I like this piece of music because it always makes me _____.
upset “心烦的” 、nevous“紧张的”、relaxed “放松的”，down “沮丧的，心情低落的”，根据题干中的 “我喜欢这首乐曲” 可推断，它总是使我觉得很 “放松”，故所缺的词是relaxed。
根据汉语及句末括号内的英语单词提示，用相关动词短语的适当形式完成句子（提示：不超过四个单词）
志愿者们正在努力地为俄罗斯世界杯提供更好的服务。(make)
The volunteersto provide Russia World Cup with better service.
考查固定搭配
本题考查 make an effort 的固定搭配。该短语意为 “作出努力”；再根据主语 the volunteers 和现在进行时的时态可知答案为 are making an effort。
—Hello! Could I speak to Mr. White?
—Sorry,he is out. I will ask him to call you as soon as he _____ back.
考查时间状语从句
本题考查 as soon as 引导的时间状语从句的时态。主句是一般将来时，从句要用一般现在时，故答案为选项B。
用括号中所给词的适当形式填空
—I want to show Paul around Nanjing on Saturday. Do you have any good ideas?
—Qixia Mount is well worth(visit) because of the red maple leaves.
本题考查 be worth doing 的结构，意为 “值得做……”。
—I don't know when _____ tomorrow.
—I will call you as soon as he _____.
宾语从句和状语从句
句意为：—我不知道他明天什么时候会来。—他一到我就给你打电话。know后面为一个when引导的宾语从句，宾语从句要用陈述句语序并且时间是明天，所以动词come的时态是一般将来时will come；在含有as soon as引导的时间状语从句的复合句中，主句用一般将来时，从句用一般现在时表将来，故选B选项。
—Leo is sure to come to our party. _____,he has already accepted the invitation.
—Hope he can show up on time.
短语的辨析
四个选项的含义分别是：in the end 最后，终于；as a result 因此；after all 毕竟，终究；in total 总共，共计。结合上下文可知，Leo 一定会来参加我们的聚会，毕竟，他已经接受了邀请，故答案为选项C。
