When Elon Musk says, as he did this week, that his new priority is using artificial intelligence to

build domestic robots, we should not only take note, but look forward to the day we can put our

legs up in admiration.

Mr. Musk is a guy who gets things done. The fo

under of two “moonshot” tech companies, Tesla

Motors and SpaceX, is bringing electric vehicles to mass market and 26 humans to live on other

planets.

Lest

this

strike

the

amateur

techie

—

not

that

readers

of

The

Independent

would

ever

count among them

—

as so much hot air, you can be reassured that the near $$13bn (

￡

fortune

this entrepreneur has 27 comes from practical achievements rather than hypothetical ones.

A

lot

of

people

are

28

about

artificial

intelligence,

fearing

that

robots

will

one

day

beco

me so 29 they’ll murder all of us. These fears are mostly 30 : as with hysteria about genetic

modification, we humans are generally wise enough to manage these problems with alacrity and

care.

And just think of how wonderful it would be if you had a live-in robot. It could

—

31

—

be like

having a babysitter and masseuse rolled into one

—

or, if that required 32 intelligence beyond the

ken of Mr. Musk’s imagined machine, at least some one to chop the carrots, wash the car and

mow the lawn. Once purchased and trained, this would allow the 33 user to save money and time,

freeing up 34 space in our busy lives to, for instance, read The Independent.

That is why we welcome Mr. Musk’s latest 35 , and wish him well. As long as robots add to the

sum

of

human

happiness,

suffering

cumbersome

activity,

and

create

time

Passage One

Questions 46 to 50 are based on the following passage.

The

Ebro

Delta,

in

Spain,

famous

as

a

battleground

during

the

Spanish

Civil

War,

is

now

the

setting for a different contest, one that is pitting rice farmers against two enemies: the rice-eating

giant apple snail, and rising sea levels. What happens here will have a bearing on the future of

European rice production and the overall health of southern European wetlands.

Located on the Mediterranean just two hours south of Barcelona, the Ebro Delta produces 120

million

kilograms

of

rice

a

year,

making

it

one

of

the

continent’s

most

important

rice

-growing

areas.

As

the

sea

creeps

into

these

fresh-water

marshes,

however,

rising

salinity

（盐分）

is

hampering rice production. At the same time, this sea-water also kills off the greedy giant apple

snail,

an

introduced

pest

that

feeds

on

young

rice

plants.

The

most

promising

strategy

has

become to harness one foe against the other.

The

battle

is

currently

being

waged

on

land,

in

greenhouses

at

the

University

of

Barcelona.

Scientists

working

under

the

banner

“Project

Neurice”

are

seeking

varieties

of

rice

that

can

withstand the increasing salinity without losing the absorbency that makes European rice ideal

for traditional Spanish and Italian dishes.

“The project has two sides,” says Xavier Serrat, Neurice project manager and researcher at the

University

of

Barcelona.

“the

short

-term

fight

against

the

snail,

and

a

mid-

to

long-term

fight

against climate change. But the snai

l has given the project greater urgency.”

Originally from South America, the snails were accidentally introduced into the Ebro Delta by

Global Aquatic Tecnologies, a company that raised the snails for fresh-water aquariums

（

水族馆）

,

but failed to prevent their escape. For now, the giant apple snail

’

s presence in Europe is limited

to the Ebro Delta. But the snail continues its march to new territory, says Serrat. “The question is

not if it will reach other rice-

growing areas of Europe, but when.”

Over

the

next

year

and

a

half

investigators

will

test

the

various

strains

of

salt- tolerant

rice

they’ve bred. In 2018, farmers will plant the varieties with the most promise in the Ebro Delta

and Europe’s other two main rice

-growing regions

—

along the Po in Italy, an

d France’s Rhne. A

season

in

the

field

will

help

determine

which,

if

any,

of

the

varieties

are

ready

for

commercialization.

As an EU-funded effort, the search for salt-tolerant varieties of rice is taking place in all three

countries. Each team is crossbreeding a local European short-grain rice with a long-grain Asian

variety that carries the salt- resistant gene. The scientists are breeding successive generations to

arrive at varieties that incorporate salt tolerance but retain about 97 percent of the European rice

does the author mention the Spanish Civil War at the beginning of the passage

A. It had great impact on the life of Spanish rice farmers.

B. It is of great significance in the records of Spanish history.

C. Rice farmers in the Ebro Delta are waging a battle of similar importance.

D. Rice farmers in the Ebro Delta are experiencing as hard a time as in the war.

may be the most effective strategy for rice farmers to employ in fighting their enemies

A. Striking the weaker enemy first

B. Killing two birds with one stone

C. Eliminating the enemy one by one

D. Using one evil to combat the other

48. What do we learn about “Project Neurice”

A. Its goals will have to be realized at a cost.
