  肯定句:She is a teacher.

  否定句:She is not a teacher.

  一般疑問句: Is she a teacher?

  2. 行為動詞:主語+行為動詞(+其它)。如:

  Mary likes Chinese.瑪麗喜歡漢語。

  行為動詞的變化

  否定句:主語+don't(doesn't)+動詞原形(+其它)。如:

  三、現(xiàn)在進(jìn)行時

  1. 現(xiàn)在進(jìn)行時表示現(xiàn)在正在進(jìn)行或發(fā)生的動作,也可表示當(dāng)前一段時間內(nèi)的活動或現(xiàn)階段正在進(jìn)行的動作。

  2. 基本結(jié)構(gòu):①be going to + do; ②will+ do.

  3. 否定句:在be動詞(am, is, are)l后加not或情態(tài)動詞will后加not成won’t。

  例如:I’m going to have a picnic this afternoon.→ I’m not going to have a picnic this afternoon.

  4. 一般疑問句: be或will提到句首,some改為any, and改為or,第一二人稱互換。

  例如:We are going to go on an outing this weekend. → Are you going to go on an outing this weekend?

  特殊疑問句:

  ⑴疑問詞+did+主語+動詞原形? 如:What did Jim do yesterday?

 ?、埔蓡栐~當(dāng)主語時:疑問詞+動詞過去式? 如:Who went home yesterday?

  動詞過去式變化規(guī)則:

  習(xí)題講解

  1.David _________making model ships, but Mike doesn’t.

  A: like B:likes C: is like

  解析:正確答案B。這里是like的用法,因為David是第三人稱故A排除,C中is like 表示像什么,根據(jù)句意本題應(yīng)該是David喜歡做模型船。

  2.---What are you going to do next week?

  ---I___________in the sea.

  A:am going to swim B:am swimming C:swim

  解析:正確答案是A。問題里面的next week表示將來時,根據(jù)語法結(jié)構(gòu)將來時應(yīng)該用be going to do,故選A。

  成語雙語故事:指鹿為馬

  call black white (and white black)

  指鹿為馬

  In Qin dynasty, there was a powerful and evil counselor named Zhao Gao.

  在秦朝,有個很得勢的奸臣叫趙高。

  Zhao Gao wanted to rebel, but he didn‘t know how many people in the court would stand by his side.

  趙高想造反,但是又不知道群臣中有多少人會支持他。

  So he worked out a way to test the people.

  于是他想了個辦法來測試。

  He presented a deer as a tribute to the emperor in front of the court, and said that it was a swift horse.

  他在群臣面前送了一頭鹿給皇上,并說這是一匹千里馬。

  The emperor not accepting his statement said, “This is obviously a deer.”

  皇上不信,說“這明明是鹿啊?!?/p>

  Then, Zhao Gao took this opportunity to ask the court, “Is this a deer or a horse?”

  然后趙高借機(jī)問各位大臣,“這是鹿還是馬?”

  In the court, those who didn’t dare to go against Zhao Gao agreed with him and said that it was a horse, those who dared to go against Zhao Gao said that it was a deer.

  在大臣中,不敢反抗趙高的都贊同說是馬,敢于反對趙高的說是鹿。

  Later, Zhao Gao remembered the counselors who didn‘t agree with him and persecuted them to solidify his power.

  后來,趙高記住了這些反對他的人并加以迫害,以鞏固自己的勢力。

  This story is still popular even today. People use this idiom to describe someone who calls white black.

  這個故事流傳至今,人們用這個成語來形容一個人顛倒黑白。

  英語中表達(dá)“指鹿為馬”意思的短語可以用“call black white (and white black)”,意思也就是“把黑的當(dāng)白的,把白的當(dāng)作黑的”,這樣也就是顛倒是非啦~
