If you live in a place where most people speak English, you may use the language for several hours each day.1.Your mind stops trying to translate things from your native language into English.
However, as an English beginner, you may live in places where English is not the main language. The good news is that thinking in English can bring you a huge step closer to fluency！The following are some mental exercises that can help.
Think in single words.
2.So, a good first step is to think in individual words. Look around you. What do you see? In your head, try to name each object in your surroundings, whatever it is and wherever you are.
Think in sentences.
The next exercise is thinking in simple sentences. For example, if you are sitting in a park, you can tell yourself things like, “3.” and “I like everything here.”
Describe your day.
You can describe your day and make plans in the morning, such as, “When I leave the house, I'm going to get an iced coffee.4.I'll hand in my homework after arriving.”
5.
When you do this, you are imagining yourself speaking to someone else. You are asking the questions and thinking of replies. For example, let's say the imaginary person asks you a question, like, “What did you do last night?” How would you answer?
A.Find a partner.
B.The air is so fresh.
C.Think in conversation.
D.Then I'll take the bus to class.
E.Your hard work finally paid off.
F.Most experts note that it's best to start small.
G.So, it may become part of your "inner speech".
One argument for why robots will never fully measure up to people is because they lack human-like social skills. But researchers are experimenting with new methods to give robots social skills to better interact with humans.
The experiment was carried out by researchers from the Massachusetts Institute of Technology(MIT). The team developed a machine learning system for self-driving vehicles that is designed to learn the social characteristics of other drivers. The researchers studied driving situations to learn how other drivers on the road were likely to behave. Since not all human drivers act the same way, the data was meant to teach the driverless car to avoid dangerous situations.
The researchers say the technology uses tools borrowed from the field of social psychology. In this experiment, scientists created a system that attempted to decide whether a person's driving style is more selfish or selfless. In road tests, self-driving vehicles equipped with the system improved their ability to predict what other drivers would do by up to 25 percent.
In one test, the self-driving car was observed making a left-hand turn. The study found the system could cause the vehicle to wait before making the turn if it predicted the oncoming drivers acted selfishly and might be unsafe. But when oncoming vehicles were judged to be selfless, the self-driving car could make the turn without delay because it saw less risk of unsafe behavior.
The MIT team plans to expand its research model to include other things that a self-driving vehicle might need to deal with. These include predictions about people walking around traffic, as well as bicycles and other things found in driving environments. The researchers say they believe the technology could also be used in vehicles with human drivers. It could act as a warning system against other drivers judged to be behaving aggressively.
1.What is the purpose of the new research?
A.To reduce human drivers' mistakes.
B.To develop a machine learning system.
C.To give robots human-like social skills.
D.To prove robots can never replace humans.
2.What caused the self-driving car to wait or turn quickly?
A.The colors of the traffic lights.
B.The orders from police officer.
C.The directions from human drivers.
D.The oncoming driver's driving style.
3.What can we learn from the last paragraph?
A.More traffic participants will be involved in the research.
B.Other colleges will be invited to join in the project.
C.New rules will be developed for road users.
D.Human drivers will give way to robots.
4.In which section of a newspaper may this text appear?
A.Entertainment. B.Science.
C.Education. D.Business.
Traditional Chinese medicine(TCM) is an ancient form of healthcare that dates back over 2,500 years, which aims to prevent or cure disease by maintaining or restoring yinyang balance. Fundamentally, TCM seeks to restore a dynamic balance between two complementary forces, yin(passive) and yang(active) . According to the yinyang theory, a person is healthy when harmony exists between these two forces; illness, on the other hand, results from a breakdown in the balance.
TCM practitioners(从业者) look to treat the root cause of disease and take a holistic approach to helping people experience complete recovery without the use of conventional drugs. TCM is “holistic” because it takes into account all aspects of a patient's life, rather than just several obvious symptoms. TCM practitioners view the body as a complex system, rather than separate organs. They use smell, hearing, touch, and pulse diagnosis(诊断) to discover the source of an unbalanced health condition. In addition, the practitioner typically makes use of what is known as five phases(wuxing) . Using the five-phase theory, the practitioner can create a plan for treatment that might contain such components as herbs, lifestyle changes, and foods for recovery.
Over the past several decades, TCM has been going global. It is now practiced in 183 countries and regions with 86 of them signing agreements with China to promote it. More and more medical schools are now recognizing the importance of training students and staff in “mind-body” practices that emphasize disease prevention and holistic treatments. A study of 3,200 physicians, conducted by Health Products Research, indicates that more than 50 percent of physicians in the U. S. planned to begin or increase use of TCM.

In Van Nuys California, a beagle(猎兔犬) was dropped off at the city pound because he was too old and had gained so much weight; the owner didn't want him anymore. The people at the shelter guessed that the beagle was 7-8 years old, so he still had a lot of life left, if he could be brought back to a normal weight.
Unfortunately, dog pounds don't have the time or resources to work an abandoned animal back into good health. Plus, people don't like to adopt animals that are terribly overweight. Without someone's stepping in, this beagle would probably have been put down by giving a drug to end his suffering.
Thankfully the good people of Karma Rescue, a non-profit organization which provides life-saving aid for pets in trouble, came to his rescue. He was given the name Darwin. Karma rescues a number of dogs, and they were still surprised at what appeared to be neglect(忽略) of the dog for its entire life.
Darwin was about twice the weight that he should have been and even had a hard time walking. Having a beagle, we know how quickly a beagle can become overweight, which puts stress on their heart and causes other health issues.
Beagles will eat anything put in front of them, and will eat it all. They don't know when or how to stop eating. We have experienced this when our beagle has gotten into our trash, gotten food on the kitchen counter, and even eaten a bag of chocolate chips. Thankfully our beagle survived his hard times and we have learned to “beagle proof(防护) ” the house when we leave.
Darwin was in for a long journey back to health, but with the support of many people, he is down to a normal beagle weight and he is well on his way.
1.The underline word “pound” in Paragraph l probably refers to a place_____________.
A.where dogs are trained to hunt B.where people can buy or sell pets
C.where sick or injured pets are treated D.where homeless dogs are temporarily kept
2.What would have happened to Darwin without Karma Rescue's help?
A.He would have been poisoned to death.
B.He would have been abandoned in the wild.
C.He would have been adopted by a kind couple.
D.He would have been returned to his former owner.
3.What may they do to “beagle proof” the house before leaving?
A.Leave all the doors open. B.Place the trash near the beagle.
C.Put all the food out of the beagle's reach. D.Build a thick and strong wall around the house.
4.What is the best title for the text?
A.The Transformation of an Abandoned Beagle
B.Karma Rescue, a Non-profit Organization
C.How to Keep Your Beagle in Shape
D.Kind People Bring Good Luck
