Passage 1
The Pacific Ocean covers more than 166 million square kilometers (more than 64 million square miles) --about one-third of the earth’s surface. The area of the Pacific is greater than that of all of the continents combined, and it makes up nearly half of the area covered by the earth’s oceans.
The Pacific is not only the largest ocean but also the world’s oldest and deepest, with an average depth of 4,280 meters (14,040 feet). Most of the geologic activity of the Pacific occurs around its edges. In fact, the so-called Pacific Ring of Fire contains more than 80 percent of the earth’s active volcanoes and most of its earthquake activity.
The Pacific was given its name because of the tranquillity(安静) of its waters, although it is occasionally swept by typhoons, and a number of strong currents circulate beneath the surface. The influence of the icy Antarctic continent and the smaller ratio of land to sea lowers
A. a little
B. greatly

More than one hundred thousand international students will spend this summer working and traveling in the United States. They are participating in the Summer Work Travel program through the State Department. They receive J-I exchange visitor visas.
The idea is for students to work for up to three months and earn enough money to then spend a month traveling before they return home.
The Exchange Visitor Program, aims to increase global understanding through educational and cultural exchanges.
The Summer Work Travel program has existed for years. This year there are some changes. The State Department recently amended the employment rules. These changes follow a strike last summer by foreign students working at a distribution center for Hershey’s chocolates.
The State Department said the students were put to work for long hours in jobs that provided little or no contact with the outside world. The students complained about having to lift heavy bo
