Unit 13 Were trying to save the earth!Section B (3a-self check)【重點(diǎn)講練】1. Which parts need to be improved? 哪些部分需要被改善？辨析：need to be done; need doing與need to do need doing=need to be done 需要被現(xiàn)在分詞doing表被動(dòng)“需要被做”，相當(dāng)于need to be done。 My watch needs repairing. =My watch needs to be repaired.我的表需要修了。 need后加不定式，證明need為實(shí)義動(dòng)詞，而非情態(tài)動(dòng)詞，這時(shí)need有人稱和數(shù)的變化。 He needs to get up early. 他需要早起。【小試牛刀】單項(xiàng)選擇。Something is wrong with my car.

What or who is causing these problems? 什么或誰(shuí)將會(huì)導(dǎo)致這些問(wèn)題？cause用作動(dòng)詞，當(dāng)“引起，造成，使得”講。一般指引起或造成不好的結(jié)果。 cause sb. sth.= cause sth. to sb.(后接間接賓語(yǔ)+直接賓語(yǔ))為固定用法。He caused his parents much trouble.= He caused much trouble to his parents. 他給父母帶來(lái)很多煩惱。【小試牛刀】改為同義句。It caused him lots of worries.
