否定句式：A+notas/so+原級(jí)+as+BA不如B...判斷正誤?Sheisastallerashersister.?Sheisastallashersister.???

中間的形容詞或副詞必須用原級(jí)。

As...as結(jié)構(gòu)(A+as+原級(jí)+as+B)聯(lián)想拓展①“as...as...”可以用來表示倍數(shù)。把twice、threetimes、half或

aquarter等表示倍數(shù)的詞(短語)置于第一個(gè)as之前,意為

“……是……的幾倍/幾分之幾”。Sheworksthreetimesashardasme.她用功的程度是我的三倍。②aswellas是并列連詞,意為“以及”,用來連接并列成分。當(dāng)該

短語連接并列主語時(shí)，強(qiáng)調(diào)前面的主語,故謂語動(dòng)詞在人稱

和數(shù)上與前一個(gè)主語保持一致。Theteacher
