Dutch and English have the same origin, they both belong to the indo-european language group. But of course this origin is way in the past. Dutch is more similar to German then English; Dutch and German words are often quite similar, and also the grammar is not much different. However, from a chinese point of view Dutch and English are quite similar; the differences between them are nothing compared to the diffences between Cinese and English.

Well, there are much Dutch words which are very similiar to English words. And also there are much words in Dutch, which come from the English language, pronounced and/or written the same. And there is also a few letters (and/or lettercombinations) in the Dutch alphabet, which you don't have in the English Alphabet, like: "ij". And another differences are the letter combinations, which you also don't have in English or pronounce totally different, like: "eu" Or you also have "ei", which in the English language you pronounce as: "ay", like in "either", while in Dutch you pronounce the "ei" like the English word: "Eye"), and the "ij", also pronounced as: "ai", like the English word: "Eye". Another difference, is the grammar, the grammar is really different, for example: Words in Dutch sentences in the past tense must be ending with: -de -den or starts with: Ge- (For example; "Zij studeert" in past tense is: "Zij studeerde." or "Zij heeft gestudeerd." -- Both means: She Studied.) While words in English sentences in the past tense must be ending with: -ed "She studies." will be: "She studied." -> She Studi-ed- or: "She works." will be: "She worked." -> She work-ed- There is also: "Heeft" wich means "Has". And with "heeft" in the Dutch language before the verb, you have to add "Ge-" before the verb, while you don't have to add anything in the English language if you put "Has" before the verb. So in Dutch: "Ze heeft gestudeerd." -> -Ge-studeerd While in English it's still the same: "She has studied." And so there are a few other differences between the English and Dutch grammar too.

Do they have the same origin? anyway compared with Chinese,they are still close,Thanks.

Quite a lot, actually. They are different (albeit related) languages after all.
