Current gym dogma holds that to build muscle size you need to lift heavy weights. (1) , a new study (2) at McMaster University has shown that a similar degree of muscle building can be achieved by using lighter weights. The secret is to pump air (3) you reach muscle fatigue. The (4) are published in PLoS ONE. " (5) grunting and straining to lift heavy weights, you can (6) something much lighter but you have to lift it until you can't lift it (7) ," says Stuart Phillips, associate professor of kinesiology at McMaster University. "We're convinced that (8) muscle means (9) your muscle to make new muscle proteins, a process in the body that over time (10) into bigger muscles. " Phillips praised lead author and senior Ph.D. student Nicholas Burd for masterminding the project that showed it's really not the weight that you lift but the fact that you get muscular fatigue that's the (11) point in building muscle. The study used light weights that (12) a percentage of what the (13) could lift. The heavier weights were set (14) 90% of a person's best lift and the light weights at a mere 30%o of what people could lift. "It's a very light weight," says Phillips noting that the 80% 90% (15) is usually something people can lift from 5~10 times before fatigue sets in. At 30%, Burd reported that subjects could lift that weight at least 24 times (16) they felt fatigue. "We're (17) to see where this new paradigm will lead," says Phillips, adding that these new data have (18) significance for gym enthusiasts but more importantly for people with compromised skeletal muscle mass, (19) the elderly, patients with cancer, or those who are (20) from trauma, surgery or even stroke.
单选题
A. maintained B. observed C. conducted D. carried
【正确答案】
C
【答案解析】[解析] 该空白处所填的词应该与前面的study(研究)相搭配,正确答案为C项conducted“进行;带领”。conduct a study意为“进行一项研究”。A项maintained“维持,维护”,不与study搭配,maintain多指继续及维持前文已经提到的事情;B项observed“观察;遵守”,也不与study搭配;“研究”强调的是操作性和实验性,而不是观察;carry若要表达“实施,进行”的意思应该与介词out搭配,即carry out。
单选题
A. Rather than B. In addition C. Instead D. Not only
【正确答案】
A
【答案解析】[解析] 本题考查上下文语意连贯。考生要比较第三段第一句中逗号前后两个分句的关系,这里要强调新的研究成果,即“利用较轻的器材进行训练也可以达到锻炼肌肉的效果”,因此前半句“grunting and straining to lift heavy weights”(气喘吁吁且容易受伤地举重物)就不应该是最可取的方案,故空白处应该选A项Rather than“而不是……”;B项In addition表示“除……以外(还)”;C项Instead“代替,反而”,选项缺少of,instead of(sth./sb.)可以表示与rather than一样的意思;D项Not only指的是“不仅仅”,不符合句意。
【答案解析】[解析] 前面已经出现“it's really not the weight that…”,意味着重点在后面,要选一个形容词与point组合表示“关键要素”的含义。A项certain表示“某一,确信的”;C项whole表示“整体的”;D项plus作形容词时表示“附加的”;只有B项critical“关键的”与句意吻合。
