你喜歡夏天嗎?

你好!
我是Alexandra. 我是二十二歲. 我要說,看和写中文.
我喜歡清天. 俄国有多冷天. 我有多熱天, 黃太陽和藍天.
你喜歡夏天嗎?
再見!

看中文 sounds a bit weird, as it is usually 讀 (read) not 看 (look)

我有多熱天, 黃太陽和藍天 for this part, the problem is that you are using 有 (have), so the sentence you type means "I have many hot days, yellow sun and blue sky"

for the ones highlighted green, the character you type is in Simplified Chinese, not Traditional Chinese

Hope this helps!
