No poem should ever be discussed or “analyzed”，until it has been read aloud by someone，a teacher or a student．Better still，perhaps，is the practice of reading it twice，once at the beginning of the discussion and once at the end，so the sound of the poem is the last thing one hears of it．

    All discussions of poetry are，in fact，preparations for reading it aloud，and the reading of the poem is，finally，the most telling “interpretation” of it，suggesting tone，rhythm，and meaning all at once．Hearing a poet read the work in his or her own voice，on records or on film，is obviously a special reward．But even those aids to teaching can not replace the student and the teacher reading it or，best of all，reciting it．

    I have come to think，in fact，that time spent reading a poem aloud is much more important than “analyzing” it，if there isn't time for both．I think one of our goals as teachers of English is to have students love poetry．Poetry is “a criticism of life” and “a heightening(提升)of life”．It is “an approach to the truth of feeling”，and it “can save your life”．It also deserves a place in the teaching of language and literature more central than it presently occupies．

    I am not saying that every English teacher must teach poetry．Those who don't like it should not be forced to put that dislike on anyone else．But those，who do teach poetry must keep in mind a few things about its essential nature，about its sound as well as its sense，and they must make room in the classroom for hearing poetry as well as thinking about it．

    As soon as a person dies, decomposition(分解) begins. And the first visitors arrive. “Within 5 to 15 minutes of death, flies or other insects begin to colonize the body.” says Rabi Musah, an organic chemist at the University at Albany.

    She says different species turn up at different stages of decomposition. “So because of that, depending upon what entomological(昆虫学的) evidence you find, you can learn something about when the person died in terms of the timing of the death.”

    Flies don't tend to stick around when disturbed by detectives. But they do leave behind eggs. The eggs are hard to tell apart by appearance alone, so specialists raise them until they hatch, a few weeks later—and they get a species ID and, with a little guesswork, a person's time of death.   But Musah has come up with a more time-saving approach: chemical analysis of the eggs. She and her team investigated that method by first harvesting flies with pig-liver traps hidden throughout New York City. They collected the trapped flies and then chemically analyzed their eggs. And it turns out each species of fly egg has a unique chemical fingerprint—enough to tell the eggs apart without raising the eggs to maturity. The study is in the journal Analytical Chemistry.

    Musah and her colleague Jennifer Rosati are now testing the method on a real case. “And once we do that we will be publishing some case studies to illustrate(阐明) that this is a method that can be used, and hopefully eventually it's something that will stand up in court, and something that could speed up detective work—or help deal with a cold case.”

    Good afternoon, and welcome to England. We hope that your visit here will be a pleasant one. Today, I'd like to draw your attention to a few of our laws.

    The first one is about drinking. Now, you may not buy wine in this country if you are under 18 years old, nor may your friends buy it for you.

    Secondly, noise. Enjoy yourselves, but please don't make unnecessary noise. We ask you to respect other people who may wish to be quiet.

    Thirdly, crossing the road. Be careful. The traffic moves on the left side of the road in this country. Use pedestrian crossings（人行道） and don't take any chances（冒险） when crossing the road.

    My next point is about rubbish. It isn't a law to drop rubbish in the street. When you have something to throw away, please put it in your pocket and take it home, or put it in a dustbin.

    Finally, about smoking. It is against the law to buy cigarettes if you are under 16.

    If you request any help, you should contact the police, who will be glad to help you. You can call, write, or directly go to ask any policeman.

    I was in a rush as always, but this time it was for an important date I just couldn't be late for! Thinking of my upcoming evening, I hurried into a store to pick up some flowers, for I did not want to be late for this date. When I paid the bill at a checkout counter, I found myself behind an elderly woman who seemed in no hurry when she paid for her groceries. She looked up at me and smiled. It was a nice smile –warm and friendly –and I returned her gift by smiling back.

    “Must be a special lady, no matter who will be getting those beautiful flowers,” she said.

    “Yes, she's special,” I said, and then to my embarrassment, the words kept coming out.

    “It's only our second date, but somehow I am just having the feeling that she's 'the one'. Jokingly, I added,“The only problem is that I can't understand why she'd want to date a guy like me.”

    “Well, I think she's very lucky to have a boyfriend who brings her such lovely flowers and who is obviously in love with her,” the woman said.” “My husband used to bring me flowers every week –even when times were hard and we didn't have much money. Those were wonderful days; he was very romantic and – of course – I miss him after he died.

    I paid for my flowers as she was gathering up her groceries. I walked up to her, touched her on the shoulder and said,“You were right, you know. These flowers are indeed for a very special lady.” I handed her the flowers and thanked her for such a nice conversation.

    It took her a moment to realize that I was giving her the flowers I had just bought.“You have a wonderful evening,” I said. I left her with a big smile and my heart warmed as I saw her smelling the beautiful flowers.

    I remember being slightly late for my date that night and telling my girlfriend the above story. A couple of years later, when I finally worked up the courage to ask her to marry me, she told me that the story I had told her that night helped me win her heart.

How much of your monthly grocery list ends up in the garbage? A new study reveals the average American spends nearly $1,500 per year on food they'll never eat.

A recent survey of 2,000 Americans reveals the average shopper wastes $1,493.93 on food per year. That's almost a fifth of their grocery bill after every shopping trip. One tenth of respondents claim they "never" purchase food they don't end up eating, while three in 10 say this is something they "always" do.

Half of respondents prefer to head to the grocery store alone, and when they do, half are more likely to stick to their list and 36% are less likely to buy food they don't want or need.

Keeping the list in mind is important, as 38 percent are more likely to let food be wasted if it wasn't originally on their shopping list. Seven in 10 add that when they go to the store on an empty stomach, they're more likely to buy foods they won't eat. So they don't do that that way. Some respondents appear to be in a wasteful cycle when it comes to food waste. Nearly half usually buy and end up wasting the same food every month because they think they'll get around to eating it.

"We can all do better to limit food waste by sticking to grocery lists and, when we get home, prioritizing eating our foods that are_perishable, like fruits, vegetables, and dairy products" says Avocado Co-Founder and CMO Mark Abrials in a statement.

Three-quarters feel guilty about throwing away uneaten food because it's a waste of money — and 48 percent feel the same, due to the harm food waste causes to the environment. "When it comes to food waste, nobody is perfect," Abrials adds. "But in order to consider our environmental impact, not to mention wasted money, we think it's essential to be thoughtful about everything we purchase — whether that's food, mattresses or other goods."
