In the bag he found a piece of
题目没写错吗？A-D都不对啊？我猜原题是“In the bag he found a piece of paper on which some special words were written”之类的吧，答案是B，是由“write some special words on a piece of paper”转换而来的……因为不能把句子里的“on”去掉，所以A是错的……
clutching a large doughnut in a bag, that he caught a few words of what ...
这句话出自 哈利波特。
这句是个强调句式，it is/was + 被强调部分 + that 从句，被强调成分为状语。
其中，分词clutching这句是分词做状语表当时的状态 ，拿着一个大大的装在袋子里的甜甜圈。
在他回来的路上经过他们身边，他手里拿着一个大大的装在袋子里的甜甜圈，隐约听到他们说的几句话。

能翻译一下吗？不要机翻的,驴头不对马嘴........
In the US, people prefer waiting for a table to sitting with people they don't know. This means a hostess may not seat a small group until a small table is available, even if a large one is. If you are sitting at a table with people you don't know, it is impolite to light up a cigarette without asking if it will disturb them.在美国，人们更喜欢和陌生人拼桌吃饭。
这就意味着——除非有小桌子可用，否则请客的人是没办法让一小群同伴入座的，甚至有时一大群人也不行。
如果你坐的这桌有你不认识的人，那么在请求许可之前就吸烟是非常不礼貌的。
At American restaurants and coffee shops you are usually served tap water before you order. You may find the bread and butter is free, and if you order coffee, you may get a free refill.在美国的餐厅和咖啡厅，你通常会在点餐前得到一杯白开水的服务。
你可能会发现黄油面包是免费的，如果你点了咖啡，可能也会得到免费续杯服务。
Most cities and towns have no rules about opening and closing time for stores or restaurants, though they usually do make rules for bars. Especially in large cities, stores may be open 24 hours a day.大多数城镇没有对商店、餐厅的营业时间进行规定，然而酒吧却有相关的限制。
特别是在大城市里，商店可能是24小时营业的。
Serving in restaurants is often large; too large for many people. If you can't finish your meal but would like to enjoy the food later, ask your waitress or waiter for a “doggie bag”. It may have a picture of a dog on it, but everybody knows you're taking the food for yourself.餐厅里的食物分量通常很大，对很多人来说实在是很大。
如果你没有吃完你的餐点，但又想稍后继续享用，可以让服务员拿一个“打包盒”。
这个盒子上一般会有一个狗狗的图案印在上面，但是每个人都知道这里面的食物是你自己吃的。
Supper and dinner are both words for the evening meal. Some people have “Sunday dinner”. This is an especially big noon meal.supper和dinner两个词都是指晚饭。
有些人会吃sunday dinner，这个词的意思是特别丰盛的午饭。
Tips are not usually added to the check. They are not included in the price of the meal, either. A tip of about 15% is expected and you should leave it on the table when you leave. In some restaurants, a check is brought on a plate and you put your money there. Then the waiter or waitress brings you your change.小费和餐厅消费账单通常是分开的。
这些小费通常不包括在餐点的价格内。
一般来说小费大约是你消费数额的15%，并且你应该在你离开餐厅的时候把小费留在桌子上。
在有些餐厅里，会有一个装了账单的盘子递给你，你应该把小费放在盘子里，然后服务员就会把要找的零钱拿给你。

