Influenza is an infection caused by flu viruses travelling through the air and entering the body through the nose or mouth. From October 2018 to early May 2019, up to 61,200 people died due to flu complications, while up to 647,000 people were hospitalized, according to the Centers for Disease Control and Prevention. Despite similar symptoms, a cold is milder than the flu while flu symptoms develop more suddenly and severely and can impact your body above and below the neck. 1.
Several factors can lead to Influenza. 2. You can catch the flu, breathing in these droplets, or touching objects such as doorknobs or keyboards that are contaminated with the virus and then touching your nose, or mouth. People under 4, or above 65 or with a weakened immune system are at greater risk of catching the flu.
Treatment without delay plays a dominant role. If you promptly see your doctor upon noticing symptoms, he or she may give you an antiviral drug, oseltamivir. 3.“The best way to treat the flu is to rest, drink fluids and use any other remedies that best relieve your symptoms such as pain reliever for headaches and achy muscles.” says a professor of infectious diseases at Northwestern Memorial Hospital.
Prevention is better than defense.4. Experts widely agree that the single best way is to get the vaccine (疫苗) each year, which is appropriate for anyone 6 months and older. 5. Moreover, practicing good hygiene can prevent flu germs from spreading. Highly recommended are washing your hands, coughing or sneezing into a tissue, avoiding touching your nose and mouth, cleaning surfaces and objects like keyboards and telephones and avoiding crowded areas.
A.Approaches to flu vary from expert to expert.
B.You can escape catching influenza with some common-sense health practices.
C.When someone with the flu coughs or sneezes, droplets carrying the virus enter the air.
D.These can include fever, achy muscles, sore throat, cough, headache, chills, fatigue or vomiting.
E.The flu shot protects against the most common three or four flu viruses research indicates that year.
F.If taken within two days, the medicine can lessen symptoms and shorten the length of time you are sick by about a day.
G.To determine if you have the flu or a cold, your doctor will do a physical exam, ask about your symptoms, and possibly do a lab test.
On Tuesday, China announced it had grown the first ever plants on the moon, days after landing on the moon’s “far side” Von Karman crater. The cotton seed sprouts (新芽) seemed to have withstood the tough lunar conditions: freezing temperatures, lower gravity levels, and radiation.
But by Thursday, the new cotton seed sprouts had dead already, according to Liu Hanlong, the experiment leader, in a government press conference statement.
After Chang’e-4 landed on the far side of the moon earlier this month, the probe (探测器) was sent a command to remotely water the plants and start the growing process. A tube directed natural light on the surface of the moon into the small container to allow the plants to grow. The probe entered a sleep mode on Sunday, the first lunar night after the probe’s landing.
Professor Xie Gengxin, professor at Chongqing University and chief designer of the experiment, told CNN that it ended after nine days when the control team shut down the power. Xie said temperatures inside the biosphere had grown too abnormal and reached extremes that would likely kill all life, including the seeds and eggs during the lunar night. Xie didn’t confirm why temperatures had risen to levels unbearable for the plants in spite of the measures taken by the research team.
Even though the experiment was quickly terminated, Xie considered it a success. The cotton were the only seeds to sprout, however, and despite many assumptions about the future possibility of moon clothes, the cotton plant’s main purpose this time was to give researchers the valuable data on how to cultivate life in the moon’s tough conditions. The eventual ability to grow plants on the moon could prove useful for long-term space missions, like a trip to Mars. Astronauts could theoretically harvest their own food in space, avoiding the need to return to Earth to resupply.
Aside from the apparent failure of the biological or plant experiment, the rest of China’s mission to the far side of the moon appeared on track as of Thursday. The historic mission is intended to accomplish a range of tasks, including conducting the first lunar low-frequency radio astronomy experiment and exploring whether there is water at the moon’s poles.
Chang’e-4 is the latest step in China’s robotic lunar-exploration program, named after a moon goddess in Chinese mythology. China plans to launch the Chang’e-5 sample-return mission sometime this year.

When a friend does something less-than-kind like breaking something precious, embarrassing or excluding kids, it’s understandable that children feel hurt, betrayed, angry or bitter. Some may get even with the friend by doing something worse, which, however, only worsens conflicts. Children may feel caught in the tension between wanting to keep the friend and feeling unable to let go of bitterness about a serious offense.
Reine C. van der Wai and colleagues define forgiveness as the process of controlling the automatic negative thoughts and feelings that spring up when someone upsets us and instead treating that person with kindness. They argue that forgiveness is an essential skill for maintaining long-term friendships.
