Question

【題目】Since then the number of people taking driving Lessons 20%.

A.has increased toB.have increased to

C.has increased byD.have increased by

Answer 1

【答案】C

【解析】

考查時態(tài)、主謂一致和固定短語。句意：從那時起，上駕駛課程的人數(shù)增加了20%。根據(jù)“ since then”可知，本句為現(xiàn)在完成時，主語為the number of people，謂語動詞為單數(shù)形式。increase to “增加到”，increase by“增加了”，再結(jié)合句意。故選C項。
