City life is not always a bad thing, but many experts worry about this process of urbanization (城市化 ). A new report says that process is having a huge effect on human health and the quality of the environment. Of the three billion people who live in cities now, the report says, about one billion live in unplanned settlements. These are areas of poverty, slums that generally lack basic services like clean water, or even permanent housing. More than 60 million people are added to cities and surrounding areas each year, mostly in slums in developing countries. The international community has been too slow to recognize the growth of urban poverty. Policy makers need to increase investments in education, health care and other areas.
The report talks about some successful efforts by local governments and community groups. For example, it says in Columbia, engineers have created a bus system that has helped reduce air pollution and improve quality of life.
The link between urban poverty and the environment is serious, but governments also need to consider why people are moving out of rural areas. Climate changes, droughts, floods—there are many reasons forcing people to leave their farm land.
The two issues of poverty reduction and the environment have existed side by side, but rarely have they connected—until now. Governments are starting to understand that environmental collapse is not a natural cost of economic development. Instead, it is hurting the possibility for growth.
The main idea of the passage is about ______.
A．urbanization and its effects
B．a huge effect of human
C．economic development
D．the environment
Researchers from the London School of Hygiene & Tropical Medicine said consumers were paying higher prices for organic food because of its imagined health benefits, creating a global organic market worth an estimated $48 billion in 2007.
A systematic review of 162 scientific papers published in the scientific literature over the last 50 years, however, found there was no significant difference.
"A small number of differences in nutrient content were found to exist between organically and conventionally (通常) produced foodstuffs, but these have nothing to do with public health, " said Alan Dangour, one of the report's authors.
"Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority . "
The results of research, which was commissioned by the British government's Food Standards Agency, were published in the American Journal of Clinical Nutrition.
Sales of organic food have fallen in some markets, including Britain, as a slowdown in economic growth has led consumers to cut back on purchases.
The Soil Association said that growth in sales of organic products in Britain slowed to just 1.7percent, well below the average annual growth rate of 26 percent over the last decade.
Why does organic food cost more than conventionally produced food？
A．Because people think they are much healthier.
B．Because they are more delicious.
C．Because people prefer organic food.
D．Because they sell better.
Population tends to grow at an exponential(指数的)rate. This means that they progressively double. As an example of this type of growth rate, take one penny and double every day for one month. After the first week, you would have only 64 cents, but after the fourth week you would have over a million dollars.
This helps explain why the population has come on "all of a sudden". It took from the beginning of human life to the year 1830 for the population of the earth to reach one billion. That repents(缓慢进行)a time span of at least two million years. Then it took from 1830 to 1930 for world population to reach 2 billion. The next billion was added by 1960, only thirty years, and in 1975 world population reached 4 billion, which is another billion people in only fifteen years.
World population is increasing at a rate of 9000 per hour, 220000 per day, and 80 million per year. This is not only due to higher birth rate, but to lower death rate as well. The number of births has not declined at the same rate as the number of deaths.
Some countries, such as Columbia, Thailand, Morocco, Costa Rica, and the Philippines, are doubling their population about every twenty-one years, with a growth rate of 3.3% a year or more. The United States is doubling its population about very eighty-seven years, with a rate of 0.8% per year. Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.
This passage chiefly discusses______.
A．the growth of world population
B．one type of the exponential rate
C．the population problem of more rapidly growing countries
D．the possible ways of dealing with the rapid population growth
In 2015, the US Forest Service for the first time spent more than half of its $5.5 billion annualbudget fighting fires－nearly double the percentage it spent on such efforts 20 years ago. In effect,fewer federal funds today are going towards the agency&39;s other work－such as forest conservation,watershed and cultural resources management, and infrastructure upkeep －that affect the lives of all Americans. Another nationwide concern is whether public funds from other agencies are going into constructionin fire-prone districts. As Moritz puts it, how often are federal dollars building homes that are likelyto be lost to a wildfire？
“It’s already a huge problem from a public expenditure perspective for the whole country, We need to take a magnifying glass to that. Like, “Wait a minute, is this OK ？”“Do we want insteadto redirect those funds to concentrate on lower-hazard parts of the landscape？ ” Such a view would require a corresponding shift in the way US society today views fire, researcherssay.
For one thing, conversations about wildfires need to be more inclusive. Over the past decade, thefocus has been on climate change－how the warming of the Earth from greenhouse gases is leadingto conditions that worsen fires. While climate is a key element, Moritz says, it shouldn’t come at the expense of the rest of theequation.
“The human systems and the landscapes we live on are linked, and the interactions go both ways,"he says. Failing to recognize that, he notes, leads to "an overly simplified view of what the solutionsmight be. Our perception of the problem and of what the solution is becomes very limited. At the same time, people continue to treat fire as an event that needs to be wholly controlled andunleashed only out of necessity, says Professor Balch at the University of Colorado. But macknowledging fire&39;s inevitable presence in human life is an attitude crucial to developing the laws,policies, and practices that make it as safe as possible, she says.
“We’ve disconnected ourselves from living with fire, ” Balch says. “It is really important tounderstand and try and tease out what is the human connection with fire today. ”

