environment, when solar energy replaces or reduces the use of other energy sources

that have larger effects on the environment.

However,

use and settlement of these types of materials.

As with any type of power plant, large solar power plants can affect the

environment

near

their

locations.

The

placement

of

the

power

plant

may

have

long- term

effects on the habitats of native plants and animals. Some solar power plants may

require

water

for

cleaning

solar

collectors

and

concentrators

or

for

cooling

turbine

generators.

Using

large

volumes

of

ground

water

or

surface

water

in

some

dry

locations

may

affect

the

ecosystems

that

depend

on

these

water

resources.

In

addition,

the

beam

of concentrated sunlight a solar power

tower creates can kill birds and insects

that

fly into the beam.

The

amount

of

solar

energy

that

the

earth

receives

each

day

is

many

times

greater

than the total amount of all energy that people consume each day. However, on the

surface of the earth, solar energy is a variable and irregular energy source. The

amount of sunlight and the intensity of sunlight varies by time of day and location.

Weather and climate conditions affect the availability of sunlight daily and on a

seasonal

basis. The

type and

size of a

solar energy collection and conversion system

determines how much

of the available

solar energy we

can convert into useful

energy.

of the following best explains

A. Inexpensive B. dangerous C. Ineffective D. abnormal

influence can large solar power plants have on the locations?

A. Polluting the ground water.

B. Protecting the habitats of plants and animals.

C. Damaging the local natural balance.

D. Attracting birds and insects to the area.

does the last paragraph mainly tell us?

A. Different areas receive different amount of solar energy.

B. How to convert solar energy into useful energy.

C. The relationship between solar energy collection and the sunlight.

D. Some factors that influence the amount of solar energy collection.

B

It was rush hour on the morning of June 1 in the West Texas city of San Angelo.

Heather

Santellano,

36,

was

driving

her

white

2012

Mazda

on

Houston

、

Harte

Frontage

Road with her nine- year-old daughter and ten-year- old son in the back. Suddenly,

a

red

pickup

truck

cut

them

off.

Santellano

turned

the

wheel

hard

to

the

right,

sending

the Mazda skidding off the road and down an embankment(

堤

)that ended in a drop-off

after about 50 feet. If the car didn't stop, it would go airborne and plunge onto

the road some 20 feet below.

Then

a

bit

of

luck:

As

the

car

raced

toward

the

edge,

its

undercarriage

got

stuck

on the cement lip of the embankment ledge, stopping it cold. The occupants, however,

were far from safe. The car had come to rest on top of a retaining wall, literally

teetering(

摇摇欲坠

)on the edge of disaster. One sudden move by anyone inside could

send it over.

Jacob Rodriguez watched the scene unfold from the 'T'ruck Repair Plant where he

works.

Then

he

and

four

other

men

ran

to

the

car.

They

leaped

onto

the

trunk

to

balance

the weight as the terrified kids in the back seat watched.

Meanwhile, Julio Vasquez and his nephew, Marco Vasquez, were driving to their

jabs at nearby Premier Automotive. Julio jumped out of the car to help while Marco

went

to

the

shop,

grabbed

a

heavy-duty

stra p(

皮带

)

，

and

returned

to

the

swinging

car.

He fastened the Mazda to an P-350

truck that had been driven over by one of the other

rescuers. With the car secured, the group carefully opened the back

doors and helped

the children out.

But their departure shifted the car's weight, causing it to lean forward. The

men, still on-the trunk, asked Santellano to jump into the back seat to rebalance

the weight. She did and then inched out the back door. Finally, the men carefully

got off the trunk. Everyone was safe.

do we know about Heather Santellano?

A. She was a careless driver.

C. She ran into a pickup truck.

B. She drove her twins to school.

D.

She

made

Squirrels aren’t natural city dwellers(居民

). In 1986 the sight of one in

a tree near

New

York’s

city

hall so surprised passers

-by that a newspaper published

a report about the “unusual visitor”.

Around that time, the tree-

dwelling animals were being set free in America’s

urban areas to “create pockets of peace and calm like the countryside,” says

University of Pennsylvania historian Etienne Benson, who studied our relationship

to squirrels over the course of five years.

First, they were introduced to Philadelphia, then to New Haven, Boston, and New

York City. Park visitors were encouraged to feed them, and security guards ensured

their safety. In the 1910s a leader of the Boy Scouts of America(an organization

teaching boys practical skills)said that teaching children to feed squirrels could

show the rewards of treating a weaker creature with sympathy, says Benson.

By the early 20th century, though, America began to regret the friendliness it

had shown squirrels. Cities had once been filled with animals

—

from horses pulling

goods to dairy cows. By the 1950s those working animals had been moved to the

countryside.

Pets

and

wild

animals

such

as

birds

and

squirrels

were

all

that

remained

of the urban animal kingdom.

Before long, people’s enthusiasm for squirrels wore off, and they started to

see them

as

annoyances.

By the 1970s many parks

banned feeding the creatures. Today,

it is rare to find kids with their parents offering food to squirrels under a tree.

And,

unfortunately,

with

more

and

more

buildings

being

constructed

in

the

city,

fewer < /p>

inhabitable(

适宜栖息的

) areas are left for the little tree-dwelling animals.

What would be lost if the last of thes

e city dwellers were forced to leave? “I

“It’s

The

dangers

of

drowsy

（昏昏欲睡）

driving

have

been

widely

known.

Now

several

companies have developed face-tracking technology that can tell when drivers become

dangerously sleepy.

Here is how it might work. A camera in your car monitors your facial expression,

compares it to a database of expressions and determines if you are likely sleepy or

distracted. The car then alerts you to pay attention or pull over.

Affectiva has developed emotion recognition technology that aims to detect when

people are just starting to get tired. The idea is to catch the warning signs before

drowsiness really strikes. “Actually, when someone is

drowsy, that is too late.”

Gabi, vice president of Affectiva said. “What if you can see trends in someone’s
