译树版六年级上册英语单元讲解∪nit1 译林版六年级上册英语Unit1《The king's new clothes》单元讲解。
一、单元主题与背景。
本单元围绕《国王的新衣》这个经典故事展开。
这个故事大家应该都不陌生吧，讲的是一个愚蠢的国王被两个骗子欺骗，最后光着身子在众人面前游行的趣事。
通过这个故事，我们不仅能学习英语知识，还能明白一些道理，比如不要轻易相信别人的花言巧语，要保持自己的判断力哦。
二、重点词汇。
在这个单元里，有不少新单词需要我们掌握呢。
比如说：- foolish ：它的意思是“愚蠢的”。
例如：It's foolish of him to believe such a lie.（他相信这样的谎言真是太愚蠢了。
）。
- clever ：表示“聪明的”。
比如：The clever boy solved the problem quickly.（这个聪明的男孩很快就解决了这个问题。
）。
还有很多像这样的单词，大家在学习的时候，可以多造几个句子来加深记忆哦。
三、重点句型。
这部分的重点句型也很实用呢。
- What beautiful clothes! 这是一个感叹句，用来表达对衣服的赞美。
比如说你看到一件特别漂亮的裙子，就可以说：What a beautiful dress!（多么漂亮的裙子啊！）。
- The two men showed the king his new clothes. 这个句子描述了两个男人给国王展示新衣服的情景。
类似的句子我们还可以说：She showed me her new book.（她给我看了她的新书。
）。
大家要多练习这些句型，这样在实际运用中就能更加熟练啦。
四、语法知识。
本单元涉及到一些重要的语法点哦。
- 形容词的用法：形容词一般用来修饰名词，说明事物的特征。
比如“a beautiful flower”（一朵美丽的花），“beautiful”就是形容词，用来修饰“flower”。

Mr. Adams: I’ve often heard people use the term sine wave when discussing AC. What is a sine wave? Engineer: It’s one type of waveform. This waveform graphically represents the time-varying behavior of a sinusoidal current.④ Mr. Adams: I infer from your discription that it keeps repeating itself over long periods of time. Is that correct? Engineer: Yes. Each repetition is called a cycle, and the amount of time taken for a wave to undergo one cycle is its period. Mr. Adams: It would seem to me that the shorter the period of the wave, the more cycles per second it would have. Engineer: Correct. The number of cycles per second is the wave’s frequency measured in hertz (Hz). Mr. Adams: I assume we can start measuring the current at any given instant in time and still be able to determine the period.⑤ Engineer: Correct. In fact, any given instant in time for a cyclical waveform has an associated stage of wave development known as the phase of the wave.
