Love or Hate?
We have saved as a final set of emotions to two most important emotions connected with other people:love and its opposite,hate.Love can be seen everywhere.Yet surprisingly,love has been the subject of less scientific research than other emotions,such as anger and fear. The reason for this may be two fold.Firstly,love is a very complex emotion,difficult to describe and measure. Secondly,unlike many radical emotions,radical love is generally not a problem. Thus less medical attention has been paid to it.
What is love?This is a complex question and requires a complex answer. Love is a strong,positive attraction and feeling for another person or thing. But it is more than this.It also involves feeling of caring,protection,excitement,and tenderness.When two people are in love,they feel drawn to one another;they greatly enjoy each other's company;and they may be sexually attracted to one another.
Sometimes it is easier to think in terms of different kinds of love:romantic love,brotherly love, and so forth.Though they are different in some respects,they share one important characteristic: a strong positive feeling toward another.
Our feelings toward other people are often complex.We may love someone and,at the same time,be angry with him.Or we may love someone,even though we are jealous of him.We mighi even love someone and,at the same time,hate for some precise reason.
Hate is a strong negative emotion toward someone,and is due to anger,jealousy,or some other factor. Like love,hate can be a very strong emotion.It can also be very dangerous.The question is often asked,"Is it bad to hate?"The best answer is probably" sometimes yes and sometimes no." Usually hate does not help us.It makes us feel unhappy and makes us do things that may hurt others.However,sometimes it may be necessary to hate and hurt someone in order to protect loved ones.
According to the passage,hate is caused by___________.
A.anger,jealousy or some other factors
B.anger,danger and hurt
C.caring,protection,excitement and tenderness
D.complex,strong positive emotion

Where Have All the Frogs Gone?
In the 1980s,scientists around the world began to notice something strange:Frogs
were disappearing. More recent research has shown that many kinds of amphibians（两栖
动物）are declining or have become extinct. They have been around for a long time一over
350 million years.Why are they dying out now?
Scientists are seriously concerned about this question.First of all,amphibians are an
important source of scientific and medical knowledge.By studying amphibians,scientists
have learned about new substances that could be very useful for treating human diseases.
Further research could lead to many more discoveries,but that will be impossible if the
amphibians disappear.
The most serious aspect of amphibian loss,however,goes beyond the amphibians
themselves.Scientists are beginning to think about what amphibian decline means for the
planet as a whole.If the earth is becoming unlivable for amphibians,is it also becoming
unlivable for other kinds of animals and human beings as well?
Scientists now believe that amphibian decline is due to several environmental factors.
One of these factors is the destruction of habitat,the natural area where an animal lives.
Amphibians are very sensitive to changes in their habitat.If they cannot find the right
conditions,they will not lay their eggs一These days,as wild areas are covered with
houses,roads,farms,or factories,many kinds of amphibians are no longer laying eggs.
For example,the arroyo toad（蟾蜍）of southern California will only lay its eggs on the
sandy bottom of a slow-moving stream.There are very few streams left in southern
California,and those streams are often muddy because of building projects. Not
surprisingily,the arrovo toad is now in danaer of extinction.
There are a number of other factors in amphibian decline.Pollution is one of them.In
many industrial areas,air pollution has poisoned the rain,which then falls on ponds and
kills the frogs and toads that live there,In farming areas,the heavy use of chemicals on
crops has also killed off arrtphibians.Another factor is that air pollution has led to increased
levels of ultraviolet (UV) light. This endangers amphibians, which seem to be especially
sensitive to UV light. And finally, scientists have discovered a new disease that seems to
be killing many species of arnpttibians in different parts of the world.
All these reasons for the disappearance of amphibians are also good reasons for more
general concern. The destrriction of land, the pollcition of the air and the water, the
changes in our atmosphere, the spread of diseases-these factors affect human beings,
too. Amphibians are especially sensitive to environmental change. Perhaps they are like
the canary （金丝雀）bird that coal miners once used to take down into the mines to detect
poisonous gases. When the canary became ill or died,the miners knew that dangerous
gases were near and their own lives were in danger.
Scientists think that the decline of amphibians could
A.cause environmental change.
B.cause a decline in other kinds of animals.
C.be a warning signal for human beings.
D.be a good sign for human beings.

