问题 单项选择题

赵先生34岁,钱女士30岁,一天,他们碰上了赵先生的三个邻居,钱女士问起了他们的年龄,赵先生说:他们三人的年龄各不相同,三人的年龄之积是2450,三人的年龄之和是我俩年龄之和。问三个邻居中年龄最大的是多少岁

A.42
B.45
C.49
D.50

答案

参考答案:C

解析:解析:2450=2×5×5×7×7,A、B两项不是2450的因数,可以直接排除;
若年龄最大的为49岁,则剩余两个人的年龄之和为64-49=15,年龄之积为50,则正好一个为10岁,一个为5岁,C项满足题意;
若年龄最大的为50岁,则剩余两个人的年龄之和为64-50=14,年龄之积为49,此时只能两个都为7岁,这与三人年龄各不相同矛盾,排除D项。

Do your parents ever say, “act like a lady” or “be a gentleman” to you? But in the eyes of today’s teenagers(青少年), what should a lady or a gentleman be like? Let’s take a look.

What is a gentleman? The girls have their ideas:

Huang Xiaoyu of Guizhou: A gentleman doesn’t always get angry(生气的). He wants others to be well and happy. He is always ready to help. There is a boy in my class and I think he is a gentleman. If I don’t do well in the English exam, he will say, “You will do better next time.” That makes me feel happy.

Chen Tingting of Shenzhen: A gentleman always says, “Ladies first” When students clean up the classroom, he does the heavy work. He lets girls go into rooms first. There are no gentlemen in my class. When there is something to eat, the boys in my class always get them before girls!

What is a lady? Boys tell us what they think a lady is:

Wu Yifan of Dalian: A lady is quiet and kind, but she’s not shy(害羞) and she can talk about her ideas in front of others. To me, Dong Jie, a film star, is a lady. She is pretty and kind. She does a lot for others.

Wang Lichao of Tianjin: A lady is not just beautiful but clever. She never says bad words. She is quiet and kind to others. I don’t think there is a lady in my class. Most of the girls are “wild beauties”, I think.
