T he holiday is coming. It’s important for us to know t hat we should give something to the family members and spend time with them this time.
If you don’t have enough money, one of the first things you must do is cut back your spending to match your money. Although you lose your job or make less money, you still spend money as much as before. This is an easy way to get into trouble quickly.
I realize it is difficult to save money, especially in holidays. And it is not easy to let others know you are having difficulties. But it is something you must consider or you will have worse problems.
Some of our most important gifts were the simplest. My mother came from a family of ten children. When my grandmother got older and there were quite a few of us grandchildren, she still felt she should get each of us something. First, she would make each of us some cakes. Then in the later years, we each got a pair of socks. Now we still talk about getting socks from Grandma.
If you can’t buy the latest toys the kids wa nt, look for ways to send them special presents.

A marathon is 42 kilometers long. It is the longest race in the world. To make the runner’s body work, harder training is quite necessary. A runner should start to prepare for a marathon at least three months before. Preparation may have races, many hours of running at different speeds and changes in diet.

Two weeks before the marathon, the training program becomes less, from 100 kilometers per week down to 60 kilometers and then to 30 kilometers in the final week. On the last two days they may not run at all.
Runners should eat breakfast at least three hours before the race. Easily digested food such as cereal, toast and scrambled eggs is best, with as much fluid as possible. Runners should drink water about half an hour before the race.

学而思寒假七年级尖子班讲义第1讲平行线四大模型(1)教学文稿
目录 Contents 第1讲平行线四大模型 (1) 第2讲实数三大概念 (17) 第3讲平面直角坐标系 (33) 第4讲坐标系与面积初步 (51) 第5讲二元—次方程组进阶 (67) 第6讲含参不等式（组） (79)
1平行线四大模型 知识目标 目标一熟练掌握平行线四大模型的证明 目标二熟练掌握平行线四大模型的应用 目标三掌握辅助线的构造方法，熟悉平行线四大模型的构造 秋季回顾平行线的判定与性质 l、平行线的判定 根据平行线的定义，如果平面内的两条直线不相交，就可以判断这两条直线平行，但是，由于直线无限延伸，检验它们是否相交有困难，所以难以直接根据定义来判断两条直线是否平行，这就需要更简单易行的判定方法来判定两直线平行． 判定方法l： 两条直线被第三条直线所截，如果同位角相等，那么这两条直线平行． 简称：同位角相等，两直线平行． 判定方法2： 两条直线被第三条直线所截，如果内错角相等，那么这两条直线平行． 简称：内错角相等，两直线平行， 判定方法3： 两条直线被第三条直线所截，如果同旁内角互补，那么这两条直线平行． 简称：同旁内角互补，两直线平行， 如上图： 若已知∠1=∠2，则AB∥CD（同位角相等，两直线平行）； 若已知∠1=∠3，则AB∥CD（内错角相等，两直线平行）； 若已知∠1+ ∠4= 180°，则AB∥CD（同旁内角互补，两直线平行）． 另有平行公理推论也能证明两直线平行： 平行公理推论：如果两条直线都与第三条直线平行，那么这两条直线也互相平行． 2、平行线的性质 利用同位角相等，或者内错角相等，或者同旁内角互补，可以判定两条直线平行．反过来，如果已知两条直线平行，当它们被第三条直线所截，得到的同位角、内错角、同 旁内角也有相应的数量关系，这就是平行线的性质． 性质1：

(完整版)七年级尖子班讲义第1讲平行线四大模型
平行线四大模型 平行线的判定与性质 l、平行线的判定 根据平行线的定义，如果平面内的两条直线不相交，就可以判断这两条直线平行，但是，由于直线无限延伸，检验它们是否相交有困难，所以难以直接根据定义来判断两条直线是否平行，这就需要更简单易行的判定方法来判定两直线平行． 判定方法l： 两条直线被第三条直线所截，如果同位角相等，那么这两条直线平行． 简称：同位角相等，两直线平行． 判定方法2： 两条直线被第三条直线所截，如果内错角相等，那么这两条直线平行． 简称：内错角相等，两直线平行， 判定方法3： 两条直线被第三条直线所截，如果同旁内角互补，那么这两条直线平行． 简称：同旁内角互补，两直线平行， 如上图： 若已知∠1=∠2，则AB∥CD（同位角相等，两直线平行）； 若已知∠1=∠3，则AB∥CD（内错角相等，两直线平行）； 若已知∠1+ ∠4= 180°，则AB∥CD（同旁内角互补，两直线平行）． 另有平行公理推论也能证明两直线平行： 平行公理推论：如果两条直线都与第三条直线平行，那么这两条直线也互相平行． 2、平行线的性质 利用同位角相等，或者内错角相等，或者同旁内角互补，可以判定两条直线平行．反过来，如果已知两条直线平行，当它们被第三条直线所截，得到的同位角、内错角、同 旁内角也有相应的数量关系，这就是平行线的性质． 性质1： 两条平行线被第三条直线所截，同位角相等． 简称：两直线平行，同位角相等 性质2： 两条平行线被第三条直线所截，内错角相等. 简称：两直线平行，内错角相等 性质3： 两条平行线被第三条直线所截，同旁内角互补． 简称：两直线平行，同旁内角互补

