参考答案

1.A本题考查祈使句型：

【应试指导】句意：Mary，到这里来，其余的人待在原处。根据句子的结构可判断出这是个祈使句。所以要用动词原形开头。Mary在句中不是

主语，而是“呼语”。

2.Dapplyto应用；applyfor申请

3.C

4.Bsetout意为“出发，动身”。

5.A本句考查两个并列句之间的连接的词。题干的意思是：“气球能够浮在空气中正如船能够浮在海面上一样。”在四个选项中，只有A项的justas有“正如，犹如”的意思。故选A。

6.B解析：cuts“裁减”；shortages“短缺”；weaknesses“弱点”；imports“进口”，故正确选项为B。

7.C解析：句子的前半部分是主语从句，主语从句中的谓语动词时态应根据句意而定。

8.C

9.D解析：which修饰非限定性定语从句，指代前边一句话。本题涉及句法知识——简单句、并列句和复合句。例如：Hehastwodaughters.Theyaredoctors.(简单句)Hehastwodaughtersandtheyaredoctors.(并列句)Hehastwodaughters,whoaredoctors．(复合句)

14.B

15.D

16.B

17.B解析：encourage：鼓励、鼓舞；discourage：使泄气；prevent：阻止；ask：要求。根据句意只有选B。

18.B考查反义疑问句。原句应是：youwouldthinkhehadhaveforgotten…反义疑问句的规则是陈述部分是肯定式，疑问部分应是否定式。Wouldthink表示推测，疑问部分也应选择would。选项B是正确的。【句子大意】你难道还认为他已经忘掉了，是吗?

19.C

20.C解析：much用在句中修饰比较级better。

21.【提示】本题立足于日常表达。平日里，人们可用不同的说法表达相同的意思，因此此题比较灵活，答案不唯一，符合题意和El语表达方式即可。1.【答案】WhatcanIdoforyou/CanIhelpyou【解题指要】根据常识，当顾客进到店里，店员通常会问他们是否需要帮助，因此填入WhatcanIdoforyou/CanIhelpyou。2.【答案】Whatsize，please【解题指要】根据上下文，顾客说想买一双皮鞋，以及随后告知店员自己的鞋码，可以得知此处店员需要了解顾客的鞋码，因此填人Whatsize，please。3.【答案】Certainly/Yes，ofcourse【解题指要】根据上下文及中文提示，得知此处顾客询问是否可以试穿鞋，店员需要做出肯定的回答，因此此空填入Certainly/Yes，ofcourse。4.【答案】Howmuchisit【解题指要】根据上下文，顾客说要买下这双鞋以及下文中店员告知鞋的价钱，可以得知此空是顾客询问鞋的价格，因此此空填入Howmuchisit。5.【答案】Here’syourcharge，fiveYuan【解题指要】根据常识以及中文提示，可以得知此时店员为顾客找零，因此该空填入Here’syourcharge，fiveYuan。【参考译文】Shop-assistant：您有什么需要?Customer：我想买双鞋。Shop-assistant：请问您穿多大码的鞋?Customer：我穿40号。Shop-assistant：好的，给您。Customer：我可以试穿吗?Shop-assistant：当然可以的。Customer：我就要这双了。多少钱?Shop-assistant：45元，先生。Customer：这是50元，给您。Shop-assistant：谢谢您，这是找您的零钱，5元。再见，先生。Customer：再见。

36.C

37.D解析：A选项advice，的意思是“忠告”，B选项experience的意思是“经验”，C选项quality的意思是“质量”，D选项service的意思是“服务”。这篇文章试图通过讲述发生在一位游客身上的不寻常的故事，来揭示迪斯尼乐园急游客所急、想游客所想的服务理念。最后一段对全文内容作了小结：“这种优质的服务不在于服务手册，而在于关心他人——和鼓励以及仿效认真为游客服务的态度的文化”。

38.D解析：本题为句子结构题。句中出现了though，此时的though出现在句尾，并非作为连词，而是副词，因此全句还需连词but来联系逗号前后两部分。句子大意为：他给了我一份工作，尽管不是做摄影师，却是做模特。

39.B解析：这里是说假树在某种条件下是看不出来的。所以，应当选择表示否定的词。选项B是正确的。
