China to introduce 'forest chief' scheme nationwide

Trees cover a hillside in Wuqi, Shaanxi province, the first county involved in the Conversion of Cropland to Forest and Grassland Program, in last June.
BEIJING -- China has issued a guideline to implement a "forest chief" scheme nationwide amid the country's continuous efforts to protect forests and grasslands.
It was issued by the general offices of the Communist Party of China Central Committee and the State Council and urged that the "forest chief" scheme will be rolled out nationwide by June 2022.
"General forest chiefs" should be appointed in all provincial-level regions, said the guideline. It clarified all levels of forest chiefs' responsibilities in protecting forest and grassland resources.
Under the scheme, China will strengthen ecological protection and restoration of forests and grasslands, promote large-scale afforestation, and enhance monitoring and supervision for forest and grassland resources by utilizing modern information technologies.
Efforts will also encourage the prevention and control of harmful pests and plant diseases, as well as natural disasters such as fires.
China started trials of the "forest chief" scheme in 2017, and so far up to 23 provincial regions, including Anhui, Jiangxi and Chongqing, have already carried out the trial program, providing the foundation for nationwide implementation.
"Nationwide implementation of the 'forest chief' scheme is a key step in enhancing local responsibilities in ecological protection," said Guan Zhiou, head of the National Forestry and Grassland Administration.
Indicators measuring the performance of "forest chiefs" will include forest coverage, forest stock volume, comprehensive vegetation coverage of grassland and the area of desertified land restored, while specific targets will be tailored in accordance with local conditions, according to Guan.
He said he believes nationwide implementation of the scheme will help pool resources and strength to enhance the protection of China's forest and grassland resources.

1. (教材P2) With an area of around 5.5 million square kilometres, the Amazon rainforest is more than half the size of China. 亚马孙雨林占地约550万平方公里，是中国面积的一半以上。
【句式剖析】句中的“is more than half the size of”为倍数表达法。
【考点提炼】倍数表达法
常见的倍数表达法有以下几种：（前“倍”）
(1) A is＋倍数＋as＋形容词/副词原级＋as B
(2) A is＋倍数＋形容词/副词比较级＋than B
(3) A is＋倍数＋the＋计量名词＋of B
(4) 倍数＋what从句
注意 (1)注意倍数的位置；倍数部分也可用分数、百分数代替。
(2)表达倍数时，一倍常用once，两倍常用twice或double，三倍及三倍以上常用“基数词+times”。
如：语法填空
1. It’s said that the power plant is now twice as large as what it was.
2. Sound travels about four times faster(fast) in water than in air.
3. Nowadays the number of the athletes in the National Games is twice what it was ten years ago.

2. (教材P3) Above that is the mass of leaf litter on the dark forest floor. 在那之上，大量落叶层覆盖着昏暗的雨林地面。
【句式剖析】本句为完全倒装句。因作表语的介词短语也表方位或地点Above that置于句子开头，整句进行了全部倒装。正常语序为：“The mass of leaf litter on the dark forest floor is above that.”。
【考点提炼】完全倒装
完全倒装，即将句中的谓语动词全部置于主语之前，此结构通常只用于一般现在时和一般过去时，不用于进行或将来时。使用完全倒装的情况有：
①当主语是名词时，将表示地点或方位的副词、介词短语置于句首，如here, there, up, down, in, away, off, out, in the room, on the wall等（如果主语为人称代词，则不需倒装）；
②such置于句首时，其后的句子要用完全倒装；
③表语（分词、不定式、形容词、介词短语等）前置，句子用全部倒装。
如：(1)Into the dark apartment walked David, who was quite surprised when everyone shouted Happy Birthday.
大卫走进了黑暗的房间，当大家喊生日快乐时，他感到很惊讶。
(2)Then came the order to take off. 起飞的命令到了。
(3)Such is(be) our home in the future. 这就是我们未来的家。（此句也可看做因表语前置引起的完全倒装）
(4)Sitting at the back of the classroom were several old teachers. →现在分词、过去分词或不定式置于句首
(5)Gone are the days when my heart was young and happy.
(6)Great was his surprise when he heard the news. 他听到这个消息时大为吃惊。

