It’s a popular belief that fish can’t remember anything for longer than seven seconds.

It may seem sad to think that they don’t remember what they’ve eaten or where they’ve been, and they don’t know you or any of their friends—every moment in their life would be like seeing the world for the first time.

But don’t be so quick to feel sorry for them. A recent study has found that fish have much better memories than we used to think. In fact, certain kinds of fish can even remember events from as long as 12 days ago, BBC reported.

In the study, researchers from MacEwan University in Canada trained a kind of fish called African cichlids (丽鱼科鱼) to go to a certain area of their tank (鱼缸) to get food. They then waited for 12 days before putting them back in the tank again.

This suggested that they could remember their past experiences. Researchers used computer software to watch the fish’s movements. They found that after such 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. An earlier study showed that they behaved aggressively in front of certain fish, perhaps because they remembered their past fights. But until the latest findings, there was no clear evidence (证据).

Just as a good memory can make our life easier, it also plays an important part when a fish is trying to live on in the wild.

“If fish are able to remember that a certain area has 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.

1. A popular belief is mentioned at the beginning of the article to ________.

A．explain why fish have a bad memory

B．guide readers to the topic of the article

C．show fish can remember their neighbors

D．introduce how fish improve their memory

2. According to the study at MacEwan University, fish ________.

A．remember what they’ve eaten	B．like staying in the same tank
C．are smarter than we thought	D．can learn something from man

3. The underlined word “aggressively” in Paragraph 6 might mean ________ in Chinese.

A．友好地

B．得体地

C．攻击性地

D．礼貌地

4. What Trevor Hamilton said in the last paragraph tells us it’s ________.

A．important for fish to have a good memory

B．easy for fish to find a place with safe food

C．necessary for fish to remember their home

D．dangerous for fish to fight for their friends

【推荐1】Have you ever had trouble sleeping in a new place?

Lots of people do. And now researchers from Brown University in Rhode Island think they know why. They found that one-half of the brain “remains more awake” than the other half when people are trying to sleep in a new place.

This appears a case of the brain keeping people ready for trouble in a new place, the researchers said.

The sleep findings were reported in Current Biology by Brown University. In their report, the researchers said many people report they have a harder time sleeping the first night at a hotel or other places outside their home. They call it “first-night influence”. “In Japan they say, ‘If you change your pillow, you can’t sleep,’” said Yuka Sasaki, one of the report’s writers, “You don’t sleep very well in a new place. We all know about it.”

The researchers measured brain waves(测量脑波) for 35 volunteers over two nights in a laboratory. The two nights were a week apart. They found during the first night the left half of the brain was more active than the right half. This was during the first deep-sleep period, the researchers said.

Sasaki said a lot of questions remain.

Researchers did not keep measuring brain waves all night long. So, they don’t know if the left half keeps “watch” all night. Or whether it “works in shifts” with the right half later in the night. They also don’t know why the brain activity, at least during the first period of deep sleep, is always on the left half.

For some, this research may be calming. It is good to know that our brain is “looking out for us” in a new place. But it may not help with sleep. That brain activity, at least according to this new research, makes it harder to get the sleep people need to wake up well rested in the morning.

1. What did the research find during the first deep-sleep period?

A．They found the brain wave remained the same.

B．They found the brain activity helped with sleep.

C．They found the right half of the brain kept “watch”.

D．They found the left half of the brain was more active.

2. Which of the following is one of the questions that remain?

A．Whether the new bed keeps you from sleeping.

B．How you have trouble sleeping in a new place.

C．Why the brain activity is always on the left half.

D．What people can do when they can’t sleep well.

3. The underlined word “calming” has the closest meaning to ______.

A．pleasing

B．different

C．serious

D．strange

4. What does the underlined word “it” in Paragraph 7 refer to?

A．The brain wave.

B．The brain activity.

C．The whole brain.

D．The left half of the brain.

【推荐2】COVID-19 has made people think harder about their relationship with nature. It has also raised questions about city lifestyles. The sharing economy, working in open offices, living in crowded apartment and the food industry's use of reusable products have made the perfect storm for a pandemic（大流行）.

Although the sharing economy might be good—it's cheaper to rent than to own—sharing spaces and objects are great ways to spread the virus. How does one do "social distancing" when they are expected to share cars, bikes and even the same offices?

The trend of using open offices, which can save space, is working against. In this type of office, workers don't have their own desk—everything is shared. Sometimes, computers and chairs are also shared, which is not hygienic（卫生的）. Luckily, more workers are working from home during the pandemics but that won't last forever.

Reusability（循环利用）is a common practice in the restaurant industry. Reusable cups and chopsticks are often used. Unluckily, reusable products increased the chance of spreading disease. For example, Starbucks recently stopped refilling customers' reusable cups in order to stop the spread of the virus.

