4 . An Epidemic (流行病) of Depression? Seligman is leading the charge in what might be called Happiness Revolution in psychology.Since World War II, psychologists have focused on fixing what is broken---repairing psycholosis(精神病), and neurosis(神经衰弱).Research has piles up steadily when it comes to looking at patients who are neurotic, while the happy or joyful people among us have received little scientific examination.

When Seligman did a search to find academic articles about such “positive psychology” he found only 800 out of 70,000.“Psychologists tend to be concerned with taking a negative 8 person, and helping him get to negative 2,” said Seligman, a University of Pennsylvania psychology professor.“My aim is to take a plus 2 person and boost him to a plus 6.”

In the last 50 years, statistics have shown that we are less happy as a people.“While our quality of life has increased dramatically over that time, and we’ve become richer, we’re in an epidemic of depression,” Seligman said.“Depression is 10 times more common now, and life satisfaction rates are down as well.” Seligman argues that the new science he writes about is shifting psychology’s model away from its narrow-minded focus on pathology(病理学), victimology, and mental illness towards positive emotion, virtue and strength, and positive institutions that increase people’s happiness.If you want to be happy, forget about winning the lottery, getting a nose job, or securing a raise.In his new book, Authentic Happiness, psychologist Martin Seligman argues that overall lifetime happiness is not the result of good genes, money, or even luck.Instead, he says we can boost our own happiness by making use of the strengths and traits that we already have, including kindness, originality, humor, optimism, and generosity.He has named the discipline “Positive Psychology,” arguing that we would be better off building on our own strengths rather than bemoaning, and hence, trying to repair, our weakness.By frequently calling upon their strengths, people can build up natural barriers against misfortune and negative emotions, he said.

To cultivate happiness, we must first find out our individual strengths and virtues.Next, apply the qualities in such a way as to enhance our happiness-generating system.

1. Why could Seligman’s work be called Happiness Revolution?

A．Because happy or joyful people among us also suffer from illness.

B．Because psychology is the emotional characteristic of an individual.

C．Because psychology is the science that deals with mental processes and behavior.

D．Because traditional research on psychology rarely concerns happy or joyful people.

2. What does Seligman mean by saying “take a plus 2 person and boost him to a plus 6”?

A．We should focus on happy or joyful people.

B．The number of happy or joyful people will increase by 4.

C．“Positive psychology” articles need to be published more.

D．Happy people among us also need improve their mentality.

3. According to the passage, traditional opinion of psychology is __________.

A．encouraging

B．optimistic

C．subjective

D．narrow-minded

4. Martin Seligman argues that authentic happiness results from___________.

A．good genes, money or luck

B．positive mental status

C．contented life.

D．a good job.

5. According to the passage, which of the statements might Martin Seligman support?

A．promotion leads to true happiness.

B．We rely on our strengths for happiness.

C．Intelligent people are usually more satisfied.

D．Mental illness should be the focus of psychology.

6. The main topic of the passage is ____________.

A．how we can cultivate our happiness.

B．why material goods can’t boost people.

C．why we should cultivate our happiness.

D．how complicated our happiness-generation system is.

5 . The COVID-19 pandemic has spread far and wide. Because of this, countries around the world have carried out measures to help stop the virus in its tracks. As more people stay inside to stay safe, the outside world seems to have become much quieter. In fact, scientists have seen this change in their research.

Seismologists - scientists who study earthquakes - have heard a lot less seismic（地震的） noise recently.

Seismic noise is made from vibrations (continuous shaking movements) in the ground that are caused by things like ocean waves and human activity, such as construction work and traffic. This noise makes it difficult for scientists to pick up seismic activity that is made at the same frequency.

Thomas Lecocq, a scientist at the Royal Observatory of Belgium, located in Brussels, was the first to notice this phenomenon. According to Lecocq, the amount of seismic noise in Brussels has been reduced by about 30 to 50 percent since mid-March. Interestingly enough, this is around the same time Belgium started its measures. Because of this reduction in background noise, scientists like Lecocq have been able to pick up on smaller earthquakes that some seismic stations - like the one in Brussels - wouldn’t have been able to before.

This phenomenon isn’t unique to Brussels, though. Once Lecocq shared his findings online, seismologists from all over the world echoed similar findings. Celeste Labedz, a graduate student at the California Institute of Technology, mentioned in a tweet that Los Angeles also experienced less background noise. “The drop is seriously wild,” she wrote.

