Solution:

• The task is to highlight the sentences. In the provided grid, the characters form sentences when read column by column from right to left.
• The first sentence is: 你家有几口人? (How many people are in your family?)
• The second sentence is: 他住在北京。 (He lives in Beijing.)
• The third sentence is: 叫名在谁星话 (This does not form a coherent sentence in standard Chinese.)
• The fourth sentence is: 王字是哪期号 (This does not form a coherent sentence in standard Chinese.)
• The fifth sentence is: 星。他九岁。儿?码 (This does not form a coherent sentence in standard Chinese.)
• Based on the instruction "Highlight the sentences." and the common structure of such exercises, the meaningful sentences are likely the first two columns from the right. The diagonal line seems to indicate that the remaining columns are not to be considered or are part of a different exercise.

Highlighted Sentences:

• 你家有几口人?
• 他住在北京。

Answer: The sentences to highlight are "你家有几口人?" and "他住在北京。".
