共用题干第一篇California一A Land of Variety and ContrastCalifornia is a land of variety and contrast. Almost every type of physical land feature,sort of arctic ice fields and tropical jungles can be found within its borders.Sharply contrasting types of land often lie very close to one another. People living in Bakersfield,for instance,can visit the Pacific Ocean and the coastal plain,the fertile San Joaquin Valley,the arid Mojave Desert,and the high Sierra Nevada,all within a radius of about 100 miles. In other areas it is possible to go snow skiing in the morning and surfing in the evening of the same day,without having to travel long distance.Contrast abounds in California. The highest point in the United States(outside Alaska)is in California,and so is the lowest point(including Alaska).Mount Whitney,14,494 feet above sea level,is separated from Death Valley,282 feet below sea level,by a distance of only 100 miles. The two areas have a difference in altitude of almost three miles.California has deep,clear mountain lakes like Lake Tahoe,the deepest in the country,but it also has shallow,salty desert lakes.It has Lake Tulainyo,12,020 feet above sea level,and the lowest lake in the country,the Salton Sea,236 feet below sea level. Some of its lakes,like Owens Lake in Death Valley,are not lakes at all:they are dried up lake beds.In addition to mountains,lakes,valleys,deserts,and plateaus,California has its Pacific coastline,stretching longer than the coastlines of Oregon and Washington combined.Which of the following is NOT mentioned in the passage as being within a radius of about 100 miles of Bakersfield?A:The Pacific Ocean.B:San Joaquin Valley.C:Mojave Desert.D:Oregon and Washington.
After the mutiny, the captain of the merchant ship was left behind in some () island in the Pacific Ocean.A.residentialB.remoteC.riskyD.ridiculous

Hurricane winds blow in a large spiral（螺旋）around a relative calm center known as the"eye".The "eye" is generally 20 to 30 miles wide,and the storm may extend outward 400 miles.As a hurricane nears land,it can bring heavy rains,high winds,and storm surges（风暴潮）.The storm surges and heavy rainscan lead to flooding.2 Hurricanes are given a different label,depending on where they occur.If they begin over the NorthAtlantic Ocean,the Caribbean Sea,the Gulf 0f Mexico,or the Northeast Pacific Ocean,they are called hur- ricanes.Similar storms that occur in the Northwest Pacific Ocean west of the International Date line are called typhoons.Near Australia and in the Indian Ocean,they are referred to as tropical cyclones（龙卷风）.3 When a hurricane hits land,it can do great damage through its fierce winds,heavy rains,inland （内陆的）flooding,and huge waves crashing on to the shore.

问答题Practice 1 The greenhouse effect causes trouble by raising the temperature of the planet. The 1 rise is not very much，but the Earth’s ecosystem is very weak，and small changes can have large effects. It has been believed that this 2 of one degree will happen by the year 2025. This could probably 3 the North American corn belt, which produces much of the world’s grain， 4 to much higher food prices，and even less food for the Third World than they already have. However，it would also mean that some countries which are further north would be able to 5 crops they had never been able to before，although there is less land as you move north from the corn belt. The other serious worry is that rising sea levels from the melting of the polar ice could 6 flood many countries. A rise in sea levels of one meter，which many expels are 7 by the year 2100 (and some as soon as 2030)，would flood 15 percent of Egypt，and 12 percent of Bangladesh. The Maldives in the Indian Ocean would almost 8 disappear. Most of the countries which would suffer most from a rise in sea levels are the poor 9 states，so the islands in the Caribbean，South Pacific，Meditertgiiean and Indian Ocean have formed the Alliance of Small Island States，AOSIS，so they have a 10 voice in international politics and can make the richer developed world listen to their problems.[A] severely [B] damage [C] island[D] critical [E] grow [F] mainland[G] louder [H] predicting [I] rise[J] completely [K] geometry [L] actual[M] extending [N] 1eading [O] develop
