Walking in any high school during the first class in the morning, you will find many students are struggling to stay awake.

“They’re sitting in the classroom, but their heads are at home on the pillows,” said a teacher from a high school.

Don’t blame them; blame the clocks in their brains. A research suggests that biological clocks make teens stay up at night and sleep in the morning.

During the first several weeks of school, students are more likely to lack sleep. In the holidays, students can sleep eight hours a night, but during the school days, they sleep only about six hours on average. Students lose 10 hours’ sleep a week. This may affect their school performances and leads to poor health.

   Scientists in the US did research to reset teenagers’ biological clock to help them fall asleep earlier. They found the brain can produce a chemical that helps sleep. But it comes out only in the dark. So they use a special light in the classroom to try to force a reset of the students’ biological clock.

The research failed in the end. So some schools in the US tried to reset their school time from 7:25 a.m. to 8:30 a.m. The results seemed to be good.

One day when Jack was walking in the park, he saw a woman, who lived a few miles away, sitting on a bench with a dog beside her. The dog was looking up at the woman.
Jack walked up to the woman and said, "Hello, Sue, how are you? May I sit and talk with you for a while?" "Of course, please sit down," Sue said. Jack sat down next to Sue on the bench, and they talked quietly together. The dog continued to look up at Sue, as if waiting to be fed.
"That's a nice dog, isn't he?" Jack said, pointing at the animal.
"Yes, he is. He's handsome. He's a bit of a mixture, but that's not a bad thing. He's strong and healthy."
"And hungry, "Jack said." He hasn't taken his eyes off you. He thinks you've got some food for him."
"That's true, "Sue said." But I haven't."
They both laughed and then Jack said, "Does your dog bite?"
"No, "Sue said, "He's never bitten anyone. He's always gentle and friendly."
Hearing this, Jack decided to hold out his hand and touched the animal's head. Suddenly it jumped up and bit him.
"Hey!" Jack shouted." You said your dog didn't bite."
Sue replied in surprise, "Yeah, I did. But this is not my dog. My dog's at home."
【小题1】The dog looked at the woman because ___.

High-quality customer service is preached(宣扬) by many ,but actually keeping customers happy is easier said than done. Shoppers seldom complain to the manager or owner of a store, but instead will alert their friends, relatives, co-workers, strangers-and anyone who will listen. Store managers are often the last to hear complaints, and often find out only when their regular customers decide frequent their competitors, according to a study jointly conducted by Verde group and Wharton school.
“Storytelling hurts the boss and entertains consumers,” said Paula Courtney, President of the Verde group.” the store loses the customer, but the shopper must also find a replacement.” On average, every unhappy customer will complain to at least four other, and will no longer visit the specific store for every dissatisfied customer, a store will lose up to three more due to negative reviews. The resulting “snowball effect” can be bad to bosses.
According to the research, shoppers who bought clothing met the most problems. ranked second and third were grocery and electronics customers. The most common complaints include filled parking lots, cluttered (塞满了的) shelves, overloaded racks, out-of-stock items, long check-out lines, and rude salespeople. During peak shopping hours, some retailers solved the parking problems by getting moonlighting local police to work as parking attendants. Some hired flag wavers to direct customers to empty parking spaces. This guidance eliminated the need for customers to circle the parking lot endlessly, and avoided fight between those eyeing the same parking space.
Bosses can relieve the headaches by redesigning store layouts, pre-stocking sales items, hiring speedy and experienced cashiers, and having sales representatives on hand to answer questions.
Most importantly, salespeople should be diplomatic and polite with angry customers. “Retailers who’re responsive and friendly are more likely to smooth over issues than those who aren’t so friendly.” said Professor Stephen Hoch. “Maybe something as simple as a greeter at the store entrance would help.” Customers can also improve future shopping experiences by filling complaints to the boss, instead of complaining to the rest of the world. Bosses are hard-pressed to improve when they have no idea what is wrong.
1. Why are store managers often the last to hear complaints?
A. Most customers won’t bother to complain even if they have had unhappy experiences.
B. Customers would rather relate their unhappy experiences to people around them.
C. Few customers believe the service will be improved.
D. Customers have no easy access to store managers.
2. What does Paula Courtney imply by saying “ … the shopper must also find a replacement” (Line 2, Para. 4)?
A. New customers are sure to replace old ones.
B. It is not likely the shopper can find the same products in other stores.
C. Most stores provide the same
D. Not complaining to the manager causes the shopper some trouble too.
3. Shop owners often hire moonlighting police as parking attendants so that shoppers_____
A. can stay longer walking in the store  B. won’t have trouble parking their cars
C. won’t have any worries about safety  D. can find their cars easily after shopping
4. What contributes most to smoothing over issues with customers?
A .Manners of the salespeople   B. Hiring of efficient employees
C. Huge supply of goods for sale   D. Design of the store layout.
5. To achieve better shopping experiences, customers are advised to _________.
A exert pressure on stores to improve their service
B. settle their problem with stores in a diplomatic（外交）way
C. voice their dissatisfaction to store managers directly
D. shop around and make comparisons between stores

