The Great Barn Adventure

One morning when I was 11，I explored the town's abandoned round grain barn (谷仓)．I found a chained sliding door that was wide enough for me to pass through.

Inside，there was a heavy smell of dead mice in the dark.After my eyes adjusted，I noticed a shaft (竖井) that rose all the way to the top of the barn.On one side was a one­man elevator with a long rope and roller.

I stepped onto the platform and gave the rope a drag and the elevator began sliding up the shaft，but stopped halfway.After a brief panic attack，I noticed holes in the wall at regular intervals，forming a ladder.For reasons known only to all 11­year­old，I decided it would be better to go up than down.So，with shaking hands，I began climbing the wall.

After what seemed like forever，I reached the top of the shaft.I stood up，dusted myself off and found...absolutely nothing of interest.It was just an empty room with a ladder leading up to the roof.I climbed all the way up here for this? Then I noticed a fire extinguisher (灭火器)，which I'd always wanted to shoot off.So this was the chance of a lifetime.I tried it，and，much to my surprise，the thing worked! It shot out a thick cloud of powder that instantly filled the room.I couldn't breathe.I was going to choke to death，and they'd probably never even find my body.

Luckily，I remembered the ladder to the roof.I climbed up，popped the straw roof and saw a bright blue sky.

I suddenly realised the dust and powder pouring out of the top could draw attention.So when the dust had settled，I climbed down and slipped out of the chained door.I'm not sure if I was more excited about being alive or about not being caught，but I ran all the way back home.

【语篇解读】　这是一篇记叙文，讲述了作者11岁时到废弃谷仓捣蛋的经历。

1．When the author got inside the barn，he         ．

A．noticed a man on the elevator

B．opened the chained sliding door

C．saw many dead mice in the dark

D．found a shaft leading to the top

D　[细节理解题。根据第二段中“...was a one­man elevator”可知A项错误；根据第一段中“...found a chained sliding door...”可知是发现了而不是打开了门，故B项也排除；再根据第二段中“...there was a heavy smell of dead mice in the dark.”可知，有死老鼠的气味而不是看到死老鼠，故C项应排除；D项意为“有个竖井能直通仓顶”，符合文意。]

2．Which of the following is the right order of the author's adventure?

a．The elevator stopped halfway.

b．He entered the round grain barn.

c．He climbed to the top of the shaft.

d．He found a fire extinguisher and shot it off.

A．b－a－c－d B．a－c－b－d

C．c－a－d－b D．b－c－a－d

A　[细节理解题。根据文章的叙述可知，作者首先是进了谷仓(b)，然后想坐电梯到仓顶去，结果升了一半就停了(a)，于是作者爬到竖井顶端(c)，在上面看到一个灭火器并淘气地打开了灭火器(d)，因此A项正确。]

3．After getting out of the chained door，the author might feel         ．

A．inspired  B．relieved

C．surprised 　 D．disappointed

B　[推理判断题。作者在谷仓屋顶找到了一个灭火器并且打开之后，灭火器浓浓的粉末让作者几乎窒息，跑出来的过程中掀起的灰尘以及浓浓的粉末让他担心会引起人们的注意，因此在跑出来之后觉得庆幸，他不知道是庆幸死里逃生还是庆幸没被人发觉，由此推断作者跑出来后应是感觉如释重负(relieved)。]

4．From the passage，we can learn that the author was probably a boy full of         ．

A．passions 　 B．dreams

C．curiosity 　 D．imagination

C　[推理判断题。从文章的标题及描述内容可以推断出，作者那时是个很好奇的男孩。故C项符合文意。]

B

Dust storms don't just happen in the middle of the desert.They happen in any dry area where loose dirt can easily be picked up.The sand blown into the air by the wind usually falls back down to the ground after a few hours.Smaller bits of particles (微粒) stay in the air for a week or longer and can be blown thousands of miles away.Dust from the Sahara is always blown across the Atlantic and keeps travelling as far as Caribbean.

The scary thing about sandstorm is that they can spread over hundreds of miles and rise over 10，000 feet (3050 meters)．They also have wind speeds of at least 25 miles per hour (40km)．Not strong enough to blow the feathers off a chicken but still something worth avoiding.

Don't be surprised if you suddenly see a dust storm heading your way.Dust storms usually arrive without warning and move in the form of a big wall of dust.The dust makes driving impossible.Often they only last for a few minutes but storms usually leave serious car accidents behind.If you are in a car during a dust storm，remind the driver to pull over and turn off the headlights.

In mild (轻微的) dust storms，it's still impossible to walk around although you wouldn't want to.You can't see anything because of the dust particles flying around.It's not just the dust you want to avoid.The wind carrying the dust will leave things as if they were just hit by a tornado.The best thing to do is find a safe place in a building.

【语篇解读】　文章的主要内容是讲述了沙尘暴的一些性质，以及遇到沙尘暴时的应对措施。

5．What can we know from Paragraph 1?

A．Sand blown into the air can float for months.

B．Dust storms don't happen in the heart of the desert.

C．Dust blown into the air can travel a very long distance.

D．Smaller bits of particles stay in the air for only a few hours

C　[推理判断题。根据第一段的“Smaller bits of particles (微粒) stay in the air for a week or longer and can be blown thousands of miles away.”可知，较小的粒子在空中待了一个星期或更长时间，然后可以被吹到数千英里之外。故可推知C项正确。]

6．What does Paragraph 2 mainly talk about?

A．The speed of the wind.

B．The harm of dust storms.

C．The movement of dust.

D．The power of dust storms.

D　[主旨大意题。根据第二段的主要内容可知，沙尘暴的可怕之处在于，它可以蔓延数百英里，上升到1万英尺(3050米)以上。故可知本段主要讲述的是沙尘暴的威力，此题易误选A项，但A项说的是“风的速度”，而不是“沙尘暴的速度”，故选择D。]

7．What should a driver do when he is caught in a dust storm?

A．Stop by the roadside.

B．Slow down a little bit.

C．Turn on the headlights.

D．Drive along the side of the road.

A　[细节理解题。根据第三段的“If you are in a car during a dust storm，remind the driver to pull over and turn off the headlights.”可知如果你在沙尘暴中开车，提醒司机靠边停车并关掉前灯。故A项正确。]

8．Which of the following statement is TRUE when the dust storm is not strong?

A．You should find a safe shelter.

B．You can walk around as usual.

C．There is no need to avoid dust.

D．People can see everything clearly.

A　[细节理解题。根据最后一段“In mild (轻微的) dust storms，...The best thing to do is find a safe place in a building.”可知沙尘暴没那么强时，最好的办法是在建筑物里找一个安全的地方。故选择A项。]
