We take it for granted that with memory we can remember most of things which happened in our life. But it is difficult to imagine what life would be like without memory. The meanings of thousands of everyday perceptions(感知), the basis for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.
Memory can be defined as the ability to keep information available for later use. It not only includes “remembering” things like arithmetic(算术) or historical facts, but also involves any change in the way an animal typically behaves. Memory is involved when a rat gives up eating grain because he has sniffed something suspicious in the grain pile.
Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory storage capacity(容量) of a computer with that of a human being. The instant access memory of a large computer may hold up to 100,000 “words”—strings of alphabetic or numerical characters—ready for instant use. An average U.S. teenager probably recognizes the meaning of about 1000,000 words of English. However, this is but a part of the total amount of information that the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognize on sight.
The use of words is the basis of the advanced problem solving intelligence of human beings. A large part of a person’s memory is in terms of words and combinations of words. But while language greatly expands the number and the kind of things a person can remember, it also requires a huge memory capacity. It may well be this capacity that distinguishes humans, setting them apart from other animals.Which of the following is true about memory?

| B．It is based on the decisions we made in the past. |
| C．It is rooted in our past habits and skills. |
| D．It connects our past experiences with the present. |

It seems like every day there's some new research about whether our favorite drinks are good for us. One day, science says a glass of red wine a day will help us live longer. The next day, maybe not. It seems journalists are pretty interested in wine research and the same might be said for coffee. Now there's been a lot of research into whether coffee's good for our health "the results have really been mixed"，admits Neal Freedman who led the coffee study and published his findings in a medical journal recently. "There's been some evidence that coffee might increase the risk of certain diseases and there's also been maybe more recent evidence that coffee may protect against other diseases as well".
Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health. They analyzed data collected from more than 400，000 Americans ages 50 to 70 participating in the study. "We found that the coffee drinkers had a modestly lower risk of death than the non-drinkers， he said. Here's what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study when the researchers looked at specific causes of death, coffee drinking appeared to cut the risk of dying from heart disease, lung disease injuries, accidents and infections.
Now, Freedman stressed that the study doesn't prove coffee can make people live longer .A study like this can never prove a cause-and-effect relationship. All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffee is really good for you, scientists have no idea why.According to the first paragraph，reporters would like to know the research findings of_______.

Writer and teacher Yin Jianli's stories and thoughts about bringing up her daughter
Yuanyuan have been a constant source of inspiration for parents over the past 16 years.
Her book, A Good Mother Exceeds Good Teachers, published by Writers Publishing House, has been a bestseller on Dangdang and Amazon's online platforms

Ray Travers sat back at the large desk, and looked around his plush（豪华的）office. He was tired
Ray's eyes stopped at a painting on the wall. It was a gift given by an old friend，Bull，as a farewell gift when he left his hometown He recalled the life spent in that small town; pleasant times. The many hours he spent talking to his good friend, and the tales he was told about hunting in the Africa of old.
Memories flowed back more than ten years; he remembered how he enjoyed hearing about the wonderful hunting，and how he wished he could have shared those times.
Ray opened his desk drawer and brought out a wooden box. He opened the lid and exposed a work of art，a hand-made hunting knife. This was a gift from Bull，given to Ray more than 20 years ago. It was one of the first knives Bull had made, and Ray had called it "Zambezi"，the river where Bull had been so many times.
He closed the box and sat upright at his desk；he was driving himself hard, and deserved a break. Things were going well with the business，everything running smoothly. He could afford a week off！
He went back home. A week in the hometown would be like going back in history. "Man, it's going to be good,”Ray said aloud，as he turned onto the highway and watched the city lights fast disappearing，as he looked in the rearview mirror. The powerful car going its way through the night, headlights piercing（穿透）the darkness. Memories danced through the man's mind. Memories of good times，when he knew what it was to relax, to talk，and to really visit.

However urban life strikes you, cities worldwide have been growing ever more rapidly. Some of this growth has occurred in the developed world, but the most dramatic increase has been in the Third World. Almost all the world’s population growth over the next 30 years will take place in the cities of developing countries.
By the year 2030, for the first time in history, 60 percent of the world’s people will be living in cities.
This is actually good news in some ways. “Cities are the fundamental building blocks of prosperity（繁荣）,” says Marc Weiss, chairman of the Prague Institute for Global Urban Development, “both for the nation and for families.” Industrial and commercial activities in urban areas account for between 50 and 80 percent of the gross domestic product (GDP) in most countries of the world “there’s the crazy notion that the way to deal with a city’s problems is to keep people out of them,” Weiss continued. “But the problems of the rural life are even more serious than those of the city.” For better or worse, urban-watchers are clear on one point: The quality of life for most people in the future will be determined by the quality of cities. Those cities will be bigger than ever. And yet, population numbers by themselves don’t determine a city’s prospects; after all, Addis Ababa, Ethiopia, and Hamburg, Germany, have the same population. Nor is explosive growth necessarily the determining factor. “City problems,” one authority points out, “mostly have to do with weak, ineffective, and usually unrepresentative city governments.”According to the passage, in the year of 2030 _______.
| A．rural area will be extinct |
| B．most people will live in cities |
| C．there will be 21 cities having a population of more than 10 million |
| D．the third world will keep abreast with the developed world |
In the author’s opinion, _________.
| A．better city, better life |
| B．both urban and rural areas have a larger population |
| C．the larger population, the faster a city develops |
| D．both urban and rural areas have larger gross domestic products |
Which statement is NOT true according to the passage?
| A．Cities contribute more to the GDP than the villagers. |
| B．Some problems are more easily solved in cities than in country. |
| C．The developing countries develop faster than the developed countries. |
| D．It’s impossible to solve urban problems by getting people out of cities. |
The last paragraph implies that ____________.
| A．Public services are ineffective |
| B．Cities are increasing too fast |
| C．Population is not linked with development |
| D．Government should be responsible for the problems in the cities |
