问题 选择题

下面说法不正确的是[ ]

A.三角形的面积一定,底和高成反比例

B.长方形的周长一定,长和宽不成比例

C.订阅《少年报》的份数和总钱数成正比例 

D.因为圆周长C= πd,所以π与d成反比例

答案

答案:D

解:A、三角形的底×高=面积(一定),是乘积一定,成反比例,此句正确;

B、长方形的长+宽=周长(一定),是和一定,不是乘积或比值一定,不成比例,此句正确;C、订《少年报》的总价÷份数=单价(一定),是比值一定,成正比例,此句正确;D、圆周长C=πd,但π是定量,不随着d的变化而变化,所有π与d不成比例,原句错误;故选:D.

完形填空
My life is always full of sadness and little joy. However, no matter(无论) what happens, I can always face it bravely.
Last year,  I couldn’t believe the        that I could enter the only key high school in my hometown. Then I rushed to my home and told my parents. But my father didn’t seem as       as I was. He just kept smoking without saying a word and my mother put her head down and couldn’t help      .
I knew very well what my family was     ___ . My mum had been ill in bed for 2 years. We lived a hard life and I couldn’t continue my schooling. I felt so upset(心烦意乱) but I could say        to my parents. I decided to help my father with his work       my family.
To my surprise, things completely changed         the beginning of the new term. My head teacher came to my family        some money, which was raised by my schoolmates. He encouraged me, “Always have a dream.” With tears in my eyes, I stepped into the key high school.
I have been studying hard since I entered the high school. No matter when I meet difficulties, I always         my teacher and schoolmates. I have a college dream and I must work hard for it, no matter how      life is. Just as a great man says, “When one door shuts, another opens in life.”
