China Ends Zero-COVID; Oysters Help Clear The Waters In Hong Kong.

COY WIRE, CNN 10 ANCHOR: Hello, lovely people. It`s Thursday. So happy Friday eve. It`s your boy Coy, Mr. Clean, but I keep it cleaner.

Let`s keep crushing it this week each day aiming to be a little better than the day before. This is CNN10 and it`s time to fuel our minds.

We start with an update. China is scrapping some of its most controversial COVID rules, moving away from their strict zero COVID policy which have
 

scrap [skræp] v. 将……拆毁；废弃

caused people mental and emotional stress and strain.

Earlier this month, protesters took to the streets in a rare display of defiance against the country`s ruling communist party. The people are reeling

defiance [dɪˋfaɪəns] n. 反抗；蔑视，藐视；挑战

reel [ril] v. 发蒙；感到眩晕; 踉跄；蹒跚

from the effects of the government placing millions of people under lockdown and limiting access to loved ones, food and even medicine. All

this on top of the economic strain it`s caused.
 

on top of: in addition to, following closely on

China`s zero COVID policy has kept the nation`s infection rate lower than countries like the United States by isolating every case of COVID and

shutting down the surrounding areas. But easing restrictions now marks a significant step in the government`s plans to reopen the country.

This week, the Chinese government announced 10 new guidelines that loosened restrictions, most notably allowing people with COVID to quarantine at home

instead of being taken to an isolation facility, a practice which previously frightened its citizens. The government is also dropping
 

drop [drɑp] v. 中断；停止

mandates that required proof of a negative COVID test to enter public places. These are some of the significant steps which should offer relief

to China`s residents after nearly three years of disruption to their daily lives and economic futures.

But there`s still concern. Twenty-five million people in China have not received a coronavirus vaccine. If there`s an influx of new cases, it could
 

influx [ˋɪnflʌks] n. 湧進；流入，注入

overwhelm the hospital system, leading to a potentially tragic situation for citizens.

Our Selina Wang has more.

SELINA WANG, CNN INTERNATIONAL CORRESPONDENT: This is the kind of line Beijingers stand in, outside in the cold to get their COVID tests. A 48-

hour test is required to get into most places.

But there aren`t many places to go. Much of Beijing is still closed down. This is one of the most popular tourist places in the city. But the

restaurants are largely closed, and the malls are pretty empty.

So, this McDonald`s is still open but for takeaway only. But even to get takeaway, you`ve got to prove that you`re clear of COVID.

Here`s how I do it. I open up the health app on my smartphone, I scan the QR code.

So, it says, I`ve got a green code, and I`ve got a recent COVID test, so I`m good to go.

This code dictates all of our daily lives in China. Green means good to go. Red means I may have to isolate at home or go to a mass quarantine

facility. This allows China to track the movements of virtually all 1.4 billion people in the name of contact tracing.

I`ve got to scan my code to get into a taxi, a public park, a mall, or a coffee shop. Even a public bathroom.

(voice-over): I ran into a group of delivery people on the street. They`ve got to do COVID tests every single day to do their jobs.

This woman tells me the pandemic has been hard on her. I ask her why. She says it`s because she`s scared of the virus.

Getting COVID in China is unlike anywhere else in the world. You and your close contacts all get sent to a quarantine center. This is a convention

center in Beijing that`s been turned into a massive quarantine facility with thousands of beds.

But some of these facilities in the country, they are in very run-down and unsanitary condition. And then your whole building or community could go
 

run-down [ˌrʌnˈdaʊn] adj.（建築物或地區）破敗的，破舊的，失修的; in poor physical condition

unsanitary [ʌnˋsænə͵tɛrɪ] adj. 不卫生的；有碍健康的

into lockdown.

I spoke to a man who`s been in and out of quarantine six times already just this year. He tells me his whole building of more than 200 families went to

a quarantine facility last month, because they were considered close contacts. He says he`s not scared to get COVID because omicron is less

severe and his whole family has been vaccinated.

I approached a few people just released from this mass quarantine center here. I ask if they had tested positive for COVID. Yes, the man nods and

says they have recovered. "How many days did you spend in there?" I asked. "Seven days," he said.

Unprecedented protests recently erupted across China.

