A warm blanket is the ideal sleep aid for a freezing winter night. The right blanket can warm your bones but the wrong one can affect your sleep. I asked experts for advice on picking the perfect blanket for a good night’s sleep. Here’s what they told me.
When it comes to sleep temperature, experts recommend following the principle: not too cold, not too hot, but just right. “People seem to sleep best at temperature between 62 and 70 degrees F,” says Dr. Alice Hoagland. When the surrounding temperature falls too low, it can rouse you from sleep. A good blanket helps drive the coldness away.
At the other extreme, overheating yourself can affect your sleep as well. “Core body temperature typically drops during the first four hour’s of sleep,” says Dr. Hoagland. This decline in body temperature helps you fall asleep and stay asleep.
“In medical care, weighted blankets are one of our most powerful tools for helping people who are anxious, upset, and possibly losing control,” says Dr. Karen Moore. These special blankets are filled with weighted pellets. Weighted blankets are also marketed for general use as an aid to sleep and relaxation. Like a firm hug, weighted blankets help us feel safe.” This is the reason why many people like to sleep under a blanket even in summer.
“If you want to try this type of blanket, the best weight depends on your body size and personal preference. However, 15 to 30 pounds is typical for adults,” Moor says. She adds that weighted blankets are not recommended for those recovering from surgery.
“People can also have serious preferences for a particular blanket,” says Dr. Hoagland. “Regularly using a favorite blanket for sleep can help to develop a conditioned response so that sleep is quicker.” In fact, many sleep centers ask patients to bring their own blanket and pillow from home, which helps them fall asleep more easily.

China needs to set absolute restrictions on greenhouse gas emissions(釋放) if it is to fulfill its aim to set up a carbon market over the next five years, a cabinet office think tank said in a paper.
“It is only under an absolute emissions cap that carbon emission permits will become a scarce resource and possess the qualities of a commodity,” the State Council?s Development and Research Center said in a paper in Seeking Truth, a magazine published by the ruling party.
China has traditionally baulked(猶豫) at the idea of emissions caps either on a regional basis or for industrial sectors, invoking a key Kyoto protocol principle that puts most of the burden of cutting green-house gases on developed countries.
China, the world ‘s biggest emitter of greenhouse gases, has also been under external pressure to make stronger commitments in the battle against global warming .The country has been the biggest beneficiary(受益人) of the Clean Development Mechanism, a UN-backed scheme that allows industrialized countries to meet their CO2 reduction targets by purchasing certified emission reductions or CERs from low-carbon projects launched in developing nations.
However, the European Union, the biggest buyer of CERs, has said it will not accept CERs generated by Chinese projects once the first phase of its Emissions Trading Scheme ends in 2012, though projects already registered will remain valid.
【小題1】 What does China hope to do in the next five years?
A.to cut its emissions by 45% |
B.to set up a carbon market |
C.to have lower emissions than other countries |
D.to increase both emissions and production |
A.they care about the environment |
B.emissions harm people’s health |
C.of pressure from other countries |
D.they want more profit for their factories |
A.Countries can buy the right to produce as much carbon emissions as they like. |
B.All countries are required to set a carbon emissions cap and can then get certificates on how developed their environmental programme is. |
C.Developed countries are allowed to produce more emissions than industrial countries. |
D.Developed countries can buy the right to produce more carbon emissions from developing countries that produce less. |
A.Air pollution is still increasing the problem of climate change all over the world. |
B.China is still resisting cutting emissions as it is necessary for the manufacturing industry. |
C.China believes that it is free from meeting international standards on emissions. |
D.China will need to cut its emissions in the near future in order to keep up with the international community |

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.
【小題1】We can infer from the text that humans and animals ____.
A.depend on one sense in choosing food |
B.a(chǎn)re not satisfied with their food |
C.choose food in similar ways |
D.eat entirely different food |
A.A white butterfly. | B.A small bird. |
C.The bear. | D.The fox. |
A.the season changes |
B.the food color changes |
C.they move to different places |
D.they are attracted by different smells |
A.food is chosen for a good reason |
B.French and British food is good |
C.some people have few choices of food |
D.some people care little about healthy diet |
A.Why choosing the right food is important. |
B.How to choose the right food. |
C.The right amount of food for a person. |
D.Vegetables matter more than meat and sugar. |

