According to a report by the United Nations，5...

According to a report by the United Nations，54 percent of the world’s population lives in urban areas and it predicts that by 2050，this figure will have increased to around 70 percent.But as more and more people migrate from the countryside to the city to get better opportunities，they can end up with nowhere to live.

This is true in places such as Rio de Janeiro，where migrants can’t rent or buy a home，and they end up building their own communities and houses on unoccupied land.These are called shanty towns—poor communities where the houses are built out of cheap materials—and often don’t have any electricity or water supply.

These are，of course，not the megacities(大城市)of the future we want to see. Some serious urban planning is needed to make our cities of the future good，safe and modern places to live in. This involves improving the infrastructure(基础设施)，the housing conditions and also the opportunities for education and employment.

Something urban planners are looking at now is the creation of “smart cities”. According to John Rossant，founder and chairman of the non-profit organization New Cities Foundation ，technology is the way forward.He thinks that it’s generally accepted that“cloud computing, ubiquitous internet，robust 5G networks,etc，will transform our cities.” He says technology is really “a game changer” in urbanisation. It would collect large amounts of data about how a city is performing and may improve how a city functions.

This may sound like a utopian(乌托邦似的)view. For now，some big cities around the world are trying out more low—tech schemes to try and make them desirable places to live and work in. Building shared—ownership housing and improving public transport are some ways. And encouraging cycling and building bike lanes can keep the population healthy and cut down on smog. What would make your city a better place to live in?

According to a study by SallieMae, 84 percent of undergraduate students have credit cards, and by the time they are seniors, they have accumulated US $ 4,100 in debt, on top of whatever student loans they may have taken out．

Credit cards are the most convenient form of payment, and they are aggressively marketed to college students．Reportedly, a typical college student carries 4．6 credit cards and US $ 3,173 in credit card debt．

Credit cards seem to be a fact of life, not just student life． In the long term,  using a credit card properly and paying off the balance can help establish a card history and increase your credit score, which will come in handy when you need an important loan, for a house or car, for example．Your credit score can affect even unrelated things like insurance rates．Credit cards also offer more protection for users than debit cards（借记卡）．Under federal law, the credit card holder is only responsible for the first US  $ 50in fraudulent（欺诈的） purchases in cases of theft or loss．However, debit card users are responsible for the first US $ 500．

SallieMae found some good news in the fact that two thirds of students had discussed credit issues with their parents, but 84 percent said they needed more information．Those who didn't get any guidance were more likely to be surprised when they found out how much they owed．

While credit cards offer the easiest access to money, they make it easy to live outside your means．Less than a fifth of students surveyed paid off their balance every month, and carrying a balance brings finance charges, sometimes at a very high interest rates．

SallieMae found that almost 40 percent of students chose their first credit card based on direct mail, which is probably why students get credit card offers in the mail． But when the credit card offers flow in, be sure that you read the fine print．Offers of low or no interest rates can disappear, leaving you a debt that climbs beyond your ability to pay it off．

1.What does the first paragraph imply?

A．Most of the senior students are shocked to see how much they owed．

B．Students can only take out loans from credit cards．

C．Most of students' loans come from credit cards．

D．Credit cards have a bad effect on college students．

2.The underlined part "come in handy" in the third paragraph probably means “________ ”

A．bring trouble                          B．make mistakes

C．be important                           D．be useful

3.According to SallieMae, what is the possible reason why students get so many credit card offers in the mail?

A．Many students' first credit card is based on direct mail．

B．it costs the banks little to mail out credit cards．

C．Students don't like to go to the bank to open a credit card account．

D．Banks have no other way to let students use their credit cards．

4.What is the theme of the third paragraph?

A．The advantages of using debit cards．

B．The similarities between credit cards and debit cards．

C．The advantages of using credit cards．

D．Credit cards are the most convenient form of payment．

5.According to SallieMae, how many students had not discussed credit issues with their parents?

A．l/3               B．2/3              C．l/4               D．3/4

Finland is the happiest place on Earth, according to the 2018 World Happiness Report of 156 nations.

The report, released Wednesday by the United Nations’ Sustainable Development Solutions Network, ranks the countries of the world based on six different categories of well-being: income, freedom, trust, life expectancy, generosity and social support. This year's report also pays special attention to the happiness of each country’s immigrants.

