CHUYÊN ĐỀ ĐỘNG TỪ NGUYÊN MẪU CÓ “TO” VÀ KHÔNG “TO” TRONG TIẾNG ANH
1. Lý thuyết
1.1. Động từ nguyên mẫu có to (Infinitive with to)
Động từ nguyên mẫu có to được dùng làm:
- Chủ ngữ (subjects):
Ví dụ:
To swim is good for our health.
* Lưu ý: Trong Tiếng Anh hiện đại, cấu trúc với chủ ngữ giả “it” thường được dùng hơn.
It is good for our health to swim.
- Tân ngữ: (Object)
+ Tân ngữ trực tiếp cho các từ
afford, agree, arrange, appear, ask, attempt, care, choose, claim, decide, demand, deserve, expect, fail, happen, hesitate, hope, intend, learn, manage, neglect, offer, plan, prepare, pretend, promise, propose, refuse, seem, swear, tend, threaten, vow, wait, want, wish, would like, yearn, urge

+ To-infinitive cũng được dùng sau các cụm từ:
to make up one’s mind: quyết định
to take care: chăm sóc
to make sure: chắc chắn

It’s nice to meet you here.
+ Dùng sau các nghi vấn từ trong lời nói gián tiếp (ngoại trừ why).
Ví dụ:

- Bổ ngữ:
+ Bổ ngữ cho chủ ngữ (subjective complements)
Ví dụ:
What you have to do is to work harder.
+ Bổ ngữ cho tân ngữ (Objective complements)

1.2. Động từ nguyên mẫu không to (Infinitive without to)
Động từ nguyên mẫu không to được dùng:
- Sau các trợ động từ khuyết thiếu (modal verbs).
Ví dụ:
We must go now.
- Sau các động từ: let, make, help, see, hear, feel, watch, notice + tân ngữ.
Ví dụ:

Lưu ý: Sau help + object có thể là một động từ nguyên mẫu có to hoặc không to.
