Life is full of challenges. Some people seem to meet every challenge with confidence, while others struggle to overcome them. Here are some ways to better meet your personal challenges, whatever they may be.
Do not undervalue the power of being present. If you make a practice of facing your challenges - even in failure - with full presence and awareness, 1.. You can ask yourself questions that help you better understand the problem.
2.. Others can help you arrive at your own understanding, but no one ever solves your problems for you. Even in circumstances where someone else is acting as a partner, only you can decide for yourself how you will process the situation. The longer you spend searching for guidance outside of yourself, the longer you spend ignoring the problem. Assess the situation, your resources, and your abilities, and then act. 3..
It is important to know yourself. There is a reason why certain challenges seem hard for you while easy for others. 4.. It's all about consciousness. Those who face challenging tasks have found a way to avoid seeing those activities as challenges.
Challenges are opportunities to grow. That growth takes place out of potentiality, your potentiality, which is tremendous and highly active in every moment of life. Come to know yourself as that. Challenges can guide you to awareness.
Pay little attention to the outcome. 5.. Once you focus on what you're actually doing, instead of the result, the most upsetting part starts to disappear.
A.Look to yourself for the solution
B.Don't trouble yourself with questions
C.It's not because they are better than you
D.you may have a sense of being stuck anywhere
E.you will find most challenges are not challenges at all
F.The sooner you take up the challenge, the quicker it stops being a problem
G.Worrying about the potential outcome is often what turns a hill into a mountain
At this time of year, with the nights closing in spring can seem very far away. For hill farmers, the call of the Eurasian curlew(白腰杓鹬) will be a reminder that winter is nearly over for another year. However, there are some parts of the UK and Ireland where farmers are no longer hearing their call.
Around early March, the curlew moves inland to breed, remaining obviously faithful to the sites where they have bred before. Their preferred nesting sites are rough grassland and moorland , which provide a mix of both open areas to feed and low bushes in which to hide their nests.
So why should we be concerned? The curlew is in serious trouble. The number of breeding curlews across the UK has dropped by 48% since the mid-90s. There are less than 150 pairs remaining in Ireland, down from 3, 750—4, 000 pairs in the late '80s, which is a disastrous decline of 96%. In southern and eastern England, recent surveys have shown there are fewer than 300 pairs remaining. Consequently, the curlews in Ireland and southern and eastern England are thought to be at the risk of upcoming extinction, while declines in the UK are also of serious concern. This is a potential disaster, not only for the UK and Ireland, but also the world as we are home to up to 27% of the global breeding population。.
What is driving the decline? What seems to be the problem? Firstly, the curlew is long-lived and should be able to keep stable numbers if each pair raises one baby bird every couple of months. Unfortunately, in many areas their breeding success rate is much lower. The main cause of this lack of production is loss of suitable living places due to land use change, such as agricultural practices and forestry. Secondly, their enemies, including foxes and crows, have multiplied rapidly over the last few decades
The challenge of responding to the problem is huge particularly as the curlews widely spread all over the lands. We cannot lose the curlew so how can we make a difference?
1.What do the underlined words in paragraph 1 probably mean?
A.Spring hasn't come as expected.
B.Spring comes really later than usual.
C.Farmers are looking forward to the coming of spring.
D.Farmers mistake the call of the curlew for the arrival of spring.
2.How does the author support his idea in paragraph 3?
A.By describing a process. B.By making comparisons.
C.By listing numbers. D.By analyzing causes.
3.What is mainly talked about in paragraph 4?
A.The curlew is facing threats. B.The curlew can't give birth to baby birds.
C.The number of curlews is dropping quickly. D.The curlew has a low breeding success rate.
4.What will the author most probably discuss next?
A.done on the curlew.
B.Efforts made to save the curlew.
C.Reasons for the decline of the curlew's population.
D.Concern from people about the future of the curlew.
Denmark is only about half the size of South Carolina, but it produces more of its electricity from wind than any other country in the world. That's not because it's a country with particularly strong wind; it has pretty ordinary wind speeds. The reason why the Danes now get 47% of their electricity from wind, with more to come, comes down to a combination of history and policy.
First, the history: Paul la Cour was a scientist and inventor who experimented with and built early wind power machines at the start of the 20th century. So it's not surprising that Denmark spent money building wind power plants early, beginning at a national level in the 1970s. In the 1980s, because of a strong movement against nuclear （原子核的）power plants, Denmark increased production before many other countries were even considering it.
Denmark has also had important government support for wind-energy projects, as well as support from the country 's technology-focused universities. Even back in 2002, the country was taking climate change warnings seriously, successfully cutting greenhouse gas emissions （排放）by 20%.
Some of the world's largest companies—including Vestas, which builds turbines （(涡轮）， and Orsted, which specializes in offshore wind projects—are Danish. European countries are global leaders in using wind power but Denmark is far in front of its nearest competitor Ireland, which sourced 28% of its power from wind in 2018 according to industry group Wind Europe.
At the end of 2019, lawmakers in Denmark set a new goal to reduce greenhouse gas emissions by 70% by 2030 and increase the share of electricity sourced from renewable power to 100%.
1.What do we know about Denmark from Paragraph 1?
A.It produces more than half of its electricity from wind.
B.It makes the most of its wind to produce electricity .
C.It is the most environmentally friendly country.
D.It is a country with rich wind resources.
2.What is the key message of Paragraph 2?
A.Denmark started making use of wind power very early .
B.Paul la Cour built wind power plants in the whole country.
C.Nuclear power plants produce most electricity in Denmark.
D.Denmark taught other countries to build wind power plants.
3.Some large companies are mentioned to show that Denmark .
A.has an influential role on the world stage
B.has many technology-focused companies
C.is the head office of many large companies
D.is the world's leading wind power country
4.In which part of a newspaper can you read the text?
A.History. B.Lifestyle. C.Environment. D.Society.
