《合同法》规定的合同变更条件包括（）。
A.有效的合同
B.协商一致
C.合同当事人一方确有变更理由和依据
D.须经合同管理机关批准
E.变更内容明确
参考答案：A, B, E
解析：合同法规定：当事人协商一致，可以变更合同。当事人对合同变更的内容约定不明确的，推定为未变更。 想想我们自己在生活和工作中的常识，只要合法、合规，且符合当事人双方的真实意愿，当事人双方就可在协商一致的条件下订立合同，也可以变更合同（变更内容须明确），无需其他条件，因此可以将C、D二项剔除。
根据短文内容，从下框的A～F选项中选出能概括每一段主题的最佳选项，并将答案写在答题卷指定区域的横线上。选项中有一项为多余项。
1. Don’t choose a rather difficult book or a too easy one for yourself to read. A book full of new words will make you discouraged quickly. To understand these new words, you have to turn to the dictionary quite often. It seems that you are not reading the book but the dictionary. It has no fun at all! On the contrary, a too easy one will only waste your time and cannot do any help. The two extremes may at last make you give up reading. So it’s better for you to find a proper book with no more than five new words on each page. 2. If you come across a new word, do not look it up in a dictionary as quickly as possible. Leave it alone and guess the meaning of it based on the content of the text. This ability is quite necessary in reading. If you know your guess is right later, you will be highly excited at your “success”, and your interest in reading is well stimulated. If a word really hinders you from understanding the whole passage, turn to the dictionary by then. I am sure you can remember this word very well, as it has left you such a deep impression for “its troublesome image”. 3. To comprehend what you are reading, you should think while you are reading, then form your own ideas on some special issues. Try to scribble (乱写；潦草地书写)some lines — a very short journal, to express your ideas. Your writing does not need to be quite formal but expressive. This practice can make you communicate with the original English authors. Day by day, your way of thinking in English will turn into a native way, which is quite important for English writing. 4. Language has its own beauty, no matter Chinese or English. Don’t merely take English as a “test”. Take it as an “entertainment” instead and you will enjoy it through learning. Maybe you should find some beautiful literary works such as a prose or a poem to read, if you like. Try to read them as loudly and passionately as you can. During this process, not only can you enjoy yourself by the great emotions of the writers, but also your pronunciation and your manner of speaking English will be improved. 5. The last but not the least, keep on reading. If you cannot keep it as a habit, you will suffer from paying without gaining. |
