× My favorite machine is air conditioner.

✓ My favorite machine is an air conditioner.

在英语中，单数可数名词前通常需要冠词。这里的'air conditioner'是单数可数名词，前面应加不定冠词'an'。

× They are a useful machine to save the time and the effort compared to doing housework by hand and it's can enhance our life quality.

✓ They are useful machines to save time and effort compared to doing housework by hand, and they can enhance our quality of life.

主语'they'是复数，谓语和后续名词也应使用复数形式。'a useful machine'应改为'useful machines'。'the time and the effort'中'the'不必要，应去掉。'it's can'是错误的，应改为'they can'。'life quality'表达不自然，应改为'quality of life'。

× They are a useful machine to save the time and the effort compared to doing housework by hand and it's can enhance our life quality.

✓ They are useful machines to save time and effort compared to doing housework by hand, and they can enhance our quality of life.

在泛指时间和努力时，不需要使用定冠词'the'，应直接使用'time'和'effort'。

× and it's can enhance our life quality.

✓ and they can enhance our quality of life.

'it's'是'it is'的缩写，指代单数，而前文主语是复数'they'，应保持一致。

× Following the instruction when you use the machine will protect us from some potential dangers such as explosion and it also benefit for the machine itself.

✓ Following the instructions when you use the machine will protect us from some potential dangers such as explosions, and it also benefits the machine itself.

'instruction'应为复数形式'instructions'，表示说明书。'explosion'应为复数'explosions'，表示多种可能的危险。'benefit for'用法错误，应改为'venefits'加宾语。

× Following the instruction when you use the machine will protect us from some potential dangers such as explosion and it also benefit for the machine itself.

✓ Following the instructions when you use the machine will protect us from some potential dangers such as explosions, and it also benefits the machine itself.

动词'benefit'应使用第三人称单数形式'benefits'，因为主语是单数。

× It can ensure the machine be used properly and last longer. And.

✓ It can ensure the machine is used properly and lasts longer.

'ensure the machine be used'结构不正确，应改为'ensure the machine is used'。'last'应改为第三人称单数'lasts'以与主语'machine'一致。句尾的'And.'为不完整句，应删除。
