Teaching is one of the most rewarding(有回报的)jobs. It is also one of the most stressful. If you want to be a teacher, you should have a passion(激情)for young people. If you are thinking about going into teaching for any other reason than this, you need to find another job.

Teaching is difficult. Students can be difficult. Parents can be difficult. If you do not have a passion for the young people that you teach, you will burn out quickly. Passion is what keeps an excellent teacher going. When students have trouble understanding what is taught, it is what drives him to spend long hours trying to think out how to help them. If you do not have enough passion for your students, you might last a year or two, but not long. Passion is a must-have quality(品质)for every good teacher.

Teaching can be rewarding, but you shouldn’t expect that reward to come easily. Teachers who search out better and new methods are the ones who will make it. A good teacher needs to be able to work with everyone. All teachers face stress. It is important to be able to deal with everything that is thrown at you when you walk through your classroom doors. There are so many chances for stress within a classroom that an excellent teacher has to be able to bring it in control. If you cannot manage stress quite well, then teaching may not be the right job for you.

八年级数学下册知识点总结(全)

八年级数学下知识点总结 函数及其相关概念 1、变量与常量 在某一变化过程中,可以取不同数值的量叫做变量,数值保持不变的量叫做常量。 一般地,在某一变化过程中有两个变量x与y,如果对于x的每一个值,y都有唯一确定的值与它对应,那么就说x就是自变量,y就是x的函数。 2、函数解析式 用来表示函数关系的数学式子叫做函数解析式或函数关系式。 使函数有意义的自变量的取值的全体,叫做自变量的取值范围。 3、函数的三种表示法及其优缺点 (1)解析法 两个变量间的函数关系,有时可以用一个含有这两个变量及数字运算符号的等式表示,这种表示法叫做解析法。 (2)列表法 把自变量x的一系列值与函数y的对应值列成一个表来表示函数关系,这种表示法叫做列表法。 (3)图像法:用图像表示函数关系的方法叫做图像法。 4、由函数解析式画其图像的一般步骤 (1)列表:列表给出自变量与函数的一些对应值 (2)描点:以表中每对对应值为坐标,在坐标平面内描出相应的点 (3)连线:按照自变量由小到大的顺序,把所描各点用平滑的曲线连接起来。 正比例函数与一次函数 1、正比例函数与一次函数的概念 一般地,如果(k,b就是常数,k0),那么y叫做x的一次函数。特别地,当一次函数中的b为0时,(k为常数,k0)这时,y叫做x的正比例函数。 2、一次函数的图像 所有一次函数的图像都就是一条直线。 3、一次函数、正比例函数图像的主要特征: 一次函数的图像就是经过点(0,b)的直线;正比例函数的图像就是经过原点 (0,0)的直线。(如下图) 4、正比例函数的性质 一般地,正比例函数有下列性质: (1)当k>0时,图像经过第一、三象限,y随x的增大而增大; (2)当k<0时,图像经过第二、四象限,y随x的增大而减小。 5、一次函数的性质 一般地,一次函数有下列性质: (1)当k>0时,y随x的增大而增大 (2)当k<0时,y随x的增大而减小 6、正比例函数与一次函数解析式的确定

Unit 1 A 1.advice n. 建议,忠告,劝告 (1)advice是不可数名词,表示“一条建议”“两条建议”“一些建议”可用: a piece of advice;two piece of advice;some advice (2)advice作名词时的常用搭配: ①ask sb. for advice征询某人的建议 ②give sb. some advice= give some advice to sb.给某人提出一些建议 ③give advice on sth.在某方面给出建议 ④take (follow) one’s advice接受某人的建议 e.g. He often gives us some advice.=He often gives some advice to us. 他经常给我们一些建议。 ★例题:Your ______ is very helpful. I guess I’ll take it. A. secret B. advice C. promise D. purpose 答案:B 秘密;建议;承诺;目标。由下句“我想我会采纳。”可知“你的建议很有用”。 2.What’s the matter?怎么了? (1)该句用来询问对方所遇到的麻烦,或医生及护士询问病人身体情况,常与with 连用,后跟sb./sth.,意为“某人或某物怎么了?” e.g.——What’s the matter (with you)? (你)怎么了? ——I lost my pen./I have a cold. 我把我的钢笔弄丢了。/我感冒了。 (2)“(你)怎么了?”各种常见表达: What’s the matter (with you)? =What’s the trouble (with you)? =What’s the problem(with you)? =What’s wrong (with you)?=What’s up? =What happened? ★例题:——Nick is not at school. _______? ——He has a cold. A. Who’s that B. What’s the matter C. How old is he D. How much is it 答案:B 句意:——Nick没来上学。怎么回事? ——他感冒了。 ①此类句型中,matter,problem前需加定冠词the,trouble前可加the或形容词性物主代词;wrong是形容词,其前不加任何修饰词。 ②此类句型中,what即为句子主语,本身构成陈述语序,故当句子以宾语从句身份出现时,不可将be移至the matter/trouble/problem之后。 3.have a stomachache胃疼 (1)have +a(n)+名词,表示患某种病 e.g. have a cold感冒have a toothache牙疼
