Answer 1

分析 短文大意：本文主要講了潮汐對英國的影響，高的潮汐和低的潮汐的不同．

解答 48．Britain's tides；文章主旨大意理解題，根據對全文的理解，注意講述英國的潮汐，故填Britain's tides．
49．
①The tides are very high to go into the towns．
②In winter，the very strong winds and the high tides"eat"parts of Britain．理解歸納題，講到高的潮汐和低的潮汐對英國的影響，有兩處講到其不利之處，第一處，原文句子Sometimes the tides are very high and this can be a big problem for towns near the coast．有時潮汐很高，這能成為小鎮(zhèn)的海岸的一個大問題，所以不利之處其一：①The tides are very high to go into the towns；第二處，在冬天非常強的風和高的潮汐吃掉英國的一部分，故填：②In winter，the very strong winds and the high tides"eat"parts of Britain．
50．Yes，I do．  Because the tides can help to make electricity and cleans the beaches．文章理解題，根據文章內容也講述了潮汐的益處，如原文句子As the tides comes in and goes out，it cleans the beaches．In the port，the ships wait for the high tide．隨著潮汐的進與退，它打掃了沙灘．在港口，輪船等候高的潮汐．故原因為：Because the tides can help to make electricity and cleans the beaches
