Have you ever spent an afternoon in the backy...

Have you ever spent an afternoon in the backyard, maybe grilling or enjoying a basketball game, when suddenly you notice that everything goes quiet? There is an old phrase “calm before the storm”， often used in a situation—a quiet period just before a great activity or excitement. According to our own experience, we know there is actually calm before the storm. But what causes this calm? And is it always calm before the storm? Let's hear what scientists have to say.

A period of calm happens in a particular kind of storm, the simplest kind of storm—a single－cell thunderstorm. In this type of thunderstorm, there is usually only one main updraft, which is warm, damp air and drawn from places near the ground. Storms need warm and damp air as fuel, so they typically draw that air in from surrounding environment. Storms can draw in the air that fit their need from all directions—even from the direction in which the storm is traveling.

As the warm, damp air is pulled into a storm system, it leaves a low－pressure vacuum(真空) coming after. The rising air meets the cold dry air that has already existed in the storm clouds, thus the temperature of the warm, damp air drops, and the water vapour(水蒸汽) in it changes into tiny drops that are a precondition of rain. These drops accumulate and build on larger particles like dust, until they grow large enough to form raindrops.

This warm, damp air keeps moving upwards, but it becomes cooler and drier during its trip through cloud. When it reaches the top of the cloud, the air gets spit out(被挤出) at the top. This air is sent rolling out over the big thunderclouds. From there, the air goes down. Warm and dry air is relatively stable, and once it covers a region, that air, in turn, causes the calm before a storm.

Most thunderstorms, though, don't start with calm. That's because most are actually groups of storms with complex wind patterns. There's so much air moving up and down storm groups that the calm before the storm never happens. Instead, before the storm, it might be really windy!

1.Which best fits the description of a particular kind of storm?

A. A storm with air drawn from every direction.

B. A thunderstorm without strong winds.

C. A thunderstorm with a single shape.

D. A storm fueled by moving air from the ground.

2.What does the underlined word “it” in Paragraph 3 refer to?

A. Cold and dry air. B. Warm and damp air.

C. Cold and damp air. D. Warm and dry air.

3.Which does the writer most likely agree to?

A. Presence of the calm relies on stable air.

B. Storm happens without air moving up and down.

C. The drier the air is, the bigger the storm will be.

D. Not all thunderstorms start with the calm.

4.What is the passage mainly about?

A. Causes and effects of a heavy storm.

B. An explanation of the calm before a storm.

C. A personal experience of a heavy storm.

D. A brief description of a peaceful storm.

A period of calm happens in a particular kind of storm, the simplest kind of storm---a single-cell thunderstorm. In this type of thunderstorm, there is usually only one main stream of current, which is warm, damp air and drawn from places near the ground. Storms need warm and damp air as fuel, so they typically draw that air in from surrounding environment. Storms can draw in the air that fit their need from all directions—even from the direction in which the storm is traveling.

As the warm, damp air is pulled into a storm system, it leaves a low-pressure vacuum(真空) coming after. The rising air meets the cold dry air that has already existed in the storm clouds, thus the temperature of the warm, damp air drops, and the water vapor in it changes into tiny drops that are a precondition of rain. These drops accumulate and build on larger particles(颗粒) like dust, until they grow large enough to form raindrops.

This warm, damp air keeps moving upwards, but it becomes cooler and drier during its trip through cloud. When it reaches the top of the cloud, the air is squeezed out at the top. This air is sent rolling out over the big thunderclouds. From there, the air goes down. Warm and dry air is relatively stable, and once it covers a region, that air, in turn, causes the calm before a storm.

Have you heard of the following people? Maybe yes, maybe no. But they may be an inspiration for you.

The Tree Lady

Kate Sessions was an American botanist and landscape architect closely associated with San Diego, California. After becoming the first woman to graduate from the University of California, Berkeley, she took a job as a teacher far south in the dry desert town of San Diego. Kate decided that San Diego needed trees more than anything else. Therefore, this young woman single-handedly started a movement transforming the town into the leafy, garden-filled place as it is today.

The Snowflake(雪花) Man

Wilson Bentley is one of the first known photographers of snowflakes. His enthusiasm for taking photos began from his boyhood and was often misunderstood in his time, but his determination revealed two important truths: no two snowflakes are alike; and each is surprisingly beautiful. In 1931, he worked with William J.Humphreys of the U.S. Weather Bureau to publish Snow Crystals, a book containing 2500 photographs.

The Father of His Country

By the late 1760s, George Washington had experienced firsthand the effects of rising taxes imposed (征收) on American colonists by the British, and came to believe that it was in the best interests of the colonists to declare independence from England. During the American War of Independence, he led the colonial forces to victory. In 1878, he was elected president of the Convention that wrote the U.S. Constitution. Two years later, Washington became American’s first president. His retirement from office after two terms established a tradition that lasted until 1940, when Franklin Delano Roosevelt won a third term. The 22nd Amendment (1951) now limits the president to two elected terms.

Have you ever thought of quitting your job when you feel exhausted? Maybe most of you would say “yes”. After a particularly busy period at work, I decided to get away from it all by going on a hike in the mountains in southern France.

Before I left, I read an interesting story in a magazine. It read, “Once, while I was riding on a crowded bus, the man sitting next to me threw his cell phone out of the window when his phone rang. I was surprised. He looked at me, shrugged (耸耸肩) and looked away. I had no idea whether it was his or stolen or whether he even knew what a cell phone was or not, but he clearly wanted to be free of it, because it clearly troubled him.”

Billions of people across the world use cell phones. Though cell phones are a wonderful way for communication, they often do the exact opposite. Using cell phones can increase stress within families and friends.

So when I recently returned home, I got rid of my cell phone. Now I go outside without taking my phone with me. I’ve noticed things in my neighborhood I never noticed before, such as gardens. I’ve met new people, started conversations with neighbors I didn’t speak to before and talked with some of my friends face to face instead of chatting over the phone.

Instead of keeping me off from the world, stopping using my cell phone has helped me get even closer to my family and friends.

Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.

Some scientists believe that birds do sing some of the time just because they are happy. However they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.

Do you know what a ‘territory’ is? A territory is an area that an animal, usually the male, claims as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.

If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting（筑巢）season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.

Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.

You can see that birds have a language of their own. Most of it has to do with attracting mates and setting up territories.

1.Some scientists believe that most of the time bird’s singing is actually________.

A. an expression of happiness    B. a way of warning

C. an expression of anger        D. a way of greeting

2.What does the underlined word “territory’’ mean?

A. A place where families of other species are not accepted

B. A place where a bird may shout at the top of its voice

C. An area for which birds fight against each other

D. An area which a bird considers to be its own

3.Why do birds keep on singing at nesting season?

A. Because they want to invite more friends

B. Because their singing helps frighten outsiders away

C. Because they want to find outsiders around

D. Because their singing helps get rid of their fears

4.How does the writer explain bird’s singing?

A. By comparing birds with human beings

B. By reporting experiment results

C. By describing birds’ daily life

D. By telling a bird’s story
