18、ffer a continuous solution for parts of the world which are likely to suffer from flooding because of climate change, a new study has found.Bangladeshs floating gardens began hundreds of years ago.

19、sing and filling with the waters. Historically, they were used to continue growing food during rainy seasons when rivers were filled with water.The farmers layer the plants about three feet deep, creating a version of raised-bed gardens that float in the water. Then, they plant vegetables inside tho
20、se rafts. As the raft-plants rot away, they release nutrients, which help feed the vegetable plants. But as climate change affected the volume of water in those rivers, the researchers wanted to understand whether Bangladeshs floating gardens could be a continuous farming practice. They interviewed
21、farming families and found strong evidence that floating gardens provide stability, both in the amount of food available to feed rural populations and in a farming familys income.They found that farmers typically use hybrid (杂交) seeds, which must be repurchased each year, to grow a diverse range of
22、vegetables in the floating gardens. The gardens are also sensitive to pests, so farmers end up spending some money on both pesticides and fertilizers. But even with those expenses, they found, benefits outweighed costs. One farmer told the research team that he earns up to four times as much money f

28、escope and the most sensitive single-dish radio telescope. The receiving surface area of FAST is 250,000 square meters, about the size of 30 standard football fields. Its construction was completed in September 2016 and it officially began operating in January 2020.The major scientific task of the t
29、elescope is the observation of pulsars (脉冲星) the rotating neutron stars. The study of pulsars can help to confirm the existence of gravitational radiation and black holes, and help solve many other major questions in physics. Another scientific goal of FAST is to search for outer space civilization.
30、The telescope is located in a naturally deep and round karst depression in southwest Chinas Guizhou Province. The first advantage of the selected site is the altitude. The average altitude of Guizhou is about 1,100 meters, which maximizes the effectiveness of the observation equipment. Secondly, the
