A．a；/B．the； theC．a； theD．/；/

分析 和人类比起来，动物明显是生命的低等形式．

解答 答案：A 题干中form形式，可数名词，表示一种形式，要用不定冠词来限定；man指人类时，是抽象名词，不加冠词．故选A．

点评 冠词是一种虚词，本身不能独立使用，只能放在名词前帮助说明名词所指的人或事物，它是英语词性中最小的一类，只有三个，一种是不定冠词a，an；一种是定冠词the．此外也有些特定场合不用冠词，即通常所称的零冠词．不定冠词表示泛指，定冠词表示特指．

19．If you could be anybody in the world，who would it be？Your neighbour or a super star？A few people have experienced what it might be like to step into the skin of another person，thanks to an unusual virtual reality（虚拟现实）device．Rikke Wahl，an actress，model and artist，was one of the participants in a body swapping experiment at the Be Another lab，a project developed by a group of artists based in Barcelona．She swapped with her partner，an actor，using a machine called The Machine to Be Another and temporarily became a man．"As I looked down，I saw my whole body as a man，dressed in my partner's pants，"she said．"That's the picture I remember best．"
  The set-up is relatively simple．Both users wear a virtual reality headset with a camera on the top．The video from each camera is sent to the other person，so what you see is the exact view of your partner．If she moves her arm，you see it．If you move your arm，she sees it．
  To get used to seeing another person's body without actually having control of it，participants start by raising their arms and legs very slowly，so that the other can follow along．Eventually，this kind of slow synchronised（同步的）movement becomes comfortable，and participants really start to feel as though they are living in another person's body．
  Using such technology promises to alter people's behaviour afterwards-potentially for the better．Studies have shown that virtual reality can be effective in fighting racism-the bias（偏见）that humans have against those who don't look or sound like them．Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test，which measures the strength of people's associations between，for instance，black people and adjectives such as good，bad，athletic or awkward．Then they asked them to control the body of a dark skinned digital character using virtual reality glasses，before taking the test again．This time，the participants'bias scores were lower．The idea is that once you've"put yourself in another's shoes"you're less likely to think ill of them，because your brain has internalised the feeling of being that person．
  The creators of The Machine to Be Another hope to achieve a similar result．"At the end of body swapping，people feel like holding each other in their arms，"says Arthur Pointeau，a programmer with the project．"It's a really nice way to have this kind of experience．I would really，really recommend it to everyone．"

20．At the age of 45 I decided to learn the English language．Not that I didn't know the language，but to improve my command over the language，I joined English academic classes close to my house．In one class，the instructor gave us a sheet of a hundred words and told us to write the opposite of each word as homework．At home I sat with that page but though I could manage the easy words quickly，for certain words I had to take the help of the dictionary．
Feeling relaxed and like an achiever，my new found enthusiasm forced me to explore some more words．Exploring the dictionary，for every word I found the opposite word （except all forms of nouns）．The entire night went on exploring words，but the night was not enough to complete the dictionary．I had enough time to hand in my homework，so the next day，after work once again I sat in through the night and started exploring opposite words from the dictionary．
The exercise was easy，but suddenly something struck my mind．Instead of finding the words which have opposite words，I should look for words that do NOT have any opposite word．After going through sleepless nights that week，I could not find a single word which doesn't have an opposite word．
This amazed me and forced me to conclude that without the opposite word the original word doesn't have its real meaning or value．In other words，every word is incomplete without its opposite．The conclusion forced me to think differently．Although many questions remained unanswered in my mind，the one thing I concluded was that these words are created by humans and every human possesses two qualities within himself，Positive and Negative．Similarly he created words with opposites．This proves that whatever we welcome in our life，we will also be welcoming the opposite of it．And at the end of the day we will complain about the negative forces surrounding us，making us weak，dull，pessimistic（悲观） and so on…Isn't this strange？
