    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.
