Bài tập Tiếng Anh Lớp 8 Global Success theo unit - Unit 3: Teenagers

 Câu đơn là cấu trúc câu đơn giản nhất trong tiếng Anh, bao gồm chỉ một chủ ngữ 
(subject) và chỉ một vị ngữ (predicate). ( Câu chỉ có duy nhất một mệnh đề (Clause)) 
Example: 
 - My brother ate a sandwich. 
 - Tom uses Facebook to connect with friends.
 - He often chats with his friends on Facebook Messenger.
 - Students can discuss their problems in their class forum. 
Eg: Minh has some problems with his schoolwork.
 S V
+ Câu đơn có thể có nhiều hơn một chủ từ hoặc nhiều hơn một động từ, nhưng chỉ diễn đạt 
một ý chính duy nhất. 
Example: 
 - John and Mary were sad. 
 - My friends and I joined a sports competition last year.
 - Smith ate noodles and drank coffee. 
+ Khi viết tiếng Anh, chúng ta nên hạn chế dùng một chuỗi các câu đơn liên tiếp vì điều này 
sẽ làm người đọc khó chịu, trừ khi người viết có chủ ý. 
- I went to the supermarker yesterday. 
- Mary and Tom are playing tenis.
- John always goes jogging early in the morning. 
- John and Mary always go jogging early in the morning. 
2. Câu ghép – Compound Sentences 
 Câu ghép, hay còn gọi là câu tập hợp, là câu gồm hai hay nhiều mệnh đề độc lập có liên 
quan về mặt ý nghĩa, được kết nối với nhau bằng một liên từ (conjunction) hoặc bằng một 
dấu chấm phẩy (semicolon).
 Câu ghép là câu được hình thành bởi hai hay nhiều mệnh đề độc lập. Các mệnh đề này 
được nối với nhau bằng liên từ (FOR, AND, NOR, BUT, OR, YET). (FANBOY).
