Article: You may never connect the words "good" and "eco-friendly"with plastic.It's time to do a rethink on that as we say hello to hemp plastic.Traditionally,plastics have been made from petrochemicals,which are mainly poisonous.Plants,on the other hand,are also a source of cellulose ,which can be used to make biodegradable plastic.As hemp happens to be one of the richest sources of cellulose,it is only natural that scientists will support its use,considering its ecological benefits. Hemp plastic is biodegradable and recyclable.If you thought being eco-friendly reduced its solidity,you couldn't be more wrong.The hard level of hemp plastic can match that of regular plastic.Hemp plastic is resistant to heat;however,the most outstanding feature of a few varieties of hemp plastic is that they are flame resistant too.Finally,if Henry Ford could imagine creating a car with this material,we can perhaps believe that it indeed is"ten times stronger than steel". It is a pity that with so many useful qualities,we don't see hemp plastic being used in our everyday life,the way it ought to be.Hemp plastic can easily take the place of the exiting plastic in products like cell phone chargers ,laptop covers,etc.Currently,hemp plastic is being used to produce audio ,video,toys,automobile parts and packaging materials. Hemp fiber is one of the strongest natural fibers known to us.As scientists keep looking for ways to solve the ecological damage that traditional plastics have caused,here is a material that can be produced to be 100% biodegradable.Hemp plastic is known to be several times _ as compared to polypropylene plastic,and it comes without all the health and safety threats,It really has long useful life. Plastics keep reminding us of the damage that we have done to our planet,all under the excuse of convenience.As hemp products have become a new choice into our daily life,Please take a green plan now and make your effort to protect the environment. Question: What can we know from the passage? Options: A: Using hemp plastic is inconvenient. B: People haven't made the most of hemp. C: Hemp fiber is a kind of strong man-made fiber. D: Scientists have already known how to solve ecological damage.

Read the article and select the best answer. Article: For many centuries,countless scholars have asked the question:What is beauty? As designers update the latest fashions and artists create their masterpieces, what is considered beautiful changes at an alarming pace. Fifty years ago,the full-figured Marilyn Monroe was a symbol of the American aesthetic value;today,many Hollywood actresses different in appearance from Marilyn's have taken her place. However,aesthetic values not only differ from generation to generation,but do so along cultural lines as well. Often, what is considered disgusting to one civilization is just the aesthetic appeal in another. Thus it is difficult to give an absolute definition of beauty. As fundamental physicists,my colleagues and I like to believe that we are involved in a search for a beauty that affects definition. The beauty that we search for is not what is set up through the work of people and subject to the tastes, but rather what has been laid down by nature Physics allows its students to look past outer appearances,into a deeper beauty. As a human being,I am attracted by the visual appeal of a wave crashing on the beach. As a physicist, however I am able to see the deeper beauty of the physical laws that govern such a phenomenon. In truth,since Albert Einstein put forward the idea that there might be one main physical theory that governs the universe,aesthetics have become a driving force in modern physics. Einstein and other later physicists have discovered that:Nature, as its most fundamental level,is beautifully constructed. The extraordinary simplicity of the laws that govern the universe is really breathtaking . As Einstein said, it would seem more likely that we should find ourselves living in a"chaotic world,in no way graspable through thinking". Yet we are now closer than ever to a full understanding of the universe's beautiful clockwork. As new discoveries and technologies allow us to examine the physical world on deeper and deeper levels,we find that the beauty itself becomes much deeper. Question: When appreciating a wave crashing on the beach,a physicist sees the beauty of _ . Options: A: the visual attraction B: the powerful sounds C: the physical laws behind D: the lovely creatures

The girl was assigned to look after an old man suffering from cancer whose children lived abroad. Their living conditions were not satisfactory while the old man had a lot of savings.
