Record fires sweeping across the Amazon recently have been making the headlines as scientists and environmental groups are worried that they will worsen climate change crisis and endanger biodiversity(生物多样性）。
As the largest rainforest in the world, the Amazon is often called"the lungs of the world”. It is also home to about 3 million species of plants and animals, and 1 million local people. The vast area of rainforest plays an important role in the world's ecosystem because it absorbs heat instead of reflecting heat back into the atmosphere. It also stores carbon dioxide and produces oxygen, ensuring that less carbon is released, reducing the effects of climate change.
＂Any forest destroyed is a danger to biodiversity and the people who use that biodiversity," Thomas Lovejoy, an ecologist at George Mason University told National Geographic."The great danger is that a lot of carbon goes into the atmosphere,"he stressed."In the midst of the global climate crisis, we cannot afford more damage to a major source of oxygen and biodiversity.The Amazon must be protected,"UN Secretary General Antonio Guterres said.
Data from the National Institute for Space Research(INPE)show that the number of forest fires in Brazil quickly increased by 82 percent from January to August a year ago.A total of 71,497 forest fires were registered in the country in the first 8 months of 2019,up from 39,194 in the same period in 2018,INPE said.＂We estimate that the forest areas in the Brazilian Amazon have decreased something between 20 and 30 percent compared to the last 12 months," Carlos Nobre, a researcher at the University of Sao Paulo, told German broadcaster Deutsche Welle.
Brazil owns about 60 percent of the Amazon rainforest,whose degradation(恶化）could have severe consequences for global climate and rainfall.The extent of the area ruined by fires has yet to be determined, but the emergency has gone beyond Brazil's borders.

Almost everyone has heard the expression “the calm before the storm”. It is usually used to describe a peaceful period just before a very stressful situation or a tense argument.
British sailors created the phrase in the late 1600s. They noted that before certain storms the seas would seem to become static and the winds would drop. But why is it often so calm before a storm?
Science has given us the answer. According to US website How Stuff Works, a calm period occurs because many storms, such as hurricanes and tornadoes (龙卷风), draw in all the warm and damp air from the surrounding area. As this air rises into the storm clouds, it cools and acts as “fuel for the storm, like petrol in a car”.
Once the storm has taken all the energy it can from the air, it is pushed out from the top of the storm clouds and falls back down to ground level. As the air goes down, it becomes warm and dry. Warm, dry air is stable, so once it covers an area, it causes a calm period before the storm. This same process also causes “the eye of the storm” in hurricanes and tornadoes. In these conditions, the calm occurs in the center of the storm because of the strong winds moving in a circle.
The Weather Network has a tip for working out how far away a storm is. First, count how many seconds there are between a flash of lightning and a clap of thunder. Roughly 3 seconds equal 1 kilometer. So, for example, if you count 9 seconds, the storm is about 3 kilometers away. A good judgement is that if your count is below 30 seconds, you should seek shelter straight away.
However, due to the complexity of storm system, not all storms break after calm. Given the right conditions, some storms announce themselves with heavy rain and cold winds.
So, your best bet is to keep yourself updated with weather reports for any predictions regarding a coming storm in your area. That’s the most reliable and sensible way to predict the next display of nature’s temper.

I’m now living in the south of France with my husband Keith and three small children, and I feel like a fish out of water everywhere but one place — the Saturday street market. It’s been operating in our small town of Sommieres since the 13th century, but we’ve only lived here for three months.
From Monday to Friday, life is all about the kids. I’m busy helping my children deal with life in a French school. It’s not easy, and their stress is the whole family’s stress, as Keith and I are occupied with the daily school runs, piles of homework and school notes in French.
But on Saturday, the market is for me. I feel so peaceful as I walk along the quiet street toward the busy town square. The knife-sharpening man is there, operating a machine that looks like it dates from the Industrial Revolution. There’re street musicians with guitars and microphones, and the sound of beautiful songs fills the air. And the food, of course, is delicious. The cheese man doesn’t speak — he just points and cuts, offering a piece from his knife. Lines come out of the door for fresh bread at the bakery. Organic vegetables, herbs and desserts are a feast for the eyes, before being put into the bag to be enjoyed later for lunch. The noises and smells of the market are unfamiliar and thrilling, but their procedures are clear to me. This is part of why I love the place so much: Unlike during the week, when I’m constantly faced with my own difficulties, I know how this place works. My terrible French isn’t the barrier to communication that it is in other circumstances.
At school and in the village, I can’t joke or join a conversation, and although the other parents at the school are kind, I’m an outsider. But at the market, I’m just another customer with a basket. Surrounded by day trippers, I feel like a local — greeting people I know and petting dogs.
My Saturday experiences allow me to hope that in the near future I’ll feel equally confident in my everyday life. Until then, Saturdays prepare me for the coming week of school runs.

I was 11 years old when I asked my mom for piano lessons in 2010.We were in financial trouble,so she said politely,"Sorry,son,but we can't now.”
I googled the measurements for a keyboard,drew the keys on a piece of paper and stuck it on my desk.I would click notes on an online keyboard and"play"them back on my paper one-keeping the sound they made on the computer in my head.I spent 6 months playing without touching a real piano.Once my mom saw that I was serious,she borrowed money and bought me 10 lessons.
I still remember the first one.I was struck by how real the sound of the piano was.I sat my Grade 1 after 8 lessons.Once I started secondary school,we couldn't afford lessons again.I passed Grade 3,and then Grade 5,practicing only on my piece of paper.One evening,when I was about 13,my mom said she had a surprise for me-it was an electronic keyboard,bought with more borrowed money.It was the first time that I'd played for her and she was in shock.
My school didn't offer music A-level.I found the Purcell School for young musicians,but the tryouts were difficult.Some of the questions even involved an evaluation of the composer.I was at a loss.But to my amazement,I was offered a place.At Purcell,I spent 2 years working as hard as I could.I performed to raise money and saved enough to buy my first piano.When I left Purcell,I was awarded the senior piano prize and academic music prize.I'm now at the Guildhall School in London.I feel proud-it's been 10 years since I drew my paper piano,and I'm at one of the world's leading music schools.
Surprisingly,I continue to do a lot of my practice away from the piano:what we call mental practice.The paper piano helped motivate my curiosity about how music works.

The other day we take our school bus to the nearby nursing home. The elderly people greeted us warm and they were really very pleasing to see us. There we did a lot things. We told many interesting stories to them or sang and danced for them and we really had a fun. Around 11 o’clock in the morning they returned to the school. As student, we are very fond of the activity. It’s our duty to helping the elderly people, in my opinion. How a meaningful trip it was! We’ll never forget it.
