"is used" tại sao sau is lại là V2 mà không phải là V-ing.
"This fruit is used at both states, ripe and unripe."
Solar panels are placed on the roof of a house and the sun's energy is used to heat water.
Theo công thức thì heat phaỉ thêm ing. Sao lại giữ nguyên vậy ạ.
-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!

Should women find their happiness inside or outside the home? In the United States people used to believe the saying, "A woman's place is in the home." But now both women and society are changing. More than fifty percent of American women continue their work even after they are married. What has brought about these changes? What is happening to the American family today?Up until the 1950's a typical American woman got married in her early 20's. In those days she quit her job andbecame a mother. "A woman's place is in the home" was a popular saying. Most women felt that taking care of their home and family was their full-time job.But times have changed. Women are getting married later these days and more have chosen to stay single. Others get married but decide not to have any children. Today more than fifty percent of all married women work full-time. Many others run businesses in their homes.What has caused these major changes? One reason is economic necessity. It may be that the husband has lost his job and the wife must support the family. Or even if the husband is working, some families say they can't survive on only one paycheck.But probably a more important influence has been the "women's liberation movement." Women are being told in many magazines and TV programs: "You can be successful on your own. Don't be satisfied with just being a wife and mother. Use your intelligence and talents to do something bigger. And you should be paid as much as a man."No doubt this movement has accomplished much good. But it has also contributed to a selfish "me first" attitude that is breaking up many families. Sometimes women who are happy staying at home feel that working women look down on them.There are no easy answers to these problems. But certainly women's influence will continue to grow in business, education and politics.
