用法辨析

adv. (副詞)

• as用作副詞時(shí)主要用來(lái)表示比較,意思是“像…一樣；如同”。可以單獨(dú)使用，但更多的是用在as...as結(jié)構(gòu)中，其中第一個(gè)as是副詞，其后可接形容詞或副詞,也可接其他成分，as前可有狀語(yǔ)。第二個(gè)as可以是介詞,也可以是連詞。as用作副詞時(shí)還可以指事物以同樣的方式發(fā)生,意思是“和…一樣”。
• as...as結(jié)構(gòu)多用于肯定式，偶爾也可用于否定式。表示同樣意思的否定式多用so...as。as...as結(jié)構(gòu)用于否定句時(shí)多用于口語(yǔ)，側(cè)重“像…一樣”；so...as結(jié)構(gòu)則多用于書(shū)面語(yǔ)，側(cè)重“像…那樣”。
• as...as結(jié)構(gòu)表示的是同級(jí)比較，第一個(gè)as后的形容詞或副詞不可用比較級(jí)，必須用原級(jí)，比較的對(duì)象亦須屬同類(lèi)。
• as...as結(jié)構(gòu)表示數(shù)量或程度時(shí)，可用于“as much+(不可數(shù)名詞+) as”或“as many+(可數(shù)名詞復(fù)數(shù)+) as”結(jié)構(gòu)。
• 修飾as...as結(jié)構(gòu)的常見(jiàn)詞語(yǔ)有nearly,almost,just,exactly,half,quite,表示倍數(shù)或次數(shù)的形容詞，“數(shù)詞+times”等。這些修飾語(yǔ)都放在as...as結(jié)構(gòu)之前。
• 使用as...as結(jié)構(gòu)時(shí)，若第一個(gè)as后的名詞是單數(shù)可數(shù)名詞并有形容詞修飾，則應(yīng)使用“as+ adj.+ a/an+ n. ”結(jié)構(gòu)，即不定冠詞應(yīng)位于形容詞和名詞之間。第二個(gè)as后面的名詞或代詞的格不同，意思也不同。
• as...as結(jié)構(gòu)中后一個(gè)as用作連詞時(shí)引導(dǎo)的從句常為省略句，省略從句中的動(dòng)詞可使主句的意義得到加強(qiáng)；反之，重復(fù)從句中的動(dòng)詞則可使從句的意義得到強(qiáng)調(diào)。
• 使用as...as結(jié)構(gòu)時(shí)，在一定的上下文中可以省去其中的一個(gè)。
