Module 5課文重點、難點解析

1. Iron doesn't rust in dry air. 在干燥的空氣中鐵不容易生銹。

在此處rust作不及物動詞,說明主語的特征。謂語動詞要用主動形式。常見的同類動詞有:sell, write, dry, wash, open, move, lock等。例如:

The oranges sell well. 這些橘子很暢銷。

注意區(qū)分:系動詞taste, look, smell, feel, sound等后面要接形容詞作表語。例如:

The oranges taste good. 橘子嘗起來好吃。

2. Half-fill a test tube with water. 給玻璃試管灌一半水。

fill...with使......充滿;be filled with... 用......裝滿

類似的詞組有:

be crowded with擠滿

be covered with 被......覆蓋

be marked with 標上......記號

be dotted with用......點綴著

be lined with 沿著;兩旁排列著

be equipped with 用......裝備

3. I never used to enjoy science, but last year I changed schools, and the science teachers at my new school are excellent. 我過去從來沒有喜歡過理科,但去年我換了學校,而且新學校的理科老師們非常出色。

used to do sth. 表示過去常常做某事。例如:

John used to visit his parents once a week when he worked as an assistant in the city.約翰在城里當服務(wù)員的時候,總是每周去看望父母一次。

拓展:1) be used to do sth. 被用來做某事。例如:

Wood can be used to make paper. 木材可以用來造紙。

2) be/get used to sth./ doing sth. 習慣于做某事。例如:

He was used to sleeping with the windows open. 他習慣敞著窗子睡覺。

4. The Noble Prize is the highest scientific prize there is,so we should be very proud of that。諾貝爾獎是科技領(lǐng)域曾有過的最高獎項,因此我們應(yīng)以此為驕傲。

此處there is 是定語從句,修飾prize,表示曾有過的。例如:

The home improvements have taken what little there is of my spare time. (NMET2001)房屋裝修占據(jù)了我那么少的業(yè)余時間。

5. ...as both are supposed to have good physics Departments.因為兩所大學都應(yīng)該有最好的物理系。

be supposed to +不定式短語,可以表示"應(yīng)該""理應(yīng)"含有"本來應(yīng)該做某事,而事實上并非如此"之意。例如:

Everyone is supposed to wear a seat belt in the car. 坐車時每個人都應(yīng)該系安全帶。
