Passage 1

In the United States, 30 percent of the adult popul

ation has a “weight problem”.

To

many

people,

the

cause

is

obvious:

they

eat

too

much.

But

scientific

evidence

does little to support this idea. Going back to the America of the 1910s, we find that

people

were

thinner

than

today,

yet

they

ate

more

food.

In

those

days

people

worked harder physically, walked more, used machines much less and didn’t watch

television.

Several

modern

studies,

moreover,

have

shown

that

fatter

people

do

not

eat

more on the average than thinner people. In fact, some investigations, such as the

1979 study of 3,545 London office workers, report that, on balance, fat people eat

less

than

slimmer

people.

Studies

show

that

slim

people

are

more

active

than

fat

people. A study by a research group at Stanford University School of Medicine found

the following interesting facts: The more the men ran, the more body fat they lost.

Quiz 1

Quiz

The

more

they ran,

the greater

amount

of food they ate.

Thus,

those

who

ran the

most ate the most, yet lost the greatest amount of body fat. (183 words)

6.

The

physical

problem

that

many

adult

Americans

have

is

that

____C_________.

A. they are too slim

B. they work too hard

C. they are too fat

D. they lose too much body fat

7. According to the article, given 500 adult Americans, ______A___people will

have a “weight problem?”

A.

30

B.

50

C.

100

D.150

8. Is there any scientific evidence to support that eating too much is the cause

of a “weight problem?”

B

A. Yes, there is plenty of evidence.

B. Of course, there is some evidence to show this is true.

C. There is hardly any scientific evidence to support this.

D. We don’t know because the information is not given.

9. In comparison with the adult American population today, the Americans of

the 1910s_______A___.

A. ate more food and had more physical activities

B. ate less food but had more activities

C. ate less food and had less physical exercise

D. had more weight problems

Passage 2

Popeye

the

Sailor

(

大力水手

)

first

became

a

popular

cartoon

in

the

1930s.

The

sailor

in that

carton

ate

lots of

spinach

(

菠菜

)

to

make him

strong.

People

watched him, and they began to buy and eat a lot more spinach. Popeye helped

sell

33 percent

more

spinach

than

before!

Spinach

became

a

necessary

part of

many people’s diets. Even some children who hated the taste began to eat the

vegetable.

Many people thought that the iron in spinach made Popeye strong, but this is

not true. Spinach does not have any more iron than any other green vegetable.

People only thought spinach had a lot of iron because the people who studied

the food made a mistake. In the 1890s, a group of people studied what was inside

vegetables. This group said that spinach had ten times more iron than it did. The

group wrote the number wrong, and everyone accepted it.

Today,

we

know

that

the

little

iron

there

is

in

spinach

cannot

make

a

difference in how strong a person is. However, spinach does have something else

which the body needs

–

folic acid (

叶酸，维生素

B). (203 words)
