Spring has come with all its beauty! Trees have turned green or flowers can be seeing everywhere. Last Friday, my friends and me went on a spring outing. It was such a great fun! We cycled along the streams and down the paths. It didn't take us long to get the foot of the mountain, when we left our bikes. Then we begin hiking. As we reached the top of the mountain, we were shocking to see many plastic bottle and food bags here and there. All of us started to collect the rubbish and then took it down the mountain. We felt happily to have done our part for the environment.

(large) high-speed rail network.

Most high-speed rail tickets have corresponding (对应的) seats, and only 9. small number of standing tickets are sometimes sold on limited trains. There's never a crowd of people sitting in the aisles. The ticket prices for China high-speed trains are reasonable and, on most routes, the frequency of departure is very high, so people can buy tickets10.(convenient).

    Have you ever used any language learning apps? If you want to learn a language and speak it right away, modernize your learning style and adopt an app. It doesn't cost much, but it's worth a lot. 1.

● Learn anywhere and anytime

Personally, I love to review my vocabulary quietly in my bed before sleep using a language learning app. 2. Of course, it's also possible to learn a language with a book, but it's so much more entertaining when you are using a language learning app!

● Never waste time again

3. More often than not, we will get really annoyed or even stressed when time is wasted. However, when using a language learning app, time seems to go by quickly. We can take the opportunity to review and play a little while we have to wait around.

● 4.

Have you ever taken up a course at night? I have, but I found it hard to complete it because there were many restrictions. I was required to attend classes twice a week on a fixed schedule. But when we study on our own with a language learning app, we can study at our own pace.

● Save your money

Most language schools haven't evolved to meet the needs of modem society. And that's before we've even begun to talk about the price, which is often quite unaffordable. 5. But the benefits are huge, offering you the freedom and independence to learn at very little expense.

A. Quicken your progress

B. Work without restrictions

C. Mobile apps can handle complex applications

D. Learning with the help of an app doesn't cost much at all

E. When I travel, I also use it to listen to some podcasts (播客)

F. We all have the experience of waiting for an appointment or a bus

G. Here are some benefits of language learning apps used on smart phones

    "Acting is the least mysterious of all crafts," Marion Brando once said. But for scientists, working out what is going on in an actor's head has always been something of a puzzle.

Now, researchers have said actors show different patterns of brain activity depending on whether they are in character or not.

Dr Steven Brown, from McMaster University in Canada, said, "It looks like when you are acting, you are suppressing (压制) yourself; almost like the character is possessing you."

Brown and colleagues report how 15 actors, mainly theatre students, were trained to take on a Shakespeare role — either Romeo or Juliet — in a theatre workshop. They were then invited into the laboratory, where their brains were scanned in a series of experiments.

Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party? And would they tell their parents that they had fallen in love?

Each actor was asked to respond to different questions, based on two different premises (前提). In one, they were asked for their own perspective, while in the other, they were asked to respond as though they were either Romeo or Juliet.

The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some third-person knowledge or inferences about their character.

The team said they also found additional reduction in activity in two regions of the prefrontal cortex (前额皮质) linked to the sense of self, compared with when the actors were responding as themselves.

However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than "pretending" to be someone — it involves embodying (体现) the text and language.

1.How did Dr Brown's team conduct their research?

A. By scanning the brain activity of some actors.

B. By doing a survey with some theatre goers.

C. By interviewing some theatre teachers.

D. By consulting some experienced researchers.

2.What is the finding of Dr Brown's research?

A. Acting is not as mysterious as people think.

B. Actors' brain activity differs when they are acting.

C. Acting is far more than pretending to be the character.

D. Actors' brain activity is more active when they are in character.

3.How did Philip Davis react to the research?

A. He supported it. B. He doubted it.

C. He explained it. D. He advocated it.

4.What is the text mainly about?

A. A debate of how the brain functions.

B. A play written by Shakespeare.

C. A research on the brain activity of actors.

D. A report of the cooperation of scientists and actors.
