　　2. NASA tried to retract the P6 solar array by remote control on Wednesday.

　　3. The P6 array will be fully retracted from the space back to the earth.

　　4. Bay 17.5 is the segment of the P6 array which caused the fold failure by failing to slide into the box.

　　5. A fourth spacewalk will be aimed to guide the P6 solar array into the box.

　　6. NASA has found the cause of the retraction failure and knows how to prevent it.

　　7. The ISS at present is too short of electrical power to run laboratories.

　　Questions 8-9

　　Write your answers in boxes 8-9 on your answer sheet.

　　

　　8. ……would be send to P6 to accomplish the retraction of one of its solar arrays.

　　9. ……is the lead flight director of Discovery， the space shuttle.

　　Question 10

　　Choose TWO correct letters A-D and Write them in box 10 on your answer sheet.

　　10. Astronauts in the ISS were asked to protect themselves from？o：p>

　　A. increased solar activity.

　　B.     increased solar energy.

　　C.     possible radiation.

　　D.     danger caused by satellites.

　　Questions 11-14

　　Complete the notes below.

　　Choose one suitable number from Reading Passage 1 for each answer.

　　Write your answers in boxes 11-14 on your answer sheet.

　　The P6 solar array was installed……11……years ago. NASA decided to retract it in order that a newer P4 solar array installed in……12……can rotate to track the Sun without colliding with it. On Wednesday an attempt to retract the solar array partly failed owing to that only 13 and a half of the array's ……13…… segments were safely folded. Despite the failure， the array had been pulled back and the space between it and P4 at their closest points is ……14…… metres， which is far enough to avoid the collision between them.

　　Key and Explanations：

　　1. FALSE

　　See Paragraph 2 under the subtitle "Fold failure"： Thursday's spacewalk to tackle other jobs will proceed as planned， without a fix to the solar array.

　　2. TRUE

　　See Paragraph 4 under the subtitle "Fold failure"： After almost 6.5 hours of trying to get the array to retract and more than 40 remote-control commands sent to the array……

　　3. FALSE

　　See Paragraph 5 under the subtitle "Fold failure"： NASA wants to get the P6 array fully retracted before they move it to another part of the station on a future mission.

　　4. TRUE

　　See the third paragraph under the subtitle "Pile up"： Wednesday's showstopper was caused by one segment in particular， known as bay 17.5. It would not slide into the box……

　　5. TRUE

　　See the first paragraph under the subtitle “Reconfiguration”： A fourth spacewalk？sending astronauts？to help guide the array into the box.

　　6. FALSE

　　See the fourth paragraph under the subtitle “Reconfiguration”： ……managers are eager to learn the cause of the problem and how to prevent it in the future.

　　7. NOT GIVEN

　　See the first paragraph under the subtitle “Solar flares”： …they will help rewire the ISS so that the station will have enough electrical power to add energy-intensive components， such as future laboratories.

　　8. Christer Fuglesang and Bob Curbeam

　　See the second paragraph under the subtitle “Reconfiguration”：  Astronauts Bob Curbeam and Christer Fuglesang would be the crew members asked to make the spacewalk.

　　9. John Curry

　　See Paragraph 2 under the subtitle“Fold failure”： says John Curry， Discovery's lead flight director.

　　10. A & C

　　See the last paragraph： ……flight surgeons have asked the crews to sleep in areas of the shuttle and station with additional shielding to protect them from increased solar activity and the possibility of extra radiation heading their way.

　　11. 6

　　See Paragraph 1 under the subtitle “Fold failure”： The retraction of a six-year-old solar array on the International Space Station （ISS） did not go to plan on Wednesday.

　　12. 2006

　　See the third to the last paragraph： The newer arrays， part of the P4 element， were installed in 2006……

　　13. 31

　　See Paragraph 4 under the subtitle “Fold failure”： only 13 and a half of the array's 31 segments were safely folded in the box.

　　14. 5

　　See Paragraph 5 under the subtitle “Fold failure”： There are five metres of space between the two arrays at their closest points.
