Hello, everyone!  1 to Class 3. I'm your new English teacher, Mr. Yang. Now let me tell you our class  2. First, you can't be late 3 class. You must 4 on time. Second, you must bring your English books and notebooks to every 5. Third, you must   6 English during the pair work activities. If it's 7 for you, you can ask me for help. Fourth, if you have any  8, you must put up your hands(举手). You can't talk or stand up without permission（未经许可）. These are all the rules. They are good for you,  9 you must follow them. I hope we can have a good 10 every day.

    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.

Doorbells are the bells (铃) for people to ring at a door. When someone hears it, he or she can open the door. Do you know that you can ring a doorbell for fish, too? 

Every spring, millions of fish migrate (洄游) along the river in the city to find better places to lay eggs. But in the river, there are many locks (水闸). They stop fish from swimming through. Weerd Lock is in Utrecht, the fourth largest city in the Netherlands (荷兰). When fish get there, they have to wait a long time before the lock opens for boats to pass through. The lock keeper there is glad to open the lock for fish, but he cannot tell when fish want to get through. So in 2021, Mark van Heukelum, a scientist, came up with a good idea to help solve this problem—by using the fish doorbell. 

Under the water near the lock, there's a camera. People from around the world can visit a website (网站) to see fish through the camera. When you see a group of fish waiting, you can ring the doorbell on the screen. And when the lock keeper notices it, he will open the lock for the fish. 

In its first spring season in 2021, people around the world rang the fish doorbell more than 100,000 times. If you want to join them to help fish, visit the website and ring the fish doorbell next spring. 

①Hello! My name is Emma and I'm eleven years old. I have a brother, Josh, who's just five. I live with my family on a farm in the southwest of England. I was born in London, but my parents moved to Devon when I was two. My brother was born here, in Northam. My father runs the farm and my mother is a vet (兽医). We have lots of animals on our farm like ducks, chickens, pigs, sheep, cows and horses.

②I love living in the country. I don't mind getting up early every day. I'm old enough to help my parents with the work on the farm. I love feeding ducks and chickens. It's not difficult at all. It takes me about a quarter of an hour to give them fodder every morning, but first I have breakfast myself. Sometimes I also help my dad milk the cows, especially on weekends.

③My brother and I go to a local primary school (小学). My mother always drives us to school and picks us up when lessons are over, at 3 o'clock.

④On Wednesdays, I have a karate (空手道) class so I go back home by bus. When I come back, I do my homework first and then help my parents with the animals or in the garden. We usually have dinner at six o'clock. After dinner, I often play computer games or watch TV. Before I go to bed, I always read for a while but not too long because I have to get up early the next day.
