44、意是:他们比不上狗熊,狗熊的力量、速度和爪子都能够提供很好的武器。选项A符合题意。(3)考查动词词义辨析。 become “成为”;equip “装备;配备”;pose “摆姿势”;provide “提供”。空格处所在句子的句意参考第32题,选项D符合题意。(4)考查介词词义辨析。空格处所在句子的句意是:他们甚至不能像马和斑马那样通过奔跑来保护自己。by “通过”,符合题意。(5)考查动词词组辨析。be driven to “沉浸于”;be doomed to sth. “注定”;be forced to “被迫”;lead to “导致”。空格处所在句子的句意是:如果一个类人猿试图在野外与其

45、他动物搏斗,他们注定失败并且灭绝。选项B符合题意。(6)考查动词词义辨析。bestow “赠给”,常与on或upon搭配;give “给”,常与to搭配;present “赠予”,常与with搭配;endow“天生具有,赋予”,一般用被动式与with搭配。空格处所在句子的句意是:他们天生拥有其他任何竞争对手所不具有的某种巨大的隐蔽的优势。选项D符合题意。(7)考查动词词义辨析。manage “成功做”;possess “占有”;pose“摆姿势”;oppose “反对”。空格处所在句子的句意参考第36题。选项B符合题意。(8)考查固定搭配。in the search of 是固定搭配,“在寻找

46、 的过程中”。选项B符合题意。(9)考查动词词义辨析。generate “生成,产生”;progress “进展,进步”;develop “形成,获得”;advance “前进,发展”。空格处所在句子的大意是在生存竞争中类人猿逐步形成了有效的、草地动物不具有的立体视觉和颜色辨色能力。选项C符合题意。(10)考查定语从句。先行词是efficient stereoscopic vision and a sense of color,先行词有两个,所以只能用 that。选项D符合题意。(11)考查动词词义辨析。urge “催促”;permit “允许”;ban “禁止”;cause “引起”。空格处

47、前面 the ability to see clearly at close range “能够近距离看到目标的能力”这个能力为它们研究实际问题提供条件,即“允许”它们去研究实际问题。选项B符合题意。(12)考查固定搭配。beyond the reach of “在 范围之外”。选项C符合题意。(13)考查副词词义辨析。quite是程度副词,可以用在限定词another前面,而另外三个副词则不可以。选项B符合题意。(14)考查从句引导词。本句是由so引导的一个从句,句子缺少一个引导词,该引导词充当they had to do的宾语,all符合题意。(15)考查形容词词义辨析。available

48、 “可得到的;可用的”;enough “足够的”;sufficient “充足的”;convenient意为“方便的”。空格处句子所在的句意是:然而,在空旷的野外,这种方法是行不通的。选项A符合题意。(16)考查动词词义辨析。choose“选择,挑选”;adopt“采用;采纳”;accept“接受”;take“实施;采取”。空格处所在句子的句意是:类人猿采用了唯一可行的方法。选项B符合题意。(17)考查形容词词义辨析。valuable “有价值的”;acceptable “可接受的,合意的”;possible“可能的”;able “能够的”。空格处所在句子的句意是:它们的后肢尽可能高地抬起,开

49、始直立行走。选项C符合题意。(18)考查前后逻辑。however“然而”;therefore“因此”;meanwhile“同时”;subsequently“随后”。空格处所在句子与前面的句子提到直立行走使得类人猿站不稳,并且跟其他动物相比本来速度就慢了,现在变得更慢了(It was extremely unstable and it meant that the already slow ape-man became slower still)。空格处后面提到类人猿继续坚持并且使得骨头结构开始逐渐变化,可以看出前后存在转折关系,所以however符合题意。(19)考查形容词词义辨析。be su

50、ited to sth. “适合 的”;be accustomed to “习惯于”;be familiarized with“与 相熟”;adapt to sth. “适应”。空格处所在句子的句意是:它们的骨骼渐渐适应了这种新的行走方式。选项C符合题意。(20)考查动词词义辨析。obtain “获得”;call “叫”;deserve “值得”;earn “赚得,赢得”。空格处所在句子提到由于类人猿的骨骼逐渐适应了直立行走,因此赢得了“直立人”的称号。选项D符合题意。5. 单选题( )of the grassland dwellers of the North American contin

51、ent is the antelope, or pronghorn.问题1选项A.TypicalB.The typicalC.Typical isD.While【答案】A【解析】考查倒装句。分析句子可知,这是一个倒装句,正常的语序是:the North American antelope,or pronghorn is typical of the grassland dwellers of the continent。选项A符合题意。句意:美洲羚羊,又叫叉角羚,是北美大陆典型的草原动物。6. 单选题The purpose of the lecture was to( )the masses

52、of the United States with the elementary problems of Latin America.问题1选项A.informB.acquaintC.instructD.announce【答案】B【解析】考查固定搭配。inform “通知”;acquaint “了解”;instruct “通知,指导”;announce “宣布”。句意:讲座的目的是为了使美国大众了解拉丁美洲的基本问题。acquaint sb. with sth. “使某人了解某事”。选项B符合题意。7. 单选题Advertising is distinguished from other fo

55、aving originally cultivatedD.Although it originally cultivated【答案】A【解析】考查过去分词的用法。句子的主语时 the banana,从四个选项可知 cultivate 是一个关键词,其与 the banana的关系是被动关系,所以应该用被动语态,选项C与D可以排除。主句中用的时态是 was 过去时,因此可以排除选项B。选项A符合题意。10. 单选题The( ) prevents the people in the two neighboring nations from living in peace.问题1选项A.brevit

56、yB.amenityC.enmityD.fidelity【答案】C【解析】考查名词词义辨析。brevity “简洁”;amenity “舒适,愉悦”;enmity “敌意,憎恨”;fidelity “忠诚”。题干中提到有一种东西会阻止两邻国友好相处,这种东西很明显是enmity,选项C符合题意。11. 单选题How many times did the clock( ) ?问题1选项A.hitB.knockC.beatD.strike【答案】D【解析】考查动词的固定搭配。strike可以用来表示“敲打钟表”,其他的词则不行,所以选项D符合题意。12. 单选题Although he is in

59、选题( )this, everything is order.问题1选项A.ExceptB.BesidesC.Except forD.but【答案】C【解析】考查语法知识。这个题主要考查except 和except for 的用法。二者均表示“除 以外”。Except 后面接的词与主语一般是同类型;except for 后接的词与句子主语不是同类。从题目中可以分析出前后不是同一种类的事物,所以选项C符合题意。15. 单选题Prof. Flynn found no students in the lecture hall when he arrived. Only then did he rea

60、lize that he came( ) early.问题1选项A.too muchB.much tooC.so muchD.much so【答案】B【解析】考查词组辨析。Too much “太多”,为形容词短语,修饰名词;much too “太 ,非常 ”,为副词短语,修饰形容词或者副词;so much “这么”,副词短语,放在动词后修饰动词,或者作形容词短语修饰名词;mush so 这个短语不存在。句意:Flynn教授到达阶梯教室时没有看见一个学生。直到那时他才意识到他来得太早了。选项B符合题意。16. 单选题Many young people take ( )radios to the
