题目内容

All my friends at school smoked(吸烟). My dad smoked. He didn't want me to smoke but my friends kept saying I was stupid. They asked when I was going to grow up. So I started smoking when I was sixteen and after a month I couldn't stop. But two years later I could feel what smoking was doing to me. I couldn't run far, and I coughed( 咳嗽 )every morning. I got very ill and decided to stop. It wasn't easy, but now I've done it, and I feel better. Now I have money for other things.

If you smoke, you are twice likely to get a heart attack(心脏病). And the more you smoke,the earlier the heart attack is likely to get. For example, a 50-year-old who smokes more than 20 cigarettes a day is four times more likely to have heart disease than a non-smoker of the same age.

What does smoking do to the heart? First of all, it makes the heart beat faster and increases the blood pressure(血压) .The cigarette smoke also reduces(减少) the amount of oxygen(氧气) in the blood. Consequently, the heart has to work harder, with less oxygen Finally, your arteries(动脉) will narrow(变窄) faster if you smoke.

So if you want to reduce your chances of getting heart diseases, the answer is easy - not to smoke. Don't copy your friends and other people who smoke. If you smoke find out how to stop.Stopping isn't easy, but you' ll be healthier

Google is a company's name, but it has also grown into a verb that means, "to do an Internet search." Now everyone and their grandma know what it means to Google it. You know that you're doing something big when your company name becomes a verb.

Google wasn't the first company to invent their product. Lycos released their search engine in 1993. Yahoo! came out in 1994. AltaVista began serving results in 1995. Google did not come out until 1998. That is a major head start in the fast moving world of tech. So how did Google overtake(超过)their competitors who had such huge leads in time and money? Maybe one good idea made all the difference.

There are millions of sites on the Internet. How does a search engine know which ones are relevant to your search? This is a question that great minds have been working on for decades. To understand how Google changed the game, you need to know how search engines worked in 1998. Back then most websites looked at the words in your query(查询).They counted how many times those words appeared on each page. Then they might return pages where the words in your query appeared the most. This system did not work well and people often had to click through pages of results to find what they wanted.

Google was the first search engine that began considering links. Links are those blue underlined words that take you to other pages when you click on them. Larry Page, cofounder of Google, believed that meaningful data could be drawn from how those links connect. He was right. Google's search results were much better than their rivals'(对手).They would soon become the world's most used search engine.

It wasn't just the great search results that led to Google becoming so well liked. It also had to do with the way that they presented their product. The home pages of most other search engines were filled with all kinds of things. But Google's homepage was, and still is, clean. There's nothing on it but the logo, the search box, and a few links. In fact, when they were first testing it, users would wait at the home page and not do anything. When asked why, they said that they were "waiting for the rest of the page to load". But the fresh design grew on people once they got used to it.

These days Google has its hands in everything from self-driving cars to helping humans live longer. Though they have many other popular products, they will always be best known for their search engine. Not only is Google search engine a fantastic product, it is a standing example that one good idea(and a lot of hard work)can change the world.
