3 . When Alex Lin was 11 years old, he read a(an) ________ article in the newspaper, which said that people were ________ old computers in backyards, throwing TVs into streams, and dumping(丢弃) cell phones in the garbage. This was dangerous because e waste contains harmful ________ that can leak into the environment, getting into crops, animals, water supplies—and people.

Alex was really worried and decided to make it next project for WIN—the Westerly Innovations Network. Alex and six of his friends had ________ this organization to help solve community problems two years before.

But what could they do about this project with e-waste? The team spent several weeks gathering information about the harmful chemicals in e waste and their ________ on humans. They learned how to dispose (处置) of e-waste ________ and how it could be recycled. Then, they sent out a survey and found only one in eight knew what e-waste was, let alone how to dispose of it.

Alex and his friends went into ________. They advertised in the local newspaper and ________ notices to students, asking residents to bring their ________ electronics to the school parking lot. The drive lasted two days, and they ________ over 9,500 kilograms of e waste.

The next step was to set up a long-term e-waste drop-off center for the town. After some research, they’d learned that reusing is the best way to ________ electronic devices and it is seven times more ________ than recycling. So, they began learning to refurbish(翻新) computers themselves and distributed them to students who didn’t have their own. In this way, they could help students in the area and protect the environment at the same time.

For a________ solution to e waste, the drop off center wasn’t enough. Laws would have to be passed. In 2016,WIN helped ________ for an e waste bill in their town, which required companies that manufactured or sold electronics to take back e waste. The bill clearly ________ the dumping of e waste.

Because of the work of WIN, more and more people, like Alex and his team, are getting the message about safe disposal of e-waste. As Alex says, “Today’s technology should not become tomorrow’s harmful garbage.

6 . “WELCOME TO HELL, LADIES!” says Mr. Smith, the _________ of the adult ballet class. I force a smile as he presses down on my stiff (僵硬的)back, attempting to be a little more _________ .

When I was a little girl, I _________ elegantly dancing across the stage like the Swan Princess. With several reasons, my hopes of taking ballet lessons were killed. But every so often, usually while watching a brilliant performance of Swan Lake, those little _________ of unfulfilled desire would speak up and say that I should take lessons before it’s too late.

And here I am — more than 50 years — finally _________ for it.

I’m an absolute _________ , but 30 years older than the rest of the participants in the adult class. We are practising “port de bras”, a ballet term for the _________ of the arms. I flutter (挥动)my arms, awakening my inner _________ , “Your hands, they look like claws of a chicken,” Mr. Smith _________ , “No one wants to look at that. It’s ugly.” He points his finger at various body parts while __________ giving feedback, “Head up, neck long, chest proud, stomach in, back straight, bottom tight.” Every time he looks at me, I instantly know that I’ve missed something. So I take note of every previous adjustment to gain his approval.

After a few sessions, I find myself looking forward to taking ballet classes with a mix of anxiety and excitement. Between classes, I __________ my posture in every window I pass. I’m __________ . My hands are less claw-like and my posture a little more straight. And I constantly imagine I’m on stage, holding the audience entirely in my __________ .

Learning ballet as an adult has been a much bigger __________ than I expected, but I’m glad that I took action and that ballet still __________ to me as it did when I was a little girl.

8 . Christmas was near a season that we took seriously in our house. But a week or so before the 25th, my father would give each of his children ﹩20. This was the 1970s, and ﹩20 was quite a bit of money．

But I saw it _______．My father trusted me to have the _______ to spend money wisely. Even better, he gave me the _______to get it. On a very basic level ，my father was giving me a shopping spree（狂欢）every year. But he was also giving me charge over my own fun, trusting my ability to manage money and making me feel like a/an_________. He didn't buy me Sherlock Holmes, but he gave me the means to walk into the bookstore and choose it for myself, so it felt like a gift from him．

My mother had a/an _______for giving me what I needed, usually   right at the moment I needed it most. This was when I was 25, I_______at being an adult on my very first try. I had quitted my _______job but had no new one. But when my mother   paid me a visit, I_______a good show, telling her I had started my own company．

My mother knew that I was trying hard and failing at that time. It wasn't until _______she left that I noticed at the foot of my bed an envelope thick with ________．She knew how ________I needed it．She knew that had she just shown up with groceries，or offer to pay my rent, she would have made me feel much ________．The cold，hard cash meant she was helping me. And, funnily enough, the__________with which she gave the gift felt like she was giving me space to__________my life and preserve my dignity．My mother and father both did the same thing. One was giving me the means to take my own decisions，and the other was giving me a second __________ when those decisions had cost me dearly．

9 . Suppose that 54.3 percent of your country’s population had cancer. That figure might set off a nationwide _______—a search for something wrong with people’s diet, the environment, acidity levels. In fact, that’s the percentage of Americans who show a positive skin response to one or more allergens.

