左右两个电路都是从左端输入信号，从右端输出信号.图18-3-11中输入的是高频、低频混合的交流信号，要求只输出低频信号；图18-3-12中输入的是直流和低频交流的混合信号，要求只输出低频交流信号.那么C1、C2中哪个该用大电容？哪个该用小电容？               图18-3-11                   图18-3-12When you are learning English, you find it not clever to put an English sentence, word for word, into your own language. Take the sentence “How do you do?” as an example. If you look up each word in the dictionary, one at a time, what is your translation(翻译)？It must be a wrong sentence in your own language.Languages do not just have different sounds, they are different in many ways. It’s important to master(掌握) the rules for word order in the study of English, too. If the speakers put words in a wrong order, the listener can’t understand the speaker’s sentence easily. Sometimes when the order of words in an English sentence is changed, the meaning of the sentence changes, But sometimes the order is changed, the meaning of the sentence doesn’t change. Let’s see the difference between the two pairs of sentences.“She only like apples.” “Only she likes apples.”“I have seen the film already.” “I have already seen the film.”When you are learning English, you must do your best to get the spirit(精神实质) of the language and use it as the English speaker does.1.From the passage we know that when we are learning English.A. we shouldn’t put every word into our own languageB. we should look up every word in the dictionaryC. we need to put every word into our own languageD. we must read word by word2.We can learn from the passage that .A. the meaning of an English sentence always changes with the order of the wordsB. the order of words can never change the meaning of an English sentenceC. sometimes different order of words has a different meaningD. if the order of words is different, the meaning of a sentence must be different3.“She only likes apples.” means .A. is the same as “Only she likes apples.”B. is different from “Only she likes apples.”C. means “She likes fruit except apples.”D. means “She doesn’t like apples.”4.Which is the best title for this passage?A.
