_______ of the students in our class _______ interested in micro blogs (微博) on the Internet.

A．Two fifths; is       B．Two fifths; are      C．Two five; is        D．Two-five; are

 

【答案】

B

【解析】

試題分析：英語中一般用基數(shù)詞表示分數(shù)的分子，用序數(shù)詞表示分數(shù)的分母。當分子是一時，分數(shù)的分母用單數(shù)形式，在表示分數(shù)時，當分數(shù)的分子大于一時，分數(shù)的分母要用復數(shù)形式。根據分析可知選項CD結構有誤，當復數(shù)名詞前后分數(shù)修飾時，謂語動詞與被修飾的名詞保持一致，students是復數(shù)形式，故選B。

考點：分數(shù)表達

點評：英語分數(shù)的表達規(guī)則比較固定，學習中應牢記這些基本規(guī)則。需注意的是，由分數(shù)修飾的主語后面謂語動詞的數(shù)，和被修飾主語的單復數(shù)保持一致。

判斷正誤，正確的填 “A”，錯誤的填 “B”。
     Like many other parents , I worry that my children watch too much television. Why? First, there are
a lot of bad programmes (節(jié)目) on TV. They may copy what they see on it. Second, sitting in front of
the TV set all day is bad for their eyes. Many students wear glasses because they watch TV for long
hours. Also, watching TV too much makes children think little. I think it is very important for children to
read some books. Books will make children think more. When I say this to my children, they just do not
answer. They are too busy watching TV to answer me. So, I have decided to sell the television set.
Don't you think it is a good idea?
(     )1. From this writing we know many stu dents wear glasses because they watch too much TV.
(     )2. Two bad sides are said in the wr iting.
