预备初一数学的填空题（共有4题）

(1)行为人已经开始实施犯罪的预备行为.(2)行为人尚未着手犯罪的实行行为.(3)行为人的意图和目的,是为了顺利着手实施和完成犯罪.(4)犯罪在实行行为尚未着手时停止下来,是由于行为人意志以外的原因所致.

第一步算出1班收集了的电池数为40*25%=10千克
男生收集电池数位3/(3+7)=3/10
则男生收了10*3/10=3千克
那么女生收了10-3=7千克

ab:bc:ac=10:12:15
另ab=10x bc=12x ac=15X
则ab:bc=10:12 a:c=5:6
同理可得bc:ac=12:15 b:a=4:5
则连比可得a:b:c=5:4:6

方法就是把60因式分解
60=2*2*3*5
所以组成的长方形可以是
1*60
2*30
3*20
4*15
5*12
6*10
分别代表长方形的长和宽啊.理由嘛,就是因式分解,然后把把因式和因式的积按从小到大排列,就得到了!

乐易突破英语音标是一本适合小学生学习的启蒙音标教材,适用于二三年级起使用,由于讲解的是音标最基本的规律,所以可适用于没有系统学过音标的学生.这本音标教材着重从三方面入手解决学生的音标学习问题：
第一方面,整体认读48个音标.教材遵循“整体学习和部分学习”的教学规律,先是让孩子一节课把48个音标记忆下来,然后教给学生音标拼读规则.在学习过程中,主要运用了TPR教学法,
自然拟声法,谐音记忆、顺口溜等方法,对音标进行分解记忆,使用学生在短时间内能突破音标.
第三方面,对48个音标,分部分学习.在每一课中,重点学习拼读组合和音形对接.对于低年龄阶段学生,单词量比较少,逻辑归纳能力欠缺,建议多学习拼读组合,并且要多加练习.对高年龄阶段的学生,认识能力较强,不仅要学拼读规则,更要注意音形对接,扩大学生的单词量,真正实现孩子的“听音能写”.

证明：
∵BE⊥AC,CD⊥AB
∴∠ADC=∠AEB
∵∠A=∠A
∴△ABE∽△ACD
∴AE/AD=AB/AC
∴AE/AB=AD/AC
∵∠A=∠A
∴△ADE∽△ACB（两边成比例,夹角相等）

在我的眼里,春天永远最美丽!

你好,同学：

1. Our Class
We are in Class 1, Grade 1. There are 40 students in our class. Twenty-two boys and eighteen girls. Our classmates are very active and like doing sports. After class we often play basketball or play football. We are very happy. We all work at our lessons. We listen to the teacher carefully. And our teacher Miss Zhang often praises us. And we all like her. She loves us, too.
This is our class. I like my class and classmates very much.
2. How to get on with friends
Everyone has a friend. A friend is a person who will help you when you are in difficulty. But sometimes we have something unhappy between we and friends. Maybe we can quarrel with each other because of something. What should we do if we quarrel with our friends? Let me tell you.
Being a friend, you must understand your friend. If he has something different from you. You should respect your friend's idea and try your best deal with the things. But if you really can't get the same idea, even quarrel about it. I think you should applogize him or her when you get calm. Say "sorry" to him or her, and he or she will forgive you. You can get on well each other later.

3. My First Day of New Year
At the first day of New Year, I was so excited that I got up very early in the morning. But Mother was earlier than me, and she had gotten the breakfast ready. Dumplings, that's my favourite. After the wonderful breakfast, I left home with my parents to visit our relatives. On the way, I said "Happy New Year" to everyone that I met and they all said that back to me. Everyone is happy and friendly. In my relatives' house, they prepared many sweets and snacks for visitors. They are all very delicious. The more exciting thing was that I got some money from my relatives. I had a fine day in my relatives' family.
My first day of New Year was very happy. It was a good start, and I would try my best to make this happiness last for the whole year.

4. I have a dream
Everyone has his dreams,some of them dream of becoming a teacher,others a doctor,or a policeman.but I have a another kind of dream. My dream is a nice dream,in my dream, I am an angel, I have a pair of wings,so i can fly! I can fly high in the sky.in the sky, I can see beautiful clouds, I can see people and houses down on the earth moving up and down, I can see the great wall and other places of interests. I am a angel, so I can make many things come true with my power. I can help poor children come to school and I can make the blind able to see the world! I am an angel so I don't have to do my homework and I don't have to play the piano.

5. Respect old people
I always show my respect and love to the old. My grandparents don’t live with us, but we always do our best to help them. I have also visited their home to accompany the old and chat with them.
In my opinion, it is our duty to take care of the old. The old have been worked hard all their lives. And they gave lives to us and brought us up. I think the old should be paid more attention to though their children may be busy working and ignore them.
The old not only need money and presents, they also need respect and love.

90的约数2,3,5,6,9 ,10,15,30,45 ====
66的2,3,6,22,33====
可以看出他们最大公约数是6..
而90/6+1=16 ==【加1是因为有n个空挡那么就会有n+1 棵树】
66/6+1=12
所以,最远应每隔6米种一棵.
16*2+12*2=56
56-4=52====[减去四角重复计算的4棵]
所以,一共需要树苗52棵.

你自己写,这样才能上好学

Draw free body diagram,and then write balance in vertical direction:
mg - N = ma,where N is the normal force = the new scale reading
Plug in a = 0.15 g,and solve for N,
N = 0.85 mg
So,the ratio is N/(mg) = 0.85mg/(mg) = 0.85
