Every year people celebrate the Spring Festival in China. It is usually in January or February. It’s the most important festival in China. So before it comes, everyone buys many things. And they often make a special kind of food called dumplings. It means(意思是) ‘come together’. Parents always buy new clothes for their children and children also buy presents for their parents.
On the Spring Festival Eve (除夕), all the family members come back home to have a big dinner. When they enjoy the meal, they give the best wishes to each other for the coming year. After dinner, all the family stay up until midnight to welcome the New Year. They sing, dance and play cards.
On the first day of the new year, people put on new clothes and visit their friends. They say ‘Happy New Year!’ to each other. They all have a good time during the festival.
1. When is the Spring Festival in China every year?

2. What do people do before the Spring Festival comes?

3. What do ‘dumplings’ mean?

4. What do children get from their parents ?

5. Do people have fun at the Spring Festival?

如图，∠1、∠2、∠3、∠4是五边形ABCD的外角，且∠1=∠2=∠3=∠4=70°，则∠AED的度数是。

当c= 2 时，关于x的方程2x²+8x+c=0有实数根．（填一个符合要求的数即可）

已知一组数据：7，2，x，8，1的极差为9，则x的值是-1或10 ．

在实数范围内定义一种运算“*”，其规则为a*b=a²-b²，根据这个规则，方程（x+2）*5=0的解为x=3或x=-7 ．

用锤子以均匀的力敲击铁钉入木板．随着铁钉的深入，铁钉所受的阻力会越来越大，使得每次钉入木板的钉子的长度后一次为前一次的k倍（0＜k＜1）．已知一个钉子受击3次后恰好全部进入木板，且第一次受击后进入木板部分的铁钉长度是钉长的

，设铁钉的长度为1，那么符合这一事实的一个方程
是。

如图所示，两块完全相同的含30°角的直角三角板叠放在一起，且∠DAB=30°．有以下四个结论：①AF丄BC；②△ADG≌△ACF；③O为BC的中点；④AG：DE=

：4，其中正确结论的序是①②③④ ．（错填得0分，少填酌情给分）．

课题研究小组对附着在物体表面的三个微生物（课题小组成员把他们分别标号为1，2，3）的生长情况进行观察记录．这三个微生物第一天各自一分为二，产生新的微生物（分别被标号为4，5，6，7，8，9），接下去每天都按照这样的规律变化，即每个微生物一分为二，形成新的微生物（课题组成员用如图所示的图形进行形象的记录）．那么标号为100的微生物会出现在第天。
