◆depend v.

主要意思为“依靠”、“依赖”、“取决于”等,只用作不及物动词,通常与介词 on, upon 连用,主要用法有:

1. depend on [upon]+某人或某物

Whether we’ll go camping depends on the weather. 我们是否去野营要看天气。

有时可在某人或某物后用介词 for。如:

2. depend on [upon]+某人或某物+不定式或动名词

3. depend on [upon]+从句

Our success depends on whether everyone works hard ornot. 我们的成功取决于每个人是否努力。

The amount you pay depends on where you live. 你付多少钱要看你住什么地方。

在 It (all) depends on [upon]+从句中,介词 on, upon 有时可省略(主要见于口语中)。如:

It all depends how you do it. 那要看你怎么办。

It depends (on) whether you can afford it. 这要看你是否买得起。

注:depend on [upon] 后不接 that-从句(此时须用 it)。如:

You may depend on it that he will join our club. /You may

depend on him to join our club. 你可以指望他加入我们的俱乐部。

4. 口语中说 It (all) depends. /That depends. 意为“那要看情况”。如:

A:Are you going too? 你也去吗?

B:That depends. 那要看情况。

I want to leave early but it all depends. 我想早点离开,但那要看情况。

◆dependent adj.

1. 表示“依靠的”、“依赖的”,注意以下习惯搭配:

He is dependent on his parents (for support). 他依靠父母(养活)。

Success is dependent on hard work. /Success is dependent on how hard you work. 成功取决于努力与否。

2. 比较其派生名词为 dependence(依靠,依赖)的有关搭配:

We put no dependence on him. 我们不信赖他。

He lives in dependence on his friends. 他依靠朋友生活。

3. 值得注意的是:以上两词的反义词 independent(独立的,自立的)和 independence(独立,自主,自立;不可数)却通常不连用介词on, upon, 而分别连用 of 和 from。如:

He is now independent of his parents. 他现在不依赖父母。

This money gives me independence from my family. 这笔钱可以让我不依赖家庭了。
