There are many expressions with heart. One of them is "lose your heart to someone". When that happens, you have fallen in love. But if the person who "won your heart" does not love you, then you are sure to have a "broken heart". In your sadness, you think that the person you loved is "hard-hearted", and in fact, has a "heart of stone".

    You may decide to "pour out your heart" to a friend. Telling someone about your personal problems can often make you feel better.

    If your friend does not seem to understand how painful your broken heart is, you may ask her to "have a heart". You are asking your friend to show some sympathy(同情) for your situation. Your friend "has her heart in the right place" if she says she is sorry for how you feel.

    If your friend says, "My heart bleeds(流血)for you", she means the opposite. She is a cold—hearted person who does not really care about your situation.

    When you are feeling afraid, "your heart is in your mouth". You might say, for example, that your heart was in your mouth when you asked a bank to lend you some money to pay for a new house.

    If that bank says no to you, do not "lose heart". Be "strong-hearted". Sit down with the banker and have a "heart to heart" talk. Be open and honest about your situation. The bank may have a "change of heart" and agree to lend you the money. Then you could stop worrying and "put your heart at rest".

Nowadays in school life, a lot of students develop a fear of tests. It's not because tests are something to be afraid of. Most students are afraid of tests mainly because they don't always think they are well—prepared and they don't have enough self—confidence. If you follow the advice below, it's not difficult to overcome your fear of tests.

People who know that they are not well—prepared are usually those who fear tests most. However, most students don't know when they are truly prepared for a test. As long as you know that you have studied well and long enough, you have reason to believe that you are well—prepared.

Be confident about yourself. Confidence before a test can bring about two results: either you fail the test and feel as if your confidence was unfounded (毫无根据的) or you could actually do well in the test because of your confidence. Some students find that they experience the first result. However, this is only because those students might not have followed the first advice mentioned above. As long as you have studied well, you will be more confident of your chance to succeed in a test. If you feel as if you have not studied hard enough, then you will not be as confident as you should be.

Ask your teacher in advance (提前) about the material that is going to be covered in the test. In this way, you will know what you should prepare for and you can get confidence in the test. But you have to be brave enough to ask. Most students do not ask unless their teacher gives the information first, so make sure that you ask.

You should know that tests are only telling if you have got the knowledge, not how good or bad your IQ is. So, even if you do badly in one test, you should know that there are other tests to come. As long as you think that there is another tomorrow, you can overcome your fear of a test. However, make sure that you are going to prepare well for the other tests.

Fear can be a problem in the process of achieving success. However, with the right attitude (态度) and preparations, you can overcome your fear of tests by using these suggestions.

Hello, I'm Li Hua, born in 2000. I have seen the rapid 1 in my city myself. When I was born, I lived in a two-floor 2 . Now my family moves to another tall building with big rooms. In 2004, my father bought 3 the first mobile phone. He could call his friends or 4 messages to them. But since 2006, he has 5 5 other phones. The new technology has made the cellphones a necessary part in our lives. They are 6 to use now. When I was young, we must buy objects with 7 . But now a smartphone helps us pay for goods in the markets. For the 20 years, the number of the cars has increased 8 . We can see more and more ordinary people 9 cars or planning to buy cars. So there are fewer and fewer bikes on the road. With the development of China, people's living conditions are 10 better and better. 

Have you heard of depression(抑郁症)? It's a mental illness. People who have it may feel轮sad all the time or do something to hurt themselves. Now, doctors can put a"happy switch(开关)" in their heads to help them. The "happy switch" is a kind of Brain-Computer Interface (BCI, 脑机接口). It works like a bridge— it connects your brain to a computer. Some BCIs can influence people's brain activities. Some can let people control the computer with their thoughts.

Doctors at Shanghai Ruijin Hospital helped a patient called Wu Xiaotian. Wu, 31, has had depression since he was 15years old.

The doctors did a surgery on Wu. They put two long lines of electrodes(电极) inside his brain. The 16 electrodes are used to let out electricity on different parts of the brain, which can change the patient's feelings. The electrodes are connected to a small "box"—the power source(电源)—inside Wu's body.

Wu can control the"happy switch"remotely via an app on his phone. When feeling down,Wu turns on the switch and the electrodes start working. He is soon cheered up. "It feels like there is power rising from the inside of my body," Wu said.

"The hospital has tested the switch on 26 patients since 2020. Up to now , it has helped cut down a patient's sad feelings by 60 percent," said the hospital.

But is the switch safe enough? Although patients like Wu feel great using it, the implant surgery is actually a dangerous one. Also, doctors have to make sure that patients don't rely on it. Healthy people shouldn't use it, or it may be like a kind of addiction(瘾) for them.

In Beijing, along the famous Chang' an Street, a lot of bikers ride very expensive bikes. It is said that bikes are priced at between 1,000 yuan and 100,000 yuan. Bike riding becomes popular among people in some big Chinese cities.

Li Ming, who worked as a sales manager at Specialized before, said that people became interested in having a bike especially in China's big cities. He added that now many people could accept high prices for premium(高端的) bikes.

As the two Olympic Games were held in our country, the government started to pay more attention to sports. People began to realize the importance of having a healthy body. It's said that the popularity of bike riding is related(相关的) to the COVID-19 epidemic, people's higher living standards and people's awareness(意识) of the importance of a healthy lifestyle.

At the same time, more and more bike lanes(自行车道) are built in some big cities. People's need for a lot of bikes is a big chance for bike makers. Some best selling road bike s are always sold out quickly.

Teachers' Day is an important holiday in China, and it has been around for thousands of years in some ways! 

In old times, a similar holiday 1 by people on the birth of Confucius. Besides celebrating Confucius' birth, all teachers had2 day off and received dried meat as gifts. Excellent teachers3 got silver coins. 

Modern Teachers' Day in China was set up by the government in 1985. The government hoped4 more people would know the importance of teachers through celebrating this holiday. Now, people celebrate Teachers' Day5 September 10th every year. 

One of6 Teachers' Day celebrations is visiting the old school. This allows students who have graduated (毕业) to show thanks to7 old teachers. For students still in school, there are many ways 8 thanks to their teachers, such as sending cards, writing letters, or giving flowers. Many schools have class celebrations on this day as well. For example, some classes will give "Most Popular Teacher" awards. 

In China, people9 teachers to gardeners (园丁) and students to flowers. This comes from the idea that students need love and care to grow10 , just like flowers, And, of course, the most skilled gardeners grow the most beautiful flowers!
