上海takego无人店地址

A. TakeGo无人店用到哪些技术如何实现拿了就走的

Takego系统之所以能实现“拿了就走”主要应用了卷积神经网络、Deep learning深度学习、机器视觉、生物识别、生物支付等人工智能领域前沿技术，这其中涉及两个关键的技术，一个是生物识别技术，从take go的应用场景视频中可以看到，顾客进入take go无人店需要手掌按在生物识别读写器上，这个识别器不是掌纹或者指纹识别器，应该是静脉识别器，静脉识别技术要比指纹识别精确很多，也更大程度地避免了被冒用的可能性，很好地确保了用户资金的安全性。另外一个关键技术是基于深度学习(Deep learning)的卷积神经网络技术，该技术主要用于对整个无人零售店内物品的监测、识别与跟踪。其中，对商品的识别是通过机器学习，然后对图像进行识别，也就是说每次商店进货新品类时，都需要对该商品进行机器学习，将该商品的一些特征数据信息记录到数据库中，然后图像识别系统依据特征数据信息对该商品进行识别。当顾客走进take go无人零售门店并拿起商品时，不管商品的位置是在顾客手上、怀中、口袋还是背包内，系统都能监测与识别，顾客离开商店时会收到对应的账单，并被系统自动扣款。Take Go还有人店对话系统，通过定向声源原理和算法，TakeGo零售店还可以向顾客进行语音产品，根据顾客之前的购买记录判断出其喜好、偏向，向其讲类似商品。

反意疑问句浅析
反意疑问句原则上遵循“前否定后肯定，前肯定后否定”的十二字口诀；但随着现代语言的发展，有时也不遵循这样的规则，发生了变化，变得更加口语化，这就需要我们对具体问题作具体分析。
1. Mr Green went to Shenzhen on business last week, _____? (福州市2004中考题)
A. isn’t he B. doesn’t he C. didn’t he D. hasn’t he
解析：
反意疑问句的后半部分（附加疑问句）必须在人称、数和时态上与前面的陈述部分保持一致；当前一部分的主语部分为名词时，后一部分的主语用相应的人称代词形式。本题中前一部分的谓语动词为一般过去时的行为动词的肯定形式，后一部分的助动词只能是didn’t。
答案：C
2. You often have bread for breakfast, ____ you? (海南省1997中考题)
A. don’t B. haven’t C. aren’t D. will
解析：
have不当“有”讲时，用作行为动词。
have当“有”讲进行句型转换时，可以添加助动词，也可以不加助动词，如：
He has few friends in the new school, does / has he? (长沙市2003中考题)
答案：A
3. Alice has to finish her work now, _____? (河南省1999中考题)
A. has she B. hasn’t she C. does she D. doesn’t she
解析：
have to虽与must同义，但它变反意疑问句时要像行为动词一样去变。
答案：D
4. The poor man needs our help, _____ he? (河北省1999中考题)
A. need B. needn’t C. does D. doesn’t
解析：
need既可作行为动词，又可作情态动词。本题中need用了第三人称单数形式，显然是行为动词，变反意疑问句时，附加疑问句中只能选用适当的助动词。
答案：D
5. — Let’s go and fly kites, _____?
— Wonderful! (甘肃省2001中考题)
A. will you B. shall we C. don’t you D. do you
解析：
祈使句变反意疑问句，前一部分为肯定形式时，后一部分用will you，would you, can you, can’t you及could you；而前一部分为否定形式时，后一部分只能用will you。以let’s开头的祈使句，附加疑问句常用shall we。
答案：B
注意：
let’s与let us是有区别的，let us像一般的祈使句一样，附加疑问句应为will you。
6. There is little milk in the bottle, ______? (广东省2003中考题)
A. isn’t there B. is there C. isn’t it D. is it
解析:
陈述部分是there be结构，附加疑问句用be (not) + there的形式。含有little, few, hardly, never, seldom, nothing等否定意义词的陈述句，是否定句。本题中出现了little，故附加疑问句中的谓语动词应为肯定形式。
答案：B
注意：
某些带有否定前缀或后缀的形容词如unhappy, careless（粗心）等，只是词语意义的否定，而不能构成整个句子的否定。
7. I don’t think he’ll come here on time, ____? (重庆市2000中考题)
A. won’t he B. will he C. does he D. is he
解析：
陈述部分中如果含有宾语从句，附加疑问句的谓语动词应与陈述部分的主句的谓语动词在人称、数和时态上保持一致。但如果主句含有I suggest（猜测），I believe(相信), I think, I guess, I hear等时，附加疑问句的谓语动词应与其宾语从句的谓语动词在人称、时态和数上保持一致。本题中的谓语动词应和will come保持一致。
答案：B
8. — He didn’t go to school this morning, did he?
— ___, though he was not feeling very well. (甘肃省2004中考题)
A. No, he didn’t B. Yes, he did C. No, he did D. Yes, he didn’t
解析：
对反意疑问句的回答，不管问题的提法如何，若事实是肯定的，就用yes，事实是否定的，就用no。当反意疑问句的结构为 “前否定后肯定”时，回答中的yes译为“不”，no译为“是的”，这一点与汉语不同。本题中答案表达的意义应为“他去上学了”。
答案：B（不，他去了）。
当然，在实际学习中，反意疑问句还有其他要点，这就需要我们勤于观察、归纳，不断丰富、充实我们的知识。

June came and the hottest month of the year began. A lot of travellers came to the city by the sea. All of the hotels were full except Mr Johnson’s. The prices of all the rooms were the lowest in the city but few people stayed there. The fire(火灾）broke out three times in a year and four travellers died in the accidents.

