The most common disease in the world is the cold. It often starts with a sore throat(咽部疼痛). You sneeze (打喷嚏) and your nose runs. You usually have a headache, too. Often you have a cough later. It's not a serious disease, but you can feel quite bad.
There isn't a cure (良药 ) for a cold, but you can take medicines to make you feel better. For example, you can take aspirin (阿司匹林) to get rid of your headache. It is good to rest, and to drink a lot of water, too. A doctor once told me, "With the right medicine, a cold will last for seven days. With no medicine, it will go on for a whole week!"
Where does our medicine come from? A long time ago, people understood that some plants made them feel better. They ate the leaves, the roots , the fruit or the seeds of plants. For example, the juice of lemons (柠檬) makes a sore throat feel better. In modern times, scientists have looked at these plants, and found out which chemicals (化学药品) are in them. Many of our medicines today are made from those chemicals. There are some diseases that we can't cure yet. And nobody has found a cure for old age. But because of modern medicines, the average (平均的) person now lives longer than their grandparents.

The common cold is the world's most widespread illness, which is a plague that man receives.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions, explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War, soldiers who spent long periods in the trenches, cold and wet, seldom caught colds.
In the Second World War, prisoners at Auschwitz concentration camp, naked and starved, were astonished to find that they seldom had colds.
At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in a room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If then, cold and wet have nothing to do with catching colds, why are they more frequent in winter? Despite the most hard research, no one has yet found out the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and that makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain-killers such as aspirin, but all that they do is to relieve the symptoms.
1.The writer offered ___ examples to support his argument.
A. 4 B. 5
C. 6 D. 3
2.Arctic explorers may catch colds when___.
A. they are working in the isolated Arctic regions
B. they are writing reports in terribly cold weather
C. they are free from work in the isolated Arctic regions
D. they are coming into touch again with the outside world
3.Volunteers taking part in the experiments in the Common Cold Research Unit___.
A. suffered a lot B. never caught colds
C. often caught colds D. became very strong
4.The passage mainly discusses___.
A. the experiments on the common cold
B. the fallacy about the common cold
C. the reason and the way people catch colds
D. the continued spread of common colds

And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches (战壕) cold and wet, showed no increased tendency to catch colds. In the Second World War prisoners at the notorious Auschwitz concentration camp (奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds.
At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be dipped with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.

AIDS may be one of the most undesirable diseases in the world. Luckily, there is now hope for AIDS patients.
According to a recent paper published in the New England Journal of Medicine, Chinese scientists have successfully used CRISPR technology - a method of gene editing - to treat a patient with HIV. While it may not have cured the patient fully, it still represents a huge step forward in fighting the disease.
The patient was a 27-year-old Chinese man who was diagnosed with both AIDS and acute lymphoblastic leukemia (急性淋巴细胞白血病), a type of blood cancer. Despite his hopeless situation, doctors offered him a glimmer of hope: a bone marrow (骨髓) transplant to treat his cancer and an experimental treatment for his HIV.
They used this opportunity to edit the DNA in bone marrow stem cells from a donor before transplanting the cells into the patient.
Specifically, the treatment involved using the gene-editing tool CRISPR-Cas9 to delete a gene known as CCR5, which encodes a protein that HIV uses to get inside human cells. Without the gene, HIV is unable to infiltrate cells.
Talking about the gene, lead scientist Deng Hongkui told CNN, “After being edited, the cells - and the blood cells they produce - have the ability to resist HIV infection.”
Nineteen months after the treatment, the patient’s leukemia was in complete remission (缓解) and donor cells without CCR5 remained, according to the research paper.
Though the transplant did not cure the man’s HIV, it still showed the effectiveness of gene-editing technology, as there was no indication of any unintended genetic alterations - a major concern with past gene therapy experiments.
Amesh Adalja, a senior scholar at the Johns Hopkins Centre for Health Security in the United States, who was not involved in the study, praised the treatment.
“They did a very innovative experiment. It was safe,” he told Live Science. “It should be viewed as a success.”
Deng believes gene-editing technology could “bring a new dawn” to blood-related diseases such as AIDS and sickle cell anemia (镰刀形细胞性贫血).
“Thanks to this new technology, the goal of a functional cure for AIDS is getting closer and closer,” he said.
1.The technology of CRISPR is to ___________.
A.transplant cells B.encode genes
C.remove proteins D.produce cells
2.What was the result of the treatment?
A.CCR5 and other genes in the patient’s cells were changed.
B.The number of cells infected by HIV decreased.
C.Some of the patient’s blood cells could resist HIV infection.
D.HIV no longer existed in the patient’s cells.
3.What do we know about the experiment?
A.It provided an innovative way to cure AIDS patients.
B.It pointed out the problems of gene therapy.
C.It could offer a safe treatment for blood-related diseases.
D.It’s the first experiment to use gene-editing technology to treat AIDS.

