Sudoku (数独) puzzles give your brain a hard time: Every number from 1 to 9 must appear in each of the nine horizontal (横向的) rows, in each of the nine vertical columns and in each of the nine boxes.
For many of us, this can be a reason for a headache, but in the very rare case of a German man, a Sudoku puzzle even caused seizures (痉挛).
In a new case study from the University of Munich, published in the Journal of the American Medical Association, Dr. Berend Feddersen introduces a student who was 25 years old when he was buried by a snow slide during a ski tour. For 15 minutes, he didn’t get enough oxygen, which severely damaged certain parts of his brain. “He had to receive treatment on the scene. Luckily he survived,” says Feddersen, the author of the study.
Weeks after the accident, when the young man was ready for recovery treatment, something bizarre happened: When the patient solved Sudoku puzzles, he suddenly had seizures of his left arm — something the medical world hadn’t seen before.
Feddersen explains: “In order to solve a Sudoku, the patient used parts of his brain which are responsible for vision-space tasks. But exactly those brain parts had been damaged in the accident and then caused the seizures once they were used.”
This particular case is an example of what doctors call reflex epilepsy (反射性癫痫), according to Dr. Jacqueline French, professor from NYU Langone School of Medicine.
“You have to have an injury of your brain first, and then seizures like that can happen,” she says.
In the meantime, the patient from the case study stopped solving Sudoku puzzles forever and has been seizure-free for more than five years. “Fortunately, he can do crossword puzzles. He never had problems with those,” Feddersen says.
1.In the accident, the student ______.
A. began to experience seizures in his left arm
B. got the vision-space part of his brain damaged
C. had to be sent to hospital as soon as possible
D. found his Sudoku ability seriously weakened
2.It can be learned from the text that ______.
A. the man cannot complete crossword puzzles now
B. it is Sudoku playing that brings about his seizures
C. the man’s symptoms are common and widely observed
D. the seizures cause much trouble to the man’s daily life
3.This text can be best described as______.
A. a medical test B. a warning to skiers
C. a news report D. a research paper

As you can see，water works hard in your body every day.That’s why it’s important to give your body the water it needs to carry out all its different jobs.On a regular day，your body loses 2 to 3 quarts of water—enough to fill a 2liter soda bottle.You probably guess that water is lost when you sweat—especially on a hot day.
But your body also loses water in an almost invisible way—evaporation (蒸发)．Water escapes from your body through your skin and in your breath.How？Your breath contains droplets (小滴) of water that are usually too tiny to see.They become visible for a quick second in the cold when you can “see your breath”．But water evaporates this way all year round.Your skin also contains water，which escapes in tiny droplets that go into the air.The water in your skin evaporates into the air，but fortunately，your body can replace the water it loses so your skin doesn’t dry out.
Eating and drinking is one way to replace the water your body loses.Most foods have a lot of water in them，especially fruits and vegetables.Grapes，watermelons，oranges，and cantaloupes are delicious and full of water.
But you can’t rely_on food alone to get that water back，and that’s why it’s also a good idea to drink water every day.You might have heard someone say that people need to drink 6 to 8 cups (1.4 to 1.9 liters) of water each day.Depending on how much water you’re getting from foods and other liquids,6 to 8 cups might not be necessary.If you eat a lot of fruits and vegetables，or you like to eat soup every day，you’ll get some of the water your body needs.
1. You should drink enough water every day because________.
A．your body needs too much water
B．water does all kinds of jobs in your body
C．your body loses a lot of water every day
D．the more water you drink the better you feel
2. Water in your body loses by the following ways EXCEPT________.
A．breathing B．evaporating
C．sweating D．eating
3. Your body has to give enough water to your skin in order to________.
A．keep the water in your skin clean
B．stop your skin from drying out
C．stop the water from losing
D．keep your skin clean all the time
4. What does the underlined phrase “rely on” in the fourth paragraph mean?
A．Eat up. B．Receive.
C．Depend upon. D．Digest.

“Don’t be afraid to give your best to what seemingly are small jobs. Every time you conquer one it makes you much stronger. If you do little jobs well, the big ones will tend to take care of themselves,” said Dale Carnegie.
Sometimes, doing your best work or trying your hardest at something is difficult. It may have something to do with trying to do something new for the first time, like a new sport or activity at school. It may have something to do with doing homework for a subject that is not your favorite or is not your best.
As Hunter S. Thompson once said, “Anything worth doing is worth doing right.” And as Albert Einstein added, “We have to do the best we can. This is our sacred human responsibility.”
Developing the habit of trying your hardest and doing your best is something that will help you succeed throughout your life. If you have looked at some quotes related to trying your hardest, you will see that many of them come from people who have made a big difference in the world. This is not a coincidence. It was not only their cleverness that helped them stand out and change the world, but their ability to try their hardest and do their best in whatever they were doing. If you can develop this same habit---to do your best in any situation, it will be a great benefit to your family, career, school and community.
As Bob Cousy put it, “Do your best when no one is looking. If you do that, then you can be successful at anything you put your mind to.” The choice is yours.
1.Why does the author use the quote of Dale Carnegie in Paragraph 1?
A. To describe a scene. B. To introduce a topic.
C. To draw a conclusion. D. To support an argument.
2.According to the passage, in which case is it difficult to try your hardest?
A. When you are doing something that you are familiar with.
B. When you are doing something that you are good at.
C. When you are doing something that you feel bored with.
D. When you are doing something that you like very much.
3.Why does the author suggest we develop the habit of trying our hardest?
A. To let us make a big difference in the world.
B. To help us achieve success all through our life.
C. To make us more skillful in our work.
D. To make it possible for us to benefit the whole world.
4.What is the main purpose of the passage?
A. To inform. B. To advertise.
C. To introduce. D. To persuade.

The next time your brain refuses to recall a simple fact or name, be thankful. That could be a sign that your brain is getting rid of unnecessary information so that it can operate more efficiently, and help you make better decisions.
The researchers say there are numerous neurobiological(神经生物学的)studies conducted on how the brain stores information, a process called persistence (暂留). However, scientists also assumed that our occasional inability to recall facts was due to a are an the brain. In 2013, scientists discovered that as new neurons combine with the hippocampus(海马区)----a region of the brain that plays a significant role in learning and remembering---they overwrite old memories, making them harder to access. There is also evidence that the brain weakens or removes connections between neurons, in which memories are encoded.
The scientists have a theory on why the brain spends so much energy erasing memories. They say what the brain decides to forget is determined by our daily life. An example is that our brains remember phone numbers according to the need. Instead of storing this irrelevant information that our phones can store for us, our brains are freed up to store the memories that actually do matter for us. They also believe that memorizing too much detail could prevent us from making good decisions.
So the next time you are unable to recall a seemingly important fact, don’t be hard on yourself. Just throw it to your brain’s “rubbish can” to make room for information that can contribute to making you smarter! Remember, even Albert Einstein was absent-minded!
1.What can we know from the first two paragraphs?
A. Persistence is not a process to store information
B. Once information is stored in the brain, it will last forever
C. Learning and memorizing take place in the hippocampus
D. New neurons will strengthen old memories
2.The brain has to erase memories to __________.
A. recall important information
B. store more important information
C. store detail
D. remember phone numbers
3.If some unimportant information is stored, it will be _________.
A. combined with the hippocampus
B. processed and memorized permanently
C. stored and decoded immediately
D. removed and forgotten soon
4.What is the best title of the passage?
A. Scientists encourage us to forget things
B. The way our brains memorize and encode
C. Forgetting things may make you smarter
D. Why was Albert Einstein absent-minded?
