Every spring, there are sports meets at many middle schools. When students on the playground get together and shout loudly, “One, two, one, two." Do you know what game it is It is tug-of-war.
Tug-of-war is a team sport between two teams at each end of a rope (绳). It first came into being in China 2,400 years ago. It is very popular in China and many other countries. But in other countries, their tug-of-war match is a little different from ours. They have eight men for each team , while we may have the match between two sides with the equal number of men or women players. For example, we may have 10 men players and 10 women players on each team. Of course, they are usually tall, strong and heavy.
For a tug-of-war match , we need a long thick (厚的) rope. Each team stands at one end of the rope, holding it. There's a white line in the middle of the field. Then they try to pull (拉) the centre of the rope to each of their own sides. The winning team is the one that pulls the other over the line.
Tug-of-war was once an Olympic sporting event. It lasted until 1920. Though it isn't an Olympic sport now, people in many countries still like playing it very much.

(5) A 凹液面最低处 温度可控、受热均匀 70 加入溶质硝酸钾、蒸发水、降低温度 CD
【详解】（1）20℃时NaCl的溶解度为36g，其含义是20℃时，在100g水中溶解36gNaCl形成饱和溶液。
（2）影响固体溶解度大小的因素有溶质种类、溶剂种类、温度，压强几乎不影响固体溶解度，搅拌、颗粒大小、溶质、溶剂质量都不会影响溶解度；
故选AC。
（3）A. 温度升高，微粒运动加快，可以加快物质溶解，正确；
B. 搅拌可以加快物质溶解，正确；
C. 颗粒越小，与溶剂接触面积越大，溶解越快，正确；

15
√
答案
将两个含有氢原子的相邻碳原子之间的单键变成双键即可，
如 在①②③④处均可使碳碳单键变为碳碳双键
但①②处位置是等效的，所以该烯烃可能的结构简式有3种。
