The 3D-printing industry is accelerating its efforts to help fight the new coronavirus and the disease it causes, COVID-19.
On Tuesday, HP announced it’s working with those who bought its 3D printers to make medical face shields, hands-free door openers and an adjuster for face masks for medical staff who often must wear them for hours. It’s also testing “hospital-grade” face masks meeting the higher-end FFP3 (过滤式面罩) standard and parts for simple emergency ventilators (呼吸机) and it’s looking into nasal swabs to test for COVID-19 infection. HP also is offering free downloads of its 3D-printed medical equipment designs.
Carbon, whose 3D printers are used to make everything from bicycle seats to teeth straighteners, said it plans to send face shield designs to its network of customers who’ve bought its 3D printers. Carbon co-founder and Executive Chairman Joseph DeSimone said on Monday the company expects to send the designs by early Tuesday.
3D-printcr makers typically sell their products to others that actually do the 3D printing. One such customer, Ford, said Tuesday that it’s made 1,000 face shields and shipped them to Michigan hospitals, with plans to make 100,000 face shields a week. It is also working with 3M and General Electric on respirator masks and ventilator designs.
The effort is one of several to apply 3D-printing technology to the fight against coronavirus. 3D printing isn’t as fast at churning out products as conventional mass production methods. But 3D printers are flexible and able to make many different parts anywhere there’s a printer and raw materials like the plastic resins Carbon printers use.
Some 3D-printing efforts have focused on ventilators, which expected to be in short supply with a surge of COVID-19 patients suffering from respiratory (呼吸器官) problems. Also in short supply arc N95 masks that can be useful in reducing the likelihood a wearer will spread COVID-19 to others.
Carbon’s DeSimone is cautious about the enthusiasm, though, saying that regulatory approval is important and that 3D-printcr enthusiasts shouldn’t be making components not intended for close human contact that might release unhealthy gases.

In what was described as a potential terrorist attack, a knife-wielding man killed two people and wounded five others on Saturday morning in a town in southern France with only a few shops open under a national lockdown to prevent the coronavirus pandemic (新冠肺炎).
The attacks took place about 11 a.m. local time outside a bakery and other shops. Witnesses said that the suspect yelled, “Allahu akbar!" as he lunged at his victims, according to France Bleu. The assailant (行凶者)randomly attacked bystanders on the street, first cutting the throat of a man in his 40s in front of his companion and his son, in the center of Romans-sur-Isere, just south of Lyon, according to the French authorities and news media.
He then attacked two workers and a customer inside a tobacco store before heading to a butcher’s shop. The suspect, a 33-ycar-old man of Sudanese origin, was arrested by the police as he was "found on his knees on the sidewalk while praying in Arabic," said the country’s antiterrorism prosecutor’s office, which is handling the investigation into the attack. At the man’s home, investigators found religious writings in which the author complained of living in a "country of infidels (没有信仰的)the prosecutors said in a statement.
The suspect—who the French news media said was an asylum-seeker (避难者)from Sudan—was not immediately identified by name. President Emmanuel Macron vowed that "light would be shed on this odious (可 憎的)act which casts a shadow on our country, which has already been severely tested in recent weeks. "

A recent study conducted by researchers from Canada's Wilfrid Laurier University found that the snakes actively seek out socialization with their peers (同伴),but also they are extremely particular about who they spend time with. However, snakes used to be thought of as solitary animals. They are seldom seen hanging out in groups.
A team of researchers led by Morgan Skinner and Dr. Noam Miller selected 40 non-poisonous garter snakes (袜带蛇). Ten were purchased from a snake keeper and the rest were caught in the wild. After marking each snake with a spot of color to allow for easy identification, the researchers placed ten snakes inside each of the four plastic shelters.
Skinner photographed each snake group twice a day before removing them from their shelters. After cleaning the areas thoroughly to rid them of any familiar smells, the reptiles were rearranged into different groups, and returned to the enclosure. A camera fixed over the shelters allowed the scientists to track the animals' movements for a total of eight days.
When Skinner and Miller analyzed the images, they found that regardless of where they were placed, the snakes always slipped back to their origin al "friends" forming groups of three or eight inside the small shelters. “They can tell others apart,” Miller said.
Gordon Burghardt, a biologist, says, "The study should help convince people that snakes have more social intelligence than most of us realize."
Miller believes the research could help with snake protection efforts. Endangered snake species relocated to safer habitats often leave these areas. Now, conservationists may be able to avoid that by transferring entire snake groups to the new location. Alternatively, they could also spray (喷洒)the new habitat with the species' smells to make transplants feel at “home."
1.What does the underlined word "solitary" mean in paragraph 1?
A.Causing fear. B.Existing only in small numbers.
C.Causing death or illness. D.Enjoying being alone.
2.What can we learn from the last paragraph?
A.The findings can contribute to snake conservation.
B.Snakes like to spray smells on the trees.
C.Snakes are easy to adapt to new locations.
D.Snakes tend to stay in safer habitats.
3.Which of the following proverbs can be used to describe the findings?
A.Barking dogs don't bite. B.The early bird catches worms.
C.Things of one kind come together. D.A friend in need is a friend in deed.
4.In which section of a newspaper may this text appear?
A.Entertainment. B.Science.

