编写一个算法，将字符串列表作为输入并返回包含两个或更多单词的字符串列表。
def two_words(string_list): 
  result = [] 
  for s in string_list: 
    if len(s.split()) >= 2: 
      result.append(s) 
  return result 

string_list = ["one","two","three","four"]

print(two_words(string_list))
# Output: ["two", "three", "four"]
[“one”, “two”, “three”, “four”]
