Step 2. Language points
1.spend…(in/on) doing sth.
花费时间(金钱)做某事
(1) cost 表示“花费(多少钱)” “需要(多少钱)”,主语一般是表示所买东西的名词,不能是表示人的名词
sth. costs money/ cost one’s life
at the cost of 以…为代价
(2)spend money on 和 pay money for 都可用来表示花钱买东西
(3)take和spend在表示“花费(时间)”时所用的句型不同
take常用于:
It takes (sb.)+time+to do sth.
It是形式主语,不定式是真正的主语。
spend 常用于: spend time (in) doing sth./spend time on sth.
主语是人,注意介词in后面是v.-ing的形式,in可省去,on后面通常是名词
2. something后面的句子“he had noticed again and again”为定语从句,省去了“that”.
3. in a short time 立刻,很快 ahead of time 提前
at any time 随时 at one time 从前
at times 偶尔,有时 many a time 多次,屡次
in no time 立刻,马上 at a time 一次
time after time=time and time again屡次
4. to one’s surprise=to the surprise of… 令…惊奇的是
to one’s delight (joy) 使…高兴的是
to one’s sorrow 使…悲伤的是
5. over and over again 一次又一次
over and over again time and time again
many a time time after time
6. far away用作表语或状语
far-away用作定语
far away from只表示距离
far from除了表示距离的“远离”之外,还有“远远不,完全不,决非”之意,后接名词、动名词或形容词。Far from perfect/satisfactory/the truth
They don’t live far (away).
They live at a far-away place.
The school is far (away) from my house.
I’m far from (being) happy in my present job.
7. the +比较级,
the +比较级…
(1)”(从句)the+adj./adv.的比较级…,(主句)the+adj./adv.的比较级…”这种句型表示前者和后者在程度上同样增加或同样减少,
要注意这一句型中的“the”并不是冠词,前面的“the”是关系副词,有“by how much”之意;后面的“the”是指示副词,有“by so much”之意,前面是状语从句,后面是主句,前后呼应,
表示“越…就越…””愈是…,则愈是…”
[注]此结构中的比较级可以是形容词,也可以是副词,主句如用一般将来时,前面的状语从句通常用一般现在时代替一般将来时 。
The sooner you begin your work, the sooner you will finish it.
你越早开始工作,就越早完成它。
The more he thought of it,the happier he felt.
这件事他越想越高兴。
(2)此外,该句型可省略的成分较多,不仅后面出现的与前面相同的成分可以省略,当主语、谓语等在一定的情景或场合中意思明了时,也可以省略不用, 这种情况在口语中尤其常见。
The more, the better.多多益善。
The sooner, the better.越早越好。
8. come to light vi.显露,为人所知
His past came to light.
=His past was brought to light.
9.remain vi. 剩余,残余

当remain和stay作“保持,(人)留下“讲时,可以互换。
当表示“剩下、还有”时,通常只有remain,不用stay
当表示“暂住”时,用stay,不用remain.
I stay in a hotel when I was in Beijing.
