【題目】 Experiments _______ that children can be instructed in swimming at a very early age, as early as about two months.

A.are provingB.will be provedC.are provedD.have proved

【答案】D

【解析】

考查現(xiàn)在完成時態(tài)。句意:實驗證明,兒童在很小的時候就可以開始學(xué)習(xí)游泳,最早兩個月大就可以了。此處表示到現(xiàn)在為止已經(jīng)得到的證明,所以句子用現(xiàn)在完成時態(tài),且主語是Experiments,名詞復(fù)數(shù),故選D。
