Roller coasters are fast and exciting. But passing a painful kidney (腎) stones is not. The process is painful and can take a long time. But American researchers have found that a roller coaster ride just might help those suffering from a kidney stone. They say such rides help patients pass the stones with a 70 percent success rate.

David Wartinger led the study. He found that where the person sits on the roller coaster can make a big difference. He said, “In the pilot study, sitting in the last car of the roller coaster showed about a 64 percent passage rate. Sitting in the first few cars only had a 16 percent success rate.”

It also mattered where the stones were located in the kidney. The researchers found that stones located in the upper part of the kidney model were passed 100 percent.

When it comes to passing kidney stones, not all roller coasters are equal. The researchers used 174 kidney stones of differing shapes, sizes and weights to see if each model worked on the same ride and on two other roller coasters. They found that Big Thunder Mountain was the only one that worked. The other two roller coasters both failed the test. Wartinger said the other rides were too fast and too violent. The movement forced the stones against the side of the kidney. He said that the ideal roller coaster is rough and quick with some twists and turns.

Wartinger thinks roller coaster rides could also be used as a preventative measure. He said that a yearly ride on a roller coaster could even prevent stones from developing. “You need to heed the warnings before going on a roller coaster,” he said. “If you have a kidney stone, but are otherwise healthy and meet the requirements of the ride, patients should try it.”

He adds that it’s definitely a lower cost alternative to other treatments. And riding a roller coaster is definitely more fun!

There is distinction between reading for information and reading for understanding. 1.

The first sense is the one in which we read newspapers, magazines, or anything else. 2.Such materials may increase our store of information, but they cannot improve our understanding. And clearly we don’t have any difficulty in gaining the new information, for our understanding was equal to them before we started. Otherwise, we would have felt the shock of puzzlement.

The second sense is the one in which we read something that at first we do not completely understand. Here the thing to be read is at the first sight better or higher than the reader. The writer is communicating something that can increase the reader’s understanding. 3.Otherwise one person could never learn from another. Here “l(fā)earning” means understanding more, not remembering more information.

What are the conditions in this kind of reading? First, there is inequality in understanding4.  Besides, his book must convey something he possesses and his potential readers lack. Second, the reader must be able to overcome this inequality in some degree. And he should always try to reach the same level of understanding with the writer. If the equality is approached, success of communication is achieved.

5.It is the least demanding and requires the least amount of effort. Everyone who knows how to read can read for entertainment if he wants to. In fact, any book that can be read for understanding or information can probably be read for entertainment as well.

A．Thus, we can employ the word “reading” in two distinct senses.

B．Such communication between unequals must be possible.

C．We can get access to the content of those materials easily.

D．The writer must be “superior” to the reader in understanding.

E. The writer should have a better communicating skill.

F. Besides gaining information and understanding, there’s another goal of reading—entertainment.

G. Reading for entertainment is capable of increasing our understanding for information.

5 Tips for Surviving Shots

Do shots make you nervous? 1. Lots of people are afraid of them because they have a very real fear of needles. So next time your doctor asks you to roll up your sleeve, try these tips.

Distract yourself while you're waiting. Bring along a game, book, music, or a movie player — something you'll get completely caught up in. 2.

Concentrate on taking slow, deep breaths. Breathe all the way down into your stomach. 3. Moreover, concentrating on something other than the shot can take your mind off it.

4. Find a picture, poster, or a sign on the wall. Concentrate on the details. If you're looking at a painting, for example, try counting the number of flowers in the garden, cows in the field, or other images. Or create as many new words as you can using the lettering on a sign. Think about how the message on a health awareness poster might affect you. Whatever it takes, keep focusing on something other than the shot until it's over.

Cough. Research shows that coughing as the needle goes in can help some people feel less pain.

Relax your arm. If you're tense—especially if you tense up in the area where you're getting the shot, it can make a shot hurt more.

Sometimes people feel faint(頭暈的) after getting a shot.5.

A. You are not alone at all.

B. Then they had better not get a shot.

C. Deep breathing can help people relax.

D. Focus attentively on something in the room.

E. Thus,you can make your waiting time shorter.

F. If you feel sick, sit or lie down and rest for 15 minutes.

G. Then you won't think about the shot while sitting in the waiting room.

科目：高中英語 來源：1.1 Unit 1 Warming Up Reading 題型：七選五

七選五

A conflict at work is common. If you can avoid conflict, it means you will win what you want regardless of what the other person wants. Since the potential problem has not been removed, it will simply reappear later. 1

◆Be aware of the fact that some conflicts are unavoidable at work. On many occasions(場合), conflict and disagreement are likely to happen. But when a conflict happens it is not the end of the world. 2 Conflicts mean that people care enough to disagree strongly. The trick is not to allow the conflict to go on forever.

◆ 3 Solve a conflict when it starts, as it only gets worse with time going by. Everyone is waiting for the other to admit he or she is wrong and gets more unpleasant after the conflict has lasted a while. It is necessary to interrupt the "waiting game" before it gets to that point.

◆Ask nicely. If somebody has done something that makes you angry, or if you don't understand their viewpoints or actions, simply asking nicely about them can make a world of difference. Never assume that people do what they do to annoy or hurt you. Sometimes there is a good reason why that person does what he or she does, and a potential conflict disappears right there. 4

◆Appreciate. 5 Tell them why it is worth it to you to solve the conflict. This can be difficult as few people find it easy to appreciate a person they disagree strongly with, but it is a great way to move forward.

A. Praise the other part in the conflict

B. Deal with conflicts sooner rather than later.

C. Invite the other person to talk about the situation.

D. Do remember to make an enquiry, not an accusation of any sort.

E. Here are the necessary steps to effectively get rid of conflicts at work

F. On the contrary, it can be the beginning of an interesting learning process.

G. Clear thinking is unlikely to happen while an argument continues to boil over.
