21、On January 7th, 2022, David Bennett became the first person to have a heart transplanted successfully into him from a pig. On that occasion, mere operation success was the goal. This operation is a milestone for xenotransplantation (异种移植)— the transfer of organs from other species to human patients.
For decades, researchers have attempted to deal with xenotransplantation’s basic problem. This is that the human body, when it recognizes foreign tissue, tends to turn against it. In the case of pigs, the most important marker of foreignness is a sugar molecule (分子) called alpha-Gal. While this molecule does not exist in humans, antibodies to kill it do. So no transplant from a pig with alpha-Gal would last more than a couple of minutes in a human body. In 2003 pigs were produced with a changed genome so as to prevent the enzyme (酶) responsible for making alpha-Gal. This was a step in the right direction, but other barriers popped up.
The pig for David’s operation had a genome changed in ten ways to increase the chances of success. Three genes had been removed to reduce the risk of a human antibody rejecting the organ. A fourth, a growth gene, had also been knocked out, to ensure the heart did not enlarge after transplantation. And six human genes had been added to promote acceptance.
There are other concerns. One is any unknown rejection mechanism. Another is the possibility that the organ may pass viruses to its new host. The pig in question was raised where there was no virus to reduce the chance of that, but it remains a possibility.
In theory, pigs can be raised to provide humans with any solid organ, but some will be more complex than others. Moreover, even if these barriers can be overcome, most researchers still acknowledge that increasing xenotransplantation to meet the world’s demand for organs may take decades. After this news, however, the chances that it will happen eventually have increased.
【1】What is the basic problem of xenotransplantation?
A．The human body lacks alpha-Gal.
B．The human body resists foreign tissues.
C．The life of the transplanted organ is too short.
D．The enzyme is prevented from making alpha-Gal.
【2】Why was a growth gene removed in David’s case?
A．Because it would change David’s genome.
B．Because it would lead to heart enlargement.
C．Because it would make the heart more acceptable.
D．Because it would be recognized by David’s antibodies.
【3】What can we learn about the pig?
A．It saved the patient’s life perfectly.
B．It had a decreased number of genes.
C．It had an unknown rejection mechanism.
D．It was raised in a virus-free environment.
【4】What is the author’s attitude towards the future of xenotransplantation?
A．Optimistic.

D．Uncertain.
22、House Sitting
In many countries of the world people do what is called house sitting. It means that if owners of the house are going away, they want someone to come into their home and look after the house and maybe pets while they are away.
In Australia, many people travel. After people retire, they might buy a van and travel all over the country. 【1】
So if someone wants to travel or go away for some reason, they might want someone in their home to care for it and keep the gardens tidy. House sitters might have to care for pets. Also, quite a few people have swimming pools in their back yard and they need cleaning.【2】 I feel it is a great way of seeing the country, because you go and stay in a new city, get to meet new people, and have time to go sightseeing in a new area.
【3】 There are websites where you find the advertisements by people who want to travel, and by replying to the advertisement, you can make arrangements to go and look after their home.
There are some requirements to be a house sitter. You must be a trusted person, so that the home owner knows you will not steal anything. You must be able to go when the house owner wants you to go, so you need lots of free time.【4】 You need to be good with pets, able to care for cats and dogs, or other pets they may have.
Some house sitting jobs are just for a few days or a couple of weeks while the house owners have a short holiday. Sometimes it is for much longer. We have had one house sit for six months, while the home owner travelled to Europe.
【5】 Then you can travel to many different countries and stay there. One of the important things to get is references from the home owners where you have stayed. A reference is a written letter to say that you are trustworthy and have looked after their home well. You can show these letters to possible house sitting jobs and they know you will do a good job.
A．I have done house sitting many times.
B．Thousands of people do this all the time.
C．It is also possible to do house sitting in other countries.
D．Generally you have many opportunities to get a house sitting job.
E．You must take a little care over what your description says about you.
F．This is an international house sitting service for all city and country areas.
G．You must have a good car, so you can travel to different parts of the country.
