5 . Under the background of the slow growth of its total population to 1.44 billion, China has seen a sharp rise in older adults over the past decade, solidifying the country’s rapidly aging pattern, the latest national census (人口普查) data shows. The population on the Chinese mainland increased by an average of 0.53 percent annually during the past 10 years to 1.41 billion, compared with an annual growth rate of 0.57 percent from 2000 to 2010, according to the 7th national census published by the National Bureau of Statistics.
“The growth of the total population has slowed down but remains at a steady pace,” Ning Jizhe, head of the bureau, said at a news conference. “Based on trends in recent years, China’s population will grow at an increasingly slow rate in the future while remaining above 1.4 billion.” The increasing elderly population has become a defining feature of the past decade.
Ning said an aging society will set the tone for China's population structure for a long time, presenting challenges and opportunities. “A graying population will pile pressure on supply of labor force and social services, as well as adding to families’ elderly care burden. But more elderly people could also motivate consumption of products and services targeting this age group, and advance the development of some technologies,” he said.
Ning added that those between the ages of 60 and 69, who are equipped with knowledge, experience and skills and are generally in good health, make up nearly 56 percent of all older adults. “Their potential to continue making contributions to society and playing a constructive role is big,” he responded to a question on the outlook for raising the retirement age and carrying out other potential measures aimed at addressing the aging trend. Some population economists also said the latest number and proportion (比例) of elderly are largely within predictions, and the aging trend will continue for a long time.

Many young people believe shared bicycles have many advantages. They are not expensive to rent, they do not have to be protected from thieves, and there is no need to repair them. You just have to change them for another one. They are also environment friendly and lower the use of cars, which also helps to relieve traffic. In fact, it is considered an awesome(可怕的) combination of technology and tradition.
Since they appeared, shared bicycles have raised a lot of dust. There is no doubt about the benefits but the disadvantages cannot be ignored. Many problems related to shared bicycles have appeared. It is not only due to bad behavior from some users who always want to seize the bicycles, but also because of the mess that has been created since one can leave the bicycle anywhere, which is against public urban order management. There are so many poorly parked bikes that sometimes they end up blocking streets.
In Xi Luo yuan, Beijing, the “Civilized Use of Bicycles” campaign (运动)has been launched. In addition to having 40 officially permitted stops, there are also clear signals(信号) to lead users to these stops. A team of supervisors keep order in the area. This is the first area that is part of an official system to manage bicycles. The purpose of this campaign is to solve the mess that the popularity of shared bicycles is causing in Beijing, both with the participation of companies and the users. If the pilot plan works out well in Xi Luo yuan, it will be extended to all of the cities in China.

7 . Many of us enjoy doing it: you turn on the camera on your mobile phone and hold it at a high angle, making your eyes look bigger and your cheekbones more defined. You turn to your best side and click. There it is-your selfie.
Over the past several years , the “selfie” has become a well-known term across the globe. The Oxford English Dictionary added the word to their online dictionary and defined it as: “A photograph that one has taken of oneself, typically one taken with a smartphone or webcam and uploaded to a social media website.”
Today it’s not difficult to find social web pages full of photos that people have taken of themselves and their friends. And selfie culture has become especially relevant to young people. As many as 91 percent of teenagers have posted photos of themselves online, according to a recent survey by the US Pew Research Center.
So what are the reasons for the rise of selfie culture?
“Ordinary people shows the cult(狂热)of the selfie,” Pamela Rutledge, a professor from the Massachusetts School of Professional Psychology, told Vogue magazine. “There are more photographs available now of ordinary people than models.”
Posting selfies also allows you to control your image online. “I like having the power to choose how I look, even if I’m making a funny face,” Samantha Barks, 19, a high school student in the US, told Vogue.
In addition to self-expression and documentation, selfies “allow of a close friendship for long-distance friends, because you can see each other’s faces every day”, wrote Casey Miller at The Huffington Post.
But Jill Weber, a US psychologist, is concerned that selfies might lead to social problems. “There’s a danger that your self-esteem may start to be tied to the comments and ‘likes’ you get when you post a selfie, and those comments and likes aren’t based on who you are-but based on what you look like,” Weber told Vogue. “When you get nothing or a negative response, your confidence can plummet.”

9 . Most of the people who appear most often and most gloriously in the history books are great conquerors and generals, while the people who really helped civilization forward are often never mentioned. We do not know who first set a broken leg, or launched a seaworthy boat, or calculated the length of the year, but we know all about the killers and destroyers. People think so much of them that on all the highest pillars in the great cities of the world you will find the figure of a conqueror or a general.
It is possible they are, but they are not the most civilized. Animals fight, so do savages; so to be good at fighting is to be good in the way in which an animal or a savage is good, but it is not to be civilized.
This is what the story of mankind has on the whole been like. But we must not expect too much. After all, the race of men has only just started. From the point of view of evolution, human beings are very young indeed, babies of a few months old. Scientists assume that there has been life of some sort on the earth for about twelve hundred million years; but there have been men for only one million years, and there has been civilized men for about eight thousand years.
A.Even being good at getting others to fight most efficiently is not being civilized. |
B.Most people believe those who have conquered the most nations are the greatest. |
C.However, every year conflicts between countries and nations still claim thousands of lives. |
D.And not only has it won, buts also because it has won, it has been in the right. |
E.So there has been little time to learn in, but there will be oceans of time in which to learn better. |
F.People don’t fight and kill each other in the streets, but nations still behave like savages. |
10 . If someone were to ask me what it is like to be a student in today’s society, I would probably answer them something like this: Being a student in today’s society is not always easy.
Adults often tell us that we don’t know what stress (压力) is. But we as teenage students have our own levels of stress. For example, all school activities require you to uphold your grade point to high standards.
Then, getting your homework turned in on time seems simple, but you still hope to have a life outside of school as well. Many students in their high school years start their first job, so now you have school in the mornings and then you’re off to part-time work. By the time you are done there, you are too tired to finish your school work, but you stay up late to try and return to school feeling sleepy the next day. What good is that?
Let’s not forget about peer (同龄人) pressure. All high school students meet with it at some point in their lives. High school can be a place where students are made fun of and pointed at.
My point is, it is more stressful to be a student in high school than adults believe. Our “stress” may not include paying bills or taking care of a family, but I’m sure if the adults in our lives could go back to school today, they would be surprised at how much it has changed.
I know that the world outside of school is often hard and that the responsibilities are serious. That’s exactly why I know that the focus I give to my future is important in leading me to a career (事业) that will allow me to contribute (贡献) to society.
