First, let's talk about culture. The difference between the mobile phone and its parent, the fixed-line phone, you get whoever answers it.
This has several implications. The most common one, however, and perhaps the thing that has changed our culture forever, is the "meeting" influence. People no longer need to make firm plans about when and where to meet. Twenty years ago, a Friday night would need to be arranged in advance. You needed enough time to allow everyone to get from their place of work to the first meeting place. Now, however, a night out can be arranged on the run. It is no longer "see you there at 8", but "text-me around 8 and we'll see where we all are".
Texting changes people as well. In their paper, "Insights into the Social and Psychological Effects of SMS Text Messaging", two British researchers distinguished between two types of mobile phone users: the "talkers" and the "texters"--those who prefer voice to text message and those who prefer text to voice.
They found that the mobile phone's individuality and privacy gave texters the ability to express a whole new outer personality. Texters were likely to report that their family would be surprised if they were to read their texts. This suggests that texting allowed texters to present a self-image that differed from the one familiar to those who knew them well.
Another scientist wrote of the changes that mobiles have brought to body language. There are two kinds that people use while speaking on the phone. There is the "speakeasy": the head is held high, in a self-confident way, chatting away. And there is the "spacemaker': these people focus on themselves and keep out other people.
Who can blame them？ Phone meetings get cancelled or reformed and camera-phones intrude on people's privacy. So, it is understandable if your mobile makes you nervous. But perhaps you needn't worry so much. After all, it is good to talk.
When people plan to meet nowadays, they ______.
A．arrange the meeting place beforehand
B．postpone fixing the place till last minute
C．seldom care about when and where to meet
D．still love to work out detailed meeting plans
New "fake fat" products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate. Critics, however, say the new compound can rob the body of essential vitamins and nutrients (营养物) and can also cause unpleasant side effects in some people. So it's up to consumers to decide whether the new fat-free products taste good enough to keep eating.
Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can't be digested at all.
Normally, special chemicals in the intestines(肠)"grab" molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatting acids.
The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.
Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broke down. Manufacturers say it's the ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular at without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E and K from being absorbed. It can also prevent the absorption of carotenoids(类胡萝卜素), compounds that may reduce the risk of cancer, heart disease, etc.
Manufacturers are adding vitamins A, D, E and K as well as carotenoids to their products now. even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming.
We learn from the passage that olestra is a substance that______.
A．contains plenty of nutrients
B．renders foods calorie-free while retaining their vitamins
C．makes foods easily digestible
D．makes foods fat-free while keeping them delicious

【参考答案分析】：
Due Attention Should Be Given To Spelling
Correct spelling is a basic skill in English study. However, nowadays many students do not pay much attention to it.
They have their own reasons for misspelling. First of all, they like an easy way of studying, which causes some omissions and changes in spelling. Second, the teachers might not be very strict in students’ spelling. In China, teachers seem to be more concerned with grammar and vocabulary but not spelling.
To change this situation, in my opinion, the teachers and the students should work together. On one and, the teachers should give more attention to students’ spelling, asking the students to be conscious of the importance of correct spelling from the very beginning of their English study. On the other hand, the students themselves are supposed to be aware that correct spelling is a must in English study.
To sum up, correct spelling is so important that both students and the teachers should spare no efforts to achieve correct spelling.

听力原文： Ask the average American,"What is freedom？"You will probably hear,"It's being able to do what I want to do." When Americans think of freedom, they often think of individualism.They see themselves more as individuals than as members of a family or social group.
In American culture.freedom means equality.The Declaration of Independence states that"all men are created equal."That does not mean equal in abilities or status.For Americans,equality refers to equal worth and equal opportunity. Every individual should have an equal chance to improve his life.True,America has not always lived up to that ideal.For many years,Native Americans,African Americans and immigrants have protested their unequal treatment. But American culture still teaches that people can work hard and fulfill their dreams.Whether this idea is true or not,people hear rags-to-riches stories often enough to confirm it in the minds of many people.
Freedom arouses strong feelings for Americans.The idea of liberty binds people together in this"land of the free." However,problems still exist.One individual's freedom can conflict with the rights of others. Someone once said,"You have the freedom to swing your fist around if you want.But your freedom ends where my nose begins."People can also become too concerned about their own rights.They might demand special treatment.However,the path to freedom is not completely smooth.Even so,for Americans,no other road is really worth traveling.
What do Americans often think of when thinking of freedom？
A．Collectivism.
B．Equality.
C．Social group.
D．Individualism.
