⑤large quantities of water are badly needed here.
這里急需大量水。
【溫馨提示】 a quantity of后同樣可接不可數名詞或可數名詞的復數形式。但當它作主語時謂語動詞一般根據其所修飾的名詞而定，而quantities of作主語時，不論其后的名詞為可數或不可數，謂語動詞都用復數。
[即境活用]
1.(XX年高考福建卷)—why does the lake smell terrible?
—because large quantities of water________.
a.have polluted
b.is being polluted
c.has been polluted
d.have been polluted
解析：選d。本題考查時態、語態及主謂一致問題。句意：——這湖水怎么這么難聞？——因為大量的水已經被污染了。water與pollute為被動關系，故排除a項；b項表示“正被污染”，故排除；large quantities of后加名詞，謂語動詞應與quantities保持一致，故排除c項，答案為d項。
2oppose vt. 反對；反抗；與(某人)較量
(回歸課本p27)on the other hand，there are those，like george hambley，who are opposed to this view and believe that we should not worry about high levels of carbon dioxide in the air.
在另一方面，還有一些人，像科學家喬治•漢布利，反對上面的觀點，他們認為我們不必擔心空氣中會有高含量的二氧化碳。
