I think(that)you can help me. 我想你可以帮助我。
(2)whether 与 if 引导的宾语从句:表示“是否”等一般疑问意义的宾语从句,由从属连词whether或if引导。例如:

(四)相似连词的辨析 ★★★★
1. if, whether
引导宾语从句时,既可用if,也可用whether 表示“是否”。但 whether后可直接和or not连用,if却不能。引导条件状语从句时,只能用if 表示“如果”。如:
I wonder if/whether it will rain tomorrow.
I don't know whether she will come or not tomorrow.
If I were you, I would invite him to the party.
(四)相似连词的辨析 ★★★★
2. while, when, as
(1)当某事正在进行的时候,又发生了另一件事。while, when, as 都可用来引导表示“背景”的时间状语从句。例如:
As/When/While I was walking down the street, I noticed a police car.
我沿着街道走时,注意到一辆警车。
(四)相似连词的辨析 ★★★★
(2)当两个长动作同时进行的时候,最常用的是while。例如:
While mother was cooking lunch, I was doing my homework. 当妈妈做午饭时,我正在做作业。
(3)当两个动作都表示发展变化的情况时,最常用的是as。例如:
As children get older, they become more and more interested in things around them.
随着孩子的长大,他们越来越对周围的事情感兴趣。
(四)相似连词的辨析 ★★★★
(4)当两个短动作同时发生时,或表示“一边……一边……”时,最常用as。例如:
She looked behind from time to time as she went. 她边走边不时地朝后面看。
(5)当从句的动作先于主句的动作时,通常用when。例如:
When he finished his work, he took a short rest. 当他完成工作后,他进行了短暂的休息。
(四)相似连词的辨析 ★★★★
(6)当从句是瞬间动作,主句是延续性动作时,通常用when。例如:
When John arrived, I was cooking lunch. 当约翰到达时,我正在做饭。
(四)相似连词的辨析 ★★★★
3. as, because, since, for
(1)如果是原因构成句子的最主要部分,一般用because。因此,because引导的从句往往放在句末。例如:
I stayed at home because it rained. 因为下雨,所以我待在家里。
(四)相似连词的辨析 ★★★★
(2)如果原因已被人们所知,或不如句子的其他部分重要,就用as或since。since比as稍微正式一点。as和since 引导的从句一般放在句子的开头。例如:
As he wasn't ready, we left without him. 由于他没有准备,我们没有带他就离开了。
Since I have no money, I can't buy any food. 既然我没有钱,我不能买任何食物。
(四)相似连词的辨析 ★★★★
(3)for用来补充说明一种理由,因此,for引导的从句几乎可以放在括号里。for引导的句子不放在句子的开头。例如:
I decided to stop and have lunch for I was feeling quite hungry.
我决定停下来吃午饭,因为我感觉很饿。
(四)相似连词的辨析 ★★★★
4. so...that, such...that
(1) so...that中的so是个副词,其后只能跟形容词或副词,而such...that中的such是个形容词,后接名词或名词短语。例如:
I'm so tired that I can't walk any farther. 我如此累,以至于我不能再走了。
It was such a hot day that he went swimming. 如此热的天气,以至于他去游泳。
(四)相似连词的辨析 ★★★★
(2)如果在名词之前有many, much, little, few时,用so,不用such。例如:
He has so little education that he is unable to get a job. 他受到的教育很少,以至于他找不到工作。
(四)相似连词的辨析 ★★★★
6. though与although
两个词都表示“虽然”,均不可以与but同时使用,但在句中可和still或yet连用。
although“尽管、虽然”仅作连词,比较正式,一般可以换为though。 though“虽然、尽管、即使”,还可以与even连用(=even if),表示“即使、纵然”,作副词时意思是“然而、不过”,不能放在句首。
