【答案】

 D。本题考查动词时态和语态。选项D用现在完成时,表示某一动作从过去到现在一直进行或反复发生。题干中前半部动词like用的是现在时,表示与现在有关的动作,后半部分的时间状语many times表示某个动作反复发生,因此,该空应用现在完成时。

Now and again I have had horrible dreams, but not enough of them to make me lose my delight in dreams. To begin with. I like the idea of dreaming, of going to bed and lying still and then, by some queer magic(神奇的魔力), wandering into another kind of existence. As a child, I could never understand why grown-ups took dreaming so calmly when they could make such a fuss(大惊小怪) about any holiday, This still puzzles me. I am puzzled by people who say they never dream and appear to have no interest in the subject. It is much more astonishing than it would be if they said they never went out for a walk. Most people do not seem to accept dreaming as part of their lives. They appear to see it as an irritating(令人困扰的) little habit, like sneezing or yawning(打哈欠).I can never understand this. My dream life does not seem as important as my waking life because there is far less of it, but to me it is important.

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 You Tube —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.
【小题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.
【小题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.
【小题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
【小题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.
【小题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.
