【題目】Each year 【1】(thousand) of tourists visit the polar regions of the Arctic and Antarctica. But the increasing number of people traveling to the ends of the Earth can have【2】negative effect on fragile ecosystems. Should tourists【3】(allow) to visit polar regions?

About 40,000 tourists visit Antarctica each year. More than five million travel to the Arctic and sub-Arctic. Transporting tourists to the regions 【4】(increase) ship and airplane traffic, adding to the risk of pollution, oil spills, and other 【5】(environment) damage. Because the places where wildlife is accessible 【6】(be) few in number, tourist traffic can become concentrated in specific areas, 【7】(put)Arctic vegetation at risk.

Others say that access【8】 these very special parts of the world should not be restricted to only researchers and scientists. Polar tourism allows people to develop deep 【9】（person） connections with polar regions. “Those 【10】 travel to the Arctic or Antarctica often become cheerleaders for supporting those places.” Jim Sano, vice president for travel and conservation at World Wildlife Fund, told TFK.

【答案】

【1】thousands

【2】a

【3】be allowed

【4】increases

【5】environmental

【6】are

【7】putting

【8】to

【9】personal

【10】who

【解析】本文為介紹說明文。文章介紹了每年有成千上萬的游客前往北極和南極地區(qū)，人們對此所持有的不同觀點。

【1】考查數(shù)詞用法。固定詞組：thousands of“成千上萬的”。句意：每年有成千上萬的游客前往北極和南極地區(qū)。故填thousands。

【2】考查冠詞。固定詞組：have an effect on“對……有影響”，因為negative是輔音音素開頭的詞，應使用不定冠詞a。故填 a。

【3】考查被動語態(tài)。句意：游客們應該被允許參觀極地地區(qū)嗎？根據(jù)句意，此處應使用被動語態(tài)。故填be allowed。

【4】考查主謂一致。句意：運送游客到該地區(qū)增加了船只和飛機的交通，增加了污染、漏油和其他……的風險。此處描述的是客觀事實，應使用一般現(xiàn)在時，主語為動名詞詞組Transporting tourists to the regions，謂語動詞應使用第三人稱單數(shù)形式。故填increases。

【5】考查詞性轉化。此處修飾damage，應使用形容詞，意為“環(huán)境方面的破壞”。故填environmental。

【6】考查主謂一致。此處描述的是客觀事實，應使用一般現(xiàn)在時，主語為the places，句子，謂語動詞應使用復數(shù)形式。故填are。

【7】考查非謂語動詞。此處與主語tourist traffic 構成邏輯主動關系，應使用現(xiàn)在分詞。故填putting。

【8】考查介詞搭配。access to“……的權限”為固定搭配。故填to。

【9】考查詞性轉化。此處修飾connections，作定語，應使用形容詞形式，意為“私人關系”。故填personal。

【10】考查定語從句。此處為定語從句，先行詞是those（那些人），連詞在從句中作主語。故填who。

【題目】根據(jù)短文內容, 從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。
There are a lot of people who are overweight all over the world. What causes obesity? If you get the gene(基因), well, probably you are going to be a few more pounds heavier compared to the rest of your classmates or friends. Obesity can not only make a person look heavy, and not in the usual sense of being handsome, but can also lead to serious health conditions and life-threatening diseases.
Indeed, junk food has been blamed for the prevalence(流行）of obesity. It is called junk food, because hamburger, pizza and the like contain high calories. If you eat a Big Mac (a super hamburger), an order of large fries, and a large Coke, you will need to walk non-stop for six hours to burn off the calories you have gained. And don't be fooled by soft drinks, which are high in sugar and are a major cause of obesity.
Popular sugary drinks, of course, include Coca Cola, Pepsi(百事) Cola, and many new brands that appear on the market every couple of days.
Just one 20-ounce (about 567g) bottle of soda can have 250 calories, which are equal to more than 16 teaspoons of added sugars. Even a lemon-flavored iced tea can have 210 calories.
Next time, when you are ready to eat that huge Mac and to drink that two-liter bottle of Pepsi, probably it's a good idea to give it a second thought.
A. Obesity is more common in women than men.
B. Most people don't realize how easy it is to gain weight from drink sugar-sweetened beverages(飲料)
C. When we talk about obesity, the first thought that comes to mind is: junk food.
D. The unburnt calories will put weight on you.
E. Keeping healthy is our own responsibility.
F. Because of their high content of sugar, soft drinks are also called sugary drinks.
G. However, the most common cause of obesity is eating too much, especially too much junk food.

