While learning the science lessons, I used to get a doubt--why ear, nose, tongue and eyes should be called as special senses? The basic reason is that these are the channels through which we maintain contact with the surroundings. Though apparently it may feel like these are individual sensory organs, they do show some connectivity. Interestingly, our hearing is less sharp after we eat a heavy food. Isn’t it good for a sound nap after a stomach-full meal? That does not mean we go deaf after a meal, but the hearing pitch（強度）does change after a heavy meal.
We usually give credit of the taste to our tongue, but do you know that unless saliva（唾液）dissolves something, our tongue cannot recognize the taste of the food eaten. Taste is nothing but the food chemicals dissolved in the saliva being sensed by the taste buds（味蕾）present on the tongue. Try to dry off your tongue and mouth with a tissue paper and then taste something.
Women are much better smellers than men. They are born with this characteristic ability and can correctly recognize the exact fragrance of the sample. We all can store almost 50,000 different smells, which are strongly tied to the memories.
Pupils（瞳孔）do not respond to light alone, but to the slightest bit of noise around too. Thus surgeons, watchmakers and those professionals who have to perform a much delicate job do prefer to have a sound-free environment. Even a small noise can enlarge their pupils, change the focus and make their vision less clear.
Each and every one of us has a particular or individualistic or characteristic smell, which is unique to us, except the twins. This smell is very subtle yet can be sensed even by a newborn. It may be due to this smell that the newborn recognizes the presence of his parents around.
小題1:What may happen after you have had a rich lunch?
A．Your eyes become weak and can not see well.
B．You may feel energetic and fresh.
C．Your hearing pitch may be decreased.
D．Your tongue may lose the function of taste.
小題2:. What does the author mean by the underlined sentence in paragraph 2?
A．Our tongues can’t be dried while eating something.
B．If your tongue is dried without any saliva on it, it will not work.
C．A tissue paper is the only thing that can be used to dry our tongues.
D．If your tongue is dried with a tissue paper, it may work as well as before.
小題3:What makes each person different from anyone else except twins according to the passage?
A．The number of sensory organs.
B．The functions of sensory organs.
C．The particular smell of a person.
D．The style of one’s behavior.
小題4:Which of the following may be the best title of this passage?
A．The Sensitivity of Sensory Organs
B．The Functions and Connections of Sensory Organs
C．A Newborn’s Sensory Organs
D．Different Senses Between Men and Woman

Five Ways to Rock the Rest of the Semester
With exams around the corner, how can you possibly pack in one more English word, let alone the causes of the Cold War? Don’t worry. Here is our handy guide to help you
Power Down
So you stayed up too late last night reading Mockingjay for the fifth time. Oops! When you’re that fired, your schoolwork suffers. Instead of studying inefficiently while you are sleepy, allow yourself a 15-minute afterschool power nap. Studies show that even a few minutes of shut-eye can improve memory and concentration.
Take Notes
Not quite grasping that super complicated concept in your chemistry class? You may need to change the way you take notes. Instead of recording every word your teacher says, try using visual hints like pictures, symbols and word bubbles. You can even switch computer fonts or pen color for the important stuff.
Dream On
Your bed’s not just for zzz’s. Experts say it may be good to study in bed, too. Why? We’re able to absorb more right before bed because we’re less distracted and the new information stays in our minds as we sleep. So, slide into bed with a textbook or notes, read for 15 minutes, and then turn off the lights for some sweet and smart dreams.
Brain Food
You’re in the middle of a biology exam when your mind goes blank. You knew this stuff cold at home, but now you can’t tell a ribosome from a chloroplast. What’s going on? Your brain’s in need of some refueling. Have some snacks like apple slices or cheese before class, and have plenty of water, too. If your teacher doesn’t mind, pop in a piece of gum during an exam. Some scientists think the chewing increases the flow of oxygen to the brain.
Smart Move
Ugh! You’re taking an English test and you cannot remember the past participle of “understand”. What to do? Skip it. Test taking is all about timing, so don’t waste it on tricky questions. Move ahead and answer everything you know before returning to the ones you don’t. Chances are, once you get back to the toughies, you’ll recall the answer or at the very least, you’ll have a little more time to come up with one that works.
小題1:When taking notes, we can do all these except ______.
A．draw picturesB．change the typefaceC．switch on the computerD．colour the key points
小題2:According to the passage, _____.
A．it’s good to study under the covers for some time every day
B．you cannot skip the difficult questions and go on to the rest
C．you can have some snacks and drink enough water to refresh yourself in exams
D．when taking notes, you should record whatever the teacher says
小題3:What does the underlined phrase “knew this stuff cold” mean?
A．had no clue about itB．were a cold fishC．knew it was coldD．were familiar with
小題4:You have been working on your essay for two hours and your eyes feel tired, you’d better
A．Power downB．dream onC．eat brain foodD．make a smart move

