Which is Better, School Education or Family Education

Which is Better, School Education or Family Education

10英语A班孙马德2010040101012 Recently the news that a 12-year-old boy without any normal school education has been accepted by a key university in China aroused people’s interest. As a result, some people argue that school education exerts too much pressure on our children and they prefer to let their children educated at home, while others hold the opinion that normal school education is of the essence for children. From my own perspective, school education is much better than family education.

To begin with, although children accepting education at home have less pressure than those at school, meanwhile they lose an environment that is much more conducive to their growth and development. As the saying goes, “Adversity makes a man wise.” School is full of competitions. Children who accept school education will find that only under continuous improvements can they win the competitions. So they will spare no effort to absorb the teachers’ knowledge and learn from other classmates. The mutual studies and competitions are just what the family education lacks.

In addition, how can those parents guarantee that if their children educated at home to avert the pressure of studying at school, they can make their child admitted by a first-class university in the future? There is no denying that some children can be well self-educated at home and they can enter a university without any school education. However, you also have to acknowledge that there are real geniuses existing in the world and they are just in the minority. If parents blindly let their children accept family education, they might be ruining their children’s bright future.

Last but not least, children can gain a lighthearted childhood from school education while family education cannot. At school, children can make friends with different children and experience different things. They can play games with others to enjoy themselves and do all kinds of sports to strengthen their bodies. But at home, what children meet everyday are a handful of family members and what they do everyday is to face the blank walls and then study alone. There is no doubt that childhood is a precious period of our life which we should carefully cherish.

To draw a conclusion, school education outweighs family education, because school can provide a more prominent condition and environment for children to grow healthily and happily. Therefore, parents should let their children educated at school rather than at home.

before用法归纳

before用法知多少？ 在高考中，状语从句是每年高考单项填空部分必考的题目之一，考查的重点是考生容易混淆并且近似的连词在逻辑行文和语篇结构中的使用。before作连词的用法一直是高考的重点，也是学生感觉掌握起来比较头疼的地方。下面选取近几年各省市的高考试题进行归纳分析，使考生通过典型实例，把握高考对before所引导的句型的命题规律，帮助同学们更好地解答此类题目。 1. before作为连词时的基本意义是“在……之前”，用于表示时间或顺序。 You can’t borrow books from the school library ______ you get your student card. (2009上海，32) A. before B. if C. while D. as 【解析】选A。考查连词，该句的意思是：在你得到你的学生卡之前你不能从学校图书馆借书。before表示先后顺序。 2. 表示“过了多久才……”，说明主句的持续时间比较长而从句的动作缓缓来迟。 (1) The American Civil War lasted four years _______ the North won in the end. (2005广东，30) A. after B. before C. when D. then 【解析】选B。本题考查连词before表示“在多久之后才……”的用法，根据本句含义“美国南北战争持续了四年，北方才最终取得胜利”，可知本题应选B。 (2) Several weeks had gone by I realized the painting was missing. (2004宁夏，39) A. as B. before C. since D. when 【解析】选B。before表示“过多久才……”。句意：几个星期已经过去了，我才意识到油画丢了。内含的意思是油画丢了好几个星期了，我才意识到。 3. 表示从句动作还没来得及发生或完成，主句动作就已经发生或完成了，意为“尚未……就”，“没来得及……就”，常用于before sb. can/ could…。 —Why didn’t you tell him about the meeting?

最新定语从句中的that和which的区别

定语从句中的that和which的区别： that和which在从句里都可以做宾语和主语，做宾语时可以省略。在定语从句中,有种说法叫"关宾省",意思是关系代词在限制性定语从句中作宾语可以省略,不管是that，which，还是whom。但是which能引导非限制性定语从句，that则不行。 只能用that的几种情况： 1. 当先行词为all, much, little, none及由any, every, some, no所构成的复合不定代词时。We should do all that is useful to the people. Please tell me anything that you know about the matter. 2. 当先行词被any, few, little, no, all, much, some等词修饰时。 You can take any seat that is free. There is little work that is fit for you. 3. 当先行词为序数词或被序数词所修饰时。 When people talk about the cities of China, the first that comes to my mind is Beijing. This is the fourth film that has been shown in our school this term. 4. 当先行词为形容词最高级或被形容词最高级修饰时。 The best that I could do was to apologize. This is the most interesting story book that I have ever read. 5. 当先行词被the very, the only, the last, the just, the same等修饰时。 This is the very book that I’m looking for. The only thing that we could do was to wait. 注意：先行词被the same修饰时，关系代词也可用as。 I need the same book that / as you have. 6. 当先行词既包含人又包含物时。 They are talking of the heroines and their deeds that interest them. 7. 当先行词是疑问代词who，which，what或主句以这些词开头时。 Who that has ever worked together with him doesn’t admire him? Which is the star that is nearer to the earth？ 8. 当先行词为主句表语或关系代词为从句表语时。 That’s a good book that will help you a lot. Our school is no longer the place that it used to be. 9. 先行词为time时，当time表示次数，引导词用that, 可省略。当表示时间，可用that 或when引导，都可省略。 I do remember the first time(that) I had ever heard the sweetest voice in the world. I did't remember the exact time （when/that）I arrived in Shanghai last month. 只能使用which的情况: 1. 在“介词＋关系代词”结构中，关系代词必须用which。 The house in which we live is very large. This is the reference book（参考书）of which the teacher is speaking. 注意：如果介词不放在修饰事物的限定性定语从句的句首，which就可换为that。 This is the question which/that we’ve had so much discussion about. =This is the question about which we’ve had so much discussion. 2. 先行词为“those＋表事物的复数名词”时，关系代词通常只用which而不用that。 You should grasp well those skills which may be used in the future work.

