Delhi, one of the most polluted cities in the world, went into a strict lockdown (居家隔离) on the 24th March, 2020. A study team looked at the PM2.5 particle concentration (浓度) in the air at the US embassy (大使馆) in Delhi before and after the lockdown. They found the PM 2.5 particle concentration dropped by 46%.

The new study also looked at solar power (太阳能) in Delhi. It has found that the reduction (减少) in air pollution has allowed a lot more sunlight to get through to solar panels in the city.

Overall, the amount of sunlight reaching solar panels in Delhi increased by around 8% in late March 2020, and 6% in April 2020 compared to similar dates in earlier years.

How is it going? I haven't (hear) from you for a long time. I want to tell you something about housework. Parents nearly do all the housework. It is unfair for (they), I think children should share housework their parents. Here is my housework plan for this term.

First, I will make my bed take out the rubbish. Besides, I will clean the house every day to make it tidy. (two), I want to learn to cook. My mother is English teacher. She is usually busy. And she often (worry) about me when she is busy with work. If I can cook, she needn't worry about me anymore. I also want to learn many other (skill) to improve myself.

What housework do you (most) do at home? Let's share the housework together. Then we can have a (clean) house than before.

I hope to get your reply soon.

Then, the raven decided that he also wanted to have white feathers like the swan's. From that day on, the raven began to live like the swan. He moved his home from the woods to the lake. He also started to eat water plants like the swan. He tried his best to talk and dance with the other birds. The most important was that each day, the raven would wash his feathers, hoping that they would turn white. Even he went to the nearby rivers and ponds to wash his feathers because he thought the water in the lakes was not enough for him to wash them. But no matter how hard he washed his feathers, they remained black.

As he ate only water plants, he soon grew thinner and thinner. Not many days later, the raven died.

After a few minutes there is a very weak light in the east, and then I hear a bird singing. It sings very loud and very clear. "That's the robin (知更鸟)," says Jim. A few more birds start singing with the robin and Jim knows the names of them too. Half an hour later, there are more and more birds singing, and it's very loud! Suddenly, all around us the air is full of the sound of birdsong. This is the dawn chorus (晨鸣), and it's beautiful.

"Wow, this is amazing!" I tell Jim, who is smiling. "Is there a dawn chorus every morning?"

"Birds can sing any time of the year, but the best time is the end of winter and during the spring. This is when the birds sing most." "Really? So, why do they sing?" I ask.

"Well, there are two reasons," explains Jim. "Most of the songbirds who sing are males. They want to find a female (雌性) so they sing to show how strong they are. The females listen and choose the best singer! The birds also sing to tell other males to go away. They need their own area; they don't like sharing with another male."

I listen to the birds; the songs seem too much to me. "Do the birds sing a special song in the morning?"

"That's a good question," replied Jim. "The successful birds have many kinds of calls and songs. Sometimes they copy the songs of other birds. This makes it sound like there are many birds in that place already and other males stay away. Also, the female likes songs with different notes. Some birds, for example, the European wren, have songs that contain over 700 different notes per minute!" So, how does Jim know so much about birds? Well, he works as a volunteer for the Royal Society for the Protection of Birds. He is trying to help the birds live in the modern world. "More and more of the birds' habitat disappears every year. The sparrow, for example, was a very common bird in the UK, now it's in danger."

By now the sun is up and the birds are quiet. It's light, so they can start looking for food, they need a big breakfast after all that singing.

Once, Tony's father would go to London on business (生意) for a year. Before leaving, he told his wife to look after their son well. The woman had to get up earlier and did all that her husband did before. Two months later, she was so tired that she was ill. The young man got into trouble right away. He couldn't do housework. Even he didn't know where to get on the bus.

Yesterday, Tony's mother found his shoes were worn out (穿烂了) and told him to buy a new pair. But he didn't know how to choose right shoes. The woman had a sigh (叹息), gave him a shoe pattern (鞋样) and told him to buy shoes himself. With a policeman's help, he found a shop. The shopkeeper (店主) brought some shoes and asked him to choose. When he was trying on a pair, suddenly, he remembered something and took them off. The man was surprised and asked, "What's wrong?"

"I'm sorry. I've left my shoe pattern at home."

According to a study in Nature Climate (气候) Change, the number of most polar bears will1 rapidly (快速地) by 2080. There are two reasons. One is that the sea ice is melting (融化). Polar bears catch seals (海豹) to eat on the ice.2 ice, they have to stay on land. But there is no3 food on land to support so many polar bears. The animals could die from hunger. The other reason is that mother bears may not be fat enough to4 milk for their babies, so some bears could stop having babies.

Polar bears are5 land animals that eat meat on the planet. They help control other kinds of animals. Losing them would break the balance of their living place.

The Arctic is the6 to about 25,000 polar bears. Arctic sea ice usually melts in spring and summer, then grows in winter. But now, the7 is taking longer to grow back. Scientists say the Arctic is warming twice as fast as the rest of the planet.

