Automakers around the world, from Japan to Texas, are struggling with a global shortage of computer chips. Volkswagen sounded the alarm about the growing problem last month. Now more automakers are reporting problems that are trimming production plans based on their supply of semiconductors (半导体).
Semiconductors are at the heart of our phones and computers, but they're critical components for new cars, too — and not just in fancy touchscreens. "They're controlling the engine and the emissions and even in the switches for raising and lowering your windows," says Kristin Dziczek, the vice president at the Center for Automotive Research.
Last year, when auto manufacturing was suspended for the pandemic, everyone predicted a prolonged slowdown in car sales. The global semiconductor industry planned accordingly, and arranged to sell more computer chips to other buyers. But then, much to everyone's surprise, shoppers were still eager to buy new cars. As soon as they reopened, plants resumed normal production at a remarkable speed.
At the same time, demand for chips from other sectors — like consumer electronics — was also increasing. "Every school district in the country had to buy new computers," Dziczek says.
For car shoppers, this could mean some vehicle models are harder to find for the next few months. So far, the consequences have been uneven among automakers. Ford and Fiat Chrysler have entire plants on pause, while General Motors says its manufacturing operations have not been affected, and Toyota does not expect any impact to employment. The United Auto Workers, which represents factory workers at Ford, GM and Fiat Chrysler plants, notes that its contracts include "unemployment and supplemental pay" for workers affected by production downtimes.

【推荐1】Did you know that more than 40 percent of all deadly car accidents occur at night? A recent break through eyeglass technology has made it safe to drive at night. It's almost like having "X-ray" vision(视力) while driving.
Spend money on your safety and peace of mind behind the wheel with a pair of these cutting-edge night driving glasses. The amount of car accidents that occur at night is mostly the result of poor visibility. Even with 60% less traffic on the road at night, accidents still happen due to blinding light and just overall bad driving visibility.
Imagine being able to clearly see what's in front of you and what's approaching, even if it's very dark and foggy. Once you start wearing ClearView night glasses, you'll feel much more confident and safe driving when it's getting dark. With ClearView you will notice an instant reduction in strong light from oncoming traffic and bright street lights.
This is because the special yellow lens tint(镜片色彩)can block strong blue light, and increase contrast(对比). ClearView passes the global traffic light standard for safer sharper vision at night with flying colors.
You can start using ClearView immediately even if you wear glasses. Simply place ClearView on top of your glasses and be amazed by the difference this technology makes!
Is it worth it? Absolutely! Keep a pair in each of your cars to make sure you have your glasses at hand when night comes. If you care about your family's safety then this is a no-brainer.

【推荐2】PARKINSON’S DISEASE is a progressive disorder caused by the deaths of neurons(神经元) in parts of the brain. Symptoms include loss of motor control, mood disturbance and ruined sleep. Although it is incurable, early medical treatment can, however, relieve these symptoms and lengthen survival.
Unfortunately, the early signs of Parkinson’s vary from person to person and there is no specific test at the early stage. A study published in ACS Omega, by Chen Xing and Liu Jun at Zhejiang University, in China, describes an invention which may be able to detect Parkinson’s before the beginning of the symptoms. The device in question is an artificially intelligent electronic nose.
The two researchers set about building this nose in 2019. That was when they heard reports of Joy Milne, a nurse, who could detect people with Parkinson’s from a distinctive smell they gave off. Researchers working with her found that the sebum(皮脂) of those with Parkinson’s has unusually high level of certain compounds. When these are acted on by cells which live naturally on the skin, the result is the mysterious smell.
This can be detected using a laboratory technique called GCMS, which is promising. Unfortunately, it is still too complex and expensive to be used daily in clinics. However, Dr. Chen and Dr. Liu invent a machine not much bigger than a toaster. It turns a sample of sebum into a steam that is then detected with sound waves. Different mixtures have different effects on the waves, and, with a bit of training, a computer loaded with an appropriate piece of artificial intelligence can learn to recognize the pattern associated with sebum from Parkinson’s patients.
The researchers tested their system on samples from 43 people with Parkinson’s disease and 44 who were healthy. They found it could correctly identify a Parkinson’s patient as having the disease about 70%. That is not yet as good as Mrs. Milne’s nose. If its reliability can be improved, its potential cheapness of the system may eventually prove an advantage for the early diagnosis of the illness.

