Farming is moving indoors, where the sun never shines, where rainfall is irrelevant (無關的) and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature,humidity,air quality and nutrition. It could be in a New York high- rise or a complex (建筑群) in the Saudi desert. It may be an answer to the world’s food problems.
The world already is having trouble feeding itself. Half the people on Earth live in cities, and nearly half of those – about 3 billion – are hungry or ill–fed. Food prices, currently increasing, are badly affected by dryness, floods and the cost of energy required to plant, harvest and transport it. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world already are using water available to the last drop. And the world is getting more crowded: by mid-century, the global population will grow from 6.8 billion to 9 billion.
To feed so many people may require expanding farmland at the expense of forests and wilderness, or finding ways to greatly increase crop output.
Gertjan Meeuws and three other Dutch bioengineers grow vegetables and house plants in closed and regulated environments. In their research station, water flows into the pans when needed, and the temperature is kept constant. Lights go on and off, creating “day” and “night”, but according to the rhythm of the plant.
Meeuws says a building of 100 square meters and layers of plants could provide a daily diet of 200 grams of fresh fruit and vegetables for the entire population of Ken Bosch, about 140,000 people. Their idea isn’t to grow foods that require much space, like corn or potatoes.
Sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoor agriculture. And city farming means producing food near the consumer, so there’s on need to transport it long distances.
小題1:According to the text, Gertjan Meeuws’ farming _______.
A.can be used for corn production
B.is much like greenhouse farming
C.is adaptable to any environment
D.uses more water than outdoor farming
小題2:What is the second paragraph mainly about ?
A.The effect of climateB.The hungry people in cities.
C.The world’s food problem.D.The world’s increasing population.
小題3:What is the purpose of the text ?
A.To compare traditional and indoor farming.
B.To discuss the influence of climate change.
C.To explain the world’s food problem.
D.To introduce a new model of farming.

We must do what we can to protect the plants because plants are very important for living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores(胚芽). Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.
小題1:Plants can make food from______.
A.flower, water and airB.water, sunlight and air
C.air, water and soilD.air, sun and light
小題2:The main idea of the first paragraph is that ______.
A.plants are important for life
B.plants cannot grow without air
C.there are many plants in the world
D.we can not live without water
小題3:What can we infer(推斷) from the passage?
A.Of all living things animals are most important
B.Spores are seeds
C.All fruits of flowering plants have seeds
D.Without plants, man will die out
小題4:This passage may be taken from______.
A.a medicine bookB.a novel
C.a science magazineD.an experiment report
小題5:The underlined word “protected” in the passage can be replaced by ______.
A.damagedB.pollutedC.preventedD.guarded

A farm planted levels or floors is called a vertical(垂直的)farm. A skyscraper type building can house a vertical farm. Since the garden is built upwards,rather than outwards,it requires much less space than a conventional 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(殺蟲劑) 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.
小題1:According to the passage, a vertical farm________.
A.is mainly built outwards
B.is dependent on solar power
C.is planted on levels upwards
D.is only an environmental friendly farm
小題2:Compared to the conventional farm, the vertical farm can________.
A.depend far less on sunlight
B.greatly increase the use of soil
C.help to protect the limited gardens
D.reduce the use of harmful pesticides
小題3:It can be learned from the passage that vertical farms________.
A.have been put into use
B.only use hydroponics to grow food
C.need less room than conventional farms
D.may increase the transportation costs
小題4:What would be the best title for the passage?
A.Vertical farms for our future
B.Ways to deal with future problems
C.Vertical farms and green skyscrapers
D.Making Full Use of Our Limited Land

What would you do if Martians (火星人) kidnapped (綁架) your mom? In the 3-D animated movie Mars Needs Moms, a young boy named Milo finds himself in this exact difficult situation. The aliens want to steal Milo’s mother’s “momness” for their own young. Now it’s up to the 9-year-old to get his mom back before she is lost forever.
Every good action movie has a bad guy. The villain (反派角色) in this film is the Martian Supervisor, played by Mindy Sterling. The Supervisor has an icy cold heart. Remarkably, Sterling acted out almost all of her scenes in a special Martian language created just for the movie. “Learning Martian was a piece of cake,” Sterling said. “There wasn’t too much to learn; sometimes, I just made it up!”
Anyone who has a mother will be moved by this movie. In fact, anyone who loves someone will be moved by this movie. Maybe it is because the story was inspired by a real-life event. The movie is based on a novel by prize-winning cartoonist Berkeley Breathed. He wrote the book after a dinner-table incident between his wife and son, who was then 4 years old. That night, Breathed’s son had thrown his broccoli into the air and rushed out of the room angrily, yelling at his mother on the way out. Breathed told his son, “You might think differently about your mom if she were kidnapped by Martians.” He wrote the novel that same evening.
All kids get into arguments with their parents. The fights may be about homework, chores or eating vegetables. Mars Needs Moms tells us to look past these silly disagreements and to remember the importance of family and the things that really matter.
小題1:In the movie Mars Needs Moms the aliens want to _____.
A.kill Milo’s mother
B.take Milo as their kid