People like to be social. But the virus has made this more dangerous. We have to be careful about how we interact with others for now. Perhaps we need to rethink about our lifestyles to reduce the spread of future pandemics.

1. According to the author, the strong point of the sharing economy is that ________.

A．it lasts longer	B．it costs less
C．it's popular	D．it's hygienic

2. Paragraph 3 is mainly about ________.

A．how working at home won't last long

B．how shared offices can save space

C．the hygienic problems of open offices

D．the sharing economy trend

3. According to the author, restaurants can spread the virus easily because ________.

A．everything is shared in many restaurants

B．they use too much disposable tableware

C．many restaurants have poor hygiene

D．cups and chopsticks are often reused

4. What does the word "interact" mean in the last paragraph?

A．play

B．exchange

C．fight

D．communicate

5. The author probably agrees that ________.

A．we need to change some of our lifestyles

B．the sharing economy won't last forever

C．no one can stay out of the sharing economy

D．we shouldn't stay away from shared products

【推荐2】There are many wetlands (湿地) in China and some of them have become the world’s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home for many different kinds of birds and animals. The world’s largest Deer Nature Reserve (自然保护区) is in them. More than 700 deer live freely there. There are not many red-crowned cranes in the world, but every winter you can see some in the Redcrowned Cranes Nature Reserve in the Yellow Sea Wetlands.

The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine, too. They are really good places for wildlife (野生生物). Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.

Luckily, more and more people are beginning to realize the importance of wetlands and wildlife. Every year, on February 2nd, many activities are held to tell people more about wetlands.

【推荐1】Our Needs

People in different places have different habits, but their needs are similar. Needs are things we must have to live. Our bodies need food and water. We also need air. We need a place to live to keep us away from danger. We need clothes to keep us warm. If we do not have these things, we cannot survive.

Needs may be a little different for people who live in different areas. If you live where it is cold, you may need special clothes to keep you warm. If you live in hot places, you may need more water and fewer clothes.

Farmers produce food that people eat. In the past, they planted seeds and pick plants by hand. Now they have machines help them do this work.

Our Wants

Wants are things people eager to have but do not need to live. Suppose you hope to get a basketball for your birthday. A basketball is a want because you can live without it.

Sometimes we may want something so much that it feels like a need. We have to make choices. For example, if you need a new coat for winter, you might not be able to get the basketball you want. We must choose what we need instead of what we want.

Sometimes we must make choices between things we want. Suppose you want to go to a birthday party for your uncle. But a friend asks you to go to a movie. The movie is at the same time as the party. If you choose to go to the party, then what will you have to give up? What will you have to give up if you go to the movie?

Jiaguwen, over 3,000 years old, is the earliest writing form of Chinese characters. Recently, it comes alive on the Chinese Internet and becomes popular as a new online language among the young people, thanks to a person who made them closer to people’s life.

Chen Nan, who creates Jiaguwen memes(表情包), is happy to know that Chinese netizens like his works. As a graduate of the Academy of Arts and Design of Tsinghua University, Chen has been studying Chinese characters’ design (设计) for 19 years. In 2016, the ancient typeface was included into the font library (字体库) under his efforts to let the ancient words walk into people’s life. Now the library has 3,500 characters, but Chen’s research on the project still continues, as he plans to increase characters to 7,000. In the future, he will put the ancient characters into education and the development of games and apps.

He has been working to make Jiaguwen into emojis (表情符号). For example, the character for “zui” which means “drunk” in English, was created to look like a sturnbling(蹒跚的) figure. Such vivid figures have been well accepted by WeChat users. Chen has also combined (结合) the ancient Chinese characters with cartoon figures. A cartoon video about Jiaguwen he designed was watched 31 million times and shared 140,000 times.

“The ancient characters are not as cool and far away from us as most people think. In fact, they are cute and funny, and they can totally serve people's needs for online expression, "said Chen Nan.

“At present, most people think Jiaguwen is hard to understand and don’t realize the great historic value(历史价值) of it. Through using Jiaguwen memes, I truly hope that more people can develop an interest in the ancient characters and use them in their daily lives.” Chen said.

“I never imagined that I could use Jiaguwen to communicate with my friends. I thought I could only see them in my textbooks and only a few researchers could understand them. Also, these memes look so creative and cute.” said a Sina Weibo user.

1. Which of the following about Chen Nan is TRUE according to the passage?

A．He used to study at the Academy of Arts and Design at Beijing University.

B．The cartoon video about Jiaguwen he designed was a success.

C．He plans to put the ancient characters into business use.

What would she get? Perhaps a new sweater. Emm, blue is such a pretty color. Or a book, a travel book, with pictures, or a little clock, with clear black numbers...

"Just post ? No parcel (包裹), Johnnie?" Her heart beat fast.

She tore the envelope open. It was a card with a message under the printed Happy Birthday—Buy yourself something nice with the check, Myra.
