Are you looking for a cheap. clean, effective source of power that doesn't cause pollution or waste natural resources? Look no further than solar energy from the sun. At present, most of our electricity comes from the use of coal, gas, oil, or nuclear power. This power could be provided by the sun. One percent of the solar energy that reaches the Earth is enough to provide power for the total pollution. Many countries are already using solar energy. Solar panels are placed on the roof of a house and the Sun's energy is used o heat water. The energy can be stored for a number of days, so on cloudy days you can use solar energy. Sweden has an advanced solar energy program. There, all buildings will be heated by solar energy and cars will use solar energy instead of gas by the year 2015.

-Vì câu này là câu bị động dạng hiện tại đơn (is used)[Công thức: S+am/is/are+PII]
-"to heat" ở đây là để chỉ mục đích (to+V-infinitive)
-Tạm dịch nghĩa của câu: Pin năng lượng mặt trời được đặt trên mái nhà và năng lượng của mặt trời được dùng để đun nóng nước
-Phân biệt "be" used to và "be" used[bị động]
+Về cấu trúc: ❉"be" used to + V-ing
❉Câu bị động[cấu trúc chung]: S+"be"+PII+(by O)+....
+Về nghĩa: ❉"be" used to V-ing: Quen với việc gì = get used to Ving = "be" accostumed to V-ing
❉"be" used: được dùng
-Do vậy, từ cấu trúc trên, ta thấy:
+Nếu câu trên là thuộc cấu trúc "be" used to Ving thì không hợp nghĩa của câu, làm gì có chuyện năng lượng của mặt trời lại quen với việc làm nóng nước
⇒Không phải cấu trúc "be" used to Ving
+Nếu ở đây dùng bị động thì sẽ hợp lý hơn, "be" used mang nghĩa là được dùng, to V ngay sau được dùng để chỉ mục đích[để làm nóng nước(to heat water)], trong câu trên thì is used và to heat là 2 từ riêng biệt, không nối nhau theo 1 cấu trúc mà theo 2 cấu trúc khác nhau [bị động và chỉ mục đích]
Để chính xác ngữ pháp thì câu nên được viết là "Solar panels are placed on the roof of a house and the sun's energy is used to heatING water." Đó là vì "heat" trong câu này được sử dụng như một động từ, và khi động từ này được sử dụng trong thì hiện tại tiếp diễn (present continuous tense), nó phải được bổ sung với "ing" ở cuối để hình thành thành phần "heating".
Vì vậy, câu trên nên được sửa lại thành "Solar panels are placed on the roof of a house and the sun's energy is used to heatING water." để đảm bảo ngữ pháp chính xác. Cảm ơn bạn đã chỉ ra điều này!
