I’m sure many of you have seen Star Wars, Jurassic Park, Multiplicity, or many of the other movies that describe cloning. Most of what you see in these movies is false. What you don’t know is that cloning could be dangerous, to the clone and to our society as a whole. I think human cloning is wrong mainly for four reasons.
What about identity? Humans are promised the right to their own personalities. What would happen if we ignore those rights by giving them someone else’s genetic identity? True, Cloning may prevent people from possessing their identities.
Also, these is a large power struggle here. Cloning means a degree of power and controls over another person’s physical identity and that ignores their rights and their only personalities. The person doing the cloning would have more power than any parent would have.
Cloning would also deal with killing embryos (胚胎). You might not have known, but Dolly, the sheep that was cloned in 1996, was one of over 200 sheep embryos and hers was the only embryo that survived. The rest died or were thrown away. Imagine if the failure rate was that high when we started to clone humans. cloning means running the risk of wasting too much effort
Cloning someone, at this present time, would be extremely dangerous to the birth mother and the clone. In studies done on cows, 4 out of 12 birth mothers died. There is a very high failure rate, which is shown in the cloning of Dolly. Even if you had a few good embryos, failures have been noticeable in animal tests.
So, should we work ahead in the world of cloning? I say no. the risks are greater than the benefits. It’s dangerous to the clone and to the birth mother. We would be killing human lives in the process. It would also be a violation(侵害) of the clone’s right to its own genetic identity and personality.The author thinks human cloning is wrong mainly for ______ reasons.

Many children first learn the value of money by receiving an allowance (pocket money). The purpose is to let children learn from experiences at an age when financial mistakes are not very costly.
The amount of money that parents give to their children to spend as they wish differs from family to family. Timing is another consideration. Some children get a weekly allowance. Others get a monthly allowance.
In any case, parents should make clear what, if anything, the child is expected to pay for with the money. At first, young children may spend all of their allowance soon after they receive it. If they do this,they will learn the hard way that spending must be done within a budget (预算). Parents are usually advised not to offer more money until the next allowance. The object is to show young people that a budget demands a choice between spending and saving. Older children may be responsible enough to save money for larger costs, like clothing or electronics.
Many people who have written on the subject of allowances say it is not a good idea to pay your child for work around the home. These jobs are a normal part of family life. Paying children to do extra work around the house, however, can be useful. It can even provide an understanding of how a business works.
Allowances give children a chance to experience the three things they can do with money. They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want. Or they can save it.
Saving helps children understand that costly goals require sacrifice. You have to cut costs and plan for the future. Requiring children to save part of their allowances can also open the door to future saving and investing. Many banks offer services to help children and teenagers learn about personal finance. A saving account is an excellent way to learn about the power of compound interest.
Compounding works by paying interest. So, for example, one dollar invested at two percent interest for two years will earn two cents in the first year. The second year, the money will earn two percent of one dollar and two cents, and so on. That may not seem like a lot, but over time it adds up. Parents give their children allowances in order to _____.
| A．show off their wealth of family |
| B．let them make more money |
| C．learn the value of money |
| D．help children manage family finance |

| B．The way to spend alloweances. |
| C．the amount of allowances given to children. |
| D．Considerations taken to give allowances. |
Why are parents adivsed to offer young children allowances strictly as planned?
| A．To help children learn to make a budget. |
| B．To have children save money for larger costs. |
| C．To let children make fewer mistakes. |
| D．To give them more allowances next time. |
What does the author intend to tel lthe readers?
| A．The methods of limiting allowances. |
| B．The advice on a better family budget. |
| C．Teaching children to use allowances wisely. |
| D．Offering allowances to children properly. |
The adderis the only poisonous snake nativeto Britain. Adders have the most highly developed poison injecting mechanism of all snakes, but they are not aggressive animals. Adders will only use their poison as a last means of defence, usually if caught or trodden on. No one has died from adder bites in Britain for over 20 years. By far the most common smake in Britain is the adder. In Scotland, in fact, there are no other snakes at all. The adder is also the only British sanke with a poisonous bite. It can be found almost anywhere, but prefers sunny hillsides and rough open country, including high gournd. In Ireland there are no snakes at all.
Most people regard snake bites as a fatal misfortune, but not all bites are serious, and very few are fatal . Sometimes attempts at emergency treatment turn out to be more dangerous than the bite itself, with amateurs heroically, but mistakenly, trying do-it-yourself surgery and other unnecessary measures.
All snakes have small teeth, so it follows tha tall snakes can bite, but only te bite of the adder presents any danger. British snakes are shy animals and are far more frightened of you than you could possibly be of them. The adder will attack only if it feels threatened, as can happen if you take it by surprise and step on it accidentally, or if you try to catch it or pick it up, which it dislikes intensely. If it hears you coming, it will normally get out of the way as quickly as it can, but adders cannot move very rapidly and may attack before moving if you are very close.
The effect of a bite varies considerably. It depends upon severa things, one of which is the boidy-wight of the person bitten. The bigger the person, the less harmful the bite is likely to be, which is why children suffer far more seriously from snake bites in Britain ,and thought these bites can make some pepe very ill, there are probably just as many cases of bites having little or no effect, as there are of serious illness.What does the underlined phrase “ trodden on” probably mean?
| A．Found out | B．Heard from | C．Stepped on. | D．Robbed of. |
Where are adders to be found?
| A．In fertile fields in Scotland. |
| B．On wild land throughout Britain. |
| C．In many parts of Britain and Ireland. |
| D．Everywhere in Britian except Scotland |
What should you do if you are with someone who is bitten by an adder?
| A．Catch the biting adder at onece. |
| B．Don’t worry about the bitten person. |
| C．Don’t try to treat the bite by yourself. |
| D．Operate on the person as soon as possible. |

