参考答案
参考解析
解析：空格后是一种装置，用它来改变火灾时找不到出口的危险境况。表达“用……装置”这层意思就要用介词with。其他几项均不符合句子的意思。
Sound Alert是一家公司的名字，a company是Sound Alert的同位语，根据句意判断，应选择run by，意为“由……经营的”。其他选项虽然语法正确，但都与句意不符。
从文章标题以及文章内容和本句后面部分resource center for the blind，可以推断这里最好的选择就是C。
因为这种警告装置已在上文中提到：第一段中的directional sound alarms，第二段中的installing the alarms in a residential home...，所以这里的alarms是特指，要用定冠词。选项C是错误的，因为它是单数形式。
句子的前半句有a wide range of frequencies，发出来的应该是sound，而不是令人烦躁的noise。用music或bell都有些突然，与上下文的意思不连贯。
文章一直在讨论警报器、声音和波长，所以首先排除选项A；从上下文的意思看，不可能是选项B和C，因为警报器的制造，就是为了让失明的人听到。
选择A、B、D均不能构成语义连贯的句子，而且语法上也有问题。选项C能使句子结构成为“It is... that”的强调句型。
从所给的选项可以看出，这里要表达的意思是“烟火弥漫的房间”。有了这个理解，现在要做的就是选择正确的表达形式。A是“烟熏的”,D是“使……烟火弥漫的”，所以意思不对，C填入后就出现filled with smoke room，不符合语法。只有B是正确选项。
这里显然是“It takes somebody + time +动词不定式”的句型，但选择什么时态是关键。从上句看，应选择一般过去时，因为整个段落是对一次实验的描写，而且上面一句也使用了一般过去时。
后半句的one指上半句中的a sound alarm。该句上半句和下半句由but连接，表示 相反的意思，从后半句的with可以看出，两个相对比的事物是：the door without a sound alarm和the door with a sound alarm，所以选择C。
选项B、C和D显然是错误的，因为词义不符。只有选项A是答案。句子的意思是，Withington在她的大学里研究大脑如何处理声音。
句子中的more...than表示该句是对两样事物的对比。than后面是the source of a narrow band，这里的narrow和前半句的wide形成反比，从上下文中可以看出，the source of a narrow band of ( frequencies）是和the source of a wide band of frequencies形成对比。
这个句子有主语alarms，有谓语have been installed，这里应填入动词的分词形式。 be based on是常用的搭配，所以应选择动词的过去分词形式。选项A. basis是名词，明显是错的。
根据上半句中的rising or frequencies，这里应填入or，与上半句表达的意思相一致。音频升高表示上楼，音频降低表示下楼。
首先确定主语They指的是第一句中的主语The alarms，后半句说这种设备得到大 笔资助。根据上文内容，我们知道资助的目的是开发这种alarms,所以应该选择devel- oped。
Sound Alert是一家公司的名字，a company是Sound Alert的同位语，根据句意判断，应选择run by，意为“由……经营的”。其他选项虽然语法正确，但都与句意不符。
从文章标题以及文章内容和本句后面部分resource center for the blind，可以推断这里最好的选择就是C。

What should you think about in trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. Knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metal work or cookery and look for a job where you can improve these skills.
If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in apart-time job. Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is bitter to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.
The writer thinks that for a student to have a part-time job is probably__________.

A．a waste of time that could have been spent on study

第三篇Look After Your VoiceOften speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in you mouth.First gently bite the edges of your tongue with your teeth.Or press your entire tongue to the bottom of your mouth and hold it there until the saliva flow.Or you can imagine that you are slicing a big juicy lemon and sucking the juice.Before you begin your talk,be kind to your voice.Avoid milk or creamy drinks which coat your throat.Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.If you sense that your are losing your voice,stop talking completely.Save your voice for your speech. You may feel foolish using paper to write notes,but the best thing you can do is to rest your voice.If you need to see a doctor,perhaps you can get some advice from a professional singer. In the meantime,do not even talk in a low voice.What about drinking alcohol to wet your throat?I advice you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence.The second drink gives you even more confidence.Finally you will feel all-powerful and you will feel you can do everything,but in fact your brain and your mouth do not work together properly.Save the alcohol until after you finish speaking.Perhaps you want to accept the advice,but you may wonder if you can ever change the habits of a life- time.Of course you can.Goethe,who lived before indoor skating rinks or swimming pools,said,"We learn to skate in the summer and swim in the winter."Take this message to heart and give yourself time to develop your new habits.If you are willing to change,you will soon be able to say that you will never forget these techniques because they became a part of your body.What did Goethe say about skating and swimming?A:He said people could learn to skate when it was hot and swim when it was cold.B:He said people could learn to skate and swim when it was hot.C:He said people could learn to skate and swim when it was cold.D:He said people could learn to skate when it was cold and swim when it was hot.

问答题Practice 1 No one knows what time itself is. We cannot see it. We cannot touch it. We cannot hear it. We know it only by the way we mark its passing. For all our success in measuring the tiniest parts of time, time remains one of the great mysteries of the universe. One way of thinking about time is to imagine a world without time. There could be no movement, because time and movement cannot be separated. A world without time could exist only as long as there were no changes. For time and change are linked. When something changes, you know time has passed.
