Five ways to end procrastination

Never put off till tomorrow what may be done today. Waiting until later is one of life’s guilty secrets, but procrastination (拖延症) is linked to poorer health, work and relationship outcomes. Here are five ways to try to remedy (纠正) procrastination.:

1. A five-minute start

Five minutes is nothing it’s just three hundred seconds. It’s the length of a song or a TV commercial. Pick up a project you’ve been putting off and spare just 300 seconds of your time to do it. 1 After a while, the momentum (动力) of beginning the task will push you forward.

2. Set goals and rewards

During the day, set goals and rewards. Each time you achieve a goal, you earn the reward: a short break, a funny YouTube video or something else. 2 Make sure you select a time to review your progress and adjust your targets accordingly.

3. Be good to yourself me today versus me tomorrow

Sometimes, when you find yourself buried in work, you are upset with yourself for not having started earlier. Imagine a conversation, between “you today” and “you tomorrow”. 3

4. I was there witnessing accountability (责任制)

4 Consider going on a diet: Is there more pressure if you don’t tell a soul, or if you announce it to all your friends, with strict rules to follow if you are invited to dinner? It seems an obvious way of making you feel guilty, but it can also be highly effective.

5. Set creative punishments negative consequences

Make the consequences of inaction so unbearable that you have no choice but to get busy now. You could write a note to someone that you don’t like. Give the note to a friend with strict instructions to mail the note if you do not achieve your goal. The more you dislike the other party, the stronger the motivation to get the task done.

Procrastination is a silent killer of dreams. 5 By understanding and fixing your procrastination, you’ll discover you jump-start many areas of your life.

A. Everyone suffers from it.

B. Once the five minutes is up, stop and reassess.

C. Everyone likes to have a dream of procrastination.

D. Going public with a goal increases your support and accountability.

E. What is the future of my life with the intention of putting off my tasks?

F. If “you tomorrow” could chat with “you today” what would he say?

G. It’s important that the goals are realistic and the rewards are in proportion (按比例).

【题目】根据材料并结合所学知识回答问题。

材料一 在中国古代,天文和历法一直受到高度重视,天文学家和君主有着密切的关系,他们是官方政府机构不可或缺的人员。至公元1851年,历代政权颁行了100余部历法,《夏小正》是中国最古老的历书,形成于公元前5世纪左右,包含了许多关于气候、星象及物候方面的叙述,按一年十二个月的顺序排列。古代的历法,现在名为“农历”或“阴历”,仍决定人们欢度“春节”以及“中秋”、“端午”等节日的具体日期。

天象观测有助于制定更为准确的历法。古代史书中有着连续的有关日食、月食与星象变化的记录,并从政治角度解释这些现象。史书明确记录了公元前186年吕后当政时发生了一次日食,但现代天文学研究表明,所记日食绝不可能发生。日食记录居然因政治上的原因而有所增减:统治者残暴,记载的日食现象就多;统治者开明,日食便很少发生。

材料二 宋应星15871666青年时曾考取举人,后来连续六次赴京参加进士考试,均名落孙山。45岁以后,面对明末流民遍地的现实,宋应星不再追求科举功名,转而探求致富之术。他全面搜集整理传统农业、手工业技术,撰成《天工开物》一书,书名取天工人其代之”“开物成务之义。正如宋应星在该书的序言中所说,是书与科举功名毫无关系,当时士大夫对这部书不屑一顾。后来乾隆时编《四库全书》,不予收录,民间因此更不敢印行。这部书在19世纪传入欧洲后,被誉为17世纪中国科技的百科全书,是我们今天探讨古代科技成就的重要文献。

——摘编自《宋应星评传》等

1根据材料并结合所学知识,概括指出中国古代重视天文历法的表现。

2根据材料二所学知识,指出宋应星科技成果的特点及该成果出现的背景。

3根据材料并结合所学知识,分析古代科技在明清时期转为落后的原因。
