★though[ðəʊ]既可作副词，也可作连词，而且意思相近，容易混淆。现将具体区分方法介绍如下：

though——作副词，表“但是，不过”之意，置于句中（两旁加逗号，作插入语 使用）或置于句尾（其前加逗号）。此时用法等同于副词however，只不过  however使用时，可置于句首（其后加逗号）或置于句中（两旁加逗号，作插入语  使用）。

though——作副词连词，表“虽然，尽管”之意，等于although，可置于句首 （引导状语从句修饰主句，两句以逗号相隔）或置于主句之后（亦引导状语从句修  饰主句，两句间不需要逗号）。

★实战演练：

George is an American.He,though,acts very Chinese.

= George is an American.He acts very Chinese,though.

= George is an American.However,he acts very Chinese.

= George is an American;however,he acts very Chinese.

= George is an American.He,however,acts very Chinese.

乔治是个美国人，但是他的行为表现却非常中国化。

Though/Although he is nice,I don't like him.

= I don't like him though/although he is nice.

他虽然人很好，但我不喜欢他。