“It doesn’t matter. I think you have a lift in your hotel.”
“Of course, sir,” said the manager. “It’ll take you right there. By the way, may I keep your bag for you?”

E. TakeGo无人值守智能门店才算真正的智能门店吗

因为它采用的是人工智能技术，卷积神经网络，机器视觉，DeepLearning深度学习，生物识别，生物支付等，去这种店铺购物，只需要扫手进门拿了就走，整个店铺就像个机器人，有自己的大脑，有眼睛，有嘴巴的。Takego系统之所以能实现“拿了就走”主要应用了卷积神经网络、Deep learning深度学习、机器视觉、生物识别、生物支付等人工智能领域前沿技术，这其中涉及两个关键的技术，一个是生物识别技术，从take go的应用场景视频中可以看到，顾客进入take go无人店需要手掌按在生物识别读写器上，这个识别器不是掌纹或者指纹识别器，应该是静脉识别器，静脉识别技术要比指纹识别精确很多，也更大程度地避免了被冒用的可能性，很好地确保了用户资金的安全性。另外一个关键技术是基于深度学习(Deep learning)的卷积神经网络技术，该技术主要用于对整个无人零售店内物品的监测、识别与跟踪。其中，对商品的识别是通过机器学习，然后对图像进行识别，也就是说每次商店进货新品类时，都需要对该商品进行机器学习，将该商品的一些特征数据信息记录到数据库中，然后图像识别系统依据特征数据信息对该商品进行识别。当顾客走进take go无人零售门店并拿起商品时，不管商品的位置是在顾客手上、怀中、口袋还是背包内，系统都能监测与识别，顾客离开商店时会收到对应的账单，并被系统自动扣款。Take Go还有人店对话系统，通过定向声源原理和算法，TakeGo零售店还可以向顾客进行语音产品讲解，根据顾客之前的购买记录判断出其喜好、偏向，向其讲解类似商品。

F. 求一首英文歌的歌名

《You are my everything》歌词：

All my everthing

There's nothing that can harm you

In the lonely night

I'll come to you

And keep you safe and warm

It's so strong my love

When I kiss your lips

I feel the rolling thunder

To my fingertips

And all the while my head is in a spin

Deep within I'm in love

When I kiss your lips

I live up on the land

And see the sky above

I swim within her ocean

Sweet and warm

There's no storm my love

You're my everything

And nothing really matters

But the love you bring

You're my everything

To see you in the morning

With those big brown eyes

You're my everything

Forever and a day

I need you close to me

You're my everything

You never have to worry neve fear

For I am near

All my everything

I live up on the land and see the sky above

I swim within her ocean sweet and warm

There's no storm my love

You're my everything （王杰演唱的歌曲）

《You're my everything》是一首由Scarano-Donnez.Gomez作词、作曲，陈志远编曲，歌手王杰演唱的英文歌曲，收录在专辑《孤星》中，由飞碟唱片于1989年08月11日发行。歌曲翻唱自Santa Esmeralda的歌曲，原歌曲发表于1977年01月01日的《Don't Let Me Be Misunderstood》专辑。

王杰，原名王大为，华语男歌手、演员、音乐制作人。1962年10月20日生于香港，祖籍陕西西安。3岁父母移居香港定居。幼年在多部邵氏电影中扮演角色。从1987年12月出道以来，王杰发行专辑80多张。

H. 阿里的无人超市和亚马逊的区别知乎

亚马逊推出的Amazon Go，除了顾客无需结账，即买即走，免去了顾客排队的苦恼外，Amazon Go跟普通的零售店几乎没有区别，其商品摆设与普通零售店亦基本一致，主要销售即食早餐、午餐和晚餐，以及每天新鲜的小点心。此外还包括面包、牛奶、手工奶酪和本地制作的巧克力等。

Amazon Go的购物流程较为简单，消费者在进入Amazon Go进行购物时首先需要一个亚马逊帐号，并在自己的智能手机上安装亚马逊的应用软件，用户打开手机并进入商店后，在入口处会对顾客进行人脸识别，确认用户身份。当消费者在货架前停留并选择商品时，摄像头会捕捉并记录顾客拿起或放下的商品，同时，置于货架上的摄像头会通过手势识别判断顾客是否将货物置于购物篮还是只是看看然后放回原处。

