    As is known to all, many things can be measured in terms of data. Sometimes data can indeed tell the truth. With the help of data we can easily know the price of a can of Coke in the supermarket or the result of a football match. 1______ What is more important, data seem to be fairer than words or statements. If the data are true, we don’ t have to worry about being cheated. Nowadays, as lies exist in the world, data are expected to tell the truth. Therefore, many of us would rather believe data.
    On the other hand, if we judge things only by data from the so -called specific research, aren’t we a little too narrow-minded? Many people often treat the so -called specific data unwisely just to make sure that they are making the right decisions. 2_____For example,how can you tell that somebody isn’t a good student just because he or she doesn’t get high marks in the final examination?
    3______ For example,the degree of your feeling happy in your life,the depth of love between you and your friends, and the faith you have in your country. We can only feel them in our hearts but can never express them in data.
    There is no doubt that analyzing the exact data is important to assessment of an actual event. But data should be dealt with wisely. We often get wrong data which mislead us. 4_____Remember, data have no feeling but we humans have. Data do not mean much to people if we do not have the abilities to analyze the data with the knowledge and confidence to judge whether they are true or false. 5______
    Data are data after all. Life is much more colorful than the pale data. So give the cold data a warm heart and we’ 11 find that the world is far more wonderful than the pale data can describe.
    A. We should try our best to be wise thinkers.
    B. Data can make our life easier and more comfortable.
    C. But sometimes we may find that data aren’t everything.
    D. Sometimes our hearts and mind are more sensitive than data.
    E.      Now and then the so-called specific data puzzle us very much.
    F.      The exact data should come from assessment of an actual event.
    G.     There are many things in our life which cannot be measured by data.

③十位整数序数词的构成方法是将基数词的词y变成i,然后再加eth。

④两位或两位以上的基数词变成序数词时,仅将个位数变成序数词。
