Lisinopril

What is lisinopril? Lisinopril is a medicine to treat high blood pressure. This medicine is only available on prescription. It comes as tablets. It also comes as a liquid for people who find it hard to swallow tablets, but this has to be ordered specially by your doctor.

Important information

To make sure lisinopril is safe for you, tell your doctor if you have:

● heart, liver or kidney problems

● diabetes (糖尿病)

● higher levels of potassium (钾) in your blood

Women who are pregnant can’t take the medicine. It could harm the unborn baby.

What if I forget to take it?

If you miss a dose of lisinopril, take it as soon as you remember. If you don’t remember until the following day, skip the missed dose. Do not take a double dose to make up for a forgotten one. If you forget doses often, it may help to set an alarm to remind you.

What should I avoid while taking lisinopril?

Over the past couple of days,on our local Freecycle page there have been a lot of wanted posts,all from the same person, basically asking for everything you’d need to set up a house from scratch.One of the things they asked for was a queen-sized bed. At that time we just happened to have an extra one, so I messaged them. They immediately came in the afternoon. The people who came, two ladies and a man, are actually friends of another woman named Jenny who owned a young boy. This woman has escaped from a dangerous, violent relationship and these friends of hers are helping her and her son start over again, with everything from furniture to toothbrushes on their list of needs.

While they were here, I also gave them one of our spare bookcase and some coffee cups.

I even asked them to keep in touch in case they needed anything else —I have a way of connecting people with things. I offered the woman a cupboard we had as well; her friends just needed to see if there was a place and /or a need for it in their friend's new home.

I was so excited to meet those loving people, who were obviously willing to help their friend. It was clear how protective they felt of this woman and her boy, how much they love her and wanted her to have a happy and safe life, and to spend even a few minutes with people like that is an experience I’l l remember for a long, long time.

A quick thank-you to all who have sent more donations over the last couple of days, as well as lovely messages of thanks and blessings. Sometimes it’s hard to keep up with it all,but it’s a problem I’m happy to have.

Dr. John Wilkins was a natural philosopher who lived from 1614 until 1672. He was crazy about getting to the moon and meeting the people who surely lived there. Wilkins believed that anything as Earth-like as the moon must have been created by God for living beings, and he was determined to meet them — despite the fact that he was three centuries ahead of his time.

In the 1600s, the scientific understanding of gravity and outer space was limited. Wilkins believed, like many 17th-century scientists, that there was no difference between the atmosphere of Earth and the conditions in space, and that Earth’s pull was due to magnetism ( 磁力). It was only reasonable, then, that Wilkins believed a two-wheeled horse-drawn battle car with wings with enough speed could lift high enough off the ground to break free of Earth’s magnetic pull and reach the moon.

Then Wilkins moved on to more pressing issues with his remarkable ability to think of new ideas: How would travelers feed themselves during the journey? He theorized that the main cause of hunger was simply the act of working against gravity, so getting to the moon without being burdened by it would be able to be realized. There was some knowledge at that time about the fact that air gets thinner and colder the higher up you go, but he had a fix for that too, “moistened sponges (湿润的海绵) might help us against its thinnes s” .

By studying the way in which birds fly, which also happened to be part of the studies that led to planes and rockets centuries later, Wilkins put his theory to the test with the help of a colleague, Robert Hooke. Neither of the two ever recorded their attempts, but it’s somewhat safe to say that it didn’t work out. Hooke himself may have been the reason he gave up hope, in fact, since he was part of the team that discovered space was a place without oxygen.

28. What do we know about Dr. John Wilkins?

A. He dreamed of landing on the moon.

B. He wrote about people living on the moon.

C. He urged the public to know more about space.

D. He had a rich knowledge of space in the 1670s.

29. Which of the following might Wilkins agree with?

A. The air on the moon is not fit for human beings.

B. People don’t need to eat things on the moon.

C. Earth’s magnetism can be changed easily.

D. Oxygen doesn’t exist in outer space.

30. What can be concluded from Paragraphs 2 & 3?

A. Wilkins had prepared a lot in theory.

B. Wilkins was ready for his moon-landing.

C. Wilkins made a great contribution to philosophy.

D. Wilkins was the greatest natural philosopher in history.

31. What is the author’s purpose in writing the text?

A. To honor a great scientist.

B. To encourage studies on outer space.

C. To introduce an early attempt of moon-landing.

D. To inform people of the knowledge about the universe.

D

Breathing dirty air comes at a high price. Air pollution lowers the average life spans (寿命) by a year worldwide and in more polluted parts of Asia and Africa, dirty air shortens lives up to twice that much. Scientists shared their new findings in Environmental Science & Technology Letters. The study used data gathered in 2016 as part of a project known as the Global Burden of Disease and was the first major country-by-country look at the connection between the length of life and what’s known as fine PM.

