    Talking to yourself may seem a little shameful. According to the well-known saying, talking to yourself is the first sign of madness, 1. Talking to ourselves, whether out loud or silently in our heads, is a valuable tool for thought.

Far from being mentally ill, self-talk allows us to plan what we are going to do, manage our activities, regulate our emotions and even create a description of our experience.2.

As children, according to the Russian psychologist Lev Vygotsky, we use private speech to regulate our actions in the same way that we use public speech to control the behavior of others.3. Psychological experiments have shown that the private speech can improve our performance on tasks ranging from judging what other people are thinking to sorting images into categories. One recent study suggested that self-talk is most effective when we address ourselves in the second person, as “you” rather than “I”.

4. If you want proof, turn on the sports channel. You’re certain to see an athlete or two cheering themselves up with a bitter phrase or scolding themselves after a bad shot.

Conduct a dialogue with ourselves.5. The private speech seems to be a particularly good way of solving problems and working through ideas. The to-and-fro between different points of view means our thoughts can end up in expected places, just like a regular dialogue can, and might turn out to be one of the keys lo human creativity.

A.What is private speech?

B.Bui there is no need for embarrassment.

C.Psychologists refer to this as private speech.

D.Ask questions of the self and provide answers.

E.We do a lot of private speech when we are young.

F.As we grow older, we make the private speech become the way of blinking,

G.Although the private speech is effective, we never entirely put away the out-loud speech.

    This may sound like a joke about a lazy person's dream job. Earn big money by staying in bed and watching TV. But this is really happening, and it's a project of NASA and two European space agencies the Institute of Aerospace Medicine at the Cologne-based German Aerospace Center and the European Space Agency. It's called Artificial Gravity Bed Rest Study, aimed at studying how the body adapts to weightlessness in space.

Scientists are seeking 12 women to spend two full months in bed in the fall at a German lab, plus an additional month there for preparation and recovery. The first 12 test subjects, all men, already have started the study.

Participants spend two entire months in bed and remain lying down even to do everyday things like eating, drinking and exercising. They also answer nature's call and shower, but it's unclear from the NASA website how those tasks are accomplished in bed.

"Daily routine showering, getting dressed, eating, exercising takes much time when you cannot stand up to do them," says the website, adding that there is "continuous data collection", including blood pressure, heart rate, nutrient absorption and also the participants' feelings. Study subjects will spend the 60 days with their heads tilted(倾斜)down six degrees, which imitates(模仿)conditions in space.

Participants are encouraged to pass the time by watching TV, taking online courses, reading and any other activities they can perform while lying down alone in bed to relieve what could be boredom. Family and friends are allowed to visit.

The high $ 18,500 payment for two months of lazing about is probably a major motivation for people willing to go through something this extreme. However, if you're an American who really needs the money, you probably can't afford it. Candidates need to travel to Cologne four times at their own expense for the employment process between April and July. Plus, they need strong German-speaking skills. Also participants need to be nonsmokers between ages 24 and 55, in good health, with normal body weight.

1.What are participants expected to do during the study?

A.Report their feelings regularly. B.Complete their daily routines in bed.

C.Keep their bodies tilted down six degrees. D.Record their physical responses every day.

2.What data about the participants will the researchers collect?

A.The changes in their weight. B.Their behaviors to weightlessness.

C.The ways they do their daily things. D.Their physical and mental reactions

3.What will be a challenge for the participants?

A.The language skills they need. B.The difficulty meeting family.

C.The possibility that they feel dull. D.The slow discovery of their health.

4.The requirements for potential participants are        .

A.challenging for Americans B.tailored to thin persons

C.easy for the youth to satisfy D.suitable for most people
