D1 1-3 CBD
1. C。第二段明显是统领全文的问题：勇士队还是骑士队会在这场备受期待的再次对决中获胜？之后对各队的可能获胜的原因和方面作分析。所以C正确，文章是对这个总决赛做前瞻。
2. B。根据第五段It’s （it指代Knocking down 3-pointers）a simple formula that Warriors coach Steve Kerr refuses to stop using.”可知B正确。A、C根据第三段可排除，根据第二段的Rematch及文章其他处都可排除D。
3. D。根据最后一段的They are trying to complete a dream season and have critics they still need to answer. They won the title last year, but they barely got to enjoy it because many people talked about them being lucky.可判断D正确。根据文章前两段可排除B。根据倒数第三段的最后两句可以排除C，作者没有对谁更可能胜出做出判断，尤其是最后一句问题，所以也排除AD项。
D2 1-4 DACA
1. D。此题考查整体篇章的理解。本文主要探讨了在西方国家，有关收入的话题也是非常敏感的，及如何巧妙的和别人谈论工资。正确答案为D。
2. A。此题考查第三段中举例的用意。US manners expert Thomas P. Farley explains why it is a taboo. Thomas P. Farley解释了收入是禁忌的原因：In American society, much of the respect we get from others is tied to what we earn （在美国社会，我们是否得到尊重很大程度和收入有关）。所以正确答案为A。
3. C。此题考查词义理解。由下文的“Get over it and try again another time”，以及相对比的发问方式用了than with a straight question，应能猜出词义为C。
4. A。此题考查最后一段的理解。文章谈到及时技巧地提问，也还是有些人不会做出具体回答的，毕竟money的话题是敏感又禁忌的问题。因此，正确答案为A。
D3 1-4 CAAC
1. C。根据第三段的Politicians use their voices to show their charm…以及第七段，可以猜出只有C项（charming，有魅力的）最符合语境。
2. A。根据第八段的They are meant to show power... A politician may speak at a lower pitch because he or she wants to seem powerful among equals可以得此答案。
3. A。根据倒数第三段可以得此答案。
4. C。根据最后一段的Next, the scientists want to see whether politicians in other countries share similar patterns可以得此答案。
D4 1-4 CCBD
1. C。作者在首段NOT long ago, I would have been surprised by how easy it is to lend a hand, brighten a day or make a difference. But now I’m not.可知。
2. C。由第三段My daughter was my primary inspiration. …But I wanted to do more, so I decided to do a good deed a day for 50 days.可知。
3. B。推理判断题。由文中第五段最后一句I could only hope I was inspiring ideas in others.和第六段最后一句somehow I knew I was making a difference. 可推知作者会继续做下去。A项不对，I felt almost guilty for the smallness of my simple deeds. 并非就是感到羞耻，只是说甚至因为做的小事而有些内疚。Like millions of others, I’m short on time and careful with spending.不符。D项和倒数第二段最后两句I picked up litter at the playground with other families watching. I could only hope I was inspiring ideas in others.不符。
4. D。主旨题，作者的经历说明“小善举会有大影响。”
D5 1-4 ABDC

3. D。四个选项中只有D项的持续时间是Duration 2 to 12 Weeks最长，所以答案为D。
4. C。查找小标题后对应的信息，不难选出正确答案C。
