阅读理解。 A vertical farm is a concept farm which is planted on levels or floors - 高中英语试题 - 超级试练试题库

阅读理解。     A vertical farm is a concept farm which is planted on levels or floors.A sky scraper type
building can house a vertical farm.Since the garden is built upwards,rather than outwards,it
requires much less space than a conventional(传统的) farm.
     The world is quickly running out of room for conventional farming.Vertical farms could be
a key to this situation.An 18story vertical farm could feed as many as 50,000 people,all in an
area which is the size of the average city block.Vertical farms in the city could cut down on
transportation costs as well.Think about the amount of fuel it takes to transport food from
farmland to city.The resources saved would be surprising. Besides saving travel time,food
would be delivered in fresher condition and with less damage.
     There is a growing concern about the use of pesticides in agriculture today.But the vertical
farm would be a greenhouse type environment, avoiding the need for a large number of
pesticides.Vertical farms can be built in a contained space,therefore they are an excellent
solution for living well in an environment far different from our own.Hydroponics(水耕法)
could be a big part of vertical gardening.This would reduce the amount of soil needed to grow
food.Of course,not all food does well with this type of planting,but there are many crops
that actually seem to do better.
     In some climates,a lack of sunlight creates a short growing season. The solar power option
may not work as well here.The addition of grow lights would make it possible to grow crops
in vertical gardens in these areas.In other words,we could grow crops in areas where we never
could before.
     Vertical farms may just be a concept for now,but they are a concept that will solve many
of our problems in the future.1.According to the passage, a vertical farm________.A．is mainly built outwards
B．is only an environmental friendly farm
C．is planted on levels upwards
D．is dependent on solar power2.The second paragraph is mainly about________.A．the meaning of a vertical farm
B．the future of a vertical farm
C．the cost of a vertical farm
D．the benefit of a vertical farm3.Compared to the conventional farm, the vertical farm can________.A．help to protect the limited gardens
B．reduce the harmful effect of pesticides
C．depend far less on sunlight
D．greatly increase the use of soil4.It can be learned from the passage that vertical farms________.A．have been put into use
B．need less room than conventional farms
C．only use hydroponics to grow food
D．may increase the transportation costs5.What would be the best title for the passage?A．Vertical farms for our future
B．Vertical farms and green skyscrapers

     Sydney-A shark savaged a schoolboy"s leg while he was surfing with his father at a beach in Sydney
on February 23. It was the third shark attack along the coast of Australia"s largest city in a month.
     The 15yearold boy and his father were in the water off Avalon, on Sydney"s northern beaches,
around dawn when he was attacked. The city"s beaches are packed with locals and tourists during the
summer months.
     "The father heard a scream and turned to see his son thrashing(激烈扭动)about in the water, "police
said. "Fortunately, the shark swam away and the boy was helped to the shore by his father. "
     Lifesaving Club spokesman Nick Miller said, "It got him around the top of his left leg and the father
came and dragged him out of water. "He said the boy was bleeding heavily when he was brought to the
shore. "There was a lot of pain, as you can imagine. "The teenager was airlifted to hospital for treatment
for leg injuries.
     Police said the bites "cut through to the bone", but the boy did not appear to have sustained any
fractures (骨折).  He was in a stable condition now.
     Several beaches were closed after the attack. Water police and lifeguards were searching for the
shark, while police hoped to identify its species by the shape of the bite marks. But they said it was too
early to say what type of shark attacked the boy. "I don"t even know if he saw it, "Miller said.
     Many shark species live in the waters off Sydney"s beaches, but attacks on humans are still relatively
rare.  However, there were two attacks on successive days earlier this month, one on a navy diver in
Sydney harbor, not far from the famous Opera House, and the other on a surfer at the city"s
worldfamous Bondi beach.
    Fishermen say shark numbers are on the rise. There is a ban on commercial fishing in the harbor,
which has increased fish stocks. Marine experts also claim environmental protection has created a
cleaner environment, attracting sharks closer to the shore as they chase fish. Many shark species,
including the Great White-the maneaters made famous in Steven Spielberg"s Jaws-are protected in
Australian waters. 1. The report mainly tells us ________. A. shark attacks on humans are on the rise
B. sharks attacked humans three times in one month
C. a boy was attacked by a shark at a Sydney beach
D. shark numbers are increasing in the waters off Sydney"s beaches2. The underlined word "savaged" in the first paragraph probably means "________".  A. attracted
B. dragged
C. bit
D. packed3. What do we know about the city of Sydney from the passage?A. It is one of the largest cities in Australia.
B. Sydney harbor is not far from the famous Opera House.
C. There are many locals and tourists on its coast all the year round.
D. There are few shark species in the waters off Sydney"s beaches. 4.  About the injury of the boy we know that ________. A. he was losing much blood when he was dragged out
B. he was very nervous when he was sent to hospital
C. he may be in danger of losing his leg
D. he was injured in the right leg5. All the following are the causes of Australia"s sharks" increasing EXCEPT that ________. A. environmental protection has created a cleaner environment
B. a ban on commercial fishing has increased fish numbers
C. many shark species are protected in Australian waters
D. the film Jaws has made the Great White famous