Researchers from the UK, France and New Zealand also noted a decrease in background noise since measures were put in place.

These global efforts to contain the COVID-19 virus have helped to shed light on seismic activity that may have gone unnoticed. It also shows that people are listening to health officials and following lockdown rules. “From the seismological point of view, we can motivate people to say, ‘You feel like you’re alone at home, but we can tell you that everyone is home. Everyone is respecting the rules,’” Lecocq told CNN.

1. What did seismologists find out recently?

A．Reduced seismic vibration makes the Earth quieter.

B．More smaller earthquakes are more likely to happen.

C．Many seismic activities have been detected recently.

D．Seismic noise is caused by vibrations underground.

2. What can we infer from the text?

A．More seismic noise is being picked up.

B．More data on smaller earthquakes is being collected.

C．Scientists will shift their focus to smaller earthquakes.

D．Future big earthquakes must be more accurately predicted.

3. The underlined word “echoed” in Paragraph 5 is closest in meaning to “__________”.

A．repeated

B．demanded

C．explored

D．questioned

4. Which of the following statements does Lecocq mostly probably agree?

A．The drop in seismic noise is unique to Europe.

B．Seismic noise is mainly caused by human activity.

C．Many seismologists wanted tighter restrictions for their research.

D．The phenomenon proved that people are practicing social lockdown rules.

8 . Fran’s husband Tom had a habit of throwing his dirty socks into the laundry basket, but frequently missing by a few inches. It really frustrated Fran when she had to pick up his socks and place them in the basket. After learning the techniques of behavior modification(矫正)，Fran decided to stop nagging(唠叨) her husband and try positive reinforcement(加强). When he missed the basket, she said nothing and quietly picked up his socks. However, one day when his socks actually landed in the target, she quickly reinforced the appropriate behavior by saying, “ I really like it when you put your socks right inside the basket.” She followed this statement with a hug. Within a week, Tom was hitting the target every time, or picking up the socks by hand and placing them inside the basket whenever he missed. Consequently, an argument was avoided.

There is an old saying that” you can catch more flies with honey than vinegar”, which is the principal behind behavior modification. Complaining to someone of doing something, whether it’s a partner or a child, often gets just the opposite response: resistance. But almost everyone respond to positive reinforcement and this approach to changing someone’s behavior takes a little patience and emotional control.

Experts of behavior modification believe habits are learned because of reinforcement from the environment. This theory states that people will always do the behavior that results in the most favorable outcome. Even if in the doing, there are some negative effects. For instance，Fran may have learned from her mother that it really didn’t matter whether her husband’s socks landed in the basket or not. It is because she’d come along and pick them up for him. That was the favorable outcome but, if he only got negative messages from Fran for the same behavior, he didn’t have much motivation to abandon it.

Of course for some people nothing will work, but it’s sure worth a try, for treating them with a hostile attitude probably won’t get you what you want , but it will get you a bad relationship with them. Positive reinforcement can be used with anyone, for any behavior, because all of us resist criticism and respond to praise. So, the next time you want someone to meet your wishes, try a little applause for the desired behavior.

1. Why does the author present Tom and Fran’s story at the beginning of the passage?

A．To show Tom is one of those needing behavior modification.

B．To introduce the techniques of behavior modification.

C．To let the readers know this family.

D．To list ways to get rid of bad habits.

2. Which of the following best fits the principle behind behavior modification?

A．Leaving a child alone when he or she does something wrong.

B．Telling a child not to make the same mistakes again.

C．Taking no notice of one’s occasional good behavior.

D．Praising one for his or her good deeds.

3. Which statement about a habit may the author agree with?

A．Criticism contributes a lot to the formation of a bad habit.

B．Most of our habits are formed in childhood.

C．A habit is usually reinforced by favorable outcome.

D．We can always get along with a person of good habits.

4. What can we learn from Paragraph 4?

A．Positive reinforcement should be applied to anyone.

B．Positive reinforcement works on anyone.

C．By using positive reinforcement we don’t fail to get what we want

D．By using positive reinforcement we can improving our relationship with anyone else.

