小学五年级英语口语学习知识点
单词音节重读
Today’s tip is on how syllable stress can affect the meaning of words.
今天的小贴士是关于音节重音如何影响单词的意思。
Remember that stressed syllables are said louder and are lengthened, and unstressed syllables are pronounced more softly, and often have the vowel sounds reduced.
要记住重音的音节会发得会大声，声音会延长，而非重读音节就会发得较轻，但经常是元音声音降低。
Sometimes, this difference can be the difference between a verb and a noun, or an adjective.
有时，这种不同可以区分动词与名词或形容词。
There are at least 14 pairs of words in which syllable stress alone makes this difference.
至少在十四组单词里面，重读音节就会区分单词。
Some examples include `addict, a`ddict, `convict, con`vict, `perfect, per`fect.
一些例子包括：`addict, a`ddict, `convict, con`vict, `perfect, per`fect.
Each time the second syllable is stressed, the word is a verb.
当单词里第二个音节重读的话，这个单词就是一个动词。
When the first syllable is stressed, the word is either a noun or an adjective.
当第一个音节重读的话，这个单词可以是一个名词也可以是一个形容词。
Let’s look some examples more closely.
让我们来更仔细地看一些例子。
`Permit and per`mit, `permit和per`mit A `permit is a noun, it is a piece of paper which authorizes you to do something.
单词`permit就是一个名词，意思是许可证;执照
For instance, a fishing `permit allows you to go fishing.
比如说，有了捕鱼许可证就可以去钓鱼。
Permit is a verb.
Permit就是一个动词。
It means to allow.
意思就是允许。
For instance, fishing isn’t per`mitted here without a `permit.
比如说，没有许可证是不允许在这里钓鱼。
Another example is `perfect and per`fect. `Perfect is an adjective.
另一个例子就是`perfect和per`fect，`perfect 是一个形容词。
It means 100% correct, no mistakes or errors.
意思就是正确，没有错误。
The verb is perfect, it means to make something perfect.
perfect 是个动词，意思是使…完美。
For example, “I want to per`fect my English” means “I want to make my English perfect”.
比如说， “我想改善我的英文”意思是“我想让我的英文变得完美”.
Make sure you stress the right syllable. It can be the difference between different parts of speech.
确信重读在合适的音节，在句子中的不同位置重音也会不同。

字母" t "的发音

(" t "的发音)今天的小贴士是关于字母 " t " 的发音。
Of course the letter " t " is usually pounced " t ".

But you may have noticed that in fluent speech, native speakers sometimes pronounced the " t " as " d ".
但是你可能注意到在流利的口语中，以英语为母语的人有时就会把 " t " 发成 " d "。

在英语中有十五个发音的辅音。
Also, all vowel and diphthong sounds in English are voiced.
同样地，所有英语元音和双元音都是发声的。
So let’s look at some examples of words in which the " t " may be pronounced " d ".

1. "matter".

Also, a " t " does not sound like " d " when it comes before a stressed vowel as in "return".
而且是，" t " 不会发成 " d " 当它出现在如 "return" 中一个重音的元音前面。
