Liu Tao's grandma giye we look her photo

当然不对
liu tao's grandma gives us her photo.
liu tao's grandma lets us to see her photo.

有问题。
应改为Liu Tao's grandma let me look at her photo.

Liu Tao's grandma lets us look at her photo.
or Liu Tao's grandma gives us her photo.
strusture:
let sb do sth;
give sb sth ; give sth to sb.

Liu Tao's grandma showed us her photo.
刘涛的奶奶给我们看她的照片。
给我们看用“give we look”翻译的有点硬。
平时多听多看，语感就出来了。

我觉得应该是Liu Tao's grandma let us watch her photo.

watch 是watch TV的watch，看的同时，包含欣赏的意思。

她奶奶让你们欣赏她的照片，我觉得这个意思最好。

GIVE更多的是表达给予的意思。
