B1U1 Friendship 固学案2

一.阅读理解

A

L ife affects friendships. As we grow, marry, fight in wars, move across the country or change jobs, old friendships fall away and new ones form. As long as we live, the things around us change, and as long as things change, friendships are affected.

When we were children we had best friends. No matter what happened we were still friends. We live our lives, however, and do what life calls for us to do, and as we get older, memories fade, faces blur, and even friends' names from childhood are forgotten.

Do you have a question about friendship? Do you wonder what to do with a friend who is no longer friendly? Perhaps you will see that you can't control others. If someone wants to be your friend, it is their choice. All you can do is treat them well and do the best for them when you are with them. Then you wish them well when they leave.

You can talk to old timers and they will tell you that life is full of incredible joy and incredible sorrow, and that what bothers you today will one day becomes a memory and the sting(痛苦) will be gone. Seniors might tell you that you will learn more as you get older. They will tell you that friendships come and friendships go. Sometimes when they go it will hurt, but you will be okay with it. It's the way life works, after all.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

What do you do to take care of the books in your library？Some collectors refuse to read the books in their collections, so the books remain in good condition. Others buy two copies of a book：They read one, and leave the other untouched. __11__ Here are some tips to remember if you want your books to remain in good condition.

?Avoid writing.

You may have been told to write in your books, or even to underline words, phrases, and paragraphs. But if you plan to keep the book, add it to your library, or even sell it, don't write in the book. __12_ Use a notebook to take notes or use pieces of paper. If you are required to write in your book, use a pencil, and remove the markings later.

?Avoid food and drinks.

Food and drinks are things that may be dangerous to your books, so the best way is to avoid eating or drinking while you read. If you need to read while you eat, make sure your fingers are clean and dry as you hold the book or turn the pages. __13__

?Take care.

__14__ Don't let it drop to the ground. When you read the book, don't fold(折) the corners of the pages (use a bookmark instead). Don't place your book with the book open, face down. You'd better use a book cover to keep your book in the best condition.

?__15__

If you want to take care of your books, keep your books on a shelf when you are not reading them. But, also, take care that the books should be placed in an upright(竖直的) position.

A．Put it on the shelf.

B．Protect it from dust.

C．The ink may damage your book forever.

D．When you handle your book, hold it with care.

E．No one knows exactly how to protect their books.

F．Also, keep the book well away from food and drinks.

G．However, many readers must read their books, but they still want to protect them.

2021-2022版高中物理人教版选修3-2学案：第四章 6 互感和自感

6 互感和自感 目 标导航思维脉图 1.知道互感现象和自感现象都属 于电磁感应现象。(物理观念) 2.知道自感电动势对电流变化的 影响符合楞次定律。(物理观念) 3.知道自感电动势大小受到哪些 因素影响。(科学探究) 4.了解自感现象在生产生活中的 应用和怎样预防其带来的不利影 响。 (科学思维) 必备知识·自主学习 一、互感现象 二、自感现象 1.自感现象:一个线圈中的电流变化时,它所产生的变化的磁场在它本

身激发出感应电动势的现象,产生的电动势叫作自感电动势。 2.通电自感和断电自感: 电路现象 自感电动势 的作用 通电 自感接通电源的瞬间,灯泡A1较慢地亮起来 阻碍电流 的增加 断电自感 断开开关的瞬间,灯泡A逐渐变暗。有时灯泡 A会闪亮一下,然后逐渐变暗 阻碍电流 的减小 3.自感系数: (1)自感电动势的大小:E=L,其中L是线圈的自感系数,简称自感或电感。 (2)单位:亨利,符号:H。常用的还有毫亨(mH)和微亨(μH)。换算关系是:1H=103mH=106μH。 (3)决定线圈自感系数大小的因素:线圈的大小、形状、圈数以及是否 有铁芯等。 三、自感现象中的能量转化 1.自感现象中的磁场能量: (1)线圈中电流从无到有时,磁场从无到有,电源的能量输送给磁场,储 存在磁场中。 (2)线圈中电流减小时,磁场中的能量释放出来转化为电能。 2. 电的“惯性”:

自感电动势有阻碍线圈中电流变化的“惯性”。 (1)自感现象中,感应电动势一定和原电流方向相反。(×) (2)线圈中产生的自感电动势较大时,其自感系数一定较大。(×) (3)对于同一线圈,当电流变化较快时,线圈中的自感电动势也较大。(√) (4)没有发生自感现象时,即使有磁场也不会储存能量。(×) 关键能力·合作学习 知识点一自感现象的产生与规律 1.自感现象的产生:当线圈中的电流变化时,产生的磁场及穿过自身的 磁通量随之变化,依据楞次定律,会在自身产生感应电动势,叫自感电 动势。 2.规律:自感现象也是电磁感应现象,也符合楞次定律,可表述为自感 电动势总要阻碍引起自感的原电流的变化。 (1)当原电流增加时,自感电动势阻碍原电流的增加,方向与原电流方 向相反。 (2)当原电流减小时,自感电动势阻碍原电流的减小,方向与原电流方 向相同。 (3)自感电动势总要阻碍引起自感的原电流的变化,但阻止不住,只是 变化得慢了。 收音机里的“磁性天线”怎样把广播电台的信号从一个线圈传到另一 个线圈?
