1 . Within the environmental movement, the question often arises whether global warming can be mitigated (缓解) by planting more vegetation. The idea is that the plants will consume carbon dioxide (CO2) that is causing the warming, while producing oxygen for us to breathe. This is acceptable on condition that global warming is indeed caused in some way by CO2 in the air.

However, actual scientific debate on the issue has shifted away from CO2 as the probable cause, especially after the findings that the temperatures changed 800 to 1000 years before carbon dioxide changed. In other words, CO2 levels are an indicator of temperature change, not a cause.

While there is nothing we can do to control the global climate, there is still a lot we can do to improve our local climates. Land use is the biggest decisive factor of local temperature and air quality. On clear days, the temperatures in big cities can be 5.6 degrees Centigrade higher than in the countryside around them. This is because the concrete (混凝土) of sidewalks and buildings and the asphalt (沥青) of roads take in sunlight and transform it into heat. Some get so hot, one could cook an egg on them! These vast surfaces of man﹣made stone also store lots of heat, which they radiate (散发) all night long. Just before sunrise, when the earth should be its coolest, roadways are still warm to touch.

If vegetation was blocking the Sun from the sidewalks and roads, the vegetation would absorb the sunlight, fueling the plants’ oxygen-making engines, and the rock would stay at surrounding temperatures. The easiest and most obvious choice is trees, particularly wide-reaching trees like the oak. Another possibility, especially outside the city centre, could be vine-covered trellises (棚架).Covering rooftops with grasses or other short vegetation reduces a building’s cooling cost as sharply as having trees or trellises that provide shade for windows does.

The reason why vegetation does not warm the air like rock does is that plants take water from the ground and evaporate (蒸发) it through their leaves. The Sun’s energy isn’t radiated as heat — it is used to change water into water vapor. The evaporative cooling works so well that the leaves stay 5.6 to 8.33 degrees Centigrade cooler than they would have been without water. While we can’t improve global climate, increased vegetation can help cool local climates.

2 . Research has shown that when we volunteer — where we devote ourselves to helping others — we actually end up benefiting too. Our happiness grows. We feel more satisfied with life. We even have more energy and creativity. Basically,we have more to give.

I’ve noticed a pattern with my friends. Sometimes,they get into the habit of gossiping about others. They will constantly complain about their bosses or coworkers. It seems as if they get caught in this loop(闭环) of complaining,and their frustration distracts them in other parts of their life. When this happens,they become uninterested in new events or become annoyed by their colleagues or things that happen at work.

Meanwhile,I’ve also seen other friends go out of their way to help someone on their team or to help out on a project that have very little — or even nothing — to do with their main work. Although it seems like they won’t receive anything in return,my friends benefit from these interactions. My friends have told me about the stronger relationships they’ve built at work and the fun they had working on new and interesting projects. They’ve told me about how the people they helped before have returned the favor later on. Not only that,but they have even talked about times where their boss recognized them for their work or when they were informed in advance about upcoming projects.

We often think that when we help someone else,we aren’t doing anything for ourselves. But we actually often end up getting back just as much as we give. When we step in to help someone,we often turn out to be helping ourselves as well.

Research shows when we help others，we end up     1     too.

Our happiness grows. We feel more satisfied. We are more    2    . We     3    .

We have more to give. We often turn out to be     4    .

3 . With mouth-watering thoughts of a tasty sandwich on your brain, you unwrap a loaf of bread and see a patch of green mold (绿霉).     1    

Maybe you hear the voice of your mom or dad in your head,   “Don’t be childish! Just eat around it!”“ Or you feel the guilt of food waste. By some estimates, about one-third of all the bread made in the U.S is never eaten.     2     ”We don’t advise cutting off mold of the bread, because it’s a soft food, “ Marianne Gravely, a senior specialist for the U.S. Department of Agriculture, tells NPR. ”With soft food, it’s very easy for the roots (of the mold), or the tentacles, or whatever scary words you want to use, to penetrate into the food“

    3    

Mold is a type of fungi, and comes from the same family as mushrooms. In fact, if you look at mold under a microscope, you will find that it looks like very skinny mushrooms, according to the USDA. It has a stalk with spores on top which form the blue-green moldy part that you see on food.     4     The network of roots is impossible to see. So what looks like ”clean" bread may actually be full of this tangle of mold threads.     5    

A．Yes, you’d better throw that loaf away.

