The worker strikes in France for protesting against the plan to increase retirement age are escalating into a Europe-wide social crisis.

The escalating strike by french people to protest against higher retirement age is turning into a social crisis in Europe.

-----------------法国人为抗议延长退休年龄而不断升级的罢工事件，正演变为一场欧洲社会危机。-------------------- This Chinese sentence is grammatically incorrect. It's better to reword it as: 法国人因（政府）提高退休年龄而导致并不断升级的罢工事件正演变为一场（整个）欧洲的社会危机。 The escalating French stikes caused by the government's raising the retirement age have turned into a social crisis for the whole Europe. 1) 为 + verbal phrase1 + 而 +verbal phrase2 means doing 2 for the pursose of 1, so the original sentence is wrong. 2) You cannot say 延长...年龄. You 延长 something that' s lengthwise and so has a length in itself, but not something that's only a dot, nor a spot ( you can enlarge a spot). A prvailing phrasing in our press is 延迟退休年龄, this maybe feels a bit better, but not yet good, though, in my humble opinion. You can say 延迟 doing something, but you cannot 延迟 something.

法国人为抗议延长退休年龄而不断升级的罢工事件，正演变为一场欧洲社会危机。 French protests over plans to increase the retirement age are escalating and there are more strikes, this is slowly becoming a pan-european crisis.