don't let the cat out of the bag
、“to let the cat out of the bag”，它的意思是“揭露一个秘密”，尤其是很重要、关键的那种。
关于这个词组的记载可以追溯到1760年，但据说此前一两百年就有这种说法了。
早在超市（或杂货店）出现之前，人们通常在当地的市场买菜。
农民和商人们在那里叫卖蔬菜水果、鸡蛋面包之类，此外还会出售肉类和家禽，通常都是些活的动物。
在一些特殊的场合（如节日盛宴），乳猪是采购单上一样很抢手的食物。
由于乳猪会乱动，当顾客挑选好并结账后，商人为了运送方便就把猪塞进一个帆布口袋（poke）里递给顾客。
然而，市场上的许多交易并不光明磊落，奸商有时会利用顾客一时走神，把一只流浪猫冒充乳猪放进袋子里。
直到顾客回家，“把猫从袋子里拿出来”（let the cat out of the bag），才发现这个骗局。
所以这个词组意味着是一个意外的，但通常令人讨厌的发现。
据说这也是谚语“不要买装在袋子里的猪”（don't buy a pig in a poke）的由来，也就是“不要不看现货就买东西”的意思。
而the World Wide Words website的经营者Michael Quinion对这个故事表示怀疑，他指出猫在袋子里会变得极度狂躁，因此很难把它误当成一头小猪。
也许这个词组是来自于某个人的经历，由于某种原因有一只猫在他袋子里，而戏剧性的效果则使这个故事广为流传。
2、：“A cat has nine lives.” （一猫有九命），这是一句英国的谚语。
据英国民间传说，猫的生命力很强，很不容易被弄死。
有人把猫从高处扔下，它能稳稳当当地落地；有时甚至把一只猫打得一动不动了，过会儿它又会复活过来。
这些传乎并非迷信，因为据《参考消息》报道，1979年南非的一个岛上发生了猫患，后来他们给其中的一百多只猫注射了一种致命的细菌，结果这一百多只猫不仅没有把细菌传染给其他的猫，而且它们本身也安然无恙。
现在，人们用“A cat has nine lives.”这个成语比喻某人有旺盛的生命力。
3、Kill two birds with one stone.（一石二鸟）比喻做一件事情就 可有两种成效 Let the Cat Out of the Bag This phrase meaning to disclose a secret is from an old scam of selling someone a suckling pig at market and then surreptitiously substituting a cat for the pig. If one lets the cat out of the bag, then the secret is revealed and the fraud discovered. The scam dates to at least 1530, but the phrase doesn't make its appearance until 1760. See also: Pig in a Poke. The phrase is most assuredly not a reference to the bag that held a cat 'o nine tails onboard ship. The phrase is not nautical in origin as some maintain.

mixly如何导入dfrobot产品库模块
1. 关键词的提取，取一篇网页的源文件（例如通过浏览器的“查看源文件”功能），我们可以看到其中的情况纷乱繁杂。
从认识和实践来看，所含的关键词即为这种特 征最好的代表。
于是，作为预处理阶段的一个基本任务，就是要提取出网页源文件的内容部分所含的关键词。
对于中文来说，就是要根据一个词典Σ，用一个所谓 “切词软件”，从网页文字中切出Σ所含的词语来。
在那之后，一篇网页主要就由一组词来近似代表了，p = {t1, t2， …， tn}。
一般来讲，我们可能得到很多词，同一个词可能在一篇网页中多次出现。
从效果（effectiveness）和效率（efficiency）考虑， 不应该让所有的词都出现在网页的表示中，要去掉诸如“的”，“在”等没有内容指示意义的词，称为“停用词”（stop word）。
这样，对一篇网页来说，有效的词语数量大约在200个左右。
2. 重复或转载网页的消除，与生俱来的数字化和网络化给网页的复制以及转载和修改再发表带来了便利，因此我们看到Web上的信息存在大量的重复现象。
这种现象 对于广大的网民来说是有正面意义的，因为有了更多的信息访问机会。
但对于搜索引擎来说，则主要是fu/mian的；它不仅在搜集网页时要消耗机器时间和网 络带宽资源，而且如果在查询结果出现，无意义地消耗了计算机显示屏资源，也会引来用户的抱怨，“这么多重复的，给我一个就够了”。
因此，消除内容重复或主 题内容重复的网页是搜索引擎抓取网页阶段的一个重要任务。
3、链接分析，大量的HTML标记既给网页的预处理造成了一些麻烦，也带来了一些新的机遇。
从信息检索的角度讲，如果系统面对的仅仅是内容的文字，我们能 依据的就是“共有词汇假设”（shared bag of words），即内容所包含的关键词集合，最多加上词频（term frequency 或tf、TF）和词在文档集合出现的文档频率（document frequency 或df、DF）之类的统计量。
机器学习句子相似度计算,最后怎么根据相似度高低排序返回原来的句...
先说一个还是从词的角度出发考虑的，最后的效果非常好，就是怎么样从词的向量得到句子的向量，首先选出一个词库，比如说10万个词，然后用w2v跑出所有词的向量，然后对于每一个句子，构造一个10万维的向量，向量的每一维是该维对应的词和该句子中每一个词的相似度的最大值。
这种方法实际上是bag of words的一个扩展，比如说对于 我喜欢用苹果手机 这么一句话，对应的向量，会在三星，诺基亚，小米，电脑等词上也会有比较高的得分。
这种做法对于bag of words的稀疏性问题效果非常好。
还做过一个直接训练句子的相似度的一个query2vec模型，效果也不错，就不细说了。
