Iron is essential for human life,as it is a key part of various proteins and enzymes,involved in the transport of oxygen and the regulation of cell growth and differentiation,among many other uses.One of the most important roles of iron is to provide hemoglobin (the protein in red blood cells),a mechanism through which it can bind to oxygen and carry it throughout your tissues,as without proper oxygenation,your cells quickly start dying.If you have too little iron,you may experience fatigue,decreased immunity or iron-deficiency anemia,which can be serious if left untreated

英语作文140字Suppose a foreign friend of yours is coming to visit your campus , what is the most interesting place you would like to take him/her to see and why? 假设你的一位外国朋友来参观你的校园，你最感兴趣的地方想带他/她去看?为什么? 【参考范文】If I’m the guide of my foreign friend’s visit to our campus, I will choose the Cherry Avenue as our first destination. As the name implies, the Cherry Avenue is lined with hundreds of neatly-placed cherry blossom trees. It is about 200 meters long and a major scenic spot in our campus. In spring when the cherry trees bloom, the flowers are so dense that looking from a distance, it seems as if the road were surrounded by pinkhued clouds. Especially when there is a breeze, petals of cherry blossoms flutter and fall gently like a drizzle. Such breath-taking scene will put visitors into a kind of trance. What’s more special is the buildings along the avenue. Built in early 1900s, they are called "cherry blossom castle". They’ve witnessed the history of our school and even our country. You can learn a lot about our school there. In a word, a tour to the Cherry Avenue is both an amazing sightseeing and a great opportunity to know about the culture of our school.
