Added Costs

Every time you have your cell phone with you, it could ring and interrupt what you are doing. While it is convenient to keep your phone with you when you are away from home, it also leaves you open to calls from your mother, your boss, or anyone that knows your phone number. This may lead some people to feel like they have less privacy than before.

I took our foreign teacher Mr. Brown, he came to China for the first time, to the Great Wall last weekend. Having told about the history of the Great Wall, he was amazing at this world wonder. He was fascinated by the beauty of the Great Wall, so I took photos of himself, which would be a good memory for him. At the top, there was an activity about environmentally protection. Mr. Brown was so interested in protect the environment that he was eager to join in them. Both the Great Wall or the warm-hearted Chinese people deeply impress him. He decided to visit more place of interest when free.

   Smoking is harmful. But as soon as you quit the habit, everything will be OK, right? Wrong.

New research has found that even if you give up smoking, the damage it has done to your genes will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed--a number that is one-third of known human genes.

According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.

When you stop smoking, a lot of these genes will return to normal within five years.

This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years, It’s almost like leaving a footprint on wet cement (水泥)----it will always be there, even when you’ve walked away and when the cement becomes dry.

Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

My cousin George and I went on a trip to my uncle yesterday. We were riding along a hillside while suddenly some big stones were rolled down and knocked us off our bikes. George’s legs got seriously injure and so did mine. We couldn’t move a bit. Lucky，I saw some farmers ahead. Waved our hands，we cried for help. On hearing us，they run to the spot as fast as they could. Thanks their help，we were all sent to a nearby hospital and received medical treatment in time. Although we don’t know their name，we feel they are like our dear big brothers and sisters.

As the saying goes, time is money. And in my opinion, time is even precious than money. Why? Because when money is spent, we still have a chance to earn them back. But when time is wasting, we can never get it back. There is no doubt whether time is very limited, and even a minute is of great value. We should make fully use of time to do what should be done. It’s the pity that a lot of people still didn’t appreciate the value of time. They are wasting their time doing nothing of useful. We should form the good habit of race against time and make a difference in our world.
