2023年初中條件狀語從句 要點(diǎn)

條件狀語從句

要點(diǎn)： 表示狀語從句由連詞if, unless (=if not) 引導(dǎo)。

1.if it doesn’t rain tomorrow, we will go hiking.

如果明天不下雨, 我們就去遠(yuǎn)足.

2.you will get good grades if you study hard.

如果你努力學(xué)習(xí),就會取得好成績.

3.i will go to the party unless he goes there too.

我不會去參加聚會的, 除非他也去.(如果他不去,我也不去.)

4.you will be late unless you leave immediately.

如果你不馬上走,你將會遲到的.(=if you don’t leave immediately, you will be late.)

難點(diǎn)提示：用條件狀語從句時(shí)要注意時(shí)態(tài)的正確使用,當(dāng)主句是將來時(shí)的時(shí)候,從句要用一般現(xiàn)在時(shí).

lhe will not leave if it isn’t fine tomorrow.

一般將來時(shí)， 一般現(xiàn)在時(shí)

lthey are going to have a picnic if it doesn’t rain next week.

一般將來時(shí), 一般現(xiàn)在時(shí) 考點(diǎn)　三、原因狀語從句

要點(diǎn): 由連詞because, since, as引導(dǎo), 也可由for, now that 等詞引導(dǎo)

1.i didn’t go to school yesterday because i was ill.

我昨天沒去上學(xué)，因?yàn)槲疑�病了�?/p>

2. since everybody is here, let’s begin our meeting.

既然大家都來了, 讓我們開始開會吧.

3. as you are in poor health, you should not stay up late.

既然你身體不好, 你就不該熬夜.

4.i asked her to stay to tea, for i had something to tell her.

我請她留下來喝茶,因?yàn)槲矣惺乱�告訴她.

.難點(diǎn)——because , since , as , for,辨析

在語氣上，because 最重, 表示的是直接理由,回答why 時(shí)只能用它. 其次是since, as ,一般不表示原因, 而是表明理由, 進(jìn)一步說明.(譯為：由于，既然). for 被認(rèn)為是復(fù)合句的并列連詞(常用于推斷),表示理由.