The U.S. dropped four spots from 2017 and landed in 18th place, and last year’s winner, Norway, came in second place — followed by Denmark, Iceland and Switzerland.

“The top five countries all have almost equally high values for the six factors found to support happiness, and four of these countries—Denmark, Switzerland, Norway and now Finland — have been in first place in the six World Happiness Report rankings since the first report" in 2012, ”co-editor John Helliwell told CNN.“In a division with such excellent teams, changes in the top spot are to be expected."

Rounding out the top 10 happiest countries was Canada in sixth place, then New Zealand, Sweden and Australia. The order of the top 10 nations changed from the 2017 list but the countries did not, according to the report. They were also 10 of the 11 top spots in the immigrant happiness category (including Mexico — 24th overall, but 10th in immigration).

“The most striking finding of the report is the remarkable consistency between the happiness of immigrants and the locally born,” Helliwell said in a statement. “Although immigrants come from countries with very different levels of happiness, their reported life evaluations resemble those of other residents in their new countries. Those who move to happier countries gain, while those who move to less happy countries lose.”

Other major world powers placed in significantly low spots on the list. Germany came in 15th, the UK was 19th — followed by Japan in 54th place, Russia in 59th and China in 86th.

The report, based on surveys completed by citizen volunteers, came just under a week before World Happiness Day on March 20, when the UN declared to recognize “the relevance of happiness and well-being as universal goals and aspirations in the lives of human beings around the world and the importance of their recognition in public policy objectives”

1.The US ranked______ in 2017.

A. 14 B. 10

C. 18 D. 22

2.What is the most significant finding of the report?

A. That immigrants are different from residents in the country.

B. That immigrants come from countries with different levels of happiness.

C. That immigrants become happy when they leave the country.

D. That immigrants and locals feel the similar level of happiness.

3.What can be inferred from the last paragraph?

A. Happiness is no less important than any other aspect in life.

B. People’s happiness and well-being should be considered when it comes to policy-making.

C. The happiness report came under a week before World Happiness Day.

D. What the UN declared was beneficial to all human beings.

4.What is the best title of the passage?

A. World Happiness Day. B. Happiness — forever pursuit.

C. What's your happiness index(指数)? D. The 2018 World Happiness Report.

Screen time increases by 300 percent between the ages of 1 and 3 according to a recent study. In a perfect world, parents would always choose outdoor time over screen time. But for many parents, decreasing screen time isn't as simple as it sounds. That's because screens are increasingly used as an entertainment and distraction（分心）tool for kids which parents think is necessary due to a lack of quality childcare.

The United States government defines affordable childcare as care costing no more than 7 percent of a family's total income, yet more than 40 percent of families say they set aside more than 15 percent of their total income for it, according to a 2019 survey published by Care. com.

Affordable childcare in America is a dream. “Screen time is used as a last substitute for childcare for many families,” says licensed child therapist（治疗师）Katie Lear. “Particularly for parents who work from home, it can be hard to justify hiring a caregiver or paying for daycare. And yet children need to be able to keep themselves occupied during important work calls. Turning on the TV can buy the parent some valuable time during what can be a very tiring day."

If affordable childcare wasn't just a daydream, if the system we have wasn't dependent on two incomes, if parents could actually afford not to work 50+ hours a week, if childcare centers could afford to pay their workers a desirable wage, then maybe, we'd see screen time decrease instead of increase. We know our kids should be interacting with something other than You Tube videos and flash games for hours a week. But before we fix our broken system and before affordable, quality childcare becomes a reality, parents and caregivers are going to do whatever they can to make it, and that includes using screens as passive childcare.

1.Why do parents allow their children to spend much time on screens?

A.To please their children.

B.To make up the lack of quality childcare.

C.To attract kids' attention to classes online.

D.To help children learn about necessary technology.

2.What do the statistics in Paragraph 2 indicate?

A.Childcare workers have high income.

B.Childcare centers are popular in America.

C.Childcare is a heavy burden for parents.

D.Childcare is supported by local government.

3.Why is Lear mentioned in the text?

A.To uncover the reason for screen time as childcare.

B.To prove the advantages of adopting c-products.

