We wanted to study how students at our school spend money. In order to study this, we made some questions to ask our classmates. First, we asked our classmates how much money they spent in one month. Then we asked how much money they spent on things like drinks, music, books, movies, computer games, and other things. Our math teacher helped us make a graph of our classmates’ answers.
Then we thought it would be interesting to compare these answers with our classmates’ expenses from last year. We used their answers to make another graph for their expenses last year.
Looking at the two graphs, it is easy to compare the expenses for the two years. Some of their expenses increased, but others decreased. This was a very interesting project for us.
注：⑴ graph 图表 ⑵ expense消耗，消费

【小题1】 What did the students spend most of their money on?A．Books.B．Movies.C．Drinks and snacks.D．Computer games.【小题2】Which expense of the students’ stayed the same?A．CDs.B．Phone costs.C．Others.D．Transportation.【小题3】What does the word “decrease” mean?A．减少B．变化C．增加D．删除【小题4】What did the students spend the same money on last year?A．Books& OthersB．CDs & Movies C．Movies & BooksD．all the above【小题5】Which of the following is NOT TRUE according to the graph? A．Students spent the least money on e-mail and phone costs this year.B．Students spent the same money on movies and transportation this year.C．The expenses on e-mails and phones increased from 10% to 16% this year.D．The expenses on others decreased from 9% to 4% this year.C

(答案→)C 解析：1. Ｃ　由图可以看出第一项Drinks and snacks的长度最长比例最大，故选Ｃ。2. Ｄ　本题问的是比例一样大的。很明显今年和去年持平的是交通方式14%，故选Ｄ。3. Ａ　此题是猜词，由上句Some of their expenses increased(有的消费增加了)，可知下句说的是有些消费减少了，是个反义词，故选Ａ。4. Ａ　本题问的是去年持平的项目，看白线。不难看出是Books& Others，都是9%，故选Ａ。5. Ａ　看图中的黑色线，是others最少只占4%，故Ａ错选Ａ。

这个解释是对的
