For many years, ships that wanted to travel from the Atlantic Ocean to the Pacific or from the Pacific to the Atlantic had to sail around South America. The trip took weeks and was very dangerous.

To make the route shorter and safter, it was decided to build a canal (运河). Panama was chosen because it is the narrowest country in the Americas. The French started building the canal as early as 1880, but their attempt failed after 21,900 people died of diseases and accidents. The Americans finally completed the project, and the Panama Canal opened in 1914. When the Panama Canal opened in 1914, ships were able to make the trip between oceans in approximately 10 hours. The locks in the canal have been called one of the seven wonders of the modern world.

The 48-mile-long Panama Canal was dug through the country of Panama. To pass between oceans, ships must actually go up. In fact, to travel through the canal, ships are raised 85 feet above sea level and then lowered again.

A ship enters the canal and sails to the first series of locks. Each lock is a huge compartment(分隔的空间) made of concrete walls and metal doors at each end. When one set of doors opens, the ship enters the lock. The doors close, and water flows into the lock, raising the ship until the water level equals the level in the next lock. At that time, the doors open to allow the ship to move into the next lock. When the doors close, the same process continues to raise the ship again. On either end of the canal, three sets of locks raise and lower ships. After the third lock, the ship enters Gatun Lake, sails about 23 miles, and begins its descent through the series of locks. To lower the ship, the locks work in reverse, allowing water to flow out of the lock until the water level is the same as the next lock. In this way, the ship reaches sea level and moves out into the ocean.

Over one million ships have passed through the Panama Canal since it opened. It has proven to be very important to world trade. In 2016, the canal was expanded to allow wider ships to pass through it, proving it will be a vital part of the world for many years to come.

1. Which of the following is the correct order of the events?
① The ship enters a lock.
② Water flows into the lock to raise the water level.
③ The doors close.
④ The doors open and the ship move out.

2. We can infer from the article that the Panama Canal ______.
A.is the narrowest canal in the worldB.was easy to construct
C.is an important link in global shippingD.will be closed in the near future
3. Which word in paragraph 4 probably means “a journey downward”?
A.reverseB.seriesC.processD.descent
4. According to the passage, the Panama Canal was built ______.
A.to shorten the trip between the Atlantic and Pacific Oceans
B.to raise and lower the water level in the locks
C.so that ships could travel to Panama from other countries
D.so that people could enjoy the beautiful view of Gatun Lake

【推荐1】Thailand’s capital Bangkok is both attractive and wonderful, a city of glass towers and concrete buildings crowded with nearly 10 million people. The ground beneath is spongy(松软多孔的) and moist. Imagine a brick resting on top of a birthday cake. That’s Bangkok-and it’s sinking into the Earth at an alarming rate.
Thailand’s disaster specialists have been warning of this coming disaster for years. One expert has said he’s worried about Bangkok resembling Atlantis. Another previously told Global post that the city will be under five feet of water by 2030. The latest estimates suggest that Bangkok is now sinking as fast as two centimeters per year in parts of the city. The predictions for 2100 are even more terrible. By then , Bangkok will be fully submerged and unlivable.
Like global warming, which will accelerate the city’s submersion by raising the sea leavel, Bangkok’s sinking problems are repeatedly _______But the monsoon season, currently underway, tends to bring this crisis to mind. A nasty storm can suddenly turn Bangkok’s streets into gushing streams. Sewers overflow, taxis move through dirty water and, occasionally, kids can pick up displaced fish.
Anond Snidvongs, director of the Southeast Asia Regional Research Center, predicts the city’s outskirts will be the first to go. Parts of the shoreline ebyong Bangkok are already liend with pumps that make noises and help to transform invading seawater. They don’t always work. During heavy rains, salt water flows in the streets of the city.
Bangkok is swallowed up a little more each day. Experts tend to offer two solutions. The first is to pu up a massive seawall that could cost nearly $3 billion-nearly 1 percent of Thailand’s current GDP. The second option is to give up entirely and move the capital to higher ground.
1. Why is Bangkok sinking into the earth?
A.Its buildings are too heavy.
B.It has an overlarge population.
C.Its underground is too loose.
D.It is resting on top of a lake.
2. What is the most likely meaning of the underlined phrase “shrugged off” in Paragraph 3?
A.ignored
B.valued
C.agreed
D.misunderstood
3. What information does Paragraph 4 express?
A.The optimism and wisdom shown by the city people.
B.The present serious situation Bangkok is faced with.
C.The weakness of the pumps to transform water.
D.The huge power produced by the surrounding seawater.
4. What’s the best title of the passage?
A.Bangkok is disappearing
B.The removal of Bangkok
C.Thailand’s capital needs a seawall
D.An attractive city under water
