Many homes have cameras to protect them from danger.1..But the cameras do not know whether the person is a family member, a friend, a postman or a criminal(罪犯).

But a new camera made by a French company can recognize(辨别出)faces. It can tell parents at work that their children have returned from school, or that the mail has been sent to their home.

2..When family members enter a home, the smart camera "recognizes" them and sends information to the owner's phone. The owner can choose to see the video then or later.

3., the camera will send a waning sound on the owner's phone.

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

"On a Friday I was at work, having a big monthly meeting when my phone moved. At first I told myself4., but my phone was telling me there was a face that the camera did not recognize. Something was happening in my house! "

"I saw a person I did not know with his shoes on, which is not allowed in my apartment. I watched it on the video.5..I hurried back home as fast as possible and called the police on the way. Thanks to the smart camera, the criminal was caught soon, "said Damien.

A.But if an unknown person enters a home

B.I felt quite surprised

C.The cameras can tell the owners if someone has entered

D.Oh, it must be a wrong wan

E.It can also tell them if a stranger has entered their home

Upcycling is the process of changing old materials into something useful and often beautiful.

So, is it the same as recycling? No. Recycling takes materials -paper or glass-and breaks them down so their base materials can be reused to make a new product. When you upcycle an item, you are not breaking down the material, you are simply refashioning it. For example, you might make shoes out of old tyres. Also, the upcycled item is typically of the same, or even better, quality than the original(原来的).

Upcycling isn't a new idea. Some of the best examples of modern-day upcycling come from the 1930s to 1940s when families didn't have enough materials. In those days, things were repurposed over and over until there were no longer useful. For example, an old door can be changed into a new dining table. Saving is still a trend(趋势)today and a big reason why more and more people upcycle. But an even bigger reason for the rebirth of upcycling is its good influence on the environment.

Upcycling is green. The plain and simple fact of the matter is that upcycling is much better for the planet than throwing things away. When you upcycle, that's one item less that ends up on the waste mountain. Upcycling is also considerably more environmentally friendly than recycling, which needs energy or water to break down materials. Upcycling just needs your own creativity and effort. For example, Grace Robinson, from the UK, takes used tea bags and turns them into dresses, shoes and even hats.

There are two ways to support the upcycling movement. Sort through your recycling bins and create items yourself, or buy ready-made items from upcycled materials. Both ways do good to the environment and in returm, you get something that's both attractive and practical.

    Four students from National University have recently returned from Africa. For 10 weeks, they worked in Zimbabwe and Botswana as members of a program called Raleigh International.

Raleigh International, created in 1984, gives young people a chance to do volunteer work while experiencing other countries and their cultures. More than 30, 000 students from different countries have volunteered in a total of 40 countries.

Marisa Silvestri, 20, a business major(主修学生), traveled to Zimbabwe to work with a group. Their first project was helping farmers build electric fences(围栏)to keep elephants from destroying their crops. When elephants entered the village one night, the students joined farmers to drive them away and protect the fields. Silvestri's group also built small houses in the local style for tourists to stay in.

Saeed Mohammed, also 20 and an engineering major, joined another group in Zimbabwe. His group carried out a survey of health problems in several villages and taught children about good health habits. Mohammed said after the health lessons, the kids asked them questions about "everything else under the sun".

    The epidemic(疫情)has changed our lives. It not only forces us to stay at home, but also changes the way we work, study, and even go shopping. In many countries, the Novel Corona Virus Disease(COVID-19)has also changed the way people greet each other. To help stop the spread of disease, people give up their usual greeting styles and invent safe ways. Let's take a look!

Lean forward, touch cheeks(脸颊)and make a kissing sound. This is French people's favorite way of greeting. It's very romantic. But when facing the virus, kisses are not good. Etiquette expert(礼仪专家)Philippe Lichtfus gives people a suggestion: simply looking into a person's eyes can be a greeting. It's not so romantic but it's safe.

Like the French, Italians are also romantic people. When they meet, they always hug or kiss each other. Recently, an Italian grandma made a video to help everyone fight against the disease.

She says that if you meet, you can close one of your eyes and give them a wink. Isn't it cute?

It's a very Australian thing to shake hands. But if you do this, the virus can jump from one person to another. Now a health official in Australia says a pat on the back would be better. But it also has some problems. For example, it's a bit crude if you do this to your teachers.

A video shows that an interesting greeting way is now popular in Iran. In the video, 3 Iranians meet and tap their feet against each other. They wear masks with their hands in their pockets. It looks like they are playing a fun game. If we can't shake hands, why not try to "shake" feet?
