I 2 (be) into sports since I was six years old. I have known many 3 (coach) and heard hundreds of their tips, but they usually 4 (focus) on drills (训练) to develop my skills and reach the next level of play. When I was in Senior Two, I met the new school basketball coach, Brian Pawlowski. I thought I was certain to 5 (select) for the school team since I had been in it the year before. I showed up to the tryouts (选拔赛) and put out about 90% effort since I thought I’d make 6 with no problem. That was a big mistake. Brian Pawlowski is the 7 ( strict) coach I have ever met. He didn't expect 100% effort, but he expected 200 effort. Some think this is crazy, 8 it isn’t. After training, as we were getting a cup of cold water to drink, I said,“Mr Pawlowski, your lesson was the best I ever had." I was 9 (complete) sincere. He expects us to be excellent 10 just on the court but in the classroom. If I am not working on basketball, I am reading a book that he thinks will help us better understand life's challenges. 【答案】 1.who/that 2.have been 3.coaches 4.focus 5.be selected 6.it 7.strictest 8.but 9.completely 10.not 1.who/that（关系代词）此处考查定语从句。先行词是 “my mother”，指人，且从句中缺少主语，需用关系代词 “who” 或 “that” 引导定语从句，修饰 “mother”，说明 “抚养我长大的母亲”。 2.have been（现在完成时）句中出现时间状语 “since I was six years old”（自从我六岁起），这是现在完成时的标志性时间状语，强调动作从过去持续到现在。主语是第一人称 “I”，故用 “have been”，“be into” 表示 “热衷于、沉迷于”，此处指 “我从六岁起就热衷于体育运动”。 3.coaches（可数名词复数）“many” 后接可数名词复数形式，“coach”（教练）的复数变化规则为：以 “ch” 结尾的名词，变复数时加 “es”，故填 “coaches”，表示 “我认识很多教练”。 4.focus（一般现在时）此处描述的是教练们通常的做法，属于 “经常性、习惯性的动作”，需用一般现在时。主语 “they” 是复数，谓语动词用原形 “focus”，“focus on” 为固定搭配，意为 “专注于、聚焦于”。 5.be selected（被动语态）主语 “I” 与动词 “select”（选拔）之间是被动关系 ——“我被选拔进球队”，且 “be certain to do sth”（肯定会做某事）是固定结构，to 后接动词原形，故此处用被动语态 “be selected”。 6.it（代词）“make it” 是固定短语，意为 “成功做到、达成目标”，此处指 “我认为自己能毫无问题地入选球队”，用 “it” 指代 “入选球队” 这件事。 7.strictest（形容词最高级）句中出现范围限定词 “I have ever met”（我曾经遇到过的），表示三者及以上的比较，需用形容词最高级。“strict”（严格的）的最高级是 “strictest”，意为 “Brian Pawlowski 是我见过的最严格的教练”。 8.but（转折连词）前半句 “Some think this is crazy”（有些人认为这很疯狂）与后半句 “it isn’t”（其实并不疯狂）之间是转折关系，需用转折连词 “but” 连接，体现逻辑上的对比。 9.completely（副词）此处需用副词修饰形容词 “sincere”（真诚的），“complete”（形容词，完全的）的副词形式是 “completely”，表示 “我非常真诚地说”。 10.not（固定搭配）“not just...but...” 是固定结构，意为 “不仅…… 而且……”，此处指 “他期望我们不仅在球场上表现出色，在课堂上也要优秀”，故填 “not”。 六、阅读理解 For those who can stomach it,working out before breakfast may be more beneficial for health than eating first,according to a study of meal timing and physical activity. Athletes and scientists have long known that meal timing affects performance.However,far less has been known about how meal timing and exercise might affect general health. To find out,British scientists conducted a study.They first found 10 overweight and inactive but otherwise healthy young men,whose lifestyles are,for better and worse,representative of those of most of us.They tested the men’s fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue. Then,on two separate morning visits to the scientists’ lab,each man walked for an hour at an average speed that,in theory,should allow his body to rely mainly on fat for fuel.Before one of these workouts,the men skipped breakfast,meaning that they exercised on a completely empty stomach after a long overnight fast (禁食).On the other occasion,they ate a rich morning meal about two hours before they started walking. Just before and an hour after each workout,the scientists took additional samples of the men’s blood and fat tissue. Then they compared the samples.There were considerable differences.Most obviously,the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten.As a result,they burned more fat during walks on an empty stomach than when they had eaten first.On the other hand,they burned slightly more calories (卡路里),on average,during the workout after breakfast than after fasting. But it was the effects deep within the fat cells that may have been the most significant,the researchers found.Multiple genes behaved differently,depending on whether someone had eaten or not before walking.Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin (胰岛素) levels throughout the body and so are associated with improved metabolic health.These genes were much more active when the men had fasted before exercise than when they had breakfasted. The implication of these results is that to gain the greatest health benefits from exercise,it may be wise to skip eating first. 1.The underlined expression “stomach it” in paragraph 1 most probably means “　　　”. A.digest the meal easily B.manage without breakfast C.decide wisely what to eat D.eat whatever is offered 2.Why were the 10 people chosen for the experiment? A.Their lifestyles were typical of ordinary people. B.Their lack of exercise led to overweight. C.They could walk at an average speed. D.They had slow metabolic rates. 3.What happened to those who ate breakfast before exercise? A.They successfully lost weight. B.They consumed a bit more calories. C.They burned more fat on average. D.They displayed higher insulin levels. 4.What could be learned from the research? A.A workout after breakfast improves gene performances. B.Too much workout often slows metabolic rates. C.Lifestyle is not as important as morning exercise. D.Physical exercise before breakfast is better for health. 【答案】1-4.