Air pollution has been linked to many health problems. Most earlier studies had looked at how tiny air pollutants affected rates of illness or death. Joshua Apte is an environmental scientist at the University of Texas at Austin. By looking at life expectancy (预期寿命), his team had hoped to make the threat easier to understand. PM2.5 is what scientists call tiny particles (颗粒) of pollution in the air. Higher levels of PM2.5 can cause health problems and cut months, if not years, from the average length of life. This analysis shows how pollution affects life expectancy in different parts of the world.

The World Health Organization (WHO) recommends limiting PM2.5 to 10 micrograms per cubic meter of air. Apte’s group calculated how holding pollution to this low level would help people. In countries with very dirty air, meeting this standard would lengthen people’s lives. However, in countries whose air already meets this standard, the study shows no gain in life expectancy. In other words, meeting the WHO standard won’t reduce health costs resulting from dirty air because even below 10 micrograms per cubic meter, pollution still causes serious risks. Meanwhile, the scientists compared how other threats including smoking and cancer shorten the length of life across the globe.

32. What is special about the study?

A. It won recognition from a professional journal.

B. It discussed health problems caused by air pollution.

C. It gathered lots of data for the Global Burden of Disease.

D.

It analyzed the link between life spans and PM by country.

33. What is Joshua Apte’s team trying to do?

A. Help people better understand air pollution.

B. Study life expectancy in different countries.

C. Know how small air pollutants affect health.

D. Deal with different kinds of health problems.

34. What will happen if a country limits PM2.5 to 10 micrograms per cubic meter of air?

A. People’s life spans will surely increase.

B. It will get strong support from the WHO.

C. People’s health may not be much improved.

D. It will guarantee people clean air.

35. What might be discussed in the following paragraphs?

A. How cleaning up the air can lengthen lives.

B. How air pollution shortens lives by country.

C. How other threats shorten life expectancy.

D. How all the countries deal with severe pollution.

项。

Everyone is aware that taking good care of our bodies can prevent many medical problems from occurring later. However, we often have less awareness of preventative actions we should take to help with mental health problems. While our mental health may be fine right now, many of us will struggle at some point. 36 It’s impossible to get through life without challenges, but our mental health prevention habits can help us get through difficult times. 37

Keep active. The more active you physically, mentally and socially are, the higher the level of your mental wellness is likely to be. So go for walks and learn something new. There are many other ways to be active. 38

Be connected. Regular involvement in social activities with supportive friends and family improves your ability to handle disappointments, and everything else life throws at you. 39 But you can be involved in any manner; even volunteering for an organization can help you be more social.

40 The nature of these activities varies widely from person to person. The key is to identify what gives your life meaning. Volunteering, coaching, teaching, etc. all can contribute to increasing your sense of confidence and satisfaction with life. Many activities can address more than one. The key is to make a plan and stick with it. If you are already struggling, begin to practice these ways to help your recovery.

A. Here are three practical steps.

B. However, good mental health is important.

C. Stresses, disappointments and disasters happen.

D.

Overcome li fe’s challenges before they happen. E.

Be committed to activities that give life meaning.

F. The key is to find what keeps you motivated and interested.

G. This can be difficult when you move to a new town or as you get older.

遭到了很多人的批评。《小时代》中的物质化的生活态度和方式,连对之持宽容态度的王安忆也觉得这种以物判人的奇怪现象,可能会被 将来的文学史注意到。面对咄咄逼人的消费写作 ....,王安忆有意隐藏了自己的价值判断,有一些各行其道、互不干涉的意味。但是,从另外一个维度上讲,王安忆的《众声喧哗》和郭敬明的《小时代》,一个是纯文学的路数,一个是类型写作的路数,却从两个不同的方向包抄过来,共同指向了今天的文化现实———转型之中国正进入了一个众声喧哗的小时代。 ②从艺术水准来看,《小时代》确实乏善可陈,充其量是一部类型片,但是《小时代》的出现似乎宣示了一个时代预言:我们正进入一个奠基于个人主义之上的无边的消费主义、精致的物质主义、价值的虚无主义的小时代。不仅如此,随着微信、微博在青年人生活中的流行,并日益成为不可替代的通讯工具乃至成为一种生活方式,一个个体化、群落化、亚风格化的小时代、微时代已经呈现在我们的面前。 ③小时代、微时代的到来,与崇高、理想等有关的那些坚固的东西也许真的从此烟消云散了。对大时代的每一次回望,都是一次告别的聚会。这个小时代的到来,对小说的意义在于,在充满着复杂的流动性的转型中国,小说家对时代的整体性把握将越来越不可能,史诗这种传统的农耕文明的写作方式将有可能被封入历史的库房中,任何想从整体上对这个时代命名的企图和冲动将不得不最终沦为可笑的堂·吉诃德。
