Question 12.

Kiến thức được hỏi - Đảo ngữ của câu điều kiện loại I

Phương án A sai vì nếu ghép phương án A vào chỗ trống thì xuất hiện hai câu (đã có đầy đủ S + V), mà hai câu không thể được nối với nhau bằng dấu phẩy → sai về quy định ngữ pháp Tiếng Anh.

Phương án B dùng từ nối when nhưng vẫn sai vì nếu ghép phương án B vào chỗ trống thì tự nhiên xuất hiện be needed (be không được chia theo thì) sau chủ ngữ hydroelectric power → sai ngữ pháp

Phương án C cũng sai vì nêu ghép C vào chỗ trống thì be không được chia theo thì và nếu nối 2 mệnh đề thì phải cần từ nối → sai ngữ pháp

Đáp án đúng là D, đảo ngữ của câu điều kiện loại I ta đưa Should lên đầu

Tạm dịch: Nếu thủy điện là cần thiết thì lưu vực sông cần phải xả nước ra.

* Mở rộng:

Đảo ngữ với câu điều kiện loại I, II, III như sau:

Loại I: Should + S + V +       

Loại II: Were + S + to V +    

Loại III: Had + S + P2

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

Bitcoins are a form of virtual currency. In other words, they are a type of money that does not exist in the actual world. However, they can be used to purchase actual products and services from real companies.

The bitcoin system was created in 2009 by an enigmatic person named Satoshi Nakamoto. In fact, no one is sure if Satoshi Nakamoto is an actual person or a group of people. Bitcoins are designed to serve as an alternative to national currencies, such as dollars and euros. They can be used to pay for things instead of cash or credit cards, when bitcoins are transferred from a buyer to a seller, the transaction is recorded in a public database.

Governments are concerned that bitcoins can easily be stolen by hackers. It has dawned on them that they might be used for illegal purposes. For example, stolen goods could be purchased without the government’s knowledge. Although more and more companies are beginning to accept bitcoins, the percentage of purchases made using bitcoins is minuscule compared to other online payment methods, such as credit cards. Instead, many bitcoin owners simply keep them as an investment since more valuable in the future. This may or may not be a wise approach. Currently, the value of bitcoins is fluctuating wildly, especially when compared to highly stable national currencies, Bitcoin Investors are gambling on the hope that as this high-tech money becomes more widely accepted, its value will soar.
