The Low-carbon Economic
Nowadays,with more and more serious problems such as the increasing global temperture,the melting ice and the rising sea-levering,people are recognizing the important of developing the low-carbon economic now.
There are many ways we can do to reach the loe-carbon economic.Fristly,discovering others fuels which is more clean and more green to instead of the using of carbon.Secondly, we should have the save-energy conscious and do something which we can make,for instance,using the bus ranther than car when you go out,re-use the thing that can be recycle used,recing the use of plastic bags.Last but not least,we should plant more trees or other greenplants,in which way we can not only improve the environment,but also can make our home more beauty.
In my opnion, the most important thing to reach the low-carbon economic is everyone must try their best do what they can do for it.Once everyone have the sence of low-carbon economic and have the action by themselves ,it will be earlier to reach it.

一、填空
這部分內容主要考察的是除法的知識點:
除法四則運算之一,已知兩個因數的積與其中一個非零因數,求另一個因數的運算是除法。 兩個數相除又叫做兩個數的比。若ab=c(b≠0),用積數c和因數b來求另一個因數a的運算就是除法,寫作c÷b,讀作c除以b(或b除c)。其中,c叫做被除數,b叫做除數,運算的結果a叫做商。
被除數擴大(縮小)n倍,除數不變,商也相應的擴大(縮小)n倍。除數擴大(縮小)n倍,被除數不變,商相應的縮小(擴大)n倍。
被除數連續除以兩個除數,等於除以這兩個除數之積。有時可以根據除法的性質來進行簡便運算。如:300÷25÷4=300÷(25×4)除以一個數就=這個數的倒數。
