答案：

1. B) 【句意】 如果突然出現(xiàn)巨大的噪音，這些動(dòng)物真的有可能受到驚嚇。

【難點(diǎn)】 該句是一個(gè)省略if的倒裝的虛擬條件句，可還原為“if there s hould be...”。

2. D) 【句意】 一點(diǎn)一點(diǎn)地，兒童就會(huì)將自己的語(yǔ)言作些必要的修改，而使之與他人的語(yǔ)言相像。

【難點(diǎn)】 as和like都可以表示“像…一樣”，但as是連詞，后跟從句，like是介詞，后跟名詞或名詞性短語(yǔ)。

3. C) 【句意】 用塑料纖維制成的衣服比用棉花、羊毛或絲綢等天然纖維制成的衣服有些優(yōu)勢(shì)。

【難點(diǎn)】 clothing是衣服、被褥的總稱(chēng)，不能用one或the one來(lái)指代。what相當(dāng)于“先行詞+that”，后邊要接從句。所以只能用that指代clothing。

4. A) 【句意】 財(cái)政部發(fā)布命令，從即日起，向政府購(gòu)買(mǎi)土地須以金、銀支付。

【難點(diǎn)】 henceforth意為“從今以后”，符合題意要求。

5. D) 【句意】 學(xué)生們期望期末考試前能有更多的復(fù)習(xí)課。

【難點(diǎn)】 動(dòng)詞expect后必須接動(dòng)詞不定式作其賓語(yǔ)，因此，只有D)為正確。
