18．It is so wet that the trees are extremely tall，some ______ over 90meters．（　　）
A．of them measuringB．of which are measured
C．of them measureD．are measured
2．There are three separate sources of danger in supplying energy by unclear power．
First，the radioactive material must travel from its place of production to the power station．Although the power stations themselves are strongly built，the containers used for the transport of the materials are not．Normally，only two methods of transport are in use，namely road or rail．Unfortunately，both of these may have an effect on the general public，since they are sure to pass near，or even through，heavily populated areas．
Second，there is the problem of waste．All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years．It is impossible to make these wastes nonradioactive，and so they must be stored in one of the inconvenient ways that scientists have invented．For example，they may be buried under the ground，or dropped into deserted mines，or sunk in the sea．However，these methods do not solve the problem，since an earthquake could easily break the containers．
Third，there may occur the danger of a leak or an explosion at the power station．As with the other two dangers，this is not very likely，so it does not provide a serious objection to the nuclear program．However，it can happen．
Separately，these three types of dangers are not a great cause for worry．Taken together，though，the probability of disaster is extremely high．

56．The author thinks that the ways to store nuclear wastes areB．
A．easy   B．ineffective   C．reasonable   D．impossible
57．What do we learn from the last paragraph？A
A．By itself，none of the three dangers is likely to cause worry．
B．The dangers of nuclear energy can certainly be avoided．
C．The general public are strongly against the nuclear program．
D．The power station itself is a very safe place．
58．What is this passage about？C
A．Uses of nuclear power．      B．Public anger at nuclear power．
C．Dangers from nuclear power． D．Accidents caused by nuclear power．
19．Air pollution is a leading cause of cancer and classified among top human carcinogens （致癌物质），said the International Agency for Research on Cancer （IARC），which is the World Health Organization's （WHO） cancer agency，on Oct 17，2013．"Our task was to evaluate the air everyone breathes rather than focus on specific air pollutants，"the IARC's Dana Loomis said in a statement．"The results from the reviewed studies point in the same direction the risk of developing lung cancer is significantly increased in people exposed to air pollution．"
    In 2010，lung cancer resulting from air pollution killed 223，000 people worldwide，and there was also convincing evidence that it increases the risk of bladder （膀胱） cancer．Loomis said people in Asia，Eastern North America，some places in Central America and Mexico，as well as North Africa have relatively high exposure（暴露）．Developing countries with large populations and booming manufacturing sectors，such as China，are particularly at risk．This week，Harbin，the capital city of Heilongjiang province，became the first Chinese city to officially suspendclasses due to serious smog，really good for teachers and students．
    Many developed countries face similar problems，although to a lesser（较少的、次要的） degree than most developing nations．Between 91 and 96 percent of Europeans living in cities are exposed to levels of PM2.5-tiny particles with a diameter of less than 2.5 micrometers-that are higher than the WHO safety limits．
    Although both the composition and levels of air pollution can vary dramatically from one location to the other，the IARC said its conclusions apply to all areas of the world．"Given the scale of the exposure affecting people worldwide，this report should send a strong signal to the international community to take action without further delay，"said Christopher Wild，director of the IARC．
60．What's the main task of IARC？B
A．To focus on cancer-causing substances．
B．To evaluate the air quality．
C．To study the developing risk of cancer．
D．To send signals to the international community．
61．The underlined word"suspend"in Paragraph 2 probably meansC．
A．accelerate         B．acknowledge            C．delay           D．decline
62．Why should the international community take action without further delay？A
A．A large number of people worldwide are exposed to air pollution．
B．More and more people in developing countries are exposed to air pollution．
C．Developed countries face air pollution，the level of which is higher than the safety limits．
D．The composition and levels of air pollution vary from place to place．
63．What might be the best title of the passage？D
A．PM2.5，bad effect．
B．Safety limits of air pollution．
C．Signals of air pollution．
D．Air pollution，cancer risk．
