A

college

education

is

an

But

it

can

be

a

47

one.

The

College

Board

48

that the costs at a four-year public college in the United States increased 10% this past school year.

All fifty states and the District of Columbia

51

what are called 5-29 plans. These plans are named after

the part of the federal tax law that created them in 1996. States use private investment companies to operate the

52

of the programs.

Every state has its own rules

53

5-29 plans. Some of the plans are

54

of state taxes. And all are

not required to pay federal taxes. However, the government could start to tax withdrawals in 2011 if Congress

There

is

progress

toward

a

possible

treatment

for

lung

diseases

such

as

SARS

(severe

acute

respiratory

syndrome).

Researchers

have

learned

more

about how

the

SARS

virus

works:

it

47

with a

system

in

the

body

that

uses

enzymes

(

酶

)

to

control

blood

pressure

and

fluid

balance.

Scientists

say

the

virus

48

to

an

enzyme known as ACE-two. The virus blocks the enzyme, permitting fluid to enter the lungs.

A

team

from

Europe

and

Asia

reported

the

49

in

Nature

Medicine.

Doctor

Josef

Penninger

of

the

Institute of Molecular Biotechnology in the Austrian Academy of Sciences was the

50

writer of the report.

The discovery could lead to a new

51

of treating not just SARS but also other diseases that can cause lung

failure. These include avian flu (

禽流感

) and influenza in humans.

The first

52

of SARS were discovered in Guangdong province, in southern China, in November of

2002. SARS was not

53

as a worldwide threat until March of 2003. The disease spread to 26 countries, most

of them in the Asia-Pacific area. An estimated 8, 000 people had SARS. More than 770 of them died, or about

10% , a

54

high rate.

The

World

Health

Organization

warned

people

not

to

travel

to

55

areas.

To call something

“

marginal

”

means it is not very good. Farmers have their own way to

47

marginal

land: It is the last to be planted under good conditions, and has the

48

to be avoided under poor conditions.

Low

49

soil is not the only reason land could be considered marginal. It might be in an area where rainfall is

50

or where a hillside might rise too steeply.

There are uses for marginal land, however. Most often it is used as grassland.

Grasses provide excellent

51

for grazing (

吃草

) animals like cattle, sheep and goats.

Grass seed can be bought from a foreign supplier or

52

grasses

can

be

used.

However,

using

marginal

land

for

grazing

is

not

a

simple

issue.

There

is

a

53

of

overgrazing. Cattle can damage the crops by eating down to the roots. Also, the weight of the animals crushes the

soil and can make it too hard for growing. A(n)

54

way to reduce the harm is to move animals from one field

to

another.

This

method

is

known

as

rotational

grazing

(

循环放牧

)

which

is

extremely

important

for

marginal

land.

Another use for marginal land is for tree crops. Studies have

55

that the white pine and loblolly pine

(

火炬松

)

are

two

kinds

of

trees

that

grow

well

on

such

land.

They

grow

fast

and

provide

good

quality

wood.

Another tree is the poplar (

白杨

), found in many parts of the world.

Failure

to

take

the

care

needed

to

protect

marginal

lands

can

make

a

bad

situation

worse.

But

good

planning can

56

a marginal resource into a highly productive one.

A) feed

F) define

K) native

B) priority

G) adequate

L) revealed

C) transplant

H) transform

M) prejudice

D) effective

I) discouraging

N) hazard

E) limited

J ) quality

O) recovered
