Can you imagine a world without chocolate? It's not something I'd 1ike to do．so I was relieved to read that there’s a university with a program me to safeguard the future of chocolate!
The University of Reading，in England，has just opened a new clearing house for all the world’s new cocoa varieties．They must be quarantined(隔离检疫)before they can be grown．Why? Cocoa production hit a record high of 4．4 million tons last year but about 30％of the precious crop is regularly lost to pests and diseases．Now we don’t want that，do we?
Demand for chocolate has been increasing faster than the world supply of cocoa and researchers think that new varieties are key to solving this problem．
The University of Reading has been protecting the quality of the new crops since 1985，after it took over the task from the Royal Botanical Gardens in Kew，London．And it has improved its facilities．The leader of the institution’s cocoa project，Professor Paul Hadley，says，“One of the main issues concerning cocoa improvement is the supply of reliably clean，healthy，interesting cocoa material．”
The cocoa centre has a collection of 400 plant varieties and their greenhouse uses a lot of energy to keep them in tropical conditions．After up to two years in quarantine，clean and safe seeds are sent to some 20 countries，including several in West Africa．That’s where 75％of the cocoa used for chocolate worldwide comes from．The crop is extremely important for the local economy：it employs about two million people.
Professor Hadley says he works with a small team of skilled technicians who look after the collection．And more of us seem to count on them now．
The scientist says，“there is some concern within the industry that demand is increasing constantly，particularly in countries like China，where the standard of living is increasing and people are getting a taste for different chocolates．”

Professor Barry Wellman of the University of Toronto in Canada has invented a term to describe the way many North Americans interact(互动)these days.The term is “networked individualism”.This concept is not easy to understand because the words seem to have opposite meanings.How can we be individuals(个体)and be networked at the same time?You need other people for networks.
Here is what Professor Wellman means.Before the invention of the Internet and e-mail,our social networks included live interactions with relatives,neighbors,and friends.Some of the interaction was by phone,but it was still voice to voice,person to person,in real time.
A recent research study by the Pew Internet and American Life Project showed that for a lot of people,electronic interaction through the computer has replaced this person-to-person interaction.However,a lot of people interviewed for the Pew study say that’s a good thing.Why?
In the past,many people were worried that the Internet isolated(孤立)us and caused us to spend too much time in the imaginary world of the computer.But the Pew study discovered that the opposite is true.The Internet connects us with more real people than expected—helpful people who can give advice on careers,medical problems,raising children,and choosing a school or college.About 60 million Americans told Pew that the Internet plays an important role in helping them make major life decisions.
Thanks to the computer,we are able to be alone and together with other people—at the same time!The underlined phrase “networked individualism”probably means that by using computers people_______.
| A．stick to their own ways no matter what other people say |
| B．have the rights and freedom to do things of their own interest |
| C．do things in their own ways and express opinions different from other people |
| D．are able to keep to themselves but at the same time reach out to other people |
According to the Pew study,what do many people rely on to make major life decisions?
| A．Networks. | B．Friends. |
| C．Phones. | D．Parents. |
It can be inferred from the Pew study that_______.
| A．people have been separated from each other by using computers |
| B．the Internet makes people waste a lot of time and feel very lonely |
| C．the Internet has become a tool for a new kind of social communication |
| D．a lot of people regard the person-toperson communication as good thing |
Which would be the best title for this passage?
| A．We’re Alone on the Internet. |
| B．We’re Communicating on the Internet. |
| C．We’re Alone Together on the Internet. |
| D．We’re in the Imaginary World of the Internet. |
Su Hua is studying at Cambridge,UK.She has bought a bicycle and is worried about security(安全).Her friend,Kate,found this article and sent it to her.
| Introduction A lot of crime is against bicycles.About 150 000 bicycles are stolen every year and most are never found.You can prevent this happening by following a few careful steps. Basic Security Do not leave your bicycle in out-of-the-way places.Always lock your bicycle when you leave.Secure it to lampposts or trees.Take off smaller parts and take them with you,for example lights and saddles(车座). Locks Get a good lock.There are many different types in the shops.Buy one that has been tested against attack.Ask for a recommendation from a bike shop. Marking Security making your bike can act as a deterrent to a thief.It can also help the police find your bicycle.It should be clearly written and include your postcode and your house or flat number.This will provide a simple way to identify your bicycle. Registration There are a number of companies who will security mark your bicycle for you.They will then put your registration number and personal details on their computer database.Then if your bicycle is found it will be easy to contact you. Finally Keep a record of the bicycle yourself:its make,model and registration number.You can even take a photograph of it.This will prove the bicycle belongs to you. |

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.

All her life,my mother wanted busy children.It was very important that her house should remain at all times clean and tidy.
You could turn your back for a moment in my mother's house,leave a half-written letter on the dining room table,a magazine open on the chair,and turn around to find that my mother had "put it back where it belonged,"as she explained.
My wife,one of her first visits to my mother's house,placed a packet of biscuits on an end table and went to the kitchen to fetch a drink.When she returned,she found the packet had been removed.Confused(疑惑的),she set down her drink and went back to the kitchen for more biscuits,only to return to find that her drink had disappeared.Up to then she had guessed that everyone in my family held onto their drinks,so as not to make water rings on the end tables.Now she knows better.
These disappearances had a confusing effect on our family.We were all inclined to(有……的倾向) forgetfulness,and it was common for one of us,upon returning from the bathroom,to find that every sign of his work in progress had disappeared suddenly."Do you remember what I was doing?"was a question frequently asked,but rarely answered.
Now my sister has developed a second-hand love of clean windows,and my brother does the cleaning in his house,perhaps to avoid having to be the one to lift his feet.I try not to think about it too much,but I have at this later time started to dust the furniture once a week.
We have all become busy persons.
