【推荐1】About a billion birds die from flying into buildings each year in North America. Suspicions have been that birds may regard the open areas behind glass as safe passageways. Or they may mistake the reflected trees for the real thing.

Researchers would like to reduce collisions, which requires a solid understanding about what makes a bird more or less likely to die by crashing into a building in the first place.

“There was relatively little known at a broad scale. Previous studies were at one small study site.'' Jared Elmore, a graduate student in natural resource ecology and management at Oklahoma State University. So he and his colleagues used a previously created data set of building collisions for birds at 40 sites throughout Mexico, Canada and the U.S.

The first finding was obvious: bigger buildings with more glass kill more birds. But the details were more remarkable. "We found that life history predicted collisions. Migrants(候鸟), insect-eaters and woodland-inhabiting species collided more than their counterparts(同类).”

Most migratory species travel at night, when lights near buildings can distract or disorient(使迷失方向)them. And Elmore thinks that insect-eating birds might be attracted to buildings because their insect prey(猎物)is attracted to the lights. He suspects that woodland species get tooled by the reflections of trees and bushes in the windows. The results are in the journal Conservation Biology.

By understanding which birds are more likely to collide with buildings, researchers can perhaps determine the best way to adapt buildings, or their lighting, to help prevent such accidents. And by knowing risks, along with migration timing and behavior, building managers can better predict when birds are at their greatest danger - and improve lighting strategics accordingly.

Elmore's next project will use radar to help predict bird migrations. " I think that would maybe go a long way in terms of providing information to people, to the public, to building managers, on when they can get the most benefit in terms of lights-out policies."

【推荐2】For many animals in the ocean, crabs are food. That’s a problem for crabs. How can they stay off the dinner menu? One type of crab, known as the decorator crab, has found a clever solution. It “decorates” itself. Decorator crabs use seaweed to change their appearances so that predators (捕食者) will not recognize them.

More than 100 species of decorator crabs are found all over the world. One species, commonly called the longnose spider crab, takes decorating to a whole new level. The ocean floor was covered in seaweed, but these crabs wouldn’t use just any kind they found. “They were very, very picky, and things they pick were quite uncommon.” says Dr. Stachowicz of the University California.

He noticed that longnose spider crabs would grab a piece of seaweed and take a little bite. Sometimes they would just eat the seaweed. Other times, they would reach back and attach the piece to the small hairs on their back. These crabs were choosing to decorate themselves with seaweed that has a peppery-tasting (胡椒味) chemical in it. Most fish find this chemical unappetizing. “If the crabs just decorated to look like the background, they would be giving their predators a little side salad with the main course.” says Dr. Stachowicz. But by carefully choosing the peppery seaweed, these decorator crabs look less tasty and predators avoid them.

Once a longnose spider crab has put together a good suit to protect itself, it is set for a while. The seaweed continues to grow even while it’s stuck to the crab’s back. When a crab sheds (去除) its old shell, it has to redecorate, often using seaweed from its old shell. Basically, the crab recycles.

【推荐3】Some turtles(乌龟) are famous for their medicinal(药用的) effects, which are discovered through scientific researches, while others are highly regarded as food. Nowadays, they are becoming more and more popular in pet stores. If you are thinking of getting a pet turtle, you must make sure that your turtle gets the best care.

Turtles do best when they are kept outside. Most turtles like to hibernate during the winter months. If they kept inside, they won't hibernate because they won't be able to tell what time of year it is, then they might develop liver(肝脏) problems.

If you decide to keep your pet turtles indoors, make sure you have at least a forty-gallon tank(水池) for them. At least one third of the tank needs to be placed to land.You may place some large and flat rocks in the tank, to give the turtles an area on which to sun themselves. Make sure they get at least twelve hours of sunlight every day.

Unfortunately, turtles are not pets which can be played with. They are cold-blooded pets and it takes them a long time to get used to changes in temperature. Taking the turtle out of its nice warm tank causes quite a shock to the turtles, and could damage its immune(免疫的) system. You should keep your turtle's environment as unchanging as possible, and also as clean as possible.

