When I spent the summer with my grandmother, she always set me down to the general store with a list. Behind the counter was a lady like no one I'd ever seen.

    “Excuse me,” I said. She looked up and said, “I'm Miss Bee.”

    “I need to get these.” I said, holding up my list. “So? Go get them. ” Miss Bee pointed to a sign. “There's no one here except you and me and I'm not your servant, so get yourself a basket from that pile.”

    I visited Miss Bee twice a week that summer. Sometimes she shortchanged me. Other times she overcharged. Going to the store was like going into battle. All summer long she found ways to trick me. No sooner had I learned how to pronounce “bicarbonate of soda” and memorized its location on the shelves than she made me hunt for it all over again. But by summer's end the shopping trip that had once taken me an hour was done in 15 minutes. The morning I was to return home, I stopped in to get some run.

    “All right, little girl,” she said. “What did you learn this summer?” “That you're a meanie!” I replied. Miss Bee just laughed and said, “I know what you think of me. Well, I don't care! My job is to teach every child I meet life lessons. When you get older you'll be glad!” Glad I met Miss Bee? Ha! The idea was absurd.

    Until one day my daughter came to me with homework troubles. “It's too hard,” she said. “Could you finish my math problems for me?”

    “If I do it for you, how will you ever learn to do it yourself?” I said. Suddenly, I was back at that general store where I had learned the hard way to add up my bill by myself. Had I ever been overcharged since?

    Two thieves came to a house to steal something, they dug a hole in the wall of the house.

    There lived many mice in the house. The woman in the moonlight saw a mouse crawl (爬行) into the house. “Look! In comes one,” she said to the man in the house. He was so frightened that he hurriedly crawled out of the house and said to the one waiting outside, “She found me when I was just in.” But the thief outside didn't believe him, so he said, “Let us two try to crawl into the house together.” At that time two mice happened to crawl into the house, too. The woman saw the mice and shouted, “In come two, catch them!” The two thieves were terribly frightened. The man in the house said, “You saw them come in but where are they? I will catch them tonight.” The two thieves started running away at once.

    The two thieves wanted to make it clear whether they had been found or not the night before. The next day they acted as men selling sweet potatoes and came before the house. The man and the woman were ploughing in their fields. The rein (缰绳) broke and the woman came home for a rope. She saw two men selling sweet potatoes and wanted to buy some. She picked out two which looked like mice. At the time the man couldn't wait for her any longer in the fields and he ran back from the fields to hurry her up. The woman showed the sweet potatoes to the man and said, “How they look like the two of last night.” The man said, “I asked you to fetch a rope, why don't you hurry for it?” The two thieves ran away very quickly without their sweet potatoes.

    Plastic is easy, convenient, cheap and long-lasting, but it does great harm to the environment.

    Since plastic entered mass production, 8 billion tons have been produced – and we aren't very good at recycling. By 2015, 6,945 tons of plastic waste had formed, with around 9 percent of it getting recycled. About 79 percent of it ends up in landfills or around the environment, including the ocean. We may end up drowning in plastic before long.

    Chemists at Colorado State University have found a polymer（聚酯）that has many of the qualities of plastics – it's light, strong, durable and heat-resistant – but that can be changed back to its original small-molecule（分子）state for complete recycling. Even after being recycled, the polymer can be turned back into its plastic-like state, and this can be done quickly and cheaply.

    This new polymer has all the good qualities of plastics, yet it is relatively easy to make and to recycle. Making it requires room temperature conditions, a short reaction time to bond the monomer（单体）into polymers and only a small amount of the catalyst（催化剂）remains in the end product. It has a high molecular weight, stands up to heat and generally behaves like plastic. Recycling it requires similarly little effort. Mild lab conditions are required and so is a catalyst. Once applied, the polymers are once again monomers in a matter of minutes and can be used to create another product.

    But don't get too excited about this just yet. Scientists stressed that the polymer isn't ready for mass products just yet. There's still plenty of development to do, including making it more economical to produce and recycle.

    Walk down any British shopping street and you will find shops with strange names. Why is the opticians (眼镜店) called "Eyediology"? And who decided to name the butchers (肉铺) "Meat you there" ? What's going on?

