     MIT researchers and their colleagues are working tofind out whether energy from trees
can power a network ofsensors(传感器)to prevent spreading forest fires.
     What they learn could also raise the possibility of usingtrees as silent guards along the
nation's borders to discoverpotential threatssuchassmuggled (走私的 ) radioactivematerials.
     The U. S. Forest Service currently predicts and tracksfires with a variety of tools,
including remotc automatcdweather stations. But these stations arc expcnsive andsparsely
(稀疏地) distributed. Additionalsensors could savetrees by providing better local climate
data to be used in fireprediction models and earlier warnings. However,rechargingor
replacing batteries by hand at very hard-to-reach locationsmakes it impractical and costly.
     The new sensor system seeks to avoid this problem bydeveloping trees into a
self-sustaining power supply. Eachsensor is equipped with a battery that can be slowly
recharged using electricity produced by the tree. "A singletree doesn't generate a lot of
power, but over time thetrickle (细流 ) chargeaddsup, justlike '-', saidShuguang Zhang,
one of the researchers on the project andthe associate director of the MIT' s Center for
Biomedica}Engineering( CBE). "
      The system produces enough electricity to allow the temperature and humidity sensors
to wirelessly send outsignals four times a day,or immediately if there's a fire.Each signal
spreads from one sensor to another, until itreaches an existing weather station that sends
the data bysatellite to a forestry command center in Boise,Idaho. Scientists have long
known that trees can produceextremely small amounts of electricity. But no one knew
exactly how the energy was produced or how to takeadvantage of the power.
1. What are the disadvantages of the remote automatedweather stations?
a. They cost too much.
b. They are of poor quality.
c. They are not enough.
d. They can't reach remote places.
A. a,b
B. b,d
C. a,c
D. b,c
2. Which of the following is the best sentence to fill in theblank?

A. Far water does not put out near fire.
B. All rivers run into sea.
C. Many a little makes a miracle.
D. It never rains but it pours.

3. What would be the best title for the passage?
A. Preventing forest fires with tree power
B. Trees can produce electricity
C. Tree power in daily life
D. Developing new energy

Lightning flashed through the darkness over Donald Lubeck’s bedroom skylight. The 80-year-old retired worker was shaken by a blast of thunder. It was 11 p.m. The storm had moved directly over his two-story wood home in the rural town of Belchertown, Massachusetts. Then he heard the smoke alarm beeping. Lubeck padded down the stairs barefoot and opened the door to the basement, and flames exploded out.

Lubeck fled back upstairs to call 911 from his bedroom, but the phone didn’t work. Lubeck realized he was trapped. “I started panicking,” he says.

His daughter and young granddaughters, who lived with him, were away for the night. No one will even know I’m home, he thought. His house was three miles off the main road and so well hidden by pines that Lubeck knew calling for help would be fruitless.

Up a hill about a third of a mile away lived Lubeck’s closest neighbors, Jeremie Wentworth and his wife. Wentworth had been lying down, listening to the radio when it occurred to him that the sound was more like a smoke detector. He jumped out of bed, grabbed a cordless phone and a flashlight, and headed down the hillside toward the noise.

He dialed 911. “Is anyone there?” he called out as he approached the house. Wentworth knew that Lubeck lived in the house.

Then he heard, “Help me! I’m trapped!” coming from the balcony off Lubeck’s bedroom.

“I ran in and yelled,‘Don, where are you?’ Then I had to run outside to catch my breath.”

After one more attempt inside the house, he gave up and circled around back. But there was no way to get to him. “I shined the flashlight into the woods next to an old shed and noticed a ladder,” says Wentworth. He dragged it over to the balcony and pulled Lubeck down just as the second floor of the house collapsed.

Wentworth and Lubeck don’t run into each other regularly, but Lubeck now knows that if he ever needs help, Wentworth will be there.

Lubeck still chokes up when he tells the story. “I was alone,” he says. “Then I heard the most beautiful sound in my life. It was Jeremie.”

1.According to the text, Lubeck___________.

A.stayed calm in the fire                    B.couldn’t find a safe way out

C.lived on the first floor                    D.called for help in the fire

2.How did Wentworth help Lubeck escape?

A.He called 911.

B.He went upstairs and took Lubeck out.

C.He put out the fire.

D.He used a ladder and pulled Lubeck down.

3.Which of the following factors was not mentioned in the text that almost cost Lubeck’s life?

A.He was living in his wood home alone that night.

B.The storm was too heavy and the fire was too fierce.

C.He lived far from the main road and was surrounded by pines.

D.He was too frightened to escape from the danger.

4.What does the text mainly talk about?

A.A near neighbour is better than a distant cousin.

B.A good way to get a narrow escape.

C.God helps those who help themselves.

D.Blood is thicker than water.
