Though I like writing to my penfriend , it takes a lot of time . 虽然我喜欢给笔友写信,但花了很多时间。

※ 由连词 though ( 虽然 ) 引导的状语从句,全句中有“但是”之意,然而 thought 与 but 不能前后连用,只能用其中一个。上句也可以说成:

I like writing to my penfriend , but it takes a lot of time .

※ though 引出的从句放在句首时,从句后面要有逗号。但也可将 though 引出的状语从句放在主句之后。

Though it was raining , he went there .

He didn\'t do this work well though he did his best . 虽然他尽了最大努力,但还是没干好这工作。

※ though 常与 even 连用,表示强调。如:

Even though I didn\'t understand a word , I kept smiling .

2 . 由 after 引导的时间状语从句的句型

But after we left the mountains behind us , there was hardly a cloud in the sky . 然而当我们把群山峻岭甩在后面后,天空几乎万里万云。

※ after we left the mountains behind us,是由连词 after 引导的时间状语从句。引导时间状语从句的还可由 when , while , before , till , since 等词引起。

leave behind 是“把 ( 某物 ) 留在 ( 某物 ) 的后面”。

由 after 引导的时间状语从句举例如下:

After we had finished lunch , we all sat on the grass .

※ after 引导的从句,有时放在主句之后。如:

I arrived at the station after the train had left .

3 . They say that… = It is said that … 据说

…and they say that there are ten sheep for every person . 据说每人占有十头羊。

句中的 they 并没有具体的对象,泛指人们 ( people ) 。

They say that… = People say that… = It is said that… 如:

It is said that he will leave in a few days . 据说他过几天就要动身。

4 . How often do you write ? 你们隔多久通一次信 ?

( 1 ) How often 常用来询问动作的频率,回答可用:some times/very often/not too often/once/twice/three times a year…有时/经常/一年一次 ( 二次/三次 ) 等。例如:

—How often do you go to see your grandmother in the countryside ? 你多久去看一次住在农村的祖母 ?

—Twice a year . 一年去两次。

( 2 ) 注意下面以 how 提问的句子的准确含意。

—How long have you waited here ?

— For about two hours .

how long 表示动作或状态“延续的时间”。

—How much time did you spend on this work ?

— Just a week .

how much time 表示一个“总的时间量”。

neither 意为:两者中任意一个“都不”。所以句中的相关动词或名词应该用单数形式。此句中用 has , 不能用 have。句中的 neither 是代词。例如:

Neither answer is right . 两个答案都不对。 ( 两者中,无论哪个答案都不对。 )

句中的 neither 是形容词,名词 answer 及动词 be 都用单数形式。

Neither of them knows her . 他们俩都不认识她。

6 . Both John and Ann have got penfriends . 约翰和安 ( 两人 ) 都有笔友。

( 1 ) both…and…“对方都;又……又……”,构成关联连词。例如:

She is both beautiful and kind . 她又漂亮又亲切。

She can both sing and dance . 她能歌善舞。

( 2 ) both 在句中还常作形容词和代词。例如:

Both brothers are in Japan . ( both 是形容词 )

Both of the brothers are in Japan . ( both 是代词 )

I saw them both yesterday .

They both went out .

neither…nor…与 either…or…的用法:

neither…nor… ( 连词 ) “既不……又不……”。例如:

It is neither hot nor cold .

Neither you nor he is right . = Neither he nor you are right .

either…or… ( 连词 ) “或……或……”。例如:

Either you or he is right . = Either he or you are right .

7 . …but I can\'t spend much time on it . ……但我不能在它上面花很多的时间。

( 1 ) spend time on something “在某事上花时间”。例如:

I spent two hours on my homework .

( 2 ) spend money on something “花钱买东西”。例如:

He spent about four hundred yuan on this bicycle .

( 3 ) spend time ( in ) doing something “花时间做某事”。例如:

The young man spent three years ( in ) writing that book .

8 . Though I like writing to my penfriend , it takes a lot of time . 虽然我喜欢给笔友写信,但花了很多时间。

( 1 ) though 连词,“虽然”,引出一个状语从句。汉语中常说“虽然……但是……”,但在英语中用了 though , 就不用 but ; 同样用了 but 就不用 though。上面的句子也可说成:I like writing to my penfriend , but it takes a lot of time .

( 2 ) though 引出的从句放在句首时,从句后要写逗号,也可将 though 引出的从句放在主句后。例如:

Though it rained heavily , the football match still went on .

He didn\'t do this work well though he did his best .

9 . We\'ve just returned from a short holiday at Ayers Rock . 我们刚从艾尔斯山短期度假归来。

( 1 ) return from a holiday “度假后回来”

( 2 ) Ayers Rock “艾尔斯山”,澳大利亚中部山脉。

10 . …so we flew most of the way . ……所以我们大部分旅途都乘飞机。

( 1 ) so 在此意为“因此,所以”,在句中作连词,因此不能说成 because…so… , 两个词只能分别使用一个。

( 2 ) flew 是 fly 的过去式。

11 . From Sydney we flew over a line of mountains in the southeast . 从悉尼起飞,我们越过澳大利亚东部的一系列山脉。

( 1 ) fly over “飞越”。over 意为“在……上面” ( 指空间 ) 。例如:

There is a light over Li Ming . 李明的上方有一盏灯。

( 2 ) a line of mountains 意为“群山”。

12 . But after we left the mountains behind us , there was hardly a cloud in the sky . 然而当我们把群山峻岭甩在后面时,天空几乎万里万云。