The ______ of allergy—sneezing, itching, rashes—are signs of an immune system running amok, attacking foreign invaders—allergens—that mean no harm. Allergies _______ kill. They just make the sufferer miserable—sometimes for brief periods, and sometimes for life.

Allergies are essentially an epidemic of modernity. As countries become more industrialized, the percentage of population affected by them tends to grow higher. There are remote areas of South America or Africa where allergies are virtually _______.

Here’s how an allergy develops: One day, a body is exposed to a protein in something that seems perfectly ________—the wheat flour, say, in a home-baked muffin. But for some unclear reason, the body looks at the protein and sees trouble. There will be no _______ at first, but the body is remembering—and planning.

That first exposure causes the immune system to produce an antibody called IgE (immunoglobulin E). Then IgE antibodies attach to certain cells, called mast cells, in tissue throughout the body. There they stay like _______ soldiers waiting for war. With a second exposure, even months later, some of the allergen binds with the IgE on the mast cell. This time the mast cell releases a flood of _____ chemicals, which cause inflammation and itching.

There is, unquestionably, a _______ component to allergies. A child with one asthmatic parent has a good chance of developing the condition. If both parents have asthma, the chance of occurrence increases.

Still, the rise in allergies is too rapid to be explained ________ by genetics. “The genetic pool can’t change that much in such a short time,” says Donald Leung, director of an allergy-immunology program in the U.S. “There have to be environmental and _______ factors as well.” Dozens of theories have blamed everyone from urban landscapers for _______ male plants (the ones that produce pollen), to women who don’t breastfeed. Breastfeeding, the theory goes, confers greater protection against allergies.

Another probable factor: diet. “Reduced fresh fruit and vegetable intake, more processed food, fewer antioxidants, and low intake of some minerals—these are all shown to be a _______,” says professor of medicine Harold Nelson, considered one of the foremost experts on allergies in the U.S.

Another prime culprit: environmental pollutants. Exactly what pollutants and in what quantities are a _______ of heated debate. One of dozens of examples: Children who are raised near major highways and are exposed to diesel fumes from trucks register a(n) ______ sensitivity to allergens they already react to.

10 . When you walk on the streets of cities like New York and Washington, D.C., it’s hard to miss the sculptures. Many mark parks and neighborhoods. Historic figures often can be seen standing upright. Or they can be seen sitting on their horses, stoically striking a pose. More often than not, these statues have another thing in common. It’s their _______. The majority of public statues in the United States are of men.

Of the estimated 5,193 public statues depicting historic figures on display throughout the U.S., only 394 are of _______. This is according to a story written in 2011 by The Washington Post’s Cari Shane. Compounding this number, none of the 44 memorials maintained by the National Parks Service, like the Lincoln Memorial or the Jefferson Memorial, specifically _______ women.

A group is looking to change this _______. The group is called Where Are The Women? Recently, it successfully campaigned to have statues of women’s rights pioneers Susan B. Anthony and Elizabeth Cady Stanton added to New York’s Central Park. The park, _______, had no statues of non-fictional women on its grounds.

The _______ of women’s representation poses a problem. Leaving their stories out from public art _______ the significant roles that women have played in history.

Currently, few of the statues that do show women on city streets are _______ historic figures. Instead, women often appear as archetypes. They are symbols of abstract concepts. Or they are nameless figures in a memorial.

One campaign isn’t enough to solve ongoing issues of gender discrimination and _______ in the U.S.. But by pressing to honor real women from history, cities can restore them to a story that has __________ them for so long. After all, as it stands now, only five public statues of historic women remain in New York City. The statues are of Joan of Arc, Golda Meir, Gertrude Stein, Eleanor Roosevelt and Harriet Tubman.
