48 countries. Only Chinese and Japanese use Chinese characters, and Japanese uses them in combination with two syllabic alphabets.
Tone languages:
Most languages of sub-Saharan Africa are tonal. The vast majority of Niger–Congo languages, such as Ewe, Igbo, Lingala, Maninka, Yoruba, and the Zulu, have register-tone systems. Possibly all Nilo-Saharan languages have register-tone systems. All Khoisan languages in southern Africa have contour-tone systems.
Some of the native languages of North and South America are tonal, notably many of the Athabaskan languages of Alaska and the American Southwest (including Navajo), and especially the Oto-Manguean languages of Mexico. Among the Mayan languages, Yucatec (with the largest number of speakers), Uspantek, and one dialect of Tzotzil have developed simple tone systems.
Some European languages also have tone systems: Norwegian, Swedish, Latvian, Lithuanian, Serbo-Croatian, some dialects of Slovene, and Limburgish have simple tone systems generally characterized as pitch accent. Other Indo-European tonal languages, spoken in the Indian subcontinent, are Punjabi, Lahanda, Rabinian and Western Pahari.
As you can see from the (partial) listing of languages which have tonal systems, native language has not a thing to do with why children do well in school. The idea that it does, the idea that some people have to "work harder" to comprehend their native language, is simply exoticism. The reasons some groups of children do better at school than others aren't genetic or linguistic, but sociological.Before the 1900s many people believed that so-called 'primitive peoples' would have primitive languages, and that Latin and Greek-- or their own languages-- were inherently superior to other tongues.
In fact, however, there is no correlation between type or complexity of culture and any measure of language complexity. Peoples of very simple material culture, such as the Australian Aborigines, are often found to speak very complex languages.
Obviously, the size of the vocabulary and the variety and sophistication of literary forms will depend on the culture. The grammar of all languages, however, tends to be about equally complex-- although the complexity may be found in different places. Latin, for instance, has a much richer system of inflections than English, but a less complicated syntax.
As David Crystal puts it, "All languages meet the social and psychological needs of their speakers, are equally deserving of scientific study, and can provide us with valuable information about human nature and society."
http://www.zompist.com/lang9.htmlThe idea that one language can be inherently harder than another language is not supported by linguistic research. Were this the case, it would logically follow that children whose mother tongue is hard would develop language skills later than children with easy mother tongues. Studies on this subject have shown that children of all languages develop language competency on average at about the same rate.
http://www.chinese-lessons.com/cantonese/difficulty.htmDo you have to "think hard" when you chose among "I, me, my, mine or go, went, going, gone, have gone, has gone, had gone" or whether to use "The" or "a" or nothing in front of a noun?
You don't "think" at all. Nothing like this exists in Chinese, but likewise, they don't have to "think" when they hear tones or chose which tone to use with which phoneme.
And FYI, this is a pictograph:


Pictograms and pictographs *represent* themselves. The man IS a man.
This is not a pictograph OR pictogram. It's abstract writing, and unless you are taught, you won't know what it symbolizes. There is no "picture" there.
