1.Which of the following could be William Wordsworth’s preference for the language in poetry writing?A.local dialectB.decorumC.the language of the common peopleD.archaic words

2.Passage FiveIn every language there are two great classes of words which, taken together, consist of the whole vocabulary. First, there are those words with which we become acquainted in daily conversation, which we learn, that is to say, from the members of our own family and from our familiar associates, and which we should know and use even if we could not read or write. They concern the common things of life, and are the goods in trade of all those who speak the language. Such words may be called "popular", since they belong to the whole people; and are not the exclusive possession of a limited class.On the other hand, our language includes a large number of words which are comparatively seldom used in ordinary conversation. Their meanings are known to every educated person, but there is little occasion to use them at home or in the market-place. Our first acquaintance with them comes not from our mother's lips or from the talk of our school-mates, but from books that we read, lectures that we bear, or the more formal conversation of highly educated speakers who are discussing some particular topic in a style. raised above the habitual level of everyday life. Such words are called "learned". And the distinction between them and "popular" words is of great importance to a right understanding of the language.51. One class of words can be learned ______.A. through everyday lifeB. without too much practiceC. from popular songsD. with a dictionary in one's hand

    正确答案： A,C
    解析： 在java中一个类只能有一个直接父类，但是可以实现多个接口，在继承的同时可以实现接口，之所以取消多继承的原因是多继承使得代码产生很多问题,而使用单一继承则可以使代码更可靠。
