Have you ever felt so tired after staying up for a night that even coffee doesn't give you the energy that you need? You may have an energy drink, but the benefits of drinking one arc heavily outweighed by the risks.

In the past years, more and more studies have found the deadly effects of energy drinks on our bodies. The sugar, caffeine and energy supplements (补充)in energy drinks make up a deadly mixture of ingredients that can affect your heart function and send you to the hospital!

A study by the University of Bonn, Germany found that frequent consumption of energy drinks can greatly change the way our heart functions. The study went on to say that consuming energy drinks often causes significantly increased heart contractions in adults, which has the potential of putting you at risk for irregular heartbeats.

It is possible that many people are unconscious of the alarming side effects of energy drinks because of the way they are labelled. Most energy drinks contain between 80 milligrams to over 350 milligrams of caffeine, sugar and energy supplements. When an energy drink is marketed as a diet supplement, it may be distributed without a "nutrition facts" label, which would show the harmful supplements that are in the drink. However, even if energy drinks are Food and Drug Administration (FDA) approved, they don’t have to show the number of supplements.

Energy drinks may be widely available but they aren't the healthiest or safest choice for your body. To stay naturally energized, get organized and stay on top of your work so that you aren't having to stay up all night to complete assigned tasks. If you'd like a natural energy boost, you could make time for a short workout, which will give you all of the energy you need!

1.Which of the following is the side effect of the energy drinks?

A.Making people thinner.

B.Making people's heart bigger.

C.Making people run a risk of falling ill.

D.Making people suffer from heart attack.

2.Why are many people unaware of the harmful effects of energy drinks?

A.Because they don't read the label carefully.

B.Because FDA thinks they are healthy drinks.

C.Because the harmful materials are not labelled.

D.Because factories of energy drinks lie to drinkers.

3.What is the last paragraph mainly about?

A.The benefits of doing exercise.

B.The better choice of right drinks.

C.The way to have enough energy.

D.The effects of energy drinks.

4.What is the best title for the text?

It's the most popular drink worldwide. According to the British Coffee Association, approximately two billion cups of coffee are consumed every day. But after the beans have been picked, roasted and brewed, the grounds（渣子）are often treated as waste. With the environment and resource consumption such hot topics at the moment, wouldn't it be great if we could reuse this waste to make something useful?

The company OCHIS produces sunglasses. Max Havrylenko, founder of the company, was searching for an alternative material to plastic. He wanted to "solve the problem of plastic use and overconsumption so as to create a greener world," he told the Guardian. OCHIS heats the grounds with vegetable oils, forming a bond. These are pressed into plates which are durable and flexible. These are then cut into the arms and frames of the glasses. "Don't worry," he says, "They won't dissolve（溶解）in the rain."

Rosalie McMillan, a London jeweler, uses recycled coffee grounds along with gold and silver to make handcrafted jewelry. Mixed with oils, the coffee is then subjected to heat and pressure to create a compound she calls "Curface". Her website says it has a "beautiful surface quality and texture" with similar properties to hardwood.

What about a coffee cup made from them? Kaffeeform is a German-based company that transforms used grounds and renewable plant-based raw materials into a durable composite. This is shaped into a variety of containers and polished and finished, ready to be sold. So, you can drink your coffee from a cup made of coffee.

And it doesn't stop there. Even without a factory, you can make use of coffee grounds. They make excel-lent fertilizer（肥料）. You can highlight something against them, or mix them with water to make a brown-toned paint. And the list goes on. So next time you finish your morning cup, lake a while to think again.

1.The first paragraph is mainly written to introduce 　　　　 .

A.how people treat coffee grounds B.annual consumption of coffee

Mya Le Thai is a scientist studying at the University of California, Irvine. She recently discovered a process that may result in batteries that last forever. Thai said she had been discouraged that the batteries for her wireless devices degrade. Over time, they fail to charge fully.

Thai did not like to have kept her wireless laptop connected to an electrical outlet. She decided to do something about that problem.

At first, she and her team thought about inventing a new battery. But as they experimented, Thai discovered something that might permit lithium-ion(锂离子) batteries to last forever. Lithium-ion batteries power most wireless devices. Over time, the batteries lose the ability to hold a charge. Most of these batteries have a life span of about 7,000 charging cycles before they die.

One of the reasons lithium-ion batteries degrade is their use of nanowires(纳米线) to carry electricity. Nanowires are extremely thin. A human hair is thousands of times thicker, for example. Nanowires are extremely efficient carriers of electricity, which makes them useful in batteries. But Thai said their thinness also makes them weak. “Nanowires break over time,” she said. “That's why they lose capacity(能力).”

But, Thai had a theory: The nanowires might last longer if covered with a material. She and the team tested her theory. The team tried many coverings for the wires. PMMA was one of them. The nanowires were coated with PMMA and cycled through charges 200,000 times. The PMMA coated nanowires showed no evidence of damage. The results suggest that batteries could last forever, without losing charging ability.

Thai hopes to continue her research to understand why this material works so well and to see if any other material could create better results.

“It's kind of cool,” she said, “I'm really glad people are showing interest in my work and not just in the work itself, but also in technology and energy.”

1.What caused Thai to do research on the batteries?

A.Weak power of the batteries. B.Her habit to use her computer.

C.Inconvenient use of batteries. D.Her preference for batteries.

2.What's the disadvantage of lithium-ion batteries?

A.They have a limited service life. B.They need charging very often.

C.They are not quite dependable. D.They are easy to break down.

3.Why did Thai try covering the nanowires with a certain material?

A.To convey more electricity. B.To make them a thicker cover.

C.To make them much safer to use. D.To protect them from being damaged.

4.What can probably be a suitable title for the text?

A.Batteries Would Work Without Recharging

B.Lithium-ion Batteries Might Come to an End

C.Batteries Lasting Forever Could Be Near Soon

D.Batteries Would Be Replaced By A New Power

It uses fire wall barriers to help limit the spread of fire, which will protect the buildings from burning without damaging them.

5.

Some countries have installed fire protection equipment but can't take action soon enough. Given this, the Brazilian government completed a project to adopt advanced electrical waning system and to inform firefighters of fires in no time, which would urge them to take immediate action to stop the fire spreading.

A.Take action quickly.

B.Improve the protection equipment

C.Sadly, it was not a specific example through the years.