We find that bright children are rarely held back by mixed ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in streaming(把……按能力分班) pupils. It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child. After all，it can be quite discouraging to be at the bottom of the top grade！
Besides, it is rather unreal to grade pupils just according to their intellectual(智力的) ability. This is only one aspect of their total personality. We are concerned to develop the abilities of all our pupils to the full, not just their academic ability. We also value personal qualities and social skills, and we find that mixed-ability teaching contributes to all these aspects of learning.
In our classrooms, we work in various ways. The pupils often work in groups: this gives them the opportunity to learn to co-operate, to share, and to develop leadership skills. They also learn how to deal with personal problems as well as learning how to think, to make decisions, to analyze and evaluate, and to communicate effectively in order to have the ability to become leaders. The pupils learn from each other as well as from the teacher.
Sometimes the pupils work in pairs；sometimes they work on individual tasks , and they can do this at their own speed. They also have some formal class teaching when this is suitable. We encourage our pupils to use the library, and we teach them the skills they need in order to do this efficiently. An advanced pupil can do advanced work：it does not matter what age the child is. We expect our pupils to do their best, not their least, and we give them every encouragement to attain this goal.
小題1:We can know from the passage that the author’ s attitude towards “mixed-ability teaching”  is______.
A．a(chǎn)pprovingB．disapproving C．questioningD．inactive

C．made to remain in the same classes D．prevented from advancing
小題3:Which of the following is NOT MENTIONED in the third paragraph?
A．Pupils also learn to develop their reasoning abilities.
B．Pupils also learn how to participate in teaching activities
C．Group work gives pupils the chance to learn to work together with others.
D．Group work supply pupils with the chance to learn to be good organizers.
小題4:The author’s purpose in writing this passage is to ______.
A．offer advice on the proper use of the library

After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.
　　There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.
　　Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (Although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
　　If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion the counting sheep will put you to sleep!

Passage 1
The information Highway is the road that links computer users to a large number of on-line services; the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowed road, and usually victims are some files, gone forever. Then, of course, there’s Mr. Cool, with his new broad-band connection, who speeds down the highway faster than most of us can go. But don’t trick yourself; he pays for that speeding.

