The charity has teamed up with the i (a British newspaper) to increase the number of its helpers, which it sends into schools to give children aged 3 to 13 who have fallen behind with their reading or are at risk of doing so support with their reading.

“I think there is an absolute need to reach kids who don't have access to books,” she said. “Just reading for 10 minutes a day improves a child’s achievement at school. Books show children the world is big and varied and full of wonder.”

And Ms Elphinstone knows first-hand how tricky reading is from her own experience. “In class when the teacher said 'could you read aloud', the words would jump all over the page and I’d stumble （结巴）and lose so much confidence,” she said. “That was difficult. Until way after leaving school, I just assumed I needed to put in a lot more work than other people to finish an essay or process information.”

Nowadays she thinks one of the biggest challenges is the competition books face from screens, which are being used by children for everything from videos and games to social media.

“There's so much demand on their time and it’s such an easy, quick-fix demand,” she said. “It's immediate satisfaction. Screens are loud and books whisper with quieter magic, but I think the effects are transformative and they are longer lasting than a Screen.”

This is where she thinks Coram Beanstalk can help, both with reading and also making children Feel valued.

What does salt have to do with bacteria? Two things: First, bacteria need moisture (水分）to grow and multiply. Salt pulls moisture out of food, so the bacteria die. 【2】 If you cover food with salt or very salty liquid, bacteria outside the food die before they get in, and bacteria already in the food are poisoned by the salt that goes inside.

【3】 For meat or fish,you pour on a layer of salt, then rub it in well, leaving a salt crust (盾）all over the outside. Hams are often made this way. Another way is to put food into very salty water, called brine (卤水）.【4】 The salt will draw the moisture out of the food, creating a kind of brine that the food sits in.

Today, in most parts of the world, salting, is no longer necessary. 【5】 But even though we no longer rely on salt to keep our food fresh, we haven’t lost our taste for salt. We don’t want to give up our bacon, corned beef or salted beans.

A.So how do you preserve food with salt?

B.Next, it can make food too salty to eat.

C.Second, salt is poisonous to many bacteria.

D.But for a long time, no one knew why salt worked.

E.You can alternate layers of food and salt in a big jar.

F.People buy food in cans, keep it in the refrigerator, or freeze it.

G.They use salt to preserve meat, fish, vegetables, and even fruit.

【1】 Clean your hands often and carefully with an alcohol-based hand cleaner or wash them with soap and water. Washing your hands kills viruses that may be on your hands.

Keep social distancing. 【2】 When someone coughs or sneezes, he releases small drops of liquid from his mouth or nose which may contain the viruses. If you are too close, you can breathe in the liquid, including the COVID-19 virus if the person coughing has the disease.

Avoid touching eyes, nose and mouth. Your hands touch many surfaces where viruses can survive up to nine days. Once contaminated(弄脏), hands can carry the viruses to your eyes, nose or mouth. 【3】

Promote respiratory hygiene(呼吸道卫生). Make sure that you cover your mouth and nose with your elbow or facial tissue when you cough or sneeze. 【4】

If you have a fever, a cough and difficulty breathing, seek medical care early. Stay home if you feel unwell, even with mild signs of infection such as headache and slight runny nose, until you recover. If you have a fever, a cough and difficulty breathing, seek medical attention, and follow the directions of your local health official. 【5】 This will also help to prevent possible spread of the coronavirus and other viruses.

A.Wash your hands frequently.

B.Then throw away the used tissue in a specially provided dustbin immediately.

C.If not, you are bound to be in a horrible condition.

D.Stay home and never participate in any social activities.

E.From there, the viruses can enter your body and can make you sick.

F.Stay at least one meter away from anyone who is coughing or sneezing.

G.Calling ahead will permit the health official to quickly direct you to the right health facility.

Last Christmas, I wanted to give the woman 【1】 cleans my apartment a nice gift in 【2】 (appreciate). Since I know she doesn’t have much money, I decided 【3】 (write) her a generous check so she could use it however she wanted. I put it in an attractive card with a photo of a cat and a dog on 【4】 (it) cover because she loves animals.

The card came with a nice message, and I also added a personal message in which I thanked her 【5】 her good services, wishing her the best for the coming year and for her dreams coming true.

【6】 (tear) of gratitude rolled down her face when she saw my message, before she even saw the check! She said, “You took the time to write me a personal message; now I feel really 【7】 (love). I’m going to save this card for 【8】 rest of my life!”

This reminds me that what people really want is to be acknowledged and appreciated, and to know that they matter. This is what’s really important when 【9】 (give) a gift. In this case it 【10】 (obvious) was not about the money, but about making a sincere heart connection.

Particulate matter，or PM，is a type of air pollutant consisting of small particles of different sizes. PM2.5 has a diameter of fewer than 2.5 micrometers，about 30 times smaller than a human hair. These particles are so small that they can go into our respiratory system (呼吸系统), resulting in lung and systemic inflammation (炎症) and stress.

The team found that something as simple as a daily vitamin B supplement could potentially reduce the impact of the tiny particles on the human body，although they stressed that the research was in its early stages and the sample size was small.

For this study，10 volunteers were initially exposed to clean air and given a placebo (安慰剂) to check their responses. The group then took another placebo for four weeks before being exposed to heavily polluted air from downtown Toronto，where an estimated 1，000 cars pass every hour. The bad air was delivered to the volunteers through an “oxygen－type” face mask. The experiment was then repeated，with each volunteer taking a vitamin B supplement daily made up of 2.5 mg of folic acid，50 mg of vitamin B6，and 1 mg of vitamin B12. B6 can be found in liver，chicken and nuts，and B12 in fish，meat，eggs，milk and some cereals.

The researchers found that four weeks of vitamin B supplements reduced the damage of PM2.5 exposure by 28%－76%. The results highlight how prevention at an individual level could be used to fight the harmful effects of PM2.5.

【1】Why is PM2.5 harmful to our health?

A.It pollutes and poisons the air.B.It is too much to be got rid of.

C.It carries viruses and diseases.D.It is easily breathed in and damages our body.

【2】What can we infer from Paragraph 3?

A.The process of the research was not scientific.

B.This kind of research has been done many times.

C.Further studies are needed to confirm their findings.

D.Vitamin B is hard to obtain in people’s daily life.

【3】What is the text mainly about?

A.International researchers have a new finding.

B.Vitamin B could reduce the damage of PM2.5.

C.Particulate matter does great harm to our health.

D.Emission control and regulation are badly needed.

【4】The new study was probably published ________.

A.in a science journalB.on a government website

C.in a fashion magazineD.in a medical textbook
