【正确答案】：
NATIVE WORDS ARE THOSE WORDS BROUGHT TO BRITAIN IN THE FIFTH CENTURY BY THE GERMANIC TRIBES, KNOWN AS ANGLO-SAXON WORDS. THEY ARE SMALL IN NUMBER, BUT FORM THE MAINSTREAM OF THE BASIC WORD STOCK AND STAND AT THE CORE OF THE LANGUAGE. THEREFORE NATIVE WORDS ARE CHARACTERIZED WITH "NEUTRAL IN STYLE" AND "FREQUENT IN USE" ALONG WITH THE FOUR FEATURES OF BASIC WORD STOCK. THE LOAN-WORDS, LARGE IN QUANTITY, HAVE ENRICHED THE ENGLISH VOCABULARY, BUT CAN NOT CHANGE THE BASIC STRUCTURE OF THE ENGLISH LANGUAGE, GRAMMAR FOR EXAMPLE.
【题目解析】：本题考查本族词与借词的关系。本族语词是公元5世纪由日耳曼部落带入英国的，又称盎格鲁-撒克逊词语。他们数量不多，但却构成了英国的基本词汇，是英语词汇的核心部分，形成了英语基本词汇的特点。除了之前提到的英语基本词汇的共同特点外，本族语词还有另外两个特点：文体上中性和使用频繁。外来词数量多，丰富了英语词汇，但不能改变英语语言的基本结构，如语法。
