Almost 100 computers ______to us by that key school since the end of last year.

A．have givenB．had been givenC．have been givenD．had given

C

解析試題分析：考查時態(tài)和語態(tài)。本題的關(guān)鍵詞是since the end of last year.該短語與現(xiàn)在完成時連用，根據(jù)句意說明使用被動語態(tài)的形式。句意：自從去年年底以來，幾乎有100臺電腦有那所重點學(xué)校贈送給了我們。故C正確。
考點：考查時態(tài)和語態(tài)
點評：英語中的時態(tài)主要由動詞的形式?jīng)Q定，因此在學(xué)習(xí)英語時態(tài)時，要注意分析動詞形式及具體語境，想象在那個特定的時間動作所發(fā)生的背景，這個動作是經(jīng)常性動作、一般性動作、進行性動作、完成性動作還是將要發(fā)生的動作。語態(tài)是動詞的一種形式，表示主語和謂語動詞之間的邏輯關(guān)系，被動語態(tài)表示主語是謂語動詞所表示的動作的承受者�，F(xiàn)在完成時的這一用法常用ever, never以及表示次數(shù)的詞或短語作時間狀語。

A 33-year-old financial analyst in California recently quit his job to devote himself to an unpaid job teaching math on the Internet, and his lessons are reaching almost 100,000 people a month. Salman Khan’s voice is heard every day on the net --- by tens of thousands of students around the world who are hungry for help learning math. He has posted 1,200 lessons on YouTube ... lessons that appear on an electronic blackboard, which range from basic addition to advanced mathematics for science and finance. And they are free.
Khan lives in Silicon Valley, with his wife, a doctor, and their new baby. He got the idea for his “Khan Academy” four years ago, when he taught a young cousin how to convert kilograms to grams. With Khan’s help, the cousin got good at math, and Khan began a new career.
Now, Khan records his lessons himself, but he never goes on camera. “It feels like my voice in their head. You’re looking at it and it feels like someone’s over your shoulder talking in your ear, as opposed to someone at the blackboard, which is distant from you,” he said.
When Springfield High School in Palo Alto, California invited Khan to speak in person --- he immediately connected to the students there.
The idea of short lessons that can be played over and over again attracted high school senior Bridget Meaney. She says she had trouble with math in the seventh grade. “I think the teachers are good, but they can’t teach at a speed that’s perfect for everyone,” she said. “I like the idea of learning something in class but then going back and pressing pause or rewind and actually getting a deeper understanding of it.”
Originally, Khan kept his lessons short because of YouTube restrictions. Now, he thinks short is better. “Education researchers now tell me that 10 minutes is how long someone can have a high level of concentration. And anything beyond that and your brain switches off,” he said.
For Khan, teaching math, science, and finance is just the beginning. He says he’s ready to expand his YouTube site to include other subjects as well.
【小題1】What gave Khan the idea of teaching math online?

A．His success in helping his cousin learn math.
B．His discovery that many students found learning math difficult.
C．A suggestion made to him at a local high school.
D．His interest in Internet teaching.
【小題2】 Why does Khan never go on camera?
A．He’s too shy to show his face on camera.
B．It’s restricted by YouTube for education videos.
C．He wants to keep distance from the viewers.
D．He wants to create a more relaxed learning atmosphere.
【小題3】 From the passage, we know that ________.
A．Khan travels to many schools to promote his lessons
B．Khan plans to include more subjects in the future
C．Khan gives live math lessons every day for free
D．Khan set up the Khan Academy with his wife
【小題4】Why does Bridget Meaney like Khan’s lessons?
A．Khan teaches seventh grade math better than her teacher.
B．The lessons can be watched repeatedly until fully understood.
C．She can perfectly follow the pace of Khan’s teaching.
D．She cannot concentrate when learning in class.
【小題5】What does Khan mean by “short is better” in the 6th paragraph?
A．Keeping the lessons short can ensure better concentration.
B．YouTube recommends short lessons for its site.
C．Short lessons encourage students to return to the website.
D．Students enjoy short mathematics lessons more.
