上海takego無人店地址

A. TakeGo無人店用到哪些技術如何實現拿了就走的

Takego系統之所以能實現「拿了就走」主要應用了卷積神經網路、Deep learning深度學習、機器視覺、生物識別、生物支付等人工智慧領域前沿技術，這其中涉及兩個關鍵的技術，一個是生物識別技術，從take go的應用場景視頻中可以看到，顧客進入take go無人店需要手掌按在生物識別讀寫器上，這個識別器不是掌紋或者指紋識別器，應該是靜脈識別器，靜脈識別技術要比指紋識別精確很多，也更大程度地避免了被冒用的可能性，很好地確保了用戶資金的安全性。另外一個關鍵技術是基於深度學習(Deep learning)的卷積神經網路技術，該技術主要用於對整個無人零售店內物品的監測、識別與跟蹤。其中，對商品的識別是通過機器學習，然後對圖像進行識別，也就是說每次商店進貨新品類時，都需要對該商品進行機器學習，將該商品的一些特徵數據信息記錄到資料庫中，然後圖像識別系統依據特徵數據信息對該商品進行識別。當顧客走進take go無人零售門店並拿起商品時，不管商品的位置是在顧客手上、懷中、口袋還是背包內，系統都能監測與識別，顧客離開商店時會收到對應的賬單，並被系統自動扣款。Take Go還有人店對話系統，通過定向聲源原理和演算法，TakeGo零售店還可以向顧客進行語音產品，根據顧客之前的購買記錄判斷出其喜好、偏向，向其講類似商品。

反意疑問句淺析
反意疑問句原則上遵循「前否定後肯定，前肯定後否定」的十二字口訣；但隨著現代語言的發展，有時也不遵循這樣的規則，發生了變化，變得更加口語化，這就需要我們對具體問題作具體分析。
1. Mr Green went to Shenzhen on business last week, _____? (福州市2004中考題)
A. isn』t he B. doesn』t he C. didn』t he D. hasn』t he
解析：
反意疑問句的後半部分（附加疑問句）必須在人稱、數和時態上與前面的陳述部分保持一致；當前一部分的主語部分為名詞時，後一部分的主語用相應的人稱代詞形式。本題中前一部分的謂語動詞為一般過去時的行為動詞的肯定形式，後一部分的助動詞只能是didn』t。
答案：C
2. You often have bread for breakfast, ____ you? (海南省1997中考題)
A. don』t B. haven』t C. aren』t D. will
解析：
have不當「有」講時，用作行為動詞。
have當「有」講進行句型轉換時，可以添加助動詞，也可以不加助動詞，如：
He has few friends in the new school, does / has he? (長沙市2003中考題)
答案：A
3. Alice has to finish her work now, _____? (河南省1999中考題)
A. has she B. hasn』t she C. does she D. doesn』t she
解析：
have to雖與must同義，但它變反意疑問句時要像行為動詞一樣去變。
答案：D
4. The poor man needs our help, _____ he? (河北省1999中考題)
A. need B. needn』t C. does D. doesn』t
解析：
need既可作行為動詞，又可作情態動詞。本題中need用了第三人稱單數形式，顯然是行為動詞，變反意疑問句時，附加疑問句中只能選用適當的助動詞。
答案：D
5. — Let』s go and fly kites, _____?
— Wonderful! (甘肅省2001中考題)
A. will you B. shall we C. don』t you D. do you
解析：
祈使句變反意疑問句，前一部分為肯定形式時，後一部分用will you，would you, can you, can』t you及could you；而前一部分為否定形式時，後一部分只能用will you。以let』s開頭的祈使句，附加疑問句常用shall we。
答案：B
注意：
let』s與let us是有區別的，let us像一般的祈使句一樣，附加疑問句應為will you。
6. There is little milk in the bottle, ______? (廣東省2003中考題)
A. isn』t there B. is there C. isn』t it D. is it
解析:
陳述部分是there be結構，附加疑問句用be (not) + there的形式。含有little, few, hardly, never, seldom, nothing等否定意義詞的陳述句，是否定句。本題中出現了little，故附加疑問句中的謂語動詞應為肯定形式。
答案：B
注意：
某些帶有否定前綴或後綴的形容詞如unhappy, careless（粗心）等，只是詞語意義的否定，而不能構成整個句子的否定。
7. I don』t think he』ll come here on time, ____? (重慶市2000中考題)
A. won』t he B. will he C. does he D. is he
解析：
陳述部分中如果含有賓語從句，附加疑問句的謂語動詞應與陳述部分的主句的謂語動詞在人稱、數和時態上保持一致。但如果主句含有I suggest（猜測），I believe(相信), I think, I guess, I hear等時，附加疑問句的謂語動詞應與其賓語從句的謂語動詞在人稱、時態和數上保持一致。本題中的謂語動詞應和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. (甘肅省2004中考題)
A. No, he didn』t B. Yes, he did C. No, he did D. Yes, he didn』t
解析：
對反意疑問句的回答，不管問題的提法如何，若事實是肯定的，就用yes，事實是否定的，就用no。當反意疑問句的結構為 「前否定後肯定」時，回答中的yes譯為「不」，no譯為「是的」，這一點與漢語不同。本題中答案表達的意義應為「他去上學了」。
答案：B（不，他去了）。
當然，在實際學習中，反意疑問句還有其他要點，這就需要我們勤於觀察、歸納，不斷豐富、充實我們的知識。