A.exhausted unprecedented management efforts
B.consumed a record-high percentage of budget

C.other factors should not be overlooked
D.a shift in the view of fire has taken place
The overly simplified view Moritz mentions is a result of failing to _____.A.discover the fundamental makeup of nature
B.explore the mechanism of the human systems
C.maximize the role of landscape in human life
D.understand the interrelations of man and nature
Moritz calls for the use of "a magnifying glass" to _____.A.raise more funds for fire-prone areas
B.avoid the redirection of federal money
C.find wildfire-free parts of the landscape
D.guarantee safer spending of public funds
Professor Balch points out that fire is something man should _____.A.do away with
B.come to terms with
C.pay a price for
D.keep away from

The importance of saving gas, then, cannot be stressed too much. Let's say, for instance, that the fuel used by each car could be cut back just 15 percent. This could be done by making fewer trips each day. It could be done through better driving habits. If it were done, our nation's use of fuel would fall by close to two-thirds of a million barrels per day.
We can all help save gas. One way is to ride the buses. Some of us could walk to work. We could ride mopeds(机动脚踏两用车) or bikes. Another way is to share a ride. We could join carpools (合伙使用汽车). About one-third of all cars are used for going to and from work.
Go shopping with a friend from time to time. If two people use a car instead of one, we all save. There would be fewer cars on the road. The savings on gas around the nation would come to more than one half million barrels a day.
Another way to save is by cutting our useless trips. Can you find one car trip per week that could be handled by telephone？ Can you combine trips？ If each car took one less 10-mile trip a week, we could save three-and-half billion gallons of gas a year. This comes to nearly 5 percent of the total passenger car demand for gas.
The way people drive decides how much fuel they save. Careful drivers may get20 percent more miles per gallon than normal drivers. They could get 50 percent more miles per gallon than wasteful drivers. Careful drivers obey the 55-mile-per-hour speed limit. They get to their desired speed quickly and keep a steady pace.
If just one gallon of gas were saved each week for each car in the country, we could all save about five-and-half billion gallons a year.
To decrease the number of useless car trips, you can use the ______.
A．bus service
B．subway service
C．telephone
D．airplane
Who is going to feed all these people？ Where is the food going to come from？ Are we going to have enough food？ Are we going to produce more artificial foods？
One way of improving the situation is for people to eat less meat. Why？ Because it takes 4 kilos of grain protein (蛋白质) to produce half a kilo of meat protein.Clearly, there is not going to be sufficient meat protein for 8 billion people. Therefore, it will also be necessary to change eating habits because meat is the main part of many people's food today.
A possible solution to this latter problem is the soybean (大豆). The soybean plant produces beans which have a very high fat and protein content. Scientists can now make these look and taste like real meat. They can also make many other artificial products such as soybean milk, for example, which has a taste of milk and can be used in cooking in very much the same ways as cow's milk. In fact, one woman in the United States fed her family only on soybeans for a year! She gave them soybean beef, soybean chicken, soybean mi]k, and sometimes just soybeans. Possibly, we are all going to eat soybeans in the future and finally give up meat completely from our tables.
What is the main subject of the passage？
A．A solution to man's food problem.
B．A solution to the population problem.
C．Advantages of soybean.
D．How to develop good eating habits.
The American love of sports (11) to a pitch never before known. (12) the middle of the century we were practically without sports and even until some fifteen years ago there (13) very little enthusiasm aroused by sports (14) the fever that has within the past decade and a half swept over the country.
(15) the passionate fervor has been increasing，and the coming season promises to be the most enthusiastic of all.
(16) England the Romans brought their sports；then the Saxons and the Normans added others，and there were football matches and archery games.
In 1618 King James I issued a book of sports stating what sports were (17) after church service on Sundays；but intense anger was (18) among those who strictly observed the principles of the Bible，and in 1644 the Long Parliament ordered the book (19) by the public executioner，and all sports forbidden or strongly (20) .
A. have raised
B. has raised
C. have risen
D. has risen
Surrounding the earth was an unbroken canopy of clouds miles thick and made up mostly of water vapor. Rain falling toward the still-hot earth was heated to steam and rose to the clouds again. After many millions of years, as the earth continued to cool, its surface temperature fell below the boiling point of water. Rainwater could now remain on the earth, covering its whole surface except for the higher places on earth that had been formed from the lighter rock materials.
In 1970, scientists had pieced together evidence that the lighter rock materials had formed one huge continent by a vast ocean. Then, about 200 million years ago, the great continent began to break up, the pieces moving slowly apart.
The onrushing waters of the single huge ocean now entered and filled the spaces between the separating continents--and became the several oceans and seas we know today.
This passage mainly talks about ______.
A．the origin of the earth
B．the origin of the ocean
C．the history of the earth
D．the forming of the earth's crust
