2、ed was Covid- 19.Covid-19 is caused by a new strain of coronavirus. Once entering the body, the virus multiplies inside the cell quickly and infects neighbouring cells. Common symptoms can include fever, tiredness, a dry cough, a headache, loss of taste or smell. However, in some cases, the virus ca

3、uses the bodys own immune system to overreact, resulting in the body killing its own healthy cells. Consequently, the disease can become worse, causing damage to the bodys organs and tissues.Covid-19 is a highly infectious disease that can be transmitted easily and swiftly from person to person. Thi

They can also catch Covid-19 by touching a surface or an object contaminated with the virus, and then touching their own mouth, nose or eyes. Research shows that there are certain settings that allow

5、the virus to spread more easily. For instance, it favours cool, dry conditions and crowded indoor spaces with poor ventilation. What makes this disease even more dangerous is that infected people who show no symptoms may become unknowing carriers and spreaders of the virus.In early 2020, the threat

6、posed by Covid-19 came to be fully recognized on a global scale. It spread rapidly across the world, affecting millions of people. More dangerously, new and even more infectious variants of the virus, such as the Delta and Omicron variants, gradually began to evolve in various parts of the world, pr

In the darkest days when Covid-19 was doing its worst, the human spirit shone at its brightest.While the fight against Covid-19 is a global effort, there are preventive measures that everyone can take to help contr

12、 or have reason to believe that you have been exposed to the virus.

We need to support each other so that we can march confidently, arm in arm, into a better and more secure future.Extended readingSay no to drugsGood morning, everyo

14、ne. As a police officer who has spent many years working in the front line of the fight against drugs, I have witnessed, all too often, the destructive impact that drugs can have on individuals, families and the wider community. I have seen how drugs can destroy peoples physical and mental well-bein

15、g and ruin young lives before they even begin. I have seen how families are torn apart after a family member has become addicted to drugs. I have also seen how tirelessly the forces of law and order work together in fighting against drugs. I will not exaggerate the scale of the problem, as the facts

16、 speak for themselves. According to the 2021 World Drug Report, it is estimated that around 275 million people used drugs worldwide and over 36 million people suffered from drug use disorders in the last year. These shocking figures indicate that drug abuse is a very serious global problem. Therefor

17、e, it is everyones responsibility to say no to drugs.Drug abuse hurts an individual drug user both physically and mentally. The most serious health conditions associated with drug abuse include heart problems, respiratory problems, kidney failure, liver damage and a weakened immune system, increasin

18、g the risk of illness and infection. Moreover, drugs interfere with a person5s ability to make sensible decisions. Consequently, people under the influence of drugs are no longer in control of their own mind and likely to put themselves or others in great danger. They also suffer from memory loss an

19、d mood disorders like depression or anxiety.Apart from its harm to individuals, drug abuse also destroys families and impacts society as a whole. Drug users sometimes lie and steal to fuel their habit, while ignoring the responsibilities they have to their families. This can lead to not only financi

20、al hardship but also the breakdown of once strong family relationships and the loss of stability within the family. The impact drug abuse has on society is also enormous. Under the influence of drugs, drug users may exhibit violent behaviour and sometimes even commit criminal acts, threatening publi

21、c safety. They are willing to do anything to get their hands on drugs. Also, because drug users need a regular supply of drugs, the criminal underworld quickly develops, eating away at the fabric of society.Knowing the serious damage that can be caused through the use of drugs, you may be asking you

22、rself: why would anybody be foolish enough to start taking drugs? There is no simple answer to this question, but there are well-identified risk factors for drug abuse. Some people experiment with drugs simply out of curiosity, some regard drug use as an escape from the stresses of everyday life, an

23、d others start to use drugs just because people around them are drug users.Fortunately, there are things you can do to protect yourself from drug use. First of all, drug education is of vital importance. You should learn more about drugs, especially new designer drugs, which are incredibly dangerous

24、. The more you know about the terrible consequences of taking drugs, the more likely you are to stay away from them. Secondly, you need to choose where you go and who you spend time with very carefully. Make sure you surround yourself with friends who you can really count on and turn to for support.

25、 Last but not least, should you ever come under pressure to use drugs, you must immediately seek assistance from an adult who you look up to, such as a family member, a teacher or a doctor.In conclusion, I hope my message is clear-say no to any kind of drug. The most effective way to avoid all the problems caused by the use of drugs is not to use them in the first place.
