不是。I speak german（德语）, of course. At school (在中学) I had to learn two languages: 1. english (英语) and 2. french (法语) or latin (拉丁语). I've chosen french, but I'm far from knowing the language good enough, while my english is quite fluent. Because in english I had better training and I use it very often reading books. During their summer holiday a lot of Germans travel to Italy, some to Spain or to France. The British would prefer spain. (I prefer 中国). You see: their language skills usually are not on the same level in each language they've learned. Here on italki you meet people who want to learn other languages. Some of them are learning 4 or 5 of them. At the same time. Very few are able to do that. I'm not. And that doesn't mean 外国人 learn better and faster. Some Chinese speak several chinese dialects. You can compare this to speaking several european languages. 都是相似的？ English is connected to dutch (菏兰语), german and the scandinavian (挪威, 瑞典, 丹麦 的) languages. On the other hand there are relations to roman languages, like french. But without learning these languages they (英国人) are not able to understand much. To Spaniards （西班牙人） it will be easy to learn portugese （葡萄牙语） or italian （意大利语）, because these languages are closely related. Next to those would be french.

英語中存在大量來源於法語的辭彙。西元1066年，法國諾曼第公爵征服英格蘭，建立諾曼王朝。之後數百年，英格蘭為講諾曼語的王朝統治，大量法語詞彙進入英語。

打个比方,我听一个从德国来的交换学生说,她们学校里除了母语外,英语作为一种外语是必修的,还要从法语,西语等语言中选修一种第二外语(她选了法语),她大学要学的系还要再学一门第三外语,备选的有意语,日语等,而她选了意大利语.这是外国教育大纲的问题.中国因为学校里只教英语,要学别的语言还要自己到外面掏钱学,所以很多人都没这个条件或者没这个时间.还有,北美的美国和加拿大都是移民国家,有来自各国,各民族的人;而在欧洲,国家多,语言多,不怕没有练习的地方和对象;而且欧美人生活水平普遍很高,这也客观上使他们有条件去别的国家练习语言. 至于这些语言是不是相似,前面那位已经说得很清楚了,这些语言看上去相似,其实也就是单词拼写比较相似,绝对不是看上去那么容易学.但相似毕竟还是相似,所以掌握了一种语言对学习别的语言还是有很大帮助的.

都是相同的语系吧,向我们中国人学中国的八大语系,你要是愿意学,很容易都学全的.
