More than anything else in the world, Jayden Hairston wanted to learn how to sing. _________, his elementary school in Yonkers didn't _________ the music instruction he needed. So he begged his parents to sign him up for after-school lessons.
His mother said, ''Ever since I could _________, he has been singing and dancing for the family. '' She wanted to help her son to do whatever he loved, but private lessons were too _________ for the family where there was only one breadwinner.
Then Jayden began researching after-school arts _________ on the Internet. Luckily, he soon _________ the website of Harlem School of the Arts (HSA) in New York City. There, he could _________ singing and dancing lessons. It was a bit far from Yonkers. But he _________ his parents to take him for a visit.
That was three years ago. Now Jayden is one of HSA’s most _________ students. He takes singing, dancing, or theater lessons almost every day after school. Last year, he performed in seven productions. ''When I'm at HSA, I don't want to leave, '' he says. ''It's made me more __________. I feel better about myself, '' Jayden says.
Like Jayden, many poor students across the United States have __________ access to arts instruction in schools. HSA is one of many nonprofit groups that __________ this gap (缺口) by offering cheaper online arts classes which most families can __________. These groups are usually funded by donations.
A Harvard University study found that arts instruction does not straightly raise students' __________ in math and English. However, that doesn’t mean arts education isn’t __________. Arts train a set of thinking skills __________ those measured by test scores. It can also offer another __________ for children who may not __________ good scores in such exams.

How to DIY Your Own Mask
During the outbreak of COVID-19, one of the must-have items is the mask. However, many countries are in bad need of medical masks and other protective equipment. 1. But we can make our own masks which can be used repeatedly. Now, let’s look at the most popular DIY method for soda bottle gas masks.
2. And it doesn’t require huge skills. With necessary materials and a little training, it can be made in 15 minutes.
To make such a mask project, you’ll require a sharp cutting tool, a market, glue, a 2-liter soda bottle, rubberized foam insulation strip (泡沫橡胶绝缘条) and one N95 mask. Total cost may be $5.
First, you’ll have to clean the 2-liter plastic bottle. After that, draw a U-shaped area using the marker. 3. Then start with a smaller cut and work your way up from there. Cut away the bottom of the bottle and you’ll end up with a basic shape.
Next, use the rubberized foam insulation as a seal for the edges of the bottle. 4. This will serve as a resting place for the N95 mask. Then cut off the N95 mask’s edging carefully. And place is inside the neck of the bottle. The elastic bands (橡皮筋) from the N95 mask will be used to secure the gas mask firmly on your face. Then a DIY gas mask is completed.
Do remember to keep the gas mask stored in a well sealed plastic bag. 5.
A.In this way you can make good use of the bag.
B.This can prevent it from getting polluted.
C.The soda bottle gas mask is very simple to make.
D.In this situation it is hard for people to get enough masks.
E.It should be big enough to fit your face and yet not too big.
F.Actually, the idea of DIY gas masks dates back to WW II.
G.You should also make a circle of foam insulation inside the bottle.
Sometimes, you just can’t say no to another spoonful of ice cream and maybe one more after that. Why not? You deserve it.
There’s no need to beat yourself up about it later. The truth is that you were probably bound to do that from the very first spoonful. That’s because there is a switch in your brain, and for whatever reason, it can get stuck in the “on” position.
According to a new study, this impulse (冲动) control may come down to a very specific circuit (回答) in the brain which occasionally produces melanin-concentrating hormone, or MCH—a chemical linked with our desire for food or drugs. And that circuit always says yes.
By manipulating this circuit, it is possible that we might be able to develop cures for overeating that help people stick to a diet without reducing normal appetite or making delicious foods like donuts less delicious.
For their research, the scientists treated rats to a self-serve buffet. Bur the treats were on a timed delivery system, making tasty food every 20 seconds, and only when a rat pressed a lever (杠杆). Hit that lever too early—as impatient test subjects occasionally did—and the counter would start from scratch. Lever-happy rats would have to wait another cycle before the food became available again.
A second experiment offered the rats two dining options. Push Lever A and get an immediate small reward. Pushing Lever B meants waiting for around40 seconds, but the food reward would be much bigger. Guess which lever those impatient rats were most food of? That’s right. They picked the now-now-now switch.
Their impulsiveness, however, rose sharply when scientists gave the rats MCH. These animals become more impulsive. MCH, it seemed, could talk rats into loosening its inhibitions (拘束). The result? More please.
Researchers can now see where that conversation between the brain’s reward system and its impulse control center takes place. The next step will be to map it—and potentially influence the discussion. It may eventually be possible to control a food-eating impulse.
1.Which of the following can best replace the underlined word “manipulating” in paragraph 4?
A.Strengthening. B.Controlling.
C.Classifying. D.Creating.
2.What would happen when a rat pressed a lever earlier than the fixed time?
A.A bigger food reward would appear.
B.Tasty food would be delivered much sooner.
C.Longer time would be needed for food to appear.
D.The lever would be stopped form delivering food.
3.Why did the researchers conduct the experiments?