It is always hard for a small fish to live in a big pond. Pluto's recent departure from the classical planet family clearly proves that size really matters.
Astronomers voted on August 24 to create the first scientific definition of the word planet, and Pluto obviously didn't make the cut. It turned out to be only a "dwarf planet" (矮行星). After weeks of heated debate, over 2,500 astronomers from 73 countries voted on the definition of a "planet" at a conference of the international Astronomical Union (IAU). According to the definition, a planet must have a clear neighborhood around its orbit. Pluto has widely been considered a planet since its discovery in 1930. Unfortunately, it has a special orbit which overlaps with Neptune's. It is all because, compared with Neptune, Pluto is very small. It is attracted by Neptune's gravity when the two planets get closer.
According to IAU, a "dwarf planet" should have an orbit around the Sun. It will not have a clear neighborhood around its orbit, and must not be a satellite. The new classification means that the science textbooks will have to be updated. The solar system is now made up of the eight "classical planets," together with a number of dwarf planets. The classical planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The debate over Pluto's status started in 1992. After an advanced telescope was sent into space, astronomers started find a belt of objects, which lies beyond Neptune. The belt contains nearly 1,000 objects, including Pluto. As they continued the exploration, scientists recently discovered at least 41 dwarf planets at the edges of the solar system. There are at least two objects of a similar size to Pluto.
It seems that even if the IAU had kept Pluto's status as a planet, the classical theory of nine planets in the solar system would have had to be changed, but the other way around. More dwarf, planets of a similar size to Pluto would join the family of planets. Scientists will probably find many more dwarf planets.
小題1:According to the passage, Pluto is          .
A.a planet which has a clear neighborhood around its orbit
B.a satellite of Neptune which was discovered in 1930
C.the smallest planet in the solar system
D.a planet which has an orbit around the sun
小題2:The sentence "It is always hard for a small fish to live in a big pond" quoted in the beginning of the passage is used to           .
A.tell us a small fish can hardly survive in the big pond
B.tell us the size of an object really matters
C.mean that a small planet can hardly exist in the solar system
D.explain the disappearanee of Pluto in the solar system
小題3:From the last paragraph we can infer that if IAU kept Pluto's status as a planet, the number of planets in the solar system would be        .
A.eightB.nineC.less than nineD.more than nine
小題4:Which of the following statements is NOT true aceording to the passage?
A.According to definition of a "planet", if Pluto were bigger it would not have left the classic planet family.
B.It's quite possible for dwarfs to lose if they compete with big men
C.Pluto has a special orbit which overlap with Neptune's, because it is so small as to be attraeted by Neptune's gravity when the two planets get closer
D.A "dwarf planet", which can not be a satellite without a clear neighborhood around its orbit, should have an orbit around the Sun.

Have you ever suddenly felt that someone you knew was in trouble—and was he? Have you ever dreamed something that came true later? Maybe you have ESP (超感覺知覺).
ESP stands for Extra Sensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.
Here's an example. A woman was ironing clothes. Suddenly she screamed, "My father is dead! I saw him sitting in the chair!" Just then, a telegram came. The woman's father died of a heart attack. He died sitting in a chair.
There are thousands of stories like this one on record. Scientists are studying them to find out what's behind these strange mental messages. Here's another example—one of hundreds of dreams that have come true:
A man dreamed he was walking along a road when a horse and carriage came by. The driver said, "There's room for one more." The man felt the driver seemed dead, so he ran away. The next day, when the man was getting on a crowded bus, the bus driver said, "There's room for one more."
Then the man saw that the driver's face was the same face he had seen in the dream. He wouldn't get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!
Some people say stories like these are coincidences. Others, including some scientists, say that ESP is real. From studies of ESP, we may someday learn more about the human mind.
小題1:According to the passage, the author believes that the sixth sense is_________.
A.in existenceB.imaginativeC.not real D.impossible
小題2:By studying ESP, scientists may get to_________.
A.learn how people tell lies
B.know more about human dreams
C.know more about human mind
D.learn how strange things happen
小題3:In the last paragraph the underlined word "coincidences" probably means ____.
A.things that may not happen
B.things that happen in a dream
C.things that must happen
D.things that happen by accident
小題4:This article is mainly about_________.
A.the human dream B.the sixth sense
C.the human mind D.a crowded bus