If you’ll be taking vacation time in the coming year and plan on flying, here are some shopping tips for you. Those who fly first class and don’t care what airline tickets cost are excused from this lesson.
When to buy
If you are shopping for domestic(国内的) flights, check prices on Tuesday afternoons. This is an old tip but still useful because most US carriers continue to release sales on Tuesday morning, and competitors quickly drop their fares to match the better deals.
When to fly
Weekdays continue to be generally cheaper times to fly than weekends for most flights. In the US, the cheapest days are typically Tuesday, Wednesday and Saturday. A good itinerary(行程) for the expensive US spring break travel period is Tuesday to Saturday; it will save you money over weekend-to-weekend travel.
Where to fly
We continue to see good deals to Boston and Denver and more and more nice prices to Chicago, Seattle and Washington, D. C. As for Europe, there have been surprising deals throughout the fall and those will continue into the winter.
Direct vs. connecting flights
Compare the price of direct with connecting flights. Sometimes adding a stop to your route will save you money. An example: an Francisco to Raleigh/Durham: $553 direct, $362 one-stop.
You’d better think twice about the direct flight for San Francisco to Raleigh.
Compare, compare, compare
Stifle the impulse to go to your favorite airline site to purchase tickets without doing any comparison. Example: Let’s say you want to fly from New York to London and figure your favorite US legacy carrier will get you there for the best price. Airline price: $554 round-trip.
However, the comparison site also showed a cheaper flight from the same legacy carrier ($521). See what you’re missing when you fail to compare?
1. When can you possibly find the best price for flights within the US?
A. On Monday morning. B. On Tuesday morning. C. On Tuesday afternoon. D. On Sunday morning.
2. What does the underlined phrase “stifle the impulse” in the last but one paragraph mean?
A. Feel free to do something. B. Hold off on doing something.
C. Get well prepared for something. D. Make quick decision on something.
3. Who is the text intended for?
A. Those who usually choose first class for their flights.
B. Those who want to find suggestions on where to fly.
C. Those who are traveling during the spring break.
D. Those who are looking for the best airline ticket prices.
B
People like to post their selfies(自拍照) on social media. To know more about it, scientists at Syracuse University in New York recently did a research and came up with some surprising findings.
People who post selfies and use editing software to make themselves look better show behavior connected to narcissism(自恋), the researchers said. Makana Chock, a professor from Syracuse University, said because social media is mostly used by people to share unimportant information about their lives, it is a good place for people to “work towards satisfying their own vanity.” Those “likes” under their Facebook selfies make them feel good.
Besides, people who post group selfies show a need for popularity and a need to belong to a group, the research found. Some people feel “peer(同伴) pressure” to post selfies and some follow the popular belief that if there is no picture of an event or experience, it did not really happen. “Anyway, it shouldn’t be seen as negative. People get sense of satisfaction especially when they get likes. And it does no harm,” Chock said.
Other findings from the study include: There are no major differences on how often men and women post selfies and how often they use editing software. But men who post selfies showed more of a need to be seen as popular than women who posted selfies.
Chock said posting selfies on social media is not all that different from what people have done for many years. On trips and special events, our parents and grandparents used cameras instead of phones to take photos. They would bring back photos to show friends and family. You had no choice but to look at them. You probably commented about how nice everyone in the photos looked, especially children and the person showing the photos. They were happy to hear your comments. That was the old way of “clicking like”. On social media, however, people can decide not to look at photos -- even if they click “like”.
4. What is the research mainly about?
A. The ways of making people look better in selfies.
B. The reasons for people posting selfies on social media.
C. The differences between men and women in posting selfies.
D. The connections between posting selfies and mental health.
5. What does the word “vanity” in paragraph 2 probably mean?
A. A deep desire to know about something. B. A special need to be more popular.
C. Too much pride in one’s own appearance. D. Strong determination to improve oneself.
6. What is Chock’s attitude towards selfie posting?
A. Ambiguous. B. Cautious. C. Disapproving. D. Supportive.
7. From the last paragraph, we know that the older generations showed their photos to friends and family ______.
A. to win praise from viewers B. to show off their cameras
C. to improve relationships D. to share good moments

IV. 七选五阅读
It is known to us all that thinking is a good thing. However, some people don't do it enough, while some people overthink everything. If you're an overthinker, it can be exhausting running through all the possibilities of everything. It's not good that the what-ifs run your life and you are trapped. 16 .
Here are some signs that you are an overhinker, even if you don't feel you are.
■ 17
Why didn't the girl look at me? And why did Peter look away so fast? What does it all mean?! When you're an overthinker, you tend to find meaning in the world around you. It's helpful to remind yourself that things mean the meaning you give them.
■ You think more than you do.
Sometimes you think so much that you don't end up doing anything. You weigh the choices, decide which is the best, and compare; it with a new choice. You end up doing nothing. 18
■ You find it difficult to let things go.
When you've invested a lot of time and energy into something, it can be hard to let it go when it isn't working. 19 The more you think about something, the more it can eat away at you.
■ You want to get everything right.
You might be a perfectionist. You always do your best. But when you don't get everything right, you seriously blame yourself. By recognizing that this can be a strength as well as a weakness, you should know that you simply can't get everything right, despite your best efforts.
20 Remind yourself that you can balance your level of over-thinking with more doing. You can even teach someone else who under thinks!
A. You may continue thinking about it even when you believe you have already let it go.
B. You assume that others know what you re thinking about.
C. Remember that, instead of just thinking, it's equally important to act.
D. You're proud of the act that you’re always thinking.
E. You look for meaning in everything.
F. It's even worse when you're unaware that you are just like this.
G. Can any of the above signs be found on you?
