1 . People who are overweight are often seen to have a strong desire for food at any time of the day. They keep on eating till they reach their satisfaction level. This often pushes them towards overeating.     1     Thus, if you are one of such people, you need to take steps to satisfy your hunger without overeating.

    2     This will give you a clear picture about the quantity of food you should eat at once. Do not overeat because you will have leftovers. You can always enjoy eating the leftovers at some other time and save time and effort required for cooking.

Do not rush while eating food. Take your time and eat slowly as this technique develops the feeling of fullness before your stomach is actually full.     3     This draws your mind’s attention towards your stomach, which will let you know whether your stomach is full or not.

Do not watch television while eating because it causes distractions.     4     Create a pleasant dining environment so that the satisfaction of having a great dining experience leaves your hunger satisfied without eating too much.

    5     Waiting for too long before eating will make you eat more. Drink a lot of water as it helps in reducing food desire without adding calories to the body.

A．Eat when you begin feeling hungry.

B．Overeating is a major cause behind poor health.

C．Start with the dish that seems more interesting to you.

D．Frequent overeating will result in unwanted weight gain.

E．Instead, sit at a dining table to concentrate on what you’re eating.

F．Decide how much you want to eat before actually eating your food.

G．To know if you are full during a meal, take deep breaths in between.

2 . Droughts(干旱)caused by global climate change have led to drop in wheat production, a worldwide shortage and high food prices around the world. The global wheat supply is at its lowest point in 50 years, with only an estimated 10 weeks of supply left. This has been one factor pushing the prices of bread, beer and other wheatcontaining foods steadily higher. According to Hilton Dinner, a bakery owner from Edmonton, Canada, the price of flour has more than doubled over the past eight months. In 19 years of business, Dinner said, he has never seen prices rise like this.

"Prices creep up seasonably," he said. "They might go up 10 percent, then down 5 percent. They never go back to where they started, but they creep. This is not creeping, this is drastic."

Also to blame for the global wheat shortage is the rising population, coupled with increasing meat consumption worldwide. This has led to the increasing diversion of grain to animal feed.

Analysts anticipate that the shortage may be resolved within 12 months, as farmers pull fallow land into wheat production. But even when the shortage resolves, food prices are only expected to keep climbing due to other factors, such as high energy and shipping costs.

"It's not something that's going to go away," Dinner said. "Food in general is going to go up. As wheat goes up, so does the price of eggs and chicken because they eat grainbased feed. It affects people who can't afford to pay more for their food."

Public health experts have expressed concern about the effect that rising food prices have on the poor. The United Nations recently reported that in 2007, the cost of food imports in the world's neediest countries increased 24 percent to a total of $107 billion.

1. The indirect reason for a drop in wheat production is ________.

A．the drought	B．the global climate change
C．the shipping cost	D．the rising population

2. According to the first paragraph, the prices of wheat products rise ________.

A．suddenly	B．gradually
C．slowly	D．rapidly

3. The wheat shortage may disappear if ________.

A．the empty lands are used to plant wheat

B．the shipping costs are falling down

C．chickens don't feed on wheat any more

D．beer isn't made from wheat any more

4. The passage mainly tells us that ________.

A．poor people can't afford food

B．the rising population leads to high food prices

C．the global climate change causes wheat shortage

D．food prices are going to go down

3 . Wildfires have captured headlines around the globe in recent years. These intense and widespread fires worry scientists. Besides causing billions of dollars in property damage, wildfires can erase the habitat of valued wildlife. They also fill the air with choking pollution. And when they burn near cities, they put the lives of whole communities in danger.

But scientists are interested in these fires for another reason. The black carbon-rich smoke from their flames is made of the ash from burned trees, grass and shrubs. The intense heat of some wildfires can cast this ash to high altitudes and it can travel around the globe.And the warming sunlight absorbed by dark particles(微粒)at high altitudes won't reach Earth's surface.

Scientists refer to those tiny particles of ash,dust and more as aerosols(气溶胶). One important trait is how well they reflect light. Snow and white ice reflect the most light. Dark things absorb the sun's light, mostly as heat. So the color of aerosols is important. Those aerosols can either warm or cool the air. Overall, researches showed that smoke aerosols cool the atmosphere. As intense fires cause dark ash aerosols high into the air, they mix with clouds and mostly prevent the sun's energy entering the earth.

The warming climate that can lead to wildfires may experience a temporary cooling when serious wildfires do erupt. Meanwhile, fire aerosols also can have bad effects when they fall back to Earth. And that fallout can sometimes be up to half a world away from where a fire took place.

Many studies show that intense wildfires are becoming more common, partly because of global warming. As the planet warms and new fires occur, scientists will continue to explore the big impact of tiny fire aerosols that temporarily occupy our atmosphere.

4 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

In an effort to fight against global warming, Purdue University engineers have created the whitest paint that can keep surfaces cooler than the formulation(配方)that the researchers had     1     (previous) shown.

