（2022·广西·三模）The Beijing 2022 Winter Olympics were not only a sporting event but al
夏季旅游so a show for science and technology. High tech gear (设备) is helping athletes become “faster, higher, stronger”. Let’s look at some.
The fastest ice | The National Speed Skating Oval is said to have “the fastest ice”, as 12 new Olympic records and one world record were t there. The cret is new ice-making technology. Liquid carbon dioxide (液体二氧化碳) is put under the ice to keep temperature changes on the ice surface in half a degree. That keeps the ice flat. |
“Seeing” the wind | In events like freestyle skiing, ski jumping, the direction and speed of the wind can have a big effect on an athlete’s performance. A Chine rearch team develops a system to measure (测量) wind. The system us AI technology. It allows athletes and coaches to “e” wind with real-time data on their pads, and decide when and where to jump. |
Fresh air | 黄花菜的功效 As COVID-19 can spread through the air, clean air is key to keeping fans, workers and athletes safe and healthy. The Winter Olympics u large air purifiers (净化器) to catch and kill bacteria in the air and make sure that clod venues always have fresh air. |
Smart “Band Aid” | A wearable thermometer (温度计) can measure the body temperatures of fans and athletes. People can wear it on their upper arms to monitor (监测) their temperature in real time. It will nd a warning if somebody’s body temperature goes higher than 37.3 degrees. |

（2022·湖北武汉·二模）Chang’e 5 completed its task successfully in 23 days, not only did it return with valuable rock and soil samples from the moon, but also brought back a group of eds that traveled the furthest in China. More than 30 kinds of eds, including that of rice, oats etc., were placed inside the Chang’e 5 spacecraft and went around the
moon for about 15 days.
Scientists wished to check what would happen to the eds after the task. This task offered good opportunities to scientists, which helped them to deepen their studies on the effect of cosmic rays (宇宙射线) on the growth and development of life on Earth.
Space-bad mutation breeding (太空诱变育种) refers to the process of placing eds in the environment such as microgravity (微重力), vacuums (真空) and cosmic radiation (宇宙辐射) during a spaceflight and then nding them back to Earth for further study and planting. Scientists study and examine veral generations of plants grown from eds which went into the space and study their changes-some are desirable while others are bad and negative. Tho with good changes will be kept for further rearch, and will be introduced to farmers after getting permission.
Space breeding (育种) can make the eds change faster than the experiments on the earth and can bring about some wonderful results. Compared with the traditional methods, space-developed methods can make the eds grow much better, such as havi
ng shorter growth periods and having more power to fight against dias and inct.
China did its first space breeding experiment in 1987, using a satellite to carry eds into space. Since then, hundreds of kinds of eds and edlings have traveled with dozens of Chine spaceships. Space breeding has helped to produce more than 200 new types of mutated plants in China that have been allowed to be planted across the country from grains to vegetables and fruits.
The Chang’e 5 brought back 1, 731 grams of moon’s rock and soil to Earth, showing a historic achievement 44 years after the last moon’s rock and soil were taken back.
6．Why were the eds placed inside Chang’e 5?
A．To pick out the best eds.
B．To understand the environment of the space.
老友记mp3打包下载C．To study the cosmic rays.
D．To put them in a special environment.
7．The underlined word “desirable” in paragraph 3 is probably clost to in meaning ________.
A．wor B．good C．uless D．correct
8．What can we learn from the last paragraph?
A．Chang’e 5 flew around the moon for about 23 days.
B．China was the first to do a space breeding experiment.
C．It is some time since eds were last taken into space.
D．Space breeding is good for farming.
9．From the passage, we can infer that ________.
A．space breeding is the best way to develop the eds
B．China is the first country to do space breeding experiment
C．China will spend more time and energy on space breeding
英文论文网D．Chang’e 5 spacecraft will fly to the moon again
