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 F.“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(xì)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 the 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

(2)

The“transit technique”can ________

[  ]

A.

help dim the light of a star

B.

help scientists with a searchlight

C.

help discover a 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)

此題考查考生進(jìn)行推理判斷的能力。文中第一段最后作者提到的iron fog只是一種比喻,用來表明這顆行星溫度之高,并不能由此推斷它的上面有鐵。A是不成立的。文中第一句話:如果你夢(mèng)想去一個(gè)溫暖的地方以躲避寒冷的冬季,那么到新近發(fā)現(xiàn)的一顆行星上去會(huì)讓你立刻暖和起來。這句話是為了引起下文,不能作為推斷的依據(jù),因此,B選項(xiàng)錯(cuò)誤。D選項(xiàng)說科學(xué)家們正在研究這顆新星上的天氣情況,文中沒有提及。文中第二段:科學(xué)家們用一種叫做transit technique的新方法發(fā)現(xiàn)了這顆新星。這顆星圍繞一顆類似太陽的恒星運(yùn)轉(zhuǎn),當(dāng)它轉(zhuǎn)到這顆恒星前面時(shí),使得恒星的光變暗。C選項(xiàng):這顆恒星會(huì)阻擋我們的視線,使我們看不到新星,這個(gè)推斷是正確的。答案為C.

(2)

其中的D選項(xiàng)與上題觀點(diǎn)一致,也就是用來發(fā)現(xiàn)新星。答案為D.

(3)

這道題考查考生概括文章主旨大意的能力。對(duì)于這類題,最好的方法就是用假設(shè)的方法去判斷,因?yàn)闃?biāo)題應(yīng)該在最大程度上覆蓋全文。此篇文章主要圍繞這顆新星的發(fā)現(xiàn)展開。答案為B.

    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.
