THE idea came to Ralph Liedert while he was sweating in the Californian sunshine, having been standing with his daughter for over an hour in a queue for a ride at Disneyland. What, he thought, if his T-shirt had a cooling system he could turn on, at the tap of a smart phone app, when he needed it. Luckily, Mr Liedert does have the means to make the dream reality, for he works at the VTT Technical Research Centre of Finland, as one of a team there studying the rapidly growing field of microfluidics (微流控技术).

Cooling vests already exist (used by racing drivers, motorcyclists and people who work in hot conditions). But the tubes through which the cooling water is being pumped, and the vests’ need to be connected to outside units that cool this water, make them huge and clumsy. Mr Liedert thought VTT’s microfluidics department could do things better.

As its name suggests, microfluidics is the art of building devices that handle tiny amounts of liquid. Inkjet-printer cartridges (喷墨打印机墨盒) are a familiar example. Less familiar, but also important, are “labs-on-a-chip” (芯片实验室). These are tiny analytical devices that transport fluids such as blood through channels half a millimetre or less in diameter (直径), in order to carry them into what holds analytical reagents (试剂). Sensors, then detect the resulting reactions and provide an instant analysis of a sample (样本). Designing labs-on-a-chip is the VTT microfluidics department’s day job. One of its chips, for example, can tell whether water is affected by the bacteria that cause Legionnaires’ disease.

The department’s biggest contribution to the field, though, is to have developed a way of printing microfluidic channels onto large rolls of thin, flexible plastic. It works by passing the plastic between two heated rollers, one of which contains raised outlines of the required channels. As the rollers squeeze the plastic they create a pattern of channels into one surface. A second plastic film is then melted over the top as a cover. This process might, thought Mr Liedert, be suitable for printing a microfluidic cloth that was thin enough and pleasant enough to wear as a cooling vest.

The group’s first model showed that such a material could indeed be made and used to circulate cooled water. They are also looking at ways the water being circulated through the microchannels might be cooled. They have identified two. One uses a small heat-exchanger, the details of which they are keeping secret at this stage. The other employs evaporation (蒸发). It thus works in the same way that heat from circulating blood is removed by the evaporation of sweat.

Whichever cooling system is applied, the electronics needed to power and control it would be shrunk into a small package contained on the back of the vest. This could be operated by hand or, as Mr Liedert originally envisaged in his Californian queue, by a wireless link to a smart phone. Moreover, what can cool down can also, if run in an opposite way, warm up. In Finland, where winter temperatures fall as far as -50°C, that might be the technology’s killer app.

1.Microfluidics has been used in ______.

A. racing cars B. printing industry

C. testing material D. clothing industry

2.We can learn from the passage that ______.

A. VTT is a company which mainly works on the research into microfluidics

B. the new cooling vest of VTT will be smaller and work more effectively

C. the technology of microfluidics may have a positive effect on medical science

D. heat-exchanger as well as the way of evaporation will be used to cool the wearer

3.______ plays the key role in making the new cooling vest.

A. The special cloth B. The cooling system

C. The tiny liquid D. The wireless link

Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of diet plan.

Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious(难为情)when they’ re in poorly lit places----and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.

Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us feel less hungry. So when it’s time to repaint, go blue.

Don’ t forget the clock----or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you’ re at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one ,total intake (摄入) jumps by 14 percent. And we’ ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

1.The text is especially helpful for those who care about_______.

A. healthy diets B. house buying

C. their body shape D. their home comforts

2.A home environment in blue can help people_________.

A. reduce food intake B. digest food better

C. regain their appetites D. burn more calories

3.What are people advised to do at mealtimes?

A. Use smaller spoons. B. Turn down the lights.

C. Eat quickly. D. Play fast music.

4.What can be a suitable title for the text?

A. Is Your Home Environment Relaxing?

B. Is Your House Making You Fat?

C. Ways of Serving Dinner

D. Effects of Self-Consciousness

The Cuban iguana is a species of lizard（蜥蜴） of the iguana family. It is the largest of the West Indian rock iguanas, one of the most endangered groups of lizards. This species with red eyes and a thick tail is one of the largest lizards in the Caribbean.

The Cuban iguana is primarily herbivorous; 95% of its diet consists of the leaves, flowers and fruits from as many as 30 plant species, including the seaside rock bush and various grasses. However, Cuban iguanas occasionally consume animal matter, and individuals have been observed eating the dead flesh of birds, fish and crabs. The researchers wrote that quite a few people on Isla Magueyes could have caused this incident.

The Cuban iguana is distributed throughout the rocky southern coastal areas of mainland Cuba and its surrounding islands with a wild population booming on Isla Magueyes, Puerto Rico. It is also found on the Cayman Islands of Little Cayman and Cayman Brac, where a separate subspecies occurs. Females guard their nest sites and often nest in sites half destroyed by Cuban crocodiles. To avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti（仙人掌）.

In general the species is in decline, more quickly on the mainland than on the outlying islands. One of the reasons for their decline is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts on the beaches where the animals prefer to build their nests. Although the wild population is in decline, the numbers of iguanas have been sharply increased as a result of captive-breeding（圈养）and other conservation programs.

1.The underlined word "herbivorous" （Paragraph 2） probably means .

A. dangerous B. gentle

C. plant-eating D. flesh-eating

2.Why does the Cuban iguana build its nest near prickly-pear cacti?

A. To keep itself cool.

B. To get the food easily.

C. To stay away from people.

D. To avoid crocodiles' attack.

3.How many reasons are mentioned for the habitat destruction?

A. Two. B. Three. C. Four. D. Five.

4.What's the author's purpose of writing the text?

A. To give us a brief introduction to the Cuban iguana.

B. To show he is concerned about the Cuban iguana.

C. To explain reasons for the Cuban iguana's decline.

D. To draw people's attention to the endangered Cuban iguana.
