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.

Hong Kong is surrounded(环绕着的) by mountains and seas. It lies in southern China, and is China's"South Gate"to the world. In the old days, HongKong was only a small fishing village, but now Hong Kong has become an important trading center and shipping center in Asia and the Pacific. Since HongKong's return to China in 1997, the rule of law system has been perfected.

Hong Kong is made up of three large parts and nearby islands. There are few flat areas in Hong Kong, and only a small part of the coastal area is low,surrounded by hills. Because Hong Kong is one of the most densely(稠密地) populated areas in the world, dozens of high-rise buildings are built on hillsides.

Hong Kong's tourism industry is highly developed. There are all kinds of goods from all over the world, and the prices are very low, so Hong Kong is a good place for buyers. It is also a place where Chinese and Western cultures mix. Food from all over the world is brought together to make Hong Kong a"FoodCapital". Every year,a large number of tourists from all over the world come to visit.

Dear Amy,

You asked me about the gardens in Shenzhen last letter. You know that Shenzhen has built a lot of gardens.

Do you want to come here and have a look? I hope to hear from you soon.

Yours truly,

Li Hua

Scientists say they recently invented the world's tiniest remote—controlled robots. The robots are small enough to sit on the side of a coin. They don't have any power of their own，and they can be controlled from a distance by using lasers（激光器）. The scientists say one day robots like these may be able to work in areas too small for tools. The robots don't move very quickly. But because of their tiny size，they're also not too slow. It takes the robots about 20 seconds to cover 1 centimeter. 

Right now the robots aren't all that useful. All they can do is to move，and they need to be in a place where lasers can shine on them to do that. But the scientists say these robots are an important step toward inventing more helpful tiny robots. 

The researchers say that one day tiny robots like these might be able to work in very small spaces. It's possible that they could build very tiny machines，or perhaps even travel inside the human body to help do with medical problems. 

Using similar building methods，the scientists made a number of different robots，including ones that looked like small insects. John Rodgers，says that their methods allow them to "build walking robots with almost any sizes or 3 D shapes. "

There is a competition for photographers (摄影师) of wildlife in the Natural History Museum in London every year. This year, the competition had about 50,000 photos.These photos come from different parts of the world. They take us underwater, deep into the woods, and high above cities. All of them show different kinds of life on earth.

In the end, the great prize went to Laurent Ballesta. The French photographer won the prize for his photo of a horseshoe crab. In the photo, the horseshoe crab looks for food in the sea. Three little fish follow it closely. They may hope to eat what the horseshoe crab misses.

Horseshoe crabs are known as "living fossils (化石)". They have lived for at least 445 million years and stayed almost unchanged. They're now in great danger, however. What happened to them? In the 1960s, scientists found something surprising. The blue blood of horseshoe crabs can be used for scientific study. As a result, hundreds of thousands of them are caught each year.

For a long time, Ballesta took photos of horseshoe crabs in the sea. His winning photo took the judges (评委) by surprise. "To see a horseshoe crab so alive and well, in such a beautiful way, was fantastic," said one of them.

Read the passage and answer the following questions.

On weekends, the school is often quiet. But at Furong School in Sangzhi of Hunan Province, students take part in fun activities, such as playing soccer, {#blank#}1{#/blank#} and singing under the care of their teachers. 

Most students at the school are left- behind children. Their parents work far from home and they have{#blank#}2{#/blank#} to do on weekends. The school sets up some clubs so that the students can learn and {#blank#}3{#/blank#} during weekends. 

Huang Ying is in the Table Tennis Club. "I often watch table tennis {#blank#}4{#/blank#} on TV. I think playing table tennis is one of the best ways of staying {#blank#}5{#/blank#}. I play table tennis after school every day and I am really good at it now. " Huang says.
