As if there weren’t enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic (治疗的) stem cells.
In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(细胞核) has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly ‘reprogrammed’.
Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos(晶胚) might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized(已受精的) fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics.
【小题1】The best title of this passage probably is _______.

A.The importance of clone
B.First insects are cloned
C.The disagreement in clone
D.The advantages of clone
【小题2】The scientists cloned flies because________.
A.there are fewer and fewer flies in the world
B.flies are easy to find and cheap to use
C.they can gain some experience before cloning other animals
D.it is safe to clone flies
【小题3】The failure of most cloned animals is due to _______.
A.the difference of other animals’ genes
B.the improper technique of clone
C.the complex of other animals
D.the improper rearrange of the adult gene
【小题4】It can be inferred from the last paragraph that ______.
A.the clone of insects before used grown-up cells
B.the clone of insects were never experimented before
C.this time scientists cloned flies successfully and easily
D.based on this success, other animals will be cloned in large quantities.

Welcome every morning with a smile. Let your first hour set the theme of success and positive action that is certain to echo through your entire day. Today will never happen again. Don’t waste it with a false start or no start at all. You were not born to fail.
Starting the day right can give good momentum (动力) for the rest of the day. Having a power morning is a key factor for a fruitful day. Here are some tips on getting the most out of the morning.
Wake up early. In theory, there’s no difference in waking up early or late as long as you get the proper amount of sleep. However, there is a psychological advantage when you wake up earlier than the average person and then you’ll have more time to do preparation before engaging in the real world.
Exercise. Good health is always a benefit with exercise, but studies have also shown that morning exercise helps you to sleep better at nights.
Eat breakfast. It’s the most important meal of the day. According to the Mayo Clinic, we should choose three from the following four: fruits and vegetables, grains, dairy, and protein. Did you know that you can actually gain weight when you skip breakfast?
Take a shower. When you shower, do you do it in the morning or at night? I used to shower in the evenings, but I found that morning showers helped me to be more alert.
Prioritize (优先) your To-Do list. Leo coined the acronym MIT to mean “most important tasks.” Our to-do list might be never ending, but put on top of the list a couple of urgent tasks that will define the day to be a successful one.
Check your emails. Only once. Getting a lot of emails can be very distractive. You actually are more productive when you check them only a few times at fixed time of the day. I only do them 2-3 times a day—once in the morning, once at lunch, and one more as it gets toward the end of the day.
【小题1】The purpose for the author to write this passage is to       .

A.tell you to get up early every day
B.offer you the best way to start the day
C.give you advice about how to arrange a day
D.advise you to prioritize your to-do list every morning
【小题2】If you don’t have breakfast, you may       .
A.lose weight.B.be productive.
C.put on weight.D.be more alert.
【小题3】The underlined word “coined” in Paragraph 6 means       .
A.inventedB.designedC.foundedD.defined
【小题4】The author advises you to check your emails only once because       .
A.the emails are not important
B.reading e-mails is distractive
C.you can only read e-mails at fixed time
D.getting so many emails can distract your attention

People in the UK often talk about their homes: their mortgages (按揭), the interest rates, and rising prices. Here’s a guide to some of the words and phrases you might come across.

It’s a good idea in the UK to arrange a mortgage with a bank before you start looking. This is when the bank tells you how much money they will lend you so you have a good idea of how much you can afford.

The next step is to go to an estate agent and see what sort of properties they have available in your budget range and in your area. If you see something you like, the estate agent will arrange for you to view the property, so that you can see the house or flat for yourself.

If you see something that takes your eye, you put in an offer. The vendor (卖家) can accept or decline this offer, and if the vendor accepts it, you can move forward with the sale. However, as you don’t pay any money at this point, the offer isn’t legally binding (具有约束力), and in theory, you can pull out of the offer at any time that you like.

Your next step will probably be to get a structural survey done. A qualified surveyor will inspect the house and write a report that illustrates any structural problems, like damp or drainage problems.

If you still want to go ahead with the sale, you need to appoint a lawyer to do the legal paperwork.. If you already own a house, you might also be busy trying to sell it. Many house owners prefer to sell to first-time buyers (those people who don’t already own a home), as they are not in a chain (waiting for other people to buy the house before they can buy their next house).

Finally, once the contracts are signed and exchanged, you complete on your house. You get the keys and you can move in whenever you want. Then you might want to throw a house-warming party. Congratulations!

1. Which of the following shows the right order of what happens before the people in the UK move into a new house?

a. ask for a company which represents others of properties

b. decide how much to borrow from the bank

c. examine the structure of the house

d. hire a lawyer and make a contract

e. offer the seller the right money

f. visit the house and discuss a price with the seller

A.b, a, f, d, c, e                           B.b, a, f, c, d, e

C.b, a, f, e, d, c                           D.b, f, d, e, c, a

2. According to the passage, these statements are correct EXCEPT ___________.

A.People can borrow the whole money for a new house from a bank.

B.People care for mortgages, interest rates and the prices &house.

C.The sellers are more interested in the first-time buyers.

D.After getting the keys, the owners sometimes have a party.

3.Which of the following is NOT mentioned in the passage?

A.Owners.                              B.Surveyors.

C.Lawyers.                              D.Collectors.

4. The passage is maybe one that _______________.

A.give some advice on the house

B.introduces a book on travelers

C.give some tips to buyers

D.introduces a guide to visitors

Have you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. That’s nothing more than a fiction.

But could we really clone endangered animals?

    To date, the most successful attempt to do so was the cloning of a gaur, a rare ox-like animal from southeast Asia. Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope (羚羊), the Sumatran tiger, the cheetah (猎豹), and the giant panda.

Next, could we really clone extinct animals?

In theory? Yes. To do this, you need a well-kept source of DNA from the extinct animals such as wool mammoth (毛象), Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate mother.

In reality? Probably not. On the one hand, it’s not likely that extinct animals’ DNA could survive undamaged for such a long time. Cloning such extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly well-preserved DNA. On the other hand, for example, a gaur can have a cow as a surrogate mother, definitely not a monkey. But what about an extinct animal as unique as the panda? What species could possibly serve as a surrogate mother?

   Cloning presents many exciting possibilities. However, even if extinct animals were brought back, they could not survive in today’s world. Not only do most extinct animals have no habitat to love in, but the other plants and animals they depended on for food may also be gone as well.

1. It can be learned from the text that ________.

A. the gaur is an extinct species

B. the gaur lives in Asia and is endangered

C. scientists have cloned the African bongo antelope

D. both the cheetah and the giant panda live in Asia

2.The underlined words “a surrogate mother” probably refer to a female who ______.

A. gives birth to a baby of its own                 B. cannot give birth to a baby

C. gives birth to a baby for another female             D. provides DNA

3.The difficulty in cloning an extinct species is the lack of ______.

A. both the well-preserved DNA and a surrogate mother

B. both the habitat to live in and the well-preserved DNA

C. both the well-preserved DNA and plants to live on

D. both the habitat to live in and plants to live on

4.In the author’s opinion, it is possible that ______.

A. all the extinct species may be cloned

B. extinct species may be cloned and easily survive

C. a gaur can have a monkey as a surrogate mother

D. some extinct species may be cloned, but not survive
