But if you are a book lover just like me, read a book you like for half an hour. Hold the book close to your face, and you’ll lose yourself in the stories of the book and it helps you stay in a good mood.
For sure, there’s nothing better than laughter. Though life is not easy and full of problems, laughter is the best medicine. It can really keep worries away from your mind! Very often I call my best friend and we tell each other about our good times or something funny, and I’ll feel better before I know it.
Try these methods when you worry about an exam, and you will feel much better.

【解析】1．句意：她过去喜欢吃汉堡包和薯片等垃圾食品，而且她从不运动。
前文提到Jane过去爱吃垃圾食品，后文说她每天坐几小时写作业或玩电脑，能看出她完全不做运动，选exercise“锻炼”，符合语境。homework“作业”、housework“家务”、reading“阅读”都不符合。
2．句意：医生告诉她饮食不好，需要改变生活方式。

3．句意：她开始每天早上锻炼，在公园跑20分钟。
医生让她改变生活方式，后面提到每天早上在公园跑20分钟，说明她开始锻炼，选exercise“锻炼”，符合语境。relax“放松”、study“学习”、sleep“睡觉”都和后文跑步的动作对应不上。
4．句意：她还停止吃垃圾食品，开始吃更多的蔬菜和水果。
根据“stopped eating junk food”及健康饮食常识，蔬菜和水果是健康搭配，选fruit“水果”，符合语境。junk food“垃圾食品”、meat“肉”、chocolate“巧克力”都不符合健康饮食的要求。
5．句意：两周后，她感觉好多了。
她坚持健康的生活方式两周后，上课能集中注意力不犯困，说明身体好多了，选better“更好的”，符合语境。worse“更差”、sadder“更伤心”、angrier“更生气”都不符合。

keep a balance between...and...“在……和……之间保持平衡”，是固定搭配。

9．句意：他们不再担心她的健康了。
父母看到她状态进步，自然不再担心她的健康，worry about“担心”，符合语境。talk“交谈”、think“想”、learn“学习”都不符合。
10．句意：Jane意识到照顾身体不仅是为了现在，而是为了她的一生。
根据“not just for now”可知，是长远的时间概念，whole life“一生”，符合逻辑。day“天”、week“周”、month“月”都和“不仅是为了现在”的长远含义不匹配。

62．句意：一个11岁的女孩说，她通过色彩漫步在普通的街道里找到了新的乐趣。此处泛指“一个11岁的女孩”，“11（eleven）”以元音音素开头，不定冠词用an，句首单词的首字母需大写。
63．句意：人们可以在色彩漫步期间享受一段放松的时光。情态动词“can”后接动词原形have。
64．句意：下次，选一种颜色，散散步，享受你周围多姿多彩的世界。修饰名词“world”用形容词colorful/colourful“多彩的”。
65．句意：它教会我们热爱生活，在各处发现美好。动词“teaches”后面要跟人称代词的宾格作宾语，we的宾格是us。

How to Be a Sunny Person
Hello, everyone. I am glad to be here to give you a speech about how to be a sunny person.
First, we should use the Internet properly. Don’t spend lots of time on computer games but use it for study. Besides, take more exercise like running or playing basketball to keep fit. It’s meaningful to develop hobbies such as reading and listening to music. Also, we need healthy eating habits: have three meals on time and eat more vegetables.
In a word, if we try our best, we will become better and better. I hope each of you can be a sunny person.
