Hi Dinghui! The difference between "Do you know?" and "Did you know?" lies in their tense and usage: 1. Do you know? This phrase is in the present simple tense. It is typically used to inquire about someone's current knowledge or understanding of a particular fact, topic, or situation. It is a general question that does not imply any specific time frame. For example: "Do you know where the library is?" "Do you know how to speak Spanish?" 2. Did you know? This phrase is in the past simple tense. It is used to ask if someone was already aware of a particular fact or information, usually with the implication that the information is surprising or new to the listener. It often introduces interesting or unexpected information. For example: "Did you know that the Earth is round?" "Did you know that elephants can communicate over long distances using infrasound?" Hope it helps! :)

Hi Lisa! Your sentences are mostly clear, but maybe it sounds more natural if you say it this way: "It seems you like me, want to protect me, and take care of me. How come?"

1. Yemen has been facing one of the worst humanitarian crises in the world. There are millions of people in dire need of food, clean water, and medical assistance. 2. The conflict in Yemen has resulted in massive displacement, leaving families homeless or without access to basic necessities. We should move now to provide shelter and support to those affected. 3. Humanitarian organizations are working tirelessly in Yemen to deliver life-saving aid and provide healthcare to those in need. Your support can make a difference. Donate today and help save lives. 4. The healthcare system is on the brink of collapse. We must ensure that all Yemenis have access to medical services, especially women and children who are particularly at risk. 5. Children in Yemen are suffering the most from the ongoing crisis. They are facing malnutrition, lack of education, and the shocking impact of war. We should prioritize their well-being and invest in their future. 6. The agriculture sector has been extremely impacted due to the conflict, resulting in food insecurity. Supporting farmers and activating agriculture are crucial to achieving long-term food sustainability. 7. Access to clean water is a fundamental human right. In Yemen, millions of people lack safe water sources, resulting in the prevalence of disease. We must work together to provide clean water and health facilities.

Even if it's suffering time, The summer night is kind to me. The curtain swayed by the gentle breeze. I'm always good because I can talk to nature.

"Gray time" means, when you have such a good time that your mind is blown, creating a hazy. A little note: Gray is more common in the United States, and grey is more common in the rest of the English-speaking world.

Konnichiwa, Nao-san! Wow, those lyrics sound so familiar!! Aren't they from "I Want it That Way" by The Backstreet Boys? (They were one of my favorite musicians!) :)
