If you’ve ever had to chop an onion，you probably know that it’s one of the most annoying cooking experiences．It just fills your eyes with tears．Scientists and farmers have been working on a solution to this problem for decades，and they’ve apparently come up with a tearless onion．
Called the“Sunion”，this new vegetable is the result of a natural cross-breeding program that’s been going on farms in Nevada and Washington since the 1980s．It’s supposedly a sweet，mild-tasting onion that doesn’t leave that strong，pungent aftertaste，but what really sets it apart from most other onion varieties is that it doesn’t cause teary eyes when it’s chopped．
When you cut into a normal onion，it releases a compound called lachrymatory-factor synthase，and’when that hits your eyes，your body produces tears．Now，the interesting thing about regular onions is that the amounts of lachrymatory-factor synthase increase the longer the vegetables are stored，so the older they，the more you cry．In Sunions，on the other hand，the levels of that annoying compound drop the more time goes by，until it no longer has any effect on your eyes when you cut it．
That’s what Sunion growers are claiming anyway，but reports from those lucky enough to have tried them seem to confirm these claims．The Huffington Post had three of its reporters chop some Sunions，and apparently，none of them shed a single tear．According to the Washington Post，they don’t have the pungency of regular onions and are so sweet that you can eat them“like popcorn”．
So the good news is that tearless onions are now a real thing．The bad news is that they are currently only grown in Washington and Nevada，and even though they are sold nationwide，they are still in relatively short supply．The first Sunion batches hit the shelves of grocery stores in December，but we’11 probably start seeing them in most grocery shops and supermarkets in the next few years，as more people learn about them．
1.What is special about the Sunion?
A. It’s easily chopped． B. It’s sweet and tastes strong．
C. It’s tearless and mild． D. It’s grown nationwide in the USA．
2.How does the author introduce the Sunion in Paragraph 3 ?
A. By comparison． B. By telling a story．
C. By giving examples． D. By asking questions．
3.What does the underlined word“pungency”in Paragraph 4 mean?
A. Round shape． B. Strong smell．
C. Special character． D. Medical function．
4.What can we conclude from the last paragraph?
A. The Sunion has been largely on the market．
B. The Sunion is still on trial at present．
C. The Sunion will soon be grown worldwide．
D. The author is confident about the future of the Sunion．

If you have ever gone through a toll booth(收费所), you know that your relationship to the person in the booth is not the most intimate you'll ever have. It is one of life's frequent affairs: You hand over some money; you might get change; you drive off.
Late one morning in 1984, headed for lunch in San Francisco, I drove toward a booth. I heard loud music. It sounded like a party. I looked around. No other cars with their windows open. No sound trucks. I looked at the toll booth. Inside it, the man was dancing.
"What are you doing?" I asked.
"I'm having a party," he said.
"What about the rest of the people?" I looked at the other toll booths.
He said, "What do those look like to you?" He pointed down the row of toll booths.
"They look like……toll booths. What do they look like to you?"
He said, "Vertical coffins. At 8:30 every morning, live people get in. Then they die for eight hours. At 4:30, like Lazarus from the dead, they reemerge and go home. For eight hours, brain is on hold, dead on the job. Going through the motions."
I was amazed. This guy had developed a philosophy, a mythology about his job. Sixteen people dead on the job, and the seventeenth, in precisely the same situation, figures out a way to live. I could not help asking the next question: "Why is it different for you? You're having a good time."
He looked at me. "I knew you were going to ask that. I don't understand why anybody would think my job is boring. I have a corner office, glass on all sides. I can see the Golden Gate, San Francisco, and the Berkeley hills. Half the Western world vacations here……and I just stroll in every day and practice dancing."
1.According to the first paragraph, in most cases, how do you describe the relationship between drivers and toll booth?
A．most intimate B．very tense C．pretty ordinary D．extremely hostile
2.Why did the author go to San Francisco?
A. To attend a party
B. B. To have a meal
C. To dance with the worker in the toll booth
D. To hand in the repair fee of his car
3.The underlined name “Lazarus” mentioned in the eighth paragraph probably refers to a person___________.
A. who was very active in his life
B. B. who was dead and revived from death
C. who was going to San Francisco
D. who liked dancing at work
4.According to the passage, which of the following statements is true?
A．The author passed by the toll booth every day.
B．The worker enjoyed his work very much.
C．Only western people like to spend their holidays in the Berkeley hills.
D．The dancing worker was getting badly along with his colleagues.
5.After hearing what the worker said, the author would probably_________.
A．go to the worker’s senior to complain about his bad attitude towards job.
B．go climbing the Golden Gate and the Berkeley hills to have a vacation.
C．learn to take a positive attitude to job and appreciate valuable things in life.
D．go back home instead of wasting time traveling to San Francisco.

