anticipate和expect的区别在哪里?

anticipate和expect的区别在哪里?
这两个动词都表示预期某事将发生,但有所不同.在意思上,anticipate所预期的一般都指可喜的事,expect则不一定.
We anticipate (or:expect) our products will be a quick seller in your market.
The firm expects heavy losses this year.（一般不用anticipate）
在结构上,除两个动词都可以用名词及that从句为宾语外,anticipate后面可接动名词,不可接不定式,expect则可接不定式,不可接动名词.
We anticipate shipping the goods next week = We expect to ship the goods next week.我们期望下周装货.
expect还可接"名词或代词+不定式"构成的复合宾语,anticipate则不可.
正：We expect the shipment to arrive in a few days.我们预期装运的货物将于日内到达.
误：We anticipate the shipment to arrive in a few days.
但是我遇到一道题如下：
As the goods are ready for shipment,we___your L/C to be opened immediately.
A.hope B.anticipate C.await D.expect
我选了D,但是答案给的是B,这似乎跟以上所说的用法冲突了.