Stand up, please. 请起立。Don’t worry. 别担心。 can的用法：can是情态动词，表示“能，会，可以，被允许等”，其后接动词原形，否定形式为cannot，可缩写为can’t. She can speak Japanese. 她会讲日语。I can’t remember his name. 我不记得他的名字了。Can you spell your name? 你会拼写你的名字吗？ 5、现在进行时态：概念：表示现在（说话瞬间）正在进行或发生的动作，也可以表示目前一段时间内或现阶段正在进行的活动。 结构：由be动词(am, is, are) + 动词ing构成，其中be动词要与主语保持性数一致。 Mary is flying a kite in the park. 玛丽正在公园里放风筝。 --What are you doing now?你现在在干什么？ --I’m reading English. 我正在读英语。 Are they drawing the pictures now?他们正在画画吗？ 动词现在分词是动词原形变化而来的，规则变化如下： 1) 直接在动词后加ing play—playing, do—doing, talk—talking, sing--singing 2)以不发音的字母e结尾的动词，先去e，再加ing

A. when B. until C. that D. before （3）It ________ long before we _______ the result of the experiment. A. will not be...will know B. is...will know C. will not be...know D. is...know (4) Scientists say it may be five or six years_________ it is possible to test this medicine on human patients. A. since B. after C. before D. when 解析：答案为BDCC。考题 （1）(2)before 用于肯定的“It + will be + 时间段+ before...”句型中，表示“要过多久…才…”。 （3）before在本题中用于否定句,意为“过不了多久就会……”, 状语从句要用一般现在时代替一般将来时，可知C项为正确答案,句意是:要不了多久我们就会知道试验的结果了。 （4）宾语从句中含有句型“It + may be + 时间段+ before...”，表示“也许要过多久才……”，故选择答案C。 二、用于句型“it was +时间段+ before …” 表示“过了（多长时间）才……”。其否定形式“ it was not +时间段+ before …” 意为“不久就……”, “没过（多长时间）就……”。 It was some time ___________we realized the truth. A. when B. until C. since D. before 解析：答案为D。before用于句型“it was +时间段+ before …” 表示“过了（多长时间）才……”。该题题意是“过了一段时间我们才意识到事情的真相”。故正确答案为C项。 表示“在……之后……才”。副词“才”在汉语中强调某事发生得晚或慢。如果在含有before从句的复合句中，强调从句动作发生得晚或慢时，就可以应用这种译法。 The American Civil War lasted four years _______ the North won in the end. A. after B. before C. when D. then 解析：答案为B。本题考查连词before表示“在……之后才……”之的用法，根据本句含义“美国南北战争持续了四年，北方才最终取得胜利”，可知本题应选B。 三、表示“……还没来得及……就……”。目的在于强调从句动作发生之前，主句动作已发生。 —Why didn't you tell him about the meeting? — He rushed out of the room _________ I could say a word. A. before B. until C. when D. after 解析：答案为A。本题考查连词before表示“……还没来得及……就……”的用法。句意是“我还没来得及说一句话，他就冲出了房间”。 四、表示“在……之前就……”。这时主句与before从句中的两个动作按时间先后依次发生。 It was evening______ we reached the little town of Winchester. A. that B. until C. since D. before 解析：答案为D。本题考查连词before表示“在……之前就……”的用法。句意是“我们到达小镇Winchester 之前就已经是傍晚时分了”。 五、表示“趁……”，“等到……”，或“没等……就…… ”等。