6．COPENHAGEN-The world is gathered in Copenhagen for the U．N．climate summit，but Denmark's bicycle-friendly capital has also given its name to a movement of cities trying to find a kinder way to travel to and from work．
Nearly 40 percent of Copenhagen's population cycle to work or school on ubiquitous（无处不在的） paved cycle paths．Many residents take to their bikes year-round，braving rain and snow through the winter in a city where the bicycles outnumber the people．
Amsterdam and Beijing too are known for their bicycles，but the Danish capital is where urban planners from around the world have been looking for ways to get their people out of cars and up onto bikes，an effort known as Copenhagenisation．
Klaus Bondam，Copenhagen's technical and environmental chief，calls himself a"mega cyclist"and says the bike's popularity stems partly from high taxes on cars which meant working-class Danes could not afford to drive in the 1930s and 1940s．"Today you'll meet everybody on the bicycle lanes-women and men，rich and poor，old and young．"Bondam said．
The local government has during the last three years invested more than 250 million crowns （$49.42 million） in bicycle lanes and to make the traffic safer for bicyclists．Today around a third of the population drive cars to work or study，another third take public transport，while 37 percent cycle--a figure the city aims to increase to 50 percent by 2015．
There are many benefits when citizens choose bicycles over cars：pollution and noise decline，public health improves，and more people on bikes or walking creates a sense of safety in the city．Fewer parked cars leaves more space for playgrounds，parks，shopping areas and other useful public places．
53．According to the first paragraph，Copenhagen is better known asB．
A．a city without cars                
B．a bicycle-friendly city
C．Denmark's capital                
D．the U．N．climate summit
54．We can learn from the second and the third paragraph，D．
A．there is no path for cars during rainy and snowy days
B．citizens are limited to have only one bike for each person
C．two-thirds of people in Copenhagen cycle to work or school
D．city planners try their best to encourage more citizens to ride bikes
55．Bikes are popular in Copenhagen partly becauseD．
A．the citizens are unable to afford to buy a car
B．the rich tend to keep fit by cycling to work
C．young people regard cycling a fashion to follow
D．high taxes were paid for cars in the 1930s and 1940s
56．We can learn from the passage thatC．
A．cars are forbidden to park in Copenhagen
B．more citizens tend to choose cars in Copenhagen
C．Copenhagen becomes a model for cities'traffic
D．living standards in Copenhagen are greatly declining．
16．TIJUANA，Mexico-A powerful earthquake swayed （摇动） buildings from Los Angeles to Tijuana，killing two people in Mexico，blacking out cities and forcing the evacuation （疏散） of hospitals and nursing homes．One California city closed off its downtown due to unstable buildings．
The 7.2-magnitude quake centered just south of the US border near Mexicali was one of the strongest earthquakes to hit region in decades．
"It sounds like it's felt by at least 20million people，"USGS seismologist Lucy Jones said．"Most of Southern California felt this earthquake．"
Sunday afternoon's earthquake hit hardest in Mexicali，a commerce center along Mexico's border with California，where authorities said the quake was followed by at least 20smaller aftershocks，including ones of magnitudes 5.1，4.5and 4.3．
"It has not stopped trembling in Mexicali，"said Baja California state Civil Protection Director Alfredo Escobedo on Monday．
Escobedo said one man was killed when his home collapsed just outside of Mexicali and another died when he rushed into the street in panic and was struck by a car．At least 100people were injured in the city，most of them struck by falling objects．Power was out in virtually the entire city．
Susan Warmbier was putting away groceries in the San Diego suburb of Chula Vista when her husband asked，"Is the house moving？"
Elsewhere in San Diego，there were reports of shattered windows，broken pipes and water main breaks in private buildings，but no reports of injuries，San Diego Fire-Rescue Department spokesman Maurice Luque said．Coronado Bridge over San Diego Bay was briefly closed as a precaution．
Across the border in Tijuana，Mexico，the quake caused buildings to sway and knocked out power in some areas．No tsunami warning was issued，but hundreds of people on Tijuana's crowded beach feared the worst and fled when they felt the ground shake．

3．Sometime early in the next century，human beings will move to Mars．They will live there for about a year，and then will be replaced with another group of pioneers．Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth．
