"Why should I care about the environment?" some people ask. There is a very simple reason: We live on the earth, and it is the only place we can live on right now, as we cannot live in space yet. If we treat the earth like a garbage dump, it will become dirty and unlivable. If we treat it well by being eco-conscious, the earth will stay clean and suitable for living, for ourselves and for our children. What is "being eco-conscious"? Being eco-conscious means being aware of your actions, and what you do to the environment. For example, you might think, "Using hairspray is great for fixing my hair." However, if you are eco-conscious, you would ask, "Does this hairspray have CFCs in it? Could I be destroying the earth by using hairspray?" How can I be eco-conscious? You can find many simple ways to help the environment in your everyday life. When you go shopping, bring a bag or a basket with you. Please try not to use plastic bags as much as you can. You can go to work by bike or on foot if it is not far from your home. You can put your rubbish into different bags, which makes it convenient for recycling. You can eat less chewing gum. You can use your own chopsticks instead of the disposable ones in your company or in restaurants. You can put batteries in a special box instead of in garbage bins. You can use the water which has been used for washing vegetables or fruits to clean the floor and the toilet or to water your garden. You can turn off the decorative lights in your room when watching TV. You can turn down your air conditioner by one degree, as this will cause a 10% reduction in energy use. You can use recycled paper. Every ton of recycled office paper saves 380 gallons of oil. You can also use recycled glass instead of glass made from raw materials. This will reduce the related air pollution by 20%, and the related water pollution by 50%. Please believe that. If you do a little, it will make a big difference. According to the author, which of the following statements is WRONG? A) Being eco-conscious means you should know much about the environment. B) The more we care, the better the environment will be. C) If each of us just does a little, we can't make any difference. D) If we treat the earth badly, we'll make a lot of trouble for ourselves.

On July 1 at exactly 7:59:59, Bejing time, the world' s atomic clocks will pause for a single second, or, more precisely, change to the unusual time of 7:59:60. The addition of a leap second , is to keep our clocks in time with the slowing of Earth' s rotation and astronomical time as measured by the sun. Just one extra second could affect the way computers and websites work, however. When the last leap second was added back in 2012, the community website Reddit crashed. For Reddit, the problem was that a Linux system got confused when it checked the network time and found an extra second. Speaking to Wired about the problem back in 2012, Linux creator Linus Torvalds commented:"Almost every time we have a leap second, we find something. It' s really annoying, because it' s code that is almost never used, and thus not tested by users under their normal conditions. " Companies have thought of their own solutions, and Google' s"leap smear"may be the best- known example. As company engineer Christopher Pascoe explains in a blog post, companies usually try to turn back the clocks by one second at the end of the day so that they play that second again. However, Pascoe believes this creates problems. He asked:"Does email that comes in during that second get stored correctly?"Google has a solution: Cut the extra second into milliseconds and then put these tiny amounts of time into the system throughout the day."This means that when it became time to add an extra second at midnight."Says Pascoe."Our clocks have already taken this into account over the course of the day." For many companies without Google' s money, however, the leap second will likely still cause some crashes. What happened to the website Reddit when the leap second was added in 2012? A) It crashed because of a virus attack. B) Its network time added two extra seconds. C) All of the code in its Linux system went wrong. D) One of its software systems got confused and the site broke down.

Q: Newspapers are not nearly as popular today as they were in the past. There are not very many people who seriously read a newspaper every day. Most people read only the sports pages, the advice or the gossip columns, the comics, and perhaps the classified advertisements. Most people don't take the time to read the real news. They attempt to catch the reader's interest with pictures and exciting headlines. These techniques are used on the front page because it is the first thing you see when you pick up the paper. The first page attracts attention and encourages the reader to look through the rest of the paper. This is why editors always look for a good first page story and headline to make them stop and look. If the headline is horrible enough or frightening enough or wild enough, perhaps they will go on to read the front page anymore. They may read the headlines, but that is all, then they turn to the sports page, or comics, or advertisements. It seems that people do not want the news from a newspaper anymore. They say they get the news on the television now. More people watch television news because it is easier and more interesting than reading a newspaper. What about you? Do you read news from a newspaper? Do you think it is easier to get the news from television? Or do you care about news at all? Would you mind if there were no news? According to the passage, most people read all of the following except _ . A) the sports page B) comics C) advertisements D) the real news

A group of professional people put this question to a group of 4 to 8 year-olds, "What does love mean?" The answers they got were broader and deeper than anyone could have imagined: "When my grandmother got arthritis , she couldn't bend over and paint her toenails any more. So my grandfather does it for her all the time, even when his hands got arthritis too. That's love." Rebecca-----age 8 "Love is when you go out to eat and give somebody most of your French fries without making them give you any of theirs." Chrissy-----age 6 "Love is when my mommy makes coffee for my daddy and she takes a sip before giving it to him, to make sure the taste is OK." Danny----age 7 "Love is when you tell a guy you like his shirt, and then he wears it every day." Noelle----age 7 "My mommy loves me more than anybody. You don't see anyone else kissing me to sleep at night." Clare---- age 6 "Love is when my mommy sees Daddy smelly and sweaty and still says he is handsomer than Robert Redford." Chris----age 7 Author and lecturer Leo Buscaglia once talked about a contest he was asked to judge. The purpose of the contest was to find the most caring child. The winner was a four-year-old child whose next door neighbor was an elderly gentleman who had recently lost his wife. Upon seeing the man cry, the little boy went into the old gentleman's yard, climbed onto his lap, and just sat there. When his mother asked him what he had said to the neighbor, the little boy said, "Nothing. I just helped him cry." The children's answers are mainly based on _ . A) their own stories B) their family stories C) what happened around them D) how they viewed people around them
