        1. Every year lots of trees ________ to make our country more beautiful.
          A.is planted B.was planted
          C.a(chǎn)re plantedD.were planted
          C

          試題分析:句意:每年都要種許多樹來讓我們的國家更美麗。結(jié)合語境可知本句描述的是經(jīng)常性動作,故用一般現(xiàn)在時態(tài),主語lots of trees為復(fù)數(shù)形式,選C。
          點(diǎn)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(jìn)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)。be動詞往往根據(jù)句子的主語而有所不同,其應(yīng)用原則可以結(jié)合如下歌謠來記憶;我用am,你用are;is用在他、她、它。單數(shù)名詞用is,復(fù)數(shù)名詞全用are。
