Science。And technology students in China and the US  have a1ong way to go before they call develop a deep understanding of scientific reasoning,researchers have found．

    As part of a research to compare science education in China and the US，LeiBao,a professor

 from the Departmenr of Physics of the Ohio State University, gave 5,760；freshmen in three US and four Chinese univeristies two tests to evaluate content knowledge  and another to assess scientific reasoning

     Though Chinese students did better than their US counterparts in the first two tests that

Emphasized on learning facts,both groups “scored relatively poorly”on the third test,designed to

 Assess their ability ot systmatically explore a problem , the results showed.

    Lei Bao said that the finding challenges conventional wisdom，which holds that teaching

 science facts will improve students’reasoning ability．“Our study shows that ,contrary to what many  people would expect，even when students are thoroughly taught the facts，they don’t necessarily develop the reasoning skills they need io succeed．’’IBao said：‘“Because students need both knowledge and reasoning,we need to explore teaching methods that target both．”

    ‘The current education systems and asessment of China and the US do not emphasize on deep understanding of scientific reasoning in the disciplines of science；technology,engineering and mathematics(STEM)，the study concluded．

    Bao explained that reasoning is good skill for everyone topossess-not just scientists and

 engineers：The general public also need good reasoning skills in order to correctly interpret

 scientific findings and think rationally．STEM students need to excael at scientific reasoning in order to handle open-ended real-world tasks in their future careers in science and engineering．

    How to boost scientific reasoning?The study suggests that educators must go beyond teaching science facts if they hope to boost students’reasoning ability．Bao points to inquiry-based leaming.where students work in groups，question teachers and design their owu investigations．This teaching technique is growing in popularity worldwide．

    A．Chinese students and their US counterparts did poorly in the first two tests

    B．Chinese students did beaer than their US counterparts in alI the three tests

    C．Chinese students did beaer than their US counterparts in the first two tests    ‘

    D．US students did beaer than their Chinese counterparts in the third test

 68．The conventional wisdom holds that            ．

    A．the more facts~tudents are taught，the more reasoning skills they will acquire

    B．the general public also need reasoning skills to interpret scientific findings

    C．to boost students’reasoning ability,educators must explore teaching methods

    D．the current education Systems are harmful to improve students’reasoning ability

 69．Based on the study,what will be done to improve students’reasoning ability?

    A．To improve teaching techniques．        B．To better students’learning conditions．

    C．To teach students more science facts．    D．To offer students more tests．

70．The underlined phrase“excel at”in Paragraph 6 probably means        ．

    A．be worse at    B．be beaer at    C．be enthusiastic about D．be inferior to

 71．Which of the following is correct according to the passage?

    A．Little needs to be done to develop students’reasoning ability in the US．

    B．Only scientists and engineers need reasoning abilities．

    C．Two tests were carried out to evaluate students’scientific reasoning．

    D．Inquiry-based learning is a good way to boost students’reasoning ability．

What science fiction once told of other worlds far away is now a fact. Astronomers prove another solar system like ours with some planets in the constellation (星座) Andromeda ( 仙女座).

Geoffrey Marcy is a professor of astronomy and physics at San Francisco State University and says, “What we have found now, for the first time ever, is indeed a fully-grown system of planets around the star Upsilon Andromeda. It appears to have three planets, one close in, one at a middle distance, and one farther out.” The star is slightly larger than our sun. The planets are huge, like our Jupiter(木星)

Marcy’s partner in this research, Debra Fischer, describes the solar system, “Here’s the inner planet that goes around every 46 days, the middle planet that goes around every 242 days, and then the outer planet that goes around every three and a half to four years.”

Astronomically, it’s not far away, 44 light years. The sun of that solar system, Upsilon Andromeda, is so near and bright that it can be seen by using no equipment during summer and fall.

For twelve years astronomers searched the skies in the belief that if our sun has planets around it, surely others do, too. Geoffrey Marcy says, “And then starting three and a half years ago, we began finding for the first time planets singly, one planet here around one star.”

“When I look up at the stars now at night, I can imagine easily that every one of them has planets around them,” says Debra Fischer.

It was a tremble in the star that led Marcy to the planets. “The star rocks around due to the gravity of the planet much like a dog owner gets pulled around by a little dog.”

Can they support life? We don’t know, because present technology is not advanced enough to determine what the planets are made of. “That,” Marcy says , “is astronomy’s next challenge.”

1. What’s the relation between Andromeda (A), Upsilon Andromeda system (U) and the mentioned planets (P) ?

2. According to Debra Fischer, in the new solar system, ________.

   A. the larger a planet is, the shorter it takes to go around the star.

   B. it takes all the planets around three and a half to four years to go around the star

   C. the planets move around the star at uneven speeds

   D. the farther a planet is from the star, the longer it takes to go around the star

3. What led to Marcy’s discovery of the planets?

   A. The tremble of Upsilon Andromeda.     

B. That any planet has gravity.

C. That he believes any star has its planets.  

D. that he found a dog owner was pulled by his dog.

4. We can infer that the scientists are           .

   A. to find means to communicate with the living beings on the planets

   B. to find means to travel to the planets

   C. soon to be able to answer the question of whether there is life on these planets

   D. to find out whether the planets can support life.