B．When throwing away moldy food, put it in a small paper bag or wrap it in plastic.

C．Do you cut off the disgusting part or throw away the entire loaf?

D．What you don’t see are root threads underneath that damage the foods they live on.

E．But science seems to overrule the guilt and parental pressure, at least in this case.

F．In some cases, a few molds produce poisons that make people and animals sick.

G．Besides, moldy food may also have invisible bacteria growing along with the mold, says the USDA.

4 . It was a freezing cold winter’s night back in 2017, as Adrian Young raced his father, Will, to their car in the empty carpark of a local restaurant in Southern Queensland. His mother, Jennifer, followed with Adrian’s younger sister. They were hurrying to the car to escape the cold 1℃ night. But as they reached the car, Adrian’s eyes rested on the back of the carpark, where a man was lying on a makeshift bed of blankets. “I felt bad as I was trying to get out of the cold and he was about to sleep in the freezing cold,” says Adrian.

Will went over to the man to see if he was safe, and also gave him about $20, hoping he could put it towards some hot food or perhaps a warm overcoat.

Will and Jennifer quickly forgot about the encounter (相遇), but Adrian couldn’t shake the feeling that he hadn’t done enough. For the first time he realized that there were lots of other homeless people without a warm bed.

Adrian told his parents he wanted to buy the homeless man a house to live in but when he discovered this wasn’t possible, he kept on asking questions. “I want to do more to help so I decided that I would use my own money and take him a backpack with some warm clothes and special food,” he says.

The fifth grader didn’t want to stop there so, together with his mother and little sister helping out, he decided to make 50 care packs with necessities (必需品) like toothbrushes along with special treats. The family sent the bags to Base Services, an organization helping the homeless. “We wanted people to feel cared for and know we’d put these bags together with love, ”says Jennifer, who also made sure to add the label (标签)‘I care for you’, with love onto every pack.

Since then, Adrian and his family have created more than 100 care packs and raised almost $5,000 on the fundraising site www. gofundme. com.

5 . Zhang Guimei Awarded CPC’s Top Honor July 1 Medal
1 July 2021

On June 29 this year, Zhang Guimei was awarded CPC’s top honor July 1 Medal at the Great Hall of the People in Beijing. At the ceremony. she said she did all this out of her gratefulness and love for the country, as well as the original aspiration and mission of a CPC member.

Zhang Guimei, who has dedicated her 40 years to education at China’s southwestern border, is a principal motivating young girls from impoverished families in mountainous areas.

Zhang was born in Mudanjiang, Heilongjiang province in 1957. At 17, she came to Dali in Yunnan province to support the development of border areas, where she stumbled into teaching and started a career as an educator. After her husband’s death in 1996, she went to teach in Huaping county, Yunnan’s Lijiang. Five years later, she established a chilren’s home and worked as a part-time president of it. The organization adopted a total of over 170 children, who call Zhang mom though she has never given birth to a child..

While teaching there,she saw many girls drop out of school due to poverty. To change the destiny of the girls in the mountain, Zhang started her preparation to build a free all-girls high school in 2002. In 2007, Zhang went to Beijing for the 17th CPC National Congress as a deputy. Her report titled “I have a dream” delivered at the meeting made her dream of building a free all-girls high school known to all. Later, both the Lijiang and Huaping governments sponsored her with a million yuan. A year later, Zhang’s school was completed, becoming the first free all-girls high school in China. During the past 13 years, the school has nurtured over I,800 students who have made it to universities.

With no offspring and property, Zhang lives in a dormitory building with her students. She has donated all her cash awards, donations from others, and most of her salaries, more than a million yuan, to the children and other people in need. She suffers from 23 diseases, but she is still working selflessly.

Her story has moved millions of Chinese people and is now written into a newly published Brief History of the People’s Republic of China.

6 . “Who loves pizza?” is a question you almost never have to an American. A better question might be “Who doesn’t love pizza?”   Now, there’s a place for all pizza lovers to gather: the Museum of Pizza. It can be found in America’s pizza capital—New York City.

