Since the beginning of the year, smog(雾霾) has covered parts of North China. In January, Beijing saw only five days without smog. The rising PM2.5 readings terrified many people, and some health experts said that whenever the smog gets serious, hospitals receive more patients suffering acute respiratory (呼吸系统) and heart diseases.
Later, news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe.
So the need to emphasize environmental protection while developing the economy is heard everywhere.
Smog is especially a common concern. As a popular online post said, air may be the only thing that is equal for everyone, despite your income or profession. People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices, but they breathe the same air as everyone else.
At a meeting on Monday, many representatives have expressed their concerns about the air quality, too. One talked about his experience in Beijing. “After taking a taxi from the capital airport to my hotel, which took about an hour, I washed my nose and found the inside of my nose was black. We should ask ourselves this question: Why do we want to develop? It's for living a better life. Dirty air is definitely not a better life，” he said.
China needs to develop its economy and invest (投资) in hightech. Every Chinese has a dream to make China stronger. But without blue sky, clean water and safe food, the achievements in the economy will become meaningless. Space technologies are not to be developed for building a base on Mars so that one day all human beings can move to the red planet because they have destroyed Earth.
What the public wants is a strong and beautiful China. The great efforts must be made to promote ecological progress and build a beautiful China. The words have shown the central government's determination to address the environment issue.The effect of smog doesn't include ________.
| A．the increase of people's income |

| D．Because nobody can avoid it. |
To make China stronger we have to develop economy, but ________.
| A．we have to sacrifice air as the price |
| B．the smog is the only by product |
| C．ecological progress can be ignored |
| D．the dirty air is not what we want |

Traditional businessmen feel worried that growing ecommerce will reduce their share of the market.
According to a survey, 90% of some people's purchases are made on the computer. As they find that by being able to go online and choose the things that they need to choose, and have them delivered right to their doorsteps, they could no longer be bothered with driving, the crowds, the noise of that, and they usually get a better selection.
Cornell University Marketing Professor, MeLaughlin says traditional stores can keep their customers by offering goods like clothing, which customers may want to see and try on before purchasing, as well as items that are difficult to ship. He says some traditional stores are also pleasing customers with services that set up or repair computers and electronics.
Traditional stores also offer a social experience that some shoppers enjoy. There is still a lot of emotion in the buying decision that takes place. Oftentimes, you need that last sense of “this is exactly what I want” before you part with money. And you can't always get that online. It's a rather cold process.
As more and more people have Internet access and smart phones, online commerce is likely to continue its growth here in the United States and in other countries.Traditional businessmen feel upset because ________.
| A．consumers can get a better selection by shopping online |
| B．growing online sales will cut their share of the market |
| C．people like to have their goods delivered to their house |
| D．more and more people purchase things on the computer |
According to McLaughlin, some traditional stores are keeping customers by ________.
| A．delivering goods to each doorstep |
| B．inviting customers to try on clothing |
| C．providing customers with extra services |
| D．repairing computers and electronics only |
From the 4th paragraph, we know that ________.
| A．some shoppers like the social climate in traditional stores |
| B．the process of shopping online is full of emotion |
| C．online shoppers tend to be cold to each other |
| D．making buying decisions in traditional shops is difficult |
“Plants were expected to get larger with increased carbon dioxide in atmosphere, but changes in temperature, humidity(湿度) and nutrient availability（养分有效性） seem to trumped the benefits of increased carbon dioxide，” said researchers from the National University of Singapore.
45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking(缩小的) creatures.
“We do not yet know the mechanisms（原理） involved, or why some organism are getting smaller while others are unaffected，” the researchers said. “Until we understand more, we could be risking negative consequences that we can't yet quantify.”
The change was big in coldblooded animals. Only two decades of warmer temperatures were enough to make reptiles（爬行动物） smaller. An increase of 1 degree centigrade caused nearly a 10 percent increase in metabolism (新陈代谢). Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growth. There is a recent report on warmer temperatures' negative effects on plankton（浮游生物）, the base of the marine（海洋的） ecosystem.
Warmblooded animals weren't immune（免于） from the size change caused by climate change. Many birds are now smaller. Mammals have been miniaturized too. Soay sheep are thinner. Red deer are weaker. And polar bears are smaller, compared with historical records.
This is not the first time this has happened in Earth's history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a long time than the current climate change.
The speed of modern climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times. So, it is likely that more negative influences of climate change will be shown in future.Which of the following would be the best title for the passage? ________
| A．Why do some species become smaller? |
| B．Species become smaller as climate warms |
| C．Climate change has many negative effects |
| D．How does temperature change in Earth's history? |
The underlined word “trumped” in the first paragraph can be replaced by ________.
| A．been neglected by | B．been less than |
| C．been weakened by | D．had strong influences than |
Researchers from the National University of Singapore believe that ________.
| A．too many studies on animals' size have been done |
| B．all the animals on the earth have become smaller |
| C．how climate change effects animals' size has not been found clearly |
| D．people can avoid the negative effects of climate change |
What can we learn from the passage? ________
| A．Ants, bees and spiders have been shrinking by 50% to 70% in the past decade. |
| B．Birds have suffered more from climate change than fish. |
| C．Climate change has even affected plankton negatively. |
| D．A warming event causing species to become smaller has never happened before. |
I was driving home the other day on a sunny afternoon. I had a smile on my face as I sang along to the songs on the radio. It was such a beautiful day that I felt full of happiness. My good mood ended, however, when the radio station took a news break between songs. Then suddenly I found myself listening to yet another story of a rich famous man who had broken the law. I shook my head as I came to a red traffic light.
As I pulled to a stop I noticed four leatherjacketed bikers. They were standing in the middle of the road with two on either side of the light. They looked rough and dangerous, but as I got closer I noticed each one was holding their helmet in their hands. I rolled down my window as one approached my car. “We are the Brother of the Wheel，” he said. “We are collecting money for Christmas Toy Drive for needy children.” As I pulled a dollar out of my wallet I looked past his beard and into his eyes. They shined with goodness and kindness that came right from his soul. I dropped the money in his helmet and waved to the other bikers as I drove off. My good mood had returned. My faith in mankind had been bolstered. And I remembered once again never to judge people by their appearance.
Our society often judges books by their covers but God reads what is written in our hearts and souls. Perhaps one day we will all learn to see the world through the same eyes. Perhaps one day we will realize that looks matter little and actions matter much.The writer's good mood ended when ________.

Eco City Farms are becoming more popular in cities and towns around the United States.
Eco City Farms in Edmonston,Maryland, is located near shopping centers, car repair shops and homes. The neighborhood is a workingclass community. People do not have very much money, and they have limited access to fresh food in markets.

Her son Alston Clark thinks his experience is very valuable. “I like coming out here，” he says, “You know, you connect with the earth, where your food comes from. You appreciate the food a little bit more.”
Margaret Morgan started Eco City Farms. She thinks of it as a place where people can learn to live healthier lives. “Growing food in a community brings people together，” she continues, “Every piece of what we do here is a demonstration to show people everything about how to have an ecofriendly community.” she says. From the Eco City Farms people come to know that they are not only growing food and raising chickens and bees, but improving the soil with compost (肥料) made from food waste.
Eco City Farms is an experimental operation. The farm gets its power not from the local electricity networks, but from the sun with solar panels. In winter, the green houses use a geothermal (地热) system.
