     Traveling without a map in different countries, I find out about different "styles"(方式) of directions

(方向)every time I ask "How can I get to the post office?"

     Foreign tourists are often confused (迷惑的) in Japan because most streets there don't have name

signs; in Japan, people use landmarks(地标) in their directions instead of street names. For example,

the Japanese will say to travelers, "Go straight down to the corner. Turn left at the big hotel and go past

a fruit market. The post office is across from the bus stop."

     People in Los Angeles(洛杉矶), the US, have no idea of distance on the map: they measure (衡量)

distance (距离)by time, not miles. "How far away is the post office?" you ask. "Oh," they answer, "it's

about five minutes from here." You don't understand completely, "Yes, but how many miles away is it,

please?" To this question you won't get an answer, because most probably they don't know it themselves.

     People in Greece(希腊) sometimes do not even try to give directions because tourists seldom

understand the Greek language. Instead, a Greek will often say, "Follow me." Then he'll lead you through

the streets of the city to the post office.

     Sometimes a person doesn't know the answer to your question. What happens in the situation? A

New Yorker might say, "Sorry, I have no idea." But in Yucatan, Mexico, no one answers "I don't

know." People there believe that "I don't" is impolite. They usually give an answer, but often a wrong

one. So a tourist can get lost very easily in Yucatan!

     However, one thing will help you everywhere in the world. It's body language.

1. Which one of the following is probably an example of Japanese directions?

A. "Go south two miles. Turn west and then go another mile."

B. "Turn right at the hospital and go past a school. The library is right in front of you."

C. "The post office is about five minutes from here."

D. "The post office is at Street Kamira."

2. People in Los Angeles don't give directions in miles because ______.

A. they use landmarks in their directions instead of distance

B. they prefer to lead you the way

C. they often have no idea of distance measured by miles

D. they prefer to use body language

3. Greeks give directions by ______.

A. using street names

B. using landmarks

C. leading people the way

D. giving people a wrong direction

4. Where is Yucatan?

A. In the USA.

B. In Japan.

C. In Greece.  

D. In Mexico.

5. Which of the following is NOT true?

A. People in Yucatan always give right directions.

B. There are different ways to give directions in different parts of the world.

C. People in some places give directions in miles, but people in other places give directions in time.

D. A person's body language can help you understand directions.

兴趣小组同学为了探究实验室中久置的氢氧化钙固体的成分,进行了有关实验。请你与他们一起完成以下探究活动:

【对固体猜想】猜想Ⅰ.全部是Ca(OH)2

猜想Ⅱ.全部是CaCO3

猜想Ⅲ._______________。

【实验】小明同学取固体样品于试管中,加少量水,振荡,静置,发现有白色沉淀出现,他认为氢氧化钙已发生变质。小红同学提出质疑,认为小明的实验不足以说明氢氧化钙已变质。其理由是_______________。小雯同学设计了如下实验方案:

【判断】(1)若现象a为有气泡产生,说明沉淀A中含有的物质名称是__________。

(2)若X是CO2气体,现象c无白色沉淀,则说明样品中______(填“有”或“没有”)Ca(OH)2。综合(1)和(2)的结论,得出猜想_______成立。

(3)若X是Na2CO3溶液,猜想Ⅲ成立的实验现象是:现象a为有________产生,现象b为无色酚酞试液______色,现象c为____________。产生现象c的反应的化学方程式为________________。

【拓展】若(3)反应后的废液直接倒入下水道,会污染环境。小雯同学用适量稀硫酸处理废液,但不知是否恰好完全中和。于是,小强同学设计了如下实验方案来验证:

【反思】①有同学提出质疑,认为上述实验方案不足以证明处理后的废液一定显中性,理由是:______________。为此,还需要从以下选项中选择一种试剂再进行实验验证,其中可行的是______(填字母)。

A、石蕊溶液 B、Ba(NO3)2溶液 C、锌粒 D、生锈的铁钉

②久置的氢氧化钙变质的化学方程式是_________________。
