     Almost every day we come across situations in which we have to make decisions one way or 

another. Choice, we are given to believe, is a right. But for a good many people in the world, in rich and 

poor countries, choice is a luxury, something wonderful but hard to get, not a right. And for those who 

think they are exercising their right to make choices, the whole system is merely an illusion, a false idea 

created by companies and advertisers hoping to sell their products.      

    The endless choice gives birth to anxiety in people's lives. Buying something as basic as a coffee pot is 

not exactly simple. Easy access to a wide range of everyday goods leads to a sense of powerlessness in 

many people, ending in the shopper giving up and walking away, or just buying an unsuitable item (商品 ) 

that is not really wanted. Recent studies in England have shown that many electrical goods bought in 

almost every family are not really needed. More difficult decision-making is then either avoided or trussed 

into the hands of the professionals , lifestyle instructors, or advisors.      

    It is not just the availability of the goods that is the problem, but the speed with which new types of 

products come on the market. Advances in design and production help quicken the process. Products 

also need to have a short life span so that the public can be persuaded to replace them within a short 

time. The typical example is computers, which are almost out-of-date once they are bought. This indeed 

makes selection a problem. Gone are the days when one could just walk with ease into a shop and buy 

one thing; no choice, no anxiety. 

1. What does the author try to argue in Paragraph 1 ?     

A. The exercise of rights is a luxury.     

B. The practice of choice is difficult.     

C. The right of choice is given but at a price.     

D. Choice and right exist at the same time.

2. Why do more choices of goods give rise to anxiety?     

A. Professionals find it hard to decide on a suitable product.     

B. People are likely to find themselves overcome by business persuasion.     

C. Shoppers may find themselves lost in the broad range of items.     

D. Companies and advertisers are often misleading about the range of choice.

3. By using computers as an example, the author wants to prove that     

A. advanced products meet the needs of people     

B. products of the latest design flood the market     

C. competitions are fierce in high-tech industry     

D. everyday goods need to be replaced often

Animal studies are under way, human trial protocols are taking shape and drug makers are on alert. All the international health community needs now is a human vaccine for the bird flu pandemic sweeping a cluster of Asian countries.

The race for a vaccine began after the first human case emerged in Hong Kong in 1997. Backed by the World Health Organization (WHO), three research teams in the US and UK are trying to create a seed virus for a new vaccine. Their task is formidable, but researchers remain optimistic." There are obstacles, but most of the obstacles have been treated sensibly," says Richard Webby, a virologist at St. Jude Children’s Research Hospital in Memphis, Tennessee.

The biggest challenge is likely to be the rapidly mutating virus. Candidate vaccines produced last year against the H5N1 virus are ineffective against this year’s strain. Scientists will have to constantly monitor the changes and try to tailor the vaccine as the virus mutates. They can’t wait to see which one comes next.

The urgency stems from fears that I-ISN1 will combine with a human flu virus, creating a pathogen(病原体) that could be transmitted from person to person. But if people have no immunity to the virus, the strain may not mutate as rapidly in people as it does in birds.

To quickly generate the vaccine, researchers are using reverse genetics, which allows them to skip the long process of searching through reassorted viruses for the correct genetic combination. Instead, scientists clone sequences for hemagglutinin(红血球凝聚素) and neuraminidase(神经氨酸苷酶), the two key proteins in the virus. The sequences are then combined with human influenza genes to create a customized reference strain.

Because products developed with reverse genetics have never been tested in humans, the candidate vaccines will first have to clear regulatory review. In anticipation, the US Food and Drug Administration (FDA) and the European Agency for the Evaluation of Medicinal Products (EMEA) are both preparing pandemic response plans. The EMEA has produced a fist-track licensing program, an industry task force and detailed guidance for potential applicants.

In Europe, a reassortant influenza virus -- but not the inactivated vaccine -- produced by reverse genetics would be considered a genetically modified organism, and manufacturers would need approval from their national or local safety authorities. The WHO has prepared a preliminary biosafety risk assessment of pilot-lot vaccine, which could help speed up the review.

A preliminary version of their protocol calls for several hundred subjects, beginning with a group of young adults and gradually expanding to include those most susceptible to the flu -- children and the elderly." If we had product," says Lambert," it would probably be a couple of months at the earliest before we have early data in healthy adults.

What is the author’s attitude towards the newly developed bird flu vaccine（）

A. Slightly approves of

B. Depicts neutrally

C. Slightly disapproves of

D. Completely rejects
