Chào cả lớp. Hôm nay tôi muốn nói với các bạn về hai nguồn năng lượng. Chúng là những nguồn không thể tái tạo và những nguồn có thể tái tạo.
Các nguồn không thể tái tạo là than đá, dầu mỏ và khí đốt tự nhiên. Chúng ta có thể sử dụng những nguồn này để sản xuất năng lượng. Chúng rẻ và dễ sử dụng. Mọi người sử dụng chúng rất nhiều. Nhưng chúng rất hạn chế và sẽ hết sớm.
Các nguồn tái tạo đến từ mặt trời, gió hoặc nước. Khi năng lượng đến từ mặt trời, chúng ta gọi nó là năng lượng mặt trời. Năng lượng gió đến từ gió, và năng lượng thủy điện đến từ nước. Nguồn tái tạo có sẵn, sạch sẽ và an toàn để sử dụng. Nhưng chúng đắt tiền để sản xuất.
Trong tương lai, chúng ta sẽ dựa nhiều hơn vào các nguồn năng lượng tái tạo. Chúng tốt hơn cho môi trường và chúng sẽ không cạn kiệt.
1. Nguồn không tái tạo được rẻ và _________.
A. có sẵn
B. dễ sử dụng
C. đắt
2. ________nhận được từ mặt trời, gió hoặc nước.
A. Nguồn tái tạo
B. Tất cả các nguồn năng lượng
C. Các nguồn không thể tái tạo
3. Khi năng lượng đến từ nước, chúng ta gọi nó là_________.
A. năng lượng gió
B. năng lượng mặt trời
C. năng lượng thủy
4. Các nguồn năng lượng tái tạo tốt hơn cho ____.
A. môi trường
B. xe của chúng tôi
C. năng lượng thủy
1. B
Non – renewable sources are cheap and easy to use.
(Năng lượng không thể tái tạo thì rẻ và dễ sử dụng.)
Thông tin: Non-renewable sources are coal, oil and natural gas. ... They are cheap and easy to use.
(Các nguồn không thể tái tạo là than đá, dầu mỏ và khí đốt tự nhiên. ... Chúng rẻ và dễ sử dụng.)
2. ARenewable sources come from the sun, wind or water.
(Các nguồn năng lượng có thể tái tạo đến từ mặt trời, gió và nước.)
Thông tin: Renewable sources come from the sun, wind or water.
(Các nguồn tái tạo đến từ mặt trời, gió hoặc nước.)
3. C
When energy comes from water, we call it hydro energy.
(Khi năng lượng đến từ nước, chúng ta gọi nó là năng lượng thủy điện.)
Thông tin: Wind energy comes from the wind, and hydro energy comes from water.
(Năng lượng gió đến từ gió, và năng lượng thủy điện đến từ nước.)
4. A
Renewable energy sources are better for the environment.
(Các nguồn năng lượng có thể tái tạo thì tốt hơn cho môi trường.)
Thông tin: In the future we will rely more on renewable energy sources. They are better for the environment and they will not run out.
(Trong tương lai, chúng tôi sẽ dựa nhiều hơn vào các nguồn năng lượng tái tạo. Chúng tốt hơn cho môi trường và chúng sẽ không cạn kiệt.)
