The iron structure contrasted（对比）sharply with the historic stone buildings of Paris. EiffePs four-legged iron archway was supposed to last only 20 years. Thafs when EiffePs permit to operate the building would expire（过期）and the city could choose to tear it down.Yet from the beginning. Eiffel had a strategy to save his building- If the Tower was linked to important research, he reasoned, no one would dare to take it down. So he would make it a grand laboratory for science.Scientific research began just one day after the Tower opened to the public on May 6, 1889. Eiffel installed a weather station on the Towerys third（and highest）floor. He connected instruments by wire to the French weather bureau in Paris. With these, he measured wind speed and air pressure.In 1903, still worried that his building might be torn down, Eiffel got a clever idea He asked the French military to conduct its own research on radio communications at the Tower. He even paid the armys costs.French army captain Gustave Ferrie worked from a little wooden house at the base of the Towers southern pillar From there, he made radio contact with forts around Paris. Convinced of the importance of radio communicationst the army set up a permanent radio station at the Tower. In 1910, the city of Paris renewed the structured permit for another 70 years.This year marks the iconic structured 125th birthday - Over the years, research conducted there has brought dramatic and unexpected payoffs. During World War L for instance, the French army used the Tower as a giant ear to receive radio messages. It even led to the arrest of one of the warfs most famous spies.21.

But many of the expressions using water have unpleasant meanings.The expression to be in hot watern is one of them. It is a very old expression. Hot water was used 500 years ago to mean being in trouble. One story says it got that meaning from the custom of throwing extremely hot water down on enemies attacking a castle.That no longer happens. But we still get in “hot water”. When we are in “hot water”，we are in trouble. It can be any kind of troubleserious or not so serious. A person who breaks a law can be in hot water with the police* A young boy can be in hot water with his mother if he walks in the house with dirty shoes.Being in deep water is almost the same as being in hot water. When you are in deep water; you are in a difficult position. Imagine a person who cannot swim being thrown in water over his head.

It probably comes from a way of testing the condition of a container. If it can hold water, it is strong and has no holes in it. If your argument can hold water，it is strong and does not have any holes. If it does not hold water, then it is weak and not worth debating*Throwing cold water” also is
