结合语境可知，say something rude已经是过去的动作，答句表示“我宁愿我没说那样的话”，表示与过去事实相反的情况，would rather后应用have V-ed，故选D项。

所以，从句的完整表达方式应该是if I had devoted more energy to my study instead of being crazy about Interact games.此时，可以省去if，提前had。

故选B。

（2017·江苏卷）A new commodity brings about a highly profitable, fast-growing industry, urging antitrust（反垄断）regulators to step in to check those who control its flow. A century ago, the resource in question was oil. Now similar concerns are being raised by the giants（巨头）that deal in data, the oil of the digital age. The most valuable firms are Google, Amazon, Facebook and Microsoft. All look unstoppable.Such situations have led to calls for the tech giants to be broken up. But size alone is not a crime. The giants’ success has benefited consumers. Few want to live without search engines or a quick delivery. Far from charging consumers high prices, many of these services are free (users pay, in effect, by handing over yet more data). And the appearance of new-born giants suggests that newcomers can make waves, too.But there is cause for concern. The Internet has made data abundant, all-present and far more valuable, changing the nature of data and competition. Google initially used the data collected from users to target advertising better. But recently it has discovered that data can be turned into new services: translation and visual recognition, to be sold to other companies. Internet companies’ control of data gives them enormous power. So they have a ＂God’s eye view＂ of activities in their own markets and beyond.This nature of data makes the antitrust measures of the past less useful. Breaking up firms like Google into five small ones would not stop remaking themselves: in time, one of them would become great again. A rethink is required — and as a new approach starts to become apparent, two ideas stand out.The first is that antitrust authorities need to move from the industrial age into the 21st century. When considering a merger(兼并), for example, they have traditionally used size to determine when to step in. They now need to take into account the extent of firms’data assets(资产) when assessing the impact of deals. The purchase price could also be a signal that an established company is buying a new-born threat. When this takes place, especially when a new-born company has no revenue to speak of, the regulators should raise red flags.The second principle is to loosen the control that providers of on-line services have over data and give more to those who supply them. Companies could be forced to consumers what information they hold and how many money they make form it. Governments could order the sharing of certain kinds of data, with users’ consent.Restarting antitrust for the information age will not be easy. But if governme nts don’t wanta data economy controlled by a few giants, they must act soon.1.Why is there a call to break up giants?A. They have controlled the data market.B. They collect enormous private data.C. They no longer provide free services.D. They dismissed some new-born giants.2.What does the technological innovation in Paragraph 3 indicate?A. Data giants’ technology is very expensive.B. Google’s idea is popular among data firms.C. Data can strengthen giants’ controlling position.D. Data can be turned into new services or products.3. By paying attention to firms’ data assets, antitrust regulators could ____________.A. kill a new threatB. avoid the size trapC. favour bigger firmsD. charge higher prices4. What is the purpose o f loosening the giants’ control of data?A. Big companies could relieve data security pressure.B. Governments could relieve their financial pressure.C. Consumers could better protect their privacy.D. Small companies could get more opportunities.【文章大意】本文主要讲的是信息时代的信息数据的垄断现象。
