All bottles_______before transportation.
A. frozen
B. were froze
C. were frozen
D. are frozen
Đáp án C
Kiến thức: câu bị động
Giải thích:
Trong câu này, động từ cần phải ở dạng bị động quá khứ vì hành động "frozen" (đóng băng) được thực hiện đối với các chai trước khi chúng được vận chuyển.
Cấu trúc "were frozen" là hình thức bị động quá khứ chính xác, vì "were" là động từ ở thì quá khứ, còn "frozen" là phân từ của động từ "freeze."
A. frozen: Dạng tính từ này không thể đứng độc lập mà không có động từ "were" để tạo thành câu bị động.
B. were froze: "Froze" là dạng quá khứ của động từ "freeze," nhưng khi sử dụng câu bị động, cần phải dùng phân từ quá khứ "frozen."
D. are frozen: Câu này ở thì hiện tại bị động, nhưng ngữ cảnh yêu cầu thì quá khứ (trước khi vận chuyển).
Dịch: Tất cả chai lọ được đóng băng trước khi vận chuyển.

The government is introducing strict new rules on the dumping of ____ by industry.
After years of hype and false starts, the shift to clean power has begun to accelerate at a pace that has taken the most experienced experts by surprise. Even leaders in the oil and gas sector have been forced to confront an existential question: will the 21st century be the last one for fossil fuels?
It is early, but the evidence is mounting. Wind and solar parks are being built at unprecedented rates, threatening the business models of established power companies. Electric cars that were hard to even buy eight years ago are selling at an exponential rate, in the process driving down the price of batteries that hold the key to unleashing new levels of green growth.
“This clean energy disruption has just started and what is striking is how much of a financial impact it is already having on some companies,” says Per Lekander, a portfolio manager at London’s Lansdowne Partners hedge fund, who has tracked global energy markets for more than 25 years.
“It hit the electricity sector first, in Europe in 2013 and then the US two years later. Now it has spread to the auto sector and I think the oil industry is next.”
The shift has come as increased government efforts to curb climate change and smog have driven down costs and spurred technical advances, creating a green energy industry that looks nothing like it did a decade ago: expensive and sluggish.
Today, China and India have picked up the baton and are driving a sector that has spread to every continent. The result was a banner year for green energy in 2016.
It is stated in the passage that in the past, green energy ____
