Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda（大熊猫）eats only one particular type of bamboo（竹子）. Other animals eat only one type of food even when given the choice. A kind of white butterfly（蝴蝶）will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet（多样化饮食）. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

A．depend on one sense in choosing food	B． are not satisfied with their food

举一反三

It may help you to know that there is no such thing as a perfect speech.At some point in every speech,every speaker says something that is not understood exactly as he has planned.Fortunately,such moments are usually not obvious(明显的) to the listeners.Why?Because the listeners do not know what the speaker plans to say.They hear only what the speaker does say.If you lose your place for a moment,wrongly change the order of a couple of sentences,or forget to pause at a certain point,no one will be any the wiser.When such moments occur,don’t worry about them.Just continue as if nothing happened.
Even if you do make an obvious mistake during a speech,that doesn’t really matter.If you have ever listened to Martin Luther King’s famous speech—“I Have a Dream”,you may notice that he stumbles(结巴) over his words twice during the speech.Most likely,however,you don’t remember.Why?Because you were fixing your attention on his message rather than on his way of speech-making.
People care a lot about making a mistake in a speech because they regard speech-making as a kind of performance rather than as an act of communication(交流).They feel the listeners are like judges in an ice-skating competition.But,in fact,the listeners are not looking for a perfect performance.They are looking for a well-thought-out speech that expresses the speaker’s ideas clearly and directly.Sometimes a mistake or two can actually increase a speaker’s attractiveness by making him more human.
As you work on your speech,don’t worry about being perfect.Once you free your mind of this,you will find it much easier to give your speech freely.
小题1:The underlined part in the first paragraph means that no one will _______.

A．be smarter than you	B．notice your mistakes
C．do better than you	D．know what you are talking about

小题2:You don’t remember obvious mistakes in a speech because _______.

A．your attention is on the content

B．you don’t fully understand the speech

C．you don’t know what the speaker plans to say

D．you find the way of speech-making more important

小题3:It can be inferred from the passage that _______.

A．giving a speech is like giving a performance

B．one or two mistakes in a speech may not be bad

C．the listeners should pay more attention to how a speech is made

D．the more mistakes a speaker makes,the more attractive he will be

小题4:What would be the best title for the passage?

A．How to Be a Perfect Speaker

B．How to Make a Perfect Speech

C．Don’t Expect a Perfect Speech

D．Don’t Expect Mistakes in a Speech

When people want to know about the weather,they usually go to their radios,TVs, newspapers,or to the Internet.However,you can also find many weather signs among wildlife, because of their highly developed senses.Drops in air pressure(压力) produce an effect on small animals in many ways.Mice and deer are good weather indicators.People who spend a lot of time outdoors have observed that,before a storm,field mice come out of their holes and run around.Deer leave high ground and come down from the mountains.
Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways.For example,some birds become irritable(急躁的) and quarrelsome and will fight over a piece of bread.Other birds chirp(叽叽喳喳) and sing just before a storm.It seems they know they won’t get another chance for an hour or two.Birds also seek safe places before a storm.You will sometimes see birds settling in trees or gathering together on a wire close to a building.Pre-storm low pressure makes the air so thin that birds have difficulty flying.
It is unusual to see many birds flying overhead in the summertime,rather than during the periods in the spring or autumn.Watch for other weather signs if you see this.If they fly in the wrong direction,they may be flying ahead of a storm.
By paying closer attention to some important signs in nature,we can become better prepared for any kind of weather.
小题1:The word “indicators” in Paragraph 1 probably means______.

A．maps	B．services
C．signs	D．stations

小题2:There will be a storm if birds______.

A．make more noise than usual

B．fly in different directions

C．come down from tall trees

D．share a piece of bread

小题3:How can birds sense the coming of a storm?

A．By feeling a drop in air temperature.

B．By noticing the change of wind directions.

C．By feeling a drop in air pressure.

D．By noticing the movements of other animals.

小题4:The best title for the text would be______.

