  • 第4题:

    To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your students; you must be a clear speaker, with a good, strong, pleasing voice which is fully under you control; and you must be able to act what you are teaching, in order to make its meaning clear. Watch a good teacher, and you will see that he does not move motionless before his class; he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanation, and his face to express his feeling. Listen to him, and you will hear the loudness, the quality and musical note of his voice always changing according to what he is talking about. The fact that a good teacher has some of the gifts of a good actor doesn't mean he will indeed be able to act well on the stage, for there are very important differences between the teacher's word and the actor's. The actor has to speak words which has been learnt by heart, he has

    正确答案:B

    本题考查推理引申。第三段第一、二句提到,戏剧的主人公遭遇困难,因为他的目的与其他各种因素发生冲突,从而无法实现。这样事件就变得复杂起来,主人公能否成功地处理这些复杂事件决定了戏剧最终的结局。由此可见,复杂事件是戏剧不可缺少的部分,剧作家经常会做的事情是[B]而非[A]。[C]和[D]都只是出现了文中protagonist一词,但其论述无从推知。

    M: Hi! Are you busy right now?
    W: Oh. Hi, Scan. There’s a meeting at two-thirty, but I have a few minutes. What can I do for you?
    M: Well. I wanted to talk with you before I went to register for next semester. That’ll be my last term here’ cause I hope to transfer to the university next year.
    W: Great! Have you applied to the university yet?
    M: Not yet. The deadline’s not till March 1.
    W: Right.
    M: But I was, uh, I wanted to check with you to see if there are any other courses I still need before I transfer. I think I’ve filled all the requirements, but I, uh, just wanted to make sure before I register.
    W: All right. Let me pull up your record. Let’s see now …Sean Howard. Here we are. Hmm. All right, it looks like you’ve got all of your English and math credits, so you’re OK there, as well as your humanities and uh, social sciences. But for natural science…hmm…you took biology in your first year, but I don’t see anything after that. You’re required to have at least one more natural science coupe before you can transfer.
    M: Oh, really? I thought I needed only one science course.
    W: No, sorry, you need at least eight credits in natural science, and that means two courses.
    M: I didn’t know that. OK. Then I wonder which course I should take. What do you recommend?
    W: Next semester…let’s see…it looks like astronomy, botany, and ecology are all being offered. There’s also a course in meteorology for non-science majors.
    M: Meteorology? Do you mean, like, the weather?
    W: That’s right.
    M: Hey, that might be kind of interesting. I always wanted to know how they forecast the weather.
    W: Then that’s the fight course for you. Oh, and, Sean, it looks like you also need two credits in physical education.
    M: Physical!
    W: Right. You’re required to have four credits, and you’ve only got two so far.
    M: Oh, boy. Well, OK, that shouldn’t be too hard. Maybe I should take golf—that is offered in the spring, right?
    W: Golf? Uh…yes, it is. Do you play?
    M: Not very well, no. I’ve only played a couple of times, but I need to do better than that. My boss plays golf and he’s always talking about it. It would be nice to know what he’s talking about!
    W: Then you’d better take golf. You’ve got to play golf with your boss!
    M: OK, OK, you talked me into it! Hey, thanks for your time. I appreciate your help, and I’ll get out of your way now.

    Passage Two

    Questions 26 to 30 are based on the following passage.

    The electromagnet was invented in England by William Sturgeon,who took an iron rod and bent it into the shape of a horseshoe. This “horseshoe” was coated with varnish and a layer of copper wire was wrapped around it. An electric current was passed through the wire,thus making the rod magnetic. The rod was now,because of magnetic attraction,able to support nine pounds of iron. In the US,a scientist named Joseph Henry improved on Sturgeon's electromagnet by insulating the copper wine with silk. He was able to wrap many turns of wire around an iron core without danger of short circuits between the turns. His magnet could hold 2,300 pounds. This experiment prompted Henry to try his hand at converting magnetism into electricity. First he coiled some insulated wire around an iron bar. connecting both ends of the wire to a galvanometer(电流表). The iron bar was placed across the poles of the electromagnet. Then the coil of the electromagnet was connected to a battery. The galvanometer indicated a voltage,then dropped to zero. Henry signaled his assistant to disconnect the coil. The galvanometer showed that once again a voltage had been produced,although this time in the opposite direction. The principle of electromagnetic induction had thus been discovered. Unfortunately for Joseph Henry he did not publish his findings and someone else(Faraday)got the credit for the discovery.

    The principle of electromagnetic was discovered by______.

    A. William Sturgeon

    B. Joseph Henry

    C. Faraday

    D. someone else

    A.is not
    B.were not

    答案:D
    解析:
    考查虚拟语气。根据句子后半句中would have enjoyed结构可知是与过去事实相反,条件从句谓语结构为“had+过去分词”。句意为“如果Rick不是因为重感冒的话。他将会在他的生日聚会上玩得更好”。故选D。

    D

    much more


    正确答案: A
    解析:
    句意:每个人都有享受自由的权利,更不用说享受生活的权利了。选项A和B代入题干,均不符合语法,可先排除。much more=still more,表示“更不用说”,用在肯定句中。much less=still less,意思与much more相同,但用在否定句中。所以,本题选D。
