19、s D. Although（分数：1.00）A.B.C.D.解析：考点 考查让步状语从句。四个选项中，B和C不合理。A项的in spite of是复合介词，后应接名词。如果状语从句中的主语和主句中的主语一致，就可以省略状语从句中的主语和谓语be，从而使句子更加简洁明了。在这句话中，从句中的主语也是corn，因此其主语corn和谓语is可以省略，故D为正确答案。4.Advertising media like direct mail, radio, television and newspapers _ to increase the sales of industrial products.-

22、ed that we _ as attentive as possible when we visit the museum. A. are B. shall be C. be D. were（分数：1.00）A.B.C.D.解析：考点 考查虚拟语气。recommend，command，suggest等词后接的宾语从句中应用虚拟语气，即(should)+动词原形，由此可知C为正确答案。8.We will be losing money this year unless that new economic plan of yours _. miracle.

25、独接ones own。根据句意可知选C。11._ in the past, at the moment it is a favorite choice for wedding gown. A. Unpopular has as white been B. White has been as unpopular C. Unpopular has been as white D. Unpopular as white has been（分数：1.00）A.B.C.D.解析：考点 考查倒装结构。动词、形容词、名词+as/though的让步状语从句，往往使用半倒装结构。如：Beautiful as s

26、he is，she is foolish由此可知D为正确答案。12.The eldest child is thoroughly _ because they always give him whatever he wants.

29、to me. A. worthy B. valuable C. valueless D. priceless（分数：1.00）A.B.C.D.解析：考点 考查形容词词义辨析。worthy意为“值得的”，一般作表语；valueless意为“微不足道的”；priceless意为“无价的”，都与句子意思不符。valuable意为“有用的，重大的”，为正确答案，故选B。16.If he hadnt stood under the ladder to catch you when you fell, you _ here now. A. wouldnt be smiling B. wont smile

30、C. couldnt have smiled D. didnt smile（分数：1.00）A.B.C.D.解析：考点 考查虚拟语气。这句话是错综时间条件句，条件从句的动词时态可以和主句的动词时态不一致。从句和主句要根据各自所发生的时间选用符合具体时间的虚拟语气形式。由if从句中的when you fell可知，从句是对过去事实的虚拟；由主句中的now可知，主句是对现在事实的虚拟，因此谓语动词应为wouldnt be smiling。故A为正确答案。17.While being questioned on the court, the man denied _ the old ladys ne

33、way意为“某种方式”，也是名词。根据句意可知，本题应该用副词somehow，故选B。20.We feel it is high time that the Government _ something to check the inflation. A. did B. do C. should do D. would do（分数：1.00）A.B.C.D.解析：考点 考查虚拟语气。It is high time that后面接一般过去时表示虚拟语气，意为“该到的时候了”，故A为正确答案。21.She put an extra blanket over the baby for fear th

35、ing canceled D. having been canceled（分数：1.00）A.B.C.D.解析：考点 考查独立主格结构。句子中间使用的是逗号，故该句的前半句应使用独立结构，由于动作发生在过去，所以应该用被动语态的完成时形式，故D为正确答案。23.Clothing made of plastic fibers has certain advantages over _ made of natural fibers like cotton, wool, or silk. A. one B. the one C. that D. what（分数：1.00）A.B.C.D.解析：考点

36、考查代词的用法。这句话的主干是一个比较结构，前后两个被比较的成分是平行的。clothing是衣服、被褥的总称，为不可数名词，不能用one或the one来指代；what相当于“先行词+that”，后面要接从句。因此只能用that指代clothing，故本题应该选C。24.The _ of beer and alcohol in New Zealand is very high. A. consumption B. use C. drink D. absorption（分数：1.00）A.B.C.D.解析：考点 考查名词词义辨析。consumption意为“消耗，消费；消费量”；use意为“使用

39、”，后接名词。故选D。27.Having had her as a professor and adviser, I can tell you that she is an _ force who pushes her students to excel far beyond their own expectations.