A．Signs of a Storm

Photos that you might have found down the back of your sofa are now big business!
In 2005,the American artist Richard Prince’s photograph of a photograph,Untitled (Cowboy),was sold for $1 248 000.
Prince is certainly not the only contemporary artist to have worked with so-called “found photographs”—a loose term given to everything from discarded(丢弃的)prints discovered in a junk shop to old advertisements or amateur photographs from a stranger’s family album.The German artist Joachim Schmid,who believes “basically everything is worth looking at”,has gathered discarded photographs,postcards and newspaper images since 1982.In his on-going project,Archiv,he groups photographs of family life according to themes:people with dogs;teams;new cars;dinner with the family;and so on.
Like Schmid,the editors of several self-published art magazines also champion(捍卫)found photographs.One of them,called simply Found,was born one snowy night in Chicago,when Davy Rothbard returned to his car to find under his wiper(雨刷)an angry note intended for someone else:“Why’s your car HERE at HER place?”The note became the starting point for Rothbard’s addictive publication,which features found photographs sent in by readers,such as a poster discovered in your drawer.
The whole found-photograph phenomenon has raised some questions.Perhaps one of the most difficult is:can these images really be considered as art?And,if so,whose art?Yet found photographs produced by artists,such as Richard Prince,may raise endless possibilities.What was the cowboy in Prince’s Untitled doing?Was he riding his horse hurriedly to meet someone?Or how did Prince create this photograph?It’s anyone’s guess.In addition,as we imagine the back-story to the people in the found photographs artists,like Schmid,have collated(整理),we also turn toward our own photographic albums.Why is memory so important to us?Why do we all seek to freeze in time the faces of our children,our parents,our lovers,and ourselves?Will they mean anything to anyone after we’ve gone?
In the absence of established facts,the vast collections of found photographs give our minds an opportunity to wander freely.That,above all,is why they are so fascinating.
小题1:The first paragraph of the passage is used to_______.

A．remind readers of found photographs

B．advise readers to start a new kind of business

C．ask readers to find photographs behind sofas

D．show readers the value of found photographs

小题2:According to the passage,Joachim Schmid_______.

A．is fond of collecting family life photographs

B．found a complaining note under his car wiper

C．is working for several self-published art magazines

D．wondered at the artistic nature of found photographs

小题3:The underlined word “them”in Paragraph 4 refers to“_______”.

A．the readers

B．the editors

C．the found photographs

D．the self-published magazines

小题4:By asking a series of questions in Paragraph 5,the author mainly intends to indicate that_______.

A．memory of the past is very important to people

B．found photographs allow people to think freely

C．the back-story of found photographs is puzzling

D．the real value of found photographs is questionable

小题5:The author’s attitude toward found photographs can be described as_______.

A．critical	B．doubtful
C．optimistic	D．satisfied

Host family accommodation,or living with host families,remains popular among language travel students for its unique advantages.These days,host families are trying to offer more in terms of quality,for they still have something to worry about.
Host family accommodation is often seen as the number-one choice for its advantages in language study,cultural communication and cost of living.Staying alongside host families enables students to get enough practice for the short time of their studying so that their language acquisiton is likely to become faster.Living in host families also has the advantage of students of being able to spend a lot of time communicating with their “host parents”,and get to know the local way of life,people and culture.Another advantage is that host family accommodation can sometimes be the least expensive.It attracts students for it ensures them a family type of living at a low cost.
The advantages,however,have not prevented host families from worrying.On one hand,some host families are losing their unique selling point.The probelm is that the majority of bosts in big cities,now generally single and young,have less time available for students,but the selling point for host family accommodation is communication practice.On the other,students’ expectations have risen.They are becoming more demanding and asking for more than ever from their accommodation,as they come mainly from high socio-economic groups in their own countries.
To get out of the difficult situation,host families are now making efforts to improve the quality of service.They are trying to make living conditions better,including broadband Internet service,private bathroom,and access to plenty of hot water for long showers.They are also providing students with structured family activities.
It is believed that host family accommodation will keep the popularity vote with language travel students.
