D
Let’s do some sleep math.You lost two hours of sleep every night last week because of a big project due on Friday.On Saturday and Sunday,you slept in,getting four extra hours.On Monday morning,you were feeling so bright—eyed that you only had one cup of coffee,instead of your usual two.But don’t be cheated by your energy.You’re still carrying around a heavy load of sleepiness,or what experts call “sleep debt”一in this case something like six hours,almost a full night’s sleep.
Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get.It’s a shortage that grows every time we skim some extra minutes off our nightly sleep.“People get more sleep debt gradually without being noticed,”says William C.Dement,founder of the Stanford University Sleep Clinic.Studies show that such short term sleep lack leads to a foggy brain,worsened vision,and trouble remembering.Long-term effects include obesity(肥胖),insulin(胰岛素)resistance,and heart disease.A survey by the National Sleep Foundation reports that we’re losing one hour of sleep each night——more than two full weeks of sleep every year.
The good news is that,like all debt,with some work,sleep debt can be repaid.Adding all extra hour or two of sleep a night is the way to catch up.For the long-term lack of sleep, take it easy for a few months to get back into a natural sleep pattern.
Go to bed when you are tired,and allow your body to wake you in the morning(no alarm clock allowed).You may find yourself catatonic(有紧张症的)in the beginning of the recovery cycle:expect to have ten hours shut—eye per night;As the days pass,however,the amount of sleeping time will gradually decrease.
So earn back that lost sleep and follow the rules of your innate(固有的)sleep needs. You’ll feel better.“When you put away sleep debt,you become a superman,”says Stanford"s Dement,talking about the improved mental and physical capabilities that come with being well rested.
53.If you have short-term sleep lack,you may___________.   
A.put on weight    B.get heart disease  C.hate eating food   D.have a poor sight
54.The example of sleep math is used to show______.
A.in what case you build up a sleep debt
B.in what way you can make up for lack of sleep
C.why you are energetic even without enough sleep
D.why you need six hours’sleep every night
55.By saying the underlined sentence,Dement means that______.
A.you need a lot of sleep to be a superman
B.you will be in a good state with enough sleep
C.you need to be a superman to repay sleep debt   
D.you will become a superman with more sleep debt
56.What might be the most suitable title for the passage?   
A.How can you keep energetic?    B.What is sleep debt?
C.Can you catch up on lost sleep?  D.Can coffee refresh you?

What is it that makes people happy? Youth, health, a good job, good looks, a flash car? None of these things, Spanish experts say.
The concept(概念) of happiness is thought to be determined by genetics, while the rest depends on childhood environment and the process(过程) of growing up. Perhaps the most surprising thing about happiness is coming under increasingly close examination in Spain.
As the nation rises to the club of the world"s wealthiest countries, people are discovering that material(物质的) things do not bring happiness.
"Most people use money as a measure of human value," says Jesus Ynfante, author of a book on Spain"s 300 biggest fortunes.  "Expensive products are regarded as the best. The rich are admired simply for being rich," Ynfante said.
Yet psychologists(心理学家) warn that happiness as a moment of ecstatic pleasure(狂喜)--something that, by definition(定义) ,cannot last--while others speak of it as peace and acceptance of oneself. Polls(问卷调查) in different countries indicate that between 65 and 85 percent of the world"s population regard themselves as reasonably happy.
Around 40 percent of a person"s happiness is that it has little to do with age, health, wealth, or other values thought to be important in Western society. For most Spaniards, happiness is linked with feeling close to other people. Happy people accept their limitations and set themselves reachable goals, experts say.
There are life-style choices that favour happiness, such as exercise, eating carbohydrates and exposing oneself to sunlight. But the main secret of happiness is to take pleasure in small things.
“If you are given a choice between eternal(永久的)happiness and a cheese sandwich, take the sandwich,” advises musician Julian Hernandez.
58. Spain, as this passage tells us, __________.
A. has built more clubs than the other countries
B. has owned the largest group of experts

D. has produced the most wealth in the world
59. It can be concluded that Jesus Ynfante is__________.
A. a famous expert           B. a famous psychologist
C. one of the richest Spaniards   D. familiar with the richest Spaniards
60.As psychologists warn in this passage, people can"t feel happy even if they_________.
A. have too much money      B. only care about themselves
C. don"t do any homework     D. have a few relations
61 Happy people, as we can find in this passage, __________.
A. are always full of feelings                  B. are always born in rich families
C. always enjoy every achievement they get       D. always look down upon themselves

