Do you scream on a roller coaster ride? You slowly climb up a steep slope until an almost vertical(垂直的) drop, and then... Ahhhhhhhh! Thrill-seekers like me are in luck because theme parks are pushing the boundaries of technology to create the fastest, tallest, scariest roller coasters the world has ever known.

Alton Towers in Britain opened the world's first 14-1oop roller coaster a few months ago, called The Smiler. Over in Abu Dhabi, Ferrari World claims to have the world's fastest one. Ferrari World's Formula Rossa ride sends out passengers from 0-240km/h in just 4. 9 seconds. During this rapid acceleration they experience G-forces only fighter pilots usually feel: Up to 4. 8G. The designer of several rides at Alton Towers, said: "While we can stand 6-8Gs for very short periods of time, ff we experience 5G for more than five seconds we're likely to "black out."

On modern roller coasters passengers experience about 3G in tight turns and loops. But while we may have reached the limit in terms of G-forces, there is no technological limit to how fast or how high roller coasters can go---it's all down to money. Alton Towers' The Smiler cost ~18m to build.

Some companies are finding other ways to keep us amused. There's a move towards indoor rides where the experience is improved by audio-visual technologies. For example, a company called Dynamic Structures is currently developing a "coal-mine-themed" ride for a client in Dubai that will combine speed and G-forces with 3D projection effects and robotics, which will trick your brain into thinking you're really falling.

I can't wait to enjoy this one. What about you: Do you like being upside down?

1.The underlined phrase "black out" in the second paragraph probably means .... .

A. stop breathing B. lose consciousness for a short time

C. lose memory forever D. bleed to death

2. We can learn from the passage that __

A. all the theme parks are creating the fast roller coasters

B. the Smiler sends out passengers from 0-240km/h in just 4.9 seconds

C. it is unusual for fighter pilots to feel up to 4.8G

D. the more the money is spent, the faster the roller coaster can go

3. The feature of the "coal-mine-themed" ride is

A. 3Dtechnologies B. indoor rides C. G-forces D. dynamic structures

4. What is the best title for the passage?

A. The Fastest Roller Coaster B. The Smiler and G-forces

C. Screaming for Fun D. The New Technology

 

1.B

2.D

3.A

4.C

【解析】本文介紹了在英國要開設(shè)的Alton Towers中使用了最刺激的過山車，并在文章中介紹了與過山車有關(guān)的其他信息。

1.B

【試題解析】推理題。根據(jù)本句The designer of several rides at Alton Towers, said: "While we can stand 6-8Gs for very short periods of time, ff we experience 5G for more than five seconds we're likely to "black out."可知通常我們可以短時間地承受6-8G，但是如果承受5G超過了5秒鐘，我們就會受不了。這已經(jīng)到了我們能夠承受的極限。身體會出現(xiàn)比較大的反應(yīng)，A項過于劇烈，B項較為貼切。

2.2】D

【試題解析】推理題。根據(jù)第3段1,2行But while we may have reached the limit in terms of G-forces, there is no technological limit to how fast or how high roller coasters can go---it's all down to money.可知在過山車的速度上是沒有技術(shù)的限制的，也就是說只要你能夠出得起錢，就可以獲得更快速度的過山車。所以D項說法是正確的。

3.3】A

【試題解析】細節(jié)題。根據(jù)文章倒數(shù)第二段For example, a company called Dynamic Structures is currently developing a "coal-mine-themed" ride for a client in Dubai that will combine speed and G-forces with 3D projection effects and robotics, which will trick your brain into thinking you're really falling.可知"coal-mine-themed"項目把速度和3D技術(shù)結(jié)合在一起了。3D技術(shù)是它的亮點。故A正確。

4.4】C

【試題解析】主旨大意題。根據(jù)文章主題段第一段Do you scream on a roller coaster ride? You slowly climb up a steep slope until an almost vertical(垂直的) drop, and then... Ahhhhhhhh! Thrill-seekers like me are in luck because theme parks are pushing the boundaries of technology to create the fastest, tallest, scariest roller coasters the world has ever known.可知本文主要敘述的是新型的過山車讓人尖叫并讓人非常刺激快樂。故C項符合上下文。

【長難句解析】

1. while we may have reached the limit in terms of G-forces, there is no technological limit to how fast or how high roller coasters can go---it's all down to money.

