2、e proper form of the given word; for the other blanks,use one word that best fits each blank.Its time to go out for a run!As little as five minutes of running or jogging each day can help people reduce their risk of premature death by nearly one-third and extend their lives by about three years, acc
3、ording to a U.S. study.The researchers tracked the exercise habits of over 55,000 adults in the United States for six to twenty-two years. About 24 percent of the adults described themselves (21)_ runners. Compared to those who didnt run, those who did were 30 percent (22)_(likely) to die of any cau
4、se during the course of the study. These figures (23)_(adjust) to take into account peoples smoking and drinking habits, how old they were (24)_ they enrolled in the study, their familys health history and their other exercise habits.The researchers divided up the roughly 13,000 runners into five gr
5、oups (25)_(base) on how many minutes they ran per week. Those (26)_ were in the lowest group ran up to 50 minutes over a seven-day period, and those in the highest group ran for more than 175 minutes over the course of a week. According to the study, the benefits of running were pretty much the same
6、 for all runners.“Running even at lower doses or slower speeds was associated with significant benefits,” the researchers wrote in their report. (27)_(reduce) the risk of premature death, they calculated, all it took was 30 to 59 minutes of running per week.“This finding has clinical and public heal
7、th importance,” the report continues. “Time is one of the strongest barriers to (28)_(participate) in physical activity. This study may motivate more people to start running. People who (29)_ hardly devote 20 minutes to moderate physical activity each day may appreciate the efficiency of a five-minu

Each word can only be used once. Note that there is one word more than you need. In the wake of the historic ann
9、ouncement of the discovery of gravitational waves on February 11, 2016 by the Laser Interferometer Gravitational-Wave Observatory (LIGO), British physicist and black hole theorist Stephen Hawking was quick to 31the US-led collaboration, sharing his excitement for the historic news. According to Hawk
10、ing, these results confirm several very important 32of Einsteins theory of general relativity and it also confirms the existence of gravitational waves directly.As is becoming clear, the direct detection of these ripples in space time not only confirms Einsteins famous theory of general theory but i
11、t also opens our eyes to a(n) 33“dark” universe. Astronomers employ the electromagnetic spectrum (电磁光谱) to study the universe, but objects that do not radiate in the electromagnetic spectrum will go 34. But now we know how to detect gravitational waves, which can help us detect and study some of the
12、 most energetic cosmic phenomena. “Gravitational waves provide a completely new way of looking at the universe and the ability to detect them has the 35to revolutionize astronomy” said Hawking. “The discovery is the first observation of black holes merging. The observed 36of this system are consiste
13、nt with predictions about black holes that I made in 1970 in Cambridge.” However, this discovery also presents a puzzle for astrophysicists. The mass of each of the black holes are larger than expected for those formed by the gravitational 37of a star-so how did both of these black holes become so m
14、assiveThis question touches on one of the biggest mysterious 38black hole evolution. Currently, astronomers are having a hard time understanding how black holes grow to be so massive. On the one end of the scale, there are “stellar mass(恒星质量)” black holes that form immediately after a massive star e
15、xplodes, 39an extremely bright light. And we also have an abundance of evidence for the existence of the super-massive that live in the centers of most galaxies. There should be evidence of black holes of all sizes, but “intermediate mass” black holes and black holes of a few dozen solar masses are 40rare, throwing some black holes evolution theories into doubt. One thing is clear, however. This is the first time that weve acquired direct evidence of a black hole merger. So its good to know were on the right track.III.
