下面的材料从四个方面对二胡作了介绍，请筛选信息，保留各方面的主要内容，压缩成一段文字，不超过60个字。
二胡是中国的一种很奇妙的乐器，是胡琴的一种，比京胡大，也叫南胡。二胡的构造很简单：由一根长约80厘米的细细的木制琴杆、内外两根琴弦、琴杆下端的蒙着蟒皮或蛇皮的琴筒构成，琴筒呈茶杯形，用木或竹制成，蟒皮或蛇皮是制作二胡的重要材料；用马尾做的琴弓演奏，这与小提琴同样用马尾做琴弓是一样的。二胡声音低沉圆润，听起来略带忧伤，常用来表达比较深沉的情感。二胡产生的历史悠久，又比较容易学习，因此是深受中华民族喜爱的乐器，是中国民间普及率比较高的乐器。
解析：首先利用公式，确定主干句。二胡是一种乐器，“乐器”就是“二胡”的属性。根据题干“从四个方面对二胡作了介绍”，可以提炼出“二胡”的另外三个特征：①二胡的构造。②演出的材料及效果。③深受中华民族喜爱。然后嵌入公式，组成连贯的语句表达出来。

You may have goals of losing weight, dreaming of pursuing a passion or interest, plans of achieving success in your career and relationships, but without positive motivation, all these remain goals, plans and dreams if you are not motivated to achieve them and make them into reality. Positive thoughts play a major role in your outlook in life and in giving you the motivation to reach for you dreams. If you are optimistic that you can do the task at hand, or you can reach your goals, you will be motivated to take those steps towards achieving it.
|
Whether it is nature’s beauty, or great relationships from friends and family, being able to find inspiration has a positive impact in getting yourself motivated to do what you want to achieve and live a better life, so strive to make friends and keep a happy relationship with your family.
|
One of the things that can contribute to lack of motivation is doing the same things every day and getting stuck into it without knowing where you are heading. Sometimes you have to explore other opportunities, learn new skills and explore other interests. Do not be afraid to take risks, explore new ways of achieving your goals and get out of your comfort zone at times to discover new things around you and take advantage of new opportunities in life.
|
A tired and stressed body most often leads to lack of motivation to do what you want to do. Have a regular exercise. This will not only make you become stronger physically but will also lift up your mood to tackle (处理)life’s challenges each day.
|
Most often, we feel mostly motivated if there is a need to do it. Finding the reason why you live your life each day will truly make everything easy and help you get motivated. Dedicating(致力于) your efforts to someone you love and treasure is also a good motivation that you can give yourself. No matter what challenges you have to face, for as long as you know that you are doing it for someone you love, you will find yourself motivated to do it.