The greatest recent social changes have been in the lives of women. During the twentieth century there has been a remarkable shortening of the proportion of a woman's life spent in caring for the children. A woman marrying at the end of the nineteenth century would probably have been in her middle twenties ,and would be likely to have seven or eight children, four or five of whom lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which health made it unusual for her to get paid work.. Today women marry younger and have fewer children. Usually a woman's youngest child will be fifteen when she is forty-five years and can be expected to live another thirty-five years and is likely to take paid work until retirement at sixty. Even while she has to take care of children, her work is lightened by moder living conditions.
This important change in women's life-patterns has only recently begun to have its full effect on women's economic position. Even a few years ago most girls took a full-time job after they left school.. However, when they married, they usually left work at once and never returned to it. Today the school- leaving age is sixteen, many girls stay at school after that age, and though women usually marry older, more married women stay at work at least until shortly before their first child is born. Many more afterwards return to full-or-part-time work. Such changes have led to a new relationship in marriage, with the husband accepting a greater share of the duties and satisfactions of family life, and with both husband and wife sharing more equally in providing the money, and running the home, according to the abilities and interests of each of them.At what age did most women marry around the 1890 according to the passage?
| A．At about twenty-five | B．In their earl fifties |
| C．At the age of fifteen | D．At any age from fifteen to forty-five |

| A．was usaully expected to die fiarely soon |
| B．would expect to work until she died |

| A．Husbands and wives share equal responsibilities at home. |
| B．More and more women are looked down upon by husbands. |
| C．Today women prefer to get married rather than get jobs. |

My sister Jodie and I are always traveling for work. As jewelry designers, we need to go to a lot of shows. We can’t pack lightly and usually bring about four suitcases filled with our work.
Most of our stuff is made from heavy materials and metals. So part of the routine for us when we fly is getting stopped by security. Our jewelry sets off the alarms, and we’ve become accustomed to arriving early to go through private screenings. Most of the time, it’s not troublesome.
However, on our recent trip to a Paris trade show, we were stopped at security and asked to empty our bags. One of the agents walked over to another agent and they started whispering to each other. Both gentlemen came back, and one of them then told us that it seemed that we were carrying a very dangerous object.
My sister and I just said, “Huh?” Of course, we were a little concerned, thinking that maybe someone put something dangerous in one of our bags when we weren’t looking.
One of the agents then started to unpack our bags. I kept asking what he was looking for and then the object in question finally appeared. It was our Cosima necklace. It’s a piece of jewelry, with large, metal triangular spikes.
My sister and I looked at each other and breathed a huge sigh of relief. We started laughing and explained to the two male agents that it was just a necklace from our collection, not a weapon of mass destruction. They thought we were lying, and one agent kept repeating that he believed it was a weapon.
I tried to explain that we were jewelry designers going to a trade show, and this was simply a piece from our collection. But the agents didn’t buy it. Then a few women guards came over to assist. One of the women guards was holding an earring up to her ear and another was trying on a ring. Apparently, they liked our stuff.
It was only at this point that the male guards gave up. And I think they also got tired of listening to a bunch of women talk about jewelry. They let us through.
We took the names of the women agents and sent them a piece of jewelry when we got back to say thanks. When the object in question finally appeared, the writer and her sister felt _______.
| A．anxious | B．relieved | C．excited | D．frightened |
The writer and her sister were stopped by the agents because ________.
| A．their suitcases were too heavy |
| B．the agents wanted to play a joke on them |

The underlined word “buy” in Paragraph 7 probably means ________.
| A．doubt | B．believe | C．purchase | D．understand |
The writer sent the women agents a piece of jewelry in order to ________.
| A．persuade them to buy her jewelry later |
| B．get help from them next time |
| C．show them her talent in designing jewelry |
| D．show them her gratitude for their assistance |
