英语动词短语疑问
I doubt whether he can ____ his efforts much longer as he looks very tired.
A.keep up B.keep on C.keep back D.keep from
我选的是B答案是A 为什么?
In the reading room,we found her _____ at a desk,with her attention _____ on a magazine.
A.sitting; fixing B.seated; fixed
C.seated; fixing D.sitting; being fixed
第一空为何是seated而不是stting?
When he got off the bus,he found his pocket _______.
A.stolen B.picked C.gone D.lost
A C D为什么不对?

1.A keep up 继续,而keep on持续,一直做
2.第一空填sitting 和seated都可以,作宾补,但第二空必须填fixed也作宾补表示被动.with 和它后面的构成一个复合结构作伴随状语,fix one's attention on sth"把注意力集中在....上"所以attention 和fix 之间是被动关系.
3.picked指被人掏过,用其它三个都指衣兜不见了.

答案AB里选,主要表达保持努力
keep on严格表示“不断(老是)做某事”的意思,强调动作连续不断,每隔一会儿发生
例如:John always kept (on) asking questions.约翰总是问个不停.News of successes keeps (on) pouring in.捷报频传.
keep up则是 坚持,保持
那么言下之意他肯定是一直在努力的状态,所以我猜怀疑他能坚持多久
而且effort来说,keep up保持努力不松懈这样一种状态,词组.也是用的比较多的
2seated 和sitting都是对的,没说stting不能用
seat动词用法只是被动形态表主动=sit罢了
其次her attention was fixed on a magazine
伴随状语,就是with her attention fixed on a magazine省略掉be动词
也就是说如果排斥seated的话,那就只能选错了.
3这里没有其他表变化的词,只有go
另外,go后接形容词通常表示的结果(见上例),在个别搭配中也表示现状:go hungry 挨饿,go naked 光着身子
主要指一种由强到弱或由好到坏的变化(可用于人或事物),
其次change加名词,而且最好是change into silence,否则意思不对
4我的口袋掉东西了
A口袋糟窃了,没错,但是有了lost更好,因为没上下文说口袋是自己粗心掉了,还是我怀疑有小偷干的
B关键词his,他发现他捡到了自己的口袋,要么把his拿掉
C这里也是丢失,但略有不同,一般说口袋里的东西丢失了
lost比gone范围大,gone是指东西离他而去,不在他身上了,(go的意思很形象)
