In 2010,the planetary(行星的）defence team at NASA had identified and logged 90 percent of the asteroids(小行星）near Earth measuring 1km wide. These\size of mountains and include anything within 50 million kilometers of Earth's orbit.With an estimated 50 left to log, NASA says none of the 887 it knows about are a significant danger to the planet.
Now NASA is working towards logging some of the smaller asteroids,those measuring 140 metres wide or more. Of the 25, 000 estimated asteroids of this size,so far about 8, 000 have been logged, leaving 17, 000 unaccounted for. Considering that a 19-metre asteroid that exploded above the city of Chelyabinsk in Russia in 2013 injured 1, 200 people,these middle sized asteroids would be a serious danger if they enter Earth's orbit. ①
Whether NASA can find the remaining middle-sized NEOs depends on getting the money to build NEOCam,a 0. 5-metre space telescope which would use infrared(红外线的）light to locate asteroids. ② Once logged,the planetary defence team would still need to work out how to defend the planet against being hit by the truly worrying asteroids-the PHAs.
＂Potentially Hazardous Asteroids\kilometres of Earth's orbit. NASA has created a map of 1, 400 PHAs,none of which are expected to be a threat in the next one hundred years. _③ With technology already available,NASA can track these objects and make predictions about possible impact,at which point two defence solutions could be launched.
The first is DART-the Double Asteroid Redirection Test. Plans are scheduled to test DART on the moon of an asteroid called Didymos. \and hopefully the impact of DART will knock it out of its orbit enough for Earth-based telescopes to pick up.
Another suggested defence against a PHA on course to hit Earth is to blow it up using a nuclear weapon. It may sound like a plot from a film, and it was the subject of the 1998 film Armageddon, but the Hypervelocity Asteroid Mitigation Mission for Emergency Response (HAMMER) is a genuine NASA proposal. ④ The eight-ton rockets would be fired at an approaching asteroid with the hope 9
of bumping it off course. If the asteroid was too close to Earth for this plan to work, the rockets would carry nuclear bombs to blow it up instead.
61. Which of the following has the closest meaning to the underlined word“log”? A record B protect C decide D. discover 62. What can we know from the first two paragraphs? A. NASA has measured 90 percent of the asteroids B. The asteroids are proved to be no danger to the planet C. There are still many unlogged asteroids near Earth. D. Middle-sized asteroids are more likely to enter Earth's orbit 63. What can we infer from the passage?
A. PHAs are a big concern but not an immediate threat in the short term B People needn't worry about the middle-sized asteroids with the help of DART. C. A special telescope will provide a complete defence against asteroids hitting Earth D. It is likely that Didymoon will be knocked out of its orbit, dropping to Earth 64. Where does the following sentence fit best in the passage? \” A.① B ② C ③ D.④

Monday dawned warm and rainless. Aurelio Escovar, a dentist without a degree, opened his office at six. When he had a handful of instruments arranged on the table, he sat down to polish the false teeth. He seemed not to be thinking about what he was doing, but worked steadily
The sharp voice of his eleven-year-old son interrupted his concentration “Papa” “What?”
“The Mayor wants to know if you'll pull his tooth” “Tell him I’m not here.”
