Unit 4 Astronomy- the science of the stars课时作业Learning about language.阅读理解ABy May, after three months, I had lost 22 pounds and reached my goal of 115 pounds. My friends would say “Alice, you look great！” or “How did you lose so much weight？” Those compliments(赞扬) made me feel good and confident. Soon I dropped to 110 pounds. A few of my friends told me that I need to stop dieting because I was starting to look sick. They brought me a presenta bag of chocolates, which I later gave to my sister. My mum would come to my room, with tears in her eyes, and have long chats about how harmful this diet was and begged me to stop. My dad would leave worried messages on my cell phone at school, telling me that it would do serious harm to my body. By midJune, when school was coming to an end, I was down to an only alive state of 95 pounds. All of a sudden, I knew I had to do something. I guessed the number itself scared me. I recalled my doctor. He told me about a girl who was 95 pounds and was at the risk of dying. I knew I was putting my life at risk, but for what? To make those who love me worried? Is it worthwhile to be thin? Now I realize that models in magazines, TV and movies are not realistic. The price to pay for the “perfect body” is living with the dangerous and sometimes deadly eating disorder. And there are more important things to think about than how thin you are.【文章大意】文章通过作者的亲身经历告诉大家不健康的饮食会导致严重的健康问题。1. How did the author feel when she weighed 115 pounds?AHappy. BDisappointed.CWorried.

For example, laughter can lead to healthy physical changes in the body. Humor and laughter strengthen your immune system, develop your energy, and protect you from the damaging effects of stress. Laughter makes you feel good and the good feeling you get when you laugh remains with you even long after the laughter. Laughter can also help you keep a positive outlook through difficult situations. In addition, laughter can benefit us in our social life. For example, humor and playful communication strengthen our relationships by causing positive feelings and developing emotional connection. More importantly, humor is a powerful way to heal disagreements and hurts, and as a result, laughter unites people during difficult times. Therefore, its important to include humor and laughter into life. Here are some ways to start: When you look at someone or see something even mildly pleasing, practice smiling. Make a list of the good things in your life, which will distance you from negative thoughts that are a barrier to humor and laughter. More often, people are happy to share something funny because it gives them an opportunity to laugh again. Thus, when you hear laughter, seek it out and ask, “Whats funny？”Besides, its also a good idea to spend time with those who laugh easily both at themselves and at lifes absurdities(荒谬) To enjoy more benefits of laughter, we also need to see the lighter side of life, So, laugh at yourself and talk with others about times when you feel embarrassed. Look for the humor in a bad situation, and this will help improve your mood and the mood of those around you. You can also keep a toy on your desk, or put up a funny poster in your office. These things can remind you of the positivity of your life.【文章大意】 本文为说明文，题材为日常生活类。本文主要介绍了笑的好处以及如何在生活中更多地欢笑。5.

Here are some things to consider before giving your child the green light to cruise campus(大学校园) From a safety standpoint, college students are better off not having a vehicle on campus, especially at first. Just a year or two of driving experience makes a big difference to young people. Per_mile_driven,_teens_are_three_times_as_likely_to_have_deadly_crashes_as_drivers_20_or_older,_according to the Insurance Institute for Highway Safety. Its no secret that college campuses are flooded with alcohol and that students have little trouble finding it. With no parents in sight, many struggle to drink. Not exactly the best time to have a car at hand. Assuming your child is on your car insurance policy, a crash he or she causes at college will come home to roost (应验到说出者本人身上) in the form of rate increases. NerdWallet found that annual rates for a couple with an 18yearold increase by an average of $536 after a crash by the teen. Even if your child keeps clear of trouble, friends who borrow the car might not. Accidents caused by anyone driving your car can send your rates increasing at renewal time. Some parents may take comfort in knowing their kids have a car on campus, making it easier to get around and visit home. But taking a vehicle to school brings some major headaches for students, too. For one thing, parking can be inconvenient. As a result, some universities dont allow freshmen (大一新生) to bring cars at all. Theres also the burden of giving rides to other students who dont have a car. In view of safety and expense, a bicycle or bus pass sounds like a nicer choice. 【文章大意】 本文为议论文，题材为日常生活类。随着人们生活水平的提高，越来越多的大学生加入了有车一族，开始奔驰于大学校园。固然，私家车提供了便捷，却同时也隐藏着一些隐患。9.

Why arent freshmen allowed to bring cars by some colleges?ABecause there isnt enough room for parking.BBecause they want to prevent car accidents.CBecause freshmen cant afford parking fees.DBecause young car owners are the envy of those with no car.解析：A细节理解题。根据第四段的For one thing，parking can be inconvenient.As a result, some universities dont allow freshmen to bring cars at all可知，是因为大学里的停车位不够。12. What is the main idea of the text?ACollege students should leave their cars at home.BCollege students should gain driving experience.CColleges shouldnt let students drive on campus.DParents shouldnt let their teenage children drive.解析：A主旨大意题。根据文章内容可知，作者主要从三个方面表明家长不该让孩子在大学校园里开车。.七选五 A humble (谦逊的) person isnt proud and doesnt believe he is better than other people. _1_ It can help you be more content with your life, and also help you get along better with others. Its also essential to being an effective learner. If you think you know it all, you wont be openminded enough to seek out new knowledge. Pretending to be humble isnt the same as being humble. Often people who pretend to be humble do it to seek out praise. _2_ And they know that, even if you fool some, you wont get the same benefits as you would through actually developing modesty. Similarly, dont confuse being humble with being sycophantic (阿谀奉承的) _3_ In other words, you should understand your limitations. Even if youre the best in the world at doing something, there are always other things you cannot do. We make judgments about others all the time, usually without even realizing it. _4_ Whenever you do it, judge yourself instead and consider how you can improve yourself. Your appreciation for the talents and qualities of others also can help you learn to be humble. _5_ Its nearly impossible to be humble when were trying to be better than others. So avoid meaningless comparisons, and youll be able to enjoy doing things without worrying about whether youre better or worse at them than others.AOthers will recognize this.BBeing humble is of great importance.CTo learn to be humble, you need to evaluate yourself.DIf you feel youre better, you have no motivation to improve.E. Being humble is also an excellent tool for selfdevelopment in general.F. So challenge yourself to look at others and appreciate the things they can do.G. Therefore, try to catch yourself in the act of judging another person or group of people.【文章大意】本文为说明文，题材为社会生活类。本文主要介绍谦逊的方法。1解析：B谦逊是重要的，它让你学会知足和与人相处。由此可判断选B项。2解析：A有些人为了寻求表扬假装谦虚，这一点其他人就会看得出来。由此可判断选A项。3解析：C为了学会谦虚，我们有必要自我评估，即需要了解自己的不足，由此可判断选C项。4解析：G我们总会不自觉地对别人品头论足，因此我们有必要改掉这一坏毛病，当我们在评价他人时，多想想自己又做得如何，该如何改进。catch sb. in the act of doing sth.意为“发现某人做(坏事)”。5解析：F学会欣赏他人，欣赏他们所做的事，这也是一种谦虚的途径。
