could you help me with this composition? Thanks so much! Takeaway Food Nowadays, takeaway food enjoys great popularity in China and it is the best reflection of fast-paced modern society. We're just wondering the reason why takeaway food is so popular in China. Perhaps we could find out two reasons about it. Firstly, we are so oppcupied with heavy workload and house chores that we have less time to do anything else like cooking food. The present society is filled with competition and high pressure that we use much time to strengthen our working and learning skills. Then we find that making food by ourselves really wastes our time and ineffectively. Moreover, it's convenient to get food by sending rather than going out for a meal. All we need is just staying at home and waiting the knocks from a takeaway member. It's much more time-saving and labor-saving, isn't it? Secondly, we could not make so many various and special food by ourselves due to the limited food materials and machines. For instance, if you desire to eat spicy crawfish, you need to buy the fresh crawfish and handle them with condiments which cost much time and need many steps. It is so complicated and hard to make it tasty. However, from the aspect of nutrition, we often have bad feelings about takeaway food. We find that they often use stale food materials and inferior oil which makes us feel awful and could cause diseases. So it is prudent and proper to give it a shot not often.

A presentation Hello everyone! I'm Esther. It's my turn to show my group's achievement. My group has the numbers of name++name+name+name. We were allocated to introduce one of Chinese Cuisines-Cantonese Cuisine. But it has a large number of dishes that could not be completely introduced during one class. So we pick up the most typical three to introduce. Okay, let's have a look and check it. The first one is Kylin Weever.This dish is named for its shape like a unicorn.(unicorn is an animal in ancient mythology, shaped like a deer with horns and a body with scales as a symbol of auspiciousness) The main ingredients of the unicorn bass are ham, mushroom, fat pork, bass. The color is even orderly, pleasing to the eye and the meat is fresh and tender. It contains protein, vitamin A, B vitamins, calcium and other nutrients, with the effect of kidney, spleen and stomach, phlegm cough.

My Future Career As for me, I plan to be a Chinese teacher who teaches Chinese to foreigners in the near future. Since my major is teaching Chinese as a second language and I have studied it for nearly four years, I have the teaching abilities to be well qualified for this position. Moreover, it's a good chance to spread Chinese culture and customs to the people around the world in order to make them know well about our current situations and remove those misunderstandings. Fortunately, most governments and universities are willing to open Chinese courses and seek the chance to cooperate with Hanban (the Office of Chinese Language Council International) for studying Chinese. That means they need a large number of Chinese teachers and their citizens are deeply interested in Chinese. So there are huge vacant job positions that I can apply for. It is a promising and emerging field that has infinite chances. I have great confidence in making some achievements in this field and I will regard it as my lifetime career no matter how much troubles or difficulties I will meet. Now, I assume that I should read more relevant books and enlarge my scope of knowledge in order to teach well in the class.
