Chú ý khi giải:

Dịch bài đọc:

     Năm 2010, nhóm bảo vệ hành tinh tại NASA đã xác định và khai thác 90% các tiểu hành tinh gần Trái đất có chiều rộng một km. Những 'vật thể gần Trái đất' này, hay NEO, có kích thước bằng những ngọn núi và bao gồm bất cứ thứ gì trong phạm vi 50 triệu km quanh quỹ đạo Trái đất. Với ước tính còn lại 50 tiểu hành tinh để khai thác (chưa khai thác 50 tiểu hành tinh), NASA cho biết không cái nào trong số 887 cái mà họ biết là mối nguy hiểm đáng kể cho hành tinh.

     Hiện NASA đang làm việc để khai thác một số tiểu hành tinh nhỏ hơn, có chiều rộng từ 140 mét trở lên. Trong số 25.000 tiểu hành tinh ước tính có kích thước này, cho đến nay khoảng 8.000 cái đã được khai thác, còn 17.000 cái chưa được kiểm tra. Xét rằng một tiểu hành tinh 19 mét đã phát nổ phía trên thành phố Chelyabinsk của Nga vào năm 2013 khiến 1.200 người bị thương, những tiểu hành tinh cỡ trung bình này sẽ là mối nguy hiểm nghiêm trọng nếu chúng đi vào quỹ đạo của Trái đất.

     Liệu NASA có thể tìm thấy các NEO cỡ trung bình còn lại hay không phụ thuộc vào việc thu được tiền để xây dựng NEOCam, một kính viễn vọng không gian 0,5 mét sử dụng ánh sáng hồng ngoại để định vị các tiểu hành tinh. Nếu nhận được tiền, nó có thể đạt được mục tiêu trong vòng mười năm. Ngay khi khai thác xong, đội bảo vệ hành tinh vẫn cần phải tìm ra cách bảo vệ hành tinh khỏi bị tấn công bởi các tiểu hành tinh thực sự đáng lo ngại - PHAS.

Câu 1:

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks from 36 to 40.

 In 2010, the planetary defence team at NASA had (36) _____ and logged 90 percent of the asteroids near Earth measuring one kilometre wide. These 'near-Earth objects', or NEOs, are the size of mountains and include anything within 50 million kilometres of Earth's orbit. With an estimated 50 left to log, NASA says none of the 887 (37) _____ it knows about are a significant danger to the planet.

 Now NASA is working towards logging (38) _____ of the smaller asteroids, those measuring 140 metres wide or more. Of the 25,000 estimated asteroids of this size, so far about 8,000 have been logged, leaving 17,000 unaccounted for. Considering that a 19-metre asteroid that exploded above the city of Chelyabinsk in Russia in 2013 injured 1,200 people, these middle-sized asteroids would be a serious danger if they enter Earth's orbit.

 Whether NASA can find the remaining middle-sized NEOs depends on getting the money to build NEOCam, a 0.5-metre space telescope which would use infrared light to (39) _____ asteroids. If it did get the money, it could probably achieve its goal in ten years. (40) _____ logged, the planetary defence team would still need to work out how to defend the planet against being hit by the truly worrying asteroids - the PHAS.

Câu 2:

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 following questions from 31 to 35.

 A Plastic Ocean is a film to make you think. Think, and then act. We need to take action on our dependence on plastic. We've been producing plastic in huge quantities since the 1940s. Drink bottles, shopping bags, toiletries and even clothes are made with plastic. We live in a world full of plastic, and only a small proportion is recycled. What happens to all the rest? This is the question the film A Plastic Ocean answers. It is a documentary that looks at the impact that plastic waste has on the environment. Spoiler alert: the impact is devastating.

 The film begins as a journey to film the largest animal on the planet, the blue whale. But during the journey the filmmakers (journalist Craig Leeson and environmental activist Tanya Streeter) make the shocking discovery of a huge, thick layer of plastic floating in the middle of the Indian Ocean. This prompts them to travel around the world to look at other areas that have been affected. In total, they visited 20 locations around the world during the four years it took them to make the film. The documentary premiered in 2016, and is now on streaming services such as Netflix.

 It's very clear that a lot of research went into the film. There are beautiful shots of the seas and marine life. These are contrasted with scenes of polluted cities and dumps full of plastic rubbish. We see how marine species are being killed by all the plastic we are dumping in the ocean. The message about our use of plastic is painfully obvious.

 But the film doesn't only present the negative side. In the second half, the filmmakers look at what we can do to reverse the tide of plastic flowing around the world. They present short-term and long-term solutions. These include avoiding plastic containers and ‘single-use’ plastic products as much as possible. Reuse your plastic bags and recycle as much as you can. The filmmakers also stress the need for governments to work more on recycling programmes, and look at how technology is developing that can convert plastic into fuel.

 We make a staggering amount of plastic. In terms of plastic bags alone, we use five hundred billion worldwide annually. Over 300 million tons of plastic are produced every year, and at least 8 million of those are dumped into the oceans. The results are disastrous, but it isn't too late to change. Once you've seen A Plastic Ocean, you'll realise the time is now and we all have a role to play.
