American researchers have developed a technique that may become an important tool in fighting AIDS virus from attacking its target-cells in the body's defense system．When AIDS virus enters the blood，it searches for blood cells called T4 lymphocytes(淋巴細(xì)胞)．The virus connects to the outside of T4 lymphocytes．Then it forces its way inside．There it directs the cells' genetic material to produce copies of the AIDS virus．This is how AIDS spreads．
Researchers think they may be able to stop AIDS from connecting to T4 ceils．When AIDS virus finds a T4 cell，it actually connects to a part of the cell called CD4 protein．
Researchers want to fool the virus by putting copies or clones of the CD4 protein into the blood．This way the AIDS virus will connect to cloned protein instead of the real ones．Scientists use genetic engineering methods to make the clones．Normally a CD4 protein remains on the T4 cell at all times；the AIDS virus must go to it．
In a new technique，however，the cloned CD4 protein is not connected to a cell．It floats freely，so a lot more can be put into the blood to keep the AIDS virus away from real CD4 protein on T4 cells．One report says the．AIDS virus connects to cloned protein just as effectively as it connects to real protein．That report was based on tests with blood cells grown in labs．The technique is just now beginning to be tested in animals．If successful，it may be tested in humans within a year．
小題1:The new technique can     .
A．cure AIDS
B．kill the AIDS virus
C．prevent the AIDS virus from spreading
D．produce new anti-AIDS cells
小題2:When the AIDS virus enters the blood，it is reproduced by     .
A．itself
B．the blood cells
C．the CD4 protein
D．the genetic material of T4 lymphocytes
小題3:The AIDS virus connects to cloned protein instead of the real CD4 protein because    .
A．cloned protein stays On the T4 cells
B．it connects to cloned protein more effectively
C．cloned protein is made by genetic engineering methods
D．cloned protein floats freely，and many more can be put into the blood
小題4:Which of the following statements is NOT true?
A．The new technique has been tested in labs．
B．The new technique is being tested in animals．
C．The new technique may be tested in humans．
D．The new technique is now under clinic test．
小題5:The best title for this passage is     ．
A．AIDS-a deadly disease
B．A new technique in fighting AIDS
C．The spread of AIDS virus
D．The cloned CD4 protein

小題1:C
小題2:D

From good reading we can derive pleasure, companionship, experience, and instruction. A good book may absorb our attention so completely that for the time being we forget our surroundings and even our identity. Reading good books is one of the greatest pleasures in life. It increases our contentment when we are cheerful, and lessens our troubles when we are sad. Whatever may be our main purpose in reading, our contact with good books should never fail to give us enjoyment and satisfaction.
With a good book in our hands we need never be lonely. Whether the characters portrayed are taken from real life or are purely imaginary, they may become our companions and friends. In the pages of books we can walk with the wise and the good of all lands and all times. The people we meet in books may delight us either because they resemble human friends whom we hold dear or because they present unfamiliar types whom we are glad to welcome as new acquaintances. Our human friends sometimes may bore us, but the friends we make in books need never weary us with their company. By turning the page we can dismiss them without any fear of hurting their feelings. When human friends desert us, good books are always ready to give us friendship, sympathy, and encouragement. One of the most valuable gifts bestowed by books is experience. Few of us can travel far from home or have a wide range of experiences, but all of us can lead varied lives through the pages of books. Whether we wish to escape from the seemingly dull realities of everyday life or whether we long to visit some far-off place, a book will help us when nothing else can. To travel by book we need no bank account to pay our way; no airship or ocean liner or stream-lined train to transport us; no passport to enter the land of our heart's desire. Through books we may get the thrill of hazardous adventure without danger. We can climb lofty mountains, brave the perils of an Antarctic winter, or cross the scorching sands of the desert, all without hardship. In books we may visit the studios of Hollywood; we may mingle with the gay throngs of the Paris boulevards; we may join the picturesque peasants in an Alpine village or the kindly natives on a South Sea island. Indeed, through books the whole world is ours for the asking. The possibilities of our literary experiences are almost unlimited. The beauties of nature, the enjoyment of music, the treasures of art, the triumphs of architecture, the marvels of engineering, are all open to the wonder and enjoyment of those who read.
小題1:Why is it that we sometimes forget our surroundings and even our identity while reading?
A．No one has come to disturb you.
B．Everything is so quiet and calm around you.
C．The book you are reading is so interesting and attractive.
D．Your book is overdue; you are finishing it at a very fast speed.
小題2:How would you account for the fact that people like their acquaintances in books even more?
A．They resemble human friends exactly.
B．They are unfamiliar types we like.
C．They never desert us.
D．They never hurt our feelings.
小題3:Which of the following is true?
A．Your wish to visit some far-off place can be realized through the pages of the books.
B．To escape from the dull realities of everyday life you should take up reading.
C．Books can always help you to live a colorful life.
D．You may obtain valuable experience from reading good books.
小題4: The word “weary” means ______.
A．“to attract someone’s attention”
B．“to distract someone’s attention”
C．“to make someone very tired”
D．“to make someone interested”
小題5:“... the whole world is ours for the asking” implies that ____________.
A．in books the world is more accessible to us
B．we can ask to go anywhere in the world
C．we can make a claim to everything in this world
D．we can make a round-the-world trip free of charge

