【解析】

本文讲述了一些发明。1895年，一位名叫威廉·伦琴的德国教授发现了x射线。电话是由亚历山大·格雷厄姆·贝尔发明的。电视机是由苏格兰发明家约翰·逻辑·贝尔德在1926年发明的。1946年，美国的两位工程师普雷斯帕·J·普雷斯帕发明了电脑。

1.细节理解题。根据“X-rays were discovered in 1895 by a German professor called Wilhelm Roentgen”1895年，一位名叫威廉·伦琴的德国教授发现了X射线,可知是1895年，故选B。

2.细节理解题。根据“The telephone was invented by Alexander graham Bell, a doctor and speech teacher for the deaf.”可知此处是“Alexander graham Bell”发明的电话，故选B。

3.推理判断题。A. Roentgen was a German.伦琴是个德国人；B. Bell was a doctor and speech teacher for the deaf.贝尔是一名医生和聋哑人的语言教师；C. The electronic television was invented in 1926.电子电视是在1926年发明的；D. The small computer was produced for personal use in 1971这台小型计算机是在1971年生产出来供个人使用的；根据“X-rays were discovered in 1895 by a German professor called Wilhelm Roentgen”可知是德国人，排除A；根据“The telephone was invented by Alexander graham Bell, a doctor and speech teacher for the deaf.”可知贝尔是聋哑人的医生和语言教师。此题是对的，排除B；根据“Later, in 1971, the small home computers were first produced for personal use.”可知这台小型计算机是1971年生产的供个人使用的。此选项是对的，排除D；根据“The television was invented in 1926 by John Logic Baird”可知不是今天的电子电视，故选C。
