Scientists have found a reliable way to lengthen life in lab animals:Reduce the amount of calories(卡路里)they eat.

This method,【1】(know)as caloric restriction, has been shown to lengthen life of organisms ( 有 機(jī)體 )and reduce some age-related【2】(disease).Whether it can do the same in people has been an open question. 【3】 ,a new study suggests that in adults, long-term restriction of calorie intake can have an effect on their health.

The researchers looked at a group of 143 healthy adults who ranged in age【4】21 to 50. They were instructed【5】(practice)caloric restriction for two years.They could eat the foods they wanted so long as they cut back on the foods they ate,with the aim of【6】(cut)the calories they consumed by 25 percent.

Many did not achieve that goal.On average,the dieters managed to cut down about 12 percent of their total calories, or【7】(rough)300 calories a day. But the group saw many of their health markers improve. They【8】(lose)body fat, their blood pressure fell slightly, and they had better blood sugar control. Meanwhile, another 75 healthy adults 【9】 did not practice caloric restriction saw no 【10】 (improve)in these markers.

【答案】

【1】known

【2】diseases

【3】However

【4】from

【5】to practice

【6】cutting

【7】roughly

【8】lost

【9】who/that

【10】improvement/improvements

【解析】

這是一篇說明文。介紹了一種延長(zhǎng)有機(jī)體壽命的可靠方法：熱量（卡路里）限制。

【1】考查非謂語動(dòng)詞。主句中主謂賓齊全，要填詞應(yīng)為非謂語動(dòng)詞，作定語修飾主語this method ，非謂語動(dòng)詞的邏輯主語method和動(dòng)詞know之間是被動(dòng)關(guān)系，所以要用V-ed形式，故填known。

【2】考查名詞復(fù)數(shù)。disease為可數(shù)名詞，前面的修飾詞為some，所以要用其復(fù)數(shù)形式，故填diseases。

【3】考查副詞。上文……has been an open question，這一研究成果是否適合于人類還有疑問，下文……can have an effect on their health，對(duì)人的健康能夠產(chǎn)生影響，前后句的意思相反，邏輯關(guān)系是轉(zhuǎn)折，所以用表示轉(zhuǎn)折的詞，填空詞后有逗號(hào)，不能填連詞but，故填However。

【4】考查介詞。from ……to從……到……，固定搭配，從21歲到50歲，故填from。

【5】考查非謂語動(dòng)詞。instruct后跟動(dòng)詞不定式作賓語，故填to practice。

【6】考查非謂語動(dòng)詞。介詞of后跟代詞、名詞或動(dòng)名詞，故填cutting。

【7】考查副詞。所填詞修飾cut down，動(dòng)詞短語，所以要用副詞，故填roughly。

【8】考查時(shí)態(tài)。句子在介紹做過的研究，已經(jīng)發(fā)生的事件，上下文都是用的一般過去時(shí)，所以填空詞也要用一般過去時(shí)，故填lost。

【9】考查限制性定語從句。先行詞為adults，指人，關(guān)系代詞在限制性定語從句中作主語，所以可用who或that，故填who/that。

【10】考查名詞（名詞復(fù)數(shù)）。動(dòng)詞saw后跟名詞作其賓語，所以要用improve的名詞形式，在no后的名詞improvement即可以用單數(shù)形式，又可以用復(fù)數(shù)形式，故填improvement/ improvements。

【題目】Directions: After reading the passage below, fill in the blanks to make the passages coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.

Dear Myself,

Life is scary. One day you wake up feeling like you can take over the world, and the next day you wake up 【1】 (feel) like all you want to do is lay in bed and hide from everything.

People walk into your life, grab your hand, and lead you to 【2】 (beautiful) path you've known, but sometimes the same people let go of your hand without warning, and you become 【3】 (strand) at a place where you never thought you'd feel lost.

Let's be honest, sometimes everything is going so great and it seems like nothing could go wrong, but right when you begin to think that, something so horrible comes 【4】 (crash) down and all of a sudden more problems come ricocheting（彈跳）around you and you just feel so hopeless because it's so bad.

【5】 is so hard to understand why such things happen in life, and I personally wish I had an answer to that "why"? you always ask yourself, but all I can say that is no matter 【6】 hard life gets, you have to keep going. The life around you will never stop going on.

I'll be honest and say that sometimes I feel a little bit worried and all I can think is "Will I be able to keep up? What if everything goes too fast?" But I realized 【7】 being scared and living with that burden of running away from problems only slow me down even more.

And I've come to the point 【8】 I believe that because life never stops, I shouldn't stop either. It's okay to take break and to give yourself time 【9】 (heal), but you cannot give up and you cannot quit.

Keep positive, fill your heart with gratitude for what you already have, and always 【10】 (remind) to humble and true to who you are!

With Love,

Your Soul

【題目】閱讀下面，根據(jù)所給情節(jié)進(jìn)行續(xù)寫，使之構(gòu)成一個(gè)完整的故事。(滿分25分)

Christine closed the door to Anna’s room. Inside, her classmate and friend had fallen asleep.

Downstairs, Christine’s mom, Donna, was grasping Anna’s mother Sheila around the shoulders.

“We should go,” she said. “Get some rest, huh?” Sheila nodded, blew her nose, and then waved them goodbye.

On the car ride home, Christine worked up the courage to ask the question on her mind. “Mom? Why was Sheila weeping?” She thought she knew the answer, of course: Anna’s cancer. In the past, Anna had been the neighborhood do-gooder, always going door to door for various causes: the local animal shelter, suffering children in Africa, or the families who’d lost their homes to fire. Now Anna could barely feed or dress herself. Christine thought it so unfair when bad things like this happened to good people.

“Well, it’s complex, but I guess you’re old enough to understand.”

“Understand what?”

“Understand that Anna is sick, yes, but Anna actually gets a lot of help. The government helps pay for a lot of her medicine. She gets meals delivered to her by a nonprofit. She even gets massages from local volunteers.”

“Wow!”

“Her life’s still very hard, of course, and no one would trade places with her, but when you have cancer, everyone can see that you need help, “continued Donna.” They don’t always see that the people around you are suffering.”

“People like Sheila?”

“Yes, did you know that Sheila took a break from her job to stay home with Anna?”

“No!” Christine was surprised. She had never thought about who took Anna to her appointments, or fed her when she was too weak to lift a spoon. Of course it was her family.

“Yes. So that means that many of the things they used to do with that extra money are all out the window now. They’re even worried now about keeping the house.”

“Their house? So Anna might have to move, while she’s sick?”

“If she doesn’t get better soon, and the bills keep piling up...” Donna pulled into the driveway, and just in time. Her cheeks were shining with tears.

注意:

1. 所續(xù)寫短文的詞數(shù)應(yīng)為150左右；

2. 至少使用5個(gè)以上短文中標(biāo)有下劃線的關(guān)鍵詞語；

3. 續(xù)寫部分分為兩段，每段的開頭語已為你寫好；

4. 續(xù)寫完成后，使用下劃線標(biāo)出你所使用的關(guān)鍵詞語。

Paragraph 1.

“There has to be something done for them,” Christine said firmly to their classmates and friends.

Paragraph 2.

But the best part of the party was when Anna came through the door with her family, attracted with promises of a chocolate cake and live music.
