Do you always forget where you placed your keys or your purse? What was the name of the movie you saw last week? The major cause of your forgetfulness may be linked to what you store in your body, not in your short-term memory bank.

Tests continue to show that people with enough Vitamin B-2 do well in memory exams. The "B" could stand for "brain", if you're one of many with limited instant recall. And the number one source of that vitamin (維生素) is sunflower seeds.

Even when you're sleeping or relaxing, your brain is still at work. Although it makes up just two percent of your total body weight, it uses up to 30 % of the calories (卡路里) you take in each day. For it to work properly, it must be fed. Even if you're not a breakfast eater, that meal is the best way to prepare your brain for the day. A quick and easy English muffin with peanut and butter in it, a glass of milk, and an orange, might be what your brain may be asking you the first thing in the morning when you feel your head is in a fog. Having sunflower seeds and fruit between meals adds more muscle to that hungry, demanding organ. Vitamin B-1 also helps the memory, and that is found in eggs, meats and nuts. In Chinese culture, walnuts are known as the fruit for a long life because it is believed that they feed both the kidneys and the brain. And according to Chinese culture, if you keep those two important organs in good working order, you'll live longer.

However forgetful you are, just keep in mind the letter "B", which will help you to "bear in mind almost everything" even on those days when life's challenges are sending you in a billion directions.

1.The underlined word "muffin" in the third paragraph probably means________.

A. menu B. dinner C. cookie D. calorie

2.What can we conclude from the passage?

A. Two percent of our brain is still active when we are sleeping or relaxing.

B. What we eat seems more important than what we learn in terms of memory.

C. It doesn't make much difference to our brain whether we have breakfast or not.

D. Life's challenges have no effect on our memory, if dealt with in a proper way.

3.In the passage, Chinese culture is mentioned to________.

A. support the idea of long life

B. warn the readers of two organs

C. show the importance of vitamin B-1

D. remind us of walnuts and sunflower seeds

4.What can you get from the passage?

A. Keep in mind the letter "B"

B. The younger, the better memory

C. Learn about Chinese culture

D. Try to get more rest

閱讀下面短文，從各題所給的A、B、C、D四個選項中選出最佳選項。

Scientists have learned a great deal in the last thirty years by studying people as they sleep. They study the bodily characteristics that change during sleep. They have learned that there is one kind of sleep which causes rapid eye movement ( REM ) and another kind with no rapid eye movement (NREM).

Sleep is divided into three stages. In stage one, when you start to go to sleep, you have a pleasant floating feeling. In stage two, you sleep more deeply, and a noise will probably not wake you up. In stage three, the brain waves are less active. This third stage is when you dream, REM tends to signal that we are dreaming. For the rest of the night, you alternate between REM and NREM sleep.

Sleep is a biological need, but your brain never really sleeps. The things that are on your mind during the day are still there at night. They appear as dreams. Researchers say that normal people may have four or five REM periods of dreaming each night. The first one may begin only a half hour after they fall asleep, and the final one may last up to an hour. Nightmares (a frightening dream) usually happen toward the early morning.

Besides dreaming, snoring is also common in one's sleep. People snore because they have trouble breathing while they are asleep. Some snorers have a condition called apnea. They stop breathing up to thirty or forty times an hour because the throat muscles relax too much and block the airway. After a period of time, the brain will signal the person to start breathing again. During this time a person will snore. This is a dangerous condition, because once the brain is without oxygen for four minutes there could be serious brain damage. Sleep apnea can also cause irregular heartbeats, high blood pressure, and a general lack of energy.

What should you do if you have trouble sleeping? Lots of people take sleeping pills, but these are dangerous because they can be addictive. Doctors say the best thing is to try to relax and to avoid bad habits.

Sleep is important to humans. In an average lifetime, 220, 000 hours are spent sleeping, so we need to understand everything we can about sleep. Sweet dreams!

1.Sleep is a(an) ________ need for humans.

A. emotional B. mental

C. biological D. psychological

2.Which of the following conditions is NOT caused by sleep apnea?

A. A heart attack.

B. A lack of energy.

C. Irregular heartbeats.

D. High blood pressure.

3.We can learn from the article that ____________.

A. our brains can get a good rest when we are asleep

B. it's impossible to stop the habit of taking sleeping pills

C. REM and NREM are ways to see if people are in a deep sleep.

D. in stage two people will probably not wake up if they hear a noise.

4.Where is the article probably from?

A. A sports guidebook.

B. A health magazine.

C. A fashion website.

D. A news report.

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flow more slowly but then may become lifelong feelings, extending(延伸) sometimes deeply into both families.

Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time.

Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.

For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

1.Which of the following statements is TRUE according to the passage?