A.To find out the effect of MCH on animals.
B.To prove rats are also greedy for more food.
C.To study how levers influence rats’ impulse.
D.To show rats and humans have similar impulse for food.
4.What is the best title for the text?
A.What Is the Effect of Your Impulse?
B.What Can You Do to Resist More Food?
C.Why Can’t You Say “No” to Your Impulse?
D.Why Do You Always Give in to One More Mouthful?
We’re drowning in plastic. If you want to reduce your own contribution to the plastic pollution problem, recycling might seem like an easy solution.
But what happens after you clean out those plastic containers and pour them into a recycling bin? Unfortunately, the outcome isn’t as rosy as many people think; recycling is unlikely to give plastic to-go containers new life. “Of all the waste produced in 2017, only 8.4% of it eventually got recycled. It’s not that consumers aren’t motivated to recycle or that they don’t have ready access to recycling programs; the United States simply doesn’t have the proper facilities (设施),” said John Hocevar, a marine biologist with Greenpeace USA.
A recent report surveyed the United States’ 367 materials recovery facilities—the facilities that sort our recycling—and found only plastic bottles were regularly recycled. The fate of most other types of plastic such as packaging usually ends up being buried or burnt.
Not all plastic is created equal. If you turn over a transparent plastic bottle, like those used to hold water, you’ll notice a number “1” inside a triangular recycling symbol. Non-transparent jugs, like the kind that hold milk, get a “2”. At materials recovery facilities, or MRF’s, plastics get sorted based on these numbers, which indicate how recyclable they are.
Numbers 1 and 2 are relatively recyclable. Recycling gets more difficult with higher numbers, called “mixed plastic”. This waste makes up around 69% of all the plastic we use. It’s much more expensive to process than numbers 1 and 2.
So what the United States needs is facilities equipped to process other kinds of plastic. But Hocevar came up with a different solution: “The really simple answer is that we have to stop making so much throwaway plastic.”
That said, is recycling worth it? For bottles labeled (贴标签) “1” or “2”, the answer is “yes”. There’s also a growing market for plastics labeled “5”. For other numbers, Hocevar’s answer was simple: a resounding (响亮的) “no” on numbers 3, 4, 6 and 7.
1.Which problem is the USA facing according to the text?
A.People don’t know the best way to recycle.
B.Ready recycling programs are not accessible.
C.People lack awareness about plastic recycling.
D.There isn’t suitable equipment for plastic recycling.
2.What may John Hocevar think of plastic recycling in the USA?
A.Productive. B.Promising.
C.Unsatisfying. D.Controversial.
3.What information can the numbers on plastic bottles convey?
A.Whether it is easy to recycle them.
B.The recycling technology they need.
C.They places where they were produced.
D.Which dustbin we should put them into.
4.What should we do with plastic according to Hocevar?
A.Give up the use of plastic.
B.Develop more cheaper facilities.
C.Only recycle plastics labeled 1 to 5.
D.Reduce the production of mixed plastic.
Tyler and I stopped by our corner store. A few police cars caught Tyler’s attention. “Mom, can I use my allowance money and buy the policemen some doughnuts to say ‘thank you’?” he asked.
“Certainly!” I said, feeling proud that I was achieving my aim to raise my children to be grateful, tender-hearted and caring.
After we left the store, Tyler asked a question that would change our lives and the lives of countless others forever.
“Why were the police so happy about the doughnuts?”
I explained some people are not always friendly to police officers. Tyler was very sad to hear this, and instead of shrugging it off, he said that he was going to thank every cop in America and buy them each a doughnut!
I was shocked, but it never occurred to me to say “no”. In fact, I thought it was an excellent but unachievable idea. I suggested many other options, but nothing was enough for him on the newfound mission (使命).
I didn’t know how to put this passion into action, but I knew one thing: Tyler had found his purpose, and it was my duty to help him. I e-mailed our local office and asked if Tyler could host a thank-you event for them. They were delighted. At the event, they called Tyler “The Donut Boy”, a name that has become known throughout the nation.
Then we kept planning thank-you events and many caring people joined in. We were invited to TV stations, and flew to Washington, D.C. for National Police Week. It has been three years since a simple act of kindness sparked a wonderful idea in an eight-year-old boy,
In forty-eight states, more than 90,000 doughnuts have been delivered so far, with no end in sight. We’re made memories that will last a lifetime, but most importantly, we have served those who serve us daily and made our mark on this world.
1.What quality of Tyler made the author feel proud?
A.Kindness. B.Honesty.
C.Confidence. D.Independence.
2.How did the author react to Tyler’s wish to thank all the police at first?
A.She tried to change his idea. B.She told him it was impossible.
C.She praised him for his ambition. D.She expressed her doubt about it.
3.What can we infer about Tyler?
A.He is eight years old. B.He has become world-famous.
C.He’s influenced many people. D.His mission has been completed.
4.What conclusion can we draw from the text?
A.Well begun, half done. B.Strike while the iron is hot.
C.God helps those who help themselves. D.Nothing is impossible to a willing heart.
