A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops（笔记本电脑）.
Students are increasingly using laptops for note-taking because of speed and legibility（清晰度）. But the research has found laptop users are less able to remember and apply the concepts they have been taught.
Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes “mindlessly” by taking down word for word what the professors said.
In the first experiment, students were given either a laptop or pen and paper. They listened to the same lectures and were told to use their usual note-taking skills. Thirty minutes after the talk, they were examined on their ability to remember facts and on how well they understood concepts.
The researchers found that laptop users took twice as many notes as those who wrote by hand. However, the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts.
The researchers’ report said, “While more notes arc beneficial, if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears.”
In another experiment aimed at testing long-term memory, students took notes as before but were tested a week after the lecture. This time, the students who wrote notes by hand performed significantly better on the exam.
These two experiments suggest that handwritten notes arc not only better for immediate learning and understanding, but that they also lead to superior revision in the future.

【考点】考察科普知识类阅读
【文章大意】作者在本文中讲述了一次实验:使用笔记本电脑记笔记和手动记笔记的学生进行对比。结果发现手动记笔记的学生表现更好，告诉我们需要进行手动记笔记，而不是使用电脑。
21.【答案】A
【试题解析】细节题。根据文章第二段第一句Students are increasingly using laptops for note-taking because of speed and legibility（清晰度）.可知学生越来越多使用电脑记笔记是因为速度和清晰度。也就是说使用笔记本电脑记笔记速度更快，可以记录更多的内容。故A正确。
22. 【答案】B
【试题解析】推理题。根据第三段Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes “mindlessly” by taking down word for word what the professors said. 研究人们做实验是为了发现使用笔记本电脑记笔记是否会让人处于一种无意识的状态之中，只是机械地输入。而实验结果说明用笔记本记录的学生表现不如使用钢笔记录的人。说明使用笔记本记录的确会让人有mindless的感觉。故B正确。
23. 【答案】B
【试题解析】推理题。根据文章最后一段These two experiments suggest that handwritten notes arc not only better for immediate learning and understanding, but that they also lead to superior revision in the future.可知手动记笔记对于短期长期记忆都有好处，也就说本文强调我们需要进行手动记笔记，而不是使用电脑。故B正确。
24. 【答案】C
【试题解析】推理题。本文通过讲述一个实验结论告诉我们手动记笔记对于短期长期记忆都有好处，学生的表现比使用电脑记笔记更好。不会是广告，电脑教科书也不会是金融报告，这属于教学类的科学研究。故C正确。
【长难句解析】
1.A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops。
【翻译】一项新的研究显示上课时手动写笔记的学生在考试中要比使用笔记本电脑的学生表现更好。
【分析】本句中动词show后面宾语从句的引导词that被省略了，这个宾语从句中含有定语从句who write notes by hand during lectures修饰students；另外一个定语从句who use laptops修饰those。
2.These two experiments suggest that handwritten notes are not only better for immediate learning and understanding, but that they also lead to superior revision in the future.
【翻译】这两个使用都说明手动写笔记不仅对于即时学习和理解有好处，而且会导致未来的表现更好。
【分析】本句中的动词suggest表示“说明，暗示”，并不是“建议”；另外句中的宾语从句that handwritten notes are not only better for immediate learning and understanding, but that they also lead to superior revision in the future.较长，谓语部分是有not only…but also…连接。
