takes about one hour and ten minutes.”属于不“完整的表达”吗？
《初中英语预备课程》（Starter）(译林出版社2013年7月第2版2020年6月第8次印刷) P48：2 It takes about one hour and ten minutes.（page35）
从以上可以看出编者认为“ It takes about one hour and ten minutes.” 是不完整的。
读到此处，大家还认为这句话不完整吗？是否还坚持编者认为“完整的表达It takes us about one hour and ten minutes to get there.”？
大家应该有自己的判断：在上面的语言环境中，只能用“It takes about one hour and ten minutes.” 这句话是完整的，句中的“it”不是形式主语，而是代指上句话中的“travel there by train”。实际上这两句话可以利用编者认为“完整的表达”的句型合并为一句话：It often takes my parents and me about one hour and ten minutes to travel there by train.
其实在take 作“花费时间等”讲时，可以构成四个常见的不同句型，详见A.S. Hornby原著Margaret Deuter Oxford 策划编辑Advanced Learner’s English-Chinese Dictionary《牛津高阶英汉双解词典》（第九版）(商务印书馆 2018年3月第5版) P2201：TIME 时间 29 [transitive, no passive, intransitive] to need or require a particular amount of time 需要……时间；费时
~ sth The journey to the airport takes about half an hour. 到机场大约需要半小时。（笔者注：It takes about one hour and ten minutes.即属于该句型。）
~ sth to do sth It takes about half an hour to get to the airport. 到机场大概需要半小时。
That cut is taking a long time to heal. 那伤口需要很长时间才能愈合。
~ sb sth (to do sth) It took her three hours to repair her bike. 她花了三个小时修理自行车。（笔者注：该句型即属于编者认为的“完整的表达”。但不能因此就说上面两个句型就不是完整的表达。笔者认为这上面三个句型和下面的句型都是完整的表达，但需要根据具体语言环境选用不同的句型）
~ sth for sb to do sth It'll take time (= take a long time) for her to recover from the illness. 她的病需要长时间才能痊愈。（笔者注：该句型可以直接转化成上面的句型，即It'll take time for her to recover from the illness.=It'll take her time to recover from the illness.）
另外， Michael Swan 在Practical English Usage (Fourth Edition 2016) P602也给出了这样的句型：602 take： time
We can use take to say how much time we need to do something. Five structures are common.
1 The person is the subject:
person + take + time + infinitive
I took three hours to get home last night.
She takes all day to get out of the bathroom.
They took two hours to unload the ferry.
2 The activity is the subject:
The drive took me three hours. Gardening takes a lot of time.
Unloading the ferry took them two hours.(笔者注：It takes about one hour and ten minutes.即属于该句型，因为person可以省略。)
3 The object of the activity is the subject:
object of activity + take (+ person) + infinitive
The ferry took them two hours to unload.
This house will take all week to clean.
4 Preparatory it is the subject:
It + take (+ person) + time + infinitive
It took me three hours to get home last night.
It takes ages to do the shopping.
5 Before/until is used:
It + take (+ person) + time + before/until.
It took us six weeks before/until we got the house clean.
It took a long time before/until she felt comfortable in her new school.
从以上可知：“It takes about one hour and ten minutes.属于《牛津高阶英汉双解词典》（第九版）中的”take sth”句型；属于Practical English Usage中的“activity + take (+ person) + time”句型，的的确确是“完整的表达”，只是使用的语言环境不同而已。
