All these situations make me 26 the purpose of traffic lights． 27 , it’s even more frightening to imagine letting people make their own decisions at 28 crossroads． Do the biggest cars get to go first? Who decides who goes next? So I guess I do like the idea of a system to 29 traffic． And I’ll do my best to 30 the traffic rules: to go, to be cautious, and to stop when I’m 31 to． It occurs to me that my 32 have done much the same for me 33 teaching me how to live． They have given me many 34 lights: to get along well with others, to listen and talk to them, to help others, and to 35 with joy and purpose． They have also given me some red lights 36 my life goes astray（誤入歧途） : not to be greedy, to keep my temper, and to control my desires． And there 37 have been some yellow caution lights: to watch how much I drink, to keep control of my behavior, and to 38 school regularly and work hard． If I obey these rules, my life will be as 39 as it can be． Just as I’m wise to pay attention to the traffic lights when I’m walking across the street, I’m wise to pay attention to the“ 40 signals” given to me by my parents． 21． A． suggests B． informs C． reminds D． warns 22． A． sight B． signal C． message D． switch 23． A． instant B． exciting C． dangerous D． cautious 24． A． notice B． sense C． remember D． feel 25． A． events B． problems C． situations D． accidents 26． A． think of B． wonder about C． care for D． worry about 27． A． Besides B． Anyway C． Instead D． However 28． A． noisy B． narrow C． crowded D． key 29． A． control B． direct C． improve D． serve 30． A． learn B． obey C． protect D． carry 31． A． supposed B． used C． devoted D． delighted 32． A． teachers B． friends C． leaders D． parents 33． A． in charge of B． in face of C． in terms of D． in danger of 34． A． safe B． green C． beneficial D． helpful 35． A． live B． share C． work D． municate 36． A． unless B． when C． before D． till 37． A． still B． even C． only D． also 38． A． start B． attend C． leave D． miss 39． A． good B． colorful C． meaningful D． healthy 40． A． traffic B． light C． life D． confidence 第二部分：閱讀理解 (第一節(jié) 20 小題。 A Scientists have long understood the key role that oceans play in regulating the Earth’s climate． Oceans cover 70 percent of the globe and store a thousand times more heat than the atmosphere does． What’s newer is the understanding of how this key ponent of our climate system responds to global warming． A brake on global warming—for now One of the ocean’s most important climate functions is absorbing heat and carbon dioxide （ CO2） , one of the gases that cause global warming． Acting as a heat sponge （ 海綿 ） , the oceans have absorbed huge amounts of heat and CO2 in the last forty years． The most recent scientific report from the Intergovernmental Panel on Climate Change （ IPCC） also notes with concern that the ocean is acidifying because of increased absorption of atmospheric CO2, and thus causing a threat for shellforming species． Sharp increases in carbon dioxide levels will cause further acidification of the ocean． Currents distributing heat Another important role the oceans play is that of distributor． Oceans deliver heat and lifesustaining nutrients around the globe． Just as blood vessels bring oxygen and nutrients to cells in the human body, the ocean’s currents carry oxygen, nutrients and heat throughout the Earth． The ocean distributes 25 to 50 percent of the energy the pla receives from the sun． For example, the Gulf Stream carries heat across the Atlantic． This warm current gives northwestern Europe a milder climate than it would normally have so far north． A change to the ocean’s circulation （ 循環(huán) ） patterns could throw Europe into a colder period, even as the rest of world experiences warmer temperatures． 41． We can infer from the passage that _____． A． the oceans cause global warming B． the oceans stop global warming C． the oceans release nutrients and heat D． the ocean ecosystems face more dangers 42． From the passage we can learn that the ocean’s currents _____． A． produce oxygen and nutrients everywhere B． absorb 25~50% of the energy from the sun C． distribute heat and nutrients around D． change the ocean’s circulation patterns 43． Which of the following is NOT the result of the ocean absorbing heat and carbon dioxide? A． It causes further acidification． B． It affects shellforming species． C． It makes the atmosphere hotter． D． It regulates the Earth’s climate． 44． This passage mainly talks about ______． A． the roles of oceans B． global warming C． ocean currents D． carbon dioxide B Maps and statistics can tell us a lot about where a country is headed.
