While being lost in the woods can be a frightening experience, surviving alone in the wild is generally a matter of common sense, patience, and wisely using the gifts that nature provides.1..

Do your research first. Don't just trek off into the wilderness; get a solid understanding of your surroundings first. Studying a map of the area where you're going -- and making sure to bring it with you -- will increase your chances of not getting lost tremendously. Educate yourself about the flora and fauna of the area you are exploring. 2..

3.. A cell phone with a spare battery or a portable CB radio can be your best, quickest means of rescue if you are truly lost or injured. A cell signal may only be obtainable only from a hill or tree, but is better than nothing. Serious hikers may even consider investing in a personal locator beacon such as the SPOT Messenger for extended, precarious, or very remote, treks.

Don't panic if you’re lost. Panic is more dangerous than almost anything else, because it interferes with the operation of your single best, most useful and versatile survival tool: your mind. The moment you realize that you are lost, before you do anything else, stop.4.. Before you act, follow the idea of STOP: S = sit down T = think　O = observe your surroundings P = prepare for survival by gathering materials.

Signal your location. Make noise by whistling, shouting, singing, or banging rocks together. 5. . If you're in a mountain meadow, make three piles of dark leaves or branches in a triangle. In sandy areas, make a large triangle in the sand. Three of anything in the wilderness is a standard distress signal.

A. Bring a means of communication.

B. If you can, mark your location in such a way that it's visible from the air.

C. Knowledge of the local plants and animals can save your life

D. If you want to know how to survive in the woods, just follow these steps.

E. Starvation won't be a big problem.

F. Take a deep breath and stay calm.

G. Having strength in numbers will help you survive.

科目：高中英語(yǔ) 來(lái)源：湖北省2016-2017學(xué)年高一下學(xué)期期中聯(lián)考英語(yǔ)試卷（有答案） 題型：閱讀理解

Whether rich or poor, parents who have books in the home increase the level of education their children will attain, according to a 20-year study led by Mariah Evans.

For years, educators have thought the strongest predictor(預(yù)示物) of attaining high levels of education was having parents who were highly educated. But, the study showed that the difference between being raised in a bookless home compared to being raised in a home with a 500-book library has as great an effect on the level of education a child will attain as the difference between having parents who are barely literate (有文化的) and having parents who have a university education.

Being a sociologist, Evans was particularly interested to find that children of lesser-educated parents benefit the most from having books in the home. What kinds of investments should we make to help these kids get ahead? The results of this study indicate that getting some books into their homes is an inexpensive way that we can help these children succeed. Evans said, "Even a little bit goes a long way. Having as few as 20 books in the home still has a significant impact on motivating a child to a higher level of education, and the more books you add, the greater benefit the children get.”

The researchers were struck by the strong effect having books in the home had on children's educational attainment even above and beyond such factors as education level of the parents, the father's occupation or the economic level of the country.

Having books in the home is twice as important as the father's education level, and more important than whether a child was brought up in a developing country or a developed country. Surprisingly, the difference in educational attainment for children born in developed country and children born in developing country was just 2 years, less than two-thirds of the effect that having 500 or more books in the home had on children.

1.In the past educators held a point of view that ______ .

A. children whose family had a library would possibly attain high levels of education

B. children who were born in poor families studied harder than those in rich families

C. children whose parents are highly educated would attain high levels of education

D. parents’ level of education had nothing to do with their children’s levels of education

2.What does the underlined word “motivating” in Paragraph 3 mean?

A. Making somebody want to do something.

B. Helping somebody to finish something

C. Making somebody pretend to do something.

D. Preventing somebody from achieving something.

3.Which of the following has the most important effect on the level of education a child will gain?

A. The economic level of the country.

B. The father’s occupation.

C. Education levels of parents.

D. Having books in the home.

4.Which is the following is NOT TRUE?

A. Getting books into homes is good investment parents can make.

B. Children who get a higher level of education must have many books in their homes.

C. Reading books is good for the development of children.

D. Books in home have a great effect on children’s education levels.

A new study reported in a medical magazine concludes that even smokers who reach their 70s are likely to live longer if they stop smoking. Researchers say that they have got some of the strongest evidence (證據(jù)) that it's never too late to stop smoking.

The study was based on a five-year follow-up of 7, 178 people over the age of 65 who lived in Boston, New Haven and Washington counties in Iowa. The report showed former smokers ran about the same risk of death from heart disease as those who never smoked. Women who stopped smoking faced about the same cancer-death risk as those who never smoked, but men who gave up smoking still had a 50% higher risk. The men's extra risk of cancer largely disappeared if they had not smoked for more than 20 years. The discovery does not agree with the widely-known belief that by the time smokers reach old age, their habit has already hurt them, and those who continue to live healthily are probably immune (有免疫力的) to the dangers of cigarettes.

1.The conclusion of the new study is that _________.

A. one can plan to give up smoking at any age for the sake (理由) of one's health

B. it's late to stop smoking when one is getting old

C. it's no use for young people stopping smoking

D. smokers over the age of 70 are expected to live longer

2.A former smoker is a person who _________.

A. smokes once in a while

B. is going to give up smoking

C. used to smoke

D. smokes a lot

3.Which of the following statements is NOT TRUE according to the passage?

A. Women who stop smoking face about the same cancer-death risk as non-smokers.

B. Men who stop smoking are facing the same risk of death from cancer as non-smokers.

C. Women who stop smoking face about the same cancer-death risk as men who gave up smoking 20 years ago.

D. Men who stop smoking face about the same risk of death from heart trouble as non-smokers.

Younger students experience school bullying (欺凌) more frequently than older ones, and male students are bullied more than their female peers, a survey found.

It also found that nearly half of students had been intentionally hit or knocked down by classmates. About 6 percent said they are targeted by bullies on campus every day. The survey also found that students from ordinary schools experienced more bullying than peers from key institutions, and children from poor families are more likely to be bullied at school.

Being bullied can have a negative impact on a child’s personal development and academic performance, according to Zhou Jinyan, a researcher who led the study at Beijing Normal University. “Children being bullied will find it hard to trust others,” Zhou said. “They may often feel anxiety, anger, resentment or depression. These emotions will further undermine their ability to control their own life.”

In recent years, bullying on Chinese campuses has been frequently reported and has attracted widespread attention and concern. The most recent incident to arouse heated discussions took place in December at Beijing’s Zhongguancun No.2 Primary School. A fourth-grade student was bullied and laughed at by classmates, causing him acute stress disorder.

The Supreme People’s Procuratorate (最高人民檢察院) received about 1,900 cases related to school bullying in 2016. Meanwhile, there was a notable increase in bullying reports involving middle school students from 14 to 18 years old.

Zhou came up with some ways to solve the problem, including boosting communication between teachers, parents and students and trying to establish more harmonious relationships among children. She said it was strongly suggested that parents try to be involved in their children’s educational experience, as their presence and companionship have proved effective in reducing bullying and its negative effects.

1.Who is the most likely to become the target of bullying?

A. A 10-year-old girl from a key school

B. A 10-year-old boy from a poor family

2.Being bullied will cause students to go through the following EXCEPT _____.

A. a drop in academic performance

A. bullying at school usually leads to acute stress disorder
