第二部分阅读理解（共两节，满分40分）
第一节（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
A
Bananas belong to the most popular and most eaten fruits in the world. They were first recognized as an edible fruit in the Southeastern part of Asia as far back as 5000 BCE and they were first grown in tropical India and Southeast Asia, from where they were brought to all parts of the world.
However, the banana is in danger of becoming extinct. Scientists have found that a virus has been attacking Cavendish bananas, the most widely-eaten banana, in Asia and Australia for some years. At the moment there is no way to fight off the
disease. Because bananas are grown in plantations（种植园）, where a disease can attack all of the bananas of the same kind. It spreads through infected plants, soil and water.
The new virus is similar to the Panama disease（黄叶病）which wiped out certain types of bananas in the 1800s. The disease attacked the banana plant and killed it off completely. Scientists fear that the new virus called Tropical Race 4, a mutation（突变）of the Panama disease, will eventually spread to Latin America, where most of the world’s bananas are produced. It has already destroyed whole plantations in south-east Asia and northern Australia.
Although Tropical Race 4 has been around for some decades, it has spread more quickly in the past few years. At present, food experts are trying to contain the disease and stop it from spreading to other continents. Millions of people around the world rely on the banana as a source of food. About 12% of the world’s banana production of over 140 million tons are exported.
21. The underlined word “edible” in the first paragraph means .
A. beautiful in sight
B. delicious to taste
C. unsuitable for use as food
D. safe to eat and not poisonous
22. It can be inferred from the passage that .
A. the disease can spread through the air
B. the Panama disease is not infectious at all
C. food experts are doing research to fight off the disease
D. the virus attacking bananas will be killed very soon
23. Which section of a newspaper is the passage most probably taken from?
A. Entertainment.
B. Culture.
C. Science.
D. Sports.
B
The first step to taking care of yourself and reduce stress is to make sure that your environment is in order. Seeing your house in a mess can affect your mood and make your personal space a place you want to escape from. Here are some things you should consider cleaning from your home:
Old magazines and books
Get rid of old magazines and books you have lying around and no chance to read again. Find places where you can donate to such as child care centers, doctor’s offices, nursing homes, and libraries. If there’s an article that really speaks to you, scan a digital image of it and keep it in your computer.
Receipts（收据、发票）, bills and documents
Throw away receipts for items that you aren’t planning on returning. If you’re cautious about throwing away receipts, you can make a digital copy of them with a basic scanner.
Clothes
Use the two-year-rule for clothes--get rid of clothes that you haven’t worn in two years. Sell them to a second-hand store or donate them to the needy.
Medicine and vitamins
Take a look at your medicine closet and clear out drugs that have expired, medicine that has sat on your shelf for too long, or ones that you no longer use. Check to see what the proper disposal methods are for the medication.
Jewelry
Go through your jewelry and deal with the broken jewelry and make plans to sell ones that you don’t wear. For fine jewelry, look up appraisers（鉴定者）from the National Association of Jewelry Appraisers. Once you have a quoted price, shop around at auction houses, pawnshops（典当铺）, and jewelers to see if you can find a better deal.
Some souvenirs
Many organizing experts advise throwing away souvenirs like cards and gifts you don’t use. I agree, but I think you can keep some of them by perhaps creating some sort of poster with old cards or designating a small shoe box for souvenirs. Decide to throw away anything that can’t fit into the box.
24. This passage gives some advice on how to .
A. make your place in order
B. throw away all the unwanted things
C. donate the unwanted things
D. recycle the unwanted things
25. The underlined word “expired” in Paragraph 5 means “”.
A. existed
B. begun to be taken
C. become useless
D. stayed long
26. According to the passage, can be donated.
A. old magazines and clothes
B. old books and jewelry
C. old souvenirs and documents
D. receipts and medicine
27. From the passage, we can learn that .
A. all the unwanted jewelry should be removed
B. all the souvenirs can’t be throw away
C. the medicine are too expensive to be deserved
D. none of the receipts can be got rid of
C
I wanted to act since I was six years old, after seeing Star Wars, but my goals were more “wear a sweet costume and pretend to be cool” than “be famous.” So the fact that I starred in the sitcom（情景喜剧）iCarly at age 14 and was thrown into teen stardom was both an exciting and unexpected journey.
