【题目】D

For generations, people have dreamed of traveling to Mars to explore Earth's closest planetary neighbor. NASA and other space agencies have announced plans to send people to the Red Planet. But such a manned mission is years away.

In the United States, some volunteers are learning how people will react to months of separation from other humans on a Mars base.

What would it be like to live on the planet Mars? Volunteers are spending eight months in an area that looks much like the surface of Mars. But actually, they are living in Hawaii.

Six people are isolated high on top of Mauna Loa, a volcanic mountain on the Big Island of Hawaii. They are living on a simulated, or make-believe, Mars Base. The American Space Agency, NASA, has provided financial support for the work. The project is called HI-SEAS, or Hawaii Space Exploration Analog and Simulation.

The six member HI-SEAS crew is mostly self-sufficient. They take care of themselves. Food and supplies are brought to them. But the individuals bringing those supplies cannot communicate with volunteers inside the habitat, or base.

The current crew has been living in the habitat since October, and will stay until June. Two earlier crews lived there before them. Crew members communicate with the outside world through e-mail and blogs. They also produce videos on the YouTube website.

Crew members also are using a smartphone app, or program, that creates a 20-minute delay for communications. That would be the same as if you were communicating from Mars.

This is not the only group of volunteers with sights set on Mars. A group called Mars One has appealed for would-be Mars astronauts from around the world. Mars One is a private, non-government project based in The Netherlands.

Others believe the American or European space agencies are the most likely to put people on Mars, maybe in the 2030s, or later.

For now, on a mountaintop in Hawaii, volunteers are getting a taste of life on a future Mars base.

【题目】 Your brain isnt a muscle, but you can treat it like one

Many people focus on physical fitness, but few know that brain fitness is also something you can work on. In fact, you can exercise your brain as often as you do to your arms or legs-and the results can be positive and empowering.

To improve your brain, you can’t simply repeat the same exercises over and over. Just as lifting a two-pound weight will stop challenging you, so will repetitive exercises such as crosswords or Sudoku. Once you master easy exercises, you must move on to harder ones in order to push your brain-like your muscles-to a new level.

The science behind brain training

Scientists once believed that your mental abilities were fixed in adulthood. Since studies have shown just the opposite, millions of people around the world have adopted the new practice of brain training. The most popular of these brain training products is made by the San Francisco-based Lumosity. Lumositys scientists with an experienced team of game designers have developed a fun,effective online brain training program that measures, tracks, and adapts to your progress, so youll always be challenged.

Promising studies on the effects of brain training

In a 2013 Stanford study, a treatment group of 21 breast cancer survivors used 12 weeks of Lumosity training to work on processing speed, mental flexibility, and working memory tasks. On average, those who trained improved on tests of these abilities, compared to a group that did not train with Lumosity.

There is even some evidence suggesting that Lumosity may be beneficial to normal, healthy adults. In a 2011 study by Lumosity and San Francisco State University researchers. 13 people who trained over 5 weeks improved working memory scores by 10%and attention scores by 20%.

Brain training is designed to meet real-life needs

The design of brain train ing is targeted at real-life benefits instead of improving game scores. Better attention, for example, can mean greater focus in the classroom or at an important business meeting. With improved processing speed, you might react and adapt faster to the demands of a busy life. And a better memory could mean stronger, longer relationships with the people closest to you.

【1We can learn from the passage that _________.

A. brain training speeds up the recovery of breast cancer

B. your brain is like a muscle because it gives you power

C. people’s mental abilities can’t develop after they grow up

D. Lumosity can measure, track and suit your level as you improve

【2Which skill may brain training not improve?

A. Better attention.

C. Better writing skills.

B. A better memory.

D. Higher processing speed.

【3What can we infer from the passage?

A. People should care more about physical health instead of mental health.

B. Brain training has been proved effective through scientific researches.

C. A bad memory is the only reason for weak relationships with people.

D. Playing online games is the best way of brain training.

【4Whats the best title for the passage?

A. Brain Training Makes a Difference

B. Train Your Brain like a Muscle

C. Lumosity, Your Best Choice

D. How to Train Your Brain
