Structure analysis and writing
Some bookworms in my dormitory often spend hours reading their “Bible”, Practical English Grammar, and do a lot of exercises in that book, but I don’t care about it at all. My assumption is since I have never learned Chinese grammar, what’s the sense of learning English grammar? In fact, English grammar has alwaysbeen a big headache to me.
English grammar is very complicated because, unlike Chinese, there are many verb tenses. Even stranger than verb tenses, English grammar also contains something very confusing. For example,
I do not remember how many times my middle school teacher tried to “impose” the differences between used to and be used to on us. Sometimes he would go on with the explanation for 20 minutes or so. He even summarized the differences by listing three or four points for us to memorize. However, they could never stay in my mind. I do not remember how many times I got it wrong with the sentences containing used to or be used to on my exams. I was really confused with these two phrases, and I can never get them right.
In brief, I am allergic to learning English grammar. Curiously, I just wonder if the native speakers of English have a microcomputer in their brain to help them utter the two phrases promptly with just a click of their brain mouse
Translation

人们普遍认为英语是一种世界语言，很多不以英语为第一语言的国家经常使用英语。与其他语言一样，英语也变化很大。英语这种语言的历史可分为三个阶段：古英语、中古英语和现代英语。公元5世纪，三个日耳曼部落入侵英国，他们对英语语言的形成起了很大的作用，英语由此起源。中世纪和现代社会初期，英语的影响遍及不列颠群岛。自17世纪初伊始，全世界都开始感受到英语的影响。欧洲的探险和殖民历时百年，让英语发生了巨变。如今，美国电影、电视、音乐、贸易和技术（包括互联网在内）风靡一时，美国英语的影响尤为显著。

Chinese calligraphy, a distinctive art form, is proclaimed to be one of the unique art treasures in the world. Its formation and development is closely related to the emergence and evolution of Chinese characters, which, in the long course of history, have not only served as a vehicle for exchanging ideas and transmittingculture but also evolved into a unique art form. Calligraphic works is a faithful representation of calligraphers’ personal feelings, knowledge, self-cultivation, personality, and thus there exists a phrase that “seeing the calligrapher’s handwriting is like seeing the person”. As one of the treasures of Chinese culture, Chinese calligraphyshines splendidly in the world’s art treasure house.

(“你把那个叫帽子吗？”我对妻子说)，可以判断作者不喜欢那顶帽子，所以a. didn’t like the hat his wife had chosen 是正确答案。其他3个选择都与事实不符。 2. a 根据课文第9-10行‘You needn’t have said that, ’ my wife answered. ‘I needn’t remind you of that terrible tie you bought yesterday’, 可以判断只有a. his wife reminded him that he had bought a terrible tie 与课文的实际情况相符，是作者为对他妻子粗鲁讲话而后悔的原因，其他3个选择都与事实不符，也不合乎逻辑。 3. c a. mustn't (不应该)； b. wont(不想要)； c. needn't(不必)； d. don't need(不需要)4个选择中只有c. needn't 与后面一句It isn't necessary(没必要)的含义相同，所以选c. 4. d a. still 和d. yet 都有“还，仍然”的含义，但yet只能用于否定和疑问句中，表示“还没……”，still常用于肯定句中。前面一句是肯定句，用了still,本句是完成时态的否定句，因此只能选
