Not long ago , Richard Denniston found himself suffering the same pain that millions of other pet owners have faced . His little Scottish dog had a brain tumor(肿块)and would soon die. Like others who faced the problem before him , Denniston just wanted to end his pet’s suffering . However , he took one step further.
Deniston , an expert who studies animals , collected a tiny skin sample from the dog and took it to his laboratory at Louisiana State University. There he cultivated it and froze it in liquid nitrogen.
From that idea , Denniston started a new technology .Denniston’s company will save pet’s DNA $500,plus a monthly storage fee of Us $10, until cloning becomes a reality .
Thanks mostly to the contribution of a California multimillionaire , that day may not be so far off.
“It could happen extremely soon if everything went on well.”says Mark Westhusin , a professor leading a dog cloning team . Most experts put successful dog cloning a year to five years down the road . The cost is bound to be expensive at first , but it would eventually drop to a few thousand dollars.
Since Dolly , the sheep which was first cloned in 1997 ,cattle ,goats ,mice and monkeys have been cloned in labs . Pets are likely to be next.
“I really believe that the technology is going to become available for many species in the near future ,”Denniston says .

Not so long ago, a sailor sailing across the cold waters of the northern Pacific Ocean might have had every chance of meeting a sea cow. This cow would have measured 10 meters long and weighed between five and 10 tons and it would spend most of its day moving slowly in the seas, eating grass growing underwater. The cow in question was known as Steller’s sea cow, which has now died out.
Today, many people don’t know that such a strange creature once existed, or don’t know its unbelievable story. but many scientists have discovered many fundamental facts about this mystical (神秘的) animal.
Surprisingly, the first recorded sighting of a Steller’s sea cow didn’t happen until 1741. When a sailing expedition (探险) was stuck on an uninhabited island, later named Bering Island. The sailors survived by hunting and eating the enormous sea cow. Like its modern relatives, the sea cow lived in groups. That and its slow moving behavior made it easy to be caught.
Those sailors that escaped from the island spread word of the amount of meat to be found off its shore. As a result, more and more people came to hunt the animals. It is said that one sea cow could feed 33 men for a month.
However, just 27 years after the island and species had been discovered by modern man, the last sea cow was reported killed. This makes the sea cow one of the few truly large mammals known to have been driven extinct in the modern age.
1.What does the underlined phrase “in question” in Para 1 mean?
A.In danger. B.Referred to.
C.In doubt. D.Being questioned.
2.When did the Steller’s sea cow become extinct?
A.In 1717. B.In 1741.
C.In 1768. D.In 1775.
3.Which of the following words can best describe the Steller’s sea cow?
A.Endangered. B.Huge.
C.Strange. D.Mild.
4.What is the text mainly about?
A.An unbelievable story about the Steller’s sea cow.
B.When the Steller’s sea cow became extinct.
C.How the Steller’s sea cow has been driven extinct.
D.The discovery about the Steller’s sea cow dying out.

Online shopping started not so long ago. Tim Berners-Lee invented the World Wide Web in 1990. The first online bank opened in 1994. In 1995, Amazon started operating and is now one of the largest online shopping malls. Then in 1996, eBay started its online shopping site.
By sitting at home you can now buy anything from knives to cars. The worry you may have about traveling and parking can be avoided while you shop online. With online shopping, you need not worry about the weather. Online shops have no holidays, closing times or any other problems. You can shop 24 hours a day, 7 days a week and 365 days a year. Some online shops also keep customers’ opinions about each product, so you can easily find out what other customers think about the product before buying it.
When you go for real-world shopping, you can actually touch and feel it, but in online shopping you can only see the pictures. Also if you are shopping online, you have to be careful with your credit cards.
The first step in online shopping is to search for what you want to buy. Once you find the required product, put it in a “shopping cart” and continue shopping. After you have got enough in your “shopping cart”, check out the product. You can add or take out the products in your shopping cart. The next step is to login(登录) using a username and a password. Enter the address where you want the product to be sent. Some sites even ask for your email, phone numbers, etc. Then wait for the confirmation(确认)of your order. You can also cancel the order if needed. Online shopping is a different experience and you can make shopping online easy when you get used to it.
51. When shopping online, you can _______.
A. buy anything wherever you go B. park your cars where you want to
C. touch anything you want to buy D. know what others think of the product
52. The second paragraph mainly tells us ______.
A. the things people can buy in online shops
B. people can know different opinions of customers
C. people can do online shopping at their own homes
D. the advantages people can have through online shopping
53. From the text we can know that ______.
A. customers needn’t have a username to buy something online
B. customers must give their emails as well as their phone numbers
C. customers should be careful with their credit cards when shopping online
D. once customers put the products in their “shopping carts”, they can’t change them
54. If you want to buy a cup online, what is the right order of the following things you can do?
a. Enter the address
b. Search for a right cup

