Going online to do research when you're writing papers and doing projects is natural thing to do. Knowing how to evaluate and choose online resources can help you avoid headaches and wasting time.
How can you make researching online as easy and effective as possible? Before you begin your research, make a list of the kinds of sites that are best for your topic. Is the website reliable and up to date? Government sites ending in . gov and educational sites ending in .edu usually are safe bets. Established news-related sites are OK, too, but be sure that you're using the original source. If a newspaper article mentions another source, like an organization or website, go directly to that source to find the information.
They can be good resources, but it's always best to check with your teacher to make sure he or she considers the site appropriate. Wikipedia. Org is popular and ranks highly in search results, but it can be edited by anyone, whether a person has accurate knowledge of the topic or not.
On commercial websites ending in .com, check to see if the site has advertising. And bogs, personal websites and social media sites are more likely to give personal opinions rather than facts.
A. Check to see if the author is identified and sources are given.
B. That's why it helps to know the best sites for your needs.
C. But all of the choices at your fingertips can seem overwhelming sometimes..
D. Sites ending in .org are usually run by non-profit organizations.
E. Many schools block access to images or websites that may be valuable to your research
F. At most schools, using Wikipedia as a source is not a good way to build credibility.
G. If it does, it may be biased(有偏見(jiàn)的), since it's trying to sell a product

【答案】C；A；D；F；G
【解析】本文是一篇說(shuō)明文，當(dāng)你寫(xiě)論文和做項(xiàng)目時(shí)，上網(wǎng)做研究是很自然的事情。但是，你應(yīng)該注意些什么呢？
（1）考查上下文理解和邏輯推理。根據(jù)空前“ Going online to do research when you're writing papers and doing projects is natural thing to do. “上網(wǎng)做研究是很自然的事情；以及空后”Knowing how to evaluate and choose online resources can help you avoid headaches and wasting time.“知道如何評(píng)價(jià)和 選擇在線資源可以幫助你避免麻煩和浪費(fèi)時(shí)間，所以中間這句應(yīng)該是句意的轉(zhuǎn)折，說(shuō)明有時(shí)候在 網(wǎng)上搜索資源是很費(fèi)時(shí)費(fèi)力的。故選C。
（2）考查上下文理解和邏輯推理。根據(jù)空前“make a list of the kinds of sites that are best for your topic. Is the website reliable and up to date?”可知，網(wǎng)上搜索資源的時(shí)候首先要對(duì)網(wǎng)站和作者進(jìn)行了解。故選 A。
（3）考查上下文理解和邏輯推理。根據(jù)空后“Wikipedia. Org is popular and ranks highly in search results…” 相對(duì)應(yīng)，此處也是在講一些網(wǎng)站的特點(diǎn)，所以D項(xiàng)內(nèi)容符合上下文。故選D。
（4）考查上下文理解和邏輯推理。根據(jù)空前“but it can be edited by anyone, whether a person has accurate knowledge of the topic or not.”可知，使用Wikipedia網(wǎng)站的資源并不好。故選F。
（5）考查上下文理解和邏輯推理。根據(jù)空前“check to see if the site has advertising. ”可知，有些商業(yè)網(wǎng)站可能會(huì)推銷(xiāo)產(chǎn)品。故選G。

【題目】閱讀理解
Mike Miles hadn't had a stable job in years. He bounced around from one position to another, never sure when his last day would be. Sometimes, he lost a position with less than a day's notice. This wasn't due to a poor work ethic—from arriving early to staying late, Miles says he did everything he could to build a good relationship with employers. But because Miles had a criminal record, he was always cut loose when it came time to let staff go.
It wasn't until October 2015, nearly a decade after his release from prison, that a cousin told Miles about Lancaster Food Company, a local business that focuses on hiring people released from prison. Hoping this would clear up what felt like a thick cloud of uncertainty over his future, Miles submitted an application. He got an interview, and he then began a new job.
Miles' scenario is rare in Lancaster, where the poverty rate holds steady at 30%. This figure riled Charlie Crystle, Lancaster's co-founder and CEO. Crystle was raised in Lancaster but left in 1986 to purse a college degree and later, a career in technology. He co-founded four tech companies, one of which sold for millions of dollars back in 2000.
Crystle is skeptical that many of Lancaster's low-income residents can get started the way he did. He believes food production is a key way to meet former offenders who may lack a college degree. Lancaster produces products like bread. Nowadays the company is rapidly expanding; however, at just 16 full-time employees, including administration and owners, it doesn't lower the city's poverty rate.
Crystle says he wants to inspire other companies to rethink their current practices and start conversations around minimum wage and employment opportunities for everyone, including ex-offenders. Dan Jurman, who chairs the city's Commission to Combat Poverty, believes that Crystle's business is a great way to make this happen. "None of us can handle these issues alone, " he said.
（1）The purpose of the first paragraph is to show __________ .
A.a man's difficulty in living a stable life
B.an increasingly competitive workplace
C.a decrease in employment opportunities
D.the reason why Lancaster Food Company was founded
（2）What does the underlined word "riled" in Paragraph 3 most probably mean?
A.Annoyed.
B.Discouraged.
C.Amused.
D.Embarrassed.
（3）What words can best describe Charlie Crystle according to the text?
A.Outgoing, kind and considerate.
B.Wealthy but a little bit greedy.
C.Humorous, diligent and ambitious.
D.Successful and socially responsible.
（4）In Dan Jurman's opinion, what is the biggest achievement of Lancaster Food Company?
A.It greatly increases employment opportunities.
B.It suggests an idea for fighting poverty.
C.It provides a way to handle ex-offenders.
D.It creates a stable environment for people.

