Question

    For some students, getting better grades can seem like an impossible task sometimes. With the challenges（挑战）of school, just paying attention in class or studying hard isn’t always enough. But what if there were other ways for students to improve their grades? For parents and students who have ever wondered if this is possible, now you can rest easy. Research suggests that a person who likes doing activities can improve their grades.

Scientists think that those students who are active are not just exercising their bodies, but also exercising their brains（大脑）. In turn, they can be able to improve their grades at school.

In the most recent study, researchers found that when children played for half an hour each day, they were better at organizing（组织）their schoolwork as well as doing project work and learning traditionally “difficult” subjects, such as maths.

What does this mean for children who aren’t active? Researchers think that if kids don’t get enough activities, they are going to be at a disadvantage when it comes to school performance.

In the research experiment, a group of children skipped with ropes（跳绳）, played basketball and did a number of other games or exercises. Another group of children didn’t do any activities. They took part in testing both before experiment and after the experiment. Testing was mainly for maths and reading skills. Results showed that the children in the activity group did better on the tests than those who had no activity.

All work and no play will not only make Jack a dull（迟钝的）boy, but will also negatively（消极地）affect his grades in school, according to a new study published in the Journal of Pediatrics.

Parents complain（抱怨）children today are actually less active and they always worry about their grades. Dr. Belton, an expert, said,“If you’d like to see your kids do better in school, have them close their books, set down their pencils and go outside to play.”

【解析】

本篇文章作者通过正反两个方面，论证了户外活动对人的好处，提出一个喜欢做活动的人可以提高他们成绩的观点。

1.

词义猜测题。Stop worrying.停止担心；Keep working.继续工作；Continue learning.继续学习；Study hard.努力学习。根据上一句“But what if there were other ways for students to improve their grades? 但是如果有其他方法可以让学生提高成绩呢?”，及下一句“Research suggests that a person who likes doing activities can improve their grades. 研究表明，喜欢活动的人可以提高成绩。”，可知划线部分词语的意思应该是“不要再担心了”，故选A。

2.

细节理解题。根据第二段中“In the most recent study, researchers found that when children played for half an hour each day, they were better at organizing their schoolwork”，可知当孩子们每天玩半小时时，他们更擅长组织功课，故选B。

3.

细节理解题。根据倒数第三段中“Results showed that the children in the activity group did better on the tests than those who had no activity.”，可知活动组的儿童比没有活动的儿童表现更好，故选C。

4.

推理判断题。根据短文内容，介绍的是参加户外活动对于改善在学校里的表现的好处，所以应该来自于一本科学书，故选B。