A. Friendships between Americans usually last for all their lives.

B. Americans always show their warmth even if they are very busy.

C. Americans will continue their friendships again even after a long break.

D. Friendships between Americans usually extend deeply into their families.

2.From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be ______.

A. offered a ride to his home

B. treated hospitably at his home

C. treated to dinner in a restaurant

D. warmly welcomed at the airport

3.A suitable title for this passage would probably be “______”.

A. Americans’ and Chinese’s views of friendships.

B. Friendships between Americans.

C. Friendships between Chinese.

D. Americans’ hospitality .

After the examination, the doctor told my parents my sight would get worse and that I would lose my sight finally. On the way home from hospital, no one said a word. One day, would I only imagine the scenery beyond the glass rather than see it?

That September, I entered middle school. Most nights I had homework that included an armful of books to read. To keep up with other children, I took great trouble to finish the task. With my nose a couple of inches from the page, I was tired easily. What’s worse, after I had read several pages on my own, the words slipped off the page into inky pools.

However, then I did not have audio books and electronic devices like kids do now. Instead, Mom volunteered to read out loud. Mom worked part-time, cleaned the house, cooked and spent time with Grandma. In spite of being so busy, she showed up in my room like clockwork. She put on her reading glasses. Mom always thought those glasses made her look old. To me, she looked like a teacher.

In my room, Mom’s voice raced with the ticking of the clock. Being forced to focus on listening, I found a way to keep my marks up and compete with the other kids. When the teacher asked a question, I raised my hand with confidence. Teachers praised me for having a good memory. Reading removed my fear for my failing sight, reading also made me curious about other people’s challenges and how they managed. Though I could not use my eyes to fix on each passage, my mind lit up with every new book.

True to what the doctor said, the worst came, but thanks to Mom, my sense of hearing now allows me to “see”. This was the most precious gift from a mother to her child.

1.Why did the author and his parents keep silent on their way back home from hospital?

A. They all wanted to have a good rest.

B. The author didn’t do well in the exam.

C. What the doctor said made them worried.

D. They focused on the scenery along the road.

2.How did the author manage to get high marks?

A. By being confident.

B. By reading as many books as possible.

C. By getting help from his classmates.

D. By listening carefully.

3.We can learn from the text that ____________.

A. the author’s sight recovered finally

B. reading made the author more sensitive

C. the author’s mother didn’t work to look after him

D. reading made the author not worry about his sight

4.Which of the following could be the best title of the text?

A. My eyesight trouble

Dogs and cats are not for students who live in the dormitory. Just think about the noise, the smell and all that wild behavior—chewing on whatever they can get their teeth on, or knocking over the trash can. But don’t feel sad. There are smaller and less destructive pets to make your dormitory life colorful.

Betta fish

They make great pets with their big personality and astonishing colors, ranging from bright red, dark blue to lemon yellow. Unlike many fish, most bettas react to their owner’s presence and become more active when they are nearby, which is unusual in the fish world.

Chinchillas

Without bad smell, about the size of a rabbit and with fur so dense that they can’t get pests such as fleas(跳蚤), the friendly creature originally from the Andes Mountains in South America makes an ideal indoor pet. Chinchillas are very social animals, so if you only have one, you will become its family. In cold winter days, in a glance at this fury pet in a dorm will bring you a lot of warmth.

Land hermit crabs

In a society where owners are often asked “Are they tasty?”, land hermit crabs are among the most unlucky animals commonly kept as pets. But they are easy to care for, inexpensive and fascinating to watch. And the fact that they don’t cause any allergic reactions makes them perfect for college dormitories.

Red-eared sliders

If you’re interested in a lifelong friend, a red-eared slider makes a wonderful pet. If well cared for, they can live for around 40 years. But there are a couple of things you should know. Red-eared can grow to an adult size of up to 30cm! So you may need a larger tank quickly. In addition, you will need to provide UV lighting, water heater, and a swimming area and a basking (曬太陽) area. Housing a red eared slider is not easy.

1.All the dormitory pets mentioned in the text are _____.

A. active and allergic B. quiet and peaceful

C. colorful and tasty D. small and smelly

2.Which of the following is not true about these creatures?

A. Bettas are active and rich in colors.

B. Chinchillas are originally mountain animals.

C. Land hermit crabs are allergic but tasty.

D. Red-eared sliders need more care from the owner.

3.If you want to keep the pet as long as possible, you’d better choose _____.

A. Betta fish B. Chinchillas

C. Land hermit crabs D. Red-eared sliders

4.The text is mainly to _____.

A. introduce the best way to keep pets

B. offer useful tips for choosing pets

C. inform students of lifestyle of pets

D. recommend some dormitory pets