【推荐3】A team of Japanese scientists has discovered genes that enable rice to survive high water, providing hope for better rice production in lowland areas that are affected by flooding.
The genes, called SNORKEL genes, help rice grow longer stems to deal with higher water levels. Deepwater rice generally produces low-yield rice plants. But the researchers report they have succeeded in introducing the genes to rice varieties that are higher-yield.
According to the report, as water levels rise, accumulation of the plant hormone(激素)makes the SNORKEL genes stat working, making stem growth more rapid. When the researchers introduced the genes into rice that does not normally survive in deep water, they were able to rescue the plants from drowning.
Motoyuki Ashikari, who headed the project, aid his team is hoping to use the gene on long grain rice widely used in Southeast Asia to help stabilize production in flood areas where rice with the food-resistant gene is low in production--about one-third to one-quarter that of regular rice.
"Scientifically the gene that we found is are but clear proof of a biological ability to adapt to a difficult environment, " he said. "It's a genetic strategy specifically to survive flooding. "
High water levels in rice field can be a serious problem. In some areas, rains can cause water levels to rise dangerously high during the growing season and flash flooding can fully submerge plants for days or even weeks.
Rice is a main food for billions. and while productivity has increased dramatically since the 1960s, yields must be doubled to meet projected requirements by 2050. More than 30 percent of Asian and 40 percent of African rice land is either lowland field or deep water field.
Laurentius of Utrecht University said the study is significant because high-yield rice varieties cannot survive extremes of foods. "The introduction of these genes into high-yield varieties, using advanced breeding strategies, promises to improve the quality and quantity of rice, "he said.

【推荐1】An 18-year-old US girl gained unexpected appreciation and a surprise after she gave “extra help” to an elderly man in the restaurant she was working.
It's social media that made her seemingly small action go viral and brought her appreciation from hundreds of thousands of strangers and a scholarship to Texas Southern University.
The heroine Evoni Williams has reportedly been working full-time to earn money for further study in a restaurant in La Marque, Texas, the United States. It was last week when an old man named Adrian Charpentier asked for help to chop his ham for his hands were weak because of illness. On that busy morning when she had loads of work on shoulder, Williams helped the man without hesitation. The moment she was leaning over the counter and cutting the ham was shot by a customer known as Laura Wolf.
Wolf posted the picture on the Internet and wrote, “I'm thankful to have seen this act of kindness and caring at the start of my day while everything in this world seems so negative. If we could all be like this waitress and take time to offer a helping hand. . . ” According to local reports, Wolf didn't know Williams, neither did Williams know her act was shot and shared on the web. However, the small act of kindness soon accumulated its own power on and outside the Internet.
Besides praise from netizens and media reports across the United States, a 16000-dollar scholarship to Texas Southern University was recently granted to Williams to support her study plan on business management.
“We wanted to reward Evoni's act of kindness and let her know that good deeds do not go unnoticed,” said Melinda Spaulding, an administrator at Texas Southern University.

It’s easy to find reasons to allow some physical punishments. One issue is that many parents find it very difficult to abandon physical punishment completely. Parents argue that this was the way they were brought up and that it didn’t do any harm to them. They believe that for the child’s sake they have the right to discipline the child in any way they consider fit, including using some physical punishments. The other one is that physical punishment can be quick and effective. There is not much point reasoning with a screaming child in the supermarket.
However, there are several reasons why we should stop using physical punishment. One point is that most parents are not trained to deal with misbehaving children. They don’t have enough resources or choices to handle the situation. As a result, they immediately react by hitting the child even if there are other solutions to the problem. Another point is that unless people are challenged or forced to change their belief, they may keep following negative habits. An example is seat belt use —now most people wear seat belts without thinking, while years ago the idea of using seat belts was strange to most people. In the same way, banning physical punishment will force people to change their habits.
In conclusion, parents have to change some of their belief and ideas about how children should be raised. It is possible to avoid the use of physical force, and doing so will help us move closer to the dream of removing violence from our society.

【推荐1】Carefully play with pets
Do you have a pet? Many children like pets and even treat them like humans sometimes. They may like to kiss or hug (拥抱) their pets. But this can make you sick, according to Daily Mail.
Kissing or hugging pets such as dogs and cats can cause people to take in drug-resistant bacteria (耐药细菌), British scientists said.
Many pet owners give their pets antibiotics (抗生素) when they get sick. But taking antibiotics too often can affect (影响) the bacteria inside your pct. The bacteria can become drug resistant. When people kiss or hug their pets, this kind of bacteria can move to them and make them sick.
Close relationships between pet owners and their pets are important. But if pet owners follow the rules below, they will not get sick.
Rules for playing
·Do not kiss your pets on the mouth.
·Do not let your pets lick (舔) your mouth or nose.
·Wash your hands after touching and playing with your pets.
·If you have a wound, cover it. This way, bacteria cannot pass on to you from your pet.

