40. What is the best title for the text
A. Read people like books B. Thoughts or feelings
C. Use body language well D. The art of communication
B
Lao Zi once said, “Care about what other people think and you will always be their prisoner.”
People-pleasing, or seeking self-worth through others’ approval, is unproductive and an exhausting way to go through life. Why do we allow what others think of us to have so much power over how we feel about ourselves If it’s true that you can’t please all people all of the time, wouldn’t it make sense to stop trying
Unfortunately, sense often isn’t driving our behavior. For social beings who desire love and belonging, wanting to be liked, and caring about the effect we have on others, is healthy and allows us to make connections. However, where we get into trouble is when our self- worth is dependent on whether we win someone’s approval or not.

Maybe it's not the nicest, but it is a must-visit stadium(体育馆)in Mexico. Lying in the suburbs of Santa Ursula in Mexico City, it is the stadium that hosts the national soccer game in Mexico. When the 1970 World Cup was there, it hosted 10 matches, including the semi-final, and the final between Brazil and Italy. Estadio Azteca is the largest stadium in Mexico, with a capacity (容量)of 87,523.
Olympic Stadium
Given that Canada doesn't have that many professional sports teams (at least not with the same popularity of US teams), stadiums north of the border are generally smaller and don't quite get the same investment(投资)that stadiums south of the border do. The stadium was used for the Montreal Expos, and now is carefully used for soccer games. In fact, it's set to host some World Cup games in 2026, but anybody who's been inside can tell you it's not a stadium fit to host such a big event.
Madison Square Garden
Madison Square Garden is one of the best stadiums in North America, and not just for sports, but for concerts and other events as well. If you are traveling into New York City by train, you will see the stadium right as you enter the city, above the train station. Before you get to your seats, the outskirts of the stadium actually look like a high-end hotel. It won't disappoint(使失望)you.
Michigan Stadium
Would you be surprised to know that the second largest stadium in the world is a college football stadium That's right. Michigan Stadium, home of the University of Michigan Wolverines, is the largest stadium in the United States and the second-largest stadium in the world. It has a capacity of 107,601.When you see Michigan Stadium, you know you're talking about college football.

【11题答案】

（5）镁与氧气反应放热，气体膨胀，装置内压强增大，因此气球的作用除了使装置密闭之外，还可以平衡压强，防止橡胶塞弹出。
28．(1) 银白色固体表面有紫红色固体析出，溶液由蓝色变为浅绿色 Fe+ 2AgNO3=2Ag +Fe(NO3)2
(2)没有比较铜和银的活动性顺序
(3) 把②中的铁丝换成铜丝 铁>铜>银
【详解】（1）铁的活动性在铜前，铁能和硝酸铜反应生成硝酸亚铁和铜，该反应的实验现象为银白色固体表面有紫红色固体析出，溶液由蓝色变为浅绿色。②中发生的反应为铁和硝酸银反应生成硝酸亚铁和银，该反应的化学方程式是Fe+ 2AgNO3=2Ag +Fe(NO3)2。
（2）实验①能证明铁的活动性强于铜，实验②能证明铁的活动性强于银，该实验的错误之处是没有比较铜和银的活动性顺序。
（3）反思后甲同学对自己的实验进行了改正，其做法是把②中的铁丝换成铜丝，观察到铜丝表面有银白色固体析出，溶液由无色变为蓝色，证明铜的活动性强于银，由此证明了三者的金属活动性顺序是铁＞铜＞银。
