一、例句
Netflix has yet to lay to rest a long-standing concern that its rising international revenues will not offset slowing subscriber growth in America, its biggest market. (改编自 The Economist)
二、句子解析
这句话的意思是：奈飞尚未消除一个长期存在的担忧，即其不断上升的国际收入无法抵消其最大市场美国用户增长放缓的影响。
这句话选自最新一期《经济学人》Business 版块的 Schumpeter 专栏，文章讲了奈飞的商业表现，并预测奈飞在新冠疫情结束之后仍然会保持行业领先优势。
这句话的正常语序是：
Netflix has yet to lay a long-standing concern that...to rest.
但由于 that 从句过长，所以原句将 to rest 前置，就成了
Netflix has yet to lay to rest a long-standing concern that...
这是英文中更惯用的写法，更易读。
句中的 have yet to do something 是个地道的短语，《剑桥英语词典》中的释义是：used for saying that something has not happened or been done up to the present time, especially when you think it should have happened or been done. 简单来说，have yet to do something = have not yet done something。
所以上面这句还可以写作：
Netflix has not laid to rest a long-standing concern that...
当我们想表达“某人尚未消除一个长期存在的担忧”时，就可以使用“X has yet to lay to rest a long-standing concern that Y.”这个实用的句式。
三、句式临摹
临摹句子：
Netflix has yet to lay to rest a long-standing concern that its rising international revenues will not offset slowing subscriber growth in America, its biggest market.
提炼句式：
X has yet to lay to rest a long-standing concern that Y.
注意：
1）如果 X 是复数，谓语动词 has 需要变成复数；
2）Y 是个完整的句子，具体解释前面的 a long-standing concern。
造句示范：
a）Pharmaceutical companies in the US have yet to lay to rest a long-standing concern that minorities, in particular African Americans and Hispanics, are less willing to participate in clinical research than non-minorities.
b) 场景：很多创业公司的模式是先拿投资人的钱，通过烧钱去获取用户。有的公司获取用户后可以保证一定的用户留存，甚至已获取的用户会推荐新用户，但有的公司获取的用户会很快流失。
The startup has yet to lay to rest a long-standing concern that its burn rate will not translate into user retention and improved user referral.
(Burn rate is the rate at which a company is losing money. It is typically expressed in monthly terms. E.g., "the company's burn rate is currently $65,000 per month." In this sense, the word "burn" is a synonymous term for negative cash flow. It is also measure for how fast a company will use up its shareholder capital.)
