For the brave in the armed forces, being sent away from home for months at a time is just part of the duty. However, it’s

never an easy one to perform especially for those with children. So when I found out I was going to be stationed in South Korea

for a year, I was nervous about how my five children, particularly my eldest daughter Abigail, would take the news since it

meant I wouldn’t be home to see her graduate from high school.

Incredibly, Abigail told me

not to worry and even suggested we

live stream

the event among family

members

when I

leaked the news. “We’ve been lucky you haven’t had to be sent abroad yet. Anyway we can get connected through the Internet.

See me on your phone on my spot. ” Abigail said. She stepped into many of my roles when I wa

s gone. I wanted to find a way

to thank her and show her how proud I was of her. I started planning the special surprise when my request to return home a few

weeks early to attend Abigail’s graduation ceremony was approved.

When my time in South Korea fina

lly came to an end, I flew home, rented a car, and stayed in a hotel. And on Abigail’s

graduation day, I hid in an office behind the stage waiting until I heard my daughter’s name called. I just kept thinking “Don’t

cry. Don’t trip in your heels. Don’t fall over.” At last! Abigail was up on stage. I slipped up behind her, whispered in her ear,

and

around

she

turned!

“I

was

just

thinking,

like,

‘You

aren’t

supposed

to

be here.

What?

What?

How?’

It

was

the

biggest

shock..

. I’m pretty sure my dad made people he didn’t even know cry. Emotional for everyone,” Abigail cried.

You know what followed:

Embraces, kisses, tears, laughs, flowers, wishes... aren’t they what a family have in store?

C. The meaning of family bond.

D. The way to plan a big surprise.

Food blogs, celebrities, and nutritionists all advocate the benefits of eating organic (

有机的

) fruits and vegetables. But a

new study published in Science Advances paints a more complex picture. While organic produce is likely slightly healthier to

eat and, in some ways, more sustainable to grow, there are also

downsides

.

Organic

fruits

and

vegetables

typically

cost

more

than

conventional

ones.

To

get

a

certificate

as

organic,

farmers

must

meet specific criteria, including growing produce without the use of genetic engineering and chemical inputs. Without these

methods, the growing process typically requires more labor, time, and money, a cost that is passed down to consumers.

It’s true that in many ways, organic is more sustainable than conventional farming. But when it comes to environmental

concerns such as greenhouse gas output and water loss, the comparison gets complex. Organic farms produce less gas output

per

acreage. However,

because

they

are

barred

from

using

genetic

engineering,

pesticides

(

杀虫剂

),

and

other methods

that

increase

efficiency

(

效率

),

organic

farms

also

produce

an

estimated

19%

to

25%

less

yield

than

conventional

farms.

While

there isn’t a whole lot research on the topic, the few studies that do exist suggest green gas output and water loss might ac

tually

be higher on organic farms, on a per unit basis, says study author Verena Seurfert.

In

addition,

while

organic

produce

is

likely

more

nutritious

than

conventional

fruit

and

vegetables,

there’s

not

a

lot

of

evidence

to

support

the

claim

that

these

often

slight

differences

influence

consumer

health.

The

same

is

true

for

pesticide

remainder. In developed countries, where pesticide use is tightly regulated, there’s no scientific consensus on how these oft

en

slight differences influence human health.

Still,

Seurfert

stresses

that

if

you

can

afford

to

eat

organic,

you

should

do

so.

Organic

farms

provide

safer

work

environments for workers, plus they support great biodiversity. The real takeaway from her study is not that organic is bad but

that the practice needs more study to increase yield without lowering sustainability.

But if you can’t afford to buy organic produce, don’t stress too much, particularly from a nutritional perspective.

28. What does the underlined word “

downsides

” in Paragraph 1 most probably mean?

A. Dangers.

B. Drawbacks.

C. Benefits.

D. Differences.

29.

Which

key

factor

makes

it

hard

to

compare

organic

farming

and

conventional

farming

when

it

comes

to

environmental

concerns?

A. The yield.

B. The price.

C. The water loss.

D. The labor.

30. Which of the following will the author most probably agree with?

A. Farmers, work environment should be improved.

B. Organic produce should be made more efficiently.

C. It isn’t wise for consumers to buy organic products.

D. Pesticide remainder does no harm to people’s heal

th.

31. In the author, s opinion, why should we support organic produce?

A. It’s environmentally friendly.

B. It’s more nutritious.

C. It helps keep the variety of plants.

D. It’s safer for consumers.

Every

ocean

lover

knows

the

dangers

of

getting

caught

in

a

rip

current

(

离岸流

).

Experienced

swimmers

know

it

is

relatively easy to escape the narrow channel of the fast moving water by floating and allowing it to drag you further into the

ocean or by swimming alongside the shore. However, inexperienced beachgoers often panic, and try to swim to land, placing

themselves

at

risk

of

drowning

due

to

tiredness.

According

to

the

US

National

Ocean

Service,

the

currents

kill

about

100

Americans each year and account for 80% of all lifeguard rescues. These scary statistics may soon be a thing of the past, thanks

to Clever Girl, a smart buoy (

浮标

) that warns swimmers of the presence of deadly rip currents.

The smart device is the brainchild of Australian teenager Maddison King, who created Clever Girl as a project for her

Grade 12 Design and Technology class. The 18-year-old, who works as a lifeguard during her spare time, came up with the

brilliant idea after discovering that most children were unable to detect rip currents.

The basketball- sized plastic buoy, which can be attached to a chain of similar devices or the ocean floor, is fitted with a

small propeller (

螺旋桨

). When the water travels at speeds of over 70 centimeters per second, it spins the propeller fast enough

to power the light atop the buoy, warning swimmers to stay clear of the area.

Though it sounds simple enough, the youngster had to overcome numerous design challenges. For instance, she picked a

red light since it is easy to see in the bright sunlight and also because the color serves as a universal warning sign for tourists

that do not speak the local language. The device’s smooth surface and high h

andles ensure swimmers do not get hurt, while the

black, white, and red striped underside, keeps sharks and other animals at bay.

Future

versions

might

include

something

like

a

warning

siren,

which

would

provide

sound

warnings

of

rip

currents.

Besides, the

present model cost about $$ 300 to make. “That’s beyond my purse.” she laughs, “the cost has to be cut down.”

32. Which of the following is the right way to escape the rip current?

A. Waiting for rescues.

B. Swimming to the shore.

C. Moving fast in the water.

D. Floating with the water.

33. Why did Maddison decide to invent Clever Girl?

A. She wanted to challenge her creativity.

B. She was motivated by her working experience.

C. She was supposed to complete it for her class.

D. She was scared by the statistics of the government.

34. What do we know about the present version of Clever Girl?

A. It’s not available on the market.

B. It’s quite attractive for sea animals.
