13、It’s really nice to have a beautiful modern town.(P 9)
形式主语it的用法。
在英语中,当动词不定式或者that从句作主语时,常用it作形式主语,把真正的主语动词不定式或者that从句置后。It处于主语的位置,但不是真正的主语,因此英语中称之为形式主语。常用的结构为:It is+形容词/名词短语+to do/that从句。
e.g: 1. It is important to learn English well.
2. It is a hard job that he cleans the street day and night.
注意:“It is+形容词/名词短语+to do”结构中,可在不定式前面加上一个for或者of引出动词不定式的逻辑主语。当形容词是描述人的性格、品质的形容词时,用介词of,其余情况用介词for。
e.g: It is kind of you to help me a lot.
It is difficult for us to solve the problem.
② 形式宾语it的用法。
在英语中,当动词不定式或者that从句作宾语且后面接宾语补足语时,常用it作形式宾语,把真正的宾语动词不定式或者that从句置后。It处于宾语的位置,但不是真正的宾语,因此英语中称之为形式宾语。常用的结构为:think/feel/find/consider、make+it+形容词/名词短语+to do/that从句。
e.g: 1. I find it pleasant to work with him.
2. She thinks it her duty to help us.
14、It has become impossible for us to see each other as often as before.(P 9)
① impossible意为“不可能的”,impossible是由形容词possible加否定前缀im-构成的。
在英语中,形容词的否定前缀有un-,in-, im-, ir-, dis-等。
(1)大多数形容词加前缀un-构成反义词。
happy-unhappy friendly-unfriendly
(2)以c或e开头的形容词通常加前缀in-构成反义词。
correct-incorrect expensive-inexpensive
(3)以p开头的形容词通常加前缀im-构成反义词。
polite-impolite proper-improper
(4)以r或l开头的形容词,分别加前缀ir和il构成反义词。
regular-irregular legal-illegal
(5)有些形容词加前缀dis构成反义词。
honest-dishonest
② as……as before意为“和以前一样……”,as...as“和……一样”和not as/so...as...“不如……”,中间用形容词或者副词原级。
例如: My sister is as tall as me.
Tom doesn’t sing as/so well as Lucy.
15、Now I feel a bit lonely from time to time.(P 9)
① a bit意为“有点儿”,表示程度,后面跟形容词、副词原级或比较级,相当于a little。另外,a little可直接修饰名词,a bit后面加上of才可以修饰名词。
例如: I’m a bit tired.
There is a little water in the bottle.=There is a bit of water in the bottle.
② lonely作形容词,表示“寂寞的,孤单的”,强调人内心的感受;alone作形容词或者副词,意为“单独,独自”。
例如: She has few friends so she feels lonely.
The old man lives alone on the hill.
③ from time to time“不时地,偶尔”
例如: She has to work at weekends from time to time.
16、not happy because of being alone.(P 10)
because of意为“因为,由于”,后跟名词短语。在句中常和because引导的原因状语从句连用,不过because后面跟句子。
例如: We can’t go out because it rains heavily.
=We can’t go out because of the heavy rain.
17、Amazing changes have taken place in Sunshine Town.(P 10)
take place意为“发生,举行”,与happen意思相近,但略有区别。take place常指经过安排而发生的事情,happen常指偶然发生,它们都是不及物的。
例如: The World Cup takes place every four years.
An accident happened in the street just now.
18、What was the town like in the past?(P 10)
What’s sb./sth. like?一般用来询问某人/某物的特征或者性格。What does sb./sth. look like?一般用来询问某人/某物的外貌。
例如: ---What’s Tom like?
---He is very shy.
---What does your father look like?
---He is tall and thin.
