2 . Since I became a teenager, I have thought a lot about my own future job and set goal for it. It’s very necessary and important for me now to decide what I want to become.In the past, I used to want to be an engineer because I’m good at drawing and building stuff, but my thought has changed through time. I end up all of my choices as a manager who manages the whole system in the service hotel.I have planned that I will study hard in high school, then finish IGCSE and IB with a high score. After that, I will move to a good school in USA to learn about business and the economy in my country.

During my life in university, I properly will apply to work for some small stores and hotels to have the feeling of how things work in the real life. Firstly, the reason I like to be a hotel manager is I find it interesting to use techniques to persuade more people to stay at the hotel. Secondly, I see that the development in business is the fastest growing in sectors of industry besides the primary and the secondary, so I can make a lot of money. Thirdly, it’s the range of community; it has a very high range to meet different people with different nationalities.

Fourthly, I want to have more confidence and become a good leader with skill, for example, I still can’t control and persuade people to listen to me sometimes when I’m in charge of PE’s lesson. The last reason why I strongly chose to be a hotel manager is because of my pressure from my family. They are the second generation of successful 3 stars hotels’ managers. They like me to become what I’m going to do when I become a manager.

3 . In the 1960s and 1970s, the greatest fear was that the human race, and possibly all advanced life forms on the planet, could be wiped out by nuclear missiles. Today, however, environmental problems have taken over as the greatest risk to life on Earth. Scientists are thinking of ways to lower this risk, such as replacing coal and oil with forms of renewable energy. But they are also preparing for the worst: what can we do if the terrifying scenes in films such as The Day After Tomorrow happen in real life? What is our plan B for Earth?

One option is to explore other planets to see if we could live on them. The most likely choice is Mars, which is relatively close to Earth and has an environment less hostile than that of other planets. Mars has fascinated people since ancient times, and today our interest in Martian exploration is greater than ever before. Besides, more governments are making efforts to educate the public on the Red Planet.

There is no doubt that humankind is drawn towards Mars. However, sending people there will require all the skill, courage and intelligence. While the Moon can be reached within days, it would take months to reach Mars, travelling through dangerous solar radiation. And even if the first settlers do reach Mars safely, they may not be able to return to Earth — ever. Staying alive will be a daily challenge, but as proved by the Biosphere 2 experiment, not impossible. As early as the 1980s, scientists were building Biosphere 2 in the Arizona desert, consisting of a closed space in which people, animals and plants could live together. Although the two-year experiment was not a success, it did provide us with a better understanding of how humans might be able to live on another planet.       

For now, human settlement of Mars is still decades away. Until we are finally able to live on another planet, we need to take much better care of our own. Right now, it's the only one we have!
