体裁：应用文 题材：广告 主题：成年人教育课程
【语篇解读】 本文是一篇应用文，介绍了四门针对成年人教育的课程，即计算机课程、木工手艺、网页设计和艺术。
【难句分析】 Each lesson explores a different area of woodworking that will provide you with the skills needed for any woodworking project.
分析：本句是一个主从复合句。“that will provide you... woodworking project”为that引导的定语从句，修饰先行词“a different area of woodworking”， that在从句中作主语，“needed for any woodworking project”作skills的后置定语。
译文：每节课都会探讨木工手艺的一个不同的领域，它将会给你提供任何木工手艺项目所需要的技巧。
1．Which courses are suitable for beginners? A．Web Design and Art.
B．Computer Studies and Art. C．Woodwork and Web Design.

答案与解析：D 考查细节理解。根据Computer Studies部分中的“an understanding of computer fundamentals”可知，该课程提供计算机的基础内容；从Woodwork部分中的“the basics of woodworking”可知，该课程提供木工手艺的基础内容，故选D
项。
2．Which course awards students an official certificate?
A．Art. B．Woodwork.
C．Web Design. D．Computer Studies. 答案与解析：C 考查细节理解。根据Web Design部分中的“Students completing the course will receive the Diploma in Advanced Web Design”可知，该课程会给完成课程的学生颁发结业证书，另外三门课程均未提到颁发证书，故C项符合题意。 3．How much will a student who attends only half of all the Woodwork lessons pay in total?
A．$30. B．$180. C．$250. D．$360.
答案与解析：B 考查数字计算。根据Woodwork部分中的“Time: Mon. 5 pm — 7 pm”可知，该课程每周一开一次课；根据该部分中的“$30 per lesson”可知，每次课程要花费30美元；根据该部分中的“Length: 12 weeks”可知，该课程持续12周，即12次课。由此可知，上全部课程需要$30×12＝ $360，上一半的课程需要180美元，故选B项。

[2019·潍坊市统一考试] When traveling on a budget, every dollar counts. Unfortunately, the cost of tickets alone can make a serious hole in your savings. Don't let that stop you from taking your dream vacation, though. According to Jeff Klee, CEO of CheapAir. com, there is a “sweet spot” to get the biggest bang for your buck.
“The most important rule is fairly obvious: don't wait until the last minute, as that rarely works out，” he said in a statement. “But beyond that, you also want to be careful not to buy too early.”
Still, that's easier said than done. Finding the most
cost-efficient time to book is tough. Luckily, somebody did the math — so you don't have to. Data crunchers from the online travel agency CheapAir. com surveyed over 917 million fares to determine the day with the cheapest rates.
Here's what they found: while prices tend to stay the same between 320 and 106 days before a trip, they start dropping at the 105-day mark. That said, you might be tempted to book the
moment prices drop. But hold on! You'll save even more money by booking precisely 70 days before your trip. According to CheapAir. com, you can save 48 percent of the ticket's total cost by using this trick. After that date, airfares will begin to increase again. And don't even think about booking any later than 20 days ahead of time, as prices will be soaring.
So, what are you waiting for? Start planning your next dream vacation, and book accordingly. Your wallet will thank you — guaranteed.
体裁：说明文 题材：旅游 主题：如何购买便宜飞机票
【语篇解读】 本文是一篇说明文，介绍了购买便宜飞机票的方法和策略。
【难句分析】 Here's what they found: while prices tend to stay the same between 320 and 106 days before a trip, they start dropping at the 105-day mark.
分析：what引导表语从句，在从句中作宾语；while引导让步状语从句，意为“尽管”。
译文：这是他们所研究的结果：尽管价格在旅行前的106天到320天内保持不变，但是在105天这个关口价格就开始下降了。
4．When can we book our plane tickets to save the most money?
A．The later, the better. B．As early as possible.
C．105 days before our trip. D．70 days before our trip.
答案与解析：D 考查细节理解。根据第四段的内容尤其是第四句“You'll save even more money by booking precisely 70 days before your trip”可知，旅行前第70天预订机票节省的钱最多，故选D项。
