37、o answer because there are many factors to take into consideration。 Firstly， in a first language the differences are unimportant as people learn their mother tongue naturally， so the question of how hard a language is to learn is only relevant when learning a second language. A native speaker of Spa
38、nish， for example, will find Portuguese much easier to learn than a native speaker of Chinese， for example， because Portuguese is very similar to Spanish, while Chinese is very different, so first language can affect learning a second language。 The greater the differences between the second language
