单选题德国人弗里茨?哈伯（Fritz Haber）由于发明了合成氨的方法而获

Most recently, it's very common in students who need a parent present for job interviews. Naturally, it's easy to blame the students in these situations, but the bigger problem is us. We—as parents—are so eager to shelter our kids that we fail to realize that this in itself is harming them. As the mother of two young sons, I have to remind myself constantly that the biggest responsibility I have as a parent is to help them develop the skills needed to live in, to live without me. So, I'll let them fail．
I'll let them fail because as long as they are safe and warm inside their comfort zones, they will never grow. And failure along with loss, heartbreak, disappointment, etc.—will be part of growth for them. Call me the anti-tiger mom, but leaving them alone is, my way of helping them become equipped to fit in this world as we know it today. From terrorism and seemingly endless natural disasters, to our national debt and beyond, if we expect the next generation to stand up to the very real problems of our time, we need to stop feeding them and start teaching them how to fish.
My children now are becoming little masters of compromise, but they try to negotiate everything now. It's a small price to help them learn a skill they'll use for the rest of their lives, including when I don't accompany them on job interviews.
【小题1】Why do parents accompany their kids on job interviews?A．Because they want to protect their kids from difficulties．B．Because they think they can help them on the questions．C．Because their kids are too shy to attend interviews．D．Because their kids strongly request them to do so．【小题2】According to the author, what is beneficial to kids' development?A．Sheltering them．B．Keeping them safe．C．Leaving them alone．D．Blaming them．【小题3】Why does the author stress failure in kids' life?A．To make them stronger than other kids．B．To help them grow in this tough world．C．To help them develop all social skills．D．To make them learn to compromise．【小题4】Which of the following might be the best title for the text?A．Never Shelter Your KidsB．Let Your Kids FailC．Be Eager to Grow UpD．Live Without ParentsA

D解析氮气和氢气合成氨气需要高温高压和催化剂，N的非金属性强于P的，所以氨气的稳定性强于磷化氢的。氨水中主要含有的是氨气分子，只有少量氨气和水反应生成了一水合氨。氨气制取硝酸铵，首先是氨气被氧化生成NO，NO再转化为硝酸。硝酸和氨气化合即生成硝酸铵，所以选项D是正确的。
