TOKYO—Lonely astronauts on the International Space Station (ISS) may soon be getting a robot friend from Japan.

Japan's space agency is considering putting a talking humanoid(有人的特點(diǎn)的) robot on the ISS to watch the work while astronauts are asleep, monitor their health and stress levels and communicate to Earth through the micro?blogging site Twitter.

Japan's space agency JAXA announced this week that it is looking at a plan to send a humanoid robot to the space station in 2013 that could communicate with the ground through Twitter—primarily feeding photos, rather than original ideas —and provide astronauts with “comfort and companionship”．

Following up on US NASA's “Robonaut” R?2 program, which is set for launch on the Discovery shuttle next week, the Japanese robot would be part of a larger effort to create and refine robots that can be used by the elderly, JAXA said in a statement.

Japan is one of the leading countries in robotics and has a rapidly aging society with one of the world's longest life expectancies.

Improving robot communication capabilities could help elderly people on Earth by providing a nonintrusive(無干擾的) means of monitoring the robot owner's health and vital signs and sending information to emergency responders if there is an abnormality, JAXA said.

“We are thinking in terms of a very human?like robot that would have facial expressions and be able to talk with the astronauts，” said JAXA's Satoshi Sano.

The robot was being developed with the advertising and communications giant Dentsu Inc and a team at Tokyo University.

The NASA project has a human?like head, hands and arms and uses the same tools as station crew members. The “Robonaut” called R?2 is intended to carry out maintenance tasks in the station's Destiny lab.

NASA says it hopes that humanoid robots could one day stand in for astronauts during spacewalks or perform tasks too difficult or dangerous for humans.

For now, the $2.5 million NASA robot is limited to activities within the lab.

1. According to the passage, a humanoid robot, put on the ISS, shall carry out the tasks except ________.

A. keep in contact with Earth

B. get a friend for astronauts from Japan

C. take care of the ISS sometimes

D. keep an eye on the health of the astronauts

2.Which of the following statements is TRUE according to this passage?

A. NASA is planning to communicate with the space station through Twitter.

B. Japan has the largest number of elderly people.

C. The robot program will eventually benefit the elderly.

D. R?2 program is in the charge of Japan's JAXA.

3.From the passage we can know ________.

A. robots could completely take the place of human astronauts in the future

B. the robot program, having cost $2.5 million, can carry out all tasks

C. many Japanese universities joined in the robot program

D. future astronauts will become less lonely and more comfortable with the help of the robot

Dear Mike,

How are you doing these days?

Aimed at providing a platform there students can have a chance to exchange and make use of their books, the annual campus books fair will soon held in our school. The fair will attract a huge crowd from the entirely school, who are to sell, purchase but exchange their second-hand books with their peers.

As a regular visitor, I’ve found myself increasingly drawing by the fair. For one thing, the fair exhibits books of hundreds of type on diverse topics, motivating us to further develop their reading habits and help to broaden our horizons. For other, most books are sold at a low price than what the bookstores offer.

Please let me to know if you have any suggestions on how to host such a book fair better.
