---The window is dirty.
----I know. It ______ for weeks.

A.hasn’t cleanedB.didn’t clean
C.wasn’t cleanedD.hasn’t been cleaned

D

解析試題分析:句子強調對現在造成的影響是好久沒有打掃了,句子要用現在完成時。窗戶是被打掃,所以注意被動形式。句意:窗戶太臟了。我知道。它已經有好幾周沒有被打掃了。故選D.
考點:現在完成時及被動
點評:時態(tài)是高考英語的重點,單項選擇中15道有一般都是動詞時態(tài)或是語態(tài)題。可見它的重要性,所以平時要分清楚16種時態(tài)的異同,并輔助以題目進行加強鞏固,對復習階段不懂的一定要多問,并對所積累的知識進行背誦。

科目:高中英語 來源: 題型:閱讀理解

    In June, 2007, a group of students from eight high schools in Winnipeg, the capital of Canada’s Manitoba province, will begin test-launching (試發(fā)射) a satellite the size of a Rubik’s cube.

    The one-kilogram Win-Cub satellite, named for its home city and its shape, will be put into low orbit. Once in space, it can perform for a few months or up to several years, communicating information that could help find the signs of earthquakes.

    There are 80 similar satellite projects worldwide, but this is the first high-school based program of its kind in Canada. 30 Manitoba high school students are having a hand in designing and building the satellite, in cooperation with aerospace (航空航天的) experts and 10 students from the University of Manitoba, and with support from two other organizations.

    The Win-Cube project is not something that goes on a piece of paper; it is real-world engineering, allowing high school students to have an opportunity to learn more about the exciting world of engineering through their participation in this challenging program. It is also taken as a wonderful example of the unique partnerships within Manitoba. Designing, building and launching a satellite with high-school participation will bring this world-class educational project into reality and Manitoba closer to space.

    “These Manitoba high school students deserve congratulations for their enthusiasm, innovation (創(chuàng)新), and a strong love for discovery,” said Education, Citizenship and Youth Minister Peter Bjomson. “We want to make science more relevant (相關的), interesting and attractive to high school students by showing them how classroom studies can relate to practical experience in the workplace or, in this case, in space,” Bjomson added.

    The Win-Cube program is mainly named at inspiring a strong desire for discovery on the part of the students. It also shows Manitoba’s devotion to research and innovation and the development of a skilled workforce—all important drivers of knowledge-based economic growth.

56. According to the passage, the Win-Cube satellite is _________.

   A. named after Manitoba and its shape               

  B. intended for international communication

   C. designed like a Rubik’s cube both in shape and size

   D. challenged by university students around the world

57. According to Mr. Bjomson, ___________.

   A. those Manitoba high school students are worth praising

   B. the study of space can be practically made in classrooms

   C. Manitoba high schools are famous for the study of space

   D. scientific research is too far away from high school students

58. The primary purpose of the project is to _________.

   A. find the early signs of earthquakes             B. relate studies to practical

   C. help high school students study real-world engineering

   D. inspire a strong desire for discovery among the students

59. The best title for this passage may be ________.

   A. Manitoba School        B. Win-Cube Program         C. Space Co-operation

   D. Satellite Launching

科目:高中英語 來源:遼寧省本溪縣2009-2010學年高一下學期第二次月考試題(英語) 題型:閱讀理解

Thirteen, for me, was a challenging year. My parents divorced and I moved to a new town with my father, far from my old family and friends. I was terribly lonely and would cry myself to sleep each night. To ease my sadness, my father purchased an old horse for me at a local auction.(拍賣) I named him Cowboy.

Cowboy was without a doubt the ugliest horse in the world. But I didn’t care. I loved him beyond all reason. I joined a riding club and suffered rude comments and mean snickers about Cowboy’s looks. I never let on about how I felt, but deep inside, my heart was broken. The other members rode beautiful, registered horses.

When Cowboy and I entered the events where the horse is judged on appearance, we were quickly shown the gate. No amount of preparation and love would turn Cowboy into a beauty. My only chance to compete would be in the speed events. I chose the jumping race.?

One girl named Becky rode a big brown horse in the race events. She always won the blue ribbons.  Needless to say, she didn’t feel threatened when I competed against her at the next show. She didn’t need to. I came in next to last.

The stinging memory of Becky’s smirks(得意的笑) made me determined to beat her. For the whole next month I woke up early every day and rode Cowboy five miles to the arena (賽馬場). We practiced running and jumping for hours in the hot sun and then I would walk Cowboy home totally exhausted. All of our hard work didn’t make me feel confident by the time the show came. I sat at the gate and sweated it out while I watched Becky and her horse charge through the course and finish in first place.

My turn finally came. I put on my hat, rubbed Cowboy’s neck and entered the arena. At the signal, we dashed toward the first fence, jumped it without trouble and raced on to the next one. Cowboy then flew over the second, third and fourth fences like a bird and I turned him toward the finish line. As we crossed the line the crowd was shocked into silence. Cowboy and I had beaten Becky and her fancy horse by two seconds!

I gained much more than a blue ribbon that day. At thirteen, I realized that no matter what the odds, I’d always come out a winner if I wanted something badly enough to work for it.

1. The underlined expression "shown the gate" (paragraph 3) most probably means ______.

A. told how to enter the arena

B. shown how to make the horse beautiful

C. removed from the competition early

D. told to enter the timed-speed events

2. When the final race finished, nobody cheered because________.

A. the audience didn’t like Cowboy      B. people envied the writer

C. the win was unexpected?        D. the writer bad run out of time

3. Why was the writer not confident of victory?

A. He was an inexperienced rider.

B. He had not practiced enough.

C. He believed he was unpopular with the crowd.

D. He thought his horse wasn’t as good as the others.

4. What did the writer learn from his experience?

A. Life can sometimes be unfair.

B. Anything is possible if one tries hard enough.

C. A positive attitude will bring success.

D. One should not make judgments based on appearance.