For the people living in the Nile Basin, the river is their life.This 6,825 km waterway, whose watershed(流域)covers three million square kilometers, flows through mountains ,woodlands, lakes and deserts.Its potential for fishing, tourism and shipping is great—but so are its challenges.
Water shortage , already serious in Egypt and Sudan , will soon influence several other countries in the watershed as well.Today, about 160 million people depend on the Nile River for their living.Within the next 25 yeas ,the district's population is expected to double, adding to the demand brought about by growth in industry and agriculture.The frequent drought(干旱)adds to the urgency.
Water quality is also a problem.Precious soil is washed out to sea.Wastes from industry and agriculture create pollution.Higher concentrations of salt influence irrigated soils.Water-borne diseases continue unchecked.In areas where it's hot and damp, water hyacinths choke off(阻止) lakes, dams and other sections of the river, making it difficult for fishing and other businesses to move forward.
Native people along the narrow area of farmland have watched the sand move closer day by day.They’ve seen the river change course, and their only source(來源) of water thickened with mud.They’re very poor and have few choices.
But a new program, the Nile Basin Initiative (NBI), is offering very practical assistance.The program is more than just a water-management project.It’s a plan for the social and economic development of a vast district: it concentrates on the needs of the poorest of the poor and the environment that supports them.
These are whole ecosystem problems, calling for united solutions.Half the Nile Basin's countries are among the world's poorest nations;yet, somehow, they must find the resources, skills and political will to overcome these challenges.
【小題1】What are the great challenges the Nile Basin faces?
A.The development of shipping industry. |
B.Over fishing of native people. |
C.Water shortage and water quality. |
D.Increasing population and tourism. |
A.plants | B.a(chǎn)nimals | C.rocks | D.salts |
A.preventing water pollution |
B.improving living condition of the poor |
C.changing the river course |
D.preventing land from becoming desert |
A.People’s Life in Egypt and Sudan |

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技術(shù)). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(細胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs ( The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.)
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.
【小題1】According to the passage, human death IS now mainly caused by____.
A.diseases and aging | B.a(chǎn)ccidents and war |
C.a(chǎn)ccidents and aging | D.heart disease and war |
A.medicine | B.the Internet | C.brain cells | D.human organ |
A.heart disease will be far away from us |
B.human brains can decide the final death |
C.the basic materials of cells will last forever |
D.human organs can be repaired by new medicine |
A.human life will not last more than 120 years in the future |
B.humans have to take medicine to build new skin cells now |
C.much needs to be done before humans can have a longer life |
D.we have already solved the technical problems in building new cells |
A.Aging | B.Accidents | C.Cancer | D.Heart disease |

The United States is full of cars. There are still many families without cars, but some families have two or more. However, cars are used for more than pleasure. They are a necessary part of life.
Cars are used for business. They are driven to offices and factories by workers who have no other way to get to their jobs. When salesmen are sent to different parts of the city, they have to drive in order to carry their products. Farmers have to drive into the city in order to get supplies.
Sometimes small children must be driven to school. In some cities school buses are used only when children live more than a mile away from the school. When the children are too young to walk too far, their mothers take turns driving them to school. One mother drives on Mondays taking her own children and the neighbors' as well. Another mother drives on Tuesdays, another on Wednesday, and so on. This is called forming a car pool. Men also form car pools, with three or four men taking turns driving to the place where they all work.
More car pools should be formed in order to put fewer cars on the road and use less gas. Too many cars are being driven. Something will have to be done about the use of cars.
【小題1】The United States is filled with cars, but .
A.not every family has a car |

Expensive and new gloves allow chatterboxes(話匣子)to take the term “handsfree” to a new level—by talking into them as they make a call. The gloves are known as “Talk to the Hand” and cost £1,000 a pair. They fixed a speaker unit into the thumb and a microphone into the little finger that can be connected to any mobile handset using Bluetooth.
Artist Sean Miles designed the new gloves that double as a phone in part of his project that shows the possibilities of gadget recycling. He uses outdated gloves and combines them with parts from mobile handsets recycled through O2, which commissioned(承擔(dān))the project. Mobile phone users will be able to keep their hands warm while they chat without taking their phones out of their pockets or handbags.
Mr Miles designed two pairs of the new gloves—one in pink and the other in brown and yellow. They will appear in an exhibition this July and visitors will be able to win the gloves. If demand is high, they will then be produced on a larger scale. O2 Recycle, which backed the project, estimates that there are already 70 million unused mobile handsets in the UK. The service pays up to £260 to those who recycle gadgets including phones, handheld consoles, MP3 players and digital cameras.
Designer Sean Miles hopes his work will get people thinking about recycling. The 41-year-old said, “I hope that my ‘Talk to the Hand’ project will get people to think again about the waste created by not recycling gadgets. If a few more people recycle their gadgets rather than send them to trash, I think this project will have fulfilled its aim.”
Bill Eyres, head of O2 Recycle, urges people to recycle their phone responsibly. He said, “There’s a pressing need for all of us to look at outdated handsets, and all the gadgets that we move on from or upgrade each year. Whether they are consoles or cameras, we should think of them as a resource that we need to recycle responsibly rather than throw them away.”
【小題1】The underlined word “O2” in Paragraph 2 is probably the name of ______.
A.a(chǎn)n artist | B.a(chǎn) company | C.a(chǎn) mobile | D.a(chǎn)n exhibition |
A.in the exhibition |
B.from Mr Miles |
C.when they are mass produced |
D.a(chǎn)fter they recycle the gadgets |
A.promote the technology of IT |
B.enable people to talk to their hands |
C.raise people’s awareness of recycling |
D.a(chǎn)ttract visitors’ attention in the exhibition |
A.New mobiles that are fashionable. |
B.Outdated handsets that are upgraded. |
C.Outdated gadgets that can be used for recycling. |
D.New gloves that can be used for making phone calls. |

