If you dream of going someplace warm to escape the cold winter weather, a trip to a recently discovered planet would certainly warm you right up.The planet, named OGLE-TR-56b, has temperatures of more than 3,000.“This is the hottest planet we know about.”says Dr.Dimitar Sasselov, a scientist who led the discovery team.“It is hot enough to have an iron fog and to rain hot iron droplets(細沫).”

  The new planet is 30 times farther away than any planet discovered by scientists before.It is in the Milky Way(銀河)but it is not in our solar(太陽的)system.The new planet moves around a star much like our sun, however, scientists discovered the planet by using a new planet-searching method, called“transit technique”.They were able to catch sight of the planet when it moved in front of its star, causing the star's light to dim(變暗).Scientists compare the method to discovering the shadow of a bee flying in front of a searchlight 200 miles away.“We believe the door has been opened wide to go and discover planets like Earth.”says Sasselov.

(1)

We can infer from the passage that ________.

[  ]

A.

there is iron on the new planet

B.

we could go to the new planet in winter

C.

the star could block our view of the new planet

D.

scientists are studying the weather on the new planet

(2)

The“transit technique”can ________.

[  ]

A.

help dim the light of a star

B.

help scientists with a searchlight

C.

help scientists bee on a planet

D.

help find a planet moving before its star

(3)

Which is the best title for the passage?

[  ]

A.

New Planet-searching Technique

B.

New Distant Discovery

C.

Space Searching

D.

Dream Planet

答案:1.C;2.D;3.B;
解析:

(1)

文章第一段提及該行星是我們知曉的最熱的一顆.“It is hot enough to have an iron fog and to rain hot iron droplets”描述的是高溫可以讓鐵汽化,并非說行星上有鐵,如此高溫人類也無法接近,因此排除A、B兩項;文中沒有提到科學家在研究這一行星的氣候一事,所以排除D項;文中所敘“They were able to catch sight of the planet, when it moved in front of its star, causing the star's light to dim.”“衛(wèi)星運行到其恒星前面時會使恒星的光線變暗,同理當運行到恒星后面時,自然會被其遮住”.故選C項.

(2)

“transit technique”是科學家尋找行星的新方法,文中打了比方,對著200英里外的探照燈,人們會發(fā)現(xiàn)蜜蜂飛過時的影子.同理,行星運行到其恒星前面時,也會留下陰影,從而被人發(fā)現(xiàn).因此答案選D項.

(3)

這是一道考查文章主旨大意的題目.通讀全文后,我們了解到,科學家有了最新的發(fā)現(xiàn),一顆迄今最熱的行星,以及發(fā)現(xiàn)行星的新方法.A項內容只是文章的一部分;C項內容范圍太大;D項沒有緊扣文章,故選B項.

    Edgar felt quite 1 at the 2 of his first swim of the summer.     3 the sun shining down so strongly, the sea was certain to be      4 enough. He walked quickly along the seafront towards the steps      5 led on to the sands. He smiled 6 at the passers-by. He had just     smiled and 7 his 8 to an elderly lady      9 a man with a camera caught his arm and stopped him. Edgar heard a little clicking noise from     the camera.

                   

      "Your photo, sir, in wonderful color, in just one moment if you     please," said the man in one breath.

                   

      Then he took out the      10 and held it 11 his hand and was waving     it to Edgar. In a moment he handed it over, and Edgar saw the bright     blue of his shirt half 12 the picture.     "Seventy pence, sir," the man said.

                   

         "Seventy pence," Edgar repeated 13 ," For this?" He stared      14 the photo.

                   

    "They are usually 85, sir, but for a single object I make a cut-price     offer. It's the best price 15 you'll get here."

                   

         "You'll have to make a better offer," Edgar said. It was a good photo,     he thought, so bright and clear. His hat was high, and he was smiling     broadly at the old lady, 16 arm and handbag came into a lower corner.     He had no idea that he was being snapped. He thought he was really      17 good-looking fellow.

                   

      "That's as 18 as any art job that would      19 you pounds," said the cameraman. "It's better in a way because it's so      20 . Only 70 pence, sir."

                   

      "I've never paid so much      21 a snap in my life. It simply isn't 22     that kind of money. It's not as I need the thing. Look, I'll give     you 25. "

                   

      "No, I can't do that. Each of these snaps costs me 50p, so you     see … "

                   

      "Then I'll give you 50p and that's that."

                   

         "Let me see, then." The man suddenly took the photo out of Edgar's     hand." I can't 23 any more time with you. It's 70p      24 I keep it."

              

      "Keep it," Edgar said. He turned, looked out to sea, then walked     25 away.
