Eng grammar

Q1
" I find Edward's exam skills useful. "
我知道一句句子唔可以同時有兩個verb
但我唔明白 點解useful 可以就咁寫係skills後面?

Q2
" I find Edward's exam skills which is useful for me. "
依句有冇錯?

Q3 假設我睇左一本書，我想係篇article到寫番我的睇法
係用I think 定係 I thought? 我唔係好知用咩tenses

Q4
Have you watched “Junior MasterChef Australia” before? This is an Australian
competitive cooking reality show. Children aged 8-12 are the contestants to join
this show. Although they are young, their performances showed that they are
talented cook and their cooking skills are even better than some adult cook.

我想問，Although they are young <<<用are岩唔岩
their performances showed that they are talented
cook and their cooking skills are even better than some adult cook. <<<依一句tenses有冇錯

唔該晒!!!!!!!!!!
