分析 專家認(rèn)為除非采取措施,否則我們將不會有干凈的飲用水,有關(guān)環(huán)境保護(hù)還有很多要做.

解答 答案是B.本題考查被動語態(tài);題干中第一空是unless引導(dǎo)的條件狀語從句,從句中用一般現(xiàn)在時表示將來,故排除A和C;something和do之間是被動關(guān)系,需要用被動語態(tài),排除D;remain后接動詞不定式,且much和do之間也是被動關(guān)系,故remain后的不定式用被動結(jié)構(gòu),即remain to be done有待被做,故選B.

點評 首先判斷選項中的動詞在句中是以謂語還是非謂語形式出現(xiàn),然后根據(jù)選項在句中的功能結(jié)合非謂語的基本用法做出合理的判斷.要關(guān)注常見非謂語動詞的搭配.

Enable your children to struggle for success.If your child needs summer school you explain to them why it's important.Some parents are surprised by the situation and may want to be more involved in their children's education.Follow through and follow up.