A long time ago, and still in some countries today, the dollar and penny did not even exist. Actually, trading a cow for two pigs is still the norm (常态) for many cultures. So how is it that we get to use paper and coins?
The biggest challenge for ancient cultures was to have a system that would allow people to exchange products with each other. However, the problem came up when one person was in need of something immediately that they didn’t have a product to trade. For example, a farmer that needed wheat only had fruit to exchange but the fruit wasn’t ready to hand over for another two months. This is what started the idea of a “common currency”. The farmer could buy what he needed with “currency” and just as important, the value of the goods he was exchanging was standardized. He did not have to worry about giving anything in return now or later; his deal was complete. Thus “money” was born.
Over time, each country has developed its own currency and something that might cost 1,000,000 lire in one country might be 1 dollar in the US currency. Most countries also frequently use powerful political people as the “face” of their currency. The US currency is the best example of this. Can you name all the presidents that currently appear on not only paper money but also coins?
The real excitement, however, is the future of how we buy things. People have started to use debit cards (借记卡) that allow you to pay using your bank account rather than cash. That has given way to something called Mondex. Mondex allows you to “wave” your card past any special device that can read these cards. You no longer have to insert, swipe (刷) and then punch in numbers, which could cause security problems.
1.What’s the purpose of Paragraph 1?
A.To introduce the topic of the text.
B.To explain what money was like in history.
C.To tell us that there was no money long ago.
D.To compare the difference between a cow and two pigs.
2.The farmer had an idea of using currency when ________.
A.he had a product to exchange B.he had made a lot of money
C.he had nothing to trade for what he needed D.he would harvest his fruit
3.Mondex is a kind of card which can ________.
A.keep you safe if you are in trouble
B.save you a large amount of money
C.help you trade safely and conveniently
D.make you happy whenever you are bored
4.What does this passage mainly talk about?
A.The evolution of payment. B.The trade in ancient times.
C.The use of money in the world. D.New ways of payment.

Not too long ago, our teacher, being a “tree-hugger”(as the kids call her), had us write an essay on an environmental issue. I was eager to start, but something made me stop.
“What is an environmental issue?” one kid asked. “What if we don’t care about the environment?” another complained. “It’s not like it affects me.”
These comments astounded me. I have always cared about the environment and assumed that others did too. From the surprised look on my teacher’s face, I could tell she felt the same way.
In no time, I finished my essay. In my essay I wrote about logging(伐木), which is an important industry, but if we continue to cut down trees without replacing, it will damage the environment.
There are so many things that we can do to save our world. Recycling, of course, is always a good thing, but not everyone has a recycling plant nearby (I don’t). There are other ways to help the environment. Plant a tree. Don’t waste water.
I can’t stand it when a person’s excuse for not caring is “Nothing is going to happen in my lifetime, so why should I care?” Sure, the chances of something terrible happening are slim, but I want people to realize that if we don’t deal with it, someone will have to eventually. Do you want that to be your children? Or your children’s children?
When my teacher told me to read my essay to my class, I was a little embarrassed because I didn’t want everyone to call me “tree-hugger”. I realize now that if being a tree-hugger means you care about the environment, I’m a tree-hugger 100 percent. I just wish more people were.
1.Why do the students call their teacher “tree-hugger”?
A. She likes hugging trees.
B. She knows a lot about trees.
C. She grew up in the countryside.
D. She cares a lot about the environment.
2.At the beginning, the author stopped writing _____ .
A. to ask some questions
B. because of other kids’ comments
C. to listen to the teacher’s instructions
D. because he had no idea about the topic
3.The underlined word “astounded” in Paragraph 3 can be replaced by “_____” .

4.Paragraph 5 is mainly about _____ .
A. what we can recycle
B. how we can save the earth

D. the author should have written a better essay

Pamela Simpson is 53,“not sporty” and has suffered from asthma(哮喘) all her life. Two years ago her son Jay-Teale, now 10, took up BMX(自行车越野赛).“I enjoyed watching him and thought I'd like to try it,” Simpson recalls. “But I didn't want to embarrass myself. I hadn't ridden for over 40 years.”
Then she noticed a session for women and girls at Burgess Park BMX Track in Peckham, south-east London, where Jay-Teale trained. This season Simpson raced at the London BMX series and finished third in her category.
“It was the most worrying experience of my life. But it was also exhilarating,” she says cheerfully. “My son is proud of me. We now share a real love for the sport. It has brought us closer together.”
Since becoming part of the Olympic Games in 2008, the popularity of BMX has risen. A program introduced in London in 2011 by the sports development charity Access Sport has seen tracks built in several London regions, backed up with investment in coaching, and the program is being rolled out to Bristol.
Mavolwane Wright's children Skye,11 and Xander,10 are sponsored riders who have represented Great Britain in every world championship since 2014. Mavolwane Wright says she was motivated to start BMX herself out of an interest aroused by watching so much of it. “It's an eye-opener to share your children's interests,” she explains. “You comprehend what they go through in a much more direct way. It adds another dimension to your relationship.”
It is also a high-impact sport and the risks are fairly obvious. “I totally get the fear,” says Emma Budgens, 51, a BMX exercise coach and cycling instructor. “It's the fear of doing something new, of getting hurt. But I say, ‘Come and give it a try.’ The chance of having an accident is slim, and you can spend time on the flat to improve your confidence.”
1.What can we learn about Pamela Simpson from the first two paragraphs?
A.She tended to be inactive. B.She performed poorly in the race.
C.She used to feel awkward in public. D.She trained at Burgess Park BMX Track.
2.What does the underlined word “exhilarating” in Paragraph 3 mean?
A.Annoying. B.Inspiring.
C.Thrilling. D.Challenging.
3.What benefit did Simpson and Wright get from BMX?
A.More life skills. B.Stronger will.
C.More confidence in themselves. D.Better parent-child relationships.
4.What does Emma Budgens think of BMX?
A.Risky but actually secure. B.Demanding but open to all.
C.Competitive but instructive. D.Pleasant but time-consuming.