The study also shows8 it is possible to slow Arctic melting. Greenhouse gases (温室气体) could lead to climate change. In order to avoid creating greenhouse gases, the world should try to stop burning coal and riding in cars.

Saving the bears is9 us. Holland, one of the writers of the study, says, "I believe there is hope, but humans need to act10 to make that hope come true." Let's take action to protect our earth and save polar bears.

The students' answers were2, from 20g to 500g. The teacher said, "It doesn't matter on the real weight. It3 how long you hold it. If I hold it for a4, it's OK. If I hold it for an hour, I'll have an ache in my right arm. If I hold it for a day, you'll have to help me call a5. The longer I hold it, the heavier it becomes. What we have to do is putting the glass down, and6 for a while before holding it up again."

"If we carry our burdens (负担) all the time, sooner or later, we'll be tired. The burden will7 become heavier. Sometimes we have to8 the burden in order to carry on."

"So after you return home from school tonight, take a9 to have a break. Forget your burdens."

"Whatever burdens you have, you should learn to10 yourselves for a moment. Life is short but amazing. Enjoy it!"

Do you want to do volunteer work but don't know how? Here are some ideas for you.

Helping your old neighbors

When people get older, it becomes harder to do many things. Old people living alone can also feel lonely. As a volunteer, you can do a lot to help the old in your neighborhood. You can visit and talk to them. And there is also much housework you can help with.

Helping the disabled

Many people with disabilities need help. Some of them even can't live on their own. You can volunteer to read books to the blind or deliver (递送) something for people who can't get around too well.
Helping poor families

Some families don't have enough money to buy food and clothes for their kids. Some people even have no place to live. To help these people, you can give clothes, food or money to, or raise money for, a charity (慈善机构).

Xu Keyi, a 37-year-old photographer (摄影师), developed an interest in taking photos of wild animals. When she was a child, she always (dream) of traveling with a camera. After university, she worked as a reporter, but then a special trip (complete) changed her life.

During a trip to Antarctica, Xu saw penguin (企鹅) parents protecting their babies from danger. It touched her greatly and she made a (decide) to become a full-time wildlife photographer. she has visited many places in the world, her favorite place to work is China. "Some amazing animals like green peafowls (孔雀) only live in (we) country," she said. Last year, Xu climbed a mountain in Yunnan to take photos of green peafowls. After waiting in the rain for hours, she finally heard a peafowl singing on the mountain. It was moment of breathtaking beauty.

Xu also encourages people (care) about endangered animals through her photos. After she shared photos of China's protected golden Kaiser-i-Hind butterfly online, more (volunteer) began to help protect these butterflies. "Many animals may disappear before people notice them," Xu says. "We should act much (early)." The photographer feels happy when seeing more young people play a part protecting the wildlife. Xu will continue showing the beauty of animals to the world through her camera.

Researchers at California Polytechnic State University(简称 Cal Poly) did a study. They studied the effects(作用) of birdsong on people walking through a park in the U.S. state of Colorado. Danielle Ferraro led the Cal Poly study.

Feraro said there could be an evolutionary(进化的) reason why we like birdsong so much. "The idea is that when we hear birdsong, it could mean that we are in a safe environment," she said. There could be many other reasons, too. Ferraro said that in some areas birdsong could also mean the arrival of spring and nice weather. "Bird diversity(多样性) could also mean a healthy environment," she added.

Ferraro and her team played recorded songs from a group of different kinds of birds. They did this in a park in Boulder, Colorado. Over several weeks, the researchers played recorded birdsong at certain times of the day and other times they did not. Then they talked with hikers(徒步旅行者) after they passed by. People who heard the recorded birdsongs reported a greater sense of happiness than those who heard simply the natural birds. The researchers said that both the bird sounds and bird diversity could increase feelings of happiness.

The research team did the study during the summer. Ferraro explained why this was important. "The spring is the most birds' breeding(繁殖)season. We didn't want to disturb(打扰) the birds too much."

There was something 3 with the showerhead in my house a few days ago. I didn't call someone to replace (替换) it—who knows 4 he would ask me to pay for it? So I bought a new showerhead and replaced it myself. It only took me several 5. Less than a cup of tea, I finished and felt 6. It worked well.

Such repairing work was so simple. As for my brother, he 7 hundreds of dollars each year with the help of online instructional (指导的) videos about repairing the TV set. Before that, he asked someone to 8 it in his house many times. Of course, it's not easy to do it by himself 9. But when he knew more about it, he did better.

Home repair can not only help us save money, but more importantly, it can help us do things more 10.

On the farm, I3 fifteen horses and sheep! I soon found I was a terrible "father", but I was very happy4 I made some great friends and also improved my French. Talking to volunteers from different countries helped me5 more about the world. I feel thankful to have had so much fun with many nice people because of volunteering!