5. The purpose of the passage is to tell us_____.

A．what behavior modification is

B．the way to get along with others

D．the training of behavior modification

9 . Sucking blood is a risky business. At least for the female mosquitoes that need these nutrients to nurture their developing eggs. Not only do these bugs have to find a suitable blood donor, but once they've had their fill, they have to be able to escape undetected—to avoid the big swat. How they finesse this stealthy departure has just been revealed in the Journal of Experimental Biology.

Feasting(饱餐) on an unsuspecting mammal can double a mosquito's body mass. So how does a fully loaded female heave that added bulk off the skin of her host without triggering its pressure sensors and bringing on that fateful slap? To find out, Florian Muijres of Wageningen University in The Netherlands and his colleagues used cameras that record 13,500 frames per second to capture the takeoff maneuvers of 63 blood-fed malarial mosquitoes.

What they discovered is, when it comes to a soft yet speedy getaway...for female skeeters, the wing's the thing. With a wingbeat frequency of about 600 beats per second...the insects are able to lift themselves lightly off their host. That approach is the opposite of the one favored by most other winged things, says Muijres.

"When most flying animals when they take off, like birds or a fly for, example, they first use their legs to push off very hard, and then when they are in the air, then they start beating their wings and generate aerodynamic lift(气动升力) to be able to fly away. Mosquito does it the other way around. It first starts beating its wings and through the aerodynamic forces these wings generate, their body is being lifted off from the substrate. And then they do gently also push down with their long legs to be able to further power their liftoff. But these forces that are being generated by the legs are relatively small."

In fact, the faint flutter of a mosquito's wings produces less than one third of the force exerted by similar-sized but much less subtle fruit flies as they shove off in search of another banana. And even on a full stomach, these bloodsuckers are stunningly fast, says Muijres. "So takeoff phase takes only about 30 milliseconds, which is 10 times faster than how fast we can blink our eye." And they're gone before we know what hit us. And before we can hit them.

1. What does the passage mainly talk about?

A．How mosquitoes get nutrients for their developing eggs.

B．How mosquitoes can find their suitable blood donors

C．How mosquitoes escape undetected after sucking blood.

D．How the female mosquitoes find their perfect partners.

2. What plays the most important part in helping mosquitoes escape?

A．Their legs

B．Their ears

C．Their mouths

D．Their wings

3. Mosquitoes’ takeoff approach is different from that of most other winged insects in that________.

A．mosquitoes are lighter than them

B．mosquitoes are keen on sucking blood

C．mosquitoes take off first with wings and then legs

D．mosquitoes take off through the aerodynamic forces

4. From what Muijres said, we know that mosquitoes’ escape speed is _________.

A．extremely fast	B．equal to that of our blink
C．faster than that of fruit flies	D．greatly affected by their full stomach

10 . 31stOctober —— A team of British explorers has announced they are going to the North Pole to measure the ice cap’s thickness. The exploration will take ground-based readings (仪表的读数) of an ice formation which most scientists agree is shrinking at an alarming rate.

Explorer Pen Hadow’s three-member team will pull a sled-fixed radar device, which measures ice density every eight centimeters, 2,000 kilometers across the Arctic and will produce millions of readings.

They will leave in February, 2008 and will face temperatures of -50℃ on a journey that will take up to 120 days. They have been testing their equipment in Britain and Canada.

Hadow is excited about the prospects (前景), “For the first time we will be able to transmit video images — webcam film of the expedition — as it unfolds so people can track us, and the whole idea is to engage as many people as we can in what we’re doing.”

New fallen snow on top of the ice makes ground-based measurements more accurate than satellite data.

“It has been in the planning stage for a while,” said Hadow. “We spent the last two years developing impulse radar (冲击雷达), which normally is about 100 kilograms and hangs under an aircraft and so on. We’ve managed to get it down to about 4 kilograms. It’s the size of a briefcase and we are dragging it behind the sled as we go.”

The ice cap shrank enough in 2007 so that a pathway through the cap known as the Northwest Passage opened up during the melting of the Arctic summer.

Cambridge University’s Joao Rodrigues explains, “Thickness of the ice cap will determine how much solar radiation will be reflected and the heat exchange between the ocean and the atmosphere and it is thus a vital component (成分) of climate models.”

If warming trends continue, some experts predict that the Arctic Ocean could be ice-free during the summer within a few decades.
