Rodney Smith is a man with a task.The Bermuda native is in the midst of a trip that will take him to every state in the nation, mowing lawns（修理草坪）.

Five years ago, Smith came across a senior man mowing his lawn and stopped to help.“When I came across the elderly man, my life changed,” he sai

D.After that, Smith went on to create the Raising Men Lawn Care Service (RMLCS) to mow lawns for the elderly, disabled, single moms and former soldiers free of charge.As part of providing free yard work, the organization teaches children about serving their communities and lawn mower safety.

A key component of RMLCS is its 50-yard challenge, which sets a goal for children nationwide to mow 50 lawns for free in their community.When a kid signs up for the challenge, the group sends them a white shirt with the Raising Men logo（标识），shades and ear protection.The participants receive a different colored shirt after every 10th lawn they mow.When they have completed the task for 50 yards, they receive a special visit from Smith or someone with RMLCS.They give the volunteer a new lawnmower, free of charge, and cut other lawns with them.

Since this challenge started in 2016, 12 kids have already completed the challenge.And both boys and girls are part of it.At present they have 130 kids nationwide taking part in this challenge, including7 inBermuda and the U.K.and one in Canada.So it’s spreading worldwide.Even the Queen of England took notice — the governor of Bermuda presented Smith with an award late last year on behalf of her.

It was also last year that Smith came up with the 50 States 50 Lawns campaign.Now, in 2020，he’s on the road again.

Adolescent chimpanzees adopt their younger siblings (兄弟姐妹) if their mothers die.The older siblings keep a close watch on the youngsters and give them lots of comforting hugs.

The finding adds to the evidence that chimpanzees can understand when others are suffering and can, to some extent, help them.Similarly, a second study has shown that chimpanzees have a strong emotional response when they see that another chimp or a familiar human is injureD.

Rachna Reddy and John Mitani at the University of Michigan were tracking a group of about 200 chimps in Kibale National Park, Uganda, when a deadly disease struck the animals between December 2016 and February 2017.Twenty-five chimps died and 13 lost their mothers.Reddy and Mitani kept a close watch on four pairs of young chimpanzee siblings, where the older of the two effectively adopted the younger.The older chimps were 10-17 years old while the younger siblings were 6 to 7 years ol

D.The pairs spent much more time together after their mothers' deaths than they did before.They also comforted each other."It was like they were both seeking physical contact all the time," says Reddy."The behavior makes evolutionary sense, because by helping their siblings, the older chimps are acting in the interest of their own genes." We can't be sure what is going through their minds, but Reddy says the younger siblings were clearly scared and upset and the older siblings seemed to take the situation seriously."I am hesitant to use a word like 'responsibility'," says Reddy, but she says they were responding to their siblings' suffering.

In line with this, chimps react when one of their members is injured: they may inspect or help deal with a wound, for instance.Yutaro Sato at Kyoto University in Japan and his colleagues have now found that chimps respond on an emotional level to seeing an injury.They showed six chimps a human with whom they were familiar, and who had a serious wounD.The cameras showed a temperature drop inside the chimps' noses, which is known to have links with a strong negative emotion.

4.Why did the older chimpanzees adopt the younger siblings?

A.Because they enjoyed having playmates.

B.Because they observed the law of jungle.

C.Because they were taught to take responsibility.

D.Because they understood their siblings' suffering.

5.What is the purpose of paragraph 3?

A.To show how they conducted the research.

B.To make an analysis of the findings.

C.To compare the two researches.

D.To describe a moving story in the research.

6.What does the underlined word "this" refer to?

A.Chimps' unwillingness to help.

B.Chimps' minds full of sadness.

C.Chimps' reaction to their siblings' suffering.

D.The decrease of chimps' nose temperature.

7.Which is the best title for the text?

A.Chimps really do care

B.The mystery of chimps

C.Chimps: to be or not to be

D.The power of evolution

Wood has many great characteristics that make it the perfect building material.It is cheap，durable(耐用的),easily available，and most importantly，environmentally sustainable.The one thing it is not, is transparent(透明的).Now thanks to a team of scientists at Stockholm’s KTH Royal Institute of Technology，the material may even be able to add that feature to its already impressive list.

