解析:
21 . B ?键c:連詞的辨析。 in that 因為; so long as 只要; in case 萬一; as far as 就……(而論)。句意:只要讓他以自己的方式去做,他肯定會按時完成工作。
22 . D ?键c:形容詞和副詞的辨析。選項中的四個詞似乎都有“小,少”的意思,但它們的詞性和用法各不相同。 minimum a . 最小量的; short a . 不足的; seldom ad . (不常,很少; scarce a . 稀少。句意:如果這種魚已告稀少,后代人可能就完全品嘗不到了。
23 . C 。考點:不定式用于構(gòu)成復(fù)合謂語的用法。 Something is reported ( believed , said , etc. ) to do/to have done… 是一常用結(jié)構(gòu),意為“據(jù)報道(據(jù)認(rèn)為,據(jù)說等)某事(發(fā)生)……”。該結(jié)構(gòu)中,不定式用于構(gòu)成復(fù)合謂語,表示一般情況時用簡單不定式,表示過去情況時用不定式的完成式。句意:據(jù)當(dāng)?shù)貓蠹垐蟮,那家銀行昨天在光天化日之下遭搶劫了。
24 . C 。考點:形容詞的固定搭配。關(guān)系代詞前是否用介詞、用什么介詞應(yīng)由從句中的有關(guān)詞語搭配來決定。因為該從句中與形容詞 comparable 搭配的介詞是 to (be comparable to 意為“與……可以比擬的”),故答案為 C 。句意:農(nóng)業(yè)是人類發(fā)展中的一個臺階,只有其后的機(jī)器時代可以與之相比。
25 . B ?键c:動詞詞義的辨析。 emphasizing 強(qiáng)調(diào); reinforcing 增強(qiáng),強(qiáng)化; multiplying 增多,繁殖; in creasing 增大,增多。句意:相同的因素推動工資和價格一同上升,彼此相互作用。
