Answer 1

his picture is___(beautiful)than that one.

What's the_____(high)of the Oriental Pearl Tower?

My uncle is good at______(drive)
答案： driving
be good at 中的at 是介词后跟动词ing形式

She______(hold)her breath before she dived into the lake.
答案： held
解析： dived 用的是过去式，看看出是一般过去时

Lions are_____(danger),so you should not go near them.
答案： dangerous
be + 形容词 dangerous 构成系表结构

答案： to keep
解析： it's + 形容词+ for sb. + to do sth.

Bicycles are still very_____(use)to students.
答案： useful 有用的
解析：be + 形容词

Our classroom is on the_____(two)floor.
答案：second
解析： the + 序数词； the the second floor 在二层

Answer 2

more beautiful （than前面加比较级）
height（of前跟名词）

driving（be good at doing固定词组）
held（有before跟过去式）
dangerous（形容词）
to be（It's加形容词加for+sbtodo）
used（be used，被动语态）
second（我们教室只可能在第二楼而不是两楼）
Ps：难得这么认真，楼主觉得好就选了吧

Answer 3

2 height 名词形式,高度;
3held 过去式;
4 dang'erous 危险的,用形容词;

dangerous 形容
to keep “to be”型
