HOW TO GET MORE SLEEP
Many studies warn that not having enough sleep may lead to serious health problems, affecting our daily life, work and study. You’ve probably known this for long, yet you still don’t get a full night sleep due to an incredible work schedule. So what can you do to make more time for sleep, and get a better night’s rest overall?
• Invest in a better-quality mattress. If you’re sleeping on a years-old, worn-out mattress(床垫), it’s no wonder why you wake up feeling tired in the morning. 1. With a new mattress that’s better suited to your sleeping habits, you’ll get to sleep faster and stay asleep consistently.
• 2. There are many habits that can affect how much sleep you get, including how much caffeine you consume throughout the day (and when you consume it — even a few hours before bedtime can interfere with sleep), whether or not you physically exercise, and how long you spend staring at a digital screen before bed.
• Take a closer look at your schedule.3. In Western culture, there’s a lot of pressure to fill up our schedules to seem important and socially integrated, so your daily activities might have some faults or unnecessary tasks that can be skipped or delayed. 4.
Sleep is even more important than you probably realized, but it’s entirely within your power to reshape your sleeping habits for good. Make sleep your first priority, scheduling time for it the way you’d schedule a meeting, and work the rest of your schedule around it. 5.
A.Watch your habits.
B.Some habits contribute to a good night’s sleep.
C.Without enough sleep, you could take more risks in your life.
D.A new mattress can be a big investment, but it’s almost worth the money.
E.Draw a line between professional and personal time, and make sleep a higher priority.
F.If you feel like you’re too busy to sleep, consider taking a second look at your schedule.
G.In time, it will become the new routine, and you’ll improve your health and productivity.
Tenzing left his home when he was ten to work and help his mother，who was looking after their 2-acre ancestral farm after his father’s death. He did temporary jobs for the first few years and then joined a Malaysian construction firm，where he learnt to drive，repair machines, work on the Internet and even speak English fluently.
“In those 13 years，I learnt everything—driving, mechanic work，and how to set up a small factory. This made me gain much confidence to do almost all jobs,” says Tenzing.
However, as his mother was getting older, on December 12, 2006, Tenzing returned to his hometown in Assam. Having visited several farms, he came to know that tea could be easily exported and many tea companies were buying tea; so he also decided to grow tea on his farm. But as his family had never grown tea，he had no idea how to do it.
Being a layman (外行）in this field, Tenzing went to meet with many tea experts and followed their instructions. But whenever he sprayed pesticide (农药）on his farm, he’d get a headache and feel indisposed. So he started looking for alternatives, Tenzing did his research online and finally in 2007, he connected with people from a Canadian non-governmental organization and invited them to his farm, where they trained him. Thus, Tenzing started growing tea organically.
Today Tenzing has 25 acres of land, in which 7.5 acres is used for tea planting, and he grows almost all types of fruits and vegetables. His success inspired many, and farmers from other parts of the country also started coming to his farm to learn organic farming. He has trained about 30,000 farmers so far. Every year almost 100 tourists visit his farm from various parts of the world like the UK, Australia, Germany, etc.

C. He received much formal education. D. He had great learning ability.
2.Why did Tenzing want to grow tea on his farm?

My parents both left school at 14. They could read and write, but except for a quick look at the daily newspaper, reading and writing didn't play a big part in their lives. There were very few books in the house. When I was only 14 years old my father gave me an important letter that he'd written to the bank and asked me to check it for grammar and spelling mistakes. And there were quite a lot. He never wrote letters or postcards or even Christmas cards. So when he had to write he wasn't comfortable or confident. Does that mean that my father had a ‘low level of literacy (读写能力)’? I don't think so.
There are lots of different definitions (定义) of literacy. Some experts define it as having the reading and writing skills that you need to be independent in your everyday life. So, for example, if you can read instructions, write a cheque, fill in a form — anything that you need to do in everyday life — then you are ‘functionally literate’.
If you live in a society where most people are literate then you will feel ashamed and avoid situations in which you have to read or write. A friend's father finally admitted to his family that he couldn't read when he was 45 years old. He had bought the newspaper every day and pretended to read it.
Being illiterate can have a big effect on people's lives. Worldwide statistics show that literacy problems are associated with poverty and a lack of political power. More women than men are illiterate. Illiterate people have worse health, bigger families and are more likely to go to prison. So literacy campaigns must be a good thing. But don't forget that an illiterate person, or someone with a low level of literacy, isn't necessarily stupid or ignorant (无知的) — and may not be unhappy at all. Knowledge and wisdom isn't only found in writing.
1.What do we know about the author's father?
A. He read a lot. B. He rarely wrote.
C. He couldn't write. D. He bought many books.
2.What does the author say about “functionally literate” people?
A. They are usually mind readers.
B. They can read between the lines.
C. They are mainly dependent on others.
D. They are able to read and write to survive.
3.Why did the friend's father buy the newspaper regularly?
A. To keep his secret.
B. To be fashionable.
C. To enjoy the daily news.
D. To further his study
4.What is literacy irrelevant to according to the author?
A. Health. B. Poorness.
C. Influence. D. Happiness.
With rapid advances in medical science, cloning is slowly but surely looking like it could be in our near future. However, is it really an option that should be considered as a way to extend human life?
Reproductive cloning may help human families gain children, but there's also a benefit for the animal world. It brings hope to people eager for children but unable to have their own or adopt. It can also bring about the recreation of species that have long since died, allowing scientists to fully study the species as a living creature instead of simply looking at images or bones.
Many believe that cloning can be used to replace failing organs. This will reduce the waiting list for organ donations and allow more people to be saved. Not only that, but because the organ is, in fact, your own organ, there would be less chance of rejection.
Cloning could prove helpful in genetic research. Using cloning technologies, genetic researchers would have a better understanding of the composition of genes and the effects of genetic constituents (成分) on human characters. There's also the possibility of changing genetic constituents in cloned humans, and cloning could help fight genetic diseases.
While the cloning of body organs can help extend human life, it could also cause a lot of malpractice (玩忽职守). Along with the ability to clone desired characters, there could be the possibility of people deliberately reproducing undesired characters. This could lead to a rise in malpractices within society.
Cloning involves a process of creating identical genes. As such, there would be a lack of diversity in humankind. Scientists believe this lack of diversity will lower the human race's ability to adapt.
Whatever your view on cloning may be, studies show that the clone would in fact not be completely identical to the original just as twins are not completely identical. Though they might look alike, twins have different personalities and enjoy different things. The same could be said of clones. Even if technology were created in which your memories and thoughts could be transmitted (传送) to the clone, your clone would still be a different person.
1.What good might reproductive cloning bring?
A. It may help improve human well-being.
B. It could contribute to the rising birthrate.
C. It could help animals survive deadly diseases.
D. It may enable scientists to better study extinct species.
2.According to the text, cloning can also be used for .
A. organ transplant
B. solving the aging problem
C. infectious disease treatment
D. constructing a gene database
3.What's one problem cloning may cause?
A. Great diversity.
B. Individual security risk.
C. Increased improper conduct.
D. Serious personality disorder.
4.Why are twins mentioned in the last paragraph?
A. To stress twins' similarities.
B. To show twins are quite common.
C. To carry out deeper research on twins.
D. To better illustrate what a clone will be like.
