    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.

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?
