小題1:根據(jù)時(shí)間狀語(yǔ)可知本句描述的是過(guò)去的動(dòng)作，故用一般過(guò)去時(shí)態(tài).主語(yǔ)是單數(shù)，故謂語(yǔ)動(dòng)詞用單數(shù)。
小題2:根據(jù)時(shí)間狀語(yǔ)Since then,可知本句描述的是一直持續(xù)到現(xiàn)在的動(dòng)作，故用現(xiàn)在完成時(shí)態(tài)。
小題3:decide后面一般接帶to的動(dòng)詞不定式作賓語(yǔ)。
小題4:聯(lián)系前一句，可知本句描述的是過(guò)去發(fā)生的動(dòng)作，故用一般過(guò)去時(shí)態(tài)。
小題5:句意：他被稱(chēng)為“雜交水稻之父”。本句描述的是客觀性事實(shí)，故用一般現(xiàn)在時(shí)態(tài)。主語(yǔ)是動(dòng)作對(duì)象，故用被動(dòng)語(yǔ)態(tài)。
小題6:本句描述的是客觀性事實(shí)，故用一般現(xiàn)在時(shí)態(tài)。主語(yǔ)he是單數(shù)第三人稱(chēng)，故謂語(yǔ)動(dòng)詞用單數(shù)。