Bullying at school can have serious and harmful negative effects.Because it causes such a problem for many schools,it is important that schools take the appropriate action to minimize its harmful effects.
One of the most influential steps that a school can take against bullying is to research and develop a firm understanding of the specific types of bullying the students at the school are facing. Administrators should conduct monthly surveys that ask students about their experiences with bullying, such as whether they were bullied in the past month,whether they witnessed bullying and issues that they think the school administrators should have known about. Administrators should also survey the school's teachers to find out what they know about bullying.
Another step that a school administration can take to prevent bullying is to train its teachers, administrators and students' parents about bullying. Hold seminars in your school district to teach parents about ways to communicate with their children if they are bullied at school.Conduct workshops with professional speakers or psychology experts about recognizing the signs of bullying in the classroom for teachers and administrators in your school district.Create newsletters for parents about detail strategies your school is taking to combat bullying or discuss new research on bullying in schools.
Last but not least school administrators,teachers and school board members should work together to create a disciplinary plan to use when situations of bullying arise.Make teachers work together in groups to discuss the strategies that they use for dealing with bullying in their individual classrooms.Developing a plan when bullying arises is important in helping students realize that they will face consequences if they choose to bully their peers.Having a disciplinary system in place can help prevent bullying before it even begins.
Which title is appropriate for the essay?
A.Bullied Students.
B.What Parents Need to Know About School Bullying.
C.Peer Pressure.
D.Strategies Against School Bullying.

第二篇
A Phone That Knows You're Busy
It's a modern problem : you're too busy to be disturbed by incessant（连续不断的）
phone calls so you turn your cellphone off.But if you don't remember to turn it back on
when you're less busy,you could miss some important calls.If only the phone knew when
it was wise to interrupt you,you wouldn't have to turn it off at all.Instead,it could let calls
through when you are not too busy.
A bunch of behavior sensors（传感器）and a clever piece of software could do just
that,by analyzing your behavior to determine if it's a good time to interrupt you.If built into
a phone,the system may decide you're too busy and ask the caller to leave a message or
ring back later.
James Fogarty and Scott Hudson at Camegie Mellon University in Pennsylvania based
their system on tiny microphones,cameras and touch sensors that reveal body language
and activity.First they had to study different behaviors to find out which ones strongly
predict whether your mind is interrupted.
The potential"busyness"signals they focused on included whether the office doors
were left open or closed,the time of day,if other people were with the person in question,
how close they were to each other,and whether or not the computer was in use.
The sensors monitored these and many other factors while four subjects were at work.
At random intervals,the subjects rated how interruptible they were on a scale ranging from
"highly interruptible"to"highly not-interruptible".Their ratings were then correlated with
the various behaviors. " It is a shotgun（随意的）approach: we used all the indicators we
could think of and then let statistics find out which were important,"says Hudson.
The model showed that using the keyboard,and talking on a landline or to someone
else in the office correlated most strongly with how interruptible the subjects judged
themselves to be.
Interestingly,the computer was actually better than people at predicting when someone
was too busy to be interrupted.The computer got it right 82 percent of the time,humans 77
percent.Fogarty speculates that this might be because people doing the interrupting are
inevitably biased towards delivering their message,whereas computers don't care.
The first application for Hudson and Fogarty's system is likely to be in an instant
messaging system,followed by office phones and cellphones. "There is no technological
roadblock（障碍）to it being deployed in a couple of years,"says Hudson.
The computer performed better than people in the study because
A.the computer worked harder.
B.the computer was not busy.
C.people tended to be biased.
D.people were not good at statistics.
