9．Animals are obviously ________ lower form of life than ________ man．（　�。�
A．a；/B．the； theC．a； theD．/；/

分析 和人類比起來，動物明顯是生命的低等形式．

解答 答案：A 題干中form形式，可數(shù)名詞，表示一種形式，要用不定冠詞來限定；man指人類時，是抽象名詞，不加冠詞．故選A．

點評 冠詞是一種虛詞，本身不能獨立使用，只能放在名詞前幫助說明名詞所指的人或事物，它是英語詞性中最小的一類，只有三個，一種是不定冠詞a，an；一種是定冠詞the．此外也有些特定場合不用冠詞，即通常所稱的零冠詞．不定冠詞表示泛指，定冠詞表示特指．

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（虛擬現(xiàn)實）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（偏見）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．"

74．The word"swapping"（paragraph 1）is closest in meaning toB．
A．building        B．exchanging         C．controlling         D．transplanting
75．We can infer from the experiment at the Be Another lab thatA．
A．our feelings are related to our bodily experience
B．we can learn to take control of other people's bodies
C．participants will live more passionately after the experiment
D．The Machine to Be Another can help people change their sexes
76．In the Implicit Association Test，before the participants used virtual reality glasses to control a dark skinned digital character，D．
A．they fought strongly against racism
B．they scored lower on the test for racism
C．they changed their behaviour dramatically
D．they were more biased against those unlike them
77．It can be concluded from the passage thatC．
A．technology helps people realize their dreams
B．our biases could be eliminated through experiments
C．virtual reality helps promote understanding among people
D．our points of view about others need changing constantly．

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（悲觀） and so on…Isn't this strange？
29．The author finished his first homeworkC
A．a(chǎn)t the first attempt                  B．with great ease

A．The pressure of homework
B．The deep interest in word formation
C．A sense of achievement
D．The encouragement of instructors．
31．According to the author，C
A．not every word has its opposite word
B．every word has more than one meaning
C．it is the opposite that makes a word complete
D．every word has positive and negative meanings
32．Which of the following idioms may the author agree more with？A