Heart disease is one of the major killers in the world today. Many who suffer from it must have heart transplants. However, it’s difficult to get a suitable heart donation, and even if a patient survives the wait, his or her body often rejects 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, chambers 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. And, although it can contract like a muscle, it cannot pump out blood like a real one. At present, the heart prototype 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 into human heart tissue with stem cell 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 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 do scientists have to do further research before fitting the 3D-printed heart into the body?
A.Because the heart is incomplete.
B.Because the heart can’t pump out blood.
C.Because the heart is an airplane that can’t fly.
D.Because the heart can’t contract like a muscle.
2.What can we infer from the last two paragraphs?
A.The needed heart will be printed to meet every patient’s need.
B.The 3D printing of organs will be an unusual medical practice.
C.Dvir has a negative attitude towards the future of organ printers.
D.Patients will need medicines to stop their rejection for their heart transplant.
3.What can serve as the best title for the passage?
A.Organ printers in the hospitals.
B.How to get a suitable heart donation.
C.Heart disease: one of the major killers.
D.A 3D-printed heart: new hope for heart disease sufferers.

Most people are aware of what the adoption process is because it has become rather common in our society. Adoption is where a child is legally placed with guardians (监护人) or parents (or perhaps a single parent) other than the birth mother or father. Once an adoption is finalized, all parental rights are turned over to the adoptive parents and there is no legal difference between adoptive parents and natural birth parents. There are generally two types of adoption, which are closed adoption and open adoption.
When an adopted person has access to his or her adoption file and original records, it is referred to as an open adoption. The term is also used to describe any contact that may be between the adoptive family, the birth parents, and the adopted child. The level of openness can change greatly in such contact depending on each individual relationship. There can be indirect contact between the natural birth parents and the child through the form of letters and photographs, or there can be actual physical contact.
A semi-open adoption is where the birth parents may have contact with the adoptive parents before the birth of the child, either once or several times. After the birth there is no more contact. A semi-open adoption may remain as it is or it can become either open or closed.
A closed adoption is where only the medical and historical information about the biological parents is given to the adoptive family. Typically, the birth and adoptive parents do not know each other’s identities. The record of the birth parents is kept sealed (密封). A closed adoption is usually only effective in the adoption of babies. The adoption of an older child who already knows his or her birth parents cannot be kept closed.
1.How many adoption types are mentioned in the passage?
A. 2. B. 3. C. 4. D. 5.
2.Which of the following statements is TRUE about the closed adoption?
A. The birth parents may have indirect contact with the adoptive parents.
B. The biological parents may often go to see their birth child.
C. No information about the biological parents is given to the adoptive parents.
D. Generally speaking, the adoptive parents do not know the birth parents’ identities.
3.Suppose someone adopts a child and his biological parents often get contact with the child by telephone. We can call this adoption _____.
A. a closed adoption B. an open adoption
C. a semi-open adoption D. a semi-closed adoption
4.From the passage, we know adoption is _____.
A. where a child is brought up by the government
B. where a child is legally sent abroad by the birth parents
C. where a child is legally placed with adoptive parents
D. where a child is sent to live with the children whose parents have died