【推荐2】The baby monkey is much more developed at birth than the human baby. Almost from the moment it is born, the baby monkey can move around and hold tightly to its mother. During the first few days of its life the baby will approach and hold onto almost any large, warm, and soft object in its environment, particularly if that object also gives it milk. After a week or so, however, the baby monkey begins to avoid newcomers and focuses its attentions on "mother" — the real mother or the mother-substitute.
During the first two weeks of its warmth is perhaps the most important psychological thing that a monkey mother has to give to its baby. The Harlows, a couple who are both psychologists, discovered this fact by offering baby monkeys a choice of two types of mother-substitutes — one covered with cloth and one made of bare wire. If the two artificial mothers were both the same temperature, the little monkeys always preferred the cloth mother. However, if the wire model was heated, while the cloth model was cool, for the first two weeks after birth the baby monkeys picked the warm wire mother-substitutes as their favorites. Thereafter they switched and spent most of their time on the more comfortable cloth mother.
Why is cloth preferable to bare wire? Something that the Harlows called contact comfort seems to be the answer, and a most powerful influence it is. Baby monkeys spend much of their time rubbing against their mothers’ skins, putting themselves in as close contact with the parent as they can. Whenever the young animal is frightened, disturbed, or annoyed, it typically rushes to its mother and rubs itself against her body. Wire doesn’t "rub" as well as does soft wire cloth. Prolonged "contact comfort"with a cloth mother appears to give the babies confidence and is much more rewarding to them than is either warmth or milk.
According to the Harlows, the basic quality of a baby’s love for its mother is trust. If the baby is put into an unfamiliar playroom without its mother, the baby ignores the toys no matter how interesting they might be. It screams in terror and curls up into a fury little ball. If its cloth mother is now introduced into the playroom, the bay rushes to it and holds onto it for dear life. After a few minutes of contact comfort, it obviously begins to feel more secure. It then climbs down from the mother-substitute and begins to explore the toys, but often rushes back for a deep embrace as if to make sure that its mother is still there and that all is well. Bit by bit its fears of the new environment are gone and it spends more and more time playing with the toys and less and less time holding on to its "mother".

【推荐3】As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease — especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious foods, who feels OK but exercises only occasionally, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.
The field of medicine has not traditionally distinguished between someone who is merely “not ill” and someone who is in excellent health and pays attention to the body’s special needs. Both types have simply been called “well”. In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively attempting to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body’s condition. Most importantly, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap (缺陷) may be “well”. In this new sense, if they make an effort to maintain the best possible health, they can in the face of their physical limitations. “Wellness” may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can struggle for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial influence on the ways in which people face the challenges of daily life.
1. Today’s medical care is placing more stress on ________.A.keeping people in a healthy physical condition |
B.monitoring patients’ body functions |
C.removing people’s bad living habits |

【推荐1】Your colleague’s sharp comment keeps replaying in your mind. Two of your students are trapped in a “he said/she said” battle. When you reflect on your emotional reactions, you sometimes get caught up in cycles of negative feelings, which can make you feel even worse. If so, the answer may lie in a skill called “self-distancing”, the ability to take a step back and view yourself more objectively. According to a research, when people adopt self-distancing while discussing a difficult event, they make better sense of their reactions, experience less emotional suffering, and display fewer signs of stress.
But what might self-distancing look like in action? Consider a typical “he said/she said” student conflict where they are each focusing on their own feelings. One is thinking, “I can’t believe he did that to me.” And another insists, “She really hurt my feelings.” However, if you ask them to take the self-distancing, they might step outside of themselves and ask broader questions: “Why was he so hurt in this situation?” or “How did her anger affect him?”
Although this approach may sound too simple to be effective, studies indicate that a change in point of view can have a powerful effect on the way people think, feel, and behave. Here are several different techniques you can try.
First, consider how a thoughtful friend might respond after quietly observing their situation. Besides, avoid using the pronoun “I”. Focus on using third-person pronouns, he, she, they, and they were able to see the stressful event as challenging rather than threatening. Finally, ask yourself, “How would I feel about this one week from now or ten years from now?” This form of mental time travel may be effective because our attention is directed away from our immediate, concrete circumstances.

【推荐2】How to Study Smarter, Not Harder
Here are some of our favorite study tips that will help any student study smarter, not harder:
Recite As You Study
Reciting----saying things out loud should first take place as you read through each paragraph or section. Test yourself. This will help you to understand as well as learn faster because it is more active than reading or listening.
It will also help you to notice your mistakes and the topics you have trouble understanding.
Take Fuller Notes
Notes should be in your own words, brief and clear. They should be tidy and easy to read. Writing notes will help you better than just underlining as you read, since it forces you to rewrite ideas in your own words.
Study the Middle
The best time to review is soon after you’ve learned something. You are more likely to remember the material at the beginning and the end of the lesson, so make sure you focus on the middle when you review.
Sleep On It
Study before going to bed, unless you are very tired. It's easier to remember material you have just learned after sleeping than after an equal period of daytime activity, because your brain continues to think even after you’ve fallen asleep.
Combine(结合) Memory and Understanding
There are two ways to remember: by memorizing and by understanding. Multiplication tables, telephone numbers, and math formulas are better learned by rote(死记硬背). Ideas are best learned by understanding.
The more ways you have to think about an idea, the more meaning it will have; the more meaningful the learning, the better you can remember it. Pay attention to similarities in ideas and concepts, and then try to understand how they fit in with things you already know. Never be satisfied with anything less than a completely clear understanding of what you are reading. If you are not able to follow the thought, go back to the place where you first got confused and try again.
1. You can notice your mistakes by ______.A.speaking things out aloud |
B.studying the middle |
C.taking notes |
D.sleeping on it |
A.underline important notes |
B.write as quickly as possible |
C.write notes in your own words |
D.take down every detail |
A.Thinking about an idea in different ways. |
B.Going back to what first made you confused and start again. |
C.Relating ideas and concepts with what you already know. |
D.Reading from the beginning to the end without stop. |