【翻譯】盡管我們在G-force方面到達了極限，但是在過山車的速度方面卻沒有技術(shù)方面的限制，這都取決于錢。

【分析】本句中的連詞while表示“盡管”，引導的是一個讓步狀語從句，相當于although。While有多種含義：當…時（與延續(xù)性動詞連用）；然而（表示輕微的轉(zhuǎn)折）。

2. There's a move towards indoor rides where the experience is improved by audio-visual technologies.

【翻譯】對于乘坐過山車有一個在室內(nèi)的趨勢，在這里可以通過視覺技術(shù)來改善這個經(jīng)歷。

【分析】本句中的where the experience is improved by audio-visual technologies是一個由關(guān)系副詞where引導的定語從句，修飾前面的先行詞move趨勢；因為后面的句子結(jié)構(gòu)很完整，所以要使用關(guān)系副詞來引導這個定語從句，where通常前面的先行詞都是表示地點的名詞，但是有時候表示抽象概念的名詞，如stage等也可以使用where來引導。

Counterfeit medicines are a widespread problem in developing countries. Like other counterfeits, they look like real products. But counterfeit drugs may contain too much, too little or none of the active ingredients (原料) of the real thing.

People do not get the medicine they need. And in some cases the counterfeits cause death. Twenty children in Bangladesh died last year after being given acetaminophen (醋氨芬). The medications contained ingredients that looked, smelled and tasted like the real thing. The medicine was produced by a local drug company that used a dangerous substitute to save money.

The problem of counterfeit medicines is especially serious in Africa, Asia and Latin America. The WHO estimates that up to thirty percent of medicines on sale in many of those countries are counterfeits. The problem is less widespread among industrialized countries. The WHO says counterfeits make up less than one percent of the illegal drug market in countries like the United States, Canada, Japan, and New Zealand.

But the agency also says as much as fifty percent of the medicine sold on the Internet is counterfeit.

Much is being done to fight counterfeit drugs. Several companies are developing ways to make counterfeits easier to identify (鑒定). And there are existing methods, like a machine that can quickly identify chemicals in pills to confirm if the pills are real. Other ideas include things like special tracking (跟蹤) codes for drug packages. People could send a text message with the code and get a message back, which proves that what they bought is listed in a database. Some drug makers and other companies put three-dimensional images called holograms (全息圖) on their products as a security device.

1.The underlined word “counterfeits” means _______.

A. qualified products B. sub-standard medicines

C. real pills D. false products

2. Last year twenty children in Bangladesh died because of _______.

A. unclean water B. acetaminophen

C. unreal drugs D. online medicines

3. We can draw a conclusion from the passage that ______.

A. we had better not buy medicines online

B. more and more people will buy products online

C. medicine companies don’t pay much attention to counterfeit drugs

D. it is very cheap and convenient to buy medicines online

4. What is the main idea of the last paragraph?

A. It shows the danger of counterfeit drugs

B. Special tracking codes for drug packages are used to identify counterfeits.

C. Some measures are being taken to fight counterfeit drugs

D. It reveals the reasons why counterfeit drugs are widespread.

5. Which of the following country may have serious problems of counterfeit medicines?

A. France. B. America

C. New Zealand D. India

Dear Dad,

Today I was at the shopping mall and I spent a lot of time reading the Father's Day cards. They all had a special message that in some way or another reflected how I feel about you. Yet as I selected and read, it occurred to me that not a single card said what I really want to say to you.

You'll soon be 84 years old, Dad, and you and I will have had 55 Father's Days together. I haven't always been with you on Father's Day but I've always been with you in my heart.

You know, Dad, there was a time when we were separated by the generation gap. You stood on one side of the Great Divide and I on the other.

The Father-Daughter Duel shifted into high gear ( 檔位) when you taught me to drive the old Dodge and I decided I would drive the '54 Chevy whether you liked it or not. The police officer who sent me home, after you reported the Chevy stolen, didn't have much tolerance for a stub­born 16 year old, while you were so tolerant about it, Dad, and I think that was probably what made it the worst night of my life.

Our relationship greatly improved when I married a man you liked, and things really turned around when we began making babies right and left. Somewhere along the line, the generation gap disappeared. I suppose I saw us and our relationship as aging together, rather like a fine wine.

