Question

As we have known from the map of the world, this is ______.

A．twice as large an island as that	B．twice as larger as that island
C．a(chǎn)s twice as that one	D．twice as a large island as that

Answer 1

A

試題分析：考查倍數(shù)：倍數(shù)+as+adj+an/a+名詞as，先是twice，然后是as +形容詞（large）an island +as…,句意：從世界地圖上我們可以看出這是那個(gè)島兩倍的島嶼。選A。
點(diǎn)評(píng)：倍數(shù)表達(dá)要牢記，倍數(shù)表達(dá)法是高中英語(yǔ)教學(xué)的重點(diǎn)，也是歷屆高考的熱點(diǎn)。當(dāng)我們要表達(dá)甲是乙的幾倍時(shí)，通常用句型來(lái)表示： “A+倍數(shù)+形容詞或副詞的比較級(jí)+than+B”，表示“A比B大（長(zhǎng)、高、寬等）多少倍”。2.“A+倍數(shù)+as+形容詞或副詞的原級(jí)+as+B”，表示“A正好是B的多少倍”。 3. “A+倍數(shù)+the size /height /length /width，+of+B”，表示“A正好是B的多少倍”。4.“……times+what+從句”。還要特別注意：as/how/so/too這幾個(gè)詞都是先加adj再加冠詞然后是名詞的搭配。
