衛生類復習指導:詞匯精講The substance
1. The substance can be added to gasoline to accelerate (B級)the speed of automobiles.
A) quicken B)shorten C) loosen D) enlarge
參考答案：A
答案解析：accelerate v.加速，促進，所以A(加快)是答案。shorten v.縮短，(使)變短；loosen v.解開，放松，松開；enlarge v.擴大，放大；詞綴-en通常加在某些形容詞的前面或后面，使其變成相應的動詞，該詞綴的含義是“使變得更加..”，如：enlarge就是“使變得更大/擴大”。
2. We should never content (B級)ourselves with only a little knowledge.
A) convince B)satisfy C) comfort D) benefit
參考答案：B
答案解析：根據句意(我們切不可…僅僅有一點點知識。)判斷B(使滿足)是答案。convince vt.使確信，使信服；benefit n.利益，好處vt.有益于，有助于；comfort n.安慰，舒適vt.安慰，使(痛苦等)緩和。
3. We should contemplated (B級)the problem from all sides.
A) deliberated B)thought C) described D) designed
參考答案：A
答案解析：借助搭配結構“…問題”排除B(think后通常帶賓語從句或帶介詞)和D(D的詞義為“設計”，因此D與“問題”搭配不合理)。根據句意(我們應該…問題的各個方面)判斷A(仔細考慮)最合適。
4. His health had deteriorated (B級)while he was in prison.
A) became better B)became worse C) became stronger D) became weaker
參考答案：B
答案解析：借助搭配“健康…”，排除C和D(strong(強)和 weak(弱)都不能與“health/健康”搭配使用，只有“身體”才說強弱)，再借助句意(在監獄服刑期間他的健康…)判斷B(變得更糟糕)最合理。deteriorate v.(使)惡化 。
5. How can we reduce the risk of cancer?
A) cut in B) cut down C) cut off D) cut out
參考答案：B
答案解析：劃線詞是基本詞匯，其含義是“減少”，被選項是由同一動詞組成的短語結構(提示：可以借助短語結構中某個單詞的詞義來推測短語可能具有的含義)，從“減少”這個詞義來看，B最可能是答案(down 有“向下”的含義)。該句的大意是“我們怎樣才能降低癌癥的風險?”。cut in是“插話”；cut down是“減少，削減”；cut off是“中斷，切斷”；cut out是“切去，刪除”。
6. The steadily rising cost of labor on the waterfront has greatly increased the cost of shipping cargo by water.
A) continuously B) quickly C) excessively D) exceptionally
參考答案：A
答案解析：劃線詞steadily是“穩定地；不斷地”，該詞與A(不斷地，連續地)是近義詞。excessively是“過度地”；exceptionally是“例外地，異常地”，quickly是“很快地” 。該句的大意是“勞動力成本的持續上升已經大大地增加了通過水路運輸貨物的費用。”
7. His new girlfriend had omitted (B級)to tell him that she was married.
A)failed B) deleted C) refused D) rejected
參考答案：A
答案解析：借助劃線詞的搭配結構特點—帶不定式結構，判斷A(fail to do sth./沒有…)和 C(refuse to do sth./拒絕做…)可能成為答案。從句意義上看“他新交的女友沒有告訴他她結婚了。”更通順，所以A是答案。omit是“遺漏，忽略，忘記”，delete(刪去)和reject(拒絕，抵制)都是及物動詞，后面必須帶賓語。
8. If you want my advice，you should revise (B級)your plan for the trip to Beijing.
A) change B)exchange C) enlarge D) encourage
參考答案：A
答案解析：借助劃線詞所在的搭配結構“…你的計劃” 判斷A(改變)最合適。 該句句意是“如果你接受我的建議，你應該改變你北京之行的計劃。” exchange是“互換，交流，兌換”；enlarge是“擴大，擴充”；encourage是“鼓勵”，revise“修訂，改變”。
