During the day we work and play, and at night we sleep. Our body rests when we sleep. In the morning we are ready to work and play again. Our body grows when we are sleeping.
Children usually need sleep, too. We can do better in our work after having a good rest. Boys and girls who are eight or nine years old need ten hours of sleep every night. Our body needs enough air when we are sleeping. If we don’t get enough fresh air, we will feel tired when we wake up(醒来). While in bed we must not cover(盖住) our head, our lungs need to get enough fresh air. If we open our windows at night, we can get lots of fresh air. Cool air is better than warm air.

【推荐1】What time of day are you quick to think or act? Are you more of a morning person? Or does your brain need a few hours to get going? A lot of research suggests that we should pay attention to our body clock. It can tell us what time of day we are best able to perform, according to the Wall Street Journal.
When it comes to the human brain, many people work best later in the morning. This is because the body’s temperature takes time to rise through the day. Taking a warm shower when you wake up can help speed this up.
But everyone’s body clock is different. Morning people will rise early and work better early in the day. Evening people will wake later but their brain will work better toward the end of the day.
Research shows that we’re better at some activities at certain times of the day. Physical performance is at its best between 3 pm and 6 pm, so it’s better to exercise later in the day.
Between noon and 4 pm, people are getting tired. This is partly because we are slow to think or act after eating a big meal. Research also shows that we become sleepy around 2 pm.
Finally, it is best to eat during our active periods. This allows our body to burn calories better and stops our blood sugar levels from getting too high.
1. Many people perform best later in the morning because ___.| A．they can’t get up very early | B．the body’s temperature needs time to rise |
| C．they have to take a shower first | D．that’s when the brain wakes up |
| A．rise early and work in the morning | B．rise late and work in the morning |
| C．wake later and work better in the evening | D．wake later and work after midnight |
| A．It’s better to do exercise in the afternoon. | B．We perform better after eating a big meal. |
| C．Sleeping at 2 pm is not good for our health. | D．Our body burns calories better at night. |

【推荐2】Many people have taken part into lots of virtual (虚拟的) meetings these years. Some research shows this might not impact workplace productivity to any great degree. A new study, though, suggests otherwise.
In the study, 602 participants were paired and asked to come up with creative uses for a product. They were also selected to work together either in person or virtually. The pairs were then ranked by their total number of ideas, as well as those ideas’ degree of creativity, virtual pairs came up with significantly fewer ideas, while face-to-face interaction gave more creative ideas. The findings could stiffen employers’ determination to urge or require their employees to come back to the office.
“We ran this experiment based on feedback from companies that it was harder to innovate (创新) with remote workers,” said lead researcher Melanie Brucks. “Unlike other forms of virtual communication, videoconferencing copies the in-person experience quite well, so I was surprised when we found meaningful differences between in-person and video interaction for idea generation.”
When some objects were placed in both the virtual and physical rooms, the virtual pairs of participants spent more time looking directly at each other rather than looking around the room and taking in the entire scene. Eyeing one’s whole environment and noticing the objects were closely connected with increased idea generation. On platforms, the screen occupies our interactions. We don’t see around. “Looking away might come across as rude, so we have to look at the screen because that is the defined context of the interaction, the same way we wouldn’t walk to another room while talking to someone in person.”
Like most educators, Brucks has taught virtually in the past three years, and she did notice some benefits of the approach as well. Her students were more likely to take turns speaking and her shyer students spoke up more often, for her students felt “freer” and more creative when asked to do so. And this may be sound advice for the workplace.
Virtual teamwork can’t replace face-to-face teamwork. Idea selection proficiency (能力) is only valuable if you have strong options to select from, and face-to-face teams are the best means to generate winning options. Perhaps the workplace will find a sweet spot in the middle that balances working from both home and office.

【推荐3】Qomolangma is the world’s highest mountain. You may have learned from your textbooks that its height is 8,844 meters. But not all sides are in agreement on this. Different researchers have given different results. In addition, the height of the mountain can change over time.
That’s why a 30-member Chinese survey team set out to reach the peak (顶峰) of Qomolangma to re-measure its height on May 6. They are equipped with the latest technology, including a global navigation satellite system receiver and a radar (雷达).
It is not an easy task. The average air temperature on the mountain is —29℃—four degrees lower than in Antarctica (南极洲) -and powerful winds blow all the time. In such bad conditions, surveying drones (无人机) cannot work at the peak of the mountain. That’s why it’s still necessary to send human experts to the peak to get believable results.
But does a difference of a few meters really matter when it comes to a high mountain?
In fact, measuring the height of Qomolangma is about more than just getting one exact number. Mount Qomolangma is at the point where the Eurasian plate meets the Indian plate. It formed 38 million years ago as the two plates hit each other. Changes in the peak’s height can show whether the two plates are heading toward or away from each other. This can help us understand the movement of Earth’s crust (地壳).
The survey team will also get firsthand information about environmental conditions at the top of the mountain. This will help us understand how climate (气候) change has affected the Tibet-Qinghai Plateau (高原).
1. We can know that ________ in the first paragraph.| A．the height of Qomolangma increases every year |
| B．there is no agreement on the height of Qomolangma |
| C．it’s not easy to measure the height of Qomolangma |
| D．researchers measure the height of Qomolangma every year |
| A．the average air temperature is lower than that in Antarctica |
| B．powerful winds blow all the time in Antarctica |
| C．there’s no difference measuring the height by the experts or not |
| D．few people can stand the conditions on the mountain |
| A．explore the bad conditions | B．fix the receiver and the radar correctly |
| C．make sure the drones work in control | D．get believable information |
| A．the Eurasian plate | B．the Indian plate |
| C．Mount Qomolangma | D．the Earth’s crust |
①the movement of Earth’s crust
②how the height changes
③how climate change has affected the Tibet-Qinghai Plateau
④how we can overcome the bad conditions in life

