It’s every teenager’s nightmare (恶魔): exam time. During the last three days of the term, we have six exams.
My easiest exam was maths. All of its questions were from earlier exams.
The biology exam was hard. At first, I thought I had failed it. It asked lots of things we never studied in class, so we could use our textbooks. But there wasn’t enough time to check every question. I guessed on many of them. But my teacher said I did well.
On the career planning and computer applications (申请) exam, we had a lot to do: a PowerPoint presentation (显示), a book report and a class evaluation. I felt like I needed more time, but some of my classmates didn’t think so much. They just quickly wrote down some answers and then played games.
I don’t think I did very well in the English exam. We had to write an essay (读后感) about books we’ve read in class. But I didn’t study enough.
At our school, we can “Test out” of some classes. That means students can study by themselves and then take a class exam. If they pass, they don’t have to take the class, I tested out of both computer and health classes.w W w.xK b 1 . c om
Studying for those exams was terrible. Those classes go for six months, but I had to teach myself everything in three weeks. Also, I had to do three big projects at the same time. I watched no TV for almost three weeks! I am so glad it’s all over, and now it’s the summer holiday.
For my classmates, it will be two and a half months of fun without school or homework. But I’m a Chinese, and you know what Chinese parents do with their kids’ free time: still more homework.

It is _____________________.

83. For the writer’s classmates, how long will it be of fun without school or homework?
It will be _______________________________.

Everyone worries. But how do you deal with your worries? Whether (无论)your worries are big or small, you can take these three steps to deal with(处理) your worries:
1. Try to find out what you’re worried about
Sometimes, you will know what you’re worried about. Other times, you might not. Try to find it out first; if you can’t, you can ask for help.
2. Think of ways to make it better
There is always something you can do to help you feel less worried. Sitting there worrying is no fun and it won’t solve(解决) your problem.
Grades at school are often a top worry for kids. If you’re worried about grades, ask yourself these questions:
☆ Why are grades important? What do grades mean to me?
☆ How do I get ready for class? Do I go over my notes even when there isn’t a test?
☆ Do I have a good place to do my homework?
☆ Have I tried different ways of studying?
If your worry is about a fight you had with a friend, you might write down all the things you could do-write a note to him or her, invite(邀请)him or her to a basketball game, say sorry to him or her etc. Once you have a list of things you could do, you can choose the one that gets your friend back.
3. Ask for help
When you’re worried, it can help to find someone to talk to. You can ask your parents, friends, or teachers for help.

Jane Goodall was born in London. When she was one year old, her mother took her to the zoo to see chimps(猩猩). Jane began to love the chimps.
When she was seven years old, she read a book about a doctor who could talk to animals. Then she wanted to be able to talk to animals, too. Her favorite animal was chimps.
When she was twenty-six years old, she went to Africa with all her money. She began to study chimps there instead of going to university. In Gombe National Park of Africa, she watched them carefully day after day.
At first, the chimps were afraid of her, so she had to watch them far away. After three or four months, the animals accepted(接受) her. And then, she went to live in the forests. At last they became her friends. She found the chimps acted so much like people. They could think and make plans. They used tools. They could show their feelings when they were happy, sad or mad. She learned their language.
Jane Goodall studied chimps for more than forty years. She is a very famous scientist in the world.

为纪念中国人民抗日战争64周年，灵宝市一所中学八年级某班黑板报准备出一期专刊。该班一位同学提供了一篇概述日本侵华主要史实的稿件，其中有五处与史实不符。请你找出并加以更正。
1929年，为摆脱危机，日本发动了侵略中国的“九一八”事变，不到半年，它就将富饶美丽的东北三省置于其铁蹄之下。1937年，在上海制造“七七事变”，发动全面侵华战争。接着，日本发动了“一二八事变”，大举进攻上海。同年12月，日军攻陷南京，对南京和平居民进行惨绝人寰的大屠杀，我国同胞20万被野蛮的日军杀害。1945年8月15日，主要因为美军先后在日本广岛和长崎投掷原子弹，侵略中国的日本帝国主义被迫宣布无条件投降。

20.略
21.解：(1)△ABE≌△CDF，△AFD≌△CEB.
(2)选△ABE≌△CDF进行证明.∵AB∥CD，∴∠1=∠2.
∵AF=CE，∴AF+EF=CE+EF,即AE=FC，
在△ABE和△CDF中，∴△ABE≌△CDF(AAS).
22.(1)证明：如图，∵AD⊥CE，∠ACB=90°，
∴∠ADC=∠ACB=90°，∴∠BCE=∠CAD(同角的余角相等).
在△ADC与△CEB中，
，∴△ADC≌△CEB(AAS);
(2)由(1)知，△ADC≌△CEB，则AD=CE=5cm，CD=BE.
如图，∵CD=CE﹣DE，∴BE=AD﹣DE=5﹣3=2(cm)，即BE的长度是2cm.
23.(1)33?(2)26cm或23cm
24.解(1)：小丽的说法正确，理由如下：
原式=4x2-y2-(8x2-6xy+y2)+2y2-6xy
=4x2-y2-8x2+6xy-y2+2y2-6xy=-4x2.
化简后y消掉了，所以代数式的值与y无关.所以小丽的说法正确.
(2)-16
25.(1)AM平分∠DAB.
证明：过点M作ME⊥AD，垂足为E.
∵∠1=∠2,MC⊥CD,ME⊥AD，∴ME=MC[(角平分线上的点到角两边的距离相等).
又∵MC=MB,∴ME=MB.∵MB⊥AB,ME⊥AD
∴AM平分∠DAB(到角的两边距离相等的点在这个角的平分线上).
(2)AM⊥DM，理由如下：
∵∠B=∠C=90°∴CD∥AB(垂直于同一条直线的两条直线平行).
∴∠CDA+∠DAB=180°(两直线平行，同旁内角互补)
又∵∠1=∠CDA,∠3=∠DAB,(角平分线定义)
∴2∠1+2∠3=180°，∴∠1+∠3=90°
∴∠AMD=90°即AM⊥DM.
26.(1)30
(2)(1)中结论成立.
证明：∵正△ABC、正△CDE∴AC=BC，EC=DC，∠ACB=∠DCE=60°，
∴∠ACD=∠BCE∴△ACD≌△BCE∴∠CAD=∠CBE.又∵正△ABC中，M是BC中点.
∴∠CAD=∠BAC=30°.∴∠CBE=30°
(3)CE=3
