【題目】 Price decrease farmers’ income, the central government has decided to buy more crops to protect them.

A. Preventing; to affect B. To prevent; affecting

C. Preventing; affected D. To prevent; being affected

【答案】B

【解析】考查非謂語動詞和固定搭配。句意：為了阻止價格下降影響農(nóng)民們的收入，中央政府已經(jīng)決定購買更多的農(nóng)作物來保護他們。第一空是動詞不定式做目的狀語；第二空是固定搭配：prevent sb. （from）doing sth.阻止某人做某事，故答案為B。

【題目】根據(jù)短文內(nèi)容，從短文后的七個選項中選出正確的填入空白處。選項中有兩項為多余選項。
The Science of Risk-Seeking
Sometimes we decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth taking. Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work.
The reason why any of us take any risks at all might have to do with early humans. Risk-takers were better at hunting, fighting, orexploring. As the quality of Risk-taking was passed from on ration to the next, humans ended up with a sense of adventure and a tolerance for risk.
So why aren’t we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one Killed. A few daring survived, though,along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe youlove car racing, or maybe you hate it.
No matter where you are on the risk-seeking range,scientists say that your willingness to take risks increases during your teenage years. Tohelp you do that, your brain increases your hunger for new experiences.
New experiences often mean taking some risks, so your brain raises your tolerance for risk as well.
Mean taking some risks, so your brain raisers your tolerance for risk as well.
For the risk-seekers a partof the brain related to pleasure becomes active, while for the rest of us, a part of the brain related to fear becomes active.
As experts continueto study the science of risk-seeking, we’ll continue to hit the mountains, the waves or the shallow end of the pool.
A. It all depends on your character.
B. Those are the risks you shouldjump to take.
C. Being better at those thingsmeant a greater chance of survival.
D. Thus, these well-equipped people survived becausethey were the fittest.
E. This is when you start to move away from your family and into thebigger world.
F. However, we are not all using the same reference standard to weighrisks and rewards.
G. New brain research suggests our brains work differently when weface a nervous situation.

【題目】語篇填空，閱讀下面短文，按照句子結構的語法性和上下文連貫的要求，在空格處填入一個適當?shù)脑~或使用括號中詞語的正確形式填空。
Creating good habits can be as tough as breaking bad habits. From my experience, one of the most important factors make forming a new habit hard is that a lot of willpower (require), at least in the beginning, and that alone can prevent many people correctly developing their desired habits.
Now instead of just using willpower and reminding (you) to start the new habit each day, why don't you just link it to an existing one? I have done experience. It started with just 20 pushups (俯臥撐), something easy. So before I showered each day, I would do the pushups. a couple of days, I increased the amount just to make it a bit more challenging.
Gradually, over the course of about 3 months, I'm now doing 100 pushups. And as the habit grew stronger, it got easier to do so (natural). Now I know the habit is pretty much ingrained (根深蒂固), for I feel like something is missing I don't do this before showering. I found it pretty easy (create) this habit and not much willpower was involved.
I think the key, apart from using an (exist) habit, is to start out with something really easy. Once that starts becoming part of your (day) routine, add on to it.

【題目】What makes a gift special? Is it the price you see on the gift receipt? Or is it the look on the recipient's face when they receive it that determines the true value? What gift is worth the most?

This Christmas I was debating what to give my father. My dad is a hard person to buy for because he never wants anything. I pulled out my phone to read a text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father. My eyes fell on a photo of a flower taken in Wyoming, and underneath a poem by William Blake. The flower, a lone dandelion standing against the bright blue sky, inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.

I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the creamcolored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind. The poem was written by Edgar Allan Poe; my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was focused around dreaming, and after searching I found the perfect picture. The image was painted with blues and greens and purples, twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer, the white paper coloring with words that shaped my childhood. I felt that this was a gift that my father would truly appreciate.

Christmas soon arrived. The minute I saw the look on my dad's face as he unwrapped those swirling black letters carefully placed in a cheap frame; I knew I had given the perfect gift.

【1】The author's inspiration for the gift came from ________．

A. a photo of a flower

B. a story about a kid

C. a call from the mother

D. a text about Christmas

【2】The underlined word “it” in Paragraph 3 refers to a poem by “________”．

A. the father B. the author

C. William Blake D. Edgar Allan Poe

【3】The author made the gift by ________．

A. searching for the poems online

B. drawing the background by hand

C. painting the letters in three colors

D. matching the words with pictures

【題目】The Value of Tears

Tears can ruin make-up, bring conversation to a stop, and give you a runny nose．Tears leave you embarrassed and without energy．Still, crying is a fact of life, and your tears are very useful．Even when you're not crying, they make a film over the eye's surface．【1】

When tears fall, they reduce stress．But we tend to fight them for all! sorts of reasons． "People worry about showing their emotions , afraid that once they lose control they'll never get it back．"【2】. After we cry, the feelings that caused the tears often disappear．

Sometimes people become much stressed and can't cry. Whatever emotion they are feeling—shock, anger, fear, or sadness—is being held back．

But everyone has the need to cry. Psychologist Vera Diamond explains that her treatment often consists of giving people permission to cry．【3】 Patients practice crying just to become used to expressing emotions．She suggests safe, private places to cry, like under the bedcovers or in the car．Crying is a way of reducing tension, but people don't like it when others cry because it makes them tense．【4】 And they'll do just about anything to make you stop．

In certain situations, such as at work, tears are not appropriate．It's good not to cry during a tense business discussion．【5】You should also act out the whole situation again and be as noisy and angry as you like．It will help you feel better． "And," she adds, "Once your tears have taken away the stress, you can begin to think calmly of ways to deal with the problem．"

Tears are a sign of our ability to feel．If you find yourself near someone crying, deal with it．And never be afraid to cry yourself．

A．She gives crying exercises．

B．They cry for different reasons．

C．They too may be holding back a need to cry．

D．The fact is that no emotion lasts forever．

E．It contains a chemical against infection.

F．But once you're safely behind closed doors, don't just cry．

G．It forms in response to the stress on the surface of the eye．

How to Manage Your Phone's Data Use
Smart phones give you access to a wealth of information and media, but most networks put a limit on the amount of data you can use each month. A typical phone contract includes a data allowance of between 500MB and 10GB per month. You see, your usage can mount up surprisingly quickly – watching a film on the phone is about 700MB in SD, an hour of streaming TV is around 500MB or 60-140MB for the same of radio, chatting on Skype for an hour is around 40MB.
If possible, wait until you can connect to free Wi-Fi before using your phone's data features.
When you are on the road, use your car's GPS, not your phone, to find the way. But maps are preloaded in a GPS, making this free to use.
Many of these are funded by ads that pop up on your screen. Every ad has to download through your network, using up your data allowance.
If you regularly need to use a lot of data on your phone, consider a data-compressing(壓縮) app, such as Onavo(www.onavo.com). So you use less of your monthly allowance. You may have to subscribe to such compression services, so you'll need to weigh up whether it's worth the cost.

A. The more data, the higher the monthly cost.
B. Remember to use free Wi-Fi anywhere you go.
C. Try these tips to better manage your data use.
D. It compresses data before it is fed to your phone.
E. But you might end up paying more than expected.
F. The phone has to download map data as you move.
G. Be careful of how many “free” games you play on the phone.