A company called Nameless Network came up with the idea for the museum, known as “MoPi” for short. “It’s often that the simplest ideas are the best. The company used the popularity of pizza as a way to get people “looking at art and hearing about history in a different way,” said Alexandra Serio, who is with Nameless Network. Many kinds of artists were asked to create art works about pizza. They, in turn, provided large photographs, sculptures and huge installations. So far, the museum has had lots of visitors. More than 6,000 people came through the door when it opened this month.

Visitors seem to love MoPi’s bright colors, which makes it perfect for taking selfies and other photographs for social media.

Nene Raye, from New Jersey, was a recent visitor. Raye didn’t expect to see what she saw—and she was happy about that. “Honestly, I thought it would be, like, more of a traditional museum,” She said. But instead, Raye got some of everything. “So You get a little bit of education and then some fun, which I love,” she said.

Lydia Melendez made plans to visit the pizza museum in April. For her, the experience was worth the wait. “I thought it was going to be kind of boring,” she said. She had imagined walking in and finding books on how to make pizza. But she was very pleased when her actual experience was different than what she had imagined.

While pizza may be what has captured the interest of crowds, the point of the Museum has been to help people exposed to fine arts world.

1. What’s the function of the two questions in the first paragraph?

A．To make a comparison

B．To introduce the topic—the Museum of Pizza.

C．To inform people of the popularity of Pizza.

D．To advertise the food.

2. What do we know about the Museum of Pizza?

A．The Museum took advantage of the long history of Pizza to attract visitors.

B．The Museum received over 6000 visitors during the first two months.

C．Both Nene Raye and Lydia Melendez didn’t expect the Museum to be so different.

D．The Museum is appealing in that it combines education and fun.

3. What’s the purpose of the museum?

A．To make art available to people

B．To draw attraction and earn more money

C．To change people’s attitude to museums

D．To enrich city people’s daily life.

4. What’s the best title for the passage?

A．Bored? Go To The Museum Of Pizza!

B．Pizza Museum Serves Up “Tasty” Art.

C．The Hook Of The Museum.

D．Simplicity Has Its Power

7 . Napping is a common habit for many of us.     1    For example, it can improve memory and creativity. However, it can also have negative effects if done in the wrong way.

The ideal nap length, according to scientists, is 20 to 25 minutes. Any longer and you'll fall into a deeper sleep cycle, which lasts for about 90 minutes.     2    

There is a term for this short, effective nap: a power nap. It is a short sleep of 20 minutes or less which ends before the occurrence of deep slow-wave sleep, intended to quickly refresh the napper.

    3    Salvador Dali outlined tips for the one-second micro-nap, including sitting upright, key in hand and upturned plate beneath. Once asleep, the key will drop and the ensuing clang ensures instant revival.     4    

Exceptions to this include essential naps when sick, which are often longer because our bodies require more sleep when dealing with an illness.     5    This is because children have a higher sleep requirement than adults.

A．In fact, many celebrities in history are power nappers.

B．Napping brings us both positive and negative effects.

C．Take a nap between 1:00 and 2:30 instead of 3:00 or 4:00 p. m.

D．Albert Einstein deployed a similar technique, using a pencil instead of a key.

E．Napping has many benefits.

F．Also, fulfillment naps in children should not be limited to 20 minutes.

G．This means when you wake up you will experience “sleep inertia” (睡眠惰性) .

8 . An air-conditioner has become a sign of middle-class status in developing nations. But as air-conditioners appear from windows and storefronts across the world, scientists are becoming increasingly alarmed about the impact of the gases on which they run.

The oldest CFC coolants used in air-conditioners, which are highly damaging to the ozone layer, have been largely rejected from use; and the newest ones, used widely in industrialized nations, have little or no effect on the ozone layer. But these newest gases have an another impact — they contribute to global warming thousands of times more than CO2 does, the standard greenhouse gas. Indeed, the leading scientists in the field have just calculated that if all the equipment entering the world market uses the newest gases currently employed in air-conditioners, up to 27 percent of all global warning will result from those gases by 2050.

So the treatment to cure one global environmental disaster is now seeding another. "There is precious little time to do something, to act," said Stephen O. Andersen, the co-chairman of an international organization's technical and economic advisory panel.

