Passage FourEvery culture and every country in the world celebrates New Year, but not everyone does it the same way. The countries in North America and Europe welcome New Year on January the first. This practice began with the Romans in the Middle East, New Year is when spring begins. People in China and Vietnam celebrate it on the first day of the Spring Festival, which is the first day of their calendar based on the moon. Rosh Hashana, which is the Jewish (犹太人的) New Year, comes at the end of summer. The Hindus (印度教教徒 ) in India celebrate the first day of each season, so they have four New Years.In all these cultures, there is a practice of making noise. People made noise in ancient times to drive away the evil spirits (妖精) from their homes. Today making noise is more of a custom than a religious rimIn the United States, many people stay up until midnight on New Year's Eve to watch the clock pass from one year to the next. Friends often gather together at a party on New Year's Eve, and when the new year comes, all ring bells, blow' whistles, sing songs, and kiss each other. A favorite Scottish song which everyone sings together is Auld Lang Sync. The words tell of old friends and good times.In all cultures, New Year's Day is a time when people think of new beginnings. They want to make the coming year better than the last one. Many people in the United States make New Year resolutions. These are specific promises that they make to improve their behavior, change their habits, and become better people. There are many jokes about how a person keeps his or her New Year resolutions.48.

BThe word “day” has two meanings. When we talk about the number of days in a year, we are using “day” to mean 24 hours. But when we talk about day and night, we are using “day” to mean the time between sunrise and sunset. Since the earth looks like a ball, the sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place is moved from day into night and from night into day over and over by the spinning(旋转) of the earth. At the equator(赤道) day and night are sometimes the same length. They are each twelve hours long. The sun rises at 6 in the morning and sets at 6 in the evening. For six months the North Pole is tilted(倾斜) toward the sun. In those months the Northern Hemisphere(半球) gets more hours of sunlight than the Southern Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than night. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.56. When the Western Hemisphere is having day, the Eastern Hemisphere is having ______.A.both day and night B.day C.neither day nor night D.night

单选题Advertisement: The most flavorful olives in the world are kalamata olives. The more kalamata olives used to make a bottle of olive oil, the more flavorful the oil, and no company buys more kalamata olives than Zorba’s Olive Oil. Therefore, when you buy Zorba’s Olive Oil, you’re buying the most flavorful olive oil available today.  The reasoning presented in the advertisement is flawed because it overlooks the possibility that:ANot all of Zorba’s competitors use kalamata olives in their oil.BZorba’s sells more olive oil than any other company.CThe most flavorful olive oil is not necessarily the best olive oil.DBecause of bulk discounts, Zorba’s pays less per kilogram of kalamata olives than does its competitors.EThe number of kalamata olives harvested every year is far less than the number of Spanish olives harvested every year.

问答题Water is vital for our survival and for producing food. It takes about a thousand tons of water to produce one tone of grain that, fed to cows, produces only 18 pounds of meat. Today mankind is using about 160 billion tons more water each year than is being replenished by rain and fed back into water storages. If this water were carried in water trucks, it would require a 300, 000-mile-long convoy of trucks every day—a convoy length 37 times the diameter of the Earth. This is how much water we are using and not replenishing.
