问几道英语选择题，原因也请说明一下，谢谢

1.Since it is too late to change my mind now, I am ________ to carrying out the plan. [A] obliged [B] committed [C] engaged [D] resolved 2.When travelling, you are advised to take travellers’ checks, which provide a secure ________ to carrying your money in cash. [A] substitute [B] selection [C] preference [D] alternative 为什么不能是A?

Answer 1

1、D
be
obliged
to
do
sth
有义务做sth
不得不做
be
committed
to
致力于
委任于
be
engaged
in
参与
从事
忙于
be
resolved
to
do
=
be
determined
to
do
决心做sth
翻译:既然我现在改变想法为之已晚，我决定坚决执行这个计划
2、D
辨析
substitute
作替代，代替
普通用词，范围比较广
alternative
虽然也有替代的意思，但是更强调交替，或者二者选一这种情况
根据题中
旅游时两种支付方式:by
check
支票支付
in
cash
现金支付
所以侧重两者之间的选择
注意alternative
to
carrying
your
money
in
cash中to是介词，连接另一种支付方式
