甲公司与乙公司签订一个供货合同,约定由乙公司在一个月内向甲公司提供一级精铝锭100吨,价值130万元,双方约定如果乙公司不能按期供货的,每逾期一天须向甲公司支付总货款的0.1%作为违约金。由于组织货源的原因,乙公司在两个月后才向甲公司交付了100吨精铝锭,甲公司验货时发现不是一级精铝锭,而是二级精铝锭,就以对方违约为由拒绝付款,要求乙公司支付退延一个月的违约金39000元,并且要求乙公司重新提供100吨一级精铝锭。但是乙公司称逾期供货不是自己的过错,而是国家的产业政策调整导致,不应该支付违约金,而且所提供的精铝锭是经过质量检验机构检验合格的产品,甲公司不应当小题大做,现在精铝锭供应比较紧张,根本不可能重新提供精铝锭。甲公司坚持以公司应当支付违约金和按照合同约定的质量标准履行合同。双方为此发生争议,甲公司起诉至法院,要求乙公司支付违约金和重新履行合同。乙公司在答辩状中称,逾期供货不是自己的本意,也不是自己所能控制得了的,不应当支付违约金,即使支付违约金,也不应当支付39000元之多,这个请求不公平。根据上述材料,回答下面问题:

若甲乙公司约定,乙公司负责货物的运输,则下列有关该批精铝锭的所有权和风险责任转移的说法正确的是( )。

A.若甲乙约定了交付地点,则货物的风险自乙公司将货物运至交付地点时转移给甲公司

B.若甲乙约定了交付地点,则货物的风险自乙公司将货物交给第一承运人时转移给甲公司

C.若甲乙未约定交付地点,则货物的所有权自乙公司将货物交给第一承运人时转移给甲公司

D.若甲乙约定了交付地点,货物运至甲公司后,甲公司不得要求乙公司就货物不符合约定承担违约责任

E.若甲乙约定了交付地点,但运至后甲公司发现货物不符合要求而拒绝受领,则货物毁损灭失的风险由乙公司承担

Picture a library without books? Well, I can’t. Ever since I was little I would go to the library and take out numerous books. From picture books to beginning chapter books to YA books, books have always been a part of my life. Unlike many people today, I don't own a Kindle or a Nook or any type of e-reader. I prefer the old-fashioned book. There is something about holding a book and being able to turn the pages that I find comforting. In today's 21st century, books may become obsolete. For me that's something I find scary.

I am a fan of the old TV science-fiction series Twilight Zone. One episode(一段情节)is about a librarian who has become obsolete. Though this episode aired in 1961, the writer of the series, Rod Serling was exactly on point when it came to predicting the future.

In fact, in San Antonio, Texas the first-ever bookless library in the country opened. The library is full of iMacs, tablets and iPads which cost a huge $2. 3 million. The library offers around 10,000 e-books. So the question is, is this what the future will soon be? Mary Graham, vice president of South Carolina's Charleston Metro Chamber of Commerce states, "This is the future…If you're going to be building new library facilities, this is what you need to be doing."

It is our generation that will be the guinea pigs(试验品)of increasing technology like this. Is this a good or bad thing? Well, digital libraries may help the environment by not using paper; however, I feel like something will always be lacking with a digital book. A digital library is just the beginning.

With all of this new technology, people seem to be more absorbed in their own world. One of my biggest complaints is when I am with my friends and they can't seem to get off their smart phone and talk to me. To make plans with a friend and then have them stuck on their phone the whole time is extremely rude. Not only is it disrespectful, but it reflects the direction of where human interactions are heading. Though social media is great, it also is addicting and has negative effects.

Often when I go on Facebook it just makes me feel worse about myself. I'll see many of my 800 Facebook friends showing off their newest accomplishment or acceptance to college. Additionally, our society is becoming increasingly lazy. For instance, instead of doing mental math, people use their phone to solve 89 + 74. It is simple tasks like these that are allowing people to lack important educational and social skills.

It is up to us to find a balance between technology and human values and interactions. With new technology being created every day, we need to learn how to use it alongside our great minds. After all, inventions are supposed to benefit society not harm it. In the day of technology, who knows what's next?