对于用户购物信息的统计，则是通过货架上的红外传感器、压力感应装置(确认哪些商品被取走)及荷载传感器(用于记录哪些商品被放回原处)，用户所采购的商品数据会实时传输至 Amazon Go商店的信息中枢，不会有任何延迟，顾客付账时直接离店就可，传感器会扫描并记录下消费者购买的商品，同时自动在消费者的账户上结算出相应的金额。

Amazon Go最大的亮点是顾客拿走或者放回物品的同时，用户手机里的系统(该系统与Amazon Go商店的信息中枢无延迟地同步进行更新)会自动更新清单，然后用户直接离开商店即可。

从技术上讲，Amazon Go主要运用了机器视觉、深度学习算法和传感器融合技术，这三项技术几乎都是当下最为热门前沿的技术了，笔者认为，这些前沿技术的大规模实施肯定会造价不菲，相信这也是当前Amazon Go没有大规模应用的原因之一(Amazon Go原定于今年7月落地的计划因技术原因被延期)。

阿里淘咖啡

说到了亚马逊，阿里巴巴恐怕也不得不提及了。作为阿里实验室筹划已久的“无人零售计划”中的第一个应用场景，“淘咖啡”将在7月初的第二届淘宝造物节上亮相，“淘咖啡”是一个占地200平方的线下实体店样板，集商品购物、餐饮于一体。

下面不妨来看看“淘咖啡”的购物过程是怎样的。

消费者进入淘咖啡的整个购物过程大致分为三个步骤，首先是进店，用户首次进店需打开“手机淘宝app”，扫码获得电子入场码，同时签署数据使用、隐私保护声明、支付宝代扣协议等条款，顾客将手机放在认证闸机上方以通过验证即可开始购物，之后全程无需再掏手机;

接着是选购，用户可在店内拿起任何一件或者多件商品，或者在餐饮区点餐，这个过程与日常的购物并无二致;

最后是支付，支付的过程是通过一道结算门完成的，离店前，用户必须经过这道结算门。结算门由两道门组成，当第一道门感应到用户的离店需求时，它便会自动开启，用户走出这道门后，系统会自动对顾客所买的货物进行识别与结算，结算完成后，会有语音提示顾客此次购物所花金额，随即第二道门便会自动打开，顾客离店。

阿里的这套无人零售技术主要涉及三大核心技术，即生物特征自主感知和学习系统、结算意图识别和交易系统及目标检测与追踪系统。

生物特征自主感知和学习系统主要解决在开放空间里对消费者身份的识别问题，将顾客的生物特征与淘宝ID进行绑定，以实现对顾客的身份确认。

对商品的识别是如何实现的?主要依赖结算意图识别和交易系统来完成，如前文所言的结算门，它是由两道门组成，对商品的识别过程就是在这两道门之间完成的，阿里的这套系统究竟是通过RFID技术还是机器视觉识别来完成对商品识别的，目前还不能十分确定，笔者以为机器视觉识别的可能性更大一些。

目标检测与追踪系统则主要是追踪消费者在店内的行为及运动轨迹，该功能主要依赖多路监控摄像头。通过捕捉消费者的行为判断其对特定商品的态度，或通过对诸多消费者在店内的运动轨迹、或在特定货架前的停留时间来指导商家调整货品的陈列方式等。

I. 中文翻译成英文

翻译如下，希望能帮到你
我不喜欢做个病猫，但却又常常说自己不舒服，其实我一点也没有不舒服。只有结婚前夕紧张，临时抱佛脚或是巨大的压力，才会真正令我不舒服。
可是今早，我还是觉得自己应该请一天的假，天啊，其实我觉得我应该请两天。所以今早我做的第一件事，就是打电话请假。虽然我不是撒谎高手，但要骗过Penny,
一点都不难。总比要骗过老板容易许多。
我大约地想过今天应该做一些让自己高兴的事，一些平常我不做的事。美甲护理，脚部护理，
美容等等的事。可是我还是斗不过自己的良心谴责。我知道，虽然我家和公司有点距离，但骗大家说我生病，过后又光明正大的出门，搞不好真的会在街尾碰到同事。
所以我只好呆在家，在这寒冷的一月季节里，开着无聊的早晨电视（虽然我刚刚开到了一个挺有用的，关于结婚的节目）。我边看电视，边吃着奶油酥（这或许是我最后一次吃肥腻的食物了，我很快就要为我的婚礼，进行地狱式减肥计划）。我正在想，现在是否来得及，请一个按摩师回家，来给我减压减压。
我终于搞清楚了。装病所带来的良心谴责就是令自己不敢出门，白白浪费一天的时间。当然，
你越没事做，你就越不想找事做。到了下午两点时，我已经是又闷，又慢无目的和想睡觉。
我没有直接跑去睡，反而喝了杯浓浓的咖啡，冲了个澡，换了一身干净的衣服。
