A recent study shows that people can remember maths better if they learn it before bedtime. Many people think it's better to study when your mind is fresh in the morning, but scientists in the UK said that a good night's sleep helps the words or numbers stick in your brain.
The study asked 184 people in the UK, aged 18 to 40, to learn multiplication problems by heart. The problems required multiplying numbers from 22 to 33 by 6, 7, 8, and 9—for example, 25 times (乘以) 8. The researchers wanted to test how quickly each person could remember the answers.
The volunteers first had to learn the answers before bed, between 8:00 pm and 10:45 pm, and they were tested the next morning. A week later, they were asked to learn answers when they woke up, between 7:30 am and 10:00 am. They were tested at the end of the day.
In both experiments, the volunteers had about 10 hours between learning the problems and taking the tests. The people who learned multiplication problems before bed remembered them better, scoring an average of 20.7. The morning learners scored 18.5.
This study shows that the mind soaks up numbers when we're asleep.

答案
【主旨大意】本文讲述了一项关于学习数学的研究，研究发现晚上睡前学习数学，有助于更好地记住数学内容。
1 A 【点拨】推理判断题。根据第二段中“The study asked 184 people in the UK, aged 18 to 40”可知，研究的对象是英国18到40岁的人群，故选A。
2 B 【点拨】细节理解题。根据第一段中“A recent study shows that people can remember maths better if they learn it before bedtime.”和最后一段“This study shows that the mind soaks up numbers when we're asleep.”可知，睡前学习数学有助于我们学习，故选B。
3 A 【点拨】词义猜测题。根据“the mind soaks up numbers when we're asleep”以及上文可知，大脑在我们睡觉时会更好地记住数字，因此“soaks up”表示“吸收”，对应“takes in”。故选A。

解析
【分析】
本题为英语阅读理解题，包含3道小题，分别考查推理判断、细节理解、词义猜测能力。解题思路：先通读全文把握主旨，再针对每道题的题干关键词，回到原文定位对应信息，逐一分析选项，排除不符合原文的错误选项，最终确定正确答案。
【解析】
1. 第1题：题干询问研究的志愿者身份，根据原文第二段“The study asked 184 people in the UK, aged 18 to 40”可知，志愿者是英国18-40岁的人群。A选项“19岁英国人”符合该范围；B选项年龄10岁、C选项国籍美国、D选项年龄45岁均不符合，故选A。
2. 第2题：题干询问从文章可获取的信息，根据第一段“people can remember maths better if they learn it before bedtime”及最后一段“the mind soaks up numbers when we're asleep”可知，睡前学习数学有助于记忆。A选项“早上学习更好”与原文相悖；C选项“研究讲如何做乘法”并非研究内容；D选项“测试在7:30-10:00”是早上学习的时间，并非测试时间，故选B。
3. 第3题：题干猜测“soaks up”的含义，结合上下文，研究表明睡前学习数学记忆更好，大脑在睡眠时会更好地处理数字，故“soaks up”意为“吸收”。A选项“takes in”（吸收）符合；B选项“turns in”（上交）、C选项“puts up”（张贴）、D选项“cleans up”（打扫）均不符合，故选A。
【答案】
1.A 2.B 3.A
【知识点】
英语阅读理解、推理判断、词义猜测
【点评】
本文是一篇关于学习数学的科普类英语阅读，考查学生对文章细节的查找、推理判断及词义猜测能力，整体难度适中，需学生仔细定位原文信息即可解答。
【难度系数】
0.7
