Summer has finally arrived, which means kids are bound for the outdoors. It can be exciting for kids and parents to have a great opportunity to go swimming, picnicking or on adventures. This time of year is also a dangerous time of year as almost half of all injury-related deaths in children occur between May and August. Whether it be in the pool, on bike, out in the sun or in the backyard is always important. Here are some tips to keep the family safe over the summer.

Water Safety

At this time of year, drowning deaths among children skyrocket（飞涨） compared to the rest of the year. Never leave your child alone in the water, even in shallow water. A child can drown in as little as one inch of water. Enroll your children in swimming lessons. Some swim schools offer class for children as young as 6 months.

Sun Safety

We are fortunate enough to live in the Sunshine State, where sun shines year-round. But with all the time you and the kids will be spending outdoors this summer, it’s important to protect yourself. Make sure to use a widely-used sunscreen(防晒霜) that blocks both UVA and UVB sunlight. Cotton clothing has an estimated SPF of only 6, so even if your kids are going out wearing T-shirts and shorts, make sure they are covered up.

Bike Safety

Nothing says summer like a nice neighborhood bike ride. But bikes are not toys and can certainly cause injury. Don’t forget to always wear a helmet. Head injuries are reduced by 85 Percent when riders wear a helmet and other safety equipment like knee and wrist pads. It’s estimated that 75 percent of bicycle-related deaths could have been prevented with bicycle helmets. When riding on the street, make sure kids understand all riding hand signals, ride with the traffic flow and stay as far right as possible.

1.Summer is called a dangerous time because children .

A. are easily injured

B. enjoy staying in the sun

C. want to learn swimming

D. refuse to accept advice

2.What can be learned from the passage?

A. Kids only need to wear T-shirts and shorts.

B. Bikes, like toys, seldom lead to injury.

C. Some swim schools offer children class for free.

D. Deaths from drowning increase suddenly in summer.

Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University’s School of Life and Health Sciences. The findings suggest there may be some scientific basis of the "5-second rule" — the belief about it being fine to eat food that has only had contact with the floor for five seconds or less. Although people have long followed the ‘5-second rule’, until now it was unclear whether it actually helped.

The study, undertaken by final year Biology students and led by Anthony Hilton, Professor of Microbiology at Aston University, monitored the transfer of the common bacteria from a variety of indoor floor types as carpet, cement floor to toast, pasta, biscuit and a sticky sweet when contact was made from 3 to 30 seconds. The results showed that: time is a significant factor in the transfer of bacteria from a floor surface to a piece of food, and the type of flooring the food has been dropped on has an effect, with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from cement flooring surfaces to moist foods making contact for more than 5 seconds. Professor Hilton said, "Consuming food dropped on the floor still carries an infection risk as it very much depends on which bacteria are present on the floor at the time."

The Aston team also carried out a survey of the number of people who employ the ‘five-second rule’. The survey showed that: 87% of the people surveyed said they would eat food dropped on the floor, or already have done so. 55% of those that would, or have eaten food dropped on the floor are women. 81% of the women who would eat food from the floor would follow the ‘5-second rule’. Professor Hilton added, "Our study showed that a surprisingly large majority of people are happy to consume dropped food, with women the most likely to do so. But they are also more likely to follow the ‘5-second rule, which our research has shown to be much than an old wives’ tale."

1.According to the passage, which of the following is true?

A. A toast dropped on the carpet is easier to be polluted than that dropped on the cement floor.

B. A sticky chocolate dropped on the carpet is easier to be polluted than that dropped on the cement floor.

That woman carried a new blanket (毛毯) over her arm. Wordlessly, she gave it to me.

“Is it finished?” I asked.

She shook her head. “No. It is ready,” she replied. I handed her the money and took the blanket.

“It is beautiful, so skillfully woven (编织),” I said to my mother. “But what did she mean when she said it was not finished? How can it be ready if it is not finished?”

“I will tell you later,” my mother said, “but first I will take you to the Navajo(纳瓦霍) village.”

We went down to the village. A group of young men were making sand pictures. We walked through the whole village, watching the different things the people were doing.

It was not until that evening that my mother finally explained the Navajo woman's words.

“Did you notice anything about the things the people were making?” my mother asked.

“What should I have noticed?” I looked at her and asked.

“Each thing the Navajo make has one small part that is not complete. The designs in their sand pictures are often not perfectly done, for example —the line of a circle may not quite close. If you look carefully at your blanket, you will probably find a stitch (一针) missing.”

I took the blanket off, but it looked as perfect as any design could be. Then suddenly, I noticed that sure enough a stitch was missing!

“But why do the Navajo intentionally leave some tiny part unfinished?” I asked.

“They believe that when anything is completed or finished, it means the end has come — it will not be perfect until then. Then too, with a circle, they believe that they must leave a pathway for the bad spirits to run away and the good spirits to come in. So, often, they do not make the line close.”

