Nowadays, pets become so close and friendly to our human-beings that more

and more people enjoy keeping them. Pets can bring them a lot of joys and

happiness, because playing with pets is a good way to communicate with the

nature. Besides, pets can comfort old people who live alone. With the companion

of pets, they won’t feel lonely. Nevertheless, I’m not interested in keeping

pets at all. For one thing, keeping pets is bad for environmental protection,

since pets usually make a lot of noise and contaminate the roads. For another,

the virus carried by pets may cause fatal disease. What’s more, sometimes pets

may attack people when they are unhappy. Consequently, we had better not keep

too many pets, so as to ensure our health and security. Besides, those pet

lovers must take some effective measures to prevent their pets from hurting

people and polluting our environment.

We are always educated to be an honest person, especially to our parents. While the fact is that every kid will lie to their parents in their lives. For me, my parents are very strict, I am not allowed to go out at night, because the news always reports the bad incidents happen at night. But night activity attracts me a lot, and my friends like to hang out for fun at night, so I choose to lie to my parents and tell them I am doing my homework with my friends. Now as I grow up, I realize it is not right to tell lies, so I decide to be honest to my parents. Once they realize that I am not a little kid anymore, then I will have my right to do what I want.

adding the extra visiting without your permission.

interesting leisure activities for visitors is a common way to show welcome.

regard your private time as an inviolable treasure and hate to be harassed by

unplanned matters.

Im really sorry that I didnt check with you before making such

incomsiderate arrangement .All I can say is that it wont happen again.

Sincerely,

Friend plays important role in our lives. Everyone needs his or her own

friends. Some people make friends easily but some do not. And “friend” means

differently to people. Some people think friends should stay together all the

time, but some others think that share and support is the real meaning of

friend. From my point of view, friend is the person who will always be with you

no matter what happens. It’s the person who can share your happiness as well as

sorrows.

Life is long, the years.

How can we predict the future? But only clear conscience my heart! Life, because there is competition, people have power; Life, because of the struggle, the people to the pursuit of excellence.

Smoke in life, like a cloud, the wind. Transient. "Only the people and the backing car, there is no reverse time and road", since we came to today, and possession of todays social status and responsibility, only forward, forward, forward again! Dont retreat. Young people, more important is to see tomorrow, seize today, forge ahead in the quiet, perhaps before the sun mountain tomorrow, you created a miracle again!

Every child has pocket money, when they get the money from parents, most of them will buy what they want and spend the money quickly. Parents will give their children pocket money in the certain time, the children can use the money in a wise way. They can take out some money to buy what they need, like the food and clothes, there are still some money left, what should they do to deal with the rest of the money?

Sometimes I will use the saved money to support my emergent situation, so there is no need for them to worry about me.

每个孩子都有零花钱，当父母给钱他们的时候，大部分人会买他们想要的，钱很快就被用完了。父母会在特定的时间给他们的孩子零花钱，孩子可以用更加理智的方式使用钱。他们可以拿出一些钱来买他们需要的，比如食物和衣服，仍然会有一些钱剩下了，他们应该怎么处理剩下的钱呢?我建议孩子们把钱省下来，他们可以存起来，以防特殊的需要。我会把钱省下来，在暑假里去旅游，父母会同意我的计划，因为我出的钱，他们没有理由反对我。有时候我会使用存起来的钱来应对我的紧急情况，这样就不必让父母担心我。

The quality of human life has improved greatly over the past few centuries, but Earth is being harmed more and more by human activity. As we develop our technology, we demand more from our planet. Eventually, this will harm people as well.

Our planet gives us everything we need, but natural resources are not endless. Strip mining devastates whole regions, leaving bare and useless ground. Deforestation removes old growth trees that cant be replaced. Too much fishing may harm fish populations to the point where they cant recover. We are too careless in taking what we want without giving anything back.

There are more people than ever, living longer that ever. So is it any surprise that many areas suffer from too much development? Anyone living in or near a city has experienced "urban sprawl". There is a new shopping area on every corner and new houses, townhouses and apartments everywhere. Traffic gets worse and worse because planners cant keep up with growth. Keeping up with human demand is hard enough. Environmental concerns come in last.

With growth comes pollution. Companies and communities dump waste into water. Landfills are full of trash. Emissions from factories pollute the air. Barrels of industrial waste and worse, radioactive waste, have no safe place to go. If were not careful, we can harm our planet beyond repair.

People need to respect the Earth and try to preserve it. If we dont, what kind of future will we have?

When I was very small, I was so envious about the adults, because they could do whatever they wanted and did not have to depend on their parents. For me, I did not have money and my parents limited my pocket money, so I couldn’t spend the money to buy whatever I wanted. It seems to me that being an adult is my only wish. Some day, I learned from the movie that being an adult was not that as perfect as I thought.

In the movie, the man struggled to earn money to pay his bills, what’s more, he had to stay away from his family.

Loneliness was always around him. To be independent means we can live our own way and make our own decision. We have more freedom. But at the same time, it also means more annoyance. So why just we enjoy this moment.

在我很小的时候,我很羡慕成年人,因为他们可以做任何他们想做的,不必依赖他们的父母。对我来说,我没有钱,我的父母限制我的零花钱,所以我无法花钱去买所有我想要的。似乎成为一个成年人是我唯一的愿望。有一天,我从这部电影中了解到，作为一个成年人也没有我想象中的那么完美。在电影中,那个人努力挣钱来支付他的账单,更重要的是,他不得不远离他的家人。寂寞总是是围绕着他。独立意味着我们可以有自己的方式生活,做自己的决定。我们有的自由。但与此同时,这也意味着的烦恼。所以为什么不享受这一刻呢。

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.
