Specific details on what kind of rules would be carried out are still unknown to the public.Despite the growing popularity, bloggers and webcasters have been unpopular with publication institutions.In 2020, a series of cases involving bloggers who had dived into other people's privacy and written materials ruining others' fame urged the government to consider whether to require bloggers to use their real names when they log in.Webcasting without copyright and illegally “copying” products from copyrighted materials have also led government officials to consider starting a nationwide check of online video broadcasting, and allow only qualified websites to continue offering webcasts.1What can be the best title of the passage?

Despite countless warnings in recent years about the need to address a looming(逼近) hunger crisis in poor countries and a looming energy crisis worldwide, world leaders failed to think ahead. The result is a global food crisis. Wheat, corn and rice prices have more than doubled in the past two years. And oil prices have increased more than three times since the stavt of 2020. These food prices increases, combined with soaring energy costs, will slow if not stop economic growth in many parts of the world and will even undermine(破壞) political stability, as evidenced by the protest riots that have erupted in places like Haiti, Bangladesh and Burkina Faso. Practical solutions to these growing woes do exist, but we'll have to start thinking ahead and acting globally. So, what should be done？Here are three steps to ease the current crisis and avert(防止， 避免) the potential for a global disaster. The first is to scaleup(按比例增加，擴(kuò)大) the dramatic success of Malawi, a famineprone(遭遇饑荒) country in southern Africa, which three years ago established a special fund to help its farmers get fertilizer and highyield seeds. Malawis harvest doubled after just one year. An international fund based on the Malawi model would cost a mere $10 per person annually in the rich world, or $10 billion in all. Second, the US and Europe should abandon their policies of subsidizing(給補(bǔ)助金) the conversion of food into biofuels(生物燃料) Third, we urgently need to weatherproof(使防風(fēng)雨) the world's crops as soon and as effectively as possible. For a poor farmer, sometimes something as simple as a farm pondwhich collects rainwater to be used for emergency irrigation in a dry spellcan make the difference between a bountiful crop and a famine. The world has already committed to establishing a Climate Adaptation Fund to help poor regions, climateproof vital economic activities such as food production and health care, but has not yet acted upon the promise.The food crisis provides not only a warning but also an opportunity. We need to invest vastly more in sustainable development in order to achieve true global security and economic growth.4. Which of the following is the best title?A. How to End the Global Food Shortage.B. How to End the Global Disaster.C. How to Help the Farmers in the Poor Countries.D. How to Subsidize the Farmers to Increase Food Products.答案及解析： 4A。主旨大意題。文章主要講如何結(jié)束全球食物短缺，A能概括文章中的主要內(nèi)容。B、C、D都是文章中的一部分。5.
