    Getting electricity has always been a problem for the 173 people living in Nuevo Saposoa, a small village in Peru, South America, However, things went from bad to worse in March 2016 after heavy rains damaged the only power cables in the area. The villagers were forced to use oil lamps, which are not only expensive but also dangerous because of the harmful gases they produce.

    Luckily, researchers at the. University of Technology (UT) in Lima,Peru heard about their problem and found a wonderful solution, They made a lamp that can be powered by plants and soil, both of which can be easily found in the Amazonian rainforest where the village lies. T he lamp takes energy from a plant growing in a wooden box and uses it to light up an LED light bulb.

    While that may sound amazing and even impossible. the science behind the idea is quite simple. As plants create their food (using the sun's energy, water and chemicals from the soil), they also produce waste which they return to the soil. Tiny animals in the soil eat this waste and they produce electrons 一 the building blocks of electrical energy. The UT team put special sticks inside the soil to capture the energy and keep it in the lamp's batteries for later use. The researchers say a single charge can power a 50 一 watt LED light for two hours 一 enough time for local villagers to get their evening work done.

    The university gave ten plant lamps to the villagers of Nuevo Saposoa in October 2016. So far, they have been a huge success! Elmer Ramirez, the UT professor who invented the lamp, believes the plant lamp could help improve the lives of many people, especially small rainforest communities, 42% of whom have no electricity.

Do you want to write a story? Ask ChatGPT and you will get the story just one second later. If you write"a girl wants to go to Australia", you will get the story of Alice, who goes through many difficult things to travel to Australia.

ChatGPT is made by the US company OpenAI. It came out in November 2022. It changes the Internet in a very short time. People can ask it to write stories and emails, answer all kinds of questions and even do homework. In its own words, it is"a big language model* which helps users to write anything they like."

Different from Siri, ChatGPT uses a much bigger database*. It can also learn things by itself. For example, if it gives a wrong answer to your question, you can tell it the right one and it can make changes. "It's a really great product!"Liu Xiaoguang, a computer scientist from China, says,"Its level is the sameas an undergraduate* student's. That's why it surprises the world."

But one big problem with ChatGPT is that it cannot give right information all the time. Rezza, a 28— year—old English learner from France, uses ChatGPT to write a passage."It gives little useful information", he tells a newspaper. Besides, some students will learn nothing if they always use ChatGPT to do homework.This is because they won't think by themselves. So we should be careful to use ChatGPT.

What is the future of ChatGPT? Maybe scientists need to work more on it.

 阅读下列短文,从每题所给的四个选项(A、B、C、D)中选择最佳选项。

We all enjoy the colors of autumn leaves. Did you ever wonder how and why a leaf changes color?Where do the yellows and oranges come from?To answer those questions,we first have to understand what leaves are and what they do. 

Leaves are the world's food factories. Plants take water from the ground through their roots and take CO2 from the air. Plants use sunlight to turn water and CO2 into glucose(葡萄糖),a kind of sugar. Plants use it as food for energy and growing. 

A chemical called "chlorophyll(叶绿素)" in the leaves gives plants their green color. As summer ends and autumn comes,the days get shorter and shorter,and trees "know" it's time to begin getting ready for winter. 

During winter,there is not enough sunlight or water. Trees rest during this time and live on the food they store during the summer. They begin to shut down their foodmaking factories. As the green chlorophyll disappears from the leaves,we begin to see yellow and orange leaves. 

The bright reds and purples we see in leaves are made mostly in autumn. In some trees,like maples(枫树),sunlight and the cool nights of autumn turn the glucose in the leaves into a red color. And we can enjoy the beautiful red leaves during autumn.
