Dear Lucy,
I was delighting to receive your letter. Thank you for the English dictionary you bought it for me. I received it this morning. There is no doubt that it is of great helpful to me. I’m deeply grateful for your advice what I should pay more attention to practice my spoken English. I’ve made up my mind to speak English both in and out of class. Next month I’ll take trip to Australia, which is organizing by my school. I hope I can practise my spoken English there as many as possible. By the way, I am sending you a set of stamp with this letter, and I’ll send you more if I got any. I do hope you will have a good holiday.

If you need to prove who you are in China, you’ll usually need to use an ID (identity) card. It shows your name, date of birth, address, nationality, photo and ID number. 1.
On April 17, Alipay introduced its first electronic ID card. The card is an electronic version (版本) of a real ID card and is recognized by the Ministry of Public Security. 2. Users can simply select “Web ID” in the app and follow the instructions.
The electronic ID card can now be used in Hangzhou, Quzhou and Fuzhou. People in these cities can use the card to check into hotels, buy train tickets and do other tasks. 3.
About 4 million people will be able to use the service within the next year. “4. Even if they forget their ID cards, they can still get things done. Since the process is simplified, it also makes things easier for government offices and companies,” Tang Feifan, mayor of Quzhou, told Zhejiang Online.
It’s safe to use Alipay’s new service, in case you’re worried that someone might steal your identity. 5. Then, you have to pass both a fingerprint and facial recognition scan (扫描) before you can use the electronic ID card.
A. This gives people another choice.
B. But now, you can prove your identity using your smartphone.
C. First, you must unlock your phone, and enter your Alipay password.
D. It’s quite easy to get an electronic ID card by using the Alipay app.
E. But not all people have welcomed the electronic ID cards.
F. They don’t have to show their standard ID card anymore.
G. The safety of the electronic ID card is the main concern.
Heart disease is one of the major killers in the world today. Many who suffer from it must have heart transplants (移植). However, it’s difficult to get a suitable heart donation, and even if a patient survives the wait, his or her body often rejects (排斥) the heart.
But there is now new hope for sufferers of heart disease. According to a study published in the journal Advanced Science, researchers from Israel’s Tel Aviv University printed a 3D human heart on April 15.
“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” professor Tal Dvir told CNN.
Unlike the previous 3D-printed heart structure, the new heart is complete with cells, blood vessels (血管), chambers (心室) and other structures a heart needs to function normally. But scientists still have more to figure out before the 3D-printed heart can be fitted into the body. For one thing, the experimental heart is only the size of a thumb (拇指). And, although it can contract (收缩) like a muscle, it cannot pump out blood like a real one. At present, the heart prototype (样品) is like a tiny airplane that has all of the right parts, but can’t fly.
However, the development is still regarded as a major breakthrough in medicine.
In the experiment, the researchers turned human fat tissue (脂肪组织) into human heart tissue with stem cell (干细胞) technology. The tissue was then turned into “bio-ink” for a 3D printer to ensure that tissue in the heart came from the patients themselves. So ideally, if it were to be placed in the body of someone in need of a transplant, there would be less risk of organ rejection.
“Patients will no longer have to wait for transplants or take medications to prevent their rejection,” researchers told USA Today. “Instead, the needed heart will be printed, fully personalized (个性化的) for every patient.”
But the scientists think that 3D printing can be used to create other human organs. They foresee a time when the 3D printing of organs will be an everyday medical practice.
“Maybe, in 10 years, there will be organ printers in the finest hospitals around the world and these procedures will be conducted routinely,” Dvir said.
1.Why is the 3D-printed heart important?
A.It will be used on a patient.

D.It has a complete heart structure.
2.What problem do 3D-printed hearts have?
A.They cost too much. B.They are too small.
C.They can’t contract. D.They are hard to produce.
3.Why would there be less risk of organ rejection with the 3D-printed heart?
A.It would be made with stem cell technology.
B.It would be made from human fat tissue.
C.It would come from a patient’s body.
D.It would be printed according to the patient’s condition.
4.What attitude does Tal Dvir hold toward the future of 3D printing of organs?
A.Confident. B.Doubtful.
C.Worried. D.Confused.
