— How can I improve my English more quickly?
—_____ listening and reading more.
本题考查介词by的用法
问句问的是“我怎样才能更快速地提高我的英语水平”，答语的含义是“通过多听多读的方式”，故所缺的介词是by。
It's a good idea to _____ new words in the dictionary if you don't know their meanings.
三个选项的含义分别是：put up搭建，张贴；look up查阅，向上看；end up最后处于。根据本题语境可知，如果你不知道一些生词的意思，在词典里“查阅”一下它们的含义是个好主意，故答案为选项B。
按要求完成句子，每空一词。
