题目内容

【题目】Butterflies are some of the most fascinating and beautiful insects in the world. Adult butterflies will live about 2 to 4 weeks. They use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry enemies.

Butterflies have large compound eyes(复眼), which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a sea of flowers than individual plants. Butterflies do not “see” colors such as red, green, and yellow, but they can sense sunlight, which indicates the direction the sun is shining, as well as ultraviolet light(紫外线), which is present on many flowers and guides butterflies to honey sources.

Butterflies have a very well-developed sense of smell, but it is not in their nose, since they don't have one. Sense receptors are located in their antennae(触角), feet, and many other parts of the body. They can help butterflies find their favorite flower honey food, and mates.

Butterflies' feet have sense organs that can taste the sugar in flower honey, letting the butterflies know if something is good to eat or not. Some females also carefully choose host plants by tasting to find appropriate places to lay their eggs. Adult butterflies feed their babies using a long tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.

Butterflies don't have ars. Instead they “hear” sounds through their wings by sensing changes in sound vibrations(振动).

Butterflies may possess senses we don't even know about yet, because their body structure is very different from ours, and therefore difficult to understand, when observed through our own human senses.

【1What can we learn from the 2nd paragraph?

A. Butterflies have good eyesight.

B. Butterflies can see in all directions and don't need to turn heads.

C. Butterflies are sensitive to bright colors including red and yellow.

D. Butterflies cannot sense the ultraviolet light.

【2How do butterflies hear sounds?

A. Using their feet to sense the vibration of things

B. Using their ears to listen directly

C. Using their wings to sense the sound vibrations

D. Using their antennae to judge the sound

【3Why do female adult butterflies carefully choose the host plants?

A. To find high-qualified honey.

B. To have a good place for living.

C. To make it easier for them to hide from the enemies.

D. To find a proper place for their eggs.

【4What does the last paragraph imply?

A. There’s a long way to understand butterflies well

B. Butterflies give great help to human beings

C. Butterflies are the most beautiful insects in the world

D. Butterflies possess more senses than humans

【5The text mainly focuses on ________.

A. butterflies' living habits B. butterflies' beauty

C. butterflies' daily activities D. butterflies' senses

【答案】

【1】B

【2】C

【3】D

【4】A

【5】D

【解析】试题分析:本文主要介绍了蝴蝶的几种感觉:视觉,嗅觉,听觉和触觉。在作比较中将几种感觉说得生动而明晰。虽然人类了解了蝴蝶的大致构造,但是由于蝴蝶与人类身体结构很不一样,故目前阶段的了解还是浅显的。对于蝴蝶的研究还有很长一段路要走。

【1】细节理解题。由第二段第一句话“Butterflies have large compound eyes, which allow them to see in all directions without turning their heads.”可知,蝴蝶有很大的复眼,所以它们能够不转头就看到所有方向。故选B。

【2】推理判断题。定位到第三段第一、二句。第一句说蝴蝶的嗅觉很灵敏,但是它们没有感触器官,因此触觉很不发达。Sense receptors are located in their antennae, feet, and many other parts of the body.第二句说明感觉受体很多,有触角、脚和身体的其他部位。而蝴蝶的翅膀也差不多就是整个身体。故选C,它们用翅膀感觉事物的震动。

【3】细节理解题。定位到第四段的第二句话Some females also carefully choose host plants by tasting to find appropriate places to lay their eggs.“一些雌性蝴蝶为了找到一个合适的地方产卵会通过仔细品尝来挑选寄主植物”易知雌性蝴蝶品尝寄主植物的目的就是为了找个合适的地方产卵。故选D。

【4】概括归纳题。最后一段开头谈到Butterflies may possess senses we don't even know about yet, because their body structure is very different from ours“蝴蝶也许还拥有我们不知道的感觉,因为他们的身体结构与我们人类的很不一样。”可知我们还不是很了解蝴蝶,对蝴蝶还需要很多的研究。故选A。

【5】主旨大意题。本文主要介绍了蝴蝶的几种感觉:触觉,听觉,视觉,嗅觉。同时又在这几种感觉中展开比较,说明因为有复眼,她们的视觉很广;嗅觉也很灵敏。但是听觉和触觉则其次。故选D。

【题目】It was Saturday. As always, it was a busy one, for "Six days shall you labor and do all your work" was taken seriously back then. Outside, Father and Mr. Patrick next door were busy chopping firewood. Inside their own houses, Mother and Mrs. Patrick were engaged in spring cleaning. Somehow the boys had slipped away to the back lot with their kites. Now, even at the risk of having Brother caught to beat carpets, they had sent him to the kitchen for more string(线). It seemed there was no limit to the heights to which kites would fly today.

