參考答案：

1.A答案解析：看第2題的四個(gè)選項(xiàng)可以斷定這里指食人魚是什么樣的殺手。應(yīng)當(dāng)選擇具有“作為”含義的詞。選項(xiàng)A是正確的:作為可怕的殺手。

2.B答案解析：Killer殺手,murderer兇手。二者的區(qū)別在于前者泛指殺人,后者強(qiáng)調(diào)有預(yù)謀的行兇。故，B答案正確

3.D答案解析：Tell告訴,say說(shuō),describe描述,portray描繪。文中have been表明是被動(dòng)語(yǔ)態(tài),應(yīng)選擇過(guò)去分詞;根據(jù)上下文,這種魚已被描繪成致命的食肉動(dòng)物。選項(xiàng)D是正確的。

4.C答案解析：表示“來(lái)自于哪兒”應(yīng)用介詞from。此處意為來(lái)自圣安德魯斯大學(xué)的老師。選項(xiàng)c是正確的

5.B答案解析：解析：根據(jù)上下文：食人魚組成巨大的群體并不是為了獵取，而是為了自我保護(hù)以抵御其他的捕獵者。因此，這里應(yīng)選用具有“它們自己”含義的詞。選項(xiàng)B是正確的。

6.D答案解析：Able能夠,應(yīng)與be連用;be able能;enable使能夠;enabled是enable的過(guò)去式。根據(jù)上下文,這里講的是以前人們對(duì)食人魚的看法,應(yīng)用過(guò)去時(shí)。食人魚的群體活動(dòng)可以賦予它們合作捕獵的能力。選項(xiàng)D

7.B答案解析：從“我們發(fā)現(xiàn)……”一句看出,與以前人們的看法不同,食人魚的群體活動(dòng)只是為了保護(hù)自己。應(yīng)選擇表示與前句意義相反的轉(zhuǎn)折詞。選項(xiàng)B

8.C答案解析：食人魚會(huì)受到其他動(dòng)物的攻擊。這里列舉幾種動(dòng)物,應(yīng)用like,或such as。選項(xiàng)C是正確的。

9.D答案解析：食人魚群體活動(dòng)的目的是避免被殺戮(being killed)。Prevent sb.from doing sth.防止某人做某事，該詞通常與from連用，排除選項(xiàng)A和B。of是介詞，后跟名詞性的詞。所以，選項(xiàng)D是正確的。

10.B答案解析：由此往后連起來(lái)看,大意是食人魚的群體組合是根據(jù)所面臨的危險(xiǎn),根據(jù)水的深淺。并且,處于繁殖期的魚處于魚群的中央,以獲得保護(hù)。of后應(yīng)跟名詞性詞組,age前應(yīng)有形容詞修飾。Reproduce是動(dòng)詞,reproductive是形容詞,reproduction是名詞,reproductively是副詞。選項(xiàng)B是正確的。Reproductive age繁殖期。

11.A答案解析：把處于繁殖期的魚圍在中間的目的是為了保護(hù)它們。For是介詞,后用名詞形式。選項(xiàng)A是正確的。For protection為了保護(hù)。

12.B答案解析：把處于繁殖期的魚圍在中間的目的是為了保護(hù)它們。For是介詞,后用名詞形式。選項(xiàng)A是正確的。For protection為了保護(hù)。

13.C解析:魚群的大小組合肯定是根據(jù)可能面臨危險(xiǎn)的大小。Fate命運(yùn),destiny命運(yùn),risk危險(xiǎn),chance機(jī)會(huì)。選項(xiàng)C是正確的。

14.A答案解析：根據(jù)下一句:如果水位下降。說(shuō)明這里應(yīng)該是指水位比較高的時(shí)候。選項(xiàng)A是正確的。

15.B答案解析：For支持,against反對(duì),without沒(méi)有,towards朝、關(guān)于。根據(jù)原文,食人魚組成大的魚群作為保護(hù)以抵御捕食者。選項(xiàng)B是正確的。