GCSEs not fit for purpose
GCSEs（General Certificate of Secondary Education，普通中等教育證書）encourage "teaching to the test" and may be past their sell-by date, according to Britain's leading business organization. The Confederation of British Industry（CBI） warns that the qualification is stopping teachers delivering an "inspirational classroom experience" and should be replaced.
John Cridland, the CBI director general, said industry faced a shortage of key skills, particularly in science and maths. The CBI（英國工業(yè)聯(lián)合會）, which represents more than 240,000 companies, is also concerned about the 40% of young people who fail to achieve the benchmark of five good GCSE passes including English and maths. The percentage of pupils who reach this standard is the main measure of school success.
Speaking at the launch of a CBI inquiry into education, Cridland argued that abandoning GCSEs could help deliver a full education. "There's something about this GCSE limitation which produces a form of learning ------ teaching for the test.’’
"It frustrates teachers because it stops them delivering that inspirational classroom experience."
The CBI head suggested that raising the school leaving age to 18 – a change that comes into effect in 2015 – is an opportunity to reform the system. "It seems to me that we've raised the participation age to 18 and we're left with an education system that focuses on 16," said Cridland. More than 600,000 children in England, Wales and Northern Ireland are due to take GCSEs this summer.
Many other countries do without a public exam at 16. Finland, the highest performing school system in Europe, has just one public exam, at 18, though children are regularly tested at younger ages.
小題1:What does the author intend to tell us in paragragh1？
A．“Teaching to the test” should be encouraged.
B．We should stop teachers delivering “inspirational experience”.
C．The current qualification is out of date and should be replaced.
D．The Confederation of British Industry should be replaced.
小題2:What’s the main idea of the passage？
A．The British GCSEs are no longer practical and should be reformed.
B．In the GCSEs system , teachers don’t have freedom.
C．Five good GCSEs is hard to achieve.
D．The British Education Department will reform education system.
小題3:The meaning of the underlined word “benchmark” in paragraph 2 may be ______.
A．successB．targetC．standardD．excellent grades
小題4:Where can we find this article?
A．TV seriesB．radio news
C．newspaper education sectionD．government report

As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without many living things.
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight. Very often the effects of pollution are not noticed for many months or years because the first organisms (生物體) to be affected are either plants or plankton (浮游生物). These organisms are the food of fish, birds, and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it is not until dead fish and water birds are seen at the river’s edge or on the sea shore that people realize what is happening.
Where do the substances which pollute water come from? There are two main sources, sewage(污水) and industrial waste. As more detergent (洗滌劑)is used in homes, more of it is finally put into our rivers, lakes and seas.  Detergents harm water birds by breaking down the natural substances which keep their feathers waterproof. Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful since there are many highly poisonous materials in it, such as copper and lead.
So if we want to stop this pollution, the answer is simple. Sewage and industrial waste must be made clean before flowing into the water reservoirs. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.
小題1:Pollution in water is noticed ________.
A．when the first organisms are affected
B．when many fish and birds die
C．when poisons are poured into water
D．As soon as the balance of nature is destroyed
小題2:Living things die in a lake or river because there is no ________.
A．waterB．fishC．PoisonD．oxygen
小題3:The underlined word “waterproof” in the third paragraph means “         ”.
A．full of waterB．not allowing water to go through
C．covered with waterD．cleaned by water
小題4:Which of the following things is /are harmful according to the passage？
A．Industrial waste and chemicalsB．Water in the river
C．Coal and woodD．plastic

Beautiful cars surrounded by even more beautiful models--it’s no secret why the 2012Beijing Auto Show was popular.
The exhibition was held between April 23 and May 2. Although renowned companies showed off their top models, it wasn’t just their expensive sports cars that grabbed people’s attention.
Concept cars are a way for designers to test out their ideas on the public with complete freedom. They can try out cars with special features that could not be massively(批量) produced easily.
Designers don’t have to follow industry rules；they don’t even need to worry about whether their cars would be fllowed on the roads．

The@Ant was inspired by actual ants．According to Car News China，with the help of automated telemetric systems，@Ants are able to“see” other@Ants and compare  destination information. If two are heading the same way for a while, the vehicles connect, with one car’s rear (后面的)wheels matching up with the front wheels of another car．Up to 10@Ants can be put together and will automatically connect to form a“train"．This  will help save energy while traveling, as well reducing traffic jams.
The car sounds like a great idea．Further research will be needed to turn this concept  car into something for the market，but concepts like Chery’s  show how carmakers are  working for cleaner and greener vehicles．It’s like what the@Ant motto says，“Exploring future human beings’lifestyles”．
