（A）
Have you ever been ill? When you are ill, you must be unhappy because your body becomes hot, and there are pains all over your body. You don’t want to work, you stay in bed, feeling very sad.
What makes us ill? It is germs (细菌). Germs are everywhere. They are very small and you can’t find them with your eyes, but you can see them with a microscope. They are very very small and there could be hundreds of them on a very small thing.
Germs are always found in dirty water. When we look at dirty water under the microscope, we shall see them in it. So your father and mother will not let you drink dirty water.
Germs aren’t found only in water. They are found in air and dust. If you cut your finger, if some of the dust from the floor goes into the cut (割开处), some of the germs would go into your finger. Your finger would become big and red, and you will have much pain in it. Sometimes the germs would go into all of your body, and you would have pain everywhere.

（B）
Do you get enough sleep? With so much homework ，it's often difficult to get the rest you need. But you need to try，because sleep keeps you healthy and it stops you getting fat.
Recently，a group of US scientists did a study (调查) of kids aged between 8 and 13. The study found that if kids sleep for just one extra (额外的) hour each day, the chance of their getting fat is cut by about 30 percent .
Why? When people don't get enough sleep, they become tired. When they are tired, they don't exercise enough. Also，kids like snacks: If they are awake (醒着的) an extra hour or two each day，they have more time to eat snacks or other unhealthy foods.
So，how much sleep should you get? Scientists suggest 10 to 11 hours a night for kids aged 5 to 12. For older kids, eight to nine hours will do.
6.How many reasons are given why people might get fat without enough sleep?
A. 3.
B. 2.
C. 1
D. None.
7.If you are under 10，how long do the scientists advice you to sleep?
A. 10 to 11 hours.
B. 8 to 9 hours.
C. 8 to 13 hours.
D. As long as possible.
8.Where was the study done by the scientists?
A. In China. B In Britain. C. In America. D. In Japan.
9.What does" eight to nine hours will do" mean?
A.Eight to nine hours' sleep will be good and enough.
B Eight to nine hours' sleep will be too long.
C. Eight to nine hours' sleep will help get fat.
D. Eight to nine hours' sleep will help eat snacks and unhealthy foods.
10. What does the passage talk about?
A. How to get long sleep.
B How to keep fat.
C. Enough sleep makes people healthy and slim (苗条)
D. Long sleep makes people healthy and slim.
（C）
Do teenagers in small villages do chores at home? How about the teenagers in big cities?
Here is a survey. We asked 4,000 teenagers in China several questions. Half of them come from big cities like Beijing, Shanghai and Guangzhou. The others are from small villages. We made a diagram of the result of our survey. Let’s have a look at it.We found out that teenagers from small villages do more chores than those from big cities. Maybe it is because they
live a harder life. Our advice to parents in big cities is that parents should give their children some chores to do. Doing chores teaches teenagers to take

沪科版八年级数学下知识点总结 二次根式知识点： 知识点一：二次根式的概念 形如（）的式子叫做二次根式。 注：在二次根式中，被开放数可以是数，也可以是单项式、多项式、分式等代数式，但 必须注意：因为负数没有平方根，所以是为二次根式的前提条件，如，，等是二次根式，而，等都不是二次根式。 知识点二：取值范围 1. 二次根式有意义的条件：由二次根式的意义可知，当a≧0时，有意义，是二次根式，所以要使二次根式有意义，只要使被开方数大于或等于零即可。 2. 二次根式无意义的条件：因负数没有算术平方根，所以当a﹤0时，没有意义。 知识点三：二次根式（）的非负性 （）表示a的算术平方根，也就是说，（）是一个非负数，即0（）。注：因为二次根式（）表示a的算术平方根，而正数的算术平方根是正数，0的算术平方根是0，所以非负数（）的算术平方根是非负数，即0（），这个性质也就是非负数的算术平方根的性质，和绝对值、偶次方类似。这个性质在解答题目时 应用较多，如若，则a=0,b=0；若，则a=0,b=0；若，则a=0,b=0。知识点四：二次根式（）的性质 （） 文字语言叙述为：一个非负数的算术平方根的平方等于这个非负数。 注：二次根式的性质公式（）是逆用平方根的定义得出的结论。上面的公式 也可以反过来应用：若，则，如：，. 知识点五：二次根式的性质 文字语言叙述为：一个数的平方的算术平方根等于这个数的绝对值。 注： 1、化简时，一定要弄明白被开方数的底数a是正数还是负数，若是正数或0，则等于a本身，即；若a是负数，则等于a的相反数-a,即； 2、中的a的取值范围可以是任意实数，即不论a取何值，一定有意义； 3、化简时，先将它化成，再根据绝对值的意义来进行化简。 知识点六：与的异同点 1、不同点：与表示的意义是不同的，表示一个正数a的算术平方根的平方，而表示一个实数a的平方的算术平方根；在中，而中a可以是正实数，

八年级数学 第十六章 二次根式 第一节 二次根式的概念和性质 二次根式 1． 二次根式的概念: 式子)0(≥a a 叫做二次根式．注意被开方数 只能是正数或O ． 2． 二次根式的性质 ①? ??≤-≥==)0()0(2a a a a a a ； ②)0()(2≥=a a a ③)0,0(≥≥?=b a b a ab ； ④)0,0(>≥=b a b a b a 最简二次根式与同类二次根式 1. 被开方数所含因数是整数，因式是整式，不含能开得尽方的因数或因式的二次根式，叫做最简二次根式． 2.化成最简二次根式后，被开方数相同的二次根式，叫做同类二次根式 二次根式的运算 1.二次根式的加减:先把各个二次根式化成最简二次根式，再把同类三次根式分别合并． 2.二次根式的乘法:等于各个因式的被开方数的积的算术平方根， 即 ).0,0(≥≥=?b a ab b a
3.二次根式的和相乘，可参照多项式的乘法进行． 两个含有二次根式的代数式相乘，如果它们的积不含有二次根式，那么这两个三次根式互为有理化因式． 4.二次根式相除，通常先写成分式的形式，然后分子、分母都乘以分母的有理化因式，把分母的根号化去(或分子、分母约分)．把分母的根号化去，叫做分母有理化． 二次根式的运算法则： c c c≥0) ?b a b a ab = ≥ ).0 ,0 (≥ a a =a≥0,b>0） b b =( a≥0) ()n n a a
