Question

Many scientists believe our love of sugar may actually be an addiction. When we eat or drink sugary foods, the sugar enters our blood and affects parts of our brain that make us feel good. Then the good feeling goes away, leaving us wanting more. All tasty foods do this, but sugar has a particularly strong effect. In this way, it is in fact an addictive drug, one that doctors recommend we all cut down on.

"It seems like every time I study an illness and trace a path to the first cause, I find my way back to sugar," says scientist Richard Johnson. One- third of adults worldwide have high blood pressure, and up to 347 million have diabetes. Why? "Sugar, we believe, is one of the culprits, if not the major culprit," says Johnson.

Our bodies are designed to survive on very little sugar. Early humans often had very little food, so our bodies learned to be very efficient in storing sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. So the very thing that once saved us may now be killing us.

So what is the solution? It's obvious that we need to eat less sugar. The trouble is, in today's world, it's extremely difficult to avoid. From breakfast cereals to after-dinner desserts, our foods are increasingly filled with it. Some manufacturers even use sugar to replace taste in foods that are advertised as low in fat.

 

But there are those who are fighting back against sugar. Many schools are replacing sugary desserts with healthier options like fruit. Other schools are growing their own food in gardens, or building facilities like walking tracks so students and others in the community can exercise. The battle has not yet been lost. 

What does the phrase "the very thing" in paragraph 3 refer to? 

A. the amount of sugar in our food 

B. having enough food to survive 

C. our ability to store sugar as fat 

D. early humans' lack of food

Đáp án C

Kiến thức: Đọc hiểu

Giải thích:

Cụm từ "the very thing" trong đoạn 3 nói về điều gì?

A. lượng đường trong thức ăn của chúng ta

B. có đủ thức ăn để tồn tại

C. khả năng lưu trữ đường của chúng ta dưới dạng chất béo         

D. sự thiếu thức ăn của con người ngày xưa

"the very thing" đề cập đến khả năng lưu trữ đường của chúng ta dưới dạng chất béo ở câu trước: Early humans often had very little food, so our bodies learned to be very efficient in storing sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. So the very thing that once saved us may now be killing us.

Tạm dịch: Con người thời kỳ ngày xưa thường có rất ít thức ăn, vì vậy cơ thể chúng ta học được cách rất hiệu quả trong việc lưu trữ đường dưới dạng chất béo. Theo cách này, chúng ta đã dự trữ năng lượng khi không có thức ăn. Nhưng ngày nay, hầu hết mọi người có quá nhiều. Vì vậy, thứ từng cứu chúng ta bây giờ có thể đang giết chúng ta.