初一春季班第八讲(1)
第八讲：Module 9 阅读完形训练 A Will it matter if you don?t have your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfast, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had eaten different kinds of breakfast. The results show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit, eggs, bread and milk before going to school, he will learn more quickly and listen more carefully in class. The result is opposite to what some people think. Having no breakfast will not help you lose weight. This is because people become so hungry at noon that they eat too much for lunch. They will get weight instead of losing it. You will lose more weight if you reduce your other meals. 1.During the test, the people were given ________. A.no breakfast at all C. different foods or sometimes none B.very rich breakfast D. little food for breakfast 2.The results show that ________. A.breakfast has a great effect (影响) on work and studies B.breakfast has little to do with a person?s work C. a person will work better if he only has fruit and milk D.girl students should have little for breakfast to keep fit 3.From the passage, some people think that if you don?t have breakfast, you will ________. A.be healthier B. work better C. lose weight D. lose your way 4.The underlined word “reduce” in the last sentence means ________ in Chinese. A.增加 B. 减少 C. 放弃 D. 享用 5.Which of the following is NOT true? A.It is bad for your health to have no breakfast. B.Too little for breakfast and too much for lunch may make you fatter. C.If you don?t eat much for lunch and supper, you may lose weight. D.The more breakfast you have, the more quickly you?ll learn in class. B How many school rules do you have? Le t?s know about what the teens think of? Mary: We have to eat lunch at school and are not ___1___ to bring our own meals. We can?t buy food outside of school either. And the canteen (食堂) food isn?t delicious. ___2___ sometimes I don?t eat it. But then I feel ___3___ in the afternoon. Because of this, I often eat a lot at supper. Now many of us have ___4___. Sally: I don?t like having so many classes each day and each week. A lot of stu dents feel sleepy and ___5___ after school. I suggest that schools should give us more ___6___ to do things we like.

平行线的判定与性质 模块一 知识点睛 如图所示，直线a 与直线b 只有一个公共点，称直线a 与直线b 相交，O 为交点，其中一条是另一条的相交线. 相交线的性质：两直线相交只有一个交点. 交点个数结论：同一平面内的n 条直线两两相交，其中无三线共点，则可得 )1(21-n n 个交点. 典型例题 【例1】判断正误： （1）两条直线相交不可能有两个交点（ ） （2）三条直线两两相交有三个交点（ ） （3）在同一平面内的三条直线的交点个数可能为0，1，2，3.（ ） （4）同一平面内的n 条直线两两相交，其中无三线共点，则可得)1(2 1-n n 个交点（ ） 模块二 知识点睛 1、邻补角 如图中，∠1和∠3，∠1和∠4，∠2和∠3，∠2和∠4互为邻补角. 互为邻补角的两个角一定互补，但两个角互补不一定是互为邻补角。 2、对顶角 （1）一个角的两边分别是另一个角的两边的反向延长线，这两个角叫做对顶角。我们也可以说，两条直线相交成四个角，其中有公共顶点而没有公共边的两个角叫做对顶角，如图中，∠1和∠2，∠3和∠4是对顶角。 （2）对顶角的性质：对顶角相等。
典型例题 （2）【例2】（1）下列四个命题： （3）①如果两个角是对顶角，则这两个角相等． （4）②如果两个角相等，则这两个角是对顶角． （5）③如果两个角不是对顶角，则这两个角不相等． （6）④如果两个角不相等，则这两个角不是对顶角． （7）其中正确的命题有（） （8）A．1个B．2个C．3个D．4个 （9）下列说法中正确的有（） ①一个角的邻补角只有一个； ②一个角的补角必大于这个角； ③若两个互补，则这两个角一定是一个锐角、一个钝角； ④互余的两个角一定都是锐角。 A.0个 B.1个 C.2个 D.3个 【例3】下列四个图中，∠ 与∠β成邻补角的是（） 【例4】如图所示，直线a、b、c两两相交，∠1=2∠3，∠2=65°，求∠4的度数。 能力提升 【例5】（1）如图所示，直线AB，CD相较于点O，若∠1-∠2=70°，则∠BCD= ，∠2= . （2） （3）如图，直线AB，CD相较于点O，若∠1：∠2=1：4，则∠1= ，∠3=

While he was doing his homework, the telephone rang. As he walked along the lake, he sang happily. He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory. (2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如： I’ll ring you up as soon as I get to New York. I will tell him everything when he comes back. He won’t believe it until he sees it with his own eyes. (3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直 到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”, “在…… 以前不……”, 谓语动词可用瞬间动词。例如： The young man read till the light went out. Let’s wait until the rain stops. We won’t start until Bob comes. Don’t get off until the bus stops. 2. 条件状语从句 (1)条件状语从句通常由if, unless引导。例如： What shall we do if it snows tomorrow Don’t leave the building unless I tell you to. (2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如： I’ll help you with your English if am free tomorrow. He won’t be late unless he is ill. (3)“祈使句 + and (or)+ 陈述句”在意思上相当于一个带有条件状语从句的复合句。例如： Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如： He didn’t come to school because he was ill.
