列式计算2：
（2）李阿姨4小时做了56个玩具，照这样计算，她一天工作8小时可以做多少个？
列式计算1：
列式计算2：
（1）方法1：
（495-45×7）÷45，
=（495-315）÷45，
=180÷45，
=4（天），
方法2：
495÷45-7，
=11-4，
=7（天），
答：还要生产7天；
（2）方法1：
56÷4×8，
=14×8，
=112（个），
方法2：
8÷4×56，
=2×56，
=112（个），

If you don't go to bed early, you 3 enough sleep, then you can't think properly and can't do your work properly. You will not be clever. Some people go to bed late and get up late. This is not good 4 them. We must sleep at nine when it is dark. The dark help us 5 .When the daytime comes, we must get up. This is time for exercises. If you lack exercises, it becomes 6 . Exercises help a strong body. Exercises help the blood (血液) flow around 7 the body. This is very important. Blood takes food 8 all parts of our body, the brain (大脑) needs blood. We think 9 our brain. If we keep our body 10 and take exercises, we can think better. | ||||