Denmark is only about half the size of South Carolina, but it produces more of its electricity from wind than any other country in the world. Denmark now gets 47% of its electricity from wind, and there will be more to come, thanks to a combination of history and policy.
Paul la Cour was a scientist and inventor who experimented with early wind power machines at the start of the 20th century. So it's not surprising that Denmark invested in building wind power the earliest. Since the 1970s, Denmark has been investing in wind energy all over the country. In the 1980s, due to a strong movement opposing nuclear power plants, Denmark increased its production of clean energy even before many other countries considered it.
Even back in 2002, Denmark took climate change warnings seriously. They drew up policies, aiming to cut fossil-fuel emissions by 20 %, which they did via renewable energy investment. Some of the world's largest companies in the field—including Vestas, which builds turbines (涡轮机),and Orsted, which specializes in offshore wind projects—are Danish, so the country has an impact beyond its borders.
The huge impact of Denmark's wind industry is important. But Denmark is a small country, so while almost 50% of its electricity from wind is admirable, it's also minor in terms of entire global impact.
While Denmark gets half its electricity from 5,758 megawatts (MW) of capacity, Spain's 23,000 MW covers just 18 percent of its electricity supply as it's a much bigger country. China is the leader in wind energy at 221,000 MW, and the U. S. is the second in the world at about 96,000 MW.
At the encl of 2019, lawmakers in Den mark set a new goal: increasing the share of electricity coming from renewable power to 100%.
1.What can we know about Demark?
A.It is a leader in solar energy. B.It is a pioneer in clean energy.
C.It is a victim of climate change. D.It is an advocate of nuclear energy.
2.What is Denmark government's attitude towards fossil-fuel energy projects?
A.Indifferent. B.Opposed.
C.Positive. D.Ambiguous.
3.Which country produces the most wind energy in the world?
A.China. B.Spain.
C.The U. S. D.Denmark.
4.What is the best title for the text?
A.Denmark Has a Long History of Developing Renewable Power
B.Denmark's Government Pushes ahead with Fossil-fuel Projects
C.Denmark Has a Great Effect on World's Wind Power Equipment
D.Almost Half of Denmark's Electricity Comes from Wind Power

More than 30 years ago, there was a well-known boxer named Eugene Hart. Hart was heavily favored to win his next round against an ungifted boxer, Antuofermo. It was said that the only thing that Antuofermo could do was “he bled well". However, here was an important thing. He had good qualities that you couldn't see.
During the fight, Hart controlled Antuofermo, knocking him down and giving him a good beating. Antuofermo absorbed the punishment that was dealt to him by his naturally superior opponent, and he did it so well that Hart became discouraged. In the fifth round, Hart began to tire, not physically but mentally. Taking advantage of the situation, Antuofermo attacked and knocked Hart down, thus ending the fight.
When the fighters went back to their temporary restrooms, only a thin curtain was between them. Hart's room was quiet, but on the other side he could hear Antuofermo's coach talking about who would take the fighter to the hospital. Finally he heard Antuofermo saying, "Every time he hit me with that left hook (左勾拳)to the body, I thought I was going to quit. After the second round, I thought if he hit me there again, I'd quit. I thought the same thing after the fourth round. But he stopped hitting me there."
At that moment, Hart began to weep. He was crying because for the first time he under- stood that Antuofermo had felt the same way he had and even worse. And the only thing that distinguished the guy who was talking from the guy who was crying was perseverance (毅力). The coward (懦夫)and the hero had the same emotions. They're both humans.
The important question to ask yourself here is this: How does each man respond to the tough situation that they are experiencing? Maybe you are in a tough position right now or, if not, one might be coming. How will you react? Like a hero or a coward?
1.What can we learn from paragraph 1?
A.Hart was an ordinary boxer.

2.How did Antuofermo win the fight?
A.He trained hard before the fight.
B.Hart became discouraged by his coach.
C.He was confident about his boxing talent and power.
D.He dealt with the punishment properly and grasped the chance.
3.Why did Hart cry after the fight?
A.He realized he was just mentally defeated.
B.He was hurt and sent to a hospital.
C.He lost the game easily.
D.He was considered to be a coward.
4.What are Antuofermo's qualities?

