The nervous-looking young man had waited for a few moments—outside the jeweler's before he got enough courage to enter. He was warmly greeted by a young assistant. James felt a rush of blood to his face as he explained he would be bringing in his future wife to choose a birthday present. The assistant listened carefully and told him he'd better buy a necklace. He wasn't used to buying jewellery and was a little worried about over-spending. After some discussion as to a reasonable price and the type, the assistant showed him dozens of necklaces and helped him to choose. At last James chose one and left the shop promising to return at five o'clock. When, half an hour later than planned, James did return to the shop with his future wife, Laura, the assistant acted as if she had never seen him before. When she was asked to show them some necklaces, she first brought out some inexpensive ones for them to choose, and then gave them the one she had prepared. A choice was soon made and they went away satisfied. James would certainly come back to buy what he wanted.

    The St. Louis Post-Dispatch reported that the St. Louis Outlet Mall is expanding its restrictions on unaccompanied teenagers. In 2006, a parental-escort (陪同)policy was established: on Fridays and Saturdays starting at 6 p.m., anyone under 17 that isn't accompanied by a guardian who is at least 21 years old will be kicked out of the mall. It was around this time that other malls around the U.S. likewise banned unaccompanied teens during certain evening hours.

Starting from this Friday, the St. Louis Outlet Mall is pushing its parental-escort rule back to 3 p.m. on Fridays and Saturdays. Similarly, the Mall of America expanded its parental-escort policy during the recent holiday shopping season. Normally, the policy bans kids under 16 without guardians(监护人) from 4 p.m. until closing time just on Fridays and Saturdays. But because of a fight in the mall involving dozens of young people that took place on Dec. 18, 2012—- a weekday, the policy was broadened to include peak 2013 holiday shopping hours, including Thanksgiving Day and all of the Christmas week.

    Teen disturbances in other malls may cause more shopping centers to introduce or expand parental-escort policies. The Indianapolis Star noted that two incidents in 2013 in area shopping centers raised the possibility that Indianapolis malls might need to consider banning unaccompanied teenagers.

   Obviously, such bans are aimed at stopping violence and other outbursts involving teenagers. More importantly, from a purely business perspective, these bans aim to attract shoppers who might otherwise be hesitant to go to the mall because of concerns about violence and outbursts involving teenagers. The restrictions allow mall security officers to systematically kick out a group of people that are considered to be loud, thuggish and bad for business overall. But they attract much criticism from online communities. Some argue that teens have the right to shop without a guardian. “Not all teens are disrespectful and troublemakers,” Pamela Chapman wrote. “In fact, it's been my experience that most are good kids.”

Again, the biggest influence on stricter mall policies for teens seems to be that they're just plain good for business. Malls reported strong sales growth after they first carried out the policies six years ago. “We've had some success with the parental-escort policy, and families like shopping out here together,” the manager of the St. Louis Outlet Mall told the St. Louis Post-Dispatch . If there's one rule in retail, it's this—- if a small initiative proves successful in boosting sales, then it's all but guaranteed that a larger initiative will follow.

    One of the most important ways to learn and master the English language is to read, read, and read. It is said that a good reader is also a good writer and a good speaker. However, in today's world, reading is something that most children dislike doing.

    There are simply so many distractions (分心的事物) that books, magazines, and newspapers are often ignored and they are in favor of video games and movies. And while video games and movies also play a role in helping the child learn the English language, they still can't quite compare to reading.

    And as a result, kids are learning less and less. Take a look at an elementary level text book. You'll notice that the books for elementary students are filled with pictures and colors. Those pictures and colors in the elementary level text books aren't there just for the sake (缘由) of design. Colors and pictures make us more engaged in the act of learning grammar. They catch our attention and help us retain (保留) more of what we read. This is especially true for little children who enjoy fun English.

    Children are quite easily distracted. When you ask them to sit down and read quietly, their minds will often wander and it won't take long before you find them doodling (涂鸦) and not doing what you told them to do. But if a book is colourful enough to catch a kid's attention, then you'll have a better chance at getting the kid to sit down long enough to learn English.

