‎2019高考英语二轮（阅读理解）金品训练（02）及解析 A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below ‎16℃‎.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere，warming the rest of the world.Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.‎ In the past hundred years, humans have begun destroying rainforests in search of three major resources (资源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.‎ There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.‎ Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.‎ ‎[语篇解读]　文章论述了热带雨林旳重要作用以及对环境旳影响.‎ ‎1．Rainforests can help to adjust the climate because they________.‎ A. reflect more heat into the atmosphere B. bring about high rainfall throughout the world C. rarely cause the temperature to drop lower than ‎‎16℃‎ D. reduce the effect of heat from the sun on the earth ‎[解析]　因果判断题.由文章第一段内容可以得出答案.‎ ‎[答案]　D ‎2．What does the word “this” underlined in the third paragraph refer to?‎ A.

However, the historical contribution from aviation emissions to global warming is more than doubled the contribution from road emissions．In fact, over the next 100 years, today ' s road emissions will have a climate effect that is four times higher than the climate effect from today ' s aviation emissions．‎ ‎ For shipping, the picture is more complicated．Until now, shipping has had a cooling effect on climate．This is because shipping produces a large amount of SO2, which has a cooling effect．However, although the gas, until now, has given the shipping industry a cooling effect, this effect will disappear after a while, as the gas doesn't last long in the atmosphere．The long-lived CO2, will dominate （占优势）, giving shipping a warming effect in the long run．‎ ‎ In general, the transport sector' s contribution to global warming will be continuously high in the future．‎ ‎45．What can we learn about road traffic?‎ ‎ A．It has the second largest warming effect on climate．‎ ‎ B．It produces 15% of all CO2 into the air every year．‎ ‎ C．It created more CO2 emissions than aviation in history．‎ ‎ D．Its CO2 emissions will probably increase in future．‎ ‎46．Shipping has a cooling effect because ______．‎ ‎ A．shipping conditions have been improved ‎ B．the amount of ships at sea is small ‎ C．it produces a gas which has a cooling effect ‎ D．the gas it produces can absorb CO2‎ ‎47．The underlined phrase in paragraph 4 probably means"______"．‎ ‎ A．after a long time B．in a tiring race ‎ C．all the time D．during a long voyage ‎48．The passage mainly talks about______．‎ ‎ A．the effect of CO2 on global climate ‎ B．the effect from traffic on global warming ‎ C．how to choose a green way to travel ‎ D．why transport produces so much CO2‎ C ‎ At a recent class, yoga instructor Hagen taught several facial exercises designed to build up facial muscles．Some women practise moves including "The Lion" , showing the tongue hanging out and eyes rolled up．Hagen encourages class members to hold the position for 60 seconds, joking．"You can do this any time．It really helps you get a seat on the train．"‎ ‎ Hagen recently published a book—The Yoga Face: Remove Wrinkles （皱纹） with the Ultimate Natural Facelift．She developed a workshop using facial yoga because women wanted to look their best．‎ ‎ Facial muscles become weak and flabby （松驰旳） and need regular exercise to reduce wrinkles．Besides "The Lion", other exercises include "Satchmo" ．in which the cheeks are blown out Louis Armstrong-style, and "Marilyn", in which attractive ‎ kisses are blown to strengthen mouth muscles for full and firm lips．‎ ‎ Hagen recommends facial yoga for those wanting to find outer and inner beauty, saying, "The emotional aspect is just as important as the physiological （生理学旳）."‎ ‎ But she doesn't rule out plastic surgery or Botox．"I don' t rule it out for myself．One day I may feel like I need that．But regardless of that, maintaining elasticity （弹性旳） is extremely important, especially if you have had Botox and plastic surgery," she said．‎ ‎ While making faces in front of strangers might frighten some, those who attended the class thought it the perfect way to fight against busy New York lifestyles．" Working in New York is very stressful．" Kathy Healey said, "It's a perfect way to end the week．"‎ ‎49．By saying, "It really helps you get a seat on the train"．Hagen means that some passengers can .‎ ‎ A．practise yoga with you B．help you do facial yoga ‎ C．be frightened away D．notice your face ‎50．Some women are turning to facial yoga because they ______．‎ ‎ A．want to escape working stress B．want to have a new lifestyle ‎ C．can practise it anywhere D．want to look best ‎51．Which of the following about facial yoga is TRUE?‎ ‎ A．It is designed for wealthy people． B．It can be useful but harmful．‎ ‎ C．It can make you feel at ease． D．It is popular in the world．‎ ‎52．From the passage we can conclude that plastic surgery and Rotox ______．‎ ‎ A．help reduce wrinkles B．are good for women's health ‎ C．will be replaced by facial yoga D．are natural ways to keep young D For more than twenty years scientists have been searching for signs of life on other planets．Most of these searches have been done over the radio．The hope is that someone in outer space may he trying to get in touch with us．Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive to such messages．‎ ‎ Scientists are using powerful radio telescopes （望远镜） to listen to signals from about 1，000 stars, all within 100 light years of earth．In addition, they will scan （扫视） the entire sky to "listen" for radio messages from more distant stars．Using a computer, they will be able to monitor more than eight channels at one time．Scientists are looking for any signal they stands out from the hack-ground ‎ noise．‎ ‎ Of the 200 billion stars in the Milky Way galaxy （银河星系）, scientists find that five percent are like our sun．Perhaps half of them have a planet like our earth．Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution of life．Based on the inhabitable（ that can be lived in） planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life．‎ ‎ However, many scientists wonder whether intelligent life exists on other planets．Some believe that twenty years of searching without any intelligible messages shows that no one is out there．They say that the evolution of intelligence comparable to ours is unlikely．‎ ‎ Other scientists believe that our search hasn't been long enough to rule out the possibility that intelligent life exists in our galaxy．Although our sun family is only about five billion years old, our galaxy is about 20 billion years old．In that time, some scientists think it is likely that civilization （文明）much more advanced than ours have developed．Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us．If we hope to find intelligent life, these scientists believe that we have to keep looking．‎ ‎53．According to the passage, how many planets in our galaxy might be inhabitable?‎ ‎ A．5 billion． B．10 billion． C．15 billion． D．200 billion ‎54．The first paragraph in this passage is mainly about ______．‎ ‎ A．how scientists are looking for signs of life on other planets ‎ B．why scientists are looking for signs of life on other planets ‎ C．where scientists are looking for signs of life on other planets ‎ D．when scientists are looking for signs of life on other planets ‎55．The underlined word "monitor" in the passage means "______"．‎ ‎ A．find B．follow C．check D．form ‎56．Which of these statements is true based on the information in the passage?‎ ‎ A．The earth is one of the oldest planets in our galaxy．‎ ‎ B．Most scientists believe that there is intelligent life on other planets．‎ ‎ C．Scientists are trying different ways to find signs of life on other planets．‎ ‎ D．Scientists don' t believe that there might be life on other planets．‎ E ‎ How to protect children Web fans from unsuitable material on-line while encouraging them to use the Intel-net has long been discussed in the U．S．‎ ‎ For some parents, the Internet can seem like a jungle, filled with danger for their children．But jungles contain wonders as well as dangers and with good guides, some education, and a few precautions （预防措施）, the wilds of the Internet can be safely navigated （航行） ?"Kids have to be online．If we tell our kids they can't have access（机会） to the Internet, we' re cutting them off from their future, " said an expert．‎ ‎ Most kids have started to use search engines．Many of them are great for finding ‎ tons of interesting Internet sites, and they can also locate places where you might not want your kids to go．There are search engines designed just for kids．A certain software contains only sites that have been selected as safe．The most popular way to limit access would he to use what is known as a "content screener（过滤器）"．But this can' t be wholly reliable（可靠）, and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet．Another way is that mum or dad is nearby when the child is surfing（浏览） the Internet．‎ A few other tips ‎ ●Don't put the PC in a child' s．room but keep it in an area where mum or dad can keep an eve on things．That also makes the Internet more of a family activity．‎ ‎ ●Ask your child what he or she has been doing and about any friends they make on-line．‎ ‎ ●Tell your child not to give on-line strangers personal information, especially like address and phone number．‎ ‎ ●And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along．‎ ‎57．The passage is mainly about the subject of______．‎ ‎ A．American children going on-line ‎ ‎ B．Internet in ‎America ‎ C．appreciating Internet ‎ ‎ D．opposing children's on-line ‎58．The best way to protect children from improper material is ______．‎ ‎ A．to install （安装） a content screener on the computer ‎ B．to buy some search engines for the children ‎ C．to he nearby when they are surfing the Internet ‎ D．to talk to the children and persuade them to tell right from wrong ‎59．Which of the following is right according to the passage?‎ ‎ A．Surfing the Internet is the best method of educating children．‎ ‎ B．Children' s not having access to Internet may have effect on their progress．‎ ‎ C．Using a content screener is most reliable for keeping children having access to Internet．‎ ‎ D．Searching engines can help children to select materials fit for them．‎ ‎60．According to the passage, we can infer that ______．‎ ‎ A．soft wares fit for children want programming ‎ B．a child who is on-line is in danger ‎ C．Internet is a jungle full of danger ‎ D．Internet contains a lot of harmful sites 参考答案
