Answer 1

1.花费.去做某事.it takes/costs ...(time or money or efforts) to do sth.这个算固定用法了
2.建议把划线后的调整一下顺序.the lengthening of human life possible.
make sth.possible.这里只是sth.那段比较长而已,所以放后面了.
翻译：未来科学发现多大程度上能使延长人类寿命成为可能?
3.非谓语动词的主动形式表被动意义
在动词bear(适宜于),deserve(应受到),need(需要),require(需要),stand(忍受),want(需要)等词的后面,动名词用主动形式表示被动意义,其含义相当于动词不定式的被动形式.
The house needs repairing（to be repaired）．这房子需要修理.
His sufferings don't bear thinking about.
他受的苦难简直不堪回首.
The desk needs repairing.课桌需要修理.
The flowers want watering.花需要浇水.
The man deserves punishing.他这个人是罪有应得.
4.It is 表命令建议等的词(suggested,ordered,required,proposed,demanded,requested,insisted等) +从句,从句中用should +动词原形 （should可以省略）表虚拟.
5.少了一个词.