How to Overcome Procrastination (拖延症)
If you've ever put off an important task, you know it wouldn’t be fair to describe yourself as lazy. This is just procrastination.
“Procrastination” is derived from the Latin verb procrastinare — to put off until tomorrow. But it's more than just voluntarily delaying. 1.. It means doing something against our better judgment.
We must realize that procrastination is about emotions, not productivity. 2.. Nor are we able to overcome it only by learning ways of self-control. It has to do with managing our emotions in a new way.
3.. This is what researchers found. Students who were able to forgive themselves for procrastinating when studying for a first exam ended up procrastinating less when studying for their next exam. They concluded that self-forgiveness might guarantee future success. It allows students to move pass their improper behavior and focus on the next exam without burden.
Another choice is to make your temptations (诱惑) less attractive. 4.. We can put obstacles between ourselves and our temptations to create a sense of frustration or anxiety. If you keep checking your social media, say, your WeChat, delete those apps from your phone for a while.
Researchers also suggested that we make the things we want to do as easy as possible for ourselves. 5., sleep in your exercise clothes.
A.That may be easier said than done
B.One choice is to explore our curiosity
C.If you feel like running early in the morning
D.So we can’t just download a time management app
E.One option is to forgive yourself when you procrastinate
F.Procrastination also came from the ancient Greek word akrasia
G.It’s still easier to change our surroundings than changing ourselves

If you have ever had a cat, or have watched one of the many funny cat videos online, you’ll know that cats have a mind of their own. A lot of the things they do are hard to understand---they like to climb up tall furniture, fit themselves in small spaces and attack small objects for no reason at all.
Now scientists have managed to figure out what exactly is going on in the brains of our little friends. According to Tony Buffington, a professor at Ohio State University in the US, cats’ strange behavior largely comes from their way of life back in the wild. “Cats today still have many of the same instincts(本能)that allowed them to live in the wild for millions of years.” he said in a TED Talk. “To them, our homes are their jungles.”
In the wild, cats are hunters. Their bodies and great balancing abilities allow them to climb to high spots to better look at the environment. Even though they don’t have to hunt any more in human houses, they still keep the old habit of viewing the living room from, for example, the top of the refrigerator.
Cats’ hunting instinct is also what makes them attack small things like keys and USB drives. In the wild, they hunt whatever they can get, and most of the animals they kill are small.
However, cats can also be prey. This explains why they like to stay in small spaces like drawers or washing machines---they are hiding, or they think they are hiding, from more dangerous animals. This is also why cats prefer a clean box: a smelly one could easily show enemies where they are.
Knowing how cats’ minds work is not only useful for better understanding them. It may also help cats’ owners to better meet cats’ needs. For example, owners could try to make climbing easier for cats by moving their furniture around. They could also use “food puzzles” to make eating feel more like hunting instead of just giving food to the cats.
1.According to Tony Buffington, ________.
A.cats’ strange behavior is hard for people to understand
B.cats are more used to living in the wild than in humans’ homes
C.cats behave strangely mainly because of some instincts in the wild
D.cats’ instincts are as helpful to them today as they were millions of year ago
2.Which of the following statements is TRUE according to the text?
A.Cats like to climb up high because they want to hide from dangerous animals.
B.Cats attack keys and USB drives because they have a habit of hunting small animals.
C.Cats enjoy staying in small spaces because they usually live in small caves in the wild.
D.Cats’ preference for a clean box probably has something to do with their hunting instincts.
3.The underlined word “prey” in Paragraph 5 probably means _________.
A.an animal that is too lazy
B.an animal that likes hiding games
C.an animal that keeps itself clean
D.an animal that is hunted
4.This article is mainly written to _________.
A.explore the reasons behind cats’ strange behavior
B.describe cats’ past wild experience to readers
C.tell cat owners how to make life easier for cats
D.compare cats’ behavior in human homes with that in the wild

