首先非谓语动词包括:不定式、动名词、分词(现在、过去分词).
1Hislefteyeinjured,hefailedtonoticetheinstructionofleavingthefrontline.(leaving,动名词)
2I'mhappytoknowthatheishappy.(toknow,不定式)
3I'msureofmyfellow‘stakingthemicroscopetotheofficelastSaturday.(这里你要是较真的话,用company,但office更口语一些).这句话非要用非谓语动词,写出来还挺别扭的.
4Pleaseputthoseclothhangingovertheceilingandeggslaidyesterdaytothesouth-facingroom.(这个句子里很多非谓语啊,hanging,laid.是分词)
5WhenIwenttotheclassroomtoaskhimforexperimentsuggestion,hehappenedtomakedumplingsbyhisclumsyhandsinthekitchen.(你的中文前半句写错了吧,后面说碰巧在厨房,前面应该是在家才说得通呢)(toask不定式)
6Thedamfinishedlastyearcanplythenewplantwithsufficientpower.(前面finished是分词作非谓语)