【題目】根據(jù)短文理解，選擇正確答案。
Traffic problems are an everyday concern in many cities, including Washington, D. C. A growing number of Washingtonians are turning to bicycles to get to and from work. In fact, the number of commuters who use bicycles has doubled in the city since 2007.
Ralph Buehler teaches urban planning at the Virginia Polytechnic Institute and State University，popularly known as Virginia Tech. He has written a book about urban biking, called City Cycling. He says there is a reason why urban bike tiding is now becoming more popular.
“Over the last 60 to 70 years, cities in America have been adapted to the automobile.”
“Most cities took advantage of the money coming for the interstate (洲際)highway system, from the federal government, starting in 1956. There was a 90 percent federal match(補貼)so the cities only had to put up 10%. It was very tempting.(臨時的).”
In the years after World War Two, many Americans moved to suburban communities, just outside major cities, They decided to travel great distances to and from work in exchange for a home in the suburbs. Their cars became a symbol of freedom.
But today, many people believe they can save money by living in the city.
Greg Billing is with the Washington Area Bicyclist Association. “When a person makes a change from using a car to using a bike, he/she is saving anywhere between 8 or$9,000 a year.”
Ralph Buehler says governments save money when people use bicycles. “Building bicycling facilities(設施) is much cheaper than building and maintaining road facilities or public transport.”
Washington, D.C has also taken steps to protect bike riders. It approved a safe passing law and created areas on the road between cars and bikes.
The United States Census Bureau says 4% of the city's workers ride to work by bike. The only city on the East Coast with more bike commuters is New York.

【題目】根據(jù)短文內容的理解, 選擇正確答案。 English is the most widely used language in the history of our planet. One in every seven human beings can speak it. More than half of the world's books and three quarters of international mail are in English. Of all languages, English has the largest vocabulary--perhaps as many as two million words.
However, let's face it: English is a crazy language. There is no egg in an eggplant, neither pine nor apple in a pineapple and no ham in a hamburger. Sweetmeats are candy, while sweetbreads, which aren't sweet, are meat.
We take English for granted. But when we explore its paradoxes（自相矛盾的說法), we find that quicksand can work slowly, boxing rings are square, public bathrooms have no baths in them.
And why is it that a writer writes, but fingers don't fing, grocers don't groce, and hammers don't ham? If the plural of tooth is teeth, shouldn't the plural of booth be beeth? One goose, two geese--so one moose, two meese?
How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? How can overlook and oversee be opposites, while quite a lot and quite a few are alike? How can the weather be hot as hell one day and cold as hell the next?
English was invented by people, not computers, and it reflects the creativity of human beings. That's why, when stars are out, they are visible; but when the lights are out, they are invisible. And why, when I wind up my watch, I start it; but when I wind up this essay, I end it.
（1）What does the first paragraph mainly talk about?
A.English has a long history.
B.English is widely spread.
C.English makes a great difference
D.English is used to translate books.
（2）Which of the following includes two items that have the similar meaning?
A.A wise man and a wise guy.
B.Overlook and oversee.
C.Quite a lot and quite a few.
D.Hot as hell and cold as hell.
（3）The underlined words "wind up" in the last paragraph probably mean "______".
A.blow
B.roll up
C.get hurt
D.finish
（4）What does the last paragraph want to show?
A.Human beings are very clever.
B.English is difficult to learn.
C.There are too many words in English.
D.The same words have different meanings.

【題目】Most students have had an experience of putting off things that must be done before a certain time. Here are some ways to help you reduce this age-old practice.

【1】

In order to achieve a particular result, you should constantly set and update goals. It can be beneficial to mark all deadlines in a planner and think about how much time you need to meet them all. What is more, make a daily schedule in order to reach necessary goals before going to bed.

【2】

Sometimes you may consider some work or class pointless and not useful to your further studies. However, when these thoughts arise, remind yourself what the final goal of your schooling is. Remind yourself why you wanted to go to school and take this program in the first place.

【3】

The most common things that take your attention away are those found on the Internet-social media sites, and videos. If you do not need the Internet to do your work, turn it off so that you are not receiving notices while completing your work.

Have something to look forward to.

Being productive for all hours of every day does not work, so plan time to go out with friends or do something relaxing. This way, while you are working, you can keep in mind that once you are finished your work you can go out and not worry about your assignments.

A. Reward yourself.

B. Turn off the Internet.

C. Set goals.

D. Remind yourself of what you are doing.
