As I understand, if scientists produced a human clone, there would be a great risk of it having a disease. Nobody seems to understand the ageing process of a clone. It would be terrible if a baby was the age of its parent at     31   . Its cells would grow old fast and it would die young.    32    until the technique is perfectly safe, it should be     33   .

I'd love to have a clone of     34   . I often wish I had a twin sister, someone who    35   me in everything. So why not a clone? Well, the idea    36   be fun but I'm not sure if it would be     37   . I think we would be playing with fire if we let scientists go ahead with     38   cloning. There are so many     39   

involved that all research in this area should be strictly controlled.

There are so many arguments     40    cloning that it is difficult to get anyone to consider the possible benefits. I am     41    that it is a technique which could be beneficial. The most obvious use would be for childless     42   . They would be able to have babies with their own genetic material. I don't see what's wrong with that.

Imagine a child     43    up knowing that his or her mother is really a sister or a brother. The emotional     44    on the child would be     45   . Or a child who was cloned from a dead brother or sister. What kind of emotional pressure would they feel, knowing they were made as a replacement for another? The whole idea

    46    me!

It's all very good to ban human cloning but scientists should be allowed to   47   

research. If they don't, we may     48    important benefits for our society, such as producing body organs. A clone is an     49    copy of a person with the same gene. Therefore, it is the     50    donor for an organ(器官) transplant.

【解析】文章講述的是關(guān)于人類克隆的話題,講述了人類克隆可能會(huì)出現(xiàn)的問(wèn)題和可能對(duì)人類社會(huì)帶來(lái)的益處。

1.句意理解,如果一個(gè)嬰兒剛出生就跟他的父母同齡,這將會(huì)是很恐怖的事情。

2.句意理解,這個(gè)嬰兒的細(xì)胞很快地衰老,并且很早就會(huì)死掉,因此,直到這個(gè)技術(shù)完全安全了,它將會(huì)被禁止使用。

3.同上

4.上下文,根據(jù)后面的I often wish I had a twin sister可知,作者想要克隆她自己。因?yàn)樗恢毕胗袀(gè)雙胞胎姐妹

5.上下文,根據(jù)上文可知,作者想要有一個(gè)雙胞胎姐妹,跟自己一樣,即resemble,意為,相像

6.情態(tài)動(dòng)詞,這個(gè)想法可能很有趣,但是我不確定這是否安全。May 可能 ,must 必須 can 可能(理論上的可能),shall將要

7.同上,在第32空也有體現(xiàn)

8.上下文,作者此處講的是克隆自己,所以是人類的克隆

9.上下文,根據(jù)后面的all research in this area should be strictly controlled可知,克隆是因?yàn)榇嬖诤芏囡L(fēng)險(xiǎn),所以要被嚴(yán)格地控制

10.上下文,根據(jù)后文的 it is difficult to get anyone to consider the possible benefits可知,這是反對(duì)克隆的觀點(diǎn),所以選擇argue against即反對(duì)

11.上下文,后面的 it is a technique which could be beneficial是作者個(gè)人的觀點(diǎn),所以要選擇B,意為我深信,這個(gè)技術(shù)是可以對(duì)人類有益的。

12.上下文,根據(jù)childless可知,此處指的是沒(méi)有孩子的夫妻可以克隆一個(gè)自己的孩子。

13.句意理解,此處意為,當(dāng)一個(gè)孩子長(zhǎng)大后發(fā)現(xiàn)他的父母是他的兄弟姐妹的話,他精神上的壓力將會(huì)是無(wú)法承受的

14.上下文,根據(jù)后面的What kind of emotional pressure would they feel可知

15.同43

16.句意理解,這種想法讓我自己都嚇到了。

17.上下文,根據(jù)后面的If they don't, we may     48    important benefits for our society可知,作者支持科學(xué)家繼續(xù)研究克隆

