词汇学习5：
　　1. A　appalling表示条件之差使人感到吃惊。dreadful有类似的意义。如：My financial situation is dreadful.此句改用appalling也是可以的。Bad, unpleasant和poor都可以跟condition搭配。因此可以说：They have been living under bad conditions for two years. They have been living under unpleasant conditions for two years. They have been living under poor conditions for two years.注意：appalling conditions蕴涵bad（或unpleasant或poor）conditions.但反向的蕴涵是不成立的。用句通俗的话说，是appalling conditions必定是bad（或unpleasant或poor）conditions,但，是bad（或unpleasant或poor）conditions未必都是appalling conditions.也就是说，appalling跟bad, unpleasant和poor在意义上存在着明显的差别。注意：如果用bad或poor替换appalling,生成的都是错误的句子。
　　2. B　anyhow的一种意思是：不管其他句子所说的，本命题为真。可以看出，该词用在该句中非常合适，因为I wasn't qualified for the job really是“不管其他句子所说的”，I got it这个命题是真的。又如：I am coming anyhow, no matter what others say.其中的no matter what others say是说：不管其他人怎么说。I am coming这个命题是真的。Anyway在绝多数情况中表达的意义跟anyhow都相同，因而二者常可替换。Anyhow有一种意思是后面所说的支持前面所说的，在这一种意思上，它等于anyhow可由besides替换。但练习题中的anyhow不是这个意思。anyhow也可用来结束会话，这也是well的一个功能。如：Anyhow, thanks a lot. Bye bye.但练习题中的anyhow不是用来结束会话的，因而不能由well替换。
　　3. C　attain有通过努力取得了某种东西或达到某种状态的意思。如：He attained the position of minister. They were unable to attain their objectives. achieve的意思是通过努力取得或达到某种目标，意思跟attain很接近，因而可由后者替换。reached也有“达到”的意思，但它本身并不含“需要通过努力”，因而它不可替代achieved.下面举一个reach用法的例子：The process of political change in South Africa has reached the stage where it is irreversible. reap是“收获，获得”的意思。The painting depicted a group of peasants reaping a harvest of fruits and vegetables. You'll soon begin to reap the benefits of being fitter. take也有“获得，取得”的意思，但它不能跟success搭配。
　　4. D　capability:能力，力量。又如：Now we have the capability to defending our country, all thanks to our own efforts. The country has the capability to defeat any aggressor. ability:能力，本领。From each according to his abilities, to each according to his work. ability和capability在意义上有相同的一面，因而在一定语境中可以互换。可以看出，ability和capability在搭配上是有差别的，前者只可跟to搭配，但后者既可跟to又可跟of搭配。二者的形容词分别是able和capable: I ought to be able to live on my salary. She was perfectly capable of taking care of herself.注意：capable只能跟of而不能跟to搭配。不难看出，词的意义不决定句法结构。strength:力量；优点。Their military strength has gone down because their air force has proved to be an effective force.此句中的strength可由capacity替代而不改变句子的意义。possibility:可能性。
　　5. A　in conjunction with:共同。together with具有相同的意思，用together代入后，所生成的也是一个在语法上正确的句子。in succession:接连发生，不跟with，如：He had missed five dinners in succession. in alliance with:结盟。They are now in a position to govern the state in alliance with either the Free Democrats or the Green Party. in connection with:在……一起；相关。13 men were questioned in connection with the murder.
　　6. B　credible:可信的。convincing:可信的。That is the least convincing excuse that you could offer. convincing可替换credible而不改变句子的意义。workable:可行的，行得通的。Your plan is workable. practical:实际的，现实的。He is weak in practical matters. reliable:靠得住的。John is a reliable man.
　　7. C　diligent:勤奋的，努力的。hardworking:勤奋的，努力的。Jack was hardworking and energetic. ambitious:雄心勃勃的；有野心的。Chris is so ambitious, so determined to do it all. lazy:懒惰的。I was too lazy to read music. clever:聪明的。She is beautiful and clever.
　　8. D　diverse:多种多样的；不同的。varied:多种多样的；不同的。It is important that your diet is varied and balanced. colorful:多色的；绚丽的。People in this small town wear colorful clothes. attractive:迷人的；吸引人的。She is both attractive and intelligent. flexible:灵活的。My schedule is flexible.
　　9. A　faulty:有错误的；模棱两可的。wrong:有错误的；有毛病的。Cheating is always wrong. ambiguous:歧义的；模棱两可的。This sentence is ambiguous. unclear:不清楚。His itinerary is still unclear. unbelievable:不可信的。I find it unbelievable that people can accept this sort of behavior.
　　10. B　gorgeous:好极了；美丽的。lovely:可爱的；美丽的。The girl is lovely. ridiculous:可笑的。It was an absolutely ridiculous decision. magnificent:壮丽的；宏伟的。There is a magnificent country house near the river. peculiar:奇特的；奇怪的。This house is peculiar in lots of ways.这些词都可替换，所生成的句子语法上都是正确的。相比之下，lovely最接近gorgeous.
　　11. C　persist:坚持；持续。continue:持续。She continued the work day after day. insist:坚持；坚持主张。My family insisted that I should not give in, but stay and fight. persevere:坚持。Despite the failure of his early experiments, the scientist persevered in his research. resist:反抗；顶住。The nation was able to resist the invasion. Insist和persist在意义上并不完全相同。insist缺乏“持续”这个义项。persevere也缺少“持续”这个义项。因此，正确的选择是continue.“坚持”与“持续”在意义上似乎很接近，但在语义上的判别是很明显的。“坚持”至少要求有生命的东西作主语，但“持续”就没有这个要求。
　　12. D　regulate:调整；控制。control:控制。She also had a temper, but she controlled it. fight:搏斗；战斗。More units to fight forest fires are planned. abolish:废除。The whole system should be abolished. remove:除去；消除。Most of her fears have been removed.
　　13. A　scatter:分散；散布；消散。separate:分散；分离。We didn't separate until nightfall. flee:逃走；消失。The robbers tried to flee, but they were caught. depart:离开；出发。We are ready to depart. spread:展开；散布。The rumour quickly spread through the village. spread与scatter有相同的义项－“散布”。但此处只能是“分散”的意思。
　　14. B　standpoint:立场；观点。point of view:观点；看法。The novel is shown from the girl's point of view. position:位置；立场。The union may shift its position on the question. knowledge:知识。To my knowledge, he owns three houses, and he may own more. opinion:看法；意见。In my opinion, this book is the best book on the subject.虽然position也有“立场”的意思，但不能说from my position.同样地我们也不能说from my opinion.
　　15. C　touching:动人的；感人的。moving:动人的；感人的。The beggar told her such a moving story that she almost wept. inspiring:鼓舞人惦的。He made an inspiring speech. boring:令人厌烦的。Not only are mothers not paid but also most of their boring work is unnoticed. frightening:吓人的。He gave us a frightening, but believable account of his childhood.
