Throughout history, humans have moved around the Earth. Even before there were countries with borders, humans moved from region to region seeking a better life. Later, as nations were established, people continued to move. But in order for people to enter a country, they had to seek permission from the government of the country they were entering.These people came to be known as immigrants.Their movement was called immigration.

縱觀歷史，人類(lèi)一直在地球上移動(dòng)。 甚至在有邊界的國(guó)家之前，人類(lèi)就從一個(gè)地區(qū)轉(zhuǎn)移到另一個(gè)地區(qū)尋求更好的生活。 后來(lái)，隨著國(guó)家的建立，人們繼續(xù)遷徙。 但是為了讓人們進(jìn)入一個(gè)國(guó)家，他們必須向他們進(jìn)入的國(guó)家的政府尋求許可。這些人被稱(chēng)為移民。他們的運(yùn)動(dòng)被稱(chēng)為移民。

RAZ有嚴(yán)密的分級(jí)體系：根據(jù)全文詞匯數(shù)、高頻詞詞匯數(shù)與比例、低頻詞詞匯數(shù)與比例、句子長(zhǎng)度、句子復(fù)雜度、句式、插圖信息量、思想深度、主題等多個(gè)角度，將整個(gè)閱讀體系分為aa，A-Z共27個(gè)級(jí)別。

RAZ旨在幫助孩子找到適合孩子水平的級(jí)別，通過(guò)在同一級(jí)別下的大量閱讀逐步提高孩子的閱讀能力。

RAZ按難度分為27個(gè)級(jí)別，AA—C這4個(gè)級(jí)別對(duì)應(yīng)幼兒園階段; D—J這7個(gè)級(jí)別對(duì)應(yīng)美國(guó)小學(xué)一年級(jí);K—P這6個(gè)級(jí)別對(duì)應(yīng)美國(guó)小學(xué)二年級(jí);Q—T這4個(gè)級(jí)別對(duì)應(yīng)美國(guó)小學(xué)三年級(jí);U—W這3個(gè)級(jí)別對(duì)應(yīng)美國(guó)小學(xué)四年級(jí);X—Z對(duì)應(yīng)美國(guó)小學(xué)五六年級(jí)(相當(dāng)于國(guó)內(nèi)高中畢業(yè))。