E. TakeGo無人值守智能門店才算真正的智能門店嗎

因為它採用的是人工智慧技術，卷積神經網路，機器視覺，DeepLearning深度學習，生物識別，生物支付等，去這種店鋪購物，只需要掃手進門拿了就走，整個店鋪就像個機器人，有自己的大腦，有眼睛，有嘴巴的。Takego系統之所以能實現「拿了就走」主要應用了卷積神經網路、Deep learning深度學習、機器視覺、生物識別、生物支付等人工智慧領域前沿技術，這其中涉及兩個關鍵的技術，一個是生物識別技術，從take go的應用場景視頻中可以看到，顧客進入take go無人店需要手掌按在生物識別讀寫器上，這個識別器不是掌紋或者指紋識別器，應該是靜脈識別器，靜脈識別技術要比指紋識別精確很多，也更大程度地避免了被冒用的可能性，很好地確保了用戶資金的安全性。另外一個關鍵技術是基於深度學習(Deep learning)的卷積神經網路技術，該技術主要用於對整個無人零售店內物品的監測、識別與跟蹤。其中，對商品的識別是通過機器學習，然後對圖像進行識別，也就是說每次商店進貨新品類時，都需要對該商品進行機器學習，將該商品的一些特徵數據信息記錄到資料庫中，然後圖像識別系統依據特徵數據信息對該商品進行識別。當顧客走進take go無人零售門店並拿起商品時，不管商品的位置是在顧客手上、懷中、口袋還是背包內，系統都能監測與識別，顧客離開商店時會收到對應的賬單，並被系統自動扣款。Take Go還有人店對話系統，通過定向聲源原理和演算法，TakeGo零售店還可以向顧客進行語音產品講解，根據顧客之前的購買記錄判斷出其喜好、偏向，向其講解類似商品。

F. 求一首英文歌的歌名

《You are my everything》歌詞：

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

H. 阿里的無人超市和亞馬遜的區別知乎

亞馬遜推出的Amazon Go，除了顧客無需結賬，即買即走，免去了顧客排隊的苦惱外，Amazon Go跟普通的零售店幾乎沒有區別，其商品擺設與普通零售店亦基本一致，主要銷售即食早餐、午餐和晚餐，以及每天新鮮的小點心。此外還包括麵包、牛奶、手工乳酪和本地製作的巧克力等。

Amazon Go的購物流程較為簡單，消費者在進入Amazon Go進行購物時首先需要一個亞馬遜帳號，並在自己的智能手機上安裝亞馬遜的應用軟體，用戶打開手機並進入商店後，在入口處會對顧客進行人臉識別，確認用戶身份。當消費者在貨架前停留並選擇商品時，攝像頭會捕捉並記錄顧客拿起或放下的商品，同時，置於貨架上的攝像頭會通過手勢識別判斷顧客是否將貨物置於購物籃還是只是看看然後放回原處。

對於用戶購物信息的統計，則是通過貨架上的紅外感測器、壓力感應裝置(確認哪些商品被取走)及荷載感測器(用於記錄哪些商品被放回原處)，用戶所采購的商品數據會實時傳輸至 Amazon Go商店的信息中樞，不會有任何延遲，顧客付賬時直接離店就可，感測器會掃描並記錄下消費者購買的商品，同時自動在消費者的賬戶上結算出相應的金額。

Amazon Go最大的亮點是顧客拿走或者放回物品的同時，用戶手機里的系統(該系統與Amazon Go商店的信息中樞無延遲地同步進行更新)會自動更新清單，然後用戶直接離開商店即可。

