Dropping litter ______ never allowed in our city.

A.don’tB.a(chǎn)reC.willD.is

D

解析試題分析:句意:我們城市從來不許亂扔垃圾。結(jié)合語境可知本句描述的是客觀性動作,故用一般現(xiàn)在時態(tài),動名詞做主語表示抽象含義,故謂語動詞用單數(shù),選D。
考點:時態(tài)及主謂一致
點評:英語中的時態(tài)主要是借助于時間狀語與上下文語境來進行判斷。解答此類題型,首先要注意句子中的時間狀語,如果沒有則要通過分析上下文,結(jié)合語境來判斷句子的時態(tài)。英語中的現(xiàn)在進行時態(tài)和現(xiàn)在完成時態(tài)中的助動詞,往往因為主語的不同,而有所不同,需要注意與主語保持一致。
