1)主語(yǔ)
動(dòng)名詞和不定式均可以充當(dāng)句子的主語(yǔ),可以避免人稱(chēng)如“people,we”頻繁做主語(yǔ)的情況。
如:Living in school can save them a great deal of time on the way between home and school everyday.
Parents are firmly convinced that, to send their children to kindergartens or nursery schools will have an unfavorable influence on the growth of children.
考生可以模仿以上例子,結(jié)合被動(dòng)語(yǔ)態(tài)及形式主語(yǔ),更準(zhǔn)確地對(duì)其進(jìn)行使用。
2)賓語(yǔ)
非謂語(yǔ)動(dòng)詞充當(dāng)賓語(yǔ)時(shí)的用法與主語(yǔ)基本相同,值得注意的是,不定式常常以“v.+(to) do”的形式出現(xiàn)??忌鷳?yīng)在備考前總結(jié)日常作文中高頻使用的動(dòng)詞,如fail to do, prefer to do等。
如:Young adults usually prefer to take outdoor exercises rather than indoor ones.
同樣的,對(duì)于一些后面加動(dòng)名詞的動(dòng)詞,考生也應(yīng)加以熟悉,如object to, deny等。
The majority of people object to smoking in public.
在雅思作文中經(jīng)常會(huì)有對(duì)于“原因、影響、建議”的討論,或是人們對(duì)某一問(wèn)題持不同看法。我們也可以將不定式與疑問(wèn)詞連用,構(gòu)成“wh-+ to do”的結(jié)構(gòu)。
