Ask for the usage of as well as and as well
There is only one word difference between as well and as well as, but the meaning and usage are very different.
1. As well Usage:
1. As well is often used as an adverbial, and is interpreted as "also; also", which is equivalent to too or also, and is often located at the end of the sentence, without the need for a comma separate from the sentence. For example:
I am going to London and my sister is going as well (=going, too).
I am going to London and my sister is going as well.
I not only play the guitar, I sing as well (＝I also sing).
I not only play the guitar, but I also sing.
2. As well can also be used in sentences in spoken language, meaning "it's okay, that's OK" or "it's better" to soften the tone. Such as:
You may as well go,
You may as well go.
The weather was so bad that we might (just) as well have stayed at home.
If I had known this, I might as well have stayed at home.
3. As well can be used directly after just as a response (can be regarded as the omission of "It's just as well"), meaning "fortunately, fortunately; it doesn't matter; it doesn't matter". Such as:
—We were too late to see the film.
We were too late to see the film.
—Just as well, I hear it isn't very good.
No need to be sorry, I hear the movie isn't very good either.
2. Usage of as well as
1. As well as is often used to connect two parallel components and is interpreted as "ye, huan". It emphasizes the former and mentions the latter only in passing. Therefore, when connecting parallel subjects, the predicate verb agrees with the previous item; and when connecting with not only...but also..., the predicate verb agrees with the latter item. Such as:
Your wife as well as you is friendly to me.
Not only you but your wife are also friendly to me.
（＝Not only you but also your wife is friendly to me,）
Electric energy can be changed into light energy as well as into sound energy.
Electrical energy can be converted into both sound energy and light energy.
2. As well as is used to express peer comparison, meaning "as good". For example:
You look as well as you did ten years ago.
Your body still looks as good as it did ten years ago.
He plays the guitar as well as you.
He plays the guitar as well as you.