My mother looked at the sitting room, its furniture disordered for a thorough sweeping. Again she cast a look toward the window. "Come on, girls! Let's take string to the boys and watch them fly the kites a minute."

On the way we met Mrs. Patrick, laughing guiltily as if she were doing something wrong, together with her girls.

There never was such a day for flying kites! We played all our fresh string into the boys' kites and they went up higher and higher. We could hardly distinguish the orange-colored spots of the kites. Now and then we slowly pulled one kite back, watching it dancing up and down in the wind, and finally bringing it down to earth, just for the joy of sending it up again.

Even our fathers dropped their tools and joined us. Our mothers took their turn, laughing like schoolgirls. I think we were all beside ourselves. Parents forgot their duty and their dignity; children forgot their everyday fights and little jealousies. "Perhaps it's like this in the kingdom of heaven," I thought confusedly.

It was growing dark before we all walked sleepily back to the house. I suppose we had some sort of supper. I suppose there must have been surface tidying-up, for the house on Sunday looked clean and orderly enough. The strange thing was, we didn't mention that day afterward. I felt a little embarrassed. Surely none of the others had been as excited as I. I locked the memory up in that deepest part of me where we keep "the things that cannot be and yet they are."

The years went on, then one day I was hurrying about my kitchen in a city apartment, trying to get some work out of the way while my three-year-old insistently cried her desire to "go park, see duck."

"I can't go!" I said. "I have this and this to do, and when I'm through I'll be too tired to walk that far."

My mother, who was visiting us, looked up from the peas she was shelling(去皮). "It's a wonderful day," she offered, "really warm, yet there's a fine breeze. Do you remember that day we flew kites?"

I stopped in my dash between stove and sink. The locked door flew open and with it a rush of memories. "Come on," I told my little girl. "You're right, it's too good a day to miss."

Another decade passed. We were in the aftermath (余波) of a great war. All evening we had been asking our returned soldier, the youngest Patrick Boy, about his experiences as a prisoner of war. He had talked freely, but now for a long time he had been silent. What was he thinking of what dark and horrible things?

"Say!" A smile sipped out from his lips. "Do you remember no, of course you wouldn't. It probably didn't make the impression on you as it did on me."

I hardly dared speak. "Remember what?"

"I used to think of that day a lot in POW camp (战俘营), when things weren't too good. Do you remember the day we flew the kites?"

【1Mrs. Patrick was laughing guiltily because she thought_________.

【题目】The Internet of Things (IoT) aims to get everything and everyone talking. Attaching sensors to “things”, such as cows, cars and refrigerator, and then assigning them unique IP addresses allow them to “talk” to the Internet. Of course, the IoT will involve much more than a handful of sensors. Networking company Cisco estimates that 50 billion Internet-connected devices and objects will

be sending over data by 2020.

Specific Benefits
The IoT will allow people to track things and processes like never before. Airplane manufacturers will be able to continuously track the condition of airplane parts, allowing them to do preventive maintenance and avoid costly downtime. Consumers could install smart meters in their homes to monitor energy usage and observe energy price changes in real time. That would allow people to adjust their habits and use electrical appliances during lower-priced hours.

Some Fears
Some critics fear that the IoT could end up being a fashion that people lose interest in over time. Having Twitter feeds on refrigerator doors may sound cool at first, but the attraction could fade as quickly as the excitement over last year’s smartphone! Other critics are doubtful that companies making Internet-connected appliances will provide long-term software updates. If that happens, a refrigerator or washing machine that should last 10 years or more could last two or three due to software that’s outdated.

