Frightened. That’s how I felt that Monday morning when my students came into class and began asking one of their classmates to tell them what had happened at the beach yesterday.

I was frozen in _______. Being islanders surrounded by water, I teach my students that the ocean is not a _______ place, but can be very merciless (无情的) to those who make mistakes. As such, my first thoughts were for their safety. I did a quick head count. They were all in class in _______. I became less afraid and more _______ about what had happened. But I wasn’t wholly prepared for the story they did.

A three-year-old boy playing in the water near the beach had been left not _______ by his elder sister for a moment. When she turned around to find him, he had drowned (溺水). Worried family members and beachgoers _______ to help, but no one was sure what to do. One of my students was at the beach that day and had taken a CPR and first aid (急救) course that I’d taught as an after-school program seven months earlier. Remembering her _______, and with the help of a swimmer, she began providing first aid and asked others to call 911. By the time doctors arrived, the child was _______ and in his mother’s arms.

Words still fail to _______ how it feels to have been part of such an amazing event. When I asked her how it felt to have saved someone’s life, “Pretty cool, “ she said. I guess so.

As teachers, we know that through our energy and effort, children learn something useful. They become interested and try to achieve their dreams. In this way, we have the _______ to change lives.

It’s a common belief that fish can’t remember anything for longer than seven seconds. It may seem sad to think that every moment in their lives would be like seeing the world for the first time. But don’t be so quick to feel sorry for them. A new study has found that fish have much better memories than we used to think.

In the study, researchers from Mac Ewan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They took the fish out and then waited for 12 days before putting them back in the tank again. They found that after a long break the fish still went to the same place where they first got food.

In fact, scientists had been thinking for a long time that African cichlids might have a good memory. But there was no clear evidence until the latest findings. Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild. “If fish are able to remember that a certain area contains (容纳) safe food, they will be able to go back to that area without putting their lives in danger.” lead researcher Trevor Hamilton told Live Science.

So next time you are watching your pet fish from outside the tank, perhaps you should feel closer to them—they may remember who you are.

The following news is from China Daily (www. chinadaily. com) which covers different fields.

The Vaccines May Be ready Many countries are developing the vaccines for COVID-19(新型冠状病毒肺炎) by different methods. Some are even going through the final step to decide how well the vaccine works and if it’s safe. With more than 160 possible vaccines under study, experts hope that vaccine may be ready by the end of 2020.

For some students, getting better grades can seem like an impossible task sometimes. With the challenges(挑战) of school, just paying attention in class or studying hard isn’t always enough. But what if there were other ways for students to improve their grades? For parents and students who have ever wondered if this is possible, now you can rest easy. Research suggests that a person who likes doing activities can improve their grades.

Scientists think that those students who are active are not just exercising their bodies, but also exercising their brains(大脑). In turn, they can be able to improve their grades at school.

In the most recent study, researchers found that when children played for half an hour each day, they were better at organizing(组织) their schoolwork as well as doing project work and learning traditionally “difficult” subjects, such as maths.

What does this mean for children who aren’t active? Researchers think that if kids don’t get enough activities, they are going to be at a disadvantage when it comes to school performance.

In the research experiment, a group of children skipped with ropes(跳绳), played basketball and did a number of other games or exercises. Another group of children didn’t do any activities. They took part in testing both before experiment and after the experiment. Testing was mainly for maths and reading skills. Results showed that the children in the activity group did better on the tests than those who had no activity.

All work and no play will not only make Jack a dull(迟钝的) boy, but will also negatively(消极地) affect his grades in school, according to a new study published in the Journal of Pediatrics.

Parents complain(抱怨) children today are actually less active and they always worry about their grades. Dr. Belton, an expert, said, “If you’d like to see your kids do better in school, have them close their books, set down their pencils and go outside to play.”

When throwing away rubbish, do you know     36     bin it should go in? Have you ever     37     (notice) the differently-colored rubbish bins on the street?

Some of you might not be able to answer the questions. However, it’s actually quite     38     (importance) to know how to sort(分类) your rubbish. Not     39     (know) how to sort rubbish can make it     40     (hard) to save energy and protect the environment. If you don’t sort your rubbish,     41     of it will be buried(埋) together. It can take up large areas of ground that could have been used for     42     (plant) trees. Shanghai is the first city     43     (put) rubbish-sorting into practice in China. Shanghai government has asked all the people who live there to sort rubbish into four groups: wet, recyclable, harmful and dry. “Wet” rubbish is also known as “household” rubbish. It is what people produce every day     44     they eat or drink. “It is the thing you don’t want but pigs can eat”, Guangzhou Daily explained. Paper, metal, glass and other things that can be recused are recyclable rubbish. Harmful rubbish includes things like medicine, batteries and so on. Finally, any rubbish that is not wet,     45     (recycle) or harmful will go in the dry rubbish bin.

With online booksellers and e-readers becoming popular, traditional bookstores seem to be dying out. But is it true? Many traditional bookstores are now trying everything to make themselves more attractive (有吸引力的) to readers. And some of (A) them have done a great job. Online bookstores usually have larger book stocks (库存) than traditional bookstores. However, some traditional ones are clever enough to sell just one kind of book and win the hearts of a special group of people. Trends Lounge in Beijing is such a place for art lovers. The bookstore has walls of books about arts and design. You may meet popular artists there or perhaps even a happy couple that chooses to get married in the bookstore.

Some bookstores even go one step further. They themselves have become tourist places by showing the characteristics of their cities. Hong Kong has many second-floor bookstores. These bookstores are small, but their books are carefully chosen, just like the city of Hong Kong.

In order to attract customers to read books at the store, some traditional bookstores are also coming up with coffee centers in bookstores, providing free WiFi for readers, holding reading clubs for students and opening a self-service book store in the downtown area.

A great bookstore can encourage people to read in many ways. After all,you can’t replace (替换) the touch of paper, the smell of print, and the wonderful feeling of being in a bookstore. Paper books give people a very different reading experience compared with e-books.