【題目】根據(jù)短文理解，選擇正確答案。
Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保護(hù)) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That's why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.
Years ago, over hunting and the ivory trade were the biggest threats to elephants survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.
The 21st century brings a different challenge to elephant conservation —land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (沖突) between local farmers and these big animals.
Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.
AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.
The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.
（1）The first paragraph of the text is mainly to tell readers _____.
A.African elephants are endangered now
B.there remains a lot to do to protect African elephants
C.African elephants are popular animals
D.the number of African elephants has increased over the years
（2）What is the biggest difficulty in protecting African elephants now?
A.They are still being killed.
B.Their habitats are being destroyed.
C.They don't have enough food.
D.They can't live in peace with farmers.
（3）To protect elephants, the AWF does all the following EXCEPT _____.
A.keeping elephants
B.protecting elephants' habitats
C.doing research on elephants
D.helping farmers improve their life
（4）What is the best title for the text?
A.African elephants conservation
B.Living with African elephants
C.African elephants' situation
D.African elephants being endangered

Everyone can't live without money. However, money cannot buy everything. You can't buy the following things only relying on money you have.
Time
Money is a tool for trade. We spend most of our time on this earth getting, spending, worrying and fantasying about money. Instead, money takes away your time that could have been spent playing with your children or having a long walk with your friends. When the sun sets, a day goes away from our life forever. No money has power to bring that back to life.
Self-respect
There are a lot of examples to prove that no money can buy self-respect. If you are your worst enemy, gods of money can't save you from the self-destruction you add to yourself.
Health
As I write this, I found out that one of my best friends has brain cancer, and it is in the last period. But no money can buy insurance for his life. We buy insurance for just about everything including our life but money can never bring life back.
Happiness
This is controversial(有爭(zhēng)議的). Money can buy happiness if it is spent bringing greater financial safety for the family. Going after money every day can never find its destination with frequent eagerness to get more .
A. Show your respect for others.
B. Self-respect is got from within.
C. Money can buy a lot of things.
D. You can't buy the time or save it in your storeroom.

F. So you should not try your best to earn money without caring about your health.
G. But money can't buy happiness if the purpose is to make money to make other people happy.

【題目】閱讀理解。
Tornadoes are nature's most violent storms, which can cause deaths and destroy a neighborhood in seconds. A tornado appears as a funnel-shaped (漏斗狀) cloud from a thunderstorm to the ground with whirling (飛快移動(dòng)) winds that can reach 300 miles per hour. Damage paths can be over one mile wide and 50 miles long. Every state is at some risk from this disaster.
Some tornadoes can be seen clearly, while rain or nearby low-hanging clouds obscure others. At many times, tornadoes develop so rapidly that little, if any, advance warning is possible.
Before a tornado hits, the air may become very still. A cloud of debris (散片) can mark the location of a tornado even if a funnel can not be seen. Tornadoes generally occur near the edge of a thunderstorm, when the strong wind may die down. It is not uncommon to see clear, sunlit skies behind a tornado.
The following are facts about tornadoes:
The average forward speed of a tornado is 30 MPH, but may also vary from still to 70 MPH. Debris is picked up or a cloud forms in the funnel.
The average tornado moves from southwest to northeast, but tornadoes have been known to move in any direction. Tornadoes are most often reported east of the Rocky Mountains during spring and summer months.
Tornadoes can happen together with tropical storms and hurricanes as they move onto land. Waterspouts are tornadoes that form over water.
The tornado season in the southern states of America is March through May; in the northern states, it is late spring through early summer. Tornadoes are most likely to occur between 3 p.m. and 9 p.m., but can occur at any time.
（1）From the passage, where may tornadoes come from?
A.Hurricanes.
B.Great heat.
C.Thunderstorms.
D.Sandstorms.
（2）What does the underlined word “obscure” probably mean?
A.Hide.
B.Reduce.
C.Produce.
D.Raise.
（3）When a tornado happens, ________.
A.it often reaches the speed of 70 MPH
B.it can only be seen in the late of the day
C.it may form on the surface of sea water
D.it only moves from southwest to northeast
（4）The passage makes us believe that ________.
A.tornadoes are mostly seen in the southern states of America
B.warnings about tornadoes are well developed in many countries
C.of all the natural disasters, tornadoes often cause the biggest damage
D.tornadoes may strike so quickly that there is often little or no warning
