【正文】 2)both…and…既…也…,(兩者)都… A、both…and…構(gòu)成的詞組作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞用復(fù)數(shù)。 You can’t speak both German and English. Both my father and my mother aren’t doctors. 3)neither…nor…:既不…也不… neither…nor…連接兩個(gè)并列主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞靠近哪個(gè)主語(yǔ)就與哪個(gè)主語(yǔ)保持 “人稱”和 “數(shù)”的一致，即采取就近原則。 Not only the mother but also the children are ill. ?。篵ut, however, yet, still,while等。 1)or:或、否則 A:基本用法 or 表示 “或” 的意思，使用于兩者之中選擇一個(gè)的時(shí)候。 不是…就是…。 Either you or I am right. Does either she or they like English? B. 由either…or…引導(dǎo)的否定句是完全否定。 He is not at school today, for he has a bad cold. It was late, so I went home. ?。篵efore, after, when, while, as, till, until, since, as soon as等。while從句謂語(yǔ)動(dòng)詞只能是延續(xù)性動(dòng)詞，側(cè)重主從句動(dòng)作同時(shí)發(fā)生。 When I came in, my father was cooking. I came in when/while my father was cooking. He sang as he walked. 2)until用法：當(dāng)主句謂語(yǔ)動(dòng)詞是延續(xù)性動(dòng)詞時(shí)，主從句都用肯定式，譯為“直到……為止”。
