14.Keeping an Eye on the Weather
Weather forecasters don't just look out of the window to prepare the report you see on TV or hear on the radio.They use a high-tech weather information network located all over-and above
-the globe.Satellites orbit Earth all the time.Planes and balloons go up daily to collect data.Weather stations in almost every country on the earth contribute data.

As you've noticed,forecasters sometimes make mistakes.A forecast is only a prediction.It is based on what's happening now.However,nature doesn't always follow a predictable pattern,so a forecast is only an educated guess,not a certainty.
Weather satellites remain in fixed positions 22,000miles above the equator (赤道).Together,their cameras can photograph the entire earth,except the poles.Other satellites follow north-south and south-north routes from pole to pole.
The long tails of weather balloons are equipped with radiosondes,which measure temperature,air pressure,and humidity in the atmosphere.Some balloons can reach as high as 90,000feet to collect data.

Weather monitoring equipment is attached to airplanes.These planes can fly directly into storms to take measurements.
About 10,000weather stations around the world send reports every three hours to 13weather centers operated by the World Meteorological Organization (世界气象组织).

Probably the most familiar piece of weather equipment is the weather vane.It's certainly one of the oldest.Weather vanes have been around since the ninth century.They indicate the direction the wind is blowing.
Radar equipment sends signals into clouds.These signals are then changed into images on radar screens,allowing meteorologists to track storms.
Other stations float at sea and send data to satellites.
64.Why do forecasters sometimes make mistakes?(不多于9个词)Because nature doesn't always follow a predictable pattern
65.What are measured by weather balloons equipped with radiosondes?(不多于9个词)
Temperature,air pressure and humidity
66.What does the weather vane indicate?(不多于6个词)The direction of the wind
67.What does the passage mainly talk about?(不多于6个词)Weather information network.

分析 本文为说明文.介绍了预报天气的一些设备,如卫星,预报气球等.

解答 1.Because nature doesn't always follow a predictable pattern. 细节题.第三段"nature doesn't always follow a predictable pattern"提及了天气预报有时出错的原因在于,大自然有时候不按照预测的来.
  2.Temperature,air pressure and humidity.细节题.在weather balloons 这段提到了主要测量的项目有:"which measure temperature,air pressure,and humidity".
  3.The direction of the wind. 细节题.在weather vane 这段里提到了:They indicate the direction the wind is blowing.
  4.Weather information network.主旨概括题.根据全文的内容以及图片小标题,推出大意为介绍天气预报信息的网络系统.

点评 阅读表达主要考查学生对文章理解能力以及处理信息的能力.要在全面理解大意基础上,对细节进行整合重组,控制字数.

19.Cold weather can be hard on pets,just like it can be hard on people.Sometimes owners forget that their cats are just as used to the warm shelter (住所) as they are.Some owners will leave their animals outside for a long period of time,thinking that all animals are used to living outdoors.This can put their pets in danger of serious illness.There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad.If you have to take them out,stay outside with them.When you're cold enough to go inside,they probably are too.If you must leave them outside for a long time,make sure they have a warm,solid shelter against the wind,thick bedding,and plenty of non-frozen water.
If left alone outside,dogs and cats can be very smart in their search for warm shelters.They can dig into snow banks or hide somewhere.Watch them closely when they are left outdoors,and provide them with shelter of good quality.Keep an eye on your pet's water.Sometimes owners don't realize that a water bowl has frozen and their pet can't get anything to drink.Animals that don't have clean and unfrozen water may drink dirty water outside,which may contain something unhealthy for them.

8.What do we learn about pets from Paragraph 1?D
A.They are often forgotten by their owners.
B.They are used to living outdoors.
C.They build their own shelters.
D.They like to stay in warm places.
9.Why are pet owners asked to stay with their pets when they are out in cold weather?A

A.run short of clean water
B.dig deep holes for fun
C.dirty the snow nearby
D.get lost in the wild
11.What is the purpose of this text?B