23、Steve Jobs knew from an early age that he was adopted (收养). “My parents were very open with me about that,” he recalled. He had a clear memory of sitting in the yard of his house, when he was six or seven years old, telling the girl who lived across the street. “Does that mean your real parents didn’t want you?” the girl asked. “My whole world was falling apart,” according to Jobs. “I remember running into the house, crying. And my parents said, ‘No, you have to understand.’ They were very serious and looked me straight in the eyes. They said, ‘We specially picked you out.’ Both of my parents said that and repeated it slowly for me. And they stressed every word in that sentence.”
Abandoned (被抛弃). Chosen. Special. These words became part of who Jobs was and how he thought of himself. His closest friends think that the knowledge that he was given up at birth left some scars (伤疤). “He wants to control everything because of his personality and the fact that he was abandoned at birth,” said one longtime colleague (同事), Del Yocam.“He wants to control his environment, and he sees his product as a part of himself.” Greg Calhoun, who became close to Jobs right after college, saw another effect. “Steve talked to me a lot about being abandoned,” he said. “It caused great pains and made him independent. He was different from others because he was born into a different world.”
Later in life, Jobs became a father and abandoned one of his children. Andy Hertzfeld, who worked with Jobs at Apple in the early 1980s, is among the few who remained close to Jobs. “To understand Jobs, you have to know the reason why he can’t control himself and is sometimes cruel and harmful to others,” he said. “That goes back to being abandoned at birth. The real problem was the theme of abandonment in Steve’s life.”
【1】Which of the following is true about Jobs’ childhood?
A. He left his parents at the age of six or seven.
B. He was shocked knowing he was abandoned.
C. He couldn’t remember how he was abandoned.
D. His parents chose him because his family was poor.
【2】What did Del Yocam think of Jobs?
A. He hated to be born with scars.
B. He liked to get things under control.
C. He enjoyed good working environment.
D. He wanted to influence everyone.
【3】What does the underlined word “it” in the second paragraph refer to?
A. The fact that Jobs was abandoned.
B. Jobs’ pain from the abandonment.
C. Jobs’ talk with Greg Calhoun.
D. The world where Jobs lived.
【4】What can be inferred from the last paragraph?
A. Jobs didn’t bring up any children.
B. Jobs had a lot of close friends.
C. Abandonment influenced Jobs.
D. Nobody likes Jobs’ character.
【5】What is the best title for this text?

24、One of the three astronauts who made up the historic Apollo 11 crew, NASA veteran Michael Collins passed away today, April 28, 2021, at the age of 90.
Collins was born on Oet. 31, 1930, in Rome, Italy. His father, a career officer in the US, Amy who’d go on to retire as a major general, was stationed there at the time. After his family returned stateside, Collins earned a Bachelor of Science degree from the US. Military Academy at West Point, graduating with the class of 1952. He then became an Air Force test pilot, which opened some interesting doors. In 1962, John Glenn became the first American to orbit the Earth. Glenn’s achievement was an inspiration for Collins. “I certainly had no childhood dream of flying to the moon or anywhere else, but the idea was extremely appealing.” Collins wrote in his autobiography Carrying the Fire: An Astronaut’s Journeys. He was selected to join NASA’s third class of astronauts the following year. His first extraterrestrial (地球外的) adventure came in 1966, when Collins set about on a three-day spaceflight with fellow astronaut John Young. Known as Gemini X, their mission was one for the record books; the two men reached the then-unprecedented (前所未有的) altitude of 475 miles (764kilometers ).
Of course, Michael Collins is best remembered for his role in Apollo 11. On July 16, 1969, at 8:32 AM ( Eastern Standard Time ), Collins, Buzz Aldrin and Neil Armstrong were launched out of the Kennedy Space Center in Florida. They were the three explorers NASA had chosen for the first mission that would ever put a man on the moon. Four days into their adventure, on July 20, Collins parted ways with his crewmates. Seated in the Eagle landing craft, Armstrong and Aldrin made their landing onto the lunar surface. An American flag was planted; photos were taken; Armstrong said the immortal words, “ One small step for man, one giant leap for mankind. ”
Meanwhile, Collins stayed behind in the crew’s command module (舱), orbiting the moon as his colleagues explored it.
【1】What motivated Collins to dream of flying to the moon?
