A study conducted by the University of Leeds in the United Kingdom suggest that watching cute animals may lead to a reduction in stress and anxiety.

The study examined how watching images and videos of cute animals for 30 minutes affects blood pressure, heart rate(心率) and anxiety. In December 2019, 19 people, including 15 students, joined in the study.

"There were some kittens, there was puppies, there were baby gorillas, there were quokkas —cute creatures found in Western Australia, are often referred to as 'the world's most cheerful animals'." Dr. Andrea Utley, a professor at the University of Leeds told CNN. The study was timed during winter exams, a time when stress is at an especially high level for students, according to Utley.

 The study recorded that the average blood pressure dropped from 136/88 to 115/71, which the study pointed out is "within ideal blood pressure range." Average(平均的) heart rates were lowered to 67.4 bpm, a reduction of 6.5%. Anxiety rates also went down by 35%.

"I was quite pleasantly surprised that during the session, every single measure for every single participant dropped some — heart rate reduced, blood pressure reduced," Utley said. "When they left, they filled the questionnaire(调查问卷) in again and showed that they were feeling less worried."

When questioning the participants, the study found that most preferred video clips over still images, particularly of animals interacting with humans.

Do you think English is difficult? If so, you are not the only one. Many students feel it difficult to remember new words when they begin to study English. Now Ms. Manson, an English teacher, will give you some advice.

⑴Do not waste time in learning a list of English words. It is the hardest way to remember English words. How do you learn to speak Chinese? You did it by listening carefully to the people talking to each other. You can find radio programs, TV programs and records, and listen to them carefully. The best way to learn all new words is through ears. As you listen to more and more dialogues, you will learn how English is pronounced in phrases and sentences. Of course, it is not enough to learn new words. You must learn how words are put together, and why some words in English are emphasized(重读).

⑵Some people have found that they can learn the names of everyday objects such as boxes, bottles, cups and desks in the following way. They write the names of objects on paper and put the paper on them, then say the words. Try this and see if this way works for you. If it does not, then go on to practice your dialogues.

What is stress? {#blank#}1{#/blank#} It can make you feel bad and you might even have a stomachache or a headache.

 Lots of things can cause stress in a teenager's life. {#blank#}2{#/blank#} Good stress often comes when your teachers ask you to answer questions in class or when you have to give a report. {#blank#}3{#/blank#} .

 Bad stress can only make you worried and nervous. For example, you don't want to eat anything before a singing competition, or you can't sleep well before an exam. Such kind of stress isn't going to help you. {#blank#}4{#/blank#}

 Once you find you' re feeling stressed, you can try talking about your problems with an adult you trust, like a parent or a teacher.

 The best way to fight stress is to have a balanced (保持平衡的) life. Make sure you keep in mind: Sleep, Excrcise, Rest and Food, If you get enough sleep and eat well, and if you exercise and leave time for fun, {#blank#}5{#/blank#}
 

Chinese dumplings are one of the traditional foods in China. They look like ancient Chinese gold ingots(锭), which mean"rich". Chinese dumplings were first invented(发明) by Zhang Zhongjing in the Han Dynasty. He first used them for medical purposes(目的). Zhang used dumplings with mutton(羊肉) for the patients'ear chilblain. 

As time went by, dumplings became popular in the north of China, and now making dumplings on New Year's Eve has become a Chinese tradition. On New Year's Eve, family members get together to make dumplings. They may put a coin(硬币) in one of the dumplings. If someone eats the coin, he or she will have the best luck in the coming new year. Chinese dumplings are also popular in other Chinese holidays or festivals. 

In the past, people couldn't often eat dumplings because they were very poor. But now Chinese people are richer and richer, so we can eat dumplings at any time. 

Almost everyone in China likes dumplings. There are many kinds of fillings in dumplings, such as dumplings with meat and vegetables, and some with sugar, eggs and seafood. I like dumplings with vegetables and pork better than any other kind, especially eating them with vinegar. 

Making dumplings is a teamwork. People usually make dumplings at home. If you have no time to make dumplings, you can buy them from any supermarket. But on Chinese lunar New Year's Eve, making dumplings with family members means happiness and reunion. And now many foreigners also like Chinese dumplings. They eat dumplings and even learn to make dumplings. 

I hope dumplings will be loved by people all over the world.