【推荐3】Seamus Blackley is well known as the man who came up with the idea for the Xbox game system. But Mr.Blackley was a scientist long before he worked on video games. Most scientists always want to study everything in the world, and that’s true of Mr. Blackley, too.“I had been baking when I was a child and I picked it back up 10 years ago.” he said. Now Mr. Blackley calls himself a “bread nerd”, and what really interests him is yeast (酵母).

When many people think of bread yeast, they think of something you buy at the store. But yeast is tiny living things found just about everywhere.

Though yeast is animate, it isn’t always active.When there’s not enough food ( like sugar or flour ), yeast becomes dormant (休眠的). Basically, it dries out and goes to sleep. It can stay dormant for thousands of years.

Dormant yeast can be made active again with warmth. In April, Blackley made bread with yeast that someone told him was 5,200 years old. But when he realized he had no way of knowing how old the yeast really was, he decided to colleet his own ancient yeast.

To do this, he worked with two other scientists: Richard Bowman, who studies tiny forms of life, and Serena Love, who studies and teaches about ancient Egypt. Dr. Love was able to connect the scientists with 4,500-year-old Egyptian clay pots (陶土罐) at two museums in Boston.The team successfully collected yeast from the tiny holes in the clay pots.Mr.Bowman took most of the samples (样品) to do other tests. Mr. Blackley kept one sample. He wanted to test it in his own way by making bread.

Mr. Blackley worked carefully to get the dormant yeast active again. Then he made a piece of bread using the yeast.Mr.Blackley said the taste of the bread was “unbelievable” and anyone could tell the difference. But he was still not 100% sure whether he’d baked with 4,500-year-old yeast. It’s possible that some more recent yeast got in the clay pots.

1. What sort of man is Seamus Blackley?

A．A man who’s outgoing.	B．A man who’s confident.
C．A man with wide interests.	D．A man with a warm heart.

2. What does the underlined word “animate” in Paragraph 3 mean?

A．Alive.

B．Popular.

C．Cheap.

D．Useful.

3. Why did Mr. Blackley work with Serena Love?

A．To get a sample of yeast.	B．To learn tiny forms of life.
C．To make the yeast active.	D．To make clay pots.

4. What made Mr. Blackley doubt the age of the yeast?

A．He found the taste of the bread was wrong.

B．He doubted the clay pots were not that old.

C．He had done a terrible job in activating the yeast.

D．He thought there might be recent yeast in the clay pots.

【推荐1】According to University World News, there are around 200 million students who are affected due to the COVID-19 pandemic. However, great minds did not let the hours go for nothing. As online education was already familiar, chances of establishing the mainstream policy of conducting classes through online increased greatly.

A huge response from all over the world is seen. Many universities and schools started conducting their classes through Ding Talk TV, CCTalk or other conferencing portals (入口). It is known that this procedure will not last if situation becomes stable again as what is now going on is only a “Better than nothing” option, but the appeal and impact of “E-Learning” will definitely remain.

Undoubtedly the online education will make a huge impact on the lifestyle and time consumption of the people as life will become even faster and more comfortable than now. Also the transportation problem of the country will be solved as students will be able to conduct the classes from home. More precisely, wastage of time will be removed completely, which would help the students to become more concentrated and hardworking. Another major problem is the accommodation problem which will be settled completely as anybody can access the classes sitting in their own home.

However this E-Learning method may result in some possible problems in future. Even for the time being, though the credit (学分) hours are counted and the students are graded on the basis of online exams, some courses and subjects should be left out for later to be conducted physically. For example, subjects which do not require practical experiments or are computer related, such as literature, history, law, computer science, mathematics, etc. are completely okay to be conducted in both the classroom and E-Learning. Whereas, chemistry, biology, agricultural science, all the medical departments, etc. or in short, whatever the course is, if that requires practical application, practice and fieldwork, shouldn’t be conducted in the virtual class.

Therefore, all the courses which require lab work or practical application, should be separated and designed as a “Lab Year” and conducted those classes physically when situation becomes normal. Even some of the theoretical courses, such as law, journalism, should have a few courses conducted later for the students’ own benefit in future. In other words, there should be a balanced way of handling the situation.

