There are many famous foreign novels such as Jane Eyre, The Thorn Birds, The Little Prince, The Old Man and the Sea, Les Miserables, Pride and Prejudice, but novels such as Jane Eyre, The Little Prince and The Count of Monte Cristo will all appear in teaching, and reading will help you.
Personally, I prefer Sanmao's Sahara desert, gentle nights, crying camels, how many flowers fall into a dream, and the rainy season is gone forever. Sanmao's words always have a faint warmth, which makes people feel nostalgic and greatly improves their cultural literacy.
Personally, there is not much research on poetry. I have only seen Spring among the Stars by Bing Xin and Birds by Tagore, both of which are quite classic.
The following is a youth novel that I personally recommend to you, which is well worth reading.
Jing Ke and Jing M.Guo's "How many flowers fall in a dream", the summer solstice has not yet arrived, and sadness merges into a river. Well, if you are a girl, read Xue Xiaochan's book. Personally, I think she is a good writer, and her writing is very interesting. Recommend her "Actor" and "Fireworks are Cold". Xue Xiaochan described his impressions of cities, colors, operas and plants with delicate brushstrokes.