But the strangest thing happened last week. I was at a stop sign and I watched as you turned the corner in your car. It didn't immediately occur to me that it was you because the man driving looked so elderly and fragile behind the wheel of that huge car. It was rather like a slap in the face delivered from out of nowhere. Perhaps I saw your age for the first time that day.

I guess what I'm trying to say, Dad, is what every son and daughter wants to say to their Dad today. Honoring a father on Father's Day is about respect and sharing and acceptance and tolerance and giving and taking. It's about loving someone more than words can say, and it's wishing that never had to end.

I love you, Dad.

Love,

Jenny

1. How did Jenny probably feel on the night she was sent home by the police?

A. Frightened B. Guilty C. Nervous D. Disappointed

2.We can learn from the passage that Jenny and her father_________.

A. had a hard time understanding each other.

B. has been getting along very well.

C. are separated due to the generation gap.

D. kept in touch by writing to each other.

3. Why did Jenny feel strange when she saw her father last week?

A. She had never seen him driving so slowly before.

B. She didn't expect to meet with him there.

C. She had never realized his being old and weak

D. She seldom saw him driving that huge car

4. Jenny wrote his father this letter to _________

A. remind him of the early incident B. express her gratitude to him

C. say sorry for her being stubborn D. tell him about their conflicts

Dear Mom, Clear My Calendar

September is around the corner, and some of us are already complaining about summer’s end. But parents have a special reason to do so. The end of summer means the start of school. And these days, planning a young child’s schedule is a big challenge. The challenge is no longer finding activities to fill a child’s day; it is saying no to the hundreds of options available. Our mailbox is filled with brochures urging us to sign our kids up for classes from cooking to martial arts(武術(shù)).

Educators are themselves discouraged by the number of special classes that many children attend. In the name of “enrichment,” three-year-olds not only go to preschool in the morning but study French or gymnastics after lunch. One teacher tells of a four-year-old asking for help in the toilet before hurrying off to tennis. Another teacher says that children sometimes hold on to her at pickup time. What happened to unstructured time?

A generous explanation is that we enjoy giving children opportunities we never had. The truth however is that many parents have doubts about how much time they spend away from their families. And one way to reduce this guilt is to believe that time spent in these classes is somehow more beneficial to children than the time we know we should be giving them ourselves.

David Elkind, an expert on children, suggests that the 1960s gave birth to the belief that earlier is better. Parents hope that early music lessons, for example will build a child’s confidence. The truth, however, is that any time children are asked to do too much, too soon, they are at greater risk for feelings of failure.

A child’s time does not have to be planned to be meaningful. Remember the lazy days of summer? Some children sleep late and play with the kids across the street until it’s time to come home for dinner. However, with the majority of mothers working, fewer children enjoy that idle (空閑的) time now.

Come September, children across the country will finish a full day of kindergarten, only to attend an after-school program until 6 P.M., when a working mom or dad comes to take them home. That’s too much for a five-year old. Finances, of course, do limit some parents. But let’s be honest with ourselves – our own busy schedules, whatever they involve, are no excuse for burdening a young child’s.

1. The author holds that it’s a challenge to plan a schedule for a child mainly because _____.

A. a child’s schedule is too complex

B. activities suitable for kids are limited

C. parents are stuck in numerous choices

D. children always say no to parents’ advice

2. What the two teachers say in Paragraph 2 implies that _____.

A. children love to stay at school

B. they are popular with children

C. children dislike after-school classes

D. after-school classes are of poor quality

3. According to the author, what is the real reason for parents to send their children to after-school classes?

A. Parents want to make up for their own regrets.

B. After-school classes develop children’s potential.

C. Parents have doubt about their own ability to guide children.

D. After-school classes give parents an excuse for being absent.

4.Which of the following will the author probably agree with?

A. For children’s benefits, the earlier the better.

B. Children’s spare time should be carefully designed.

C. Idle time for children is becoming a thing of the past.

D. Parents should be forgiven if they have a good reason.,

Most of the people who appear most often and most gloriously in the history books are great conquerors and generals and soldiers, whereas the people who really helped civilization forward are often never mentioned at all. We do not know who first set a broken leg, or launched a seaworthy boat, or calculated the length of the year, or manured(施肥)a field; but we know all about the killers and destroyers. People think a great deal of them, so much so that on all the highest pillars (紀念柱) in the great cities of the world you will find the figure of a conqueror or a general or a soldier. And I think most people believe that the greatest countries are those that have beaten in battle the greatest number of other countries and ruled over them as conquerors. It is just possible they are, but they are not the most civilized.

