It’s interesting that the arrival of snow has effect on people in different countries. For some countries it is an important happening to celebrate each year, while for others a catastrophe(灾害) or even a wonder.

　But there are countries between these two kinds that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year. Britain is one of them, for which the arrival of snow quite simply causes problems. Within hours of the first snowfalls, however light, roads are blocked, trains and buses have to stop in the middle of the way. Normal communication is affected as well: telephone calls become difficult and the post immediately takes more time than usual. And almost within hours, there are also certain shortages----bread, vegetables and other things-----not because all these things can no longer be produced or sent to shops, but mainly because people are frightened and go out and store up with food and so on…just for fear that something bad should happen.

　But why does snow have this effect? After all, the Swiss, the Austrians and the Canadians don‘t have such problems. It is simple because there is not enough planning and preparation. We need money to buy equipment to deal with snow and ice. To keep the roads clear, for example, requires snow-ploughs(扫雪机) and machines to spread salt. The reason why a country like Britain does not buy snow-ploughs is that they are used for a few days in any one year, and the money could be more useful in other things such as hospital, education, helping the old and so on..

1.According to the writer, Britain is a country ________.

　2.After a few hours’ snowing there are often some shortages of food because ______.

　A. shops have closed down B. people buy as much as they can

　B. farmers cannot produce any more D. people eat more vegetables in winter

　3.The words "two kinds" in the passage mean the countries ______.

Some people sit outside for hours without getting bitten by mosquitoes, but it always seems like you’re being eaten alive within minutes of stepping outdoors.

If this is you, you’re not alone. According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes’ mouths water?

A popular myth claims that mosquitoes prefer certain blood types, but the fact is that they simply can’t tell what your blood type is from a faraway place. Jonathon Day, a professor of medical entomology (昆虫学) at the University of Florida in the US, told NBC it’s not complicated. “The two most important reasons a mosquito is attracted to you have to do with sight and smell.”

Mosquitoes are especially active in the late afternoon. While flying along, they use their sense of smell to find possible targets. They find victims (攻击对象) by smelling the carbon dioxide (CO2) breathed out by humans and animals. That’s why you commonly find them in crowded streets and parks.

Joop van Loon, an entomologist at Wageningen University in the Netherlands, told Live Science, “Mosquitoes start orienting (使......朝向) themselves to carbon dioxide and keep flying upwind as they sense higher concentrations (浓度).”

As a result, people who simply exhale (呼出) more of the gas over time – generally, larger people – have been shown to attract more mosquitoes than others. “This is why kids don’t get bitten as much ... as adults,” US professor Ted Rosen told Science Alert.

This love for CO2 can also put pregnant women at increased risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren’t pregnant.

In addition to carbon dioxide, the color of the clothes you wear also plays a role in attracting mosquitoes.

According to Live Science, mosquitoes can lock onto targets from up to 50 meters away. At this distance, what we wear has a huge effect. Due to their vision (视觉), people wearing dark colors are more likely to become targets.

Being bitten by mosquitoes is annoying, but don’t worry. Some simple tips can help ward them off. Scientists recommend that we use insect repellent (驱虫剂) and wear light-colored clothing.

1.How do mosquitoes locate their targets, according to the article?

A.By seeking out bright clothes.

B.By identifying different blood types.

C.By sensing an increase of carbon dioxide.

D.By following bigger crowds.

2.Why are pregnant women more likely to be bitten by mosquitoes?

A.Their larger size helps mosquitoes to see them.

B.They breathe out more CO2.

C.They are more likely to sweat.

D.Their body temperatures are higher.

3.How does the article advise you to avoid mosquitoes?

A.Exercise regularly.

B.Wear light-colored clothing.

C.Keep your skin dry and clean.

D.Stay indoors in the evening.

4.What’s the article mainly about?

A.A new finding about mosquitoes.

B.How people can avoid mosquito bites.

C.A popular myth about mosquitoes.

D.Why some people are more attractive to mosquitoes than others.

While we may think it feels good to complain, complaining has some bad effects associated with it.

Why isn't complaining beneficial? Research shows that it connects our brain with negativity.The brain is designed to work efficiently.This means that when we repeat a thought, negative or positive, the nerve cells form a bridge between each other to pass information in a higher speed.Therefore, the next time we have a similar type of thought, it is more easily passed.This explains why certain thought patterns become habits.

Yet the harmful effects don't stop there.A study shows that complaining causes the hippocampus(海马区), which plays a vital role in problem-solving, to become smaller.

In addition to causing brain damage, complaining also releases a stress hormone: cortisol, a kind of chemical the body produces when we meet with some danger.Constantly having a high level of cortisol results in high blood pressure, high blood sugar, and lower immunity(免疫力).

The ill effects of our complaining aren't just limited to ourselves: they also involve those around us.We tend to mirror the moods of our friends.For this reason, we should be cautious about having stubborn complainers in our circle of companions.

The best way to deal with constant negativity is to develop a sense of gratitude(感恩).Just like complaining acts as a poison, gratitude acts as a medicine.Research shows it lowers cortisol levels by 23 percent, as well as reduces blood pressure and blood sugar.It also decreases tiredness and depression.Gratitude is the perfect cure for complaining, a behavior that steals our brain power, happiness and physical well-being.
