阅读理解

    Have you ever really looked at a tree? All trees are big plants. Like all plants, trees have roots. The roots hold trees in the ground. They keep trees from falling over. They bring water and food that trees need to live on.

    A tree has a fat stem. We call the tree's fat stem "trunk". Inside the trunk, a tree holds water and food. The water and food go up through the trunk to the green leaves. The leaves use sunlight to make more food for the tree.

    Trees help us. They help clean the air. They give us food. Fruits, nuts and chocolate all come from trees. Paper, chairs, beds and houses also come from trees. Trees are also important for other living creatures (生物). They provide a home for birds and other animals. Many animals eat part of trees. Be friends with trees! We need trees and trees need us! Often young trees need special care. They need water and protection (保护).

There were many famous inventors and scientists in history. You must have heard about a lot of them and known them well. But you may not know Nikola Tesla. 

Nikola Tesla and his inventions were well- known to people in the area of science and electricity, but not quite known to the general public today. Nikola Tesla was a Serbian- born inventor, who later moved to the US. He was most well- known for his inventions in the area of electricity and electrical engineering. He was considered one of the greatest electrical engineers in history. 

Why was Nikola Tesla not well- known while others in his time became so famous to the public? Some said Nikola Tesla failed to make the right business decisions. Others said it was because of his "mad scientist" qualities (特质) — the same qualities that helped him come up with some of his best ideas. His qualities led him to many strange ideas. Towards his last years, he came up with many ideas that seemed unacceptable to the public at that time. He worked very hard on them, which made people think he was mad. 

Many of Tesla's inventions and patents (专利) didn't end up being used in the exact way he had planned for them. Some of those include his high- frequency lighting ideas, wireless power and the free energy receiver. 

If you are interested in green energy and reducing your electricity bill, check out products that are developed from Tesla's work. They help create green energy at home, without depending on the electricity companies and without paying for it. They help people save money through producing electricity at home, based on Nikola Tesla's inventions. 

Tesla had too many inventions. However, he never really made a lot of money out of them. He had a bigger dream: to provide free energy for all. 

Nikola Tesla is not alone. There are many other inventors who invented many useful things but are not known to the public. 

 阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。

Are there any lakes in your hometown? What color are they? Around one-third of the world's lakes are blue, according to a study in September 2022. But global warming may lead them to turn green or even brown, and countries with most lakes may be affected the most. If the temperature continues to rise, one in every ten lakes might change color.

Xiao Yang from Southern Methodist University in the US and his team analyzed (分析) the color of over 85,000 lakes based on the satellite photos taken from 2013 to 2020. The study has found that lakes in places with cooler summer average air temperatures-below 19℃-were more likely to be blue than lakes in places with warmer summers.

According to the research, the color of a lake is partly decides by what's in the water. Water molecules absorb the long wavelengths of sunlight, such as red and yellow, leaving behind the shorter ones presenting green and blue. Simply put, the cleaner the water, the bluer it looks.

Lakes serve as an important part of our environment, with their color being one of the oldest ways to determine the health of an ecosystem. Humans get their drinking water from lakes, streams and ground water. As they become greener, people may lose lots of clean water. Because of this, dealing with the water of such lakes becomes more expensive.

At the same time, blue lakes are also  a source of a place to help people stay peaceful. Some countries according to Catherine O' Reilly, even considered blue lakes as a spiritual(精神的) place. As these lakes disappear, they may feel upset.