Parents can play a dominant role in teaching children about forgiveness. Children watch how adults in their lives respond when someone does something unkind. Do they let it go or complain to others or speak directly to the person involved? How long does it take them to get over being mad and how? Sometimes parents instruct children directly about how to react to friends’ mistakes, promoting responses ranging from “Don’t let him walk all over you and fight back!” to “He didn’t mean it.” or “Everyone makes mistakes, depending on the situation and the family values.”
There’s a delicate balance that children need to strike when it comes to forgiveness. On the one hand, passively tolerating and excusing on-going mean behavior definitely isn't healthy. Research shows that long term, repeatedly forgiving people who don’t mend their ways eats away at self-respect. On the other hand, kids need to understand that no one is perfect, so generously and sympathetically forgiving a well-meaning friend is a caring thing to do.
Here are some guidelines that might help your child figure out when it’s time to let it go and forgive someone. If it only happened one time, and it probably won’t happen again, let it go. If your friend didn’t do it on purpose, let it go. If it wasn’t that bad, let it go. If your friend is really sorry, let it go. If it was just a mistake and the friend is usually kind, let it go. If it happened more than a month ago, definitely let it go.
Holding onto hatred is emotionally costly. Sometimes, forgiveness is the right thing to do, not because the other person deserves it, but because we deserve not to be weighed down with bitterness.
1.When a friend does something unfriendly, what is NOT the possible response of the children according to Paragraph 1?
A.They are in a dilemma.
B.They intensify the contradiction.
C.They are upset, disappointed or annoyed.
D.They consider the offence understandable.
2.Children are educated about forgiveness in a family by _______.
A.taking the family values into account
B.speaking directly to the related person
C.observing parents’ reactions to a person doing something unpleasant
D.following the instructions like ignoring a friend or forgiving the mistakes
3.Which of the following is NOT right according to the passage?
A.If your friend didn’t do it deliberately, let it go.
B.Pursuing perfectionism contributes to forgiving a well-intentioned person.
C.Continuously forgiving people who fail to reform will lead to lack of confidence.
D.On some occasions, forgiving the other person is psychologically beneficial for us.
4.What is the attitude of Reine C. van der Wai and colleagues towards forgiveness?
A.Favorable. B.Neutral.
C.Pessimistic. D.Critical.
A person once told me that a quick way to know if you are in the right job is to count the number of good and bad days that you have at your current job. If the good days outweigh the bad days by a long shot, then you are probably in the right place.
While I like that as a quick test, it does not get at the heart of the matter. Is this the right job for me now and in the future? I think it takes time, introspection (内省) and willingness to ask yourself difficult questions to know if you are in the right job.
Here are a few suggested questions that can help you evaluate whether your current job is fit for you. How motivated are you to do the work every day? Are you passionate about the work? Do you feel you can make an impact? Are you learning and growing? Is the work challenging? Do you desire to take on more responsibility or be your manager one day? Do you enjoy working with the people on your team and at your company? Are you in line with the values at the company?
After you go through this exercise of self-reflection, it can be helpful to check in with an advisor or someone that knows you well like a friend or family member. They can offer different perspectives or help remove a blind spot for you.
I have had a few notable experiences where someone has shared feedback that suggested I was not in the right job and should consider other options. It caused an overwhelming sense of loss at first because I was quite comfortable in my role (or at least I thought I was). However, it was several days before I realized it was the best feedback that I had ever gotten because it led me to the next opportunity that was even better than the current one. It turned out that when I was doing my self-reflection and answering the questions above, I was not being honest with myself. Had I only relied on my own thinking, I would have not obtained the opportunities that came next.
1.What question CAN’T help you assess whether you are enjoying the work itself and accomplishing something?
A.Are you passionate about the work?
B.Do you feel you can make an impact?
C.Are you in line with the values at the company?
D.How motivated are you to do the work every day?
2.It can be helpful to tell an advisor or people acquainted with you after you finish 8 important questions of self-reflection because _________.
A.they get to the point of the matter
B.they are resourceful with numerous experiences
C.they can encourage you to figure out the number of sunny days and rainy days
D.they can view things from different angles and remind you of things likely to be neglected
3.What can we infer from the last paragraph?
A.It’s wise to answer questions right away.
B.Prior to the shared feedback, the author received the best suggestion.
C.The author was satisfied initially when others suggested considering other choices.
D.Having considered others’ shared feedback, the author had a better opportunity.
4.Which of the following best describes the author?
A.Open-minded. B.Stubborn.
C.Loyal. D.Knowledgeable.