18.句意理解,如果不繼續(xù)研究的話,我們可能會(huì)錯(cuò)過(guò)很多對(duì)社會(huì)有益的東西,

19.克隆是對(duì)一個(gè)人的完全相同的基因復(fù)制,因此這是器官移植的理想捐贈(zèng)方式 identical意為完全一樣的

20.ideal意為理想的

I hadn’t really planned on taking a trip this time of year, and yet I found myself packing rather hurriedly. I knew in   36   that this trip was going to be unpleasant.
I’m talking about my annual Guilt Trip. I got tickers to fly there on WISH – I – HAD’ airlines. I   37   my baggage all the way, which was weighted down with a thousand   38   of ‘what might have been’. No one greeted me at the ‘Regret City’ International Airport.
As I   39   into the Last Resort Hotel, I noticed to miss that great   41   occasion.
Many leading citizens went there. First, there was the ‘Should – Have - Done’ family.   42   came the ‘I – Wish’ family. Of course, the ‘Opportunities’ family, ‘Missed and Lost’, surely made an   43  . They each had a dad story to share. ‘It’s – Their - Fault’ treated us with stories about   44  things had failed in his life, and each story was applauded by ‘Don’t – Blame - Me’ and ‘I – Couldn’t – Help – It.’
To make a long   45   short, I became very depressed at the party   46  .
But as I though about all the stories of failures   47  from the past, it occurred to me that all of this trip and ‘pity party’ could have been cancelled by ME!
I truly realized that I didn’t have to be there to be   48  . One thing kept going through my mind – I can’t change yesterday, but I   49   have the power to make today a wonderful day. Knowing this, I left ‘Regret City’ immediately. Am I sorry for   50  I’ve made in the past? YES! But there is no physical way to undo them.
So, if you’re planning a trip to ‘Regret City’, please cancel all your reservations now.   51  , take a trip to a placed called ‘Starting Again’, which I like so much that I’ve made it my   52   residence. My neighbors, the ‘I – Forgive - Myselfs’ and the ‘New - Starts’ are so very helpful.
By the way, you don’t have to carry   53   heavy baggage, because the load is lifted from your shoulders   54   arrival. Surely you’ll find this great town – it’s in your own heart. Look me up if you’re ready for a (n)   55   changer in your life. I live on ‘I – CAN – DO – IT ’ Street.

That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theatre. With opening night only a week away, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me.
As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away from any possible robbers (搶劫犯). Very few people were still out except a few sad-looking homeless people under blankets.
About a block from my apartment (公寓房間), I heard a sound behind me. I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk.
Suddenly I wasn’t cold or tired anymore. I ran out of the door and back to where I’d heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.
Just as I was about to give up the search, I heard the garbage truck (垃圾車) pull up to the sidewalk next to me. When a voice called from the inside, “ Alisa Camacho?” I thought I was dreaming. How could this man know my name? the door opened, and out jumped a small red-haired man with an amused look in his eyes. “Is this what you’re looking for?” he asked, holding up a small square shape.
It was nearly 3 A.M. by the time I got into bed. I wouldn’t get much sleep that night, but I had gotten my wallet back. I also had gotten back some enjoyment of city life. I realized that the city couldn’t be a bad place as long as people were willing to help each other.
1. How did the writer feel when she was walking home after work?
A. Cold and sick           B. Fortunate and helpful
C. Satisfied and cheerful      D. Disappointed and helpless
2. From the first paragraph, we learn that the writer was busy ______.
A. solving her problem at the bank         B. taking part in various city activities
C. learning acting in a n evening school      D. preparing for the first night show
3. On her way home the writer _______.
A. lost her wallet unknowingly               B. was stopped by a garbage truck driver
C. was robbed of her wallet by an armed man   D. found some homeless people following her
4. In the fifth paragraph, why did the writer say she was dreaming?
A. Someone offered to take her back home. B. A red-haired man came to see her.
C. She heard someone call her name D. Her wallet was found in a garbage truck.
5. From the text, we can infer that the writer _________.
A. would stop working at night       B. would stay on in San Francisco
C. would make friends with cleaners    D. would give up her job at the bank