When iCarly first started growing in popularity back in 2007, my colleagues and I quickly felt the swell in attention. I started getting invited to movie premieres （首映）, designers were sending me clothes, old friends were reaching out, and I could no longer get to a public place without getting asked for a picture or an autograph. It was all pretty cool. At the time I didn’t realize I was losing myself, but I was.
Somewhere in 2009, the show hit a really sweet spot in its success and the ratings were huge. iCarly was watched in millions of households on a daily basis, and once I had to be escorted（护送）from a water park with my colleagues because of danger issues caused by the overwhelming crowd of fans.
As the show grew in success, so did my desire to get back to a private life. I started feeling like I was always on my guard. It seemed everywhere I went, someone wanted or needed something from me.
People had expectations of me. My job was simple: Do everything anyone around me wanted and smile doing it. There were times when I considered walking away from it all...
But I couldn’t. For every “negative” thing of fame, they were positives. Being on television made me cooler, made people love me, gave me the ability to do things others couldn’t dream of, and let me get away with more. What’s not good about that?
People start in entertainment to make art in the way they know best, and they try to leave their marks on the world. That’s such a pure, hopeful, dreamer’s
goal--we’re here to entertain, and we’re lucky to do so.
28. The writer wanted to act when she was very young because .
A. she hoped to be famous.
B. she was invited to movie premieres
C. She wanted to be pretty and pretend to be cool
D. the sitcom was so popular
29. Which of the following statements is TRUE?
A. The writer’s private life was greatly disturbed because of her popularity.
B. The writer once gave up because of the great pressure from work.
C. The writer didn’t know whether to go on with her career.
D. The writer didn’t think it a good thing to be famous.
30. What did the writer think of being in the entertainment industry?
A. She was tired of it.
B. She wanted to run away from it.
C. She felt lucky to be there to entertain people.
D. She was there because she was wanted.
31. Which is the best title of the passage?
A. My Life as A Star
B. My Rewards as An Actor
C. My Road to Success
D. My Role in Entertainment
D
Is a college education worth the price? This is a question more Americans are asking as college costs continue rising and the job market remains weak.
According to College Board, a private company, attending a four-year college in the USA can cost more than $40,000 a year. Many college people are drowning in student debt. They had to borrow money to finance their education.
A recent study from the Hamilton Project suggests that a college education is worth it, at least in the USA. The study found someone with a 4-year college education earns two times as much as a high school graduate over a lifetime. And for nearly all study programs, an individual with a four year bachelor’s degree earns even more than someone with a two-year degree.
But not all college majors have a guarantee of good salaries. For example, a chemical engineer can expect to earn double the earnings of a social worker over a lifetime. On average, a finance graduate makes more than a nurse or medical aide, while the nurse makes more than a primary school teacher.
Generally, college majors that require skill in mathematics have high lifetime earnings. Graduates in computer science, engineering, and physics have the highest wages. Majors that involve teaching children or counseling（咨询）have the lowest pay.
The study did not explore the earnings of people with master’s degrees or doctorates.
The Hamilton Project noted that future earnings should not be the only reason for choosing a college major. It says, “Personal enjoyment, engaging in meaningful work, and filling a social need should also enter into a student’s decision-making.”
Study organizers hope the report will help students make better decisions about higher education. In 69 heir words, “College degrees may not be a guarantee of higher income, but they come closer than just about any other investment one can make.”
32. According to the passage, which of the following statements is TRUE?
A. When choosing a major, students should consider their family income.
B. A student with a 4-year college education is sure to earn much more money than one with a
2-year degree.
C. The earnings of students with higher degrees are not discussed.
D. All college majors don’t have better earnings.
33. The study intends to .
A. help students choose suitable subjects in the college.
B. persuade high school students to receive higher education
C. show that a college education is worth the price
D. make high school students aware of their decisions about higher education
34. What can we infer from the passage?
A. A student from a low-income family can’t go to college.
B. Students are more likely to major in computer science because of the high wage.
C. The nurse has the lowest income among all the majors.
D. Students should take many factors into consideration when choosing a major.
35. The passage mainly talks about .
A. whether it is worthwhile to go to college
B. how to choose a major at college
C. whether it is necessary to go to college
D. how to guarantee good salaries in the future 第二节（共5小题；每小题2分，满分10分）
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Do you want to say goodbye to bad habits? This following steps may help you a lot.
