jackiehuhu

有两道语法题不太懂，虽然前边有解释过。能不能讲详细一点啊？

?39. The main advertising media include direct mail, radio, television, magazine, and

       A                   B                          C

newspaper.

       D

??40. While studying the chemistry of human body, Dr. Rosalyn Yalow won a Nobel Prize for the

A B

research she conducted on the role of hormones.

                            C           D

都是考的名词单复数问题，有个原则是单数可数名词不能单独存在，也就是单数可数名词必须有限定词修饰，比如冠词，


39、newspaper和magazine都可数，要用复数


40、body是单数可数名词，所以这里前面要加the, 即the human body

谢谢，不过为什么magazine 没有限定词呢？


95.10的题目好象也有考类似问题的，


有三题不太明白：

??26.The strength, size, and surefootedness of the Hama make it as excellent beast of burden in mountainous regions today as it was in the past.

??35. In the United States, Maryland ranks second only to Virginia as a oyster-producing state.

??37. Algae have been an extremely important link in the food chain after the beginning of life on Earth as we know it.

26题中如果按原则应该加a. 但为什么35中又不对呢？

以后还会做很多题，可能会不断的问哦，谢谢！
