第五部分（满分25分） Possible version one:
As a major channel of consumption information, the rating is an efficient source of
information for shopping in our own consumption. Interestingly, the same rating may have different influences on different consumers.
I tend to consult consumption ratings whatever I purchase. Firstly, the higher rating means
the higher quality of the product, or better service. Based on the ratings, I bought my beloved backpack, saw interesting films and tasted delicious foods. Secondly, ratings can save time to make decisions in shopping. For example, there are huge amounts of reference books which I am often confused to choose from. In that case, it is both convenient and economical to buy books according to the ratings.
There is no doubt that it is unwise to depend completely on the ratings in consumption. The
advantages and disadvantages of ratings are often closely related. It is necessary to hold an objective attitude towards ratings. Possible version two:
Nowadays, most commodities or services are rated through certain channels. These ratings,
easy to access, are playing an increasingly important role in customers' purchase decision. However, results are sometimes unsatisfactory.
There is no denying that such ratings might bring convenience to consumers, but they are
often misleading and unreliable. As we all know, most of the ratings are based on others’ judgment on the product or service concerned. Every judgment comes from a specific need or a unique psychological state. Apparently, blindly following others' advice will affect our own judgment. Another fact should not be neglected that some of the ratings are the outcome of a careful manipulation of companies or sellers. It has become a common practice for some to pay for good ratings on their products or services so as to increase their sales.
Therefore, we should give a second thought to these ratings whenever we go shopping.
