To Whom It May Concern,
I am a student in this university who regularly comes to the library to spend my spare time. Generally speaking, the services you offer here is quite good; however, I have some suggestions for you to adopt.
To begin with, will you please prolong the time for reading? In the daytime, most of the students are having class, so they can’t come to the library. Moreover, some of the books on shelves are out of date. If you are so kind as to provide us some books such as the latest magazines, we will be greatly honored.
I really wish to have a more comfortable library. I would like to extend my greatest appreciation if you are so kind to take my suggestions into consideration. /Thank you for your time and consideration.
Sincerely yours,
Li Ming
关于科技的英语作文四级预测【四】
人类能否穿越时空？主人公：小小葱探讨主题：人类能否穿越时空？观点：人类不可能穿越时空
小小葱想要穿越时空，于是……
众所周知，光速是每秒三十万千米，只有超越这个速度才可能穿越。我们可能不理解这是一个什么概念，我们假设一辆小汽车的速度为30千米/时。如果它们在一条三十万千米的赛道上竞速。光速只需一秒，而小汽车则需10000小时。所以我们超越光速非常困难。
就算我们可以超过光速，小小葱能够穿越。那么在未来的时空里便会有两个小小葱，穿越过去的小小葱如果是能量的存在就一定会对未来造成影响。有人说，那就让小小葱自。但是那也是行不通的。①如果小小葱自，那么他的穿越便没有了任何意义。②即使他了，也会对未来造成影响。科学家证实人后体重会减少21.3千克，灵魂的质量就是21.3千克，在未来时空会多出21.3千克的灵魂。并且尸体如果暴露在空气里会对空气造成影响。如果埋在土地里就会对土地造成影响。如果投入池塘便会对池塘里的水造成影响。
即使他造成的改变很小也会改变那个世界，就是涟漪效应。把一块石子投入池塘，水面就会泛起层层涟漪，即便放上极轻极轻的泡沫，那么涟漪也会出现，就会对水面造成影响。小小葱也是会对未来时空造成影响的。如果按小小葱没有穿越的正常时空行走，出现的时空便不是小小葱创造的未来。那么小小葱穿越后，正常的行走路线就会消失，以前的时空就是错误的存在，那么，那个时空将会消失，如果那个时空消失，小小葱就不会穿越，并且没有现在，就没有未来，未来时空便会消失。也就是每个时间出现的时空将不复存在。
按这样的.推理，自从小小葱穿越的那一刻起，宇宙就会消失，从而创造另一个宇宙，这种穿越，如果实现的话，也就是说会发生，而在这件事以后，还是有时间行走的，那么这也只是必然而已。并不是穿越。
由此得出结论：人类的科技再发达也不可能穿越时空，只是改变时空而已。
