A new camera made by a company named Netatmo has facial recognition software (人脸识别系统) that can tell parents at work that their children have returned from school, or that a package (包裹) has been taken to their home. It can also tell them if a stranger has entered their home.

    Janina Mattausch is a product marketing manager for Netatmo.

    "The common security (安全) cameras at present are not that smart. So, they can tell you if something is moving but they don't necessarily know if it's a human being or, ah, if it's your kid- they don't know the difference, so they will warn (警告) you all the time."

    When family members enter a home, the new camera "recognizes" (识别) them and sends information to the owner's smartphone. The owner can choose to see the video then or later. But if an unknown person enters a home, the camera will send the owner a warning that will cause an alarm to sound on the owner's smartphone.

    That is what happened recently to a smart home camera owner named Damien. He lives in Paris.

    "On a Friday I was at work, attending a big monthly meeting when my phone warned. At first I told myself 'Oh, it must be a mistake, maybe I have to set the system again.' —but the notice on my phone was telling me that there was a movement in my flat and also a face that the software did not recognize."

    He watched the video and was very surprised by what he saw.

    "I saw a person I did not know with his shoes on. I was watching it live on video. So I felt totally unbelievable, frozen. I asked a workmate to take me back home as fast as possible and I called the police on the way."

    With the help of the video, the police found the intruder (闯入者) later that day.

I'm Peter. My family will have a sale at my yard on Saturday. It will be from 10: 00 am to 6: 00pm. We have lots of things on sale because my parents want to make our house look new. 

l want to sell my bookcase(书柜). It's orange, my favourite colour. But it is too small for me. I have lots of books about history and science. I have no place to put them. 

l also want to change my chair, because it's uncomfortable and I don't like the green colour. And I have to sell my desk too. It is the same colour as the chair. My yellow curtains(窗帘)don't look very good. They are old. I hope to have new curtains. I also want to sell my old brown bed. But my parents don't think it is OK.

Are you free this Saturday? Please come to my house and have a look. 

Have you seen Avatar（《阿凡达》）? It's a popular 3D movie, and you may have to wear 3D glasses to see it. The 3D glasses make the images（图像）from the movie look as if they were coming straight towards you. 

More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies more exciting. However, people with eye problems may get headaches if they spend too much time watching 3D movies. Why?

When we look at an object（物体）, each eye sees it at a different angle（角度）. Our eyes send the two images to our brain（大脑）, and the brain puts them together. 3D technology uses two film projectors（投影机）. One projects a left-eye-image and the other projects a right-eye-image. 3D glasses allow us to see a different image in each eye. So, when we are watching a 3D movie, our brain can't put together the images sent to our eyes. The brain needs to work harder at "reading" the images. That makes it easier for people with eye problems to get dizzy（头晕的）or have headaches. A famous eye doctor said if your eyes can't focus（聚焦）on the same object at once, you will have trouble watching 3D movies. 

Dear Cindy,

Here are some of my favorite photos. Look at this photo! I am   1  a bookstore. I am reading a book. The story is not interesting. I want to play basketball outside,  2  I can't, as the weather is terrible. It is   3  . In the next photo, it's   4  . I'm playing with my sister in the snow. We are   5 sweaters and gloves(手套). It is very   6  , but we are still having a great  7  . Look, we are making a cute snowman. How interesting it is! What about the last photo? I'm   8  my grandparents at the train station. They are coming to my house. I'm surprised to   9  a young man across from the station. He is playing the guitar and singing beautiful songs. Lots of people are giving him   10  . Why is the young man doing that? He is raising money(募捐) for the old who need help!

Yours,

Andy

Cai Xuzhe dreamed of flying high when he was young. He was a new face on the Shenzhou-14 team. He spent 12 years as an astronaut（宇航员） getting ready for his first trip to space.

"I am happy and proud but feel more about my duty（责任）," Cai told reporters. Cai and other two team members, Chen Dong and Liu Yang, left the earth on board the Shenzhou-14 spaceship in June of 2022, for a six - month stay in space. They finished the work of building the Tiangong space station.

Cai was born in 1976 in the countryside of Shenzhou City, Hebei Province. He showed interest in planes as a child. When he heard a plane flying past, he ran out and looked at it till it flew away.

Cai went to an Air Force flight college（空军飞行学院）. After finishing college, he began to work at an airport. The airport was in poor condition. However, he studied and trained his flying skills there carefully. InMay 2010, Cai became a Chinese astronaut and underwent（接受） hard training. He did best in his training and finally became a Shenzhou-14 team member. He tried his best to make his dream come true.
