26、 As early as 2005, there were a number of new stories about dog cloning(克隆) and cat cloning. Animal cloning had been old news for nearly a decade by then, with the revolutionary (革命的) cloning of Dolly the sheep in Scotland.
However, Snuppy was the first pet, a dog, to be cloned. Since the cloning of Snuppy, there has been some very successful cloning of pets and other animals. Lou Hawthorne started BioArts while cloning his beloved mixed-breed dog Missy. Hawthorne was very pleased with the results of the cloning, producing three successful clones that were very alike to the original in character and behavior. In January, 2009, a Florida couple, Ed and Nina Otto, announced that they had paid to have their dog cloned by BioArts.
All new technology is overpriced. For example, personal computers were not very affordable at first. Only after the producing process was improved was it possible for every family to have a computer. How much room there will be for organizations to reduce the price point on pet cloning without broad demand is of course questionable.
There are many great dogs and cats that can be found at the local dog pound ( 野狗收容所) or are given away for “free to good homes” in classified ads (分类广告). However, there is no limit to the value people place on a beloved pet. The Ottos are a good example of that. If people can buy a dog or cat with predictable behavior and characteristics, there is value in that. There is a predictable market here, though it may always be limited in size.
While pet cloning has not taken off as some hoped, it’s clear that it will become a bigger market in the future and it will be increasingly possible for people to try this out. With the inevitable (不可避免的) success that cloned pet owners will have, the practice will become more widely accepted and it seems inevitable that there is a future for cloned dogs and cats.
【1】What is the main idea of this passage?
A. The brief introduction of pet cloning. B. The behavior of cloned animals.
C. The cases of pet cloning. D. The history of pet cloning.
【2】What can be inferred from the passage?
A. Pet cloning will be accepted by everyone.
B. New technology of pet cloning will be invented.
C. Human cloning may one day become a reality.
D. The price of pet cloning may not be cheap.
【3】Which of the following has the closest meaning to the underlined word in the third paragraph?
A. cheap B. wonderful
C. expensive D. various
【4】What does the author think of the market of pet cloning?
A. Negative B. Not clear
C. Indifferent D. Optimistic
27、 In many countries of the world, people can confidently tell you the meaning of their town or city, but most people who live in Manchester, Oxford or Birmingham would not be able to explain what the name of their city means. The name of every British town and city, however, has a long history.
Two thousand years ago, most people living in Britain were Celts. Even the word “Britain” is Celtic. Then the Romans arrived and built camps which became cities called “castra”. This is why there are so many place names in England which end in “-chester” or “-caster” – Manchester, for example.
The Romans never reached Wales or Scotland, and many place names there are Celtic (凯尔特语的). For example, Welsh place names that begin with “Llan” come from the Celtic word for church.
After the Romans left Britain, it was attacked by tribes (部落) called the Anglo-Saxons who were from the area of Europe that is now Germany and Holland. Without the Roman army, it was impossible to protect the country from these people. The names of their villages often ended in “-ham” or “-ton”. Some got their name from the leader of the village, so Birmingham, for example, means “Beormund’s village”.
The Anglo-Saxons were farmers and the landscape was very important to them, so we have villages called Upton (“village on a hill” – a good place to build a village) and Moreton (“village by a lake”, where floods could make life tough). Place names that end in “-ford” (a place where you could cross a river) also describe the location of Anglo-Saxon villages.
Twelve hundred years ago, the Vikings came to England from Scandinavia. They traded with the Anglo-Saxons but lived in their own villages. These often ended in “-by” or “-thorpe”. The name “Kirkby” means “a village with a church” and Scunthorpe was the village of a man called Skuma.
Finally, in 1066, England became Norman – the Normans gave us the place name “grange”, which means farm.
And how about London? Experts cannot agree. The Romans called the city Londinium, but they were not the first inhabitants (居民). People once believed that the United Kingdom’s capital city got its name from the castle (城堡) of a King called Lud, but this is very unlikely. Our best guess today is that the name comes from a Celtic word meaning a fastflowing river. Like a number of British place names, its history is lost in time.
【1】The origin of British place names is unfamiliar to many local people because of ______.
A.the death of ancient languages B.their lack of interest in the names
C.the long lost history of the names D.the frequent changes to the names
【2】According to the article, Stratford-upon-Avon is most likely a town built______.
A.beside a river B.near a castle
C.on a hill D.with a church
【3】Which of the following shows the correct order of the arrival of inhabitants in Britain?
