Đáp án đúng: C
Kiến thức về câu bị động đặc biệt
Căn cứ vào cấu trúc câu bị động đặc biệt với các động từ chỉ quan điểm, ý kiến: - S1 + V1 + that + S2 + V2 +….
→ S2 + be + V1 (pp) + to V2 (bare)/to have V2 (pp) + …. + Dùng “to V (bare)” khi hai động từ V1 và V2 cùng thì + Dùng “to have Vpp” khi hai động từ V1 và V2 khác thì
Xét trong câu, vì hành động thứ hai “cause” là hành động đã xảy ra và hoàn toàn kết thúc trong quá khứ trong khi động từ đầu “is believed” được chia ở thể bị động của hiện tại đơn, theo quy tắc ta dùng “to have Vpp”.
Xét về nghĩa, động từ thứ hai tiếp tục là một động từ cần chia ở thể bị động vì nó mang nghĩa là “bị gây ra bởi”.
Tạm dịch: Sự tuyệt chủng của các loài khủng long được tin rằng đã bị gây ra bởi một ngôi sao băng khổng lồ đã đâm sầm vào Trái Đất của chúng ta.
Cấu trúc cần lưu ý:
Crash into sth (phr.v): đâm sầm vào, va chạm vào đâu/cái gì
