Sight
Butterflies have large, compound (multifaceted) eyes, which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a large stand of flowers rather than individual plants. Butterflies do not "see" colors such as red, green, and yellow, but sense polarized(偏振的) light, which indicates the direction the sun is shining, as well as ultraviolet light, which is present on many flowers and guides butterflies to nectar (花蜜)sources.
Smell
Butterflies have a very well-developed sense of smell, but it"s not in their nose (since they don"t have one). Sense receptors located in their antennae, feet, and many other parts of the body help butterflies find food (usually flower nectar), and mates (the female smells the male"s pheromones).
Taste
Butterfly"s feet have sense organs that can taste the sugar in nectar, letting the butterfly know if something is good to eat or not. Some females also taste host plants in order to find appropriate places to lay their eggs. Adult butterflies and moths feed using a proboscis, a long, coiled tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.
Hearing
Butterflies don"t have ears. Instead they "hear" sounds through their wings by sensing changes in sound vibrations.
Butterflies may possess senses we don"t even know about yet because their anatomy is very different than ours, and therefore difficult to understand when perceived through our own human senses.

A.thing behind them | B.thing in the distance |

举一反三
Elizabeth Taylor was born in London in 1932. Her parents, both Americans, had moved there for business reasons. When World War II started, the Taylors moved to Beverly Hills, California, and there Elizabeth started acting in movies. After her success as a child star, Taylor had no trouble moving into adult(成人)roles and won twice for Best Actress: Butterfield 8(1960) and Who’s Afraid of Virginia Woolf ? (1966)
Taylor’s fame(名声)and popularity gave her a lot of power with the movie industry, so she was able to demand very high pay for her movies. In 1963, she received $1 million for her part in Cleopatra—the highest pay received by any star up to that time.
Elizabeth Taylor is a legend (传奇人物) of our time. Like Velvet Brown in National Velvet, she has been lucky, she has beauty, fame and wealth. But she is also a hard worker. Taylor seldom acts in movies any more. Instead, she puts her time and efforts into her businesses, and into helping others — several years ago, she founded an organization that has raised more than $40 million for research and education.
小题1: The producers didn’t let Taylor play the part of Velvet at first because they thought she ____.
A.was small in size | B.was too young |
C.did not play well enough | D.did not show much interest |
A.popular all their lives | B.famous actresses |
C.suecessful when very young | D.rich and kind-hearted |
A.12 | B.28 | C.31 | D.34 |
A.doing business and helping others | B.turning herself into a legend |
C.collecting money for the poor | D.going about research and education work |
Appreciate the Person.
Most Americans like to be recognized as individuals as someone special with unique personalities. Therefore, never say, “You’re from America so I want to be your friend.” Also don’t imply that the reason why you approached them is that you wanted someone to practice your English with. That turns people off. Instead try saying,” You seem like a real nice and interesting person and I would like to get to know you better.” This way, they are much more inclined to be friendly because you see them as a three dimensional person and appreciate them for who they are in the inside. And by doing so, you not only learn about Americans and practice your English, but also gain a real friend in the process.
Quit Calling Us Foreigners.
Please avoid calling a foreigner a foreigner especially in his face. The word makes people feel like an outsider, and even unwelcome, suggesting separation and insurmountable differences, widening an already existing gap in the situation. When Americans travel, they rarely say, “ I’m foreign to your place.” They tend to say, “ I’m new in town. I’m new here.” The reason is because new and unfamiliar things can become old and familiar. But can foreign things become native? Aha? You catch my drift.
Just Do It.
Some students like to be told about American culture but are less interested in spending the time and the effort to actually experience it. As Americans always say, “ Get your hands dirty.” You should have first hand and hands on experience, or you’ll never really know anything.
Find that Common Language.
Now I must stress the importance of finding a common language. By that I don’t mean English, Chinese, German, French, etc. I mean finding something you have in common with another person on a spiritual and philosophical level: likes, dislikes, worldviews, ways of thinking , and attitudes toward life. And to start, you must first enhance your knowledge of the particular culture from which your potential new friend comes form.
小题1:The underlined sentence “ Get your hands dirty” means .
A.get involved | B.start with dirty work |
C.talk about American culture | D.don’t wash your hands too often |
A.avoid talking about their homeland |
B.recognize their personalities |
C.obey rules of communicating with friends |
D.needn’t practice English while playing together |
A.I am longing to make friends with an American. |
B.This is my friend Tom, who is a foreigner. |
C.There must be a gap between us in many things. |
D.You’ve got a great personality. |
When you are happy,little unpleasant events usuallv do not disturb you.When you are unhappy,you feel as if everything is against you.You may compensate for it by eating chocolate and sweets because this gives you pleasure,yet you stay unhappy.A person may smoke cigarettes because it gives him pleasure,yet this does not make him happier,especiallv if he knows the fact that it is not good for his heahh.
The physical world is always in a changing state.At each moment a new thing is being created,changed,transformed and then destroyed.This is the normal state of things and no one can change it.If we stay still in a certain state,we are sure to experience unhappiness sooner or later.0n the other hand, if
we adjust to the environment,nothing can influence our moods.Then outer events have nothing to do with our inner joy of mind.
The room of the mind is filled with worry or fear.If you are free of thinking about them,the room has been emptied,and then you will see what is happening and experience it.When your mind stays quiet,you will see that happiness comes from the inside.

