          A report from the United Nations given at the conference unveils how worrying the pollution caused by plastic utensils, especially plastic bags, is becoming. In a single minute, the world consumes one million plastic bottles; in a year, the world consumes five billion single-use plastic bags, according to Vietnamplus. The scary fact is that such plastic bottles and bags are not properly treated, as each year, the world discharges 300 million tons of plastic waste, accounting for some 10% of all solid waste, putting the environment and human health under tenterhooks, according to the news site.

The conference also drew attention to another fact: “For a plastic bag that can be used for five minutes, it takes five seconds to produce, one second to discard, but 500 to 1,000 years to become totally decomposed,” says Vietnamplus.

In another message given by the UN General Secretary and delivered at the conference, it is reported that since more than eight million tons of plastic bags end up in the oceans each year, “microplastics in the seas now outnumber stars in our galaxy.” “If present trends continue, by 2050 our oceans will have more plastic than fish,” Dan Tri reports, quoting Caitlin Wiesen, country director of the UN Development Programme in Vietnam.

These above-mentioned fearful facts, however, are not merely global issues, but domestic problems as well, according to local media. Many local news outlets, when relating data from the conference, point out that white pollution – a term used to indicate the overwhelming discharge of plastic bags into the environment – is even getting worse in Vietnam than elsewhere

What does the phrase “present trends” in paragraph 3 refer to?

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.

        The "greenhouse effect" is the warming that happens when certain gases in Earth's atmosphere (26) ________ heat. These gases let in light but keep heat from escaping, like the glass walls of a greenhouse. First, sunlight shines onto the Earth's surface, (27) ______ it is absorbed and then radiates back into the atmosphere as heat. In the atmosphere, “greenhouse gases trap some of this heat, and the the rest escapes into space. The more greenhouse gases are in the atmosphere, the more heat gets trapped.

        Scientists have known about the greenhouse effect since 1824, when Joseph Fourier calculated that the Earth would be much colder if it had no atmosphere. This greenhouse effect is what keeps the Earth's climate (28) _________. Without it, the Earth's surface would be an average of about 60 degrees Fahrenheit cooler. Scientists often use the term "climate change" instead of global warming. This is because as the Earth's average temperature climbs, winds and ocean currents move heat around the globe in ways that can cool some areas, warm (29) ___________, and change the amount of rain and snow falling. (30)_________, the climate changes differently in different areas