36 Make a note every time you are driven by bad habits. Write down the time and where you are, as well as how you’re feeling. Are you bored, angry, sad? The more you understand the why behind your habit, the more control you’ll have over it.
37 Do you see any patterns in your journal? Do you always bite your nails before a test? Are you more likely to eat junk food, like chips or candy, when you’re doing your homework? If you notice a pattern to your habit,start thinking about ways you can change the pattern. For example, if you bite your nails when you’re stressed, try to find other ways to calm yourself, like taking slow, deep breaths.
Replace your bad habit with a good one. Instead of biting your nails or twirling your hair, keep your fingers busy sketching or knitting. If gossip is your problem, challenge yourself to say nice things about people. You can replace your new activity with your old one each time. 38
Stay focused. 39 “I will stop biting my nails.” Or “I will stop texting so much.” Make a list of the days of the week, and place a gold star next to each day that you aren’t driven by your habit. Before you know it, you’ll have a whole page
of gold stars!
Keep at it. Maybe you’ve heard the expression “Old habits die hard.” Well, it’s true! 40 So if you mess up one day, don’t beat yourself up over it--but don’t give up, either! Finally, you’ll succeed.
Remember, if you put your mind of it, you can do anything--even break that bad, bad habit!
A. Try to find ways to get rid of the bad habits.
B. Write down a promise to yourself:
C. Pay attention to when your bad habit appears suddenly.
D. Keep a journal for a day or two.
E. Old habits can never be removed.
F. This way you’ll be one step closer to breaking that bad habit.
G. It usually takes three weeks to month to break a bad habit.

Dear classmates,
More and more students are riding electric bikes or motorbikes to school, which brings high security risks. Therefore, I’m writing this le tter to call on students to pay attention to safe travel.
To begin with, the ways of travelling should be taken into consideration. Going to school on foot, by bike, or by bus, is much safer than riding electric bikes. Secondly, we should observe the traffic rules and follow what the traffic signals tell us to do. For example, we must go on sidewalks when walking. In no case can we run a red light and overspeed driving is not a clever way, either. What’s more, we can tell our relatives and friends not to dr ive after drinking alcohol. Only when each of us raises our awareness about safety travel can we reduce security risks and travel safely.
Yours,
Li Hua

Good afternoon, shoppers. We need your attention. We have a lost boy at the front of the store. He has been in the manager’s office for 10 minutes, and no one has come forward to ask for him.

2015电磁场期末考试试题
三、简答题 1、说明静电场中的电位函数，并写出其定义式。 答：静电场是无旋的矢量场，它可以用一个标量函数的梯度表示，此标量函数称为电位函数(3 分)。静电场中，电位函数的定义为grad ??=-=-?E (3 分) 2、什么叫集肤效应、集肤深度？试写出集肤深度与衰减常数的关系式。 高频率电磁波传入良导体后，由于良导体的电导率一般在107S/m 量级，所以电磁波在良导体中衰减极快。 电磁波往往在微米量级的距离内就衰减得近于零了。因此高频电磁场只能存在于良导体表面的一个薄层内， 这种现象称为集肤效应(Skin Effect)。电磁波场强振幅衰减到表面处的1/e 的深度，称为集肤深度(穿透深度)， 以δ表示。 集肤深度 001E e E e αδ-=? ? 1 δα= 3、说明真空中电场强度和库仑定律。 答：电场强度表示电场中某点的单位正试验电荷所受到的力，其定义式为： () ()r r q = F E (3 分)。库仑定律是描述真空中两个静止点电荷之间相互作用的规律，其表达式为：'20=4R q q R e πεF (3 分)。 4、用数学式说明梯度无旋。 答：x y z x y z ????????= ++???e e e (2 分) ()x y z x y z x y z ??????? ???= ?????????e e e (2 分) 222222()()()x y z z y z y x z x z x y x y ????????????=---+-????????????e e e (2 分)
