(2019·赣州质检)With the everincreasing popularity of online shopping，users' reviews are becoming more and more important.Given that you can't actually touch，see，smell or hear the product you're buying online，these reviews will provide you with valuable information on the product itself.But how far can you trust them?
Barnaby Bicken had an unpleasant experience.“I took some friends to a restaurant in Manchester that had excellent reviews on a food website.However，the service was awful and we were ignored most of the time.Later，I wrote a review on the same site only to be told that the review site owner would not accept any bad reviews—only the good ones.”
So，how can you get a useful review？Web expert Hilary Saunders has a few top tips.“If there are only a few reviews of a place，there is a good chance they have been planted by friends or enemies.If there are many reviews，start by dropping the most extreme comments.Also，watch out for similarities in style between reviews from people with different usernames，particularly if those reviews were placed about the same time.The best thing is to look for reviewers who show some relevant knowledge of the product they are reviewing.”
Some companies seem to be contributing to the problem.A publishing house offered gift vouchers(购物礼券) to anyone who would give their textbook a fivestar review.But not all online companies operate like this.“Amazon works hard to keep the completeness of its customer reviews，”said a spokesperson for the company.“We have very clear guidelines，and when a customer reports a review that he feels is inappropriate，we check，and may take it down.”
So，next time you see that fivestar review for something you want to buy，be aware—it could be the work of a false reviewer!
【语篇解读】 本文是一篇说明文，主要介绍了随着网上购物越来越受欢迎，使用者的评价变得越来越重要。但是，这些评价的可信度到底有多高呢？
1．What does“them”in Para.1 refer to?
A．Products. B．Users.
C．Reviews. D．Buyers.
C [代词指代题。them指代上文中的名词复数形式，上文的复数名词有reviews和buyers，再根据下文的关于网上评价未必都和事实相符的例子可知，这里应选C项。]
2．What does Barnaby Bicken's story imply?
A．The food served was awful.
B．Not all reviews are believable.
C．Many people are easily cheated.
D．He likes to write bad reviews.
B [推理判断题。Barnaby Bicken选择了一家网评很好的饭店吃饭，结果发现饭店的服务质量非常糟糕，自己想如实写一个评论发表，但又不被接受。该例子是对第一段最后一句“这些评论可信度有多高？”的回应，故该例子是说明网上评价未必都和事实相符，因此选B项。]
3．What reviews of products are useful?
A．Those by competitors.
B．Those by different users.
C．Those with good comments.
D．Those with related information.
D [细节理解题。根据文章第三段中的“The best thing is to look for reviewers who show some relevant knowledge of the product they are reviewing”可知，最好是寻找那些对评论的产品有相关知识的网评者，故有相关信息的那些评论是有用的，因此D选项符合题意。]
4．How does Amazon deal with the customer reviews?
A．It helps to finish the reviews.
B．It pays attention to the bad reviews.
C．It offers gifts for the good reviews.
D．It tries to make the reviews objective.
D [推理判断题。根据文章第四段中的“Amazon works hard to keep the completeness of its customer reviews”和“We have very clear guidelines，and when a customer reports a review that he feels is inappropriate，we check，and may take it down”可知，亚马逊公司努力保持顾客评论的完整性，处理顾客所反映的不恰当的评论，因此可以说该公司尽量保持评论的客观性，因此答案为D选项。]
