Many of the world’s pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further pollution by industry. If the rapid increase of world population in countries continues at the present rate, there may be much greater harm to human beings. Some scientists speak of the increase in numbers of people as “population pollution.”
About 2,000 years ago, the world population was probably about 250 million. It reached a billion in 1850. By 1930 the population was two billion. It is now three and a half billion. It is expected to double by the year 2,000. If the population continues to grow at the same rate, there will be 25 billion in the world a hundred years from now.
Man has been using the earth’s resources more and more rapidly over the past years. Some of them are almost used up. Now many people believe that man’s greatest problem is how to control the growth of the population. The material supplies in the world will be far from enough to support the human population, in time to come, if the present rate of increase continues. Already there is overcrowding in many cities and starvation in some countries. Should man’s population keep on growing so rapidly as before? Many people believe that human survival in the future depends on the answer to this question.
59. The rapid increase in population is considered to be __________.
A. the increase of resources B. population pollution
C. the development of mankind D. the present rate
60. The world population will be _________ by the year 2,000.
A. 7 billion B. 250 million C. 25 billion D. 3.5 billion
61. If the present rate of increase continue, ________________.
A. the world is going to end
B. the earth won’t be able to support the growing population in the future
C. pollution has nothing to do with the rapidly increasing population
D. there would be four billion in the world a hundred years from now
62. Which of the following is WRONG according to the passage?
A. In 1850 the world population reached a billion.
B. Man must fight a battle against population pollution.
C. The world’s population is increasing with years.
D. All of the earth’s resources are gone now.

Here’s a new warning from health experts: sitting is deadly. Scientists are increasingly warning that sitting for long periods, even if you exercise regularly, could be bad for your health. And it doesn't matter where the sitting takes place--in the office, at school, in the car or before a computer or TV. Just the overall number of hours it takes matters. Several studies suggest people who spend most of their days sitting are more likely to be fat, have a heart attack or even die. While health officials have issued(发布) guidelines advising on the least amounts of physical activities, they haven’t suggested people try to limit how much time they spend in a seated position.
“After four hours of sitting, the body starts to send harmful signals,” said Ekblom-Bak of the Swedish School of Sport and Health Sciences. She explained that genes controlling the amount of glucose(葡萄糖) and fat in the body start to shut down.
Even for people who exercise, spending long periods of time sitting at a desk is still harmful. Tim Armstrong, a physical activity expert at the World Health Organization, said people who exercise every day but still spend a lot of time sitting might get more benefits if that exercise were spread across the day, rather than in a single hour.
Still in a study that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat more had a higher death risk, whether they exercised or not. Experts said more research is needed to figure out just how much sitting is dangerous, and what might be possible to offset those effects.
People should keep exercising because that has a lot of benefits,” Ekblom-Bak said. “And when they’re in the office, they should try to interrupt sitting as often as possible.”
1.The underlined word “offset" in Paragraph 6 most probably means_______.
A. get rid of B. make use of
C. work out D. turn to
2.Sitting too much is dangerous because it can________ .
A. increase glucose and fat in the body
B. make a person become lazy
C. destroy the balance of glucose and fat in the body
D. make a person unable to exercise enough in a day
3.In the opinion of Ekblom-Bak, when at work, you’d better have a rest by_______ .
A. taking a walk around your office
B. chatting online or playing computer games
C. sending your friends emails
D. listening to music while sitting
4.Which of the following might be the best title for the passage?
A. More and More People Sit Too Much
B. Side Effects of Sitting Too Much
C. Don’t Sit Too Much While Working
D. Sitting Too Much Could Be Dangerous

“Smombies” are very real and a growing cause for concern. Tired of having to constantly warn both locals and tourists to pay more attention to their surroundings to avoid serious accidents, authorities of a small German town have come up with a more positive solution — embedding (嵌入) traffic lights in the pavement to make them visible to people constantly looking down at their phones while walking.
The seemingly ridiculous safety measure was put in place. Authorities in Augsburg decided to act, installing ground level traffic lights at two tram (有轨电车) stops last Tuesday. The lights flash red every time a tram is approaching, or when the regular traffic light turns red. “We realized that the normal traffic light isn’t in the line of sight of many pedestrians these days,” said Tobias Hermes, a city administration official. “So we decided to have an additional set of lights — the more we have, the more people are likely to notice them.”
Some Augsburg residents appear to be quite happy with the idea. “I think it makes sense,” said Jack Smith, “One always sees young people these days running over red lights. This makes it more obvious that you need to stop.” Others, however, found the need for ground traffic lights disturbing and even frightening. “I find it scary that smart phone users are so engrossed that they need to install lights in the ground so that they notice the tram coming,” one person told the local paper.
But do this kind of pavement-embedded lights actually work? Well, if one interviewed teenager is to be believed, not really, “To be honest I didn’t even notice it,” he said, “Maybe it’d be useful at night, but yeah, I didn’t realize it was there until just now.”
The word “smombie” — a mashup of the words smart phone and zombie — was born in Germany. It was voted “youth word of the year” in 2017, but the serious consequences of this behaviour are no laughing matter.
1.What can be inferred about “smombies”?
A. They are fond of walking.
B. They concern others very much.
C. They look at phones while walking.
D. They hate locals and tourists.
2.Which of the following can replace the underlined word “engrossed” in Paragraph 4?
A. Disturbed. B. Frightened.
C. Encouraged. D. Addicted.
3.What is the author’s attitude to “smombies”?
A. Positive. B. Negative.
C. Indifferent. D. Interested.
4.What is the text mainly about?
A. Ground traffic lights for people looking at smart phones.
B. Effective ways to educate people to obey traffic rules.
C. The meanings of ground traffic lights.
D. The serious problem of traffic safety.

