In the 19th century, an Arab physician known as Zuhr Ibn conducted some animal research to assess the surgical procedures that could be applicable in humans. Since then, animal testing has been considered to be the most efficient way to develop new drugs. New medical treatments and drugs are tested in animals first to determine their effectiveness or safety levels before they are finally tested on humans. However, it remains controversial whether it is morally right or wrong to use animals for medical or commercial experiments.
Use of animals for medical purposes is seen to be necessary by many scientists. Researchers usually begin their trials using rats. If the tests are successful, further tests are done on monkeys before using human beings. For testing, such tiered(分层的) rounds are important because it reduces the level of error and any negative side effects. Some argue that animal testing has contributed to many life-saving cures and treatments and there is no adequate alternative to testing on a living, whole-body system. Moreover, there are regulations for animal testing that limit the misuse of animals during research, which serves as evidence that animals are well taken care of and treated well instead of being intentionally harmed.
However, some other experts and animal welfare groups have opposed such practice, terming it as inhumane(不人道的) and claiming it should be banned. According to Humane Society International, animals used in experiments are commonly subjected to force feeding, radiation exposure, operations to deliberately cause damage and frightening situations to create depression and anxiety. They also hold the view that animals are very different from human beings and therefore make poor test subjects. Drugs that pass animal tests are not necessarily safe. Animal tests on the arthritis(关节炎) drug Vioxx showed that it would have a protective effect on the hearts of mice, yet the drug went on to cause more than 27,000 heart attacks before being pulled from the market.
It’s safe to say that using animals for tests will continue to be debated in many years to come. Despite the benefits of animal testing, some of the animal welfare organizations’ concerns need to be addressed with adequate regulations to ensure that animals are treated humanely.

It’s funny how readily we “take the advice of complete strangers” when shopping online. More than 80 percent of Americans say they read online reviews at least some of the time. But on sites such as Amazon and Yelp, businesses have learnt to “making the most of the rating system to the seller’s or the platform’s advantage”, eventually “making the star-rating scale useless”. Even in the case of confirmed reviews, it can be hard to know what the stars mean.
Amazon has stepped up the effort to provide transparency said Louise Matsakis in Wired.com. Its “Vine voices” program sends free products for testing to an invite-only community of “trusted reviewers”. Amazon has also started ranking its Top 10,000 Contributors on a daily leaderboard not “just by the number of reviews a person has but also by how many customers found their feedback to be helpful”. The current No.1 reviewer, a 45-year-old from North Dakota who has posted nearly 2,500 comments since 2002, has owned a bakery in Oregon, worked for a small newspaper, and had a 10-year stretch in the Navy as a nuclear welding inspector. Now he spends his time testing everything from fryers to popcorn makers, though he exceeded its weight limit by 70 pounds.
But sellers are still finding ways to deceive prospective buyers, said a reviewer. He said, “I identified more than 150 private Facebook groups where sellers openly exchange free products for five-star reviews. I joined four of them and was annoyed with a flurry of private messages from sellers. One offered to pay me $10 for a splendid review of what was already ‘one of the highest-ranked iPhone chargers’, with 3,971 five-star reviews and a trusted ‘Amazon choice’ label. When it arrived, the charger broke within minutes. I reached out to Amazon and those thousands of five-star reviews for the charger disappeared.”
The product now has 11 reviews and holds a rating of 2.5 stars. But before all those five-star reviews disappeared, how many shoppers spotted this $ 13.99 charger pack on Amazon’s first-page results and fell for the trick?
1.What action has Amazon taken to make the star-rating scale useful?
A.Provide effectively checked comments for consumers.
B.Give priority to the advantage of customers.
C.Decide on contributors’ rank by the quantity of reviews.
D.Get reliable reviewers to test products before their release.
2.What does the underlined word “deceive” in the third paragraph most probably mean?
A.Persuade. B.Instruct.
C.Interest. D.Cheat.
3.What do we know about the charger seller in the last two paragraphs?
A.He convinced buyers to obtain free products.
B.He attempted to obtain excellent reviews by purchase.
C.He was in hot water and deleted all untrusted reviews.
D.He tricked buyers and disappeared from Amazon.
4.Which of the following would be the best title for the passage?
A.The Efforts of Amazon
B.The Application of Rating System
C.Not Every Star Shines So Bright
D.Don’t Fall for the Trick of Sellers
I was 11 years old when I asked my mom for piano lessons in 2010. We were in the economic decline. She said a polite “no”.
That didn’t stop me. I Googled the measurements for a keyboard, drew the keys on a piece of paper and stuck it on my desk. I would click notes on an online keyboard and “play” them back on my paper one-keeping the sound they made on the computer in my head. I spent six months playing without touching a real piano. Once my mom saw that I was serious, she borrowed money and bought me 10 lessons.
I still remember the first one. I was struck by how real the sound of the piano was. I sat my grade one after eight lessons. Once I started secondary school, we couldn’t afford lessons again. I passed grade three, then grade five, practicing only on my piece of paper.
One evening, when I was about 13, my mom said she had a surprise for me; it was an electronic keyboard, bought with more borrowed money. It was the first time I’d played for her. She was in shock.
My school didn’t offer music A-level. I found the Purcell School for young musicians. But I had to pass a difficult test. Some of the questions involved an evaluation of the composer or when some piece was written. I felt overwhelmed. To my amazement, I was offered a place.
At Purcell, I spent two years working as hard as I could. I performed to raise money and saved enough to buy my first piano.
When I left Purcell, I was awarded the senior piano prize and senior academic music prize. I am now at the Guildhall School in London. I feel proud: it’s been 10 years since I drew my paper piano, and I’m at one of the world’s leading music schools.
The irony is that I continue to do a lot of my practice away from the piano-what we call mental practice. The paper piano helped arouse my curiosity about how music works, the building blocks that form the pieces.

During the National Day holiday, my parents and I paid a visit my grandparents by train. There was a large number of people and the train was crowded, but everyone helped those who had lots of baggages and behaved politely. Along the way, we enjoyed beautifully views. At the first, we saw one hill after another. Then what came into view were fields with green crops. After a six-hour trip, they arrived at our grandparents’ house. Exhausted although I felt, I was happy to see my grandparents, which I hadn’t seen for a long time. It’s really an excited trip because it was the first time that I had taken so a long-distance train.
