The tides can also help to make electricity．There are plans ti make electricity in the sea near Bristol．

Answer 1

分析 短文大意：本文主要讲了潮汐对英国的影响，高的潮汐和低的潮汐的不同．

解答 48．Britain's tides；文章主旨大意理解题，根据对全文的理解，注意讲述英国的潮汐，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．理解归纳题，讲到高的潮汐和低的潮汐对英国的影响，有两处讲到其不利之处，第一处，原文句子Sometimes the tides are very high and this can be a big problem for towns near the coast．有时潮汐很高，这能成为小镇的海岸的一个大问题，所以不利之处其一：①The tides are very high to go into the towns；第二处，在冬天非常强的风和高的潮汐吃掉英国的一部分，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．文章理解题，根据文章内容也讲述了潮汐的益处，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．随着潮汐的进与退，它打扫了沙滩．在港口，轮船等候高的潮汐．故原因为：Because the tides can help to make electricity and cleans the beaches