A.A friend gives you a glass of cold lemonade when you feel thirsty. |
B.You eat chocolate and sweets when you feel as if everything is against you. |
C.Smoke cigarettes even though you know the fact that it is not good for your health. |
D.You are free from worry or fear when your mind stays quiet. |
A.happiness is more dependent on the five senses |
B.pleasure sometimes arouses happiness |
C.you feel happy when nothing around you changes in a certain state |
D.you feel unhappy because you have to adjust to the environment |
A.Pleasure Leads to Happiness |
B.Happiness Changes Us |
C.Happiness Is Within Us |
D.Stay a Quiet Mind |
Most people in the working class have at least high school education. Many have some experience of college(especially community college), though few are college graduates. Unionization has helped the working class, but a rapidly changing economy and frequent periods of high unemployment make it difficult for most of its members to be able to increase their savings greatly. Purchasing a house for people in this class is extremely difficult, although a certain percentage may receive houses from their parents. (Home-owning rises with social class.)
A greater number of the members of the working class take relatively little satisfaction in their jobs, because much of their work is ordinary and boring. As a result, many seek their main satisfaction in recreational activities. Many members of this class would like to earn enough money to leave their jobs and start their own businesses, though few make it. Many place their expectations on their children, hoping that they at least will rise in the ladder of success.
小题1: Which of the following is true about the working class?
A.They are often offered jobs with high incomes. |
B.They are employed as skilled and semi-skilled workers. |
C.They are often considered lazy and dishonest. |
D.They are often exploited by the public. |
A.have bad effects on | B.break up |
C.beat | D.strike with a blow |
A.have at least some experience of college |
B.receive houses from their parents |
C.buy houses by themselves |
D.have difficulty increasing their savings greatly |
A.they are not interested in their jobs. |
B.they could not earn much money |
C.they are not their own bosses |
D.they could not rise in the ladder of success |
Even if you don’t have a timepiece of some sort nearby, your body keeps its own beat. Humans have an internal clock that regulates(调节) the beating of our heart, the pace of our breathing, the discharge(排出) of chemicals within our bloodstream, and many other bodily functions.
Time is something from which we can’t escape. Even if we ignore it, it’s still going by, ticking away, second by second, minute by minute, hour by hour. So the main issue in using your time well is, “Who’s in charge?” We can allow time to slip by and let it be our enemy. Or we can take control of it and make it our ally.
By taking control of how you spend your time, you’ll increase your chances of becoming a more successful student. Perhaps more importantly, the better you are at managing the time you devote to your studies, the more time you will have to spend on your outside interests.
The aim of time management is not to schedule every moment so we become slaves of a timetable that governs every waking moment of the day. Instead, the aim is to permit us to make informed choices as to how we use our time. Rather than letting the day go by, largely without our awareness, what we are going to discuss next can make us better able to control time for our own purposes.
小题1: The underlined word “ally” in Para.3 most likely means somebody or something that is ___.
A.your supporter and helps you | B.under your control and obeys you |
C.under your influence and follows you | D.your slave and serves you |
A.could be managed by the internal clock of human bodies |
B.should be well managed for our own interest |
C.should be saved for outside interests |
D.could be regulated by a timepiece such as a clock or a watch |
A.how to make up for lost time | B.how to have a good time |
C.how to make good use of time | D.how to keep up with the times |
