The fighting against youth smoking since I took office I've done everything in my power to protect our children from harm. We've worked to make their streets and their schools safer, and to give them something positive to do after school before their parents get home. We've worked to teach our children that drugs are dangerous, illegal and wrong. Today, I want to talk to you about the historic opportunity we now have to protect our nation's children form an even more deadly threat: smoking. Smoking kills more people every day than AIDS, alcohol, car accidents, murders, suicides, drugs and fires combined. Nearly 90 percent of those smokers lit their first cigarette before they turned 18. Consider this: 3,000 children start to smoke every day illegally, and 1,000 of them will die sooner because of it. This is a national tragedy that every American should be honor-bound to help prevent. For more than five years we've worked to stop our children from smoking before they start, launching a nationwide campaign to educate them about the dangers of smoking, to reduce their access to tobacco products, and to severely restrict tobacco companies from advertising to young people. If we do these, we'll cut teen smoking by almost half over the next five years. That means if we act now, we have it in our power to stop 3 million children from smoking and to save a million lives as a result. What has the author done in his power? A) To look after our children. B) To clean the street C) To clean our children D) To protect our children from harm.

Many people believe the glare from snow causes snow-blindness. Yet, dark glasses or not , they find themselves suffering from headaches and watering eyes, and even snow-blindness, when exposed to several hours of "snow light". The United States Army has now determined that glare from snow does not cause snow-blindness in troops in a snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of barren snow-covered terrain . So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscles ache. Nature eases this irritation by producing more fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision blurs , then is obscured , and the result is total, even though temporary, snow-blindness. Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark colored objects ahead on which they too can focus. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop scouring the snow-blanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snow-blind or lost. In this way the problem of crossing a solid white terrain is overcome. A suitable title for this passage would be _ . A) nature's cure for snow-blindness B) snow-blindness and how to overcome it C) soldiers marching in the snow D) snow vision and its effect on eyesight

Ques: So far, scientists have named about 1.8 million living species ,and that's just a small part of what probably exists on Earth.With so many plants,animals,fungi,and other organisms covering the planet,it can be tough to figure out what type of spider is crawling up your leg or what kind of bird just flew by. A soon-to-be-launched Website might help.An international team of researchers has announced the creation of a Web -- based Encyclopedia of Life (EOL).The project aims to catalogue every species on Earth in a single,easy-to-use reference guide. To get the encyclopedia started,the creators will use information from scientific databases that already exist.And eventually,in special sections of the site,nonscientists with specialized knowledge will join.Gardeners,for example,will be able to record the dates that their flowers first bloom each year.Bird-watchers will be able to input which birds they've seen and where.The technology for this kind of tool has only recently become available. As the EOL develops, you might find it useful for school projects.The site will have special pages for kids who are studying ecosystems in their neighborhoods.To make sure the encyclopedia is accurate,scientists will review much of the information added to it.People who visit the site will be able to choose to skip pages that haven't been reviewed. Another convenient characteristic of the EOL is that you'11 be able to pick the level of detail you see to match your interests,age,and current knowledge. If you wanted to learn about polar bears for a science class report,for example,you could use the _ setting to get basic information about the animals.On the "expert" setting,on the other hand.you could get much more detailed information about the history,literature,and exploration of polar bears. It now takes years for scientists to collect all the data they need to describe and analyze species.The creators of the Encyclopedia of Life hope that their new tool will speed that process. Keep an eye on _ .Pages will begin to... What is the best title for the passage? A) Exploring Polar Bears. B) Visit Our Website Now. C) How to Do School Projects. D) E-book of Life.

Ques:Rome wasn't built in a day, and the Internet didn't come out of a golden egg. Many of today's creations were not born of people who had creative ideas, but who did not stop at simply having an idea. They took one brick of capital , another brick of knowledge, perhaps a brick or two of family and friends, and built their empires brick by brick. If you want to build an online empire, you cannot settle for simply having a website full of articles, or a website full of pictures--there are already thousands of sites like that, so you need to come up with something new and creative. So if you are starting to build something up, ask yourself: what do you really want to do, and what are you really good at? Believe it or not, you can make money at something that you are an expert in, and you need to know what that is. Remember, having an online empire does not mean that you have to do it alone. You can take _ along with you. Having a friend advertise your services online is a good way to attract more visitors to your empire. Building an online empire, you will have to be prepared to not only come up with creative ideas, but to carry your ideas through. Talk to people who have already succeeded in building their own empires. Talk to people who are struggling. Join a mailing list that will help you get through your struggle to achieve your goal. As you move forward, you will find that you can help other people, and you will have a good many stories to tell--not to mention a lot of money in the bank. If you learn the real secrets of creating a long term stable online business then you will have enough money to retire on. The proverb "Rome wasn't built in a day" applies to a situation where _ . A) expert knowledge is badly needed B) you are short of money at the beginning C) online wealth has to be gained bit by bit D) family and friends will be against your idea
