Planet Hunter
When Geoff Marcy was 14； his parents bought him a telescope。 Every night； he would go onto the roof outside his window to see the wonders of the sky。
“What excited me most was whether there were planets（行星）in other solar（太阳的）systems where life might exist； ”he says。 “I decided to try to find planets orbiting（沿……轨道运行）other stars like our Sun。”
And he did。 “My fellow researcher； Paul Butler； and I found our first planet in 1995； ”Dr。 Marcy says。 “We worked for ten years without finding anything！ But we stuck to it； and our patience paid off。 ”
Since then； the two scientists have discovered 65 of the more than 100 planets found orbiting other stars。 Dr。 Marcy and Dr。 Butler also spotted the first “family”of three planets。 In June 2002 they announced another discovery： a Jupiter…like（像木星一样的）planet orbiting star 55 Cancri。
At first； the two researchers found only planets that orbit close to stars。 Recently； the scientists found planets farther out。 The planet orbiting 55 Cancri is a major breakthrough： it is the first sighting of a large gas planet about the same distance from the star as Jupiter is from the Sun。
Why is this important？ Scientists think that life on Earth may exist because of two special features（特征）in our solar system。 The first is Jupiter。
“Because It’s so big； Jupiter pulls comets and asteroids（小行星）； or they all come and hit the Earth。 ”Dr。 Marcy explains。 “Without Jupiter； life on Earth would likely have been destroyed。 ”
A second feature is that Earth is a rocky planet where liquid water； which is necessary for life； can exist。 Unlike gas planets； rocky planets like Earth have surfaces where water can gather in pools and seas； which may support life。 A huge space exists between the Jupiter…like planet and two other planets that lie close to 55 Cancri。 Is there an Earth…like planet in the space； too small for us to notice？ If so； says Dr。 Marcy； “We would have two striking similarities to our solar system： a Jupiterlike planet and an Earthlike planet。 And there may be life！ ”

When Rikke in Denmark goes to get some milk from the fridge； she has trouble getting past the refrigerator door。 But It’s not because of any physical obstruction （障碍）。 It’s usually because the PC monitor in her refrigerator’s door has informed her that a new email message has arrived。
Rikke and her husband are taking part in a six…month trial sponsored by a Danish firm and two Swedish partners。 They hope to show that computers can be put to much more practical daily use than most people think。 Fifty families and singles were provided with a free model known as the “Screenfridge” for the duration of trial。
“It’s really very clever；” says Rikke。 She can call up email； news reports； sales items at the supermarket or addresses out of the endless ocean of Internet possibilities。 “I’m not the type who wants to sit in front of the computer and wait 10 minutes for the modem to connect；” she says。
The creators of the Screenfridge aim at this type of buyers。 They think that the machine should attract people who have limited time to solve technical problems or surf online。
The PC that is built into the door is very small。 It is only two centimeters wide； and completely silent。
Everything moves quickly； as Rikke admits。 “Well； the whole thing is really just an amusement；” she says。 “But when the thing is gone after the test； it will be a pain to have to go down in the basement again to download my email。”
The Screenfridge is due to hit the market before early 2005。

A。 To improve the email service。 B。 To help those who cannot use computers。
C。 To make refrigerators more useful。 D。 To make computers more convenient。
43。How long has Rikke probably been using the Screenfridge？
A。 Several months。 B。 Several years。 C。 More than a year。 D。 Several hours。
44。From what Rikke says at the end of the text we can feel that she。
A。 is sorry she has to download her email in the basement
B。 wishes she would continue to use the Screenfridge
C。 is not satisfied with all of the screenfridge
