You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health.There are plenty of "energy drinks" on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!But after a careful check you may find that most energy drinks have lots of caffeine (咖啡因) in them. These drinks are especially 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 makes your heart beat fast. Because of this, the International Olympic Committee has limited( 限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.( )6.

These fears were very real and caused me some uncomfortable moments.Maybe it was the strange way things looked and sounded in my own room at night that scared me so much. There was never complete darkness, but always a streetlight or passingcar lights, which made clothes on the back of a chair take on the shape of a wild animal. Out of the corner of my eye, I saw the curtains(窗帘) seem to move when there was no wind. A very low sound in the floor would seem a hundred times louder than in the day. My imagination (想象) would run wild, and my heart would beat fast. I would lie very still so that the "enemy(敌人) " would not discover me.Another of my childhood fears was that I would get lost, especially on the way home from school. Every morning I got on the school bus right near my home. That was no problem. After school, though, when all the buses were lined up along thestreet, I was afraid that I would get in the wrong one and be taken to some other strange places. On school or family trips to a park or a museum, I wouldn't let the leaders out of my sight.Perhaps one of the worst fears of all I had as a child was that of not being liked or accepted by others. Being popular was so important to me then, and the fear of not being liked was a serious one.One of the processes(过程) growing up is being able to realize and overcome our fears. Understanding the things that scared us as children helps us achieve greater success later in life.( )11.

But what is health? “Health” means eating well, gettin g enough ex ercise, and having a healthy weight. Let’s read the following rules. They can help you stay healthy.(1). Eat a variety of food, especially fruit and vegetables. We all know that eating fruit and vegetables can help us stay healthy, but many of us only eat our favorite food. Remember that we can only get the nutrition (营养) we need by eating different kinds of food, especially fruit and vegetables.(2). Drink water and milk most often.

Every day, you should drink at least three cups of milk, when you are 9 years old or older. Y ou should also try to have less sugary drinks, like soda and coca. They include a lot of sugar. Sugar only includes calories (热量), not important nutrition.(3). Listen to your body. When you are eating, notice how your body feels. When your stomach feels comfortably full, stop eating. Eating too much makes you feel uncomfortable. If you do it too often, it can make you unhealthy and fat.(4). Limit screen time. What’s screen time? It’s the amount of time you spend watching TV, movies and playing computer games.

A group of Americans who taught English in other countries recently discussed their experiences. They decided that miscommunications were always possible, even over something as simple as "yes" and "no".On her first day in Micronesia, an island in the Pacific, Lisa thought people weren’t paying any attention to her. The day was hot. She went into a store and asked, “Do you have cold drinks. The woman there didn't say anything. Lisa repeated the question. Still the Woman said nothing. She later learned that the woman had answered her: She had raised her eyebrows (眉毛), which in Micronesia means "yes".Jan remembered an experience she had in Bulgaria, a country in Europe. She went to a restaurant that was known for its cabbage. She asked the waiter, "Do, you have cabbage today?" He nodded his head. Jan waited, but the cabbage never came.

郑州市2014高考英语阅读理解考前自练题科普知识类阅读理解Federal regulators Wednesday approved a plan to create a nationwide emergency alert(警报) system using text messages delivered to cell phones.Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry’s trade association, CTIA, estimates(估计)more than 48 billion text messages are sent each month.The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvement to the nation’s eme rgency alert system. The act tasked the Federal Communications Commission(FCC) with coming up with new ways to alert the public about emergencies.“The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies,” FCC Chairman Kevin Martin said following approval of the plan.Participation in the alert system by carriers—telecommunications companies—is voluntary, but it has received solid support fro m the wireless industry.The program would be optional for cell phone users. They also may not be charged for receiving alerts.There would be three different types of messages, according to the rules.The first would be a national alert from the president, likely involving a terrorist attack or nat ural disaster. The second would involve “approaching threats”, which could include natural disasters like hurricanes or storms or even university shootings.The third would be reserved for child abduction(绑架) emergencies, or so-called Amber Alerts.The service could be in place by 2010.1. What is the purpose of the approved plan?A. To warn people of emergencies via messages.B. To popularize the use of cell phones.C. To estimate the monthly number of messages.D. To promote the wireless industry.2. The improvement to the present system is in the charge of .A. CTIAB. the Warning Alert and Response Network ActC. FCCD. federal regulators3. The carriers’ participation in the system is determined by.A. the US federal governmentB. mobile phone usersC. the carriers themselvesD. the law of the United States4.
