   一.语法精讲

  1.宾语(the object

  宾语主要分为两类:直接宾语(the Direct Object)和间接宾语(the Indirect Object)直接宾语由谓语直接引起的事物是动作的直接承受者或结果,间接宾语表示动作间接承受者(给谁或为谁而做)。

  若直接宾语放在动词之后,间接宾语要用介词to或for:

  I’ll return you the book tomorrow.

  = I’ll return the book to you tomorrow.

  我明天把书还你

  Fetch us a few chairs, will you?

  = Fetch a few chairs for us, will you?

  下列动词常用for引导间接宾语:make, buy, do, fetch, get, paint, save, spare, cook, sing等。

  2.宾语表示法

  宾语可由名词,代词宾格,数词,动词不定式,v-ing形式及从句来表示。

  ①名词(代词)+不定式

②名词(代词)+动词-ing形式

③名词(代词)+形容词

④名词(代词)+副词

  (2)只能接-ing式做宾语,而不能接不定式做宾语的动词:

  iii.两者意思根本不同:

  二.重难点解释:

  1.The language which the Maori speak is related to the languages of Tahit and Hawail.

  He is learning how to drive a car.

    他在学习开车。(how在句中是不可省的)

Students Pay to Change to Popular Majors(专业)

  For most students in universities 20,000 yuan is a big sum. But Xiao Wang paid the money soon after she learned that she could change to the popular Economics Department.

By paying 20,000 yuan with the help of her parents, Xiao Wang can study the economics major she prefers. “It is difficult for graduates in chemistry to find a good job in recent years,” she said Xiao Wang in only one of the many freshmen that pay to change to popular majors. Many universities throughout China offer similar services. The charges for changing majors are from 5,000 yuan to 80,000 yuan according to recent report on the YangZi Evening News. The fee(费用)is decided by university authorities based on the popularity of each major, the report said. The most popular majors include computer science, law, finance(金融),information engineering and foreign languages. A saying popular among students may explain the phenomenon(现象).Studying a good major is much better than studying in a famous university.

Some educators warn students against rushing blindly to today’s popular majors. They may not be popular years later, the China Youth Daily said. But it seems that many students are career-oriented(以职业为宗旨的),instead of being interest-based.

Freshmen are allowed to change to other departments according to rules of the Ministry of Education. But there are no official rules on the charges. In spite of the high charges, demands to change majors are still increasing. The paper said about 100 students in the English language department of a school in Harbin changed from other departments. The department planed to admit only 50 freshmen this year.
