语法小结:

一、一般将来时

1.用be doing表示将来:主要意义是表示按计划、安排即将发生的动作,常用于位置转移的动词。

如:go,come,leave,arrive等,也可用于其他动作动词。

We are having fish for dinner.

We are moving to a different hotel the day after tomorrow.

这种用法通常带有表示将来的时间状语,如果不带时间状语,则根据上下文可表示最近即将发生的动作。

A: Where are you going? B: I am going for a walk. Are you coming with me?

A: Yes,I am just coming. Wait for me.

2.用be going to do表示将来:主要意义,一是表示―意图‖,即打算在最近的将来或将来进行某事。

Are you going to post that letter?

How long is he going to stay here?

I am going to book a ticket.

另一意义是表示―预见‖,即现在已有迹象表明将要发生或即将发生某种情况。

It’s going to rain.

George is putting on weight; he is going to be quite fat.

3. 用will/ shall do表示将来:

主要意义,一是表示预见。

You will feel better after taking this medicine.

Do you think it will rain?

二是表示意图.

I will not lend the book to you.

Take it easy,I will not do it any longer.

基本结构:

1. there be结构中的be是可以运用各种时态的。

There is going to be a meeting tonight.今晚有个会议。

There was a knock at the door.有人敲门。

There has been a girl waiting for you.有个女孩一直在等你。

There will be rain soon.不久天就要下雨了。

2. 动词be单复数形式要跟there be之后的真正的主语一致。并且要根据就近一致原则来

变换be的单复数形式。

如There is a book on the desk. 课桌上有一本书。

How many people are there in the city?这个城市里有多少人口?

There is a pen and two books on the desk.课桌上有一个钢笔和两本书。

There are two books and a pen on the desk.课桌上有两本书和一个钢笔。

There are some students and a teacher in the classroom.教室里有一些学生和一位老师。

There is a teacher and some students in the classroom.教室里有一位老师和一些学生。

3. 在there be引起的句子结构中,用来修饰主语的不定式主动形式和被动形式均可。

(3)如果直角三角形的两直角边长分别为a,b,斜边长为c,那么 a2+b2=c2。 (4)、直角三角形斜边上的中线等于斜边的一半 5、摄影定理:在直角三角形中,斜边上的高线就是两直角边在斜边上的摄影的比例中项,每条直角边就是它们在斜边上的摄影与斜边的 比例中项。① ②③ 6、常用关系式 由三角形面积公式可得:AB CD=ACBC 第十八章平行四边形 1、平行四边形定义:有两组对边分别平行的四边形叫做平行四边形。 2、平行四边形的性质:⑴平行四边形的对边相等;⑵平行四边形的对角相等:⑶平行四边形的对角线互相平分。 3平行四边形的判定:⑴、两组对边分别相等的四边形就是平行四边形; ⑵对角线互相平分的四边形就是平行四边形;⑶两组对角分别相等的四边形就是平行四边形; ⑷一组对边平行且相等的四边形就是平 行四边形。 4、矩形的定义:有一个角就是直角的平行四边形。 5、矩形的性质:⑴矩形的四个角都就是直角; ⑵矩形的对角线相等。 6、矩形判定定理:⑴有三个角就是直角的四边形就是矩形; ⑵对角线相等的平行四边形就是矩形。 7、中位线定理:三角形的中位线平行于三角形的第三边,且等于第三边的一半。 直角三角形斜边上的中线等于斜边的一半。 (连接三角形两边中点的线段叫做三角形的中位线。) 8、菱形的定义 :有一组邻边相等的平行四边形。 9、菱形的性质:⑴菱形的四条边都相等; ⑵菱形的两条对角线互相垂直,并且每一条对角线平分一组对角。 S菱形=1/2×ab(a、b为两条对角线长) 10、菱形的判定定理:⑴四条边相等的四边形就是菱形。 ⑵对角线互相垂直的平行四边形就是菱形。

(2)二次根式的乘除法:二次根式相乘(除),将被开方数相乘(除), 所得的积(商)仍作积(商)的被开方数并将运算结果化为最简二次根式. a ≥0, b ≥0);=b ≥0,a>0). (3)有理数的加法交换律、结合律,乘法交换律及结合律,?乘法对加法 的分配律以及多项式的乘法公式,都适用于二次根式的运算. a (a >0) a -(a <0) 0 (a =0);

第十七章 勾股定理 1.勾股定理:如果直角三角形的两直角边长分别为a ,b ,斜边长为c ,那么 c b a 222=+。 应用: (1)已知直角三角形的两边求第三边(在ABC ?中,90C ∠=?,则c , b ,a ) (2)已知直角三角形的一边与另两边的关系,求直角三角形的另两边。 2.勾股定理逆定理:如果三角形三边长a ,b,c 满足c b a 222=+,那么这个三角 形是直角三角形。 应用: 勾股定理的逆定理是判定一个三角形是否是直角三角形的一种重 要方法。 (定理中a ,b ,c 及222a b c +=只是一种表现形式,不可认为是唯一的,如 若三角形三边长a ,b ,c 满足222a c b +=,那么以a ,b ,c 为三边的三角形是 直角三角形,但是b 为斜边) 3、勾股数 ①能够构成直角三角形的三边长的三个正整数称为勾股数,即222a b c +=中, a , b , c 为正整数时,称a ,b ,c 为一组勾股数 ②记住常见的勾股数可以提高解题速度,如: 3,4,5; 6,8,10; 5,12,13; 7,24,25等 4.直角三角形的性质 (1)直角三角形的两个锐角互余。可表示如下:∠C=90°?∠A+∠B=90° (2)在直角三角形中,30°角所对的直角边等于斜边的一半。
