People have their own ways of saying things with their own special expressions. Some of these expressions are easy to understand. “As Easy as Falling off a Log (圆木)” is one such expression. It describes a job that does not take much effort. If you ever tried to walk on a falling tree log, you may understand what the expression means. It is easier to fall off the log than to stay on it.

There are several other expressions that mean the same thing. And their meaning is as easy to understand as falling off a log. One is “Easy as Pie.” Nothing is easier than eating a piece of sweet juicy pie, unless it is a piece of cake. “A Piece of Cake” is another expression that means something is extremely easy to do.

Another expression is “As Easy as Shooting Fish in a Barrel (桶)”. Clearly, fish in a barrel will be much easier to shoot than fish in a river. In fact, it would be as easy as falling off a log.

Sometimes, things that come to us easily also leave us just as easily. In fact, there is an expression “Easy Come Easy Go”. Another easy expression is “To Go Easy on a Person”. It means to treat a person kindly or gently, especially in a situation where you might be expected to be angry with him. A wife might ask her husband to go easy on their son, because the boy did not mean to destroy the toy. If you want to borrow some money to fix the car, you should look for a friend who is an “Easy Touch”. An easy touch or a soft touch is someone who is kind and helpful.

And there is one more expression that means do not worry or work too hard. Try to keep away from difficult situations. “Take it easy”, until we meet again.

Japan's 24-hour convenience stores, already struggling with lagging sales and growth, may soon face yet another threat - moves to limit business hours and close the stores late at night. The district of Saitama, which borders Tokyo, may follow in the footsteps of the western city of Kyoto and urge convenience stores to close during late night hours in an effort to limit carbon dioxide(二氧化碳)emissions, Japanese media reported.

Kyoto, a former capital, wants to persuade convenience and other 24-hour stores to close late at night so as to improve evening views of the city and cut down on energy use. The Nikkei business daily said closures could last from 11 p.m. to 7 a.m. The move is strongly opposed by the industry, which fears a bad impact on an already troubled sector also grappling with the specter of a higher tobacco tax, which could hit overall sales.  

"Even if we only operate the stores for 16 hours, we can't stop the refrigerators," said Toshiro Yamaguchi, the president of Seven-Eleven Japan Co, which is owned by Seven & I Holdings Co Ltd, at a news conference in Saitama on Tuesday. He said such cuts in operating hours would reduce each store's profit by 20 percent. "If this happens, our current business model will lose its foundation."  

Analysts said that while it is difficult to estimate the potential impact of the move without a concrete plan, their overall impression was that it was likely to be negative. "This could cut profits and lead to less efficient operations and the increased loss of opportunities," said Masafumi Shoda, an analyst at Nomura Securities. "But it depends on the store -- urban stores do better than others. There are some in the countryside that are inefficient."  

Some have suggested that if governments were sincere about reducing carbon emissions there were much more efficient methods, such as cutting back on the huge number of automatic vending machines(自动售货机)

68. Which of the followings was the first to try to limit convenience store hours?

69. What's the main goal of the proposal?  

A. To give employees more free time.  

B. To limit carbon dioxide emissions.  

C. To sell more tobacco products.  

D. To reduce each store’s profit.  

70. How's the convenience store sector doing in Japan?  

A. It is not mentioned.  

B. It's doing great. Business is booming.  

C. Not very well.  

D. It’s about to close.