A.The Celts — The Romans — The Vikings — The Normans — The Anglo Saxons
B.The Celts — The Romans — The Anglo Saxons — The Vikings — The Normans
C.The Romans — The Celts — The Vikings — The Anglo Saxons — The Normans
D.The Romans — The Anglo Saxons — The Celts — The Normans — The Vikings
【4】According to the text, where did the name for London come from?
A.It is short for Londinium. B.It’s from the term for a river.
C.It is puzzling and hard to confirm. D.It comes from the castle of a King.
28、In a study published in Nature Machine Intelligence, researchers at Ohio State University show how artificial intelligence（AI）can follow clinical trials to identify drugs for repurposing, a solution that can help advance innovative treatments.
Repurposing drugs is legal and not unusual. When doctors prescribe(开处方)drugs that have been approved by the Food and Drug Administration(FDA)for purposes different from what is printed on the labels, the drugs are being used “off-label” Just because a drug is FDA-approved for a specific type of disease does not prevent it from having possible benefits for other purposes.
For example, Metformin, a drug that is FDA-approved for treating type 2 diabetes, is also used to treat PCOS(a disease of women), and other diseases. Trazodone, an anti-depressant with FDA-approval to treat depression, is also prescribed by doctors to help treat patients with sleep issues.
The Ohio State University research team created an AI deep learning model for predicting treatment probability with patient data including the treatment, outcomes, and potential confounders(干扰因素).
Confounders are related to the exposure and outcome. For example, a connection is identified between music festivals and increases in skin rashes(红疹). Music festivals do not directly cause skin rashes. In this case, one possible confounding factor between the two may be outdoor heat, as music festivals tend to run outdoors when the temperature is high, and heat is a known cause for rashes. When working with real-world data, confounders could number in the thousands. AI deep learning is well-suited to find patterns in the complexity of potentially thousands of confounders.
The researcher team used confounders including population data and co-prescribed drugs. With this proof-of-concept, now clinicians have a powerful AI tool to rapidly discover new treatments by repurposing existing medications.
【1】What do we know about a drug used off-label?
A．It is sold without a label.
B．It is available at a low price.
C．Its uses extend beyond the original ones.
D．Its clinical trials are rejected by doctors.
【2】Metformin and Trazodone are similar as both of them________.
A．are used off-label
B．treat rare diseases
C．result in sleep issues
D．are medical breakthroughs
【3】What can be inferred about “confounders”?
A．They are possible treatments.
B．They are environmental factors.
C．They can be easily recognized in real-world data.
D．They should be taken into serious consideration.
【4】What is the main idea of the text?
A．AI examines benefits of existing drugs.
B．AI identifies off-label uses for drugs.
C．AI finds new drugs for common diseases.
D．AI proves the power of drug research.
29、 Success doesn’t begin until you begin the walk down the way towards your goals.
And your walk down the way always begins first with a baby step. Why do we call them baby steps? Are they really anything more than our next step down life’s way?
Baby steps are the first steps we take as an act of faith. We see others stepping out and we want to show our ability to walk by following them. As we grow, we continue our development by taking extra baby steps. Sometimes we fall; sometimes we fail. After that, all steps become an act of faith; we just become more practiced. If you say to yourself “I don’t want to make a fool of myself” or “I’d better be good at this”, you’ll probably never take the baby steps towards your goals and end up lying in your own self-pity.
As a culture, we focus on results. We think about every risk that must be taken to reach our goals. There are few people who are excellent performers of any tasks the first time they try them. They fail and succeed. Then, they build upon their abilities learned each time. They practice their skills and use their talents through baby steps before they are ready to prove them to the whole world.
So, learn to take those baby steps to reach the goals before you. Know that you can depend on God to show you the way. As you become more experienced, your baby steps become a walk, then a jump, and finally a sprint. That’s how our baby steps lead us through the marathon of life.
【1】In the third paragraph, the writer expresses the view that .
A.we can’t expect to succeed without working hard at first
B.adults should learn from babies in dealing with hard tasks
C.we must make full use of our skills in order to get rewards
D.baby steps play the key role in leading us towards success
【2】The underlined word “sprint” in the last paragraph probably means“ ”.
A.slow rush B.sudden stop C.hard climb D.fast run
【3】What’s the writer’s tone in the text?
A.Light-hearted. B.Regretful. C.Encouraging. D.Concerned.
