题目内容

3．China will make a great difference in promoting multinational joint development，the"Belt and Road"policies ________．（　　）

	A．	accelerated		B．	accelerating
	C．	to accelerate		D．	having accelerated

分析中国将在提升跨国联合合作方面即"一带一路"政策上的加速发展产生深远影响．

解答答案：A．
此处的the"Belt and Road"policies 指的是国家在2015年推出的"推动共建丝绸之路经济带和21世纪海上丝绸之路的愿景与行动"这一国家政策．make a difference意为："有影响，产生作用"；promote sth accelerated是属于动词+名词=过去分词短语，构成的结构，即过去分词短语做宾语补足语，意思是"促进这一跨国联合合作关系--一带一路政策的加速发展．"

点评理清句子之间的逻辑关系以及分析句子的成分是解决这类题的一个关键．尤其是一些时政知识的积累也是很重要的．

The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid --- we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard（蜥蜴）native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we’ll need huge feet that we could bring up to our ears in order to create adequate “hitting.”

But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now if the surface of the water is hit hard enough, particles（粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick liquid of cornflour.

Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink --- and take a shower afterward!
