While we ... (have) tea, it ... (start) to rain.

While we were having tea, it started to rain.

i see a green tree and a red dog near it.

this red dog can't talk.

little tanya can't read.

she can speak.

help! help! he is not strong and not brave. his face is ugly. he has  got a white nose. he can't swim, sing and run. he lives in the field.
