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 like shopping at night? If so, please come and have a look! 

Most cities and towns in China1 night markets. They take place on the same street every day, whether2 a warm or cold night. In the3 , these streets are quiet, but at night4 become crowded and lively. The sellers often get there at three or four o' clock in the5 . By 6: 00pm, the streets are like rivers of people. 

Night markets are interesting places to go6 . You can buy clothes, shoes and7 other things. You can just walk around the market or compare the price and choose8 you want. If you think the9 is too high, you can bargain(讨价还价)with the seller. You can also buy lots of delicious10 and drinks. When you are a little hungry, you can buy a snack(小吃). If you are really hungry, you can11 for a meal. Smelly(有臭味的) tofu smells bad12 tastes good. It is great to enjoy your snack, isn't it? 

There are also13 to play. In some games, you can win a prize if you are14 enough. But the best thing is that the things at night markets are cheap. You don't need a lot of15 to have a good time. 

As the weather gets warmer，there are few things that are better to do than travel．But traveling might not be that fun for everyone，especially for those who have motion sickness（晕动症）．

Motion sickness is also called travel sickness．It is a common experience for many people．Depending on how you travel，it can be called carsickness or seasickness．People with motion sickness feel very uncomfortable while they are in motion．They feel sick and dizzy，like the room around them won't stop spinning．

It is generally believed that motion sickness happens when your senses become confused （困惑的）with each other，Scientific American reported．

We use different parts of our body to sense movement．Our eyes tell us if we are moving．The inner ears （内耳） contain a special liquid that helps us sense our direction and balance．Our muscles react to movement．

When you move around，these body parts work well together．But when you are in a car or an airplane，they get confused．Your inner ear signals that you're moving．This mismatch gives us motion sickness．

But some people are less sensitive to motion sickness．This may be because they have certain genes （基因） that prevent mismatching senses，Bethann Hromatka，told the Atlantic．

Although there are many ways to deal with motion sickness，scientists believe that the key is to simply try to adapt to it．For example，some astronauts do special exercises that give them mild motion sickness．After a week or two，the astronauts become used to it and don't feel uncomfortable anymore，a NASA flight doctor，told the BBC．

Reading for pleasure (消遣) is the easiest way to become a better reader in English. It is also the most important way.

Some students say they don't want to read for pleasure. They say they want to use their time to learn the rules of the language and new words. They say that pleasure reading is too busy.

Many experts (专家) say that pleasure reading is very important for learning English. Dr. Stephen Krashen, a famous expert on learning languages, says that pleasure reading helps you learn many important things about English. Students learn more grammar and more words when they read for pleasure. They also learn more about good writing.

Dr. Krashen tells us that pleasure reading helps each student in a different way. Each student needs to learn something different. Pleasure reading makes it possible for each student to learn what he or she needs.

Reading for pleasure is not the same as studying. When you read for pleasure, you choose your own books, and you don't have to remember everything. There are no tests on your pleasure reading books. Pleasure reading will help you：

•learn how English speakers use English

•read faster in English 

•find examples of good writing in English

•learn new words 

•learn about the culture of English speakers
