【推荐1】The pilot whale（座头鲸）is one of the largest sea animals in the world. Some of them can be 7 meters long and 3000 kilos heavy. There are about 4000 pilot whales in the world. Most of them live in the Pacific and the Atlantic. A few of them can be seen in Bohai and other big seas in China.
In September, a tragedy happened on the west coast of Tasmania,
Australia. As many as 380 pilot whales became stranded（搁浅）and died. It may be the largest stranding happened in Australia on record, the BBC reported.
For centuries, the whales stranding happened all over the world. Why do pilot whales do this? Scientists did a lot of studies, but they say the reason about that is often unknown. Instead, they offered some different guesses.
Some scientists say the whales catch small fish for food and get stranded because they are not noticing where they are going. Others think that the earth has a geomagnetic field（地磁场）, which makes the whales change their ways of travelling into the wrong place.
There is another guess. Pilot whales travel in large groups. “If one head whale wrongly takes the whole group far away the deep sea, the others will not leave. ” said Shery Gibney, a great scientist from New Zealand. “Some will come in and try to help, they get stranded on the beach, then more will come. ”
Pilot whales can float （漂浮）in the deep water easily although they have a very large body. If they get stranded, their heavy body can slowly kill themselves. More than 90% of all the stranded whales will die, according to the NOAA of the US.

【推荐3】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.
1. We often feel sorry for fish because they have bad memories.2. The researchers carry out the research to find out if fish can find food easily.
3. The underlined word “tank” in Paragraph 4 means a container for keeping fish.
4. A good memory can make fish safer in the wild.

【推荐1】The jackfruit (菠萝蜜) is a delicious fruit in Asia. When thinking about the fruit’s English name, you may ask, “Who is Jack? Why does he have his fruit?”
Jackfruit isn’t a person’s name at all. The fruit’s name first comes from the Indian word “Chakka Pazham”. Later, Portuguese (葡萄牙) travelers came to India and called it “Jaca”. This brings us to its English name of jackfruit, said NPR.
There is another food, however, named after a person—the sandwich. In the 1900s, playing card games late into the night became popular in Britain. John Montagu, the 4th Earl of Sandwich, started to eat pieces of cold beef between two pieces of bread. This was a late-night meal without leaving the gaming table.
There are more names named after people. Long Johns are warm trousers that keep us warm in winter. It’s said that they were named after the US boxer John L. Sullivan who liked wearing a similar kind of clothing in the games.
So, the next time you find an interesting name in the English language, why not go into its history?

【推荐2】As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success.
Scientists have found out that the radiation (辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of the radiation from the sun and other stars, which is bad for their health. The harm of the radiation won’t be discovered until their children or even grandchildren are born. Some special medicine may work a little, but no really effective (有效的) medicine has been found so far.
Space junk is also thought to be a great danger to spacemen. It’s reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space junk. An explosion (爆炸) in space in 1999 made a cloud of 300,000 fragments, each at least 4mm in size, and even a small piece of these knocked against a spaceship window and did some damage (损坏).
Scientists are watching and reporting any possible danger all the time. They are working on helpful ways to do with space junk. Although space is really dangerous, it interests everyone on the earth. In the near future, it may become possible for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should care for space and do something to help improve the space environment.

【推荐2】This year, COVID-19 broke out again in many places in China. Shanghai is one of the worst cities among them. To fight against COVID-19, Shanghai built many makeshift（临时的）hospitals in the city.
Inside a makeshift hospital, a group of 28 disinfection（消毒）robots were working busily. Each of them could work 24 hours a day without any rest.