The smallest animal with a backbone(脊椎) known to science, a fish from the carp family, has been discovered in the peat swamps (沼澤)of Indonesia. Mature(成熟的)females of the fish species (種類)Paedocypris reach just 7.9mm in length.
The species was discovered in the highly acidic (酸性的) peat swamps of the Indonesian island of Sumatra by a team led by Ralf Britz, a zoologist at the Natural History Museum in London.
“This is one of the strangest fish that I’ve seen in my whole career,” Dr Britz said. “It’s tiny, and it lives in acid. I hope that we’ll have time to find out more about them before their habitat disappears completely.”
The species lives in dark tea-colored swamp waters, which are 100 times more acidic than rainwater. Although these swamps were once thought to be inhabited by very few animals, recent research has shown that they are home to a highly different range of species that occur nowhere else.
The peat swamps were damaged by forest fires in 1997, and are also threatened by agriculture. The scientists behind the discovery said that several populations of Paedocypris had already been lost.
“Many of the peat swamps we surveyed(調(diào)查)throughout South-East Asia no longer exist,” Dr Britz said. “Populations of all the miniature(微型的)fish of peat swamps have decreased or disappeared.”
Details of the discovery are published today in the journal Proceedings of the Royal Society of London, Series B.
【小題1】64.Which of the following would be the best title for the passage?
A.The Strangest Fish |
B.Acidic Peat Swamps |
C.Strange Species |
D.The Smallest Backbone Animal |
A.It lives in highly acidic rainwater. |
B.The species lives in the acidic waters of dark tea-coloured swamps. |
C.It was put in the Natural History Museum in London. |
D.Its habitat disappears completely. |
A.many places where these animals lived have been damaged |
B.the population of the specieshas increased |
C.there are many animals in the acidic peat swamps today |
D.a(chǎn)griculture doesn’t affect the living space of these animals |
A.the habitat will be more after a period of time |
B.many peat swamps that they surveyed have already survived |
C.he wants to find more miniature fishes before their habitat disappears |
D.he wants to have further research |

The octopus’s(章魚)reputation as a human-killer isn’t simply an exaggeration(夸張)—it is a total myth. The octopus can indeed be a deadly hunter, but only of its natural victims. Some shellfish(殼類動物)and an occasional sick or incautious fish have reason to be frightened of this multi-armed hunter, but a person is much too large to interest even the biggest octopus. Even the largest among octopi is much smaller than most people imagine. Far from being large enough to swallow a ship, as monster octopi in movies have been known to do, the largest octopus, found on the Pacific coast, weighs around 110 pounds and grows to no more than ten feet in width.
The hard, parrot-like beak(喙)of an octopus is not used for attacking deep-sea divers, but for cutting open shellfish. Indeed, the octopus possesses such a tiny throat that it cannot swallow large pieces of meat. Instead, it feeds by pouring digestive juices into its victims, and then sucking up the soupy remains. A shellfish that finds itself in the grasp of an octopus has only a short time to live. But human beings are perfectly safe. Still, people rarely care to go close enough to these careful creatures to get a good look at them.
【小題1】This passage is mainly about .
A.the horrors of the octopus |
B.the largest octopus in the world |
C.octopi and their behavior |
D.the octopus’s deadly hunting method |
A.people have unreasonable fears about the octopus |
B.the octopus is not interested in human beings |
C.the octopus is afraid of human beings |
D.the octopus is a very cruel sea animal |
A.Octopi. | B.Shellfish. | C.Fish. | D.The victims. |
A.a(chǎn)ttacking deep-sea divers | B.cutting up large pieces of meat |
C.cutting open its victims | D.defending itself |
A.the octopus is not dangerous to man |
B.people often fear creatures that are not dangerous to them |
C.the octopus only hunts its natural victims |
D.things described in movies are not to be believed |