The new whitest paint formulation reflects up to 98. 1% of sunlight compared with the 95. 5% of sunlight     2     (reflect) by the researchers' previous white paint and sends heat away from a surface at     3     same time.

Two features give the paint its extreme whiteness. One is the     4     (paint) high concentration of a special chemical,     5     is used to make photo paper white as well. And the second feature is that the barium sulfate particles(硫酸钡粒子) are all different     6     size in the paint. How much each particle scatters(散射) light     7     (depend) on its size, so a wider range of particle sizes allows the paint to scatter more of the light from the sun.

The extreme whiteness also means that the paint is the     8     (cool) on record. Using high-accuracy temperature reading equipment, the researchers have shown that the paint can keep surfaces 19℉ cooler than their surroundings at night and cool surfaces 8 ℉ below their surroundings under strong sunlight during noon hours, The researchers hold a firm     9     (believe) that coating buildings with this paint will one day cool them off enough     10    (reduce) the need for air conditioning.

5 . The urge for most of us is to throw something away, even if it means we have to buy anew one for more money.

6 . At any given moment, about seven microliters of tears are present in each of our eyes-about a tenth of a drop of water. Tears are more than salty water—they deliver oxygen and nutrients to our eyes, remove waste and serve as the first line of defense against disease.

Research has shown that markers of many of the most common diseases like cancer are found in tears. Work is already under way to confirm the use of such markers for diagnosing Alzheimer's disease. Recently, a technology named TearExo has been developed for breast cancer screening using patients' tears. That could greatly reduce the costs of testing.

Actually, the potential merits of tears as indicators of health go beyond occasional testing. One promising tear-based technology is a smart contact lens that continuously monitors a patient's biomarkers, significantly improving disease prevention and early detection. Recently, a smart contact lens has been successfully developed for continuous glucose monitoring and treatment of diabetic retinopathy. Such a product probably won't be ready for commercial use for several years. However, about 45 million people in the US already wear contact lenses to correct their vision, so switching to a smart version will be simple for them.

Interestingly, NASA ever suggested using tear markers to monitor astronauts' health in space. This allowed us to better understand the effects on human health of long-term exposure to space environmental factors like weightlessness. Tear markers from experienced astronauts and new astronauts without space exposure could be used to establish a health database, which might be one of the first stepping stones toward making living in space a reality.

Tears can provide an inexpensive, rapid and easy-to-use alternative to monitor health. Given the advantage in tear technology to monitor health, and to be used even by the healthy, such technology will almost certainly lead to the more effective prevention of diseases—rather than having to deal with the difficulties of treating them.

1. How does the author show the use of tears in testing?

A．By listing data.	B．By using remarks.
C．By giving examples.	D．By making comparisons.

2. What does the underlined word "merits" in paragraph 3 probably mean?

A．Limitations.

B．Amounts.

C．Expenses.

D．Advantages.

3. What can we know about the tear-based contact lens?

A．It can hardly correct our vision.	B．It helps to detect diseases continuously.
C．It has been used commercially.	D．It can successfully cure eye illnesses.

4. What does the author think of tear technology?

A．It serves as a basis for space exposure.	B．It can free astronauts of weightlessness.
C．It monitors health effectively but slowly.	D．It has a bright future in the medical field.

7 . “My mom found a house for us to look at.” said my fiancé (未婚夫), Jon. “It’s in Richfield, not far from where I grew up.”

“Wow, that’s great!” I said. “Maybe this will be the one.”

Jon and I had been searching for our first home for months. Nothing seemed right. The listings in Richfield had been off the mark. But if my soon-to-be mother-in-law, Ruthann, had come across a house for us to look at. I was going to check it out.

I hadn’t known much about Ruthann. Her beloved grandmother, Nana, had recently passed away, and she was in grief(悲痛). Nana had been the heart of the family, and Ruthann had been especially close to her. I regretted not getting to meet Nana. I felt I was struggling to find my footing with my future in-laws. So, I would do whatever I could to draw us closer.

The next day, Jon and I drove over for the viewing. I was pleasantly surprised–the house Ruthann picked looked fantastic. My hopes rose as Jon and I walked into the dining room, which had an ivy(常春藤)wallpaper border, It perfectly matched the pretty set of ivy plates I’d been storing away. I knew we found our home.

We bought the house and got married. When it was time to move. both of our families helped out. I set a few things on the shelves in the dining room, leaving a large space in the center for my ivy plates. Ruthann walked in as I was carefully lifting the plates out.

“Where did you get those?” she asked.

“I bought them a long time ago,” I said proudly, happy that my mother-in-law seemed to like them.

