1. remain在高中英語(yǔ)中考查四種用法,兩個(gè)固定句型.
1）vi.剩下/殘存：remain (+ 介賓/副詞)
如：Nothing remained on the road after a strong wind.
2) vi.逗留/停留：remain (+ 介賓/副詞)
如：Only a few students remained in the classroom just now.
3) vi.依舊/仍然: remain + 形容詞/名詞
如：The secret remains unknown now.
4) vi.留待/尚待：此時(shí)它有兩個(gè)固定句型如下：
固定句型一：sth/sb remain to be + 過去分詞
固定句型二：It remain to be seen + whether引導(dǎo)的主語(yǔ)從句
如：The problem remained to be solved.
It remains to be seen whether he'll come or not tomorrow.
5）最后補(bǔ)充說(shuō)明remaining的特殊用法.
remaining除了是remain的現(xiàn)在分詞/動(dòng)名詞形式外,還可以單獨(dú)做形容詞,意思是“剩下的”.
如：You should finish your remaining homework.
二、句子分析
1. 此句考查了“介詞with + 賓語(yǔ)several problems + 賓語(yǔ)補(bǔ)足語(yǔ)”結(jié)構(gòu)的用法.
如果該結(jié)構(gòu)中采用非謂語(yǔ)動(dòng)詞做賓語(yǔ)補(bǔ)足語(yǔ)的話,則考查賓語(yǔ)和賓補(bǔ)動(dòng)詞的關(guān)系.很明顯,從remain上述用法可以看出,它是一個(gè)不及物動(dòng)詞,沒有被動(dòng)語(yǔ)態(tài),即several problems和remain之間是主動(dòng)/主謂關(guān)系.而且因?yàn)橘e補(bǔ)所表示的動(dòng)作已經(jīng)發(fā)生,所以只能用現(xiàn)在分詞remaining(如果為發(fā)生,用不定式短語(yǔ)to remain...).
2. 第二個(gè)問題就很好回答了.
請(qǐng)樓主再看看remain作為“尚待/留待”解釋時(shí)的第一個(gè)固定句型.
只能說(shuō)“sth remain to be + 過去分詞”,不能說(shuō)“sth remain to do”.
所以是remain to be solved,而不是remain to solve.