With big handbags becoming a key fashion accessory(配饰) for working women, health experts are warning they can also become a key health concern.
Bags for women have become bigger and heavier as designers combine briefcases with handbags and straps have become longer, resulting in many users complaining of neck, shoulder and back problems.
“I see so many women with neck pains and headaches and what I usually do is look for their purse and pick it up,”said Jane Sadler, a family practice physician at Baylor Medical Center in Garland, Texas.“We take it over to the scale and weigh it and usually they’re anywhere from 7 to 10 pounds. We’re really going to see women with more and more problems later on if we continue the big purse craze.”
William Case, a physical therapist(临床医生)in private practice in Houston, Texas, urged designers“to place a cute, educational caution tag(标签) on all bags to inform buyers of potential neck and shoulder dangers.”Above all, he suggested correct posture while carrying big purses, keeping the head and shoulders upright. Patients should also often change the size and weight of purses carried.
“The extra-large purses are quite extraordinary. They look beautiful when the women wear them, but I don’t know how aware they are of the potential problems,”Case said.
Placing objects on one shoulder was one of the least efficient(高效率的) ways of carrying a load, according to a professor from Cornell University in New York State.“This causes a great imbalance,”he said.“If a big bag is a fashion accessory, then occasional and symbolic use is fine. If not, then keep it light.”
1.Jane Salder would“look for their purse and pick it up”in order to see whether the purses .
A．contained enough B．were worth a lot of pounds
C．were too heavy D．were too large
2.Which correctly explains the meaning of the underlined word“posture”in the 4th paragraph?
A．The way you position your body.
B．The part of your body where you place a weight.
C．The strength you use to carry a weight.
D．The height of the weight you carry.
3. None of the experts advised big bag users to .
A．be aware of the big-bag problems
B．wear big bags in the right way
C．avoid using big bags very often
D．give up the fashion to keep fit

The rapid growth of cities worldwide over the next two decades will cause significant risks to people and the global environment, according to analysis.
Researches from Yale and Stanford predict that by 2030 urban areas will expand by 590,000 square miles—nearly the size of Mongolia—to meet the needs of 1.47 billion more people living in urban areas.
“It is likely that these cities are going to be developed in places that are the most biologically diverse,” said Karen Seto, a famous scientist at Yale University. “They are going to be growing and expanding into forests, biological hotspots, savannas(热带稀缺大草原), coastlines—sensitive and vulnerable places.”
Urban areas, they found, have been expanding more rapidly along coasts. “Of all the places for cities to grow, coasts are the most sensitive. People and buildings along the coast are at risk of flooding and other environmental disasters,” said Seto.
The study provides the first estimate of how fast urban areas globally are growing and how fast they may grow in the future. “We know a lot about global patterns of urban population growth, but we know significantly less about how urban areas are changing,” she said. “Changes in land cover associated with urbanization lead to many environmental changes, from habitats loss and agricultural land conversion(转化) to changes in local and regional climate.”
The researchers examined studies that used satellite data to map urban growth and found that from 1970 to 2000 the world’s urban footprint had grown by at least 22,400 square miles—half the size of Ohio.
“This number is numerous, but, in actuality, urban land expansion has been far greater than what our analysis shows because we only looked at the published studies that used satellite data,” said Seto. “We found that 48 of the most populated urban areas have been studied using satellite data, with findings in journals. This means that we’re not tracking the physical expansion of more than half of the world’s largest cities.”
Half of urban land expansion in China is driven by a rising middle class, whereas the size of cities in India and Africa is driven primarily by population growth. “Rising incomes translate into rising demand for bigger homes and more land for urban development, which has a great effect on biodiversity conservations, loss of carbon sinks and energy use.”
1.According to the passage, the most dangerous place for city expansion is the _____.
A．forest B．desert C．savannas D．coastline
2.The underlined word “vulnerable” (in Para. 3) probably means “____”.
A．diverse in plants B．beautiful in scenery
C．easily damaged D．very productive
3.From Para. 5, we can infer that ____.
A．urbanization is a good way to improve people’s standards of living
B．cities develop very fast and more and more people come to live in cities
C．more and more agricultural farmlands are used to make room for local animals
D．in the past, researchers focused their attention on the expanding urban areas
4.Cities in Africa become bigger and bigger mainly because of their ____.
A．growing population B．rising middle class
C．unique living patterns D．economic development
