All we assume is that some early men invented certain sounds, in one way or another, to express thoughts and feelings, actions and things, so that they could talk with each other. 阅读理解Later they agreed upon certain signs, called letters, which could be put together to show those sounds, and which could be written down. Those sounds, whether spoken or written in letters, are called words.
The power of words, then, lies in their associations — the things they bring up to our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words bring back to us the happy and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases.
Great writers are those who not only have great thoughts but also express these thoughts in words which have powerful effects on our minds and feelings. This clever use of words is what we call literary style. Above all, the real poet is a master of words. He can express his meaning in words which sing like music, and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them correctly, or they will make our speech silly and common.1.

阅读下面的短文,然后按照要求写一篇150词左右的英语短文。
A gap year (休假学年), also known as year abroad or year off, is a year during which students take time off and do something other than schooling, such as travel or work. The gap year is most commonly taken before starting university. The practice of taking a gap year developed in the UK in the 1960s. During a gap year, a student might travel, take part in volunteer work overseas or undertake a working holiday abroad.
In 1978, the Prince of Wales John Blashford-Snell began a gap year voyage around the world. In the United Stares, the gap year idea was promoted by Cornelius H. Bull in 1980. In recent years, the gap year has grown very popular among students in the UK, Australia, New Zealand and Canada. A trend for gap years is to participate in international education programs that combine language study, homestays, community service, and independent study.
In 2010, gap year travel has increased among school, college and university leavers, as this is seen as an attractive choice for future career development.[写作内容]
1. 以约30词概括上文的主要内容。
2. 以约120词对“休假学年”现象进行议论, 内容包括：
(1) 休假学年的好处；
(2) 休假学年的弊端；
(3) 假如你有休假学年, 你打算做什么？请说明理由。 The passage introduces the concept of gap year and its history. It is becoming increasingly popular for students to take a year off to do other things instead of schooling.
The advantages of taking a gap year are obvious. For one thing, it provides relaxation after tiring schooling. For another thing, with a gap year spent in other places or countries, students can experience foreign culture, broadening their horizon.
As the saying goes, every coin has two sides, and taking a gap year is no exception. After a gap year, students may forget what they’ve learned and fail to carry on the following schooling efficiently. Besides, a year outside school requires parents’ extra financial support.
As far as I am concerned, if I had a gap year, I would choose to teach Chinese in a foreign country. By doing this, I not only could learn more about my native language, but also would be able to introduce our culture to the outside world.Thank you !
