城镇化进程有三个阶段：初始阶段是城镇人口占总人口的比重 在30%以下；中期阶段是城镇人口占总人口的比重为30%一70%； 后期阶段是城镇人口占总人口的比重在70%以上。截至2019年，上 海常住人口城镇化率最高，达到88.10%；江西常住人口城镇化率为 57.4%;西藏常住人口城镇化率最低，仅有31.50%。读 2015一2019年我国常住人口城镇化率(%)统计图，完成12~13题。 62 61 60.60 0 59.58 59 58.52 58 57.35 765 56.10 2015 2016 2017 2018 2019年份 12.我国目前城市化进程仍处在 A.初始阶段B.中期阶段C.后期阶段D.无法判断

the screens of stopwatches,they once again saw a skewed num ber. Faux says that the obvious solution is for stopwatches to have large data tables for transforming the numbers of oscilla- tions into the time in seconds,rather than using an algorithm. The researchers now hope to investigate whether the errors are found at large sporting events. New Scientist asked the International Olympic Committee if timing at the Olympic Games could be affected by this phenome non.The IOC passed the request for comment to Omega,the of- ficial timekeeper of the Games,which didn't respond.

第二部分阅读理解（共4小题；每小题7.5分，满分30分） 阅读下面短文，从每题所给的A、B、C和D四个选项中，选出 最佳选项。 Digital stopwatches can make rounding(四舍五入的) errors of up to 0.11 seconds,which could be enough to change the win ner of close races.Although the devices record time extremely accurately,they often make errors when changing that raw data to human-readable numbers. Most digital stopwatches measure time by counting the pre- dictable oscillations (of a quartz crystal.The crystal will pulse many thousands of times a second and the final count is transformed into seconds in a format known as a floating-point representation that is commonly used by digital devices.

good introduction to the course,and it will probably cover a lot of useful information about the upcoming semester. W:Maybe you're right.It's just that I hate being in large groups.I'm not going to know anyone there. M:You'll know me,though.Besides,I think it will be a good chance to meet people,and there will probably be times when we will have to work together in groups. W:Our course outline seems to have all the information we need. I can't see there is anything new to discuss. M:I heard there will be a former graduate there to provide details about what kind of job opportunities are out there after we graduate.It could be more helpful than you think. W:I don't know.

W:Well,I've got something quite different from that this time. No singing at all.Though it's got some great music,it's an adventure in space.I'm sure you'll enjoy that more than a comedy we saw last time. M:Great!Let's watch that then. (Text 7) W:Happy New Year！ M:Happy New Year!Kate,do you have any wishes for the new year? W:Of course.I hope I can get a good score in the college en- trance examination in June this year,and I can visit Beijing during the summer holiday. M:Which is the most important?