    Puns are jokes based on words that sound the same. You've probably noticed that many words in English which are spelt in different ways and have different meanings are pronounced in the same way. Think about the name of the restaurant: "plaice" is a kind of fish so our restaurant is "the place" to eat fish. Butchers sell meat – so we'll "meet you there" – and opticians look after our eyes in a scientific way – so eyed – iology (ideology) is a name that fits. Hairdressers shear (cut) your locks (hair) and comb it – say the three words together quickly and you have the name of a famous detective. In shop titles and adverts, puns are used to get our attention.

    Puns are very old. The ancient Egyptians and Romans liked to pun. Shakespeare uses many puns in his plays – King Richard the Third (the son of York) brings "glorious summer" – just think about a word that has the same sound as son.

    Many people enjoy a good pun (pun / fun for all the family!) – others hate them. Puns aren't really designed to make you laugh. Here are some puns that might leave you asking for no more puns please. Have you heard about the bears who voted in the North Poll? Or the cheetah (印度豹) who couldn't be trusted at cards? Or how about the clever little Australian animal that had lots of koalaifications or the camel (骆驼) with no humps (驼峰) that was called Humphrey (and so was free of humps...)

    Puns can be funny but they sometimes make important points. Here's a fashion tip: "skinny genes make skinny jeans": so don't worry if your jeans don't fit. Look at your parents!

    They say the average person makes 35, 000 decisions a day. Yet in her new book, How Woman Decide, Therese Huston explores a widespread phenomenon that many women fail to notice. "There's a huge double standard when it comes to how men and women are viewed as decision﹣makers," explains Therese, a psychologist from Seattle University. Therese decided to write the book after looking at her bookshelf: At one end, there were bestselling books about how to be a clever decision﹣maker ﹣ all written by men and featuring interviews with men like athletes. At the other end were books aimed at women on gaining leadership skills and confidence.

    "Once those women are at the table, will their decisions be taken as seriously as men's？" Therese wondered. "Men are respected as decision﹣makers more than women, especially in the workplace, largely because there's this cultural belief that women are unable to make smart choices at work. "

    So, Therese set out to pick apart the stereotypes（固有印象）to see what scientific research had found. "Scientific research shows that men and women struggle with decision-making equally. The only disadvantage I found was that during the teenage years-teenage girls are more indecisive than teenage boys. Otherwise, there's little difference between the genders（性别）.

    However, there are some differences. "Women are more collaborative（协作的）, "says Therese. "A female boss is more likely to ask the opinions of those around her when making a choice. Women ask for input, which helps make better decisions. However, this is often seen as a weakness rather than a strength.

    Therese also found that during times of stress, men and women make different choices, and the outcomes are often better when women are involved.

    Study after study backs this view up. Neuroscientists Mara Mather and Nicole Lighthall from the University of Southern California studied the way men and women make decisions and found that in times of stress, they react very differently.

    During their study, which involved playing a virtual gambling（赌博）game, they found that when the females became stressed, they made smart decisions ﹣ quitting while they were ahead or taking safe bets. But when the men became stressed, they did the opposite, risking everything for a slim chance of a big win.

    I particularly enjoy the works of Greenwich Village poet Edward Field, whose interest in cinema led to a number of poems based on old monster movies (including many about Frankenstein and my favorite, Curse of the Cat Woman).

    There are so many to choose from! I love Robert Frost, especially "Mending Wall", mostly because he is my dad's favorite poet. However, personally I love Lnagston Hughes's poem "Dreams" because it always brings happiness to me. I am also a big fan of the older poems, such as Spenser's "One Day I Wrote Her Name Upon the Strand" because it is so simple, and "The Tyger" and "The Lamb" by William Blake because I love the language.

    My favorite poet is Suji Kwock Kim. Ever since I read her book of poetry "Notes from the Divided Country", I have been a big fan of her clear and thoughtful writing. My favorite poem of hers is "Borderlands", which she wrote in memory of her grandmother. It is a poem about her grandmother's experiences during the war.

    Hard to decide! But if I have to, I'd say Emily Dickinson. Her life was so wonderful and her opinions about life are also interesting. Her understanding of nature speaks to the heart of anyone who loves the outdoors! Dickinson also understood human nature very well. Her poems speak of love, loneliness, ect. Finally, my favorite poem by her is "I Never Saw a Moor". I love her thoughts!
