答案

小题1:second
小题2:worst
小题3:impolite
小题4:herself
小题5:Hopefully

解析

试题分析：
小题1:句意：据报道：中国夫妇如果有一方是独生子女就可以生第二个孩子。此处要用序数词，故答案为second。
小题2:句意：我认为Jim不是比赛中的最后一名。三者及三者以上进行比较要用最高级，故答案为worst。
小题3:句意：他是一个不礼貌的男孩，没有人喜欢他。根据后半句nobody likes him可知此处应该填polite的反义词，故答案为impolite。
小题4:句意：Millie从不抄袭别人的作业，她一直是自己完成。by onself“依靠自己”，故答案为herself。
小题5:句意：我们都知道旅游景点的门票很贵。有望的是，南京不久后所有的名胜古迹都会向当地人免费开放。此处要用副词，故答案为Hopefully。

We are now living in the modern society. Most of the energy we use for heating, lighting, transportation and manufacturing (制造业) comes from fossil (化石) fuels. These are carbon-based fuels from oil, coal and natural gas. When we burn these fuels we release heat which p__小题1:___ the energy.
There are three main disadvantages to using these fuels. Firstly, they are causing climate problems because of the G_小题2:___ Effect. When we burn fossil fuels they produce carbon dioxide which causes global warming. Secondly, when we have used up all our coal, oil and natural gas, we will have n__小题3:__ left to burn. Thirdly, they are not very efficient. The internal combustion engine (内燃机) that we use in most cars, trucks and buses, for example, is only about 14% efficient.
Scientists are working on another fuel—hydrogen. There are a couple of advantages to using hydrogen as a fuel. Firstly, because two-thirds of the e__小题4:__ surface is water and water is made of hydrogen and oxygen. There is an almost unlimited supply of hydrogen. Secondly, burning hydrogen does not cause global warming. Thirdly, it is much more efficient than carbon-based fuels.
Unfortunately there are problems with hydrogen at the present time: there is the problem of separating (分离) it from water c_小题5:___, and there is the difficulty of storing it. It can be stored under pressure but high pressure tanks are far from safe. It can also be stored as a liquid but only at extremely low temperatures. It seems likely, therefore, that there will have to be a completely new technology before hydrogen replaces fossil fuels. S__小题6:___ these problems is an urgent (急迫的) matter. Although China, India and Australia have huge amounts of cheap coal, and there are still l__小题7:___ oil and gas reserves(储藏量) elsewhere, the effects on the planet’s climate will be bad if they are used.
