五、(2025·苏州阶段测)阅读理解。
Hold your hands together,and you will feel the heat(热量) from them. Did you know that this heat could be a kind of energy?
Ann Makosinski,a girl from Canada made a flashlight(手电筒) that only uses the heat from your hands as power. The invention won a top prize in Google Science Fair's 15~16 age group. Makosinski was just 15 then.
Makosinski has been interested in human energy since she was in Grade 6. She said as humans,we produce(产生) heat every minute. She wanted to make use of that to light up the flashlight.
She found a kind of tile(片状材料). These tiles produce electricity(电) when one side is heated and the other side is cooled.
She put the tiles both inside and outside of the flashlight. Holding it with your hands would make the tiles heat up on one side. At the same time,the air cools the tiles inside the flashlight.
The electricity that was made by the tiles was enough for an LED light,but it did not make so much voltage(电压). Without voltage,flashlights will not light up.
To work out the problem,Makosinski spent months finding information on the Internet and doing experiments(实验) at home. She said sometimes she thought it would never work,but she knew she just had to keep going.
In the end,she made it and she has got a patent(专利) for her flashlight.
1. Which of the following is TRUE about the flashlight?
A. It was invented by a girl from Britain.
B. It uses the heat from people's heads.
C. It came second in Google Science Fair.
D. It had tiles both inside and outside of it.
2. What does the underlined word "that" refer to?
A. A special type of tiles.
B. Electricity produced by tiles.
C. Heat produced by humans.
D. Google Science Fair.
3. Which of the following can best describe Makosinski?
A. Being clever and pretty.
B. Helping others warmly.
C. Working at school carefully.
D. Never giving up.
