Mr. and Mrs. Smith have just opened a small restaurant. In order to attract customers. they put a notice in front of the restaurant, which said, “Meals on the house for three days.”

A foreign student who didn’t know much about English passed by the restaurant on the second day. It was lunch time and he felt hungry. “Well. Here is a restaurant. I’m going to have something to eat.” he said.

He saw the notice when he walked toward the restaurant. “American people are really strange. They even eat dinner on the house! But how can I get onto the top of the house?” he asked himself.

He looked around and found a ladder against a tree nearby. He was very glad. But as he reached the top, he heard someone shouting at him, “Hey, what are you doing up there?” Mr. Smith was looking at him angrily. Beside him was a policeman.

“Doesn’t your notice say ‘Meals on the house for three days’? Just a joke?” the foreign student answered. On hearing that, both Mr. Smith and the policeman burst into laughter（开怀大笑）. Do you know the meaning of “on the house”? In fact, it means “something is free for the customers”.

Hundreds of millions of dollars worth of goods（商品）flow throw the Suez Canal（苏伊士运河）every hour, according to CNBC. The canal is one of the most important parts of the global shipping network that all of us depend on.

However, the ship Ever Given got stuck in the river on March 23, 2021 because of high winds. It was stuck there for six days until finally being freed on March 29. But during that short time, the ship blocked the canal, leaving at least 422 ship unable to pass. It showed us just how big of a role the canal plays in world trade.

The canal connects the Mediterranean（地中海）and Red seas. It creates a shorter route between Europe and the India and western Pacific oceans. By using the canal, shipping companies can move goods between Europe and Asia without having to sail around Asia, reducing voyage distance（航行距离）by about 7,000 km. This allows us to move goods faster and cheaper than shipping by air.

All kinds of goods get shipped through the canal every day. About 7 percent of the world’s oil is carried through the canal, as well as 30 percent of the world’s total shipping container freight（集装箱货运）. Even basic daily goods like toilet paper and coffee pass through the canal, according to USA Today. If the canal is blocked for a long time, there might be shortage of these goods, which can cause their prices to go up.