【推荐1】Tenzing Norgay and Edmund Hillary reached the top of Qomolangma in 1953. It was an important event in the mountain climbing history. Also, it was a turning point in the lives of Sherpa (夏尔巴) people.
Before 1953, Sherpa people led a very simple and peaceful life. Most of them worked on farms. They had very little connection with people from other parts of the world. Now things have changed, and thanks to technology, the Sherpa world is much better connected. Tourism (旅游业) is also a main force in changing the lives of Sherpas. After 1953, especially in the 1970s, the number of tourists to Nepal (尼泊尔) increased greatly. Today, tourism is the biggest source of income (收入来源) for Sherpas. Many Sherpas now have a richer life.
Back in 1953, education and health care in Sherpa villages were poor. These days, however, there are many schools and medical clinics (医疗诊所). Changes have also come to Sherpas dinner table: they eat healthier food than they used to. They can also get food from other places. Besides, they are able to get and use quality building materials (建筑材料). The new buildings are much safer than they used to be.
There are some Sherpas, however, who like the old way of living their lives. Some older Sherpas are upset that people seem to be moving away from the traditional way of life. They believe that some Sherpas these days think too much about money. As a result, they are losing the ability to pay attention to true happiness.
1. Now Sherpa people make money mainly by ________.| A．serving tourists | B．building houses | C．doing farm work | D．selling medicine |
| A．廉价的 | B．优质的 | C．轻巧的 | D．传统的 |
| A．should make more money | B．have found true happiness |
| C．are becoming less traditional | D．should pay more attention to nature |
| A．Tourism in Nepal | B．Changes in Sherpas’ lives |

Little Scientist Dancing Paper Scraps (碎纸屑).
If you’re looking for a fun and easy science experiment to do at home or in the classroom, the dancing paper experiment is perfect! It’s a great way to learn about static electricity (静电) and how it works. It’s not only simple, but also really fantastic! What you need:A balloon, paper scraps, a plate Instructions:Step 1: Before you begin, make sure that your balloon can inflate as easily as possible and tie the end. Step 2: Place the paper scraps on a plate. Step 3: Rub (摩擦) the balloon against our hair again and again. Step 4: Place the balloon above the paper scraps. Result:The paper scraps start dancing in the air! Why? This means there are more positive (+) or negative (-) charges on its surface than normal. The negative charges attract the positive charges in the paper scraps, making them move towards the balloon. Try this! If you have long hair, try this with your friends. Rub the balloon against your hair, then hold it near your friends’ hair without touching it. Their hair will stand up! |
1. What do you need for the experiment?
| A．A pencil, a plate and some paper. | B．A plate, a balloon and paper scraps. |

【推荐3】①In December 2021, people found that water ran more slowly from their taps. The government (政府) said the city was facing its most serious water shortage ever.
②Some other cities in the southern part of China, like Chengdu and Guangzhou, are also becoming “thirsty”, the Paper reported. Compared (相比) with northern areas, southern areas have more rain and are close to more rivers and lakes. So why are they still short of water?
③In big cities like Shenzhen and Guangzhou, populations are growing fast. As a result, people and factories need more and more water. Each person in Shenzhen has about only 200 cubic meters of water each year. It’s 1/12 of the country’s average (平均水平). According to the United Nations, it is an “absolute (绝对的) water shortage” when the number is below 500 cubic meters.
④Climate change is making the water problem worse. For example, most cities in Guangdong depend on (依赖于) the Dongjiang River as their main source (来源) of water. In 2021, the river was reported to be drying up. Because of climate change, there’s also less snow in the mountains of Tibet. The snow has long been the source of water for many areas in China. Those mountains might provide less water in the future.
⑤There are other reasons for water shortages. For example, water pollution makes it harder to get clean drinking water. Factories and farms don’t use water efficiently (有效地). Some cities have enough rainfall, but don’t have big lakes or reservoirs to store water. The water just goes into the sea.
1. What does the underlined word “shortage” mean in the FIRST paragraph?| A．having too much | B．not having enough |
| C．being too small | D．being too dirty |
| A．Growing populations. | B．Cutting down forests. |
| C．Climate change. | D．Water pollution. |
A． | B． | C． | D． |
| A．To talk about terrible results of water shortage. |
| B．To call on people to protect water resources. |
| C．To blame people for causing water shortage in China. |
| D．To show some reasons of water shortage in China. |
