答案

参考答案:A

解析:病儿肺部呼吸音低,腹部凹陷,而且心音在右侧,说明腹腔脏器疝入胸腔并引起纵隔移位的可能性极大。确诊需胸腹部X线摄片,可见充气的肠管及胃泡在胸腔内。

For an everyday and useful invention, I think it is the air- conditioner. I live in Hong kong.
During the summer, the temperature reaches 35 degrees or more. The heat is terrible. Without air
-conditioner, people here cannot work or study. A lot of people will also get sick without cool
air.

In my opinion, there is an invention that is important-electricity. Of course, this isn't a man
-made invention, but without electricity, many of the world's most important inventions would
not work.

I think the most important invention of all time is the mobile phone. It makes us easy to get
information from all over the world. Parents can use the mobile phone to get in touch with their
kids. And we can enjoy the music or films through the mobile phone.