D
Jupiter is the largest planet in our solar system. It is also one of the most interesting. It was named after Jupiter, the most important of the Roman gods, and nicknamed the “King of Planets.” It is the fifth planet from the sun and the fourth brightest object in the sky. Before the invention of the telescope, Jupiter was thought to be a bright star.
In 1610, the famous astronomer Galileo realised that Jupiter was actually a planet. He also noticed that it had four large moons. These are known as the Galilean moons. The biggest is Ganymede, and it is larger than the planets Pluto and Mercury. Next in size is Callisto, which is the farthest away from Jupiter. It is the closest to the planet, and has a lot of active volcanoes. The smallest of the Galilean moons is Europa. Europa is covered in ice, and scientists believe there may be an ocean underneath.
Galileo"s discovery that Jupiter was not a star but a planet was very important. Before this time, people believed the Earth to be the centre of the universe. They thought that the sun, stars, and other planets all revolved around the Earth. However, Galileo proved that the sun was at the centre of the universe!
(A) Jupiter is farther out in the solar system than Earth, so it takes longer to revolve around the sun. (B) However, a day on Jupiter is much shorter, only 9.8 Earth hours. (C) This is because it spins(旋转) a lot faster than the Earth does. (D)
Another of Jupiter"s interesting features(特性) is its “Great Red Spot.” On the surface of the planet is a large red spot. The spot is actually a huge storm like a hurricane, but bigger. It covers an area twice as big as the Earth and has been going on for at least 400 years!
62. What is the passage mainly about?
A. Features of the planet Jupiter.     
B. Differences between Jupiter and other planets.
C. Galileo"s accomplishments in astronomy(天文).
D. How Jupiter moves in the solar system.
63. According to Paragraph 3, why is Galileo"s discovery important?
A. Because Jupiter was thought to be smaller than Earth.
B. Because people knew that Earth is not the only planet.
C. Because it meant that the planet goes around the Earth.
D. Because it proved that Earth is not the centre of the universe.
64. The underlined word “revolved” in the third paragraph is closest in meaning to           .
A. approached        B. stopped            C. sped up            D. circled
65. Where would the following sentence best fit into Paragraph 4, (A), (B), (C) or (D)?
This means that one year on Jupiter is as long as 11.6 Earth years.

As a teenager of the digital era, it is really hard to say no to fantastic electronic gadgets(电子产品). Many of us can’t get through a day without using our mobile phones or checking our e-mails. No matter if we’re “@home”, “@school” or“@play”, living without technological toys seems more and more unthinkable.

  Are you feeling stressed out? Anxious? Is your mind racing in circles? Are you worried about all the things you have to get done? Here’s a quick-acting trick that can make you feel better.
  If you’re sitting at a desk, place the palm of your hand on the desk, and take a moment to focus on what the surface of the desk feels like. Is it hot or cold, rough or smooth? Put all of your attention on the sensations in your palm, on how the desk feels underneath your hand. If you are not at a desk, do the same exercise by placing your palm on any nearby object—a wall, a chair, even your opposite arm.
When you are feeling stressed, your thoughts tend to take on a life of their own. Yon may be thinking about things you wish you had done differently in the past or worrying about things that you have to do in the future. These thoughts will make you feel anxious. The anxiety, in turn, increases the number of anxious thoughts.
If you can ground yourself even for a moment in the present, you will break the cycle and feel instant relief. Paying attention to what objects in your environment feel like forces you to pay more attention to the present moment than to negative, anxiety-provoking thoughts about the past or about the future.
Try using your other senses too:
Try closing your eyes for a second (don’t try this while driving!) and breath deeply through your nose. What do you smell?
When eating, put all your attention on how your food tastes.
What do you hear? What little noises are there around you that you didn’t notice before?
Look closely at an ordinary object. Do you see anything you haven’t noticed before?
46.By saying “Is your mind racing in circles”, the author intends to mean that_______.
A.you did something wrong in the past and wouldn’t forgive yourself
B.your mind is quick and bright when in a state of anxiety
C.you are thinking in a stupid way when anxious thoughts worries you a lot
D.you worried a lot and the anxious thoughts will increase your anxiety
47.The author advises to put your palm on the desk or any things nearby in order to______.
A.play a small trick                B.feel the surface of the object
C.do some exercises                D.reduce your anxiety
48.The writer mentioned some senses that could be used to reduce stress except the______.
A.sense of touching            B.sense of smell
C.sense of humour            D.sense of listening
49.Which of the following can be served as a title for the passage?