　　Animals fight; so do savages (野蠻人); hence to be good at fighting is to be good in the way in which an animal or a savage is good, but it is not to be civilized. Even being good at getting other people to fight for you and telling them how to do it most efficiently －this, after all, is what conquerors and generals have done －is not being civilized. People fight to settle quarrels. Fighting means killing, and civilized peoples ought to be able to find some way of settling their disputes other than by seeing which side can kill off the greater number of the other side, and then saying that that side which has killed most has won. And it not only has won, but, because it has won, has been in the right. For that is what going to war means; it means saying that might is right.

　　That is what the story of mankind has on the whole been like. Even our own age has fought the two greatest wars in history, in which millions of people were killed or disabled. And while today it is true that people do not fight and kill each other in the streets －while, that is to say, we have got to the stage of keeping the rules and behaving properly to each other in daily life － nations and countries have not learnt to do this yet, and still behave like savages.

1.In the opening sentence the author indicates that ________.

　A. conquerors, generals and soldiers should not be mentioned in history books.

　B. history books focus more on those who helped civilization forward.

　C. those who truly helped civilization forward is rarely mentioned in history books.

　D. most history books were written by conquerors, generals and soldiers.

2.In the author’s opinion, the countries that ruled over a large number of other countries are

　A. certainly both the greatest and the most civilized

　B. neither the most influential nor the most civilized.

　C. possibly the most civilized but not the most powerful.

　D. likely the greatest in some sense but not the most civilized.

3. The meaning of “it means saying that might is right.”(The last sentence of Paragraph 2) is that ________.

　A. in a war only those who are powerful will win.

　B. those who are right should fight against those who are wrong.

　C. only those who are powerful have the right to go to war.

　D. those who fight believe that the winner is right and the loser wrong.

4. In the third paragraph, what the author wants to convey to us is that ________.

A. we have fought fewer wars but suffered heavier casualties.

B. modern time is not so civilized compared with the past.

C. our age is not much better than those of the past.

D. World War I and World War II are different from previous wars.

5. According to the passage, who helped civilization forward?

A. The pioneers in science and technology.

B. Conquerors and generals.

C. Those setting disputes by force.

The experts in military matters

6. This passage is most likely taken from an article entitled ________.

A. Who Should Be Remembered

　B. Civilization and History

　C. War and World Peace

D. Great conquerors in the world

科目：高中英語 來源：2016屆黑龍江省安達市高一下學期期中考試英語卷（解析版） 題型：閱讀理解

In the US, people prefer waiting for a table to sitting with people they don’t know. This means a hostess may not seat a small group until a small table is available, even if a large one is. If you are sitting at a table with people you don’t know, it is impolite to light up a cigarette without first asking if it will disturb them.

At American restaurants and coffee shops you are usually served tap (水龍頭)water before you order. You may find the bread and butter is free, and if you order coffee, you may get a free refill(重續(xù)).

Most cities and towns have no rules about opening and closing time for stores or restaurants, though they usually do make rules for bars. Especially in large cities, stores may be open 24 hours a day.

Serving in restaurants is often large; too large for many people. If you can’t finish your meal but would like to enjoy the food later, ask your waitress or waiter for a “doggie bag”. It may have a picture of a dog on it, but everybody knows you’re taking the food for yourself.

Tips are not usually added to the check. They are not included in the price of the meal, either. A tip of about 15% is expected and you should leave it on the table when you leave. In some restaurants, a check is brought on a plate and you put your money there. Then the waiter or waitress brings you your change.

1.Which statement is TRUE?

A. American people like sitting with people they don’t know.

B. Hostess always seats a small group at a large table.

C. American people never sit with people they don’t know.

D. American people would not light a cigarette if the people who sit at the same table mind their smoking.

2.What is served before you order?

A. Cold water. B. Butter. C. Coffee. D. Bread.

3.What do American people always do when servings are too large for them?

A. They take the food home with a doggie bag for their dogs.

B. They leave the food on the table and go away.

C. They take the food home with a doggie bag and enjoy the food later.

D. They ask the waitress or waiter to keep the food for them.
