请大家帮分析句子,第1.2.3.4个 when 各修饰谁的,这是什么句呀?would be used这是什么时态?这句的主句
bagrit foresaw a time when computers would be small enough to hold in the hand,when they would be capable of providing information about traffic jams and suggesting alternative routes,when they would be used in hospitals to help doctors to diagnose illnesses,when they would relieve office workers and accountants of dull,repetitive clerical work.

Answer 1

是4个并列的定语从句,修饰开头Bagrit foresaw a time中的“time”
Bagrit预见了未来,届时计算机将小到可以拿在手中；能提供交通堵塞的信息（“they”指代前一个从句中的compumters）,并建议替代路线；能帮助医生诊断疾病；能将办公室职员和会计从无聊重复的工作中解放出来.
would be used,是被动式的过去时态,因为主句中foresaw是过去式,所以从句都要使用过去式,而computer是被人使用的,所以被动式be used
不知道我解释清楚了没有
