For some people, there’s no better companion than mans best friend-a dog. This four-legged pet can bring

comfort and joy and provide much- needed exercise for you when it needs walkies! This probably explains why

dog ownership increased last year because people spent more time at home during he CovID-I9 lockdown.

However, as demand for a new dog increased, so did the price tag. Popular breeds, such as Cockapoos and

Cocker Spaniels, saw even sharper price increases, and puppies have been selling for $3,000 or more.

Animal welfare charities fearthat high prices could encourage puppy farming, smuggling (走私) or dog theft.

An investigation found some breeders have been selling puppies and kittens on social media sites--something

charities have called “extremely irresponsible”.

But despite some new owners purchasing a dog legally, maybe from a rescue center or registered breeder,

they’ve proved to be ill-prepared for life with a new pet, and the pet itself has found it hard tocome to terms

withlife in a new home.

Looking to the future, there are concerns about the welfare of these much-loved pets. Lan Alkin manager of

the Oxfordshire Animal Sanct uary in the UK, notes: “At the moment, the dogs are having a great time, but

separation anxiety could still surface when people go back to work.” And Cliare Calder from the UKs Dogs Trust

rescue charity says, “The economic situation also means that some people may find they can’t afford to look after

a dog.” The message is not to buy a dog in haste and to pick one that fits into our lifestyle.

As a basic food in the Asian diet，soybeans（大豆）have been used to make tofu and soy milk for hundreds of

years．But now，they are also being turned into an alternative to plastic wrap．

William Chen，a professor of foodscience and technology at Singapore's Nanyang Technological University，invented the environmentally﹣friendly food wrap．It's made of cellulose（纤维素），a form of fiber，obtained from

the waste generated by soy bean product producers．The beans are pressed tosqueeze out juice that's used to

make tofu and soy milk．And what's left is usually thrown away，but Chen takes the waste and puts it through a

fermentation（发酵）process，during which cellulose is produced．

Cellulose﹣based plastic wraps have been on the market for a few years，but Chen says that most are made

from wood or corn，grown for that purpose．By contrast，his wrap is made from a waste product，which doesn't

compete with other crops for land and is more sustainable．Chen's technology could help to solve two problems at

once：cutting plastic production and reducing the amount of food waste．"In Singapore，the amount of food waste

generated every year could fill up 15，000 Olympic﹣sized swimming pools，" Chen says．

F&N，a soy﹣based drinks producer，has partnered with Chen's lab and provides the product，straight from

the factory．The company is conducting a study to assess whether the food wrap could complete commercially

with conventional products．Chen adds，"The soy﹣based wrap costs almost nothing to makein the lab because

the raw materials are free．Commercial production would involve additional expenses，such as storage and quality

control，however，we have not calculated those costs yet．"

Chen hopes neighboring soy﹣loving countries will be inspired bySingapore to adopt his innovation．"My

dream is that our technology，which is cheap and simple，will cut plastic and food waste and create a cleaner

environment，" Chen says．

4. What is the second paragraph mainly about？

A. The introduction to William Chen．

B. The process of producing soy milk．

C. The way to make soy﹣based wrap．

D. The benefit of eating soy products．

5. What's the biggest difference of Chen's wrap from other cellulose﹣based plastic wraps？

A. It saves land for industry．

B. It's more easilybroken down．
