【题目】Parents are the most important people in our life. They influence our lives in so many ways. They teach us almost everything about living, give us strength of character and make us who we are. It is because of them that we become able to do our duties. The things that we are able to do are actually their gifts to us. Right from taking care of us when we are young to guiding us whenever we need their advice, they are always there by our side.

All we can do for them is to give them love and happiness and try to make them feel proud of us. First of all, you need to follow all the good things they taught you when you were very young. It could be eating healthily or exercising in a regular way, or it could be helping anyone who needs help.

Not make complaints is also a good way. So don’t complain about what you don’t have. Learn to appreciate(感激) and love what your parents give you; you may not know the struggles they go through in order to give you that.

Thirdly, you also need to start making your own decision wisely and confidently. In other words, take control of your life by deciding what will be good or bad for you. Let them see that you are able to do all kinds of things without asking others for help.

More importantly, you should try to be a good person. Be polite and respectful to your family and friends. When they give you advice or suggestions, you’d better take their ideas into consideration. Try to work as hard as you can and be modest with what you have achieved. Anyway, seeing you grow into a good person will surely make your parents proud.

【题目】阅读下面短文,并根据短文内容在在文章后表格中的空格里填入一个最恰当的单词。每空一词。

How important is music? When they are asked this question, students and parents usually answer that music is nice, but not very important. It is often considered only as entertainment, but not the first choice for education. This opinion is shortsighted. In fact, music education is necessary and important for all students.

Music tells us who we are. Music reflects the creators’ thinking and values, as well as the social environment it came from. For example, just as Mozart music represents a lifestyle, rock music represents a lifestyle, too. The jazz influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical traditions.

Music provides a kind of ability to know the world in a different way. Science explains how the sun rises and sets. Music explores the emotive meanings. We need every possible way to discover and response to our world because no one way can get it all.

Music is a form of thought, as powerful as science. It is a way we human beings “talk” to each other. Through the language we expresses our feelings, our discoveries, our ideas, our imagination and our hopes so that they can be shared with others. When we do not let our children receive good music education, we take away from them the meanings that music expresses. Science does not tell us what it means to be human. Music does.

So music education is much more necessary than people generally realize.