Did you ever tell somebody about something that had happened at work or school that day? If so, you were reporting that event. You may think being a reporter means simply getting one's facts straight and telling a story that's of broad, general interest. 1.
To be a good reporter, you need to be able to read, write, speak and listen effectively. 2. So making your communication skills the best they can be is quite important if you want to be a good reporter. Keep a notebook or a journal, and remember to practice noting down what happens, whenever and wherever it happens.
In addition, you should obey the following rules. 3. When an issue is debatable, do your best to cover both sides. Don't assume things, and never make up details; reporters are supposed to seek and report the facts. Lying, making up stories or quotes, or misquoting someone will damage your credibility(信誉).
4. As a reporter your job is to report the facts so that others can form their own opinions. Make sure you present all the important details without twisting them to your own viewpoint.
Generally, a story starts with who, what, where, when, why and how. Build details from there, beginning with the most important information and ending with the least important. By including the most important information first, you allow your editor to cut the back of the story if it runs too long. 5. You can report on current events, or you can do feature stories, which are usually of a more general interest.
Carry a camera and a tape recorder so that you have them on hand whenever you need them. Be prepared to turn over your notes. Your news publisher may want to check your information before publishing it.
A. Strive(奋斗) for accuracy.
B. Reporters should practice noting down whatever happens.
C. You also need to be able to ask good questions.
D. Send out stories you find interesting.
E. End with some important information.
F. Avoid expressing personal opinions.
G. But actually it’s not so easy.
高三英语阅读理解中等难度题查看答案及解析
Have you ever received a gift that was so clearly not your taste that you wondered if perhaps it had been handed to you by mistake? Worse, have you ever given a present and watched your friend look as though she had opened the wrong box? Maybe she responded with a polite “Why, thank you,” but you knew you had missed the mark. Why do presents sometimes go wrong? And what do your choices (good and had) reflect about your personal qualities?
Choosing the right gift is an art, I believe. It calls for empathy－the ability to put yourself into someone else’s head and heart. We’re all able to do this; in fact, we’re born with a kind of natural empathy. After the earliest period of childhood, however, it needs to be reinforced（加强）－by our parents, teachers, friends .When it isn’t, we’re not able to understand other people’s feelings as sharply. This can show in the gifts we select, and so can many other emotional（情感的）qualities.
Think back to the presents you’ve given over the past year, the time and effort you put into your selection, how much you spent, your thoughts while you were shopping ,and your feelings when the receiver opened the package. Keep in mind that what you choose displays your inner world. Of course, you may express yourself differently with different friends, relatives, and other people you know.
We live in a society where exchanging presents is an important part of communication. Ignoring the tradition won’t make it go away. If you really dislike such a tradition, tell your friends ahead of time.
1.The underlined expression “you had missed the mark” means “you had failed to________”.
A. make her feel better
B. keep your friendship
C. receive a present in return
D. get the expected effect
2.Which of the following is the main idea of the second paragraph?
A. Natural empathy needs to be reinforced.
B. Emotional changes influence one’s choice of gifts.
C. Selecting the right gift is an ability people are born with.
D. Choosing gifts requires one to understand the receivers.
3.In the third paragraph, the author tells us that .
A. attention should be paid to the receiver’s responses
B. one learns from what he did in the past
C. the choice of girls reflects one’s emotional qualities
D. one should spend more time choosing gifts
4.The best possible title for this passage is “ ”.
A. Ways of Choosing Gifts
B. An Important Tradition
C. Exchanging Presents
D. Message in a Gift

根据短文内容，从短文后的选项中选出能入空白处的最佳选项。选项中有两项为多余选项。
Did you know that if you need an alarm clock to wake up in the morning, you’re probably sleep-deprived （缺失）? __1._______ . On average, American teens get two hours less than the average 9.2 hours of sleep they need each night to function at their best.
There are many reasons why teens don’t get enough sleep. ____2.______ . When your parents were young, they might have read a book or watched television before trying to go to sleep. But today’s teens are likely to be surfing the Internet, texting, emailing, or playing video games right before bed. ___3._____ . And using them right before bed can result in difficulty getting to sleep. According to a survey by the National Sleep Foundation, teens with four or more electronic equipment in their rooms are much more likely than their peers to get an insufficient amount of sleep at night, and are almost twice as likely to fall asleep in school and while doing homework.
___4.______ . In the National Sleep Foundation survey, three-quarters of the teens took at least one drink with caffeine every day, and nearly one-third consumed two or more every day. With all the trendy “high-energy” drinks and coffees out there right now, it’s easy to get a caffeine overload and that’s not good for sleep.
So what can you do if you’re in lack of sleep? “The good news is that you only have to make up about a third of what you have lost, to function and feel better,” says Dr. Mahowald at a sleep disorders center. ____5.______ . But sleeping until noon on the weekend can cause problems — you’ll likely be wide-eyed until late those nights. Instead, try keeping a reasonable, regular sleeping and waking schedule.
A. One of them is a relatively new development.
B．Those extra two hours of sleep on Saturday and Sunday mornings can really help.
C．Most teens don’t get enough sleep.
D．Many teens also drink too much caffeine to sleep well.
E．Electronic devices are more exciting than simply watching television.
F．Researchers also have found that biology plays a role in teens’ sleep patterns.
G．Many school districts are shifting their start times to later morning for school students.
