Unit 3Under the sea.阅读理解2020海南五校模拟Engineers have put a huge garbage collector to gather plastic material in the Pacific Ocean between California and Hawaii, the worlds largest spread of garbage, twice the size of the state of Texas.The Ocean Cleanup organization created the collector. The groups founder, Boyan Slat, an inventor born in 1994, was just 16 when he was moved to clean up the oceans when he was on a dive and saw more plastic bags than fish.Last Saturday, a ship pulling the pipeshaped floating barrier left San Francisco. Attached to it is a screening skirt that hangs three meters down in the water. The screen is designed to collect the plastic as it moves through the water. Sea animals can safely swim under the barrier.The cleanup system also comes with lights powered by the sun, cameras, and other special devices (设备), so the system can communicate its position at all times. That way a support ship can find it every few months to remove the plastic that has been collected.Shipping containers will hold all the plastic gathered, including bottles and fishing equipment and are expected to be back on land within a year. Then the plastic will be recycled. The freefloating barriers are made to survive extreme weather conditions and damage from continual use. They will stay in the water for twenty years, thus collecting 90% of the garbage in the area.The Ocean Cleanup has received $35 million in donations to pay for the project, hoping to put 60 freefloating barriers in the Pacific Ocean by 2020. “Its important to turn off the taps on plastic entering the ocean, but I also think people can do more than one thing at a time to deal with this problem，” Slat said.1What drove Slat to invent the collector?AThe interest in invention.BHis failure to dive due to rubbish.CThe sight of too many plastic bags.DHis knowledge of garbage in the Pacific Ocean.2How does the floating barrier work?AIt reaches into the water to collect the plastic.BIt has large containers to produce power.CIt forms barriers to protect sea animals.DA ship drags it along in the ocean.3Which does the underlined word “it” in paragraph 4 refer to?AThe support ship.BThe floating barrier.CThe plastic to be recycled.DThe position of special devices.4What is important for protecting the ocean according to Slat?ASending more collectors into the ocean.BInventing more ocean cleanup devices.CStopping plastic from entering the ocean.DBanning the use of plastic bags in boats.七选五2020四川省绵阳市高三第二次诊断Many people look forward to the holiday season, which provides an opportunity to take a few days off, or go on a getaway. _1_ The combined effort of shopping, attending social events, and entertaining guests can quickly become too much to handle._2_ This means you may end up with financial pressure.