An enjoyable trip

On October 28th, we began our exciting trip to the world-famous sand island—Fraser Island, which is said to be the world largest sand island and it is one of the world cultural heritages (遗产). We were really amazed by the spectacular view there.

The road to the island is really tough and bumpy. The bus driver, who was also our guide was a very strong man. He was optimistic (乐观的) and helpful. I found he was all smiling on the way though the ride was not very smooth. We stopped for several times because the cars in front of us were blocked by sand. The road was completely sand about 50 centimeters high. We were thrown back and forth like taking a rollercoaster (过山车). All of us couldn’t help laughing when we were shaken from side to side. It took us more than an hour to arrive there. I guess this road is one of the most impressive things.

The beach is so wonderful and terrific! This was my first visit to the seaside. The broad sea made me speechless. We were really thrilled by the amazing view. We couldn’t stop taking so many pictures. The bus ran along the beach with the sea water on one side and bushes on the other side. The view outside the bus was really fantastic! The driver told us there were dingoes (野犬) in the bush. When we were sitting on the bus, we kept on searching the faraway bush for a dingo. Unfortunately, we didn’t see one.

The lake is the next destination we went to. This lake which is ringed by white sand beaches lies peacefully on the hill, which is 18 meters above the sea level. The crystal clear water from the rainfall is sparkling (闪光). Male students jumped into the lake without taking off the clothes. They played with water like small children. Nowhere else in the world can you find such a wonderful fairly land.

The forest is the last place we visited. Those towering rainforests grow on sands. There are many varieties of species. Some trees are so tall and have a history of 500 years. Some gum trees are quite strange because their barks (树皮) fall. The driver told us that this was because they wanted to protect themselves from worms or fires. This forest is home to many animals. We could hear bird singing when we were walking in the shade from the trees.

The tour to Fraser Island makes a deep impression on us. It provides us magnificent views. It is well worth a visit.

You maybe surprised to learn that one of the best steps you can take to protect your health is to step outside and spend some time in the grass, dirt and water．

       Our ancestors enjoyed the healing power of nature , and now scientists are starting to catch up．According to research in recent years, just having a view of nature has been shown to improve hospital patients'  recovery and reduce illness rates among office workers．Also, exposure （曝露）to wildlife, horseback riding, hiking, camping and farms can be helpful for a variety of health conditions in adults and children．

       Much of this type of research is focusing on children, and in fact an entire movement has quickly developed to connect kids with the healing power of nature．

       Obesity （肥胖）．Rates of childhood obesity have grown sharply in recent years, and this is partly because of reduced outdoor activity time．Increasing the time students spend learning about nature, both in and outside the classroom, would help solve this problem．Such lessons are often more attractive for students and often lead them to become more active outside．

       Attention deficit hyperactivity disorder （ADHD）  （注意力缺失症）．Exposure to ordinary natural settings （环境） in the course of common after-school and weekend activities may be effective in reducing attention deficit symptoms in children．Participation in green activities —such as nature walks—helped ADHD patients from a wide range of backgrounds to stay focused and complete tasks．

       Stress．Access to nature, even houseplants, can help children cope with stress．

       Depression  and  seasonal  emotional  disorder．Major  depression requires medical treatment, but physical activity, especially outdoors, can help ease symptoms．For your average case of winter blues, experts suggest spending time outside every day and, if possible, taking the family to a sunny vacation spot in mid-winter．
