We have known for a long time that flowers of different plants open and close at different times of day. This is so 1 that there seems to be no need to ask the reason for it. Yet no one 2 understands why flowers open and close like this at particular times. The process is not as 3 as we might think, as recent experiments have shown. In one study, flowers were kept in constant 4 . We might expect that the flowers, without any information about the time of day, did not open as they 5 do. As a matter of fact, they 6 to open at their usual time. This suggests that they have some mysterious(神秘的) way of knowing the 7 .

However, it was later found that not just plants but also 10 , including man, have this “inner clock” which 11 the working of their bodies and influences their activities. Men, then, are also influenced by this mysterious 12 . Whether we wish it or not, it affects such things in our life as our need for sleep, our need for food.
In the past, this did not really 13 because people lived in natural condition. In the 14 world, things are different; now there are spacemen, airplane pilots and, in ordinary life, a lot of people who have to work at night. It would be very 15 , then, to know more about the “inner clock”. Such things as flowers might help us understand more about ourselves.

Getting away for a short time always seems like a great idea—until you have to pack. The rule is: pack light. Here are some tips to help you pack.
Organize Yourself
Make a list. Think of what you need from your head to your toes. When you’ve done this once, it’ll be easier next time.
Start Small
Consider buying small-size samples of shampoo, toothpaste, and other items at your local store. Make sure they are all sealed tightly.
In an emergency, you can purchase them at your destination. But remember that the time you spend buying things at your destination will reduce your visiting time.
The Clothing Dilemma
Choosing which clothes to bring is probably the hardest packing decision to make. Think once again from head to toe — hat, shirts, jeans, sneakers, etc. Once you’ve picked out what you want to bring, think carefully. Do you really need that extra pair of jeans? If so, fine. Don’t try to fool yourself. You are the one who will be left holding the bag.
Weather is an important factor in your packing. If it’s cold, you could wear a jacket, a sweater, a regular shirt, and a T-shirt. Layering up will keep you warm and it will leave more room in your bag. Roll up your casual clothes instead of folding and laying them flat. This leaves more room to pack other things, and keeps your clothes fairly wrinkle-free.
Remember how much easier it will be to carry your bag!
1.This text would be most helpful to a reader who is _______ .

A. lighten your load
B. save a lot of money
C. have more visiting time

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。
Health experts have long known that vitamin D is important for healthy bones and teeth. It may also help to protect the body against diseases such as diabetes and cancer. And now, researchers say vitamin D might help fight brain diseases called dementia (痴呆).
Dementia is a brain disease that damages thinking and memory processes, which scientists call “cognitive (认知) abilities.” Dementia is difficult to treat. Taking care of someone who has dementia is extremely demanding. And the disease is very frightening to sufferers. Chris Roberts suffers from dementia. He says the worst part of living with this disease was getting lost while driving. “The worst thing that I found was getting lost in the car, not just forgetting where I was going— I wouldn’t know where I was.” More than 47 million people around the world suffer from dementia. The World Health Organization reports that 60 percent of them live in low- and middle-income countries.
We get vitamin D from some foods like nuts, lentils (扁豆) and fatty fish. We also get vitamin D from the sun. But that is not dependable. In some parts of the world, there is not enough sunlight to provide enough vitamin D. Also, sunblock prevents the vitamin from entering the body. To add to the problem, the skin’s ability to process vitamin D weakens as a person ages.
Researchers at Rutgers University in New Jersey are exploring the relationship between vitamin D and dementia. The team recently measured vitamin D levels and cognitive ability in older people. Nutritional sciences professor Joshua Miller led the team. He said cognitive abilities differed among the study subjects. He said tests showed that about 60 percent of the group was low in vitamin D.
1.Which of the following is true about vitamin D?
A. Vitamin D can decrease people’s risk of heart diseases.
B. Vitamin D helps the body fight against cancer.
C. Vitamin D is mainly obtained from the sun.
D. The need for Vitamin D decreases as people age.
2.What does the underlined word “demanding” mean in Paragraph 2?
A. Boring but rewarding.
B. Disturbing and frightening.
C. Disgusting and stressful.
D. Hard and tiresome.
3.What does Paragraph 3 mainly talk about?
A. How vitamin D affects people’s health.
B. Where people get vitamin D.
C. Whether sunlight can produce vitamin D.
D. Why people’s age influences the production of vitamin D.
4.Where can we most probably read the passage?
A. In a travel brochure.
B. In a literature magazine.
C. In a science journal.
D. In a commercial advertisement.