Lead researcher Dr.Lars Berglund said he was inspired to create the transparent wood after learning how Japanese researchers had developed a see-through paper for use in flexible display screens for electronic devices.The team began by pulling out the wood's lignin(木质素).The lignin-free wood was then dipped into a polymer(聚合物)and baked at a temperature of 158F for four hours.The result was a hybrid product that was not only stronger and lighter than the original wood but also，almost transparent.The researchers were able to adjust the level of transparency by varying the amount of the polymer injected and also by changing the thickness of the wooD.

While scientists have previously created a see-through wood for small-scale applications like computer chips, he transparent wood is the first one being considered for large scale applications.The researchers, who revealed their findings in Biomacromolecules on April 11, picture using the transparent wood in buildings to allow for more natural light, or to create windows that let in the desired amount of light without sacrificing privacy.

Wood that allows light to pass through could lead to a brighter future for homes and buildings.Berglund also thinks the wood could play a significant role in the design of solar panels.The semi-transparent material would be able to keep light longer and give it more time to interact with the conductor, thus resulting in better solar efficiency.Additionally, substituting the currently used glass with this new product would help solar energy manufacturers improve their carbon footprint and lower the cost.They are now experimenting with ways to scale up the manufacturing process so that the transparent material is cost-effective to make and easy to use.

8.What does the underlined part “that feature” in Paragraph 1 refer to?

A.Cheapness.           

B.Durability.            

C.Sustainability.       

D.Transparency.

9.Which of the following is not the process in which the transparent wood is made?

A.Dip the wood into a polymer.

B.Reduce the amount of the polymer.

C.Make the wood lignin-free.

D.Bake the wood for some time.

10.Which of the following is true according to the text?

A.Berglund got the idea of transparent wood while making paper.

B.Varying the amount of the polymer changes the wood's hardness.

C.The cost of making the transparent wood still needs to be cut down.

D.The transparent wood would be used only for homes and buildings.

11.What is the last paragraph mainly about？

A.The bright future of the transparent wooD.

B.The wood's role in the design of solar panels.

C.The disadvantages of the currently used glass.

D.Solar energy manufacturers' carbon footprint.

D

Dolphins, African gray parrots and some other animals understand the idea of “zero,” but researchers were surprised to find that honeybees also comprehend this abstract concept, considering the insects’ tiny brains, according to a new study.Honeybees have fewer than one million neurons (神经元), compared with the 86 billion neurons in humans—and yet, they grasp a concept that humans, by some measures, don’t start to understand before preschool.

The researchers set up two cards, each of which had a set of symbols on them, like triangles or circles.Then, they trained a group of the bees to fly to the card with the lower number of symbols.The bees quickly learned what the humans wanted them to do to get their delicious, sweet rewards.The trained bees were then shown a card that was empty and one that had symbols on it.There is no need for the bees to be trained to fly more often to the empty card—thus showing that they understood that “zero” was a number less than the others.

Although they flew more often to an empty card than to one that had one symbol on it, it became easier for them to distinguish when the symbols on the card increased in number.For example, they more often flew to the zero when the other card had four symbols than when it had one.

Perhaps these findings will explain the brain mechanism (机制) behind what allows us to understand the concept of “nothing,” Adrian Dyer, a researcher saiD.This understanding, in turn, could help in the development of artificial intelligence (AI) that also understands this concept.“If bees can understand ‘zero’ with a brain of less than a million neurons, it suggests there are simple, efficient ways to teach AI new tricks,” Dyer said in the statement.

12.What is a surprising finding for the researchers?

A.Many animals also comprehend the meaning of “zero”.

B.The number of neurons of honeybees is much smaller.

C.Honeybees can understand “zero” with their tiny brains.

D.Humans fail to recognize abstract ideas before preschool.

13.What can the bees do without further training?

A.Fly directly to the card with more symbols on it.

B.Fly less often to the card with fewer symbols on it.

C.Fly quite slowly to the card without anything on it.

D.Fly more often to the card without any symbol on it.

14.What does Adrian Dyer say about these findings?

A.They offer inspiration to the development of technology.

B.They enable people to understand more abstract concepts.

C.They suggest ways to teach humans some complex tricks.

D.They allow people to set a new type of brain mechanism.

15.What is the main idea of the text?

A.Honeybees know about the concept of “zero”.

B.Honeybees can understand much as humans do.

C.Honeybees will help to improve AI in the future.

D.Honeybees can be trained to comprehend “zero”.
