Way of Inducing
At the cleaner's, I noticed the sign "In by 10 a.m., out by 5 p.m.”So I told the owner that I wanted to pick my clothing up at five. "It won't be ready," he said.
“But your sign says, 'In by 10 a.m., out by 5 p.m. ', ” I reminded him.
招客有方
在洗衣店，我看到招牌上写着：“上午10点进，下午5点出。”因此我就告诉店主我想在下午5点取衣服。“下午5点还不能取，”他说。
“但是你的牌子上写着：‘上午10点进，下午5点出’，”我提醒他说。
“哦，”他回答说：“那指的是我。”

一、短文选词填空
1．B 2．A 3．E 4．F 5．C 6．G
【解析】
本文是一篇说明文。主要讲述了日本人泡温泉和中国习俗的不同。并呼吁大家，如果到日本，一定不要错过这日式温泉。
1．句意：在冬天，我们喜欢去泡热温泉。根据“we like to take a hot spring bath”可知，在寒冷的冬天我们喜欢做的事情是泡温泉。故选B。
2．句意：他们把它当作他们日常生活的重要一部分。固定短语，daily life“日常生活”。故选A。
3．句意：日本人在进入澡堂之前，他们经常坐在一个小凳子上，用毛巾和肥皂清洗他们的身体。根据“wash…with towels and soap”可知，他们是在用毛巾和香皂清洗身体。body“身体”，是名词的单数形式。bodies“身体”，是名词的复数形式。根据“their”可知，这里需用复数形式。故选E。
4．句意：并且他们经常在公共浴池里给彼此搓后背。分析句子成分可知，这里不缺成分，可以填副词。often“经常”，是频率副词。故选F。
5．句意：在中国，当我们泡温泉的时候我们通常会穿浴袍。根据“But in Japan, people don’t wear bathing suits”可知，前后句转折，说明中国人会穿浴袍而日本人不穿。bathing suits“浴袍”。故选C。
6．句意：但是在日本，人们在浴池里不穿浴袍。分析句子成分可知，横线处缺介词，与后边的名词共同构成介词短语，表地点。根据第二段第二句“And they…wash each others backs in the public bath”可知，这里用介词in。故选G。
二、用所给单词的正确形式填空
7．What happens when water ________ (freeze)
8．When speaking of Korea, people always ________it to some pop stars. (connection)
9．I can’t put up with(忍受) the ________ weather in North China. (freeze)
10．Can you tell me the ________ between the two words (different)
11．Nowadays, Chinese people are worried about the ________ of food in their life. (safe)
12．I can’t understand the ________ of this sentence. (mean)
13．May I use your pen There is something wrong with ________.(I)
7．freezes【详解】
句意：水结冰时会发生什么？本句时态是一般现在时，主语是不可数名词，动词用三单。故填freezes。
8．connect【详解】
句意：当谈到韩国时，人们总是把它和一些流行歌手联系到一起。connection是名词“联系，关联”；空格处位于主语之后充当谓语，需要填入动词的形式，connect是动词“连接，联系”；根据always可知，用一般现在时，并且people是复数名词，动词用原形。故填connect。
9．freezing【详解】
句意：我无法忍受中国北方寒冷的天气。空上需要形容词来修饰名词weather。freeze为动词，意为“冻结，冰冻”。freezing形容词，意为“极冷的”。故填freezing。
10．differences【详解】
句意：你能告诉我这两个单词之间的区别吗？所给提示词different是形容词“不同的”，根据“Can you tell me the … between the two words”可知，这里说的是你能告诉我这两个单词之间的区别吗，放在the后面跟名词形式，difference“区别、差异、不同”，可数名词，这里应用其复数形式。故填differences。
11．safety【详解】
句意：如今，中国人担心他们生活中的食品安全。根据“the…of”可知，此空应填名词，safe对应的名词是safety“安全”，故填safety。
12．meaning【详解】
句意：我不明白这句话的意思。mean“意味着”，动词。根据“I can’t understand the...of this sentence.”可知，此处是指句子的意思，空格应填名词。mean的名词形式为meaning“意思”，构成短语the meaning of...“……的意思”。故填meaning。
13．mine【详解】
句意：我可以用一下你的笔吗？我的笔出了点问题。结合所给提示词“I”，空格处指代“我的笔”，应该用名词性物主代词mine，此处相当于“my pen”。故填mine。