We"ve used the wind as an energy source for a long time.The Babylonians and Chinese were using wind power to pump water for irrigating crops 4000 years ago, and sailing boats were around long before
that.Wind power was used in the Middle Ages, in Europe, to grind (磨碎) corn, which is where the term "windmill" comes from.

     We can use the energy in the wind by building a tall tower, with a large propellor on the top.The wind
blows the propellor round, which turns a generator to produce electricity.
     We tend  to build many of these  towers together, to make a "wind farm" and produce more electricity.The more towers, the more wind, and the larger the propellors, the more electricity we can make.It"s only worth building wind farms in places that have strong, steady winds, although boats and caravans (大篷车) increasingly have small wind generators to help keep their batteries charged.
     The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains-places where the wind is strong and reliable.Some are offshore.To be worthwhile, you need
an average wind speed of around 25 km/h.Most wind farms in the UK are in Cornwall or Wales.Isolated places such as farms may have their own wind generators.In California, several "wind farms" supply
electricity to homes around Los Angeles.
      The propellors are large, to obtain energy from the largest possible volume of air.The blades can be
angled to cope with varying wind speeds.Some designs use vertical turbines (垂直涡轮机), which don"t
need to be turned to face the wind.The towers are tall, to get the propellors as high as possible, up to
where the wind is stronger.This means that the land beneath can still be used for farming.

1. The first paragraph aims to introduce to us________.A. the function of wind power
B. the source of wind power
C. the nations using wind power
D. the history of using wind power2. How does a wind power work?A. The generator turns the propeller blades and produce electricity.
B. The tall tower helps turn the energy in the air into electricity.
C. Warm air rises and makes the propellor move round.
D. The propellor blown round by wind turns the generator to produce electricity.3. The best places for building the wind farm are places where______.A. boats and caravans can often be seen
B. isolated farms don"t have enough electricity
C. there are less human activities
D. the wind is strong and reliable4. We can infer from the passage that________.A. wind farms will not take up too much farming land
B. wind farms need no fuel because wind is free
C. the blades can be angled to turn to face the wind wherever it comes from
D. the higher and larger the towers are, the stronger the wind is5. What can be a suitable title for the passage?A. Where to build a wind farm
B. ABC of the using of wind energy
C. How to make best use of wind
D. Wind energy is the best energy

阅读理解. Charter schools operate with public money but without many of the rules that govern
traditional public schools.In the United States the rules for charter schools differ from state
to state.But in general these schools have greater freedom to decide what to teach and how
to teach it.

