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

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

Doing morning exercises is good for our health. 做早操對(duì)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(yǔ)造句。

本句是個(gè)簡(jiǎn)單句,其中的how to make a sentence 是"疑問(wèn)詞+動(dòng)詞不定式"結(jié)構(gòu),在句中作謂語(yǔ)動(dòng)詞know的賓語(yǔ),make的邏輯主語(yǔ)就是I。除how外,what, which, when, where, who等疑問(wèn)詞都可用于這種結(jié)構(gòu),這種結(jié)構(gòu)除了作賓語(yǔ)外,還可作主語(yǔ)或表語(yǔ)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(gè)問(wèn)題。(作主語(yǔ))

The problem is when to start. 問(wèn)題是什么時(shí)候動(dòng)身。(作表語(yǔ))

3. I hope you will write to me soon. 我希望你會(huì)很快寫(xiě)信給我。

write to sb. 和write a letter to sb.都意為"寫(xiě)信給某人",而hear from sb.和receive/get a letter from sb.意為"收到某人的來(lái)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(lái)信。
