=>I suggest that valuable things should be protected in pagodas and temples.
- $S$1 + suggest + (that) +  $S$2 + should + (not) + V (Bare).

- "suggest + V-ing/ mệnh đề chứa should" được dùng khi muốn đưa ra ý kiến, gợi ý hay đề xuất của chúng ta về việc ai đó nên làm gì.

- Vì "valuable things" không phải chủ thể gây ra hành động.

→ Câu bị động với động từ khuyết thiếu (Should): S + should + be + V (Pii) + (by O).
