia Autonomous Region Monday afternoon，after orbiting the earth 108 times in slightly less than a week.The craft，which lifted off from Jiuquan in Gansu Province last Monday night，landed after successfully conducting a chain of flight and scientific experiments over a period of 162 hours.
A powerful earthquake jolted Taiwan，killing five construction workers，authorities(官方)said.Over 200 injuries were reported across the island，mostly minor，as a result of Sunday’s 7.5-magnitude quake.The quake was centred off Hualien,180 kilometres east of Taipei.It struck at 2∶53 p．m. and lasted for nearly a minute.

解析：选D。判断题。从第3段的几个关键词safely...successfully 可知A项错误；B项内容在文中没有提及，可排除；而神舟三号为无人飞船，故不会有科学家在太空中做实验，可排除C；既然神舟三号无人飞船已安全着陆，那肯定是已成功发射了。
3．The third news mainly talks about the _________ in Taiwan.
A．political matters B．social problems
C．unexpected damage D．construction workers
解析：选C。主旨题。既然台湾发生了地震，那当然是没有预料到的灾害。A、B、D三项内容离题太远。
B

3．My cousin came to see me from the country，________ me a full basket of fresh fruits.
A．brought B．bringing
C．to bring D．had brought
解析：选B。考查非谓语动词用法。句意：我表哥从乡下来看我，带给我满满一篮子新鲜水果。此处bringing为现在分词作伴随状语。

A．killed B．killing
C．kills D．to kill
解析：选B。根据题干可知，逗号前面是个句子，前后两个部分之间没有连词，所以这里应该是非谓语形式，排除答案C；“飞机坠入山谷”和结果“杀死四个人”之间是主动关系，而且是自然而然的结果，所以排除答案A；D项的to kill表示目的，不符合语境。故答案为B项。
5．At the age of 29，Dave was a worker，________ in a small apartment near Boston and ________ what to do about his future.
A．living；wondering B．lived；wondering
C．lived；wondered D．living；wondered

6．________ many times，he finally understood it.
A．Told B．Telling
C．Having told D．Having been told
解析：选D。动作“告诉”和主语之间是被动关系，故排除B和C；再根据句意“是被告知了多次，他才最终明白”可知，强调动作的先后。故选完成时的被动语态。
7．We had an anxious couple of weeks ________ for the results of the experiment.

C．having been located D．located
解析：选D。句意为：“因为坐落在百老汇剧院和第五大道之间理想的位置，所以纽约公园宾馆是很多宾客特别喜欢的一个地方。”此题考查分词短语作状语的用法。be located 是固定短语，意思是“坐落于……、位于……”，在前半句作为整个句子的状语，表示主语的状态，locate 的逻辑主语是后面句子的主语，即 the New York Park hotel 所以排除了A项，此处不表示正在进行，所以排除了B和C项。

The space shuttle Columbia flared and broke up in the skies over Texas on Saturday，February 1,2003，killing the seven astronauts on board in what NASA and President Bush called a tragedy for the entire nation.NASA launched an investigation into the disaster and began searching for the astronauts’ remains.It said that although there had been some data failures it was too early to nail down a precise cause.The break-up,16 minutes before the shuttle was due to land at Kennedy Space Center in Florida，spread possibly toxic debris(有毒的残骸)over a wide swathe of Texas and neighboring states.
Dramatic television images of the shuttle’s descent clearly showed several white trails(痕迹)streaking through blue skies after the shuttle suddenly fell apart.It was almost 17 years to the day that the Challenger shuttle exploded on Jan.28,1986，killing all seven astronauts on board.
Take-off and re-entry into Earth’s atmosphere are the most dangerous parts of a space mission.In 42 years of US’ human space flight，there had never been an accident in the descent to Earth or landing.Challenger exploded just after take-off.
Rescue teams scrambled to search for the remains of the crew，which included the first Israeli to fly on the shuttle，former combat pilot Col.Ilan Ramon.There were warnings that parts of a vast 120-mile-long corridor of debris could be toxic because of poisonous rocket propellant(推进器)．
“We are not ready to confirm that we have found any human remains，” Nacogdoches County Sheriff Thomas Kerrs said.He added that among the roughly 1,000 calls reporting debris，some people said they found remains of crew members.
“The Columbia is lost.There are no survivors，...Their mission was almost complete and we lost them so close to home...America’s space program will go on，” said a grim-faced Bush in a message broadcast on television，which included condolences to the families of the dead astronauts.

4．Which of the following is WRONG according to the news?
A．The U．S.A.will give up the space program because of the accident.
B．NASA hasn’t found the cause of the Columbia disaster.
C．Before the Columbia disaster，no shuttles had exploded in the course of landing.

New York：When the first jet struck World Trade Center at 8∶48 a．m.on
Tuesday，the People in 2 World Trade Center with a view of the instant damage across the divide had the clearest sense of what they，too，must do：get out fast.
Katherine Hachinski，who had been knocked off her chair by the blast of heat exploding from the neighboring tower，was one of those.Despite her 70 years of age，Ms Hachinski，an architect working on the 91st floor of 2 World Trade Center，the south tower，went for the stairs.Twelve floors above her，Judy Wein，an executive (经理)，screamed and set off too.
But others up and down the 110 floors，many without clear views of the damage across the way and thus unclear about what was happening，were not so sure.And the 18 minutes before the next plane would hit were ticking off.
Amid the uncertainty about what was the best thing to do，formal announce，ments inside the sound tower instructed people to stay_put，assuring them that the building was sound and the threat was limited to the other tower.
Some left，others stayed.Some began to climb down and，when met with more announcements and other cautions(警告)to stop or return，went back up.The decisions made in those instants proved to be of great importance，because many who chose to stay were doomed(注定死亡)when the second jet crashed into the south tower，killing many and stranding(使某物留在)many more in the floors above where the jet hit.
One of those caught in indecision was the executive at Fuji Bank UAS.
Richard Jacobs of Fuji Bank left the 79th floor with the other office workers，but on the 48th floor they heard the announcement that the situation was under control.Several got in the lifts and went back up，two minutes or so before the plane crashed into their floor.
“I just don’t know what happened to them，” Mr.Jacobs said.

A．stay in the building
B．leave at once
C．put everything back and then leave
D．keep silent
解析：选A。词义猜测题。根据第四段．..formal announcements inside the sound tower instructed people to stay put，assuring them that the building was sound and the threat was limited to the other tower.及其后的伴随状语所表达的意思 “向他们保证说这幢建筑物安然无恙并且威胁局限在另一塔”可知是要人们 “留下来”，据此选 A。
7．Which floor was hit by the second jet?
A．The 91st floor. B．The 103rd floor.
C．The 60th floor. D．The 79th floor.

A．more announcements had been made
B．people hadn’t used the lifts
C．the incident had happened on a weekend