They are chanting that they don`t want COVID tests, they want freedom.
 

chant [tʃænt] v. 反复（单调）地唱（或说）；吟诵

Authorities swiftly cracked down on the protesters. But they are finally softening their stance on zero COVID. Some cities are lifting lockdowns,
 

soften [ˋsɔfn] v. 使变柔软；使变和蔼

changing COVID testing requirements. Under some conditions, people can now quarantine at home if they have COVID, which is a huge deal.

But this country has already built up a whole infrastructure around zero COVID, spending all of its resources on quarantine facilities and COVID

testing.

So it`s going to be a long and slow exit from zero COVID.

WIRE: Ten-second trivia:

In the animal kingdom, oysters are classified under what phylum?
 

phylum [ˋfaɪləm] n. 【生】门

Mollusca, arthropoda, chordata or porifera?

WIRE: Did you know that scientists estimate that oysters have been around for 15 million years and they`re far more valuable than the beautiful

pearls that they can produce. The reefs that take shape as they grow together create a shelter where hundreds of other species can flourish.

They`re also crucial for ocean health, filtering the water around them. One oyster can filter 50 gallons of water per day.

Let`s hear now from conservationists who are hoping to be successful in restoring Hong Kong`s famous oyster reefs in CNN`s Call to Earth.

(BEGIN VIDEOTAPE)

KRISTIE LU STOUT, CNN CORRESPONDENT (voice-over): Tucked away in the northwest corner of Hong Kong with the high-tech Chinese mega city of
 

tuck away 躲藏

tuck [tʌk] v. 舒服地裹在里面

Shenzhen in sight is a rich habitat that is home to mangroves, soft, muddy shores and oyster reefs that date back centuries.

For over 700 years local farmers cultivated oysters here in the mud flats of Pak Nai and recent decades, traditional oyster farming has declined due

in part to coastal reclamation and over harvesting.
 

reclamation [͵rɛkləˋmeʃən] n. 开垦

But conservationists like Marine Thomas have discovered that reintroducing oysters to the abandoned reefs can boost biodiversity and strengthen these

shores.

MARINE THOMAS, SENIOR CONSERVATION PROGRAM MANAGER, THE NATURE CONSERVANCY: Usually, people will associate oysters with food but less known is that

oysters and other shellfish create habitats. They create reef habitats. In fact, just like coral reefs, they will bunch together and create these hard

structures that you can actually walk on.

STOUT: In a survey of the city`s coastlines, researchers from the Nature Conservancy at the University of Hong Kong discovered existing reefs like

these old farms could potentially act as a source of oyster larvae. They also found that a single Hong Kong oyster can filter up to 30 liters or 8
 

larva [ˋlɑrvə] n.【動】幼蟲；幼體 (larvae : larva的名词复数)

gallons of water an hour, one of the highest filtration rates recorded for the species.

Another finding, the reefs host six times more species and bare mud flats as the piles of shells provide shelter for worms and small crabs,

attracting a variety of animals including birds like this little egret.
 

egret [ˋigrɛt] n. 白鹭

And yet another benefit is mitigating the effects of climate change, so how does the humble oyster do that?
 

mitigate [ˋmɪtə͵get] v. 使缓和；减轻

THOMAS: So the humble oyster will also help us fight climate change if it`s in a reef structure so if it`s in a hard reef structure that is

creating a barrier, think of it as a natural sea wall then it`s going to be creating friction on the sea bottom that will attenuate wave action and
 

friction [ˋfrɪkʃən] n. 摩擦；摩擦力

attenuate [əˋtɛnjʊ͵et] v.（使）变小

therefore also flooding at the back of it.

STOUT: Since 2020, Thomas and a team of volunteers have been at work restoring this abandoned oyster farm. They dry old shells in the sun before

returning them to the water to form a base for oyster larva to attach to. They hope to introduce millions of oysters to help revitalize the area over

the next few years.

ASHLEY HEMRAJ, MARINE BIOLOGIST, THE SWIRE INSTITUTE OF MARINE SCIENCE, THE UNIVERSITY OF HONG KONG: One of the biggest things that always amazes me

and makes me happy is seeing all the number of crabs here, especially here as you walk, the crab walks away. It`s -- if you fix on it, it`s quite
 

fix [fɪks] v.（目光等）注视

amazing to see this. It is really, really beautiful.

STOUT: As new oysters grow, they clean the water, provide shelter and food for wildlife and join forces with the mangroves as a coastal buffer.
 

buffer [ˋbʌfɚ] n. 缓冲区

A spectacular sunset descends on Pak Nai as these small briny creatures work to build an ever more vibrant ecosystem.
