Different weather makes people feel different. It influences health, intelligence(智力) and feelings.

    In August, it is very hot and wet in the southern part of the United States. People there have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states(州) have more heart trouble after the weather changes in February or March.

    The weather can also influence intelligence. For example, in a 1983 report by scientists, IQ(智商) of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% lower. The wind can help people have more intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year (July and August).

    Weather also has a strong influence on people's feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot summer. At about 18℃, people become stronger.

    Low air pressure(气压) may make people forgetful(健忘). People leave more bags on buses and in shops on low-pressure days. People feel best at a temperature of about 18℃.

    Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather's problem.

Lake Street School Big Day Out!

Dear Parents,

    We are happy to have our summer trip to the Children Movie Museum and the Sports Park on Thursday, July 11th (Grade Seven) and Friday, July 12th (Grade Eight). Students can learn lots of very interesting things about the cinema and how movies are made. They will also learn about many sports and their rules.

Meeting Time: 7:40 am

Leaving Time: 8:00 am

Meeting Place: at the school gate

Arriving Time: by 5:00 pm

    We have this trip for the students to learn outside the classroom and also have a good time with friends. Students need to take a pen and a notebook with them because they have to take notes about what they see. They also need to wear their school uniforms and sports shoes. Please tell them to follow the rules in the museum and the park.

    We will be eating lunch at the dining hall of the park. The cost of the trip is 40 yuan. It is for the bus ride and the lunch.

    If your child cannot come, please tell your head teacher by July 8th in your class teacher-parent WeChat group.

    Cars make our lives more convenient. But they can also be a problem. For example, fossil fuel (化石燃料) cars mainly cause air pollution.

    To improve the environment, many countries are developing electric vehicles (EVs,电动车). Among them, China is taking a leading role and has created the world's largest EV market.

    Last year, over 40 per cent of the 753,000 EVs sold in the world were sold in China, more than twice as many as the number sold in the United States.

    "Filling up a fossil fuel car with gas (汽油) is more expensive than charging (充电) an electric car," said Wu Hao, who bought an electric car this year.

    However, there are still some problems. It can be hard to find charging piles (充电桩) and the cars can't go far before being recharged.

    Some of these problems are being solved. In 2014, China had 31,000 charging piles. Now China has the world's largest EV charging network, with more than 450,000 charging piles in total.

    Developing EVs is one of many efforts that China has made to cut down pressure on its environment after the government promised to stop increases in carbon dioxide emissions (二氧化碳排放量) by 2030.

    "As China goes, so will the world's car industry," the Wall Street Journal said.

    Vienna is a beautiful old city on the River Danube in the center of Europe. It's the capital city of Austria and the center of European classical music. In the 18th century a lot of musicians came to study and work in Vienna.

    In the Strauss family, there were two composers called Johann Strauss: the father and the son. The father, Johann Strauss the elder, wrote and played music for traditional dances, called the waltz. His dance music made him famous all over Europe. The son, Johann Strauss the younger, was also very successful and popular. He wrote over 150 waltzes. In 1867 he wrote The Blue Danube waltz.

    Mozart was another very important composer. He was born in Austria in 1756. Before he was six, he played not only the piano but also the violin. His family took him around Europe and he gave concerts in many cities. He wrote hundreds of wonderful pieces of music. But he became very poor and died in 1791 when he was only 35. Like Johann Strauss, father and son, he was a great European musician, and many people still think his music is perfect.

Give water, save lives

A bottle of water may not seem like much to you, but thousands of bottles will be of great help for people who live in drought-hit(遭受旱灾) areas in China.

Since last autumn, there has been very little rain in Southwest China. Some places, especially in Yunnan, Guangxi, Sichuan, Guizhou, have experienced a serious drought. Crops (庄稼) died, the land cracked(裂开), and wells (井) and rivers dried up. More than 20 million people are having difficulty in finding safe drinking water.

After learning about the drought, many people around the country helped by giving water, money and other things.

Last week, every member of the Communist Youth League (共青团员) and Young Pioneers(少先队员) were encouraged to give one bottle of water to the drought-hit areas. Students in primary schools and middle schools quickly joined the activity. In Yuhua Primary School in Xi' an, 900 students bought over 1,000 bottles of water with their pocket money. They also wrote their wishes on the bottles.

The serious drought has also made students realize the importance of saving water. Students from Nanshan Middle School in Huizhou, Guangdong went on the street to tell people to take part in water-saving activities.

"I've heard that some children in drought-hit areas don't have enough drinking water. They have to drink muddy ( 含有泥土的 ) water. I feel really sad about that," said one student. "I decide to take a shower twice a week instead of every day to save water," he said.