Promising technologies wait, blocked in the wings. In China and a few other countries, room air-conditioners using hydrocarbons — which cause little warming or ozone damage — are already coming off assembly lines in small numbers but have not yet been approved for sale, in part because the chemicals are flammable (易燃的).Yet in Europe, refrigerators that cool with hydrocarbons have been in use for years, and some companies in the United States, such as Pepsi and Ben and Jerry's, have recently changed in-store coolers from HFCs to hydrocarbons as part of sustainability plans. But the patent is being argued. And some governments have still not finished safety testing.

Mr. Wypior, whose agency is trying to promote climate-friendly air-conditioning industries in India and China, said: “The technologies are available. They're well known. They're proven— though not at scale. So why aren't we moving?”

1. What's Paragraph 2 mainly about?

A．Air-conditioners' influence on the ozone layer.

B．Scientist's efforts to control the greenhouse gases.

C．The seriousness of global warning faced by the whole world.

D．The harmful effect of the newest gases used in air-conditioners.

2. What does the underlined sentence in Paragraph 3 mean?

A．These newest gases are used in the wrong direction.

B．These newest gases should be banned from producing

C．These newest gases will lead to global warming.

D．These newest gases carry both benefits and harms..

3. Why are hydrocarbons not widely used in air-conditioners?

A．Hydrocarbons are mainly used in refrigerators.

B．People are still arguing about their security.

C．Hydrocarbons are not friendly to the environment.

D．Most countries haven't mastered the related technologies.

4. What's Mr. Wypior's attitude to climate-friendly air-conditioner?

A．Positive.	B．Negative.
C．Unconcerned.	D．Indifferent.

9 . How to Select a College

Second term of junior year can be a scary time. The college application process is approaching and your fears are becoming more realistic. You may not get into every college you apply to, which is why it’s important to have “safety schools” that are practically guaranteed to accept you. It is also important to have “reach schools” that are more difficult to get into but offer a greater education.     1     Then there is the “dream school” --- the one you would do almost anything to get into.

Here are my tips on selecting a college:

Do you have any idea where you want to go? Juniors should make a top-10 list that includes three safety, three reach, and four dream schools.

    2     Sites like Princeton Review.com and College Board.com are very helpful in finding out what ACT or SAT score may be required to be accepted, as well as what sets a college apart from the others, and if it offers extra-curricular activities in which you are interested.

Apply and visit. After you have thoroughly researched your top 10 schools, narrow the list to five. These are the colleges to which you will most likely apply. Check deadlines, but applications should usually be sent by November.     3     If you are unable to visit, email the admissions office with any questions.

    4     Your acceptance and sadly rejection letters will come in April. Now, this may sound easy, but it is necessary to list the advantages and disadvantages of all the schools where you are accepted. Examine every fact you know about the college. Whichever school has the highest pro to con ratio should be your pick.

Have fun in college! You likely made the right choice, but college life may be difficult so always remember to study hard, get plenty of sleep, and fasten your seatbelt ---     5    

A．Choose wisely.

B．Find out the entrance requirements of these ten schools.

C．Set your goal high!

D．After you have applied, go a step further and visit each school if you haven’t already done so.

E．Everyone hopes to go to their dream college.

F．Never lose heart even though you fail to be admitted to a college!

G．It may be quite a rough ride.

10 . Henry worked in a factory. He came from a poor family and was in school for only four years. He had to do the hard work, but he was paid less. He liked to watch football matches very much and spent much time on them.

One afternoon there was a big football match on the playground. He borrowed some money from his friend and hurried there. There were a lot of people there. And all the tickets were sold out. He was sorry for it. He saw a pole (杆子) outside the playground and climbed it quickly. A policeman came and said, “It is dangerous to stay on it! Come down!”

“Wait a minute, please!” Henry said and just at that moment the policeman heard cheers on the playground and asked in a hurry, “Which team has kicked a goal (进球)?” “Ours!” “Wonderful! You can stay there. But take care!” The policeman said happily and left. When the match would be soon over, he came back again and asked, “Who has won?” “Theirs, 3:2.” “Come down,” the policeman said angrily. “Such a match is not worth watching!”