It was a quiet village in which there was a military camp(军营).It was far from the towns and cities and there were some high mountains around. Of course it was a good place for training the new soldiers. But it was difficult for the young men to go outside. Mr White, an officer of forty, was strict with them and he hardly let them leave the camp.

Once Mr White was ill in bed. He couldn’t work and a young officer, Mr Hunt began to train the new soldiers instead of him. He knew the young men well and let nine soldiers go to the nearest town to have a holiday. But night fell and none came back to the camp. He was worried about it and stood at the gate. It was five to twelve when Mr Hunt decided to go to the town and see what was happening to the young men. He started the car quickly and set off. At that moment the nine soldiers came back. It seemed they drank wine. Of course they found the officer was angry.

“I’m sorry, sir,” said the first soldier. “I left the town on time. But something was wrong with my bus on my way here. I had to buy a horse and made it run fast. Bad luck! It died and I had to run back.”

And the other seven soldiers said they were late for the same reasons. It was the last soldier’s turn. He said, “I’m sorry, sir. I got on a bus on time, but…”

Having heard this, the officer became even angrier and stopped him at once. He called out, “If you say something was wrong with your bus, I’ll punish you at once!”

“No, no, sir,” said the young man. “My bus was all right, but the horse died!”

It was dangerously cold. A few drivers slipping and sliding off the road and back on again had cut deep ruts（车辙）in the mud. And the ruts became frozen solid. The drum of our truck’s aging engine worried us.

Trees and bushes heavy with snow bent to form an icy tunnel. We inched along the scary route as Howard grasped the steering wheel（方向盘）tightly, trying to keep the truck in the ruts. We were now riding through a nightmare with no going back. I kept praying the truck would not quit.

However, the engine’s coughing grew worse. We came to a bumping stop. Hot tears ran down my face. We noticed a small house off in the distance. “I will go for help.” Howard’s words ruined my common sense and panic took over. We would take the children — we would walk to that house together!

But the snow was deep, and our two children, asleep in the cab, were too heavy to carry. My husband convinced me to let him go alone. If no one was home or they didn’t answer the door, he would come back and we’d try to hike out to a main road. For now, it was safer in the truck. I wish I could say I have faith, but when he walked away, I was mad at the world.

It seemed as if hours had passed before I heard a familiar voice and a kind laugh of another man as they approached in the snow. The older fellow invited us to go up to the house where his wife was waiting. Two wide-awake kids moved across the seat, ready for adventure. Their voices and laughter carried in the cold night air. When we finally got close, a cheerful woman opened the door. Warm air and the smell of hot buttered popcorn and chocolate drew us in.

Relieved, my prayers were heard!

If you feel sleepy every morning, don't blame yourself. Your work schedule could be to blame.

A recent research shows that, for many of us, our work schedules do not agree with our natural body clocks—and experts are urging employers to take notice.

“When work schedules agree with people's natural sleep patterns, they produce higher quality and more creative work because they are more focused, less stressed and generally healthier. The opposite is also true—when employees are sleep deprived, they are more likely to make major mistakes and suffer from workplace injuries，” said Christopher Barnes, a management professor from the University of Washington.

“But it's not just about the amount of sleep you get. Whether you can be productive at 8 a．m. depends on your own body. Human beings each have an internal body clock，” said Till Roenneberg, a professor at Ludwig?Maximilian University in Munich. And that clock can differ greatly depending on the person.

“It's like feet，” said Roenneberg. “Some people are born with big feet and some with small feet, but most people are somewhere in the middle.”

Many companies start the work day at 8 a．m. or 9 a．m., putting their work schedules in disagreement with their employees' body clock. That mismatch, along with the pressure from work at all hours of the day and night, means that many people suffer from “social jetlag”. In other words, their bodies are always in the wrong time zone. He estimates that more than 70% of people get up earlier than they should.

“There is an old saying that sleep is for the weak，” said Roenneberg. “But I do feel like it doesn't help to have shortened sleep.”

1.According to the author, many people feel sleepy in the morning because________．

A. they start to work too early B. they are not in good health

C. they have no interest in their work D. they stay up too late the night before

2.What does Christopher Barnes mainly tell us?

A. The influences of lack of sleep.

B. The possible causes of poor sleep.

C. The useful ways to improve our sleep.

D. The connection between sleep and work performance.

3.By mentioning people's feet, Roenneberg intends to tell us ________．

A. people are born with feet of different sizes

B. people's body clocks differ from person to person

C. it is the most important to wear shoes of the right size

D. it is most important to obey our natural body clocks

4.Which of the following does the author agree to?

A. Sleep is for the weak. B. The early bird catches the worm.

C. Plenty of sleep contributes to good work. D. The more you sleep, the less work you can do.