6.Neil Armstrong,the first man ever to set foot on the moon,is best remembered by his words"That's one small step for (a) man,one giant leap for the mankind".Once,in an interview with his son,he said it was difficult to watch a sci-fi movie with his dad,because Armstrong would keep complaining about how unrealistic their vision of space were.
In fact,even the Oscar-winning Gravity,described as"the most realistic space movie ever"by Forbes,is not 100 percent faithful to reality.Here is part of a former NASA astronaut-Garrett Reisman's movie review.
On the whole,it's a great movie.But the question that most people want me to answer is how realistic it was.
In general,sci-fi movies are usuallyfar-fetched.So it's amazing how many things Gravity gets right.The danger of space debris(残骸)is very real.There are currently more than 600,000 pieces of debris larger than 1 cm orbiting Earth and they pose a great risk to spacecrafts.However,in the movie,astronauts can see the debris coming and quickly seek shelter.In reality,debris can travel at 20 times the speed of sound,which means that if you can see it,it's already too late to hide.
Another huge error was-there was absolutely no reason for the male astronaut Matt Kowalski to sacrifice himself!!He lets go of the hand of his female partner,Ryan Stone,and drifts away into space.In reality,Kowalski wouldn't have flown away when Stone let go of his hand.Instead,he would have just stayed floating in that spot.
In the movie,Stone travels from the Hubble Telescope to the International Space Station and then to the Chinese Space Station Tiangong,where she finds an escape vehicle to take her back to Earth.But this is actually the biggest error in the movie.The Hubble,the International Space Station and a Chinese space station are not neighbors.Getting from one to the other requires so much energy that not even space shuttles had enough fuel to do it.In addition,space stations travel in different orbits,and they travel quickly.And it would be physically impossible to get from one to the other.
There are other,more minor details that are just unrealistic.For example,Stone doesn't wear a cooling garment(降温服)under her spacesuit to protect herself from the heat in space.
…Yes,I could go on and on about all the things Gravity got wrong.But who cares?All of these inaccuracies were done to help advance the plot or to add drama to the films.This is entertainment,not a documentary.
28.The purpose of the first paragraph is toB.
A.introduce the famous American astronaut Neil Armstrong
B.show that sci-fi movies are often considered unrealistic by astronauts
C.introduce why Gravity is the most realistic space movie ever
D.tell people not to believe everything they see in sci-fi movies
29.The underlined word"far-fetched"can best be replaced by"A".
A.unlikely to be true                    
B.difficult to understand
C.easy to mislead people                
D.unpopular with astronauts
30.Which of the following situations would agree with the laws of physics in space according to the passage?C
A.Astronauts collecting flying space debris
B.Astronauts wearing only T-shirts under their spacesuits
C.Astronauts staying afloat where they are after they part with a spaceship
D.Astronauts performing a space walk from the Hubble Telescope to the International Space Station
31.We can infer from the passage thatD.
A.Garrett Reisman doesn't think highly of the movie Gravity
B.directors of sci-fi movies usually don't care much about minor details
C.the shooting of space documentaries and sci-fi movies involve totally different skills
D.Garrett Reisman believes that sci-fi movies don't need to be totally faithful to reality.

4.Some 30,000years ago,artists who lived in caves in Europe painted pictures of the animals around them:panthers,hyenas,rhinos,cave lions,mammoths and other creatures which have been extinct for a long time.The paintings were highly realistic.Some even showed movement.
The artwork,more than a thousand drawings,is considered the oldest group of human cave drawings which have ever been discovered.They were preserved because the cave was sealed--closed off--for more or less 23,000years.
Fast forward to December 18,1994,a group of French cave scientists were exploring caves in southern France.Jean-Marie Chauvet,who led the group then,describes the process of discovering the cave paintings."At that time I was in the front,Eliette just walked behind me,Christian behind.Eliette said she saw two marks made with red ochre and she said,‘They came here.'And at this very moment everything began.The drawings and everything linked to the parietal art (壁画).That is where it started."
Cave art expert Jean Clottes reviewed the paintings."I was amazed at the number of paintings there were and paintings of their quality and particularly in front of the panel of the horses."
Scientific analysis confirmed the prehistoric date of the artwork.Studies showed the drawings were created tens of thousands of years ago,before human history was written.The United Nations'cultural agency UNESCO lists the cave as a World Heritage Site.They say that the drawings form a remarkable expression of early human artistic creation of grand excellence and variety.
The Chauvet Cave has been named after the explorer who first entered it.However,its environment and drawings are too fragile to be visited by human beings.So the cave is closed,and only people there for scientific purposes can go inside and see the artwork.
However,French authorities asked experts to create an exact copy of the cave,called Pont d'Arc Cavern.The copy,which we also call replica,cost more than 59million dollars to build.It opened at the end of April in France.
Pascal Terrasse is the president of the cavern.He says everyone will be able to experience the thrill of looking at drawings made by the first humans in Europe.He says the place is magic because it is done so well.Authorities say they think as many as 400.000people will be allowed to visit Pont d'Arc Cavern every year.

41.According to the passage,the first scientist to enter the cave wasD.
A.Christian      
B.Eliette      
C.Clottes      
D.Chauvet
42.According to Jean Clottes'words in Paragraph 4,the paintings in the cave wereB.
A.abstract      
B.superior      
C.creative      
D.inspiring
43.Which of the following statements is TRUE about the Chauvet Cave?C
A.It was closed off for more than 30,000years.
B.It is thought to be the origin of modern parietal art.
C.The environment and artwork there are very easy to damage.
D.The majority of drawings there are about the extinct animals.
44.Who can pay a visit to the Chauvet Cave nowadays?A
A.People who do scientific research.
B.Scientists who found the cave first.
C.Officials protecting historical heritage.
D.Scientists from the United Nations.
45.The purpose of creating Pont d'Arc Cavern is toC.
A.show admiration for the earliest artists in Europe
B.arouse visitors'awareness of protecting ancient art
C.offer visitors chances to view the wonderful artwork
D.collect money for the perseverance of the Chauvet Cave.
