A study 【小题1】(lead) by Stanford University explores the influence microplastics(塑料微粒) have on whales. Microplastics are pieces of plastic less than five millimeters in length and are now frequently found 【小题2】 the whales live. The team found the whales mainly find food from 50 to 250 meters below the surface. At such depth, the highest concentrations of microplastic in the open ocean take place. Researchers estimate that up to 10 million pieces 【小题3】(consume) by each whale per day.

The Fukushima Daiichi nuclear power plant in Japan was 【小题1】 (severe) damaged by a tsunami in 2011, leading to a major nuclear disaster. Since then, water has been continuously used 【小题2】(cool) the damaged reactors (反应堆) and prevent further damage.

Tokyo Electric Power Company (TEPCO), the 【小题3】(operate) of the plant, said that the storage tanks took up too much space due to the wastewater. So Japan initially said that it 【小题4】(begin) releasing the water into the ocean in the spring of 2023.

On March 17, part of the equipment 【小题5】was related to the discharge of nuclear-contaminated water from the Fukushima Daiichi nuclear power plant started operation for 【小题6】first time, according to Japanese media TV Asahi.

According to The Guardian, the Japanese government argued that the water 【小题7】(treat) to remove most of the radioactive isotopes (同位素), so the water would be safe to be released into the ocean.

However, not everyone agrees with this decision. Environmental groups and local fishermen have expressed concern about the impact of the wastewater 【小题8】marine life and the fishing industry, the BBC reported.

The Chinese Foreign Ministry on March14 once again denounced (谴责) Japan’s unilateral (单边的) decision to dump nuclear-contaminated wastewater into the sea, 【小题9】(consider) the move an attempt to shift the risk of nuclear pollution to all of mankind.

The ministry also warned the country not to start the plan 【小题10】full consultation (磋商) with its neighbors and relevant international institutions.

Air pollution, global warming and overflowing landfills are the most serious environmental problems we are currently facing today.

The main cause of air pollution is the burning of fossil fuels.Other human activities,such as construction and the burning of waste,also contribute to air pollution.The effects on our health can be very serious.You can easily contribute to 【小题1】 (reduce) air pollution by using public transport.

Global warming 【小题2】 (cause) by the build-up of carbon dioxide and other pollutants in the atmosphere.These trap the sun’s heat and warm up the planet.Global warming has already caused 【小题3】 wide range of problems.

Landfills are used for waste disposal in many countries around the world.However,due 【小题4】 the amount of waste our lifestyles produce,these landfills are now reaching full capacity.When this happens,the chances of dangerous 【小题5】 (chemical) in the waste entering our water supply increase.The amount of waste in landfills in China 【小题6】 (rise) greatly over the last decade.The government is now trying to find alternative waste disposal methods.Apart from the three Rs (Reduce,Reuse and Recycle),some experts have begun advocating the fourth R — Responsibility.They believe 【小题7】although recycling waste is effective,the most effective way of solving the problem of overflowing landfills 【小题8】 (be) to encourage people 【小题9】 (take) responsibility for reducing the waste they produce 【小题10】 (they).