You have probably heard of the Mozart effect. It's the idea that if children or even babies listen to music composed by Mozart, they will become more intelligent. A quick Internet search reveals plenty of products to assist you in the task. Whatever your age is there are CDs and books to help you taste the power of Mozart's music, but when it comes to scientific evidence that it can make you more clever, the picture is more mixed.
The phrase “the Mozart effect” was made up in 1991, but it was a study described two years later in the journal Nature that sparked real media and public interest about the idea that listening to classical music somehow improves the brain. It is one of those ideas that sound reasonable. Mozart was undoubtedly a genius himself; his music is complex and there is a hope that if we listen to enough of it, we'll become more intelligent.
The_idea_took_off,_with thousands of parents playing Mozart to their children, and in 1998 Zell Miller, the Governor of the state of Georgia in the US, even asked for money to be set aside in the state budget so that every newborn baby could be sent a CD of classical music. It was not just babies and children who were exposed to Mozart's music on purpose, even an Italian farmer proudly explained that the cows were played Mozart three times a day to help them produce better milk.
I'll leave the debate on the impact on milk yield to farmers, but what about the evidence that listening to Mozart makes people more intelligent? More research was carried out but an analysis of sixteen different studies confirmed that listening to music does lead to a temporary improvement in the ability to handle shapes mentally, but the benefits are short-lived and it doesn't make us more intelligent.
1.What can we learn from Paragraph 1?
A.Mozart composed many musical pieces for children.
B.Children listening to Mozart will be more intelligent.
C.There are few products on the Internet about Mozart's music.
D.There is little scientific evidence to support the Mozart effect.
2.Why did many people believe in the idea of the Mozart effect?
A.Because a study described it in the journal Nature.
B.Because Mozart himself was a genius.
C.Because Mozart's music is enjoyable.
D.Because Mozart's music makes people relaxed.
3.The underlined sentence in Paragraph 3 suggests that ________.
A.people were strongly against the idea
B.the idea was accepted by many people
C.Mozart played an important part in people's life
D.the US government helped promote the idea
4.What is the author's attitude towards the Mozart effect?
A.Favorable. B.Objective.
C.Doubtful. D.Positive.

Communicating effectively means more than knowing what to say and when to say it. Communication involves the subtle signals your body language sends to those who are watching. Here are some common body actions and the impressions they create:
● Fiddling (好动) — Playing with your watch or a pen looks like you’re bored or impatient.
● Clock watching — It looks like you’re to move on to something else.
● Tapping — Tapping your feet or fingers suggests you are impatient or nervous.
● Staring — An unblinking (不眨眼的) stare conveys threatening or violent behaviour.
● Legs crossed or body hunched (弓背,耸肩) — Closing up your body profile — becoming smaller — looks like you lack confidence.
● Arms crossed — If you keep your arms folded during communication, you appear to be defending yourself against the others.
● Touching your face — When you have your hand in front of your mouth, you appear very shy.
● Rubbing your nose, looking away — People who are lying often rub their nose or look away when speaking.
● No eye contact — If you won’t look the other speaker in the eye, you seem to have low interest or a lack of confidence. (Don’t forget staring above.)
How you communicate with your body language is just as important as what you say. Watch your body language and control the unconscious messages you might be sending.
1.According to the passage, effective communication includes all of the following EXCEPT _____.
A.knowing what to say
B.sending unconscious messages to other people

It is every kid’s worst nightmare and six-year-old Jaden Hayes has lived it - twice. Firstly, he lost his dad when he was four and then last month his mom died unexpectedly in her sleep.
“I tried and I tried and I tried to get her awake - I couldn't,” said Jaden. Jaden was understandably heartbroken.
But there was another side to his grief. A side he first made public a few weeks ago when he told his aunt, and now guardian, Barbara DiCola, that he was sick and tired of seeing everyone sad all the time. And he had a plan to fix it.
“And that was the beginning of it,” said Barbara. “That’s where the adventure began.”
Jaden asked his aunt Barbara to buy a bunch of little toys and bring him to downtown Savannah, Georgia near where he lives, so he could give them away.
“I’m trying to make people smile,” said Jaden.
Jaden targeted people who weren’t already smiling and then turned their day around. He’d go out on four different occasions now and he was always successful. Even if sometimes he didn’t get exactly the reaction he was hoping for.
It was just so overwhelming to some people that a six-year-old orphan would give away a toy- expecting nothing in return - except a smile.
“I’m counting on it to be 33, 000,” said Jaden. When asked if he thought he could make that goal, he answered, “I think I can.”
1.Why did Jaden give the toys to other people?
A.Because he wanted to fix the toys.
B.Because he wanted to see more people.
C.Because he wanted to give the toys away.
D.Because he wanted to make people happy.
2.What can we learn from the passage?
A.Jaden lived with his aunt.
B.Jaden targeted people who were not happy.
C.Jaden got nothing he wanted all the time.
D.Jaden was sick and tired of seeing everyone.
3.Which of the following words can best describe Jaden?
A.Helpful and impatient. B.Creative and tricky.
C.Optimistic and courageous. D.Ambitious and greedy.
