More and more people like keeping pets, so pet hospitals are usually very busy. Kind persons who love animals are needed to provide help in busy pet hospitals. Those vets (兽医) will teach them how to take care of the pets.

    Scientists think that pets will probably be much smaller because people in the future will live in much smaller space. Scientists are now working on making very small farm animals. The same thing might be done to make small cats and dogs.

    It's said that one day you might own a panther (豹) as a pet. Some scientists believe that they might have to start turning wild animals into pets since this might be the only way to save them from dying out.

    What about buying a robot to be a pet? This may sound silly, buy it could become true. Robot dogs have been made to sell. They are like real dogs. These pets might become more and more popular in the future.

    Lots of people want pets while they are on holidays. A hotel in Minnesota has solved this problem. They lend cats to their guests. Many experts (专家) believe that this idea will become more and more popular. It is very possible that in the future you will be able to order a pet, as well as room service, at a hotel.

    What time of day can you think most quickly? Are you a morning person?" Or does it take you a few hours to get your brain going? A lot of recent research suggests that we should pay attention to our body clock. It can tell us what time of day we can perform best at.

    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 your body's temperature rise quickly.

    But everyone's body clock is different and some are special. Morning people will get up early and work better early in the day." Evening people will work later, but work better towards 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 3p. m. and 6p.- m.-,- so it's better to exercise later in the day.

    Between noon and'4p. m. , people begin to pay less attention. This is because we think less quickly after, a big meal. Research also shows we become sleepy around 2 p.m. This is why people in Spain take a short sleep in early afternoon.

    Finally'it is best to eat when we' re active. This allows our body to burn calories (卡路里) better and stops our blood sugar levels from getting too high.

    One day, a woman took a bus with her son. The boy was about four years old. He ran on the bus and 1 up and down on the seat. There was a man next to them. When he saw it, he was a little 2 and told the boy not to run or jump, because it was very dangerous and it was also impolite (不礼貌). But the3said, "He is just a little kid, we shouldn't be so strict with a child." The man said to the woman, "4 we don't teach the kids now, they will not follow the rules in the future."

    Do you agree with the woman or the man? At 5, we have family rules. For example (例如), we can't6 on school nights. In the school, we also have school rules. We can't listen to music in the classroom. We 7 eat in the classroom. We must wear uniforms8 Monday to Friday. Parents and schools are sometimes strict, but remember, they make rules to help 9. We must 10 these rules.

Different weather makes people feel different. It influences health, intelligence and feelings.

In August, it is very hot and wet in the northern part of the United States. People there have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states have more heart trouble after the weather changes in February or March.

The weather can also influence intelligence. For example, in a scientific report, IQ of a group of students was very high when a very strong wind came, but after the wind, their IQ was 10% below. The wind can help people have more intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year（July and August）.

Weather also has a strong influence on people's feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot summer.

Low air pressure may make people forgetful. Research shows that people leave more bags on buses and in shops on low-pressure days. However, at about 18℃, people become healthier and stronger. People feel best at this temperature.

Are you feeling tired, forgetful or unhappy today? It may be the weather's problem.

Do you like to have any online classes? It is becoming 1 to take classes at home during the early 2020. All you need is a computer or a cellphone. However, most students don't seem to like online classes. A 2 shows that only 33% of over 1,500 students from 10 cities would take such classes.

Many students said it was difficult to focus(集中) on 3 while taking online classes. Lian Ruohan, 15, at the Affiliated High school of Peking University, said, "There are no real classmates sitting near me; no real teachers watching me. I can easily surf the Internet or do 4 things if I want to. It's harder to be always focused."

In order to avoid that, Lian will prepare a lot before classes to make sure she will learn 5 in class. She also pushes herself to communicate(沟通) with teachers about difficulties. She often 6 or answers questions while taking online classes.

Wen Jiayi, 14, at the Yucai Middle School, thinks online interaction(互动) isn't 7. "I have few chances to communicate with the online teachers, and they don't really get to know me. When I don't hand in homework, all I get is only a short telephone 8 instead of real care," she said.

However, Lian thinks online classes still have many 9. "It saves time and money compared to(和……相比较) taking official classes. Also, if I can't 10 some part of a lesson, I can watch it again to make it clear."

Gardening is a popular activity all around the world. But what about people who do not have the space to garden? Not to worry! Today, we will give you information about growing beautiful window boxes. 

Location and safety

Window boxes are not just for the outside edge of the window, they can also sit on other places such as, walls, porches, or front steps. This window box can be on the front steps to a home and the owners can entered their window boxes. 

But safety first: People do get killed by falling window boxes. Make sure your window boxes are safe so they will not come down in a storm. If you feel your window box could be unsafe, you can have an indoor window box.

Light and water

Before you choose plants, check your window box location for light and rain. Window boxes dry out faster than in-ground plants, so they need more water. And if a window box is close to a wall or other structure, it may not get enough rainwater. 

Even if all your windows get little sun, do not give up. You can get a great look using plants that love the shade. Many shade-loving plants like spiderworts and verbenas，have leaves in beautiful colors and interesting shapes. 

The "wow" factor

What gives some window boxes their "wow" factor while others are just so-so? Create a theme! This is a central idea for the plants. For example, you may have a window box that is all cactuses or all edible plants. Or you could select only purple violets or green basil, then you'll have a color-themed window box. 

Besides having a theme, upkeep is also important. You should cut off anything dead, water your window boxes often and change things a lot.