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

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(chǎn) planet which has a clear neighborhood around its orbit
B．a(chǎn) satellite of Neptune which was discovered in 1930
C．the smallest planet in the solar system
D．a(chǎn) 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.

Sea turtles come in many different sizes, shapes and colors. The shell of each sea turtle species is different in length, color, shape and the arrangement of the scales（鱗片）.
Sea turtles do not have teeth but use their jaws （下巴）to eat. Their sense of smell is excellent. Their eyesight underwater is good, but they have near-sighted eyes out of water. Their special bodies make them adapt to life at sea. However, sea turtles maintain（保持） close ties to land.
Female sea turtles have to go to the seaside to lay their eggs in the sand; therefore, all baby sea turtles begin their lives on land. Most research on sea turtles has been focused on female turtles nesting and the baby sea turtles in the nest, largely because they can be found most easily. After decades of studying sea turtles, much has been learned about. However, many mysteries（謎） still remain.
Researchers do not yet know how long baby turtles spend in the open sea, or exactly where they go. People believe they spend their earliest years floating in the sea, where they do little more than eat and grow. Once turtles reach dinner-plate size, they appear at feeding grounds in waters near the shore. They grow slowly and take between 15 and 50 years to grow old enough to bear baby sea turtles, depending on the species. There is no way to know the age of a sea turtle from its physical appearance. It is believed that some species can live for over 100 years.
小題1:Which of the following statements is NOT true about sea turtles?
A．They don’t use teeth to eat.
B．They have a good sense of smell.
C．Sea turtles are more adaptable to life at sea.
D．Different species have different shells.
小題2:The underlined phrase “near-sighted eyes” in the second paragraph means_____.
A．good eyesightB．bad eyes
C．excellent eyesD．poor eyesight
小題3:Which of the following questions is answered in the text?
A．Why do female turtles lay eggs on land?
B．Why can’t people tell how old a sea turtle is from its appearance?
C．Where do the baby turtles usually go?
D．Do sea turtles grow very fast?
小題4:What would be the best title for the text?
A．Mysteries About Sea Turtles
B．Baby and Female Sea Turtles
C．The Growth of Different Sea Turtles
D．The Characteristics（特點(diǎn)） of Sea Turtles

For those who are tired doing the laundry, Samsung has found an answer: a washing machine that can tell you when your laundry is done via a smartphone app(application).
Strange though it may seem — “my wife already does that” was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show (CES) this week — Samsung is just one of many appliance makers racing to install (安裝) a large number of internet-connected features in machines in an effort to make them “smart”.
Last year, it was a refrigerator that tweeted. This year, it’s Wi-Fi-enabled laundry machines and fridges that can tell you when your groceries are going bad.
The washers and dryers, available starting in the spring, connect to any smartphone through a downloadable application. The phone can then be used as a remote control, so the machines can be turned on and off while their owners is at work or on the bus.
Samsung says it’s not just something new — the app connection actually has some practical uses.
“If you started to dry clothes in the morning and forgot to take them out, you can go to your phone and restart your dryer for the time when come home, so your clothes are refreshed and ready to go,” said spokesperson Amy Schmidt.
The company also says that with electricity rate(電價(jià))varying depending on the time of day, more control over when the machines are used can help save money.
Perhaps, but what they will probably really accomplish is what all good technologies do —enable laziness. Rather than getting up to check on whether the laundry is done, users will instead monitor it on their phones while watching TV.
小題1:What can be inferred from the common response of the attendees at the CES?
A．The machine will be a big success.
B．their wives like doing the laundry.
C．The machine is unrelated to their life.
D．This kind of technology is familiar to them.
小題2:What can we learn about the new laundry machines?
A．They can tell you when your clothes need washing
B．They can be controlled with a smartphone
C．They are difficult to operate
D．They are sold at a low price
小題3:We can conclude form Samsung’s statements that ___________.
A．the app connection makes life easier
B．it is better to dry clothes in the morning
C．smartphone can shorten the drying time
D．we should refresh clothes back at home
小題4:What is the main idea of the last paragraph?
A．The laundry should be frequently checked
B．Lazy people like using such machines
C．Good technologies also cause problems
D．Television may help do the laundry.
