承包人在双方确定设计变更后的14天内，未向工程师提出变更工程价款的报告，( )。A

Last Friday, after doing all the family shopping in town, I wanted to have a rest before catching the train. I bought a newspaper and some chocolate and went into the station coffee shop. It was a cheap self-service place with long tables to sit at. I put my heavy bag down on the floor, put the newspaper and chocolate on the table and then  (A) 去要一杯咖啡.

When I came back with the coffee, there was someone sitting in the next seat. It was a boy,  with dark glasses and old clothes, and his hair was coloured bright red at the front. He had started to eat my chocolate!

Naturally, I was rather uneasy about him, but I didn’t want to have any trouble. I just looked down at the front page of the newspaper, tasted my coffee and took a bit of chocolate. The boy looked at me closely. Then he took a second piece of my chocolate. I could hardly believe it. （B）Still I didn’t say anything to him. When he took a third piece, I felt more angry than uneasy. I thought, “Well, I shall have the last piece.” And I got (C) it.

The boy gave me a strange look, then stood up. As he left he shouted out, “There’s something wrong with that woman!” Everyone looked at me, but I did not want to quarrel with the boy, so I kept quiet. I did not realize that I had made mistake until I finished my coffee and was ready to leave. My face turned red when I saw my unopened chocolate (D) _______ the newspaper. The chocolate that I had been eating was the boy’s!

在同一地方，夏天大树树荫下的气温要比阳光直晒下的气温明显低，其主要原因是什么呢？几位同学有不同意见：小王认为主要是树叶不断散发出大量的水分，有降温的作用；小李认为主要是树叶挡住了太阳光的辐射，所以树荫下的气温降低了。

请回答下列问题：

（1）、小王认为主要是“树叶不断散发出大量的水分，有降温的作用”的科学原理是       

（2）、小方认为造成树荫下的气温要比阳光直晒下的气温低，除了小王和小李说的原因外，从能量转化的角度看，还有一个较重要原因，你认为这个原因是                 

(3)、小李针对自己的猜想，设计以下的实验来加以验证：

①在同一地点选择间隔适当距离，阳光照射、周边环境一样，树种、大小、长势、树形都相同的两棵树，分别编号为A,B。

②在B树全部树叶的正反两面喷上一层极薄无色无害不溶于水的透明膜，阻止树叶水分蒸发。（透明膜经过一段时间后，会自动分解）

③在无风晴天的中午实验地点进行测量，同时测定离地1.5米高处的三个点的气温。

这三个点的气温分别是：    下的气温(T₁）、   下的气温(T₂）、       下的气温(T₃)。

测温时，其中两支温度计放置地点除离地高度相同外，还应离               的距离相同。

④若不考虑小方说的造成树荫下气温低的原因，要证明小李的猜想是正确的，测量得到的数据 (T₁、T₂、T₃)之间的温差关系式应是
