材料:影响德国海军发展的因素既有德国民族,包括威廉二世皇帝(1888年—1918年在位)本人在内的建立海军的热情,也有德国经济发展带来的必然性,而且还有海军战略思想转变的物质和技术前提。而威廉二世的不懈努力更是促成了德国海军战略的转史。扩建海军是威廉二世世界政策的核心内容,也是推行世界政策的重要工具。因此,随着海军战略的转变以及海军的发展,德国大肆进行殖民扩张。威廉二世时期的海军政策给德国带来了严重后果,造成了灾难性影响。

Have you ever run into a careless mobile phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new “species(物种)” of human has kept rising, they have been given a new name˗˗˗˗phubbers.
Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight(聚光灯). In the short film, phubbers with different social identities always put themselves in their phones. A doctor plays with his mobile phone while letting his patient die, a pretty woman takes selfie(自拍照) in front of a car accident site(场地), and a father loses his child without knowing about it while using his mobile phone. A chain of similar events finally leads to the destruction(毁灭) of the world.
Although the ending sounds overstated(夸张), the damage(损害)that phubbing can bring is real.
Your health is the first to bear(承受) the effect and result of it. “Constantly(不断地) bending(使弯曲) your head to check your telephone could damage your neck,” Guangming Daily quoted(引述) doctors as saying, “the neck is like a rope that breaks after long-term stretching(伸展).” Also, staring(盯着) at telephones for long periods of time will damage your eyesight gradually, according to the report.
But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions(团聚)with family or friends, many people tend to stare at their telephones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.
It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their telephones in broad daylight.
—Yes, I can.