C.To present the ways of parents' improving childcare.

D.To explain the benefits of hiring a caregiver.

4.What's the key in reducing children's screen time?

A.Enough company time. B.High income in the family.

C.Turning off the TV. D.Hiring a caregiver.

Experts say farmers will need to produce about 70 percent more food by the middle of the century. They predict that 9 billion people will need to be fed worldwide by 2050. The prediction means experts will need to develop more effective farming methods that cause less harm to the environment to produce more food. Experts say living things called bacteria could help achieve that goal. A bacterium is an organism.It is so small that it can be seen only with a microscope.

Researchers are finding extremely small organisms in the ground. One gram of soil contains between 100 million and one billion bacteria. Bacteria are taking part in a healthy ex- change with the plants that share the soil. Around plant roots, bacteria change chemicals in the air and soil into food for the plants. The bacteria include the material known as fungi(真菌). Some bacteria act as bodyguards. They produce anti-bodies and other chemicals to fight harmful bacteria.

Plants make sugar through a process called photosynthesis (光合作用).This happens when a plant receiving light changes water and carbon dioxide into food. Much of the sugar is pumped down through the roots. There, it is turned into sugar-based food and released into the soil. That is done to get bacteria to help the plants grow better. Some of the organisms turn chemicals in the air and soil into food that the plants can eat.

The biosciences company Novozymes already sells one kind of fungi. It has found a way to produce it in very large quantities and offer it to farmers as.a bio-pesticide (生物农药).A bio-pesticide protects crops from animals and bacteria. If so, farmers can harvest more crops.

1.What do the experts’ statistics in paragraph 1 show?

A.Bacteria have a good effect on farming.

B.There will be more harmful bacteria in 2050.

C.There's no need to worry about the problem of future food.

D.More food will be needed to feed more people in the future.

2.What's the connection between plants and bacteria according to paragraph 3?

A.Bacteria can't live without plants. B.Plants get benefit from bacteria .

C.They make sugar cooperatively. D.They compete for more sunshine.

3.What does Novozymes do?

A.It sells crops and animals.

B.It beautifies the environment.

C.It provides farmers with materials free of charge.

D.It produces fungi as a bio-pesticide.

4.What is the best title for the text?

A.Crops of High Quality Need Developing

B.Bacteria May Help Meet Food Needs of the Future

C.A Large Quantity of Farmland Should Be Improved

D.Diseases and Pests Can Be Controlled in the Future

The United Nations is warning that the world is not prepared to deal with the fast growth of cities. The World Economic and Social Survey 2013 calls for new ways to meet the needs of city populations. More than 6.5 billion people are expected to be living in cities by 2050.

Most new city dwellers will be in developing countries. The United Nations says the effect on limited resources in many countries will be huge. The World Economic and Social Survey points to the increasing demand for energy, water, sanitation, public services, education and health care.

The world population is expected to rise to more than nine billion by 2050, two-thirds of all people are expected to live in cities. The United Nations says about 80 percent of this growing urban population will be found in Africa and Asia.

The report says sustainable development of urban areas requires coordination and investments to deal with important issues, these include land-use, food security, job creation and transportation.

Willem Van Der Geest is with the United Nations Department of Economic and Social Affairs, he says cities need to work closely with rural communities, so that food supplies can be secured, and the environment can be protected.

"We need enough integration(整合，融合) with cities... An integration between the rural and urban economies is absolutely vital for issues of nutrition, food security, and environmental sustainability."

The report says development in a sustainable（可持续发展）way is important to end poverty. The report also examines the problem of food insecurity, which affects hundreds of millions of people around the world. One in eight people still severely lack nutrition.

UN officials say some things are clear. The Assistant Secretary-General for Economic Development, Shamshad Akhtar, says world food production will have to increase by 70%, that increase will be needed to feed the additional 2.3 billion people expected on the planet by the middle of the century. She says an important part of meeting that need is to waste less food. "There has to be efforts to reduce food wastage. ."

Food and nutrition security are core elements of the sustainable development agenda.

1.The survey includes the following statements except that ______.

A. varieties of demands are hard to meet because of the increasing population in Africa and Asia.

B. one way to put an end to poverty is to be able to develop for a long time.
