6、 DNA template strand. Scientists have tried for years to make TdT add one nucleotide at a time and stop, before repeating the process with a different nucleotide. But TdT doesnt work wel1 with these modified nucleotides. TdT is very picky. says Sebastian Pal luk, a Ph. I）, student. One such system,
7、for example, required about an hour to add each modified base, far too slow to be practical.Ultimately, the approach should be cheap, because TdT is easy to manufacture in bacteria. It, s also fast. Most new nucleotides attach to the growing oligo in 10 to 20 seconds. For now, the step still takes a
8、 minute. So synthesizing a whole gene will still likely take the better part of a day.The new approach is not quite ready. So far, the group has made oligos only 10 bases long. And there are still a few writing problems, as the approach was only 98% accurate at writing DNA, below the 99% accuracy of

12、了科学家们正在尝试用一个最新的方法来改写基因，如果成功, 将可以在一天的时间里创造出一个新的基因，但FI前该技术尚未成熟。【12题详解】细节理解题。由第二段最后一句话But the process is typically s 1 ow and error-prone, limiting oligos to about 200 letters-a tiny part of the thousands of letters that make up most genes.（但这个过程通常是缓慢而且容易出错的，限制寡核仔酸只有大约200个字母一一这只是组成大多数基因 的数千个字母中的一小部分。）”
13、可知传统重组基因方法的缺点是缓慢且容易出错，故选I）。【13题详解】细节理解题。根据第二段的第一句话“Over the decades, most researchers have settled on one particular polymerase（聚合酶），called TdT, because unlike others, it can attach new nucleotides to an oligo strand without following a DNA template strand.（在过去的几十年里，大多数研究人员 都专注于一种特殊的聚合酹，称为TdT,因为与其他酹

23、的全新一面。文章主要介绍了做事高效的人的几个日常习惯。【16题详解】根据上文 “When i t comes to being more efficient at your job. you know the basics. But research shows a whole new side of productivity you may not have realized.（当你在工作中更有效率的时候, 你知道基本原理。但研究表明，你可能还没有意识到生产率的全新一面）”结合后文主要说明了几个有助于 高效的好习惯，可知E选项“看看这些天生高效的人所具有的习惯”符合语境，起到了总起下文的作用
24、。 故选E。【17题详解】根据小标题“Focus on being happier.（专注于变得更快乐）”以及后文“Even if a low mood does not completely disab 1e you from functioning, it can decrease your productivity to make you far less efficient. Also, don* t hesitate to seek help. This will not only help you achieve a more stable work-life balance, b
25、ut a new outlook can also open you up to new opportunities and necessary changes.（即使低落的情绪不会让你完全丧失工作能力，它也会降低你的生产力，使你的效率大大降低。 此外，不要犹豫寻求帮助。这不仅会帮助你实现更稳定的工作和生活的平衡，而且一个新的前景也可以为 你打开新的机会和必要的改变）”可知，后文提到情绪低落会使效率降低，可推知反过来快乐的人工作效率 更高，且I）选项中happier与标题中happier相对应。故I）选项“研究发现快乐的人工作效率更高”符合 语境，故选D。【18题详解】根据上文“You kno
26、w the countless benefits of exercise.（你知道运动有无数好处）”以及后文“Even 30- minute bursts of moderate-to-high physical activity just three to four times a day can go a long way in helping you accomplish your personal and professional goals.

27、lf motivated.（即使每天进行三到四次 30 分钟中等强 度到高强度的运动，也会对你实现个人和职业目标大有帮助。如果你对健身房不感兴趣，那就参加集体健 身课，让自己保持动力）”可知，上文讲锻炼的好处，下文举具体例子，由此推知，本句承接上文说明锻炼 的好处，F项中的It指代前句的exerciseo故F选项“它能改善你的情绪，提高你的大脑的生产力”符合语境，故选L【19题详解】设空处为本段小标题。根据本段内容 Pressing pause is important. Studies show that prolonged tasks that require high levels of
28、 focus, energy, and attention can cause you to become less productive and focused over time. Take brief mental breaks.

29、nds to deteriorate.（按下暂停键很重要。研究表明，需要高度 专注、精力和注意力的长时间任务会导致你的效率和注意力下降,进行短暂的精神休息。相比之下，当我 们进行“健康休息”时，我们会更专注于下一个工作。当我们试图不间断地持续工作在一个项目上时，我 们的工作质量往往会恶化）”可知，本段讲有的工作需要全身心地投入，会很累，如果不间断地工作下去， 效率会很低，这时需要我们身心都需要休息，且后文中Take brief mental breaks.与A选项中Take breaks 相对应。故A选项“偶尔休息”符合语境，可作为本段小标题。故选A。【20题详解】根据上文“People be
30、lieve the more we can do at once, the better.（人们相信我们一次做的越多越 好）” 以及后文 “In fact, the more we multitask, the less efficient and productive we become. Instead, to increase productivity, focus on one task at a time until its completed and then give all of your attention to the next task.（事实上,我们一心多用的次数越多,
31、我们的效率和生产力就越低。 相反，为了提高效率，一次只专注于一项任务，直到它完成，然后把所有的注意力放在下一项任务.匕”可 知，上文提到人们认为同时做越多事越好，后文则说同时做很多事效率和创造力都降低了，可知前后为转 折关系，说明情况正好相反，人们不应该一次性做很多事情。故C选项“然而，研究显示相反的结果”符 合语境，故选C。第三部分语言知识运用（共两节，满分30分）第一节完形填空（共15小题；每小题1分，满分15分）阅读下面短文，从短文后各题所给的A、B、C和 D四个选项中，选出可以填入最佳选项。A woman was drowning and she put her hand in the