Ruthann sat down, shaking her head in disbelief. “Sandy, you don’t understand…Those dishes have the same pattern as the dishes Nana had in her house. So many family gatherings and special occasions happened with those plates…” she smiled. “We sold them along with the other items in the house. Now here you are, with a matching set you bought years ago…”

I suddenly realized I needn’t have worried about fitting in with Jon’s family.

8 . Having trouble getting to sleep these days? Here are a few habits that can really help.

Open the blinds and go outside

Open the blinds to start your day with a sunlight bath in the early morning. If you can, go outside for at least 20 minutes in the midmorning hours.     1    .

Move your body and get tired

As hard as it may be to fit a workout routine into your day, it's worth it. Regular exercise may help promote good sleep in two ways. Physical activity is known to reduce mental anxiety. This alone may contribute to good sleep.     2    . So it can help you fall asleep faster. However, don't exercise too close to bedtime. Otherwise, you may get over-excited and cannot fall asleep.

    3    

Your core body temperature needs to drop by about2 to3 ℉ to get a good sleep. A study suggests it is important to keep your bedroom around 65 ℉ all the night.

Don't count sheep

Not only will counting sheep not help you fall asleep faster, but a study by Allison Harvey at UC Berkeley also has found that it actually makes it harder to fall asleep. Harvey has found that other types of mental games, however, are helpful to sleep.     4    , like a hike in the woods or a walk down on a beach that you have done on vacation.

Use your bed only for seep

Lying awake in bed can lead to worry about sleep, which makes falling asleep even harder. To avoid this cycle, you might need to spend less time in bed. It seems unbelievable. But it is true.     5    .

A．Do what works for you

B．Keep your bedroom cool

C．So try to read a very boring book in your bed

D．In addition, regular exercise can physically tire you out

E．He suggests imagining pleasant walks you've taken before

F．Therefore, if you're not going to see, you'd better get out of bed

G．Studies show that daylight bath in the morning leads to better sleep at night

9 . Throughout history, there have been sculptors who are prized for their willingness to push boundaries. Without their contributions, it would be difficult to imagine visual art as we now know it. Here are some of the pioneers.

Gianlorenzo Bernini (1598~1680)

As a master of materials, Italian artist Gianlorenzo Bernini is known for his astonishing ability to create movement and bring forth emotion with his work. In his masterpiece, Pluto and Perse, the rough and cold stone has been turned into flesh that looks so real and soft that you just want to reach out and touch it.

Alberto Giacometti (1901~1966)

Swiss sculptor Alberto Giacometti is perhaps most recognized for his slim and small sculptures, like Seated Man, with each piece measuring no more than 2.75 inches in height. Many scholars have suggested that his slim figures relate to a lack of meaning in 20th-century life.

Henry Moore (1898 ~ 1986)

Known for his abstract public sculpture, British artist Henry More's works most often focus on the theme of mother and child, who usually sit or lie in a relaxed way, with their bodies leaning backwards Moore's figures are often composed of multiple pieces, yet his clean lines allow viewers to effectively see the figures within the abstract form. Such features are very obvious in his master piece Mother and Child.

Louise Bourgeois (1911 ~ 2010)

Most well-known for her public art, French-American sculptor Louise Bourgeois rose to international lame in 1982 after the Museum of Modern Art held her first exhibit. By this time, she was already in her 70s. Drawing from her own life experience, her sculptures often explore themes of family and death. In her representative work, Maman, Bourgeois has used a spider to stand for her mother, who died when she was a child, to show her strength and protection over her family.

1. When did Alberto Giacometti pass away?

A．In 1689.

B．In 1966.

C．In 1986.

D．In 2010.

2. Which one belongs to realistic sculpture?

A．Maman.

B．Mother and Child.

C．Seated Man.

D．Pluto and Persephone.

3. What do the last two artists have in common?

A．They became famous in their 70s.	B．They are known for their public sculptures.
C．They are from the same country.	D．They explored the themes of family and death.

“Father of hybrid rice”, Yuan Longping died of illness at 13:07 p.m. in     1     hospital in Changsha of Hunan province.

He     2     (cultivate) the world's first high-yielding hybrid rice strain in 1973,     3     was later grown on a large scale in China and other countries to substantially raise output. Yuan once said he had two dreams — to “enjoy the cool under the rice crops taller than men” and that hybrid rice could     4     (grow) all over the world     5     (help) solve the global food scarcity(短缺). Everyone knows that he is the Savior(救世主),     6     he said he is an old farmer who has grown rice all     7     life, and he would keep working unless he could no longer see or walk.

On September 19, 2020, Yuan Longping sent his best wishes to the youth and shared his eight word     8     (success) experience: knowledge, sweat, and opportunity. “Knowledge is the foundation. Sweat is the practice,” he said. “Inspiration is a spark of thought. Everyone has a spark of thought so don't give it up.” He also said “Chance favors the     9     (prepare) mind!” in English.

Our best way    10     (mourn) is to cherish every grain in the bowl and every day without starvation.
