Answer 1

分析 空氣污染，加上亂丟垃圾，在我們今天的大工業(yè)城市導(dǎo)致了許多問題．

解答 答案A．
根據(jù)句中的時(shí)間狀語today，可排除C；橫線處缺少謂語動詞，而causing是非謂語動詞，可排除D．當(dāng)主語為單數(shù)名詞或代詞，盡管后面跟有with，together with，except，but，like，as well as，rather than，more than，no less than，besides，including等引起的短語，謂語動詞仍用單數(shù)形式；若主語為復(fù)數(shù)，謂語用復(fù)數(shù)形式．在本題中主語是air pollution，是單數(shù)的名詞，故謂語動詞使用單數(shù)的形式，排除B．故答案選A．

點(diǎn)評 本題考查主謂一致．主語為單數(shù)名詞或代詞，盡管后面跟有with，together with，except，but，like，as well as，rather than，more than，no less than，besides，including等引起的短語，謂語動詞仍用單數(shù)形式；若主語為復(fù)數(shù)，謂語用復(fù)數(shù)形式．
如：Mr．Green，together with his wife and children，has come to China．
Nobody but Jim and Mike was on the playground．
She，like you and Tom，is very tall．
