5.A debate
Is electricity a good thing or a bad thing?
A conclusion
Electricity can be both useful and dangerous.It all depends on how we use it.
English words are made up of different parts.
There parts are called syllables.Every word has one or more syllables.
Here are some common adjectives.
clean uncomfortable useful comfortable dangerous
Now,let's put these adjectives into comparative forms.
more uncomfortable
cleaner
more useful
more comfortable
more dangerous
Work out the rules
To make the comparative of adjectives
Add "-er" after words with one syllable.
Add "more" before words with two or more syllables.
There are exceptions:
Add "-er" after multisyllable words ending
with "-ow","able" and "-er".
For multisyllable words ending in "-y",change the "-y" to "-ier".
How many syllable do the following words have?
form cooker computer supermarket electricity
音節(jié)
| 音節(jié)是語(yǔ)音最小的單位，指一個(gè)字的讀音，通常一個(gè)單詞有幾個(gè)元音發(fā)音，就有幾個(gè)音節(jié)。 |
| 由元音音素單獨(dú)構(gòu)成 original中的o |
| 由元音音素加輔音字母構(gòu)成 habit中的ha和bit |
| 輔音音素中的響音/m/ /n/ /l/ /?/也能和他前面的輔音構(gòu)成一個(gè)音節(jié) able['e?bl]中的[bl] |
開(kāi)音節(jié)和閉音節(jié)
| 種類 | 構(gòu)成 | e.g. |
| 開(kāi)音節(jié) | 輔音+元音+輔音+e | name，bike，home，due，plane，shine |
