1 . My brother can go for a picnic so he cant go fishing

->          so -> but 

bởi vì so là chỉ ra kết quả, còn but là chỉ sự trái ngược 

2 . We will stay at home if it rain tomorrow .

->          rain -> rains

Bởi vì He/She/It + V/s/es

3 . Tom have visited London twice 

->             have -> has

Bởi vì He/She/It + has

4 . What do you like the Animals programmes ? Because I love animals .

Bởi vì trong câu có chữ because là dùng để giải thích một lý do nên ta ko dùng what mà dùng why.

linda and her friends will build sandcastles in the beach => on
we will goes to tha beach next sunday => go
where will you go for a picnic ? - next weekend => when
he may explores the caves => explore
I think he fly home this sunday => will fly

Đây là đáp án và lời giải thích nha bạn 

Linda and her friends will build sandcastle in the beach .

giải thích :Từ sai ở đây là in bởi vì theo công thức đối với từ in thì sẽ dùng cho những địa điểm lớn ví dụ như nước Việt Nam ,hay Trung Quốc gì đó sẽ thành in Vietnam .Từ at dùng cho những địa điểm cụ thể ví dụ như nhà thì sẽ thành at home .Từ on thì sẽ dùng cho những địa điểm nhỏ vì dụ như biển thì là một địa điểm nhỏ ,không lớn hơn nước sẽ dùng on .Biển chỉ là một địa điểm nhỏ nên ta chỉ được dùng từ on mà câu này dùng in nên sai nhé !

We'll goes to tha beach next sunday .

giải thích :Từ goes sai vì theo ngữ pháp danh từ ,we ,you ,they ,I sẽ dùng go còn she với he mới dùng goes .

He may explores the caves .

giải thích :Từ explore không có S nha 

I think he fly home this sunday .
