练习7 To reach this conclusion(结论), they did an experiment(实验). The first group of the mice was in normal condition. But in the second group, they broke some smelling neurons(神经元) of several mice by using virus(病毒), so their ability to smell was “switched off(关掉)”. Both of the two groups were fed the same amounts(数量) of fatty food. At the end of the experiment, those with their smelling ability switched off had not put on weight, while the first group had put on the pounds. The researchers also showed that “supersmellers” mice put on the most weight.

练习10 (2024·湖北中考) ①So far, China has successfully sent a large number of satellites(卫星) and spaceships into space. Space scientists have been greatly inspired(赋予灵感) by the old stories and ancient famous people when giving them names.
②Since thousands of years ago, Chinese people have dreamed of going to the moon. Chang'e Flies to the Moon is one of the most popular stories. As you can see, China's first man-made satellite to circle around the moon was named Chang'e-1. More interestingly, the moon rover(巡视器) was named after the Jade Rabbit, who is the pet of Chang'e in the story. These old stories carry people's best wishes and dreams. With the development of science and technology, our scientists have made them come true.
③Kua Fu Runs After the Sun is another story to show how much ancient Chinese people wanted to know about the unknown world. Now, Kua Fu is going with the scientists to “visit” the sun, because we have a space project called Kua Fu Mission.
④Besides the ancient stories, space scientists also get ideas from ancient famous people. For example, Mozi, an ancient scientist, discovered that light travels in a straight line over 2,000 years ago. His discovery made space study take a big step at that time. So, China's first quantum(量子) science satellite was named Mozi, making China the first country in the world to achieve quantum communication between satellites and the ground.
⑤From such simple things as giving names to the satellites, we can see how great our traditional culture is and what influence it has on our modern science and technology.
