CHECKOUT      OPERATORS

　　0   Supermarket checkout operators sit at electronic tills and fill in the prices of the

　　00  customer’s goods . This is now done by “scanning”, pass each such item over

　　34  a device that reads the bar-code on it and automatically registers it down in the

　　35  till . They may weigh some products , such as for fruit , on scales near the

　　36  till . When all the goods will have been scanned ,the till provides a total and the

　　37  operators take payment in the cash , by cheque or by credit or debit card , and

　　38  give a till receipt and any more change required . They provide bags , often

　　39  help to pack purchase , and change paper till rolls as being necessary

　　40  They also make it sure they have enough change , credit card forms ,and carrier

　　41  bags . Operators ring a bell or buzzer to summon for a supervisor to help

　　42  with problems , and put notes and cheques into bags for periodic collection .

　　43  They enter into their personal details in the till , so that their performance can be

　　44  analyzed later . The system offers supermarkets an efficient way of handling with a

　　45  large number of customers purchasing many products and helps to keep checkout queues to a minimum .

　　Answers： 34 DOWN 35 FOR 36 WILL 37 THE

　　38 MORE 39 BEING 40 IT 41 FOR

　　42 CORRECT 43 INTO 44 WITH 45 CORRECT

　　详细解释：00 句意是：把“每个”商品置于某一设备上，以读取条形码，such在此多余。

　　34 register是及物动词，不用再接上down。

　　35 这里出题者通过such as和as for来干扰考生，根据句子意思，我们可以知道for是多余的。

　　36 时间状语从句用一般现在时表将来。

　　37 用现金支付用"in cash"中间没有定冠词。又如in pencil / in ink 等。

　　38 Any more是“不再”的意思.句意为“任何”，要用any。

　　39 As后面常接形容词或过去分词，如as needed/as required.句中being多余。

　　40 Make sure是固定结构，中间没有it。

　　41 Summon是及物动词，直接跟上宾语即可。

　　42 这一行没有错误。

　　43 Enter在这里是“输入”的意思，不与into连用。

　　44 Handle是及物动词，不需要再接with ，注意与deal / do with区别开来。

　　45 这一行没有错误。
