1. Learning a new language is fun.學(xué)一種新語言是件趣事。

動詞不能直接作主語,因此在這里要用其動名詞形式,而且其謂語動詞應(yīng)用單數(shù)形式。如:

Doing morning exercises is good for our health. 做早操對我們的健康有益。

2. I don't know how to make a sentence in English. 我不知道如何用英語造句。

本句是個簡單句,其中的how to make a sentence 是"疑問詞+動詞不定式"結(jié)構(gòu),在句中作謂語動詞know的賓語,make的邏輯主語就是I。除how外,what, which, when, where, who等疑問詞都可用于這種結(jié)構(gòu),這種結(jié)構(gòu)除了作賓語外,還可作主語或表語等。

I don't know what to do. (= I don't know what I should do.) 我不知道該做什么。

What to do next is a question.下一步做什么是個問題。(作主語)

The problem is when to start. 問題是什么時候動身。(作表語)

3. I hope you will write to me soon. 我希望你會很快寫信給我。

write to sb. 和write a letter to sb.都意為"寫信給某人",而hear from sb.和receive/get a letter from sb.意為"收到某人的來信"。

I heard from my pen pals yesterday. (=I received/got a letter from my pen pals yesterday.) 昨天我收到了我的筆友們的來信。
