【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學(xué)會游泳，最早兩個月就可以了。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。