A Positive Example
Early this year, owners of the Tesla Model S electric car received a recall notice alerting them to a charger plug needing to be fixed. Amazingly, owners of the Model S sat back while the company performed an “over the air” wireless update. Customers confirmed the update by tapping on the car’s touchscreen console to see that the Model S was running the latest software version. No trip to the dealer was required!
Perhaps Tesla’s remote fix is a sign of things to come. Someday soon, people’s lives might become a lot more efficient and convenient thanks to the IoT.

1How do researchers get everything and everyone talking?

A. By establishing the IoT and launching a handful of sensors.

B. By connecting sensors with them and appointing them unique IP addresses.

C. By communicating with them all the time through the IoT.

D. By sending people to track them day and night and collect useful data.

2According to the article, which of the following is NOT TRUE?

A. IoT can help people do preventive maintenance and save money.

B. IoT can help people monitor energy usage and observe price changes timely.

C. IoT can help people adjust their habits and use electrical appliances more smartly.

D. IoT can help people investigate things and update a lot of important data.

3What else do critics worry about the IoT besides its probably ending up being a fashion?

A. People will lose interest in it as quickly as the thrill over last year’s smartphone.

B. Refrigerators and washing machines will be replaced by other devices in a few years.

C. Whether related companies will provide long-term software updates or not.

D. The software provided by companies will be outdated easily and quickly.

4According to the passage, when owners of the Tesla Model S electric received a recall notice, they ______.

A. just waited in the car while the maintenance is being done through wireless update

B. were required to go to the nearest 4s store to make some adjustments or repairs

C. could definitely depend on the IoT to send them the charger plug to be fixed

D. had to confirm the update with the help of the equipment provided by the company

【题目】 “The U.S.Food and Drug Administration(FDA)is considering to put stricter limits over tanning salons(晒黑廊)and wants to ban anyone younger than 18 years of age from using a tanning bed,”an advisory panel(专家团)announced last week.

The panel is calling for tighter controls on the industry such as requiring teenagers to get the approval from their parents before using tanning beds or limiting the use of artificial tanning to a certain age.“Given the absence of any demonstrated benefits,I think it is an obligation for us to ban artificial tanning for those under 18,”said panelist Dr.Michael Olding.

Along with a possible ban for teenagers,the panel also recommended that visible warning labels should be placed either on the tanning machines or in the salons in order to caution tanners of the possible dangers.In addition,the committee decided that stricter regulations and classifications were critical to make the machines safer.At this time the machines are categorized as FDA Class 1 devices,the ones that are least likely to cause harm.In case the FDA decided to change their classification from Class 1 to Class 2,as advised by the panel,the FDA could limit the levels of radiation the machines emit.Class 2 devices include Xray machines and powered wheelchairs.

Getting a tan,whether from a tanning bed or the sun,increases the risk of developing skin cancer.Last year,the World Health Organization's International Agency for Research on Cancer (IARC)declared tanning beds as “carcinogenic(致癌的)to humans”.It was discovered that young individuals in their teens and 20s who use tanning beds on a regular basis have a 75per cent higher risk of suffering from melanoma(黑素瘤),the deadliest form of skin cancer.According to the American Cancer Society,melanoma accounted for nearly 69,000 cases of skin cancer in 2009 and will account for most (about 8,650)of the 11,590 mortality cases due to skin cancer each year.

【1】According to the passage,what measures will U.S.FDA most probably take?

A.Banning tanning salons.

B.Posing heavier tax over tanning salons.

C.Having tighter controls over tanning salons.

D.Limiting the number of tanning salons in every state.

【2】Which of the following suggestions for making tanning salons safer is NOT mentioned?

A.Visible caution.

B.Setting age limit.

C.Professional personnel.

D.Parental approval for teenagers.

【3】What does the writer want to express in the last paragraph?

A.Tanning in one's youth may mean death.

B.Tanning in the sun is safer than on the tanning bed.

C.People should get tanned without getting melanoma.

D.Getting tanned is only a good idea for those above thirty years old.

【4】What will most probably happen,if the advisory panel's suggestions are adopted and put into practice?

A.Fewer people will suffer from skin cancer.

B.Tanning salons will have more customers.

C.Getting a tan in a tanning salon will cost less.

D.Parents will be more anxious about their tanning children.