從技術上講，Amazon Go主要運用了機器視覺、深度學習演算法和感測器融合技術，這三項技術幾乎都是當下最為熱門前沿的技術了，筆者認為，這些前沿技術的大規模實施肯定會造價不菲，相信這也是當前Amazon Go沒有大規模應用的原因之一(Amazon Go原定於今年7月落地的計劃因技術原因被延期)。

阿里淘咖啡

說到了亞馬遜，阿里巴巴恐怕也不得不提及了。作為阿里實驗室籌劃已久的「無人零售計劃」中的第一個應用場景，「淘咖啡」將在7月初的第二屆淘寶造物節上亮相，「淘咖啡」是一個佔地200平方的線下實體店樣板，集商品購物、餐飲於一體。

下面不妨來看看「淘咖啡」的購物過程是怎樣的。

消費者進入淘咖啡的整個購物過程大致分為三個步驟，首先是進店，用戶首次進店需打開「手機淘寶app」，掃碼獲得電子入場碼，同時簽署數據使用、隱私保護聲明、支付寶代扣協議等條款，顧客將手機放在認證閘機上方以通過驗證即可開始購物，之後全程無需再掏手機;

接著是選購，用戶可在店內拿起任何一件或者多件商品，或者在餐飲區點餐，這個過程與日常的購物並無二致;

最後是支付，支付的過程是通過一道結算門完成的，離店前，用戶必須經過這道結算門。結算門由兩道門組成，當第一道門感應到用戶的離店需求時，它便會自動開啟，用戶走出這道門後，系統會自動對顧客所買的貨物進行識別與結算，結算完成後，會有語音提示顧客此次購物所花金額，隨即第二道門便會自動打開，顧客離店。

阿里的這套無人零售技術主要涉及三大核心技術，即生物特徵自主感知和學習系統、結算意圖識別和交易系統及目標檢測與追蹤系統。

生物特徵自主感知和學習系統主要解決在開放空間里對消費者身份的識別問題，將顧客的生物特徵與淘寶ID進行綁定，以實現對顧客的身份確認。

對商品的識別是如何實現的?主要依賴結算意圖識別和交易系統來完成，如前文所言的結算門，它是由兩道門組成，對商品的識別過程就是在這兩道門之間完成的，阿里的這套系統究竟是通過RFID技術還是機器視覺識別來完成對商品識別的，目前還不能十分確定，筆者以為機器視覺識別的可能性更大一些。

目標檢測與追蹤系統則主要是追蹤消費者在店內的行為及運動軌跡，該功能主要依賴多路監控攝像頭。通過捕捉消費者的行為判斷其對特定商品的態度，或通過對諸多消費者在店內的運動軌跡、或在特定貨架前的停留時間來指導商家調整貨品的陳列方式等。

I. 中文翻譯成英文

翻譯如下，希望能幫到你
我不喜歡做個病貓，但卻又常常說自己不舒服，其實我一點也沒有不舒服。只有結婚前夕緊張，臨時抱佛腳或是巨大的壓力，才會真正令我不舒服。
可是今早，我還是覺得自己應該請一天的假，天啊，其實我覺得我應該請兩天。所以今早我做的第一件事，就是打電話請假。雖然我不是撒謊高手，但要騙過Penny,
一點都不難。總比要騙過老闆容易許多。
我大約地想過今天應該做一些讓自己高興的事，一些平常我不做的事。美甲護理，腳部護理，
美容等等的事。可是我還是斗不過自己的良心譴責。我知道，雖然我家和公司有點距離，但騙大家說我生病，過後又光明正大的出門，搞不好真的會在街尾碰到同事。
所以我只好獃在家，在這寒冷的一月季節里，開著無聊的早晨電視（雖然我剛剛開到了一個挺有用的，關於結婚的節目）。我邊看電視，邊吃著奶油酥（這或許是我最後一次吃肥膩的食物了，我很快就要為我的婚禮，進行地獄式減肥計劃）。我正在想，現在是否來得及，請一個按摩師回家，來給我減壓減壓。
我終於搞清楚了。裝病所帶來的良心譴責就是令自己不敢出門，白白浪費一天的時間。當然，
你越沒事做，你就越不想找事做。到了下午兩點時，我已經是又悶，又慢無目的和想睡覺。
我沒有直接跑去睡，反而喝了杯濃濃的咖啡，沖了個澡，換了一身干凈的衣服。

抓緊時間吧，沒什麼大不了的，去做就行了。