    The same principle holds true for interactivity (互动). Like colors and pictures, interactive reading materials like English songs for kids also get the child engaged in what he or she is learning. Interactive reading materials get the child to focus since using them is almost like playing.

    I never planned to be a teacher. I was headed for a law school, for a real career. Teaching was something to "get out of my system". I would teach a couple of years and then go to get a real job. After the first couple of years, I promised myself I would leave if I didn't love my job any more. Twenty-nine years later, that day still has not come.

    So, why do I stay? I stay because I laugh and learn every day. The children are funny, insightful, and honest. If my shoes don't match my outfit, they tell me. If my argument that Invisible Man is an important twentieth century classics doesn't convince them, they tell me.

    I stay because every single day is different. Some days, my lessons are great, and I have classes of students who are engaged in reading, writing and thinking. Some days, my lessons fall flat, and I realize that I need to start from scratch — even after 29 years.

    I stay because I love to see the children realize that they have learned something — whether it's how to craft an argumentative thesis sentence or how to understand the effect of repetition in The Declaration of Independence. I love to see the children write well; I love the feeling of reading a well-argued essay, and I love smiling as I write a final "Awesome job!" on a paper on which a student has worked hard.

    I stay because what I've learned in 29 years is that I do have a "real" job — the most real job there is. It's the one that leads to other jobs, that helps to create good thinkers who go on to be productive in our society, and that supports our community as it grows and times change. My job is among the ones that matter most.

    Roughly the size of a soda can, sitting on a bookshelf, a relatively harmless device(设备) may be turning friends away from your home. The elephant in your living room is your Internet-connected camera, a device people are increasingly using for peace of mind in their homes. But few stop to think about the effect these devices may have on house guests. Should you tell your friends, for instance, that they're being recorded while you all watch the big game together?

    "It's certainly new territory, especially as home security cameras become easier to fix," says Lizzie Post, president of the Emily Post Institute, America's distinguished manners advisors." I think it will be very interesting to see what manners appear in terms of whether you tell people you have a camera or not, and whether guests have a right to ask that it be turned off, if it's not a security issue. "Post wants to make clear that she's not talking about legal rights, but rather personal preference.

When it comes to security cameras, Post says it's a host's responsibility to make sure guests feel comfortable within their home. If the host casually acknowledges that there is a camera in the room by telling a story about it, that may be enough to provide an opening for a guest to say if they are uncomfortable.

    However, if a contractor(合约工)is working in your home, you don't need to tell them that there are cameras watching. Then again, the camera can also work in contractors' favor. "If anything does go wrong while they're in the house, they don't want to be blamed for it," she says. "In fact, the camera could be the thing that proves that they didn't steal the $20, or knock the vase off the table.

What will you do if you can't eat everything bought in the canteen(食堂)? {#blank#}1{#/blank#} According to a survey, what students waste every year could feed over 10 million people. 

{#blank#}2{#/blank#} According to Xinhua News Agency, the food wasted by Chinese people is about 50 million tons of grain every year, which could feed 200 million people. 

Food waste, which has become a global issue, serves as a mirror that reflects various cultural and social issues in different countries. In the west, for instance, consumerism, the belief that it's good to use a lot of goods and services, is often to blame for food waste. {#blank#}3{#/blank#}Chinese people are well known for being hospitable and generous. Many even feel that they lose face if their guests have eaten all the food. On campus, a generation of single children is less aware of the food waste issue. Students nowadays are well protected by their families and hardly have any concept of how much toil (辛劳) others go through in order to provide them with the food they eat. 

{#blank#}4{#/blank#}There are 925 million hungry people in the world. They don't have enough food to eat. And farmers work very hard to grow the crops. {#blank#}5{#/blank#}It's also important that everyone thinks about how they can do their bit to reduce food waste. Recently a campaign against food waste launched on line in China might make you think twice about being so wasteful.
