News Report 2  快餐的上餐速度正在变慢

Q3： Fast food turns out isn’t quite as fast as it used to be。 A new study finds that MacDonald posted its slowest drives through times since this survey was first conducted fifteen years ago。 As MacDonald’s， customers were spent on average three minutes and nine seconds from the time they placed their orders until they received their food。 That‘s about ten seconds more than the industry average and a lot slower than a decade ago， according to the study， which was commissioned by QSR， an industry trade publication。 And MacDonalds wasn’t alone in slowing down。 Other chains also saw their drive through performance slowing down。Q4： Among the reasons for the slower service， today there are more choices on the menu， and the products themselves are more complex and take longer to prepare。 Speed， of course， is essential to the drive through experience， and drive throughs are hugely important to chains such as MacDonalds， Burger King， and Tucle Bell。 Usually， the drive through accounts for sixty to seventy percent of all business that goes through a fast food restaurant， notes Sam Ochers， editor of QSR。 Of course， consumers also want their orders prepare correctly and on that score， Ochers says accuracy is still really high。

Q3： What is the news report mainly about？

Q4： What has slowed down MacDonald‘s drive through service？

浏览四个选项，从选项中的fast-food service，customer satisfaction，McDonald’s，competition等词可推测，此题与快餐行业的发展现状有关，如顾客满意度、快餐业的竞争等。题干问的是新闻的主要内容是什么。新闻中提到，一项QSR的新调查发现，快餐的上餐速度并不像以前那么快了，并举出麦当劳等多家快餐巨头的例子来具体说明上餐速度变慢的原因。由此可知，新闻主要是关于快餐服务行业的一项调查，故答案为A。B项(快餐行业的顾客满意度)、c项(麦当劳的新商业策略)和D项(快餐行业的竞争)在新闻中均未提及，故排除。

浏览四个选项，从选项中的customers’higher demands，inefficiency of employees和increased variety of products等词可推测，此题与快餐行业上餐速度变慢的原因有关。题干问的是麦当劳上餐速度变慢的原因是什么。新闻中间部分提到，上餐速度变慢是因为如今菜单上菜品的种类更加丰富多样，而且产品本身更复杂，需要更长的准备时间，故答案为C。A项(顾客要求更高)、B项(雇员效率低)和D项(顾客人数增长)在新闻中均未提及，故排除。