     The "charter" is a performance contract.It establishes the goals of the school and other
details like how student performance will be measured.Fortyseven million students attend
traditional public schools.But more than a million students attend charter schools.
     And now a group of charter schools have formed the Green Charter Schools Network.
The idea is to have environmentally friendly school buildings but to also go further than that.
The schools teach students to become involved in community issues that affect them and
the environment.For example,young children grow crops in a school garden and learn
about healthy eating.Older students help recycle waste from the cafeteria.And local schools
share what they grow in community gardens with people in need.
     Jim McGrath is president of the Green Charter Schools Network.He says there are
about 200 "green" charter schools across the United States.He says the plan is to also
include traditional public schools as well as private schools.
     Jim McGrath:"The most important thing is that every one of us-every child,every
adult-has a responsibility that their action,every action we make has an effect on the earth
that we live in.And that our natural resources are not unlimited.And that if we want a
positive earth for future generations,we all need to make commitments to be agents of
change so that we don"t destroy our natural resources."
     T he Green Charter Schools Network holds its first national conference this October
in Minnesota.It will include companies and organizations like Waste Management and the
United States Green Building Council.We sincerely hope that their goal is to expand the
movement across the country.
1．Charter schools are quite different from public ones in that____.A．they are operated by public money

B．paint the school buildings in the color of green
C．measure the students with the same standards
D．get students involved in environment friendly activities3．The following statements about the Network are true EXCEPT________.A．It only concerns the charter schools in the US
B．It holds its first national conference in Minnesota
C．It will benefit both the schools and the communities
D．It promotes different schools to share their achievements4．According to Jim McGrath,________.A．people"s action plays little part in nature
B．natural resources are abundant for people to use
C．students should be taught to be responsible for the world
D．everyone should make efforts to change the positive nature5．What"s the writer"s purpose of writing this passage?A．To criticize the traditional education system.
B．To encourage the students to adopt healthy eating.
C．To inspire people to recycle waste from the cafeteria.
D．To arouse the schools to take action to protect the earth.

     A new study in West Africa shows how farm irrigation systems powered by the sun can
produce more food and money for villagers.The study in Benin found that solarpowered pumps
are effective in supplying water,especially during the long dry season.
     SubSaharan Africa is the part of the world with the least food security.The United Nations
Food and Agriculture Organization estimates that more than one billion of the world"s people
faced hunger last year.Around 265 million of them live south of the Sahara Desert.Lack of
rainfall is one of their main causes of food shortages.
     Jennifer Burney from Stanford University in California led the study.The research team
helped build three solarpowered drip irrigation (滴灌) systems in northern Benin.Between
30 and 35 women used each system to pump water from the ground or a stream.Each
woman was responsible for farming her own 120 square meters of land.They also farmed
other land collectively.
     The solarpowered irrigation systems produced an average of nearly two tons of vegetables
per month.During the first year,the women kept a monthly average of almost nine kilograms
of vegetables for home use.They sold the surplus produce at local markets.The earnings
greatly increased their ability to buy food during the dry season which can last six to nine
months.People in the two villages with the systems were able to eat three to five more
servings of vegetables per day.But making the surplus available at markets also had a wider
effect.
     The study compared the villages with two others where women farmed with traditional
methods like carrying water in buckets.The amount of vegetables eaten in those villages also
increased,though not as much.The researchers note that only four percent of the cropland in
SubSaharan Africa is irrigated.Using solar power to pump water has higher costs at first.But
the study says it can be more economical in the long term than using fuels like gasoline,diesel
or kerosene.And solar power is environmentally friendly.

1．Food security in SubSaharan Africa is insufficient mainly because of________.A．lack of rainfall
B．limitation of farmland
C．a small crop variety
D．little sunlight2．From the third paragraph we know that________.A．water is wasted by using the system
B．the farmers irrigate the land together
C．all farmers use irrigation systems in northern Benin
D．the solarpowered systems take up more manpower3．The underlined word "surplus" in the 4th paragraph most probably means________.A．special
B．unnecessary
C．extra
D．abandoned4．Using solar power to pump water has advantages EXCEPT that________.A．solar energy has higher cost at first
B．solar power helps to protect environment
C．solar power helps farmers increase earnings
D．solar energy can be more economical in the long run5．What can be the best title for the text?A．Manpower affects rainfall in Africa
B．Irrigation by carrying water in buckets
C．Solarpowered pumps aid African farmers
D．Vegetable supply increased in African villages
