    A person has been badly injured in a car accident. It is necessary to give him a transfusion (输血) because he has lost much blood in the accident. However, special care must be taken in selecting new blood for him. If the blood is too different from his own, the transfusion can kill him.
    There are four basic blood groups: A, B, AB and O. A single test can tell us a person's blood group. Everybody is born with one of these four blood groups. People's blood group, like hair colour, is inherited (继承) from parents.
    Because the substances contained in each group are different, transfusion must be given carefully. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can be given to any other group, so it is often called the universal donor. On the contrary, AB is sometimes called the universal recipient (接受者). However, before being given the transfusion, patients usually receive only salt or plasma (血浆) until their blood can be matched as exactly as possible. In this way, it is possible to avoid any bad results of the transfusion.
    There is a relationship between our blood groups and our nationalities. Among the Europeans, about 42 percent are blood group A while 45 percent are blood group O. The rarest is blood group AB. However, some American Indian groups are nearly 100 percent blood group O.

(1)、Which of the following shows the correct relationship in blood transfusion? (→ =" giving" blood to)

A、 B、 C、 D、
(2)、Usually, before being given a transfusion, ________.

A、a person needs to receive salt or plasma first B、a person needs to have a good rest C、a person needs to have a lot of food and water D、a person needs to find the person with the same blood group as him
(3)、The third most common blood type among the Europeans is _______.

A、A B、B C、AB D、O
(4)、Which is NOT right according to the passage?

A、A person's blood group depends on his parents. B、There is only one kind of blood group in a person's body. C、About 13 percent of the Europeans have blood group AB. D、Most of American Indians can be universal blood donors.
(5)、Which is the best title for the passage? 

A、Blood transfusion B、Blood groups C、Car accidents D、Blood group and nationalities

Not everyone is born smart or good at sports. But everyone can study to become smarter and train to get better at sports. Science shows that anyone can get better skills.

Your brain is made up of billions of neurons(神经元). They are all connected and send messages to each other. Scientists have found that when we learn, neurons make new connections and old connections grow stronger. But if connections aren't used, they will break down. So learning is like exercise for your brain.

A mindset is a way of thinking. Some people have a fixed mindset. They think they are either smart or stupid and they will stay that way forever. Other people have a growth mindset and they think they can learn and get better.

According to Dr. Carol Deck's studies, people with a fixed mindset worry about grades. They're afraid of looking stupid when they make mistakes and try to find different ways of solving problems. They ask for help when necessary. In only two years, babies learn to walk, talk and feed themselves. They never worry about looking stupid when learning. If they make mistakes, they just try again.

Deck's team discovered that kids can choose to have a growth mindset. They can do better in school. So notice what mindset you have. If you ever think yourself stupid, it's not true. You just have not learned how to do something yet.

The sun is setting,brightening your kids' faces as they play in the waves.You reach for your phone for this perfect moment.But before you do,here's a bit of surprising science:Taking photos is not the perfect way to keep memory as you think.

Taking too many pictures could actually harm the brain's ability to keep memories,says Elizabeth Loftus,a psychology professor at the University of California

Photos may outsource memories.It works in two ways:We either shake off the responsibility of remembering moments when taking pictures,or we're so distracted(分心的)by the process that we miss the moment altogether.

The first explanation is the loss of memory.People know that their camera is recording that moment,so they don't try to remember.Similarly,if you write down someone's phone number(不假思索地)because your brain tells you there's just no need.That's all well and good — until that piece of paper goes missing.

The other is distraction.We're distracted by the process of taking a photo — how we hold our phone,composing the photo,such as smiling faces,all of which uses up our attention that could otherwise help us memorize.

However,taking photos can benefit memory — when done mindfully.While taking a photo may be distracting,the act of preparation by focusing on visual details around has some upsides.

When people take the time to zoom in (拉近镜头) on specific things,memories become strengthened.

Another benefit is that we recall moments more accurately with the photos.Memory has been reshaped with the help of new information and new experiences.Thus,photos or videos help us recall moments as if they really happened.

Memories die away without a visual record backing them up.Therefore,a photo is an excellent tool to help remember when done purposefully,which is worth exploring further.

 阅读下面短文,在空白处填入一个适当的单词或括号内单词的正确形式。

 The sanfu period (时期) or"dog days of summer" means the hottest part of summer in Chinese lunar calendar(农历). It was {#blank#}1{#/blank#} July 15 to Aug 14 in 2024. According to traditional Chinese medicine (TCM), sanfu period is{#blank#}2{#/blank#} excellent moment for health care and treating illnesses.

A man named Xu Maolin told his own experience, "I {#blank#}3{#/blank#} (have)a runny nose since I was little. I used to suffer from it every morning and evening during autumn and winter. That was painful. Last year,I tried sanfutie for the{#blank#}4{#/blank#} (one) time and I felt much better. This {#blank#}5{#/blank#} (complete) changed my opinion about TCM. I think TCM has a deep understanding of the human body. I want to make {#blank#}6{#/blank#} (far) studies about TCM by reading more books. It's important to learn to improve {#blank#}7{#/blank#} (I) whole health."

 Nowadays, young people may be worried because of difficulties in life, and{#blank#}8{#/blank#} (health) habits like staying up late often make them feel uncomfortable. TCM works well in treating illnesses. The {#blank#}9{#/blank#} (wise) of TCM in keeping healthy is invaluable. Technology is changing fast, {#blank#}10{#/blank#} the traditional medicine is still important. It's our duty to pass it down and keep it alive.