We already know that Mars resembles the earth in many aspects：general size，presence of water，length of day，range of temperatures．These resemblances have caused many people to consider a centuries-long project：to terraform Mars．Terraforming means  altering a planet's surface so that Earth's life forms can survive there．This concept，previously found only in science fiction is now being seriously considered by scientists．
Terraforming Mars is theoretically simple：add nitrogen and oxygen to the atmosphere； pump water to the surface； and add the earth's plants and animals in the order in which they developed on Earth．But it will take at least 300years．
Some people think that such a project is too huge for humans to undertake，but there are very good reasons to make the attempt．The earth now contains some 6billion people，and no one has any idea of how many humans the earth can support．Our very existence and numbers are threatening many other species．We also have had some experience with terraforming our own planet：altering the landscape，the atmosphere and the climate．Currently terraforming earth has become a wiser activity as we try to control global warming，air and water pollution，and preserve some natural living places．
While the possibility of such a project is small，it is not impossible．Even if earth-bound societies come and go in the next 300years，the project can continue through the work of the Mars settlers without the need for constant backing from the earth．
The future existence of all the people in our world may very well depend upon our ability to terraform Mars．

63．What would be the best title for this passage？A
A．Terraforming Mars．        B．Saving the Earth．
C．Travelling to Mars．       D．A Newly-found Place．
64．What does the underlined word"altering"mean in the second paragraph？B
A．warming．          B．changing．
C．planting．         D．building．
65．According to the passage，the main purpose of terraforming Mars is toD．
A．do some scientific research work
B．find out its similarity to earth
C．avoid the dying away of many other species
D．find on Mars living place for the increasing human beings
66．The main reason for causing many people to consider terraforming Mars is thatA．
A．there are some resemblances between Earth and Mars．
B．terraforming Mars is theoretically simple
C．we have had some experience with terraforming our own planet：Earth
D．the development of science and technology is very rapid．
20．A Swedish man was dug out alive after being snowed in his car on a forest track for two months with no food，police and local media reported on Saturday．
The 45-year-old from southern Sweden was found on Friday，February17，too weak to say more than a few words．
He was found not far from the city of Umea in the north of Sweden by snowmobilers who thought they had come across a ruined car until they dug their way to a window and saw movement inside．
The man，who was lying in the back seat in a sleeping bag，said he had been in the car since December 19．
"Just incredible that he's alive considering that he had no food，but also since it's been really cold for some time after Christmas，"a rescue team member told regional daily Vasterbottens-Kuriren，which broke the news．Ebbe Nyberg，duty officer at the Umea police，said police saw no reason to doubt that the man had been stuck in the car for a very long time．
"We would not make up something like this．The rescue services were on site too and saw the same as us．"he told Vasterbottens-Kuriren．Umea University Hospital，where the man is recovering after being rescued by police and a rescue team，said in a statement he was doing well considering the circumstances．
Doctors at the hospital said humans would normally be able to survive for about four weeks without food．Besides eating snow，the man probably survived by going into a dormant-like（休眠似的） state，physician Stefan Branth told Vasterbottens-Kuriren．
"A bit like a bear that hibernates．Humans can do that．"he said．"He probably had a body temperature of around 31 degrees which the body adjusted to．Due to the low temperature，not much energy was used up．"
"Why the man ended up under the snow in the forest remains unknown，"police said．
24．Who found the Swedish man in the snow？A
A．Snowmobilers．B．The police．C．A rescue team．D．Local people．
25．"Police saw no reason to doubt that the man had been stuck in the car for a very long time．"Implies thatB．
A．police didn't think it true               
B．police were sure of the fact
C．police had some doubt on the fact      
D．police had reasons to doubt the fact
26．The reason why the man could survive was most probably thatC．
A．he was only forty-five years old       
B．he slept in the sleeping bag
C．he was in a dormant-like state
D．he did not use any energy
27．Which of the following can be the best title of the passage？D
A．A Traffic Accident                 
B．A Successful Rescue
