Một số cấu trúc thường gặp
3. Lối nói phụ họa
3.1. Phụ họa câu khẳng định
– Khi muốn nói một người hoặc vật nào đó làm một việc gì đó và một người, vật khác cũng làm một việc như vậy, người ta dùng so hoặc too. Để tránh phải lặp lại các từ của câu trước (mệnh đề chính), người ta dùng liên từ and và thêm một câu đơn giản (mệnh đề phụ) có sử dụng so hoặc too. Ý nghĩa của hai từ này có nghĩa là “cũng thế”.
John went to the mountains on his vacation, and we did too.
John went to the mountains on his vacation, and so did we.
I will be in Vietnam in May, and they will too.
I will be in Vietnam in May, and so will they.
He has seen her play, and the girls have too.
He has seen her play, and so have the girls.
We are going to the movie tonight, and he is too.
We are going to the movie tonight, and so is he.
She will wear a custom to the party, and we will too.
She will wear a custom to the party, and so will we.
Picaso was a famous painter, and Rubens was too.
Picaso was a famous painter, and so was Rubens.
Tuỳ theo từ nào được dùng mà cấu trúc câu có sự thay đổi:
– Khi trong mệnh đề chính có động từ be ở bất cứ thời nào thì trong mệnh đề phụ cũng dùng từ be ở thời đó.
Affirmative statement (be) + and + S + verb + too
Affirmative statement (be) + and + so + verb + S
I am happy, and you are too.
I am happy, and so are you.
– Khi trong mệnh đề chính có một cụm trợ động từ + động từ], ví dụ will go, should do, has done, have written, must consider, ... thì các trợ động từ trong mệnh đề đó được dùng lại trong mệnh đề phụ.
They will work in the lab tomorrow, and you will too.
They will work in the lab tomorrow, and so will you.
– Khi trong mệnh đề chính không phải là động từ be, cũng không có trợ động từ, bạn phải dùng các từ do, does, did làm trợ động từ thay thế. Thời và thể của trợ động từ này phải chia theo chủ ngữ của mệnh đề phụ.
Affirmative statement + and + S + do/does/did + too
Affirmative statement + and + so + do/does/did + S
Jane goes to that school, and my sister does too.
Jane goes to that school, and so does my sister.
3.2. Phụ hoạ câu phủ định
– Cũng giống như too và so trong câu khẳng định, để phụ hoạ một câu phủ định, người ta dùng 'either' (cũng) hoặc 'neither' (cũng không). Ba quy tắc đối với trợ động từ, động từ be hoặc do, does, did cũng được áp dụng giống như trên. Ta cũng có thể gói gọn 3 quy tắc đó vào một công thức như sau:
Negative statement + and + S + negative auxiliary (or be) + either
Negative statement + and + neither + positive auxiliary (or be) + S
I didn't see Mary this morning, and John didn't either
I didn't see Mary this morning, and neither did John.
She won’t be going to the conference, and her friends won’t either.
