▲be expected to do sth 只表示被动，不表示主动，有时在汉语中没有从字面上翻译出被动来，只是为了符合汉语表达习惯而已，其隐含的意思仍是被动的。如：

Each man is expected to do his duty. 每个人当各尽其责。（意指：每个人都被期望要各尽其责）

You will be expected to work on Saturdays. 你们星期六要上班。（意指：人们指望你星期六上班）

The following are expected to come at 2:00. 下列人员应在两点钟到达。（下列人员被要求在两点钟到达。）

He is expected to remain in hospital for several more days. 他还需在医院多住几天。（意指：他被要求在医院多住几天）

One of the major banks has lowered its interest rates and the other banks are expected to follow suit. 有一家大银行已降低了利率，其他银行也准会照样做的。（意指：人们预计其他银行也会照样做→其他银行被人们预计到会这样做）

▲be determined to do sth 与上述用法不同，这里的 determined 已转化为形容词，意思是 with one's mind firmly made up 或 resolute（有决心的；意志坚定的；坚决的——表主动意义）。如：

She was determined that he should study music. 她下决心要他学习音乐。

A really determined person never gives up. 一个真正有决心的人绝不会放弃。

They were determined to press their case at the highest level. 他们决定把他们那事向最高层反映。

比较下面两句在含义上的差别：

I have determined to go abroad. 我已决定出国。

I am determined to go abroad. 我已下定决心要出国。

在前一句里，determine 是界限动词，强调一时的动作；在第二句里，determined 用作形容词，说明的是一种状态，即一种坚定不移的决心。