1. According to the passage, E-Learning is very likely to ________.

A．settle the transportation problem	B．help students find a house to live in
C．cause students to waste more time	D．make people’s life less comfortable

2. Which of the following might be the possible problem of online education?

A．Students can’t be graded fairly based on online exams.

B．Some courses requiring practice can’t be conducted physically.

C．Computer Science and history have to be conducted online.

D．Some subjects should be left out for later to be conducted online.

3. What can be inferred from the passage?

A．Online education will replace the traditional one.

B．The effects of “E-Learning” exist for the time being.

C．The theoretical courses needn’t be conducted physically.

D．Traditional Education will still have a place in the future.

4. What might be the best title of the passage?

A．Online Education: Impact and Practice

B．Online Education: Benefits and Problems

C．Online Education: Problems and Solutions

【推荐2】Egypt ranks among the world’ s oldest civilizations and is famous for its ancient pyramids.     1     For thousands of years, this world wonder has wowed visitors and brought in countless money for the locals. However, thanks to Covid-19, there is a historic clean up at the pyramids.

The virus killed off Egypt ‘s tourism and with it, the livelihoods of millions. Like Ashraf - - unable to feed his family, he kept his favourite camel, but had to sell two others. “It has been tough on everyone,” he says. “I have no money.     2    ”.

The ancient attractions are now reopening, but they’ re empty except for a few local visitors. It’ s a blow after tourism had just recovered from years of disorder.

Tour guide Shahenda loves taking tourists around her country. Since the pandemic, she’s lost a thousand holiday bookings.     3     She said, “We had to cancel flights, hotels, and many other arrangements. Everyone is badly affected. We have lost our jobs, and then you will.”

According to Khalid Al-Anany, tourism minister, Egypt lost around one billion dollars per month and it’s expected that the country will still lose a lot of money during the next coming weeks and months.

    4     The tourism minister is on a mission to bring back business and bring the economy back to life, highlighting new hygiene and safety rules and showing how foreigners can now fly in to some beach resorts.

    5     Hopefully the lasting charm of pyramids will speed it up. For Egypt, what could be more proper these days than a golden face mask?

A．Restoring tourism will take time.

B．It’s time that the government took action.

C．A camel’s food alone costs six dollars a day.

D．For now, she’ s only sightseeing with her husband.

E．Tourists have to overcome lots of difficulties before reaching the pyramids.

F．There is no question it is a place loved by tourists all across the globe.

G．Thanks to the progression in technology, you can easily apply for Egypt visa in no time.

【推荐3】There have been assumptions about possible detrimental long-term consequences of school closures on young children and adolescents, but now a new study published in the journal Scientific Reports provides convincing evidence that the mental health of school children was damaged by school closures during the pandemic.

The study surveyed 907 adolescents and their parents in Germany between May and June of 2020. Depression and psychosomatic symptoms were evaluated, in addition to other aspects of mental health. Telephone call volume to German youth crisis helplines was also analyzed. Both sets of data found higher depression and psychosomatic symptoms, particularly among boys, younger children, and adolescents, especially those living in homes with limited space. The research suggests that increased pressure on families forced to adapt to new work, school, and family life situations during the pandemic school closures promoted the increase in mental health problems in school children.

Not all children suffered the effects equally. Young children suffered the most from the pressure caused by school closures. Boys coped much worse with school closures than girls. The effects were strongest in school-aged children living in homes that had limited living space. That factor supports the conclusion that family living stresses promoted the decline in mental health.

Disrupting daily routine and social interactions do damage to the mental health of school children, the researchers conclude. Given the obvious importance of wholesome daily routine in family life and the value of health y social interactions in nurturing the well-being of children, it is not surprising that kids’ mental health suffered when their schools were closed for long periods and their family life was greatly changed.

COVID-19 is not the first, nor will it be the last serious infectious disease sweeping the globe. These new findings will be valuable in deciding how best to manage such outbreaks in the future.
