The weather is getting hotter and you’ll be getting thirstier playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you pour down your throat. Something that looks cool may not be good for your health.
There are plenty of so-called energy drinks on the market. Most of them have an attractive colour and cool name. Their nutrition list also contains various things from vitamins to ginseng. Sounds great!
But after a careful check you may find that most energy drinks contain high levels of caffeine. These drinks are typically aimed at young people, students, busy people and sports players.
Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.
Caffeine raises your heartbeat. Because of this, the International Olympic Committee has limited their use. The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.
Research by Australian scientists has found that many teenagers are affected by caffeine. The results of their survey show that 27 percent of boys aged 8-12 take in more caffeine than their parents.
There are potential health risks linked to energy drinks. Just one can of energy drink can make you nervous, have difficulty sleeping and can even cause heart attacks.
Teenagers should be discouraged from consuming drinks with a lot of caffeine in them, an expert from the Australia Nutrition Foundation said.

Just as the world’s most respected scientific bodies have confirmed that the world is getting hotter, they have also stated that there is strong evidence that humans are driving the warming. Countless recent reports from the world’s leading scientific bodies have said the same thing. For example, a 2010 summary of climate science by the Royal Society stated that: “There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity.”
The idea that humans could change the planet’s climate may be counter-intuitive(与直觉不符的), but the basic science is well understood. Each year, human activity causes billions of tons of greenhouse gases to be released(释放)into the atmosphere. As scientists have known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket.
Of course, the planet’s climate has always been changing thanks to “natural” factors(因素) such as changes in solar or volcanic(火山的)activity, or cycles relating the Earth’s going around the sun. According to the scientific literature, however, the warming recorded to date matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.
Even if scientists did discover another reasonable explanation for the warming observed so far, that would beg a difficult question. As Robert Henson puts it in The Rough Guide to Climate Change: “If some newly discovered factor can account for the climate change, then why aren’t carbon dioxide(二氧化碳)and the other greenhouse gases producing the warming that basic physics tells us they should be?”
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.
1.In most scientists’ opinion, the global warming is mainly caused by ________.
A. solar activity B. volcanic activity
C. the Earth’s going around the sun D. human activity
2.The text is developed by ________.
A. giving typical examples B. following the order of space
C. analysing a theory and arguing it D. comparing and finding differences
3.The underline word “identical” means ________.
A. totally different B. exactly the same
C. extremely important D. relatively independent

This spring, you may be fortunate enough to have good weather, a small piece of earth and the energy, enthusiasm and inspiration to plant a garden. There is nothing better to shake off the boredom and dullness of winter than to dig in the earth, plant some seeds and watch them grow. A small garden can produce something extra fresh for dinner, flowers for the table and a feeling of accomplishment. It is work, but it is ever so rewarding.
What about your life garden? Just as a beautiful garden is a work in progress, so is the garden in your mind. It takes conscious effort, planning, constant nurturing(培育) and weeding to grow a garden. What have you planted? What have you allowed to take root? Is your life the out-picturing of a well laid out garden or a jumble of plants, trees and weeds whose seeds were blown your way and took root?
We have all heard phrases like "sowing seeds of doubt", or "seeds of discontent." We can make a conscious choice whether to allow them to take root in our lives or cast them out of our garden. Negative energy and words, like weeds, will spread quickly if left unchecked. Find a good "weed killer"-a book, an inspirational story, a positive statement-to help you get rid of the thoughts that ruin the beauty of your garden.
Plant as many seeds of joy and beauty as you can-in your own life and in the lives of the people with whom you live and work every day. Grow a gratitude garden, a peace garden and a dream garden. Tend to them daily. If you give them time and energy, you will have a rich harvest of success, happiness and peace of mind.
1.Why does the author tell us the benefits of growing a garden?
A.To ask us to love gardening. B.To show his love for gardening.
C.To lead in to the topic of the text. D.To show what a life garden is like.
2.In what way is our life garden similar to a beautiful garden?
A.It is in change all the time.
B.It can make us happy and grateful in life.
C.It needs our conscious effort and constant care.
D.It is full of both positive energy and negative energy.
3.Why does the author compare negative energy and words to weeds?
A.They are a natural part of life. B.They are difficult to remove.
C.They are often left unchecked. D.They need to be removed before they spread.
4.Which of the following can be regarded as a weed killer?
A.Reading a dull book. B.Relieving our discontent.
C.Having positive self-talks. D.Pulling weeds in the garden.
