【推荐1】Soda is refreshing and delicious, but it is not part of a healthy, balanced diet. Most sodas are packed with sugar. In fact, a can of soda can be hiding up to 10 teaspoons of sugar! The sugar does make soft drinks delicious, but definitely not nutritious. Too much sugar in a person’s diet can lead to diabetes (糖尿病), heart disease, and tooth problems. One of the biggest sugary soda problems is that drinking much can lead to weight gain and even obesity.

There are diet options available for almost every kind of pop (汽水), which means that you don’t have to drink all that sugar in order to enjoy a can of soda. Many studies have been done on whether or not aspartame (甜味剂), the sugar substitute in diet soda, is bad for you. Up to now, there are still conflicting opinions on this issue. The European Food Safety Authority recently concluded that aspartame is safe for most people, even in fairly large amounts. Aspartame still might not be good for you, though. Studies have shown that people who drink diet sodas may actually gain more weight than those who drink regular soda, perhaps because, strangely enough, drinks loaded with fake sugar may actually make you want to eat more.

Maybe you’ve decided it’s time to cut down on your soda drinking, but what should you drink instead? Water is absolutely the healthiest thing that you can drink. Your body needs water to stay hydrated (含水的) and function properly, and water contains no calories or fat. Drinking fruit juice occasionally is not a bad thing, but you should be careful what juice and how much juice you’re drinking. Fruit juices can contain almost as much sugar as pop!

As with most things to do with your health, moderation is really at the base of any healthy diet. You can totally drink soda, even the sugary kind just, make sure you’re not drinking too much!

【推荐2】On holidays you' re likely to eat and overeat between family gatherings, office parties and celebrations with friends.     1    . Here are some tips to help you enjoy holiday food without completely changing your diet:

①. Switch to small plates.

Not only do smaller dishes fill up faster, but the same amount of food looks like more when it's on a small dish.     2    . But whatever the size of your plate, it's most important to remember to keep it balanced: half for vegetables, a quarter for grains and a quarter for meat.

②. Measure out snacks.

Your favorite holiday movie is on. Take a minute to check the nutrition label (标签) and measure out a serving (一人份) to keep calories under control. Take one popular brand of buttered microwave popcorn for example.     3    . But the bag contains 2.5 servings. Eat the whole thing on your own, and you'll have eaten 425 calories.

③. Divide a main dish.

Many restaurants serve far more food than one person needs in a single meal.     4    . Or pack half your main dish to go as soon as it's served. Or choose a small-size option, if available.

④. Stop eating when you feel satisfied.

You don't have to feel too full, or force yourself to clean your plate, before putting down your fork. You're aiming for feeling no longer hungry instead of a complete fullness that indicates you've overdone it.    5    . When you're satisfied, save the rest for tomorrow.

A．Share a main dish with a friend

B．It's important for you to eat more on holidays

C．Eat slowly and pay attention to feelings of hunger

D．Studies show we tend to put on a few pounds this time of year

E．Enjoy a main dish slowly by yourself

F．So you'll be likely to serve yourself less

G．One serving is about 4 cups with 170 calories

【推荐3】Breakfast is the most important meal of the day. It is also the most neglect (忽视). Common reasons for not eating breakfast include having no time, not feeling hungry, traditional dislike and dieting.

Breakfast simply means “break the fast’’. Your body spends at least 6 to 12 hours each night in a fasting state. In the morning your body needs energy for the day’s work ahead.

A good breakfast should provide 1/3 of your total calorie(卡路里)needs for the day. On average, we eat 400 less calories for breakfast than for dinner. If breakfast doesn’t appeal (吸引) to you in the morning, try eating a lighter dinner earlier in the evening or save half of your dinner for breakfast in the morning.

If you still aren’t hungry in the morning, start with something small like juice or toast or have a nutritious (有营养的) mid-morning snack (小吃) later when you are hungry.

So, you say you are on a diet. Some people fear that eating breakfast will make them hungrier during the day and they will eat more. It is true that eating breakfast is likely to make you feel hungry throughout the day. That is because your body is working correctly. Although you may feel as if you are eating more all day long, in reality you are probably not.

Not eating breakfast can also cause you overeat, since a fall in blood sugar often makes you feel very hungry later. To make matters worse, since your body is in a slow state, it will not be able to burn those extra calories very efficiently (有效). If you feed your body healthy snacks and meals throughout the day, you are less likely to become hungry and stuff (填饱) yourself as soon as you begin to eat.

Since breakfast is the first and most important meal of the day, choosing the right food is important. The best breakfast foods are fruits, juice, lean meat and grain products such as bread, rice, noodles and cereals.

【推荐1】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.

【推荐1】Write NO MORE THAN THREE WORDS for each answer.
A consumercomplaint or customer complaint isan expression of dissatisfaction on a consumer’s behalf to a responsible party. It can also be described in a positive sense as a report from a consumer providing documentation about problems with a product or service.
So what are the common reasons for customer complaints? The most common complaints about retail(零售) storesfall into several aspects. First, they have to circle the filled parking lot endlessly, which is a waste of time and a test for their patience. They also can’t stand clutteredshelves, over-loaded racks, out-of-stock items and long check-out lines. Worst of all, sometimes some salespeople are rude, turning their mood into a bad one.
In fact, some modern business consultants urge businesses to view customer complaints as a gift but not a trouble.Some retailers, however,ignore complaints or deal with them dishonestly, which can cause a chain of events like bad reputation, leave theirbusiness with fewer and fewer customers. The resulting “snowball effect” can be disastrous to retailers.In the most severe cases, it can even cause companies to shut down.
Increasing competition is forcing companies to take more effective measures to satisfycustomers and better their customer service.During peak shopping hours, some moonlighting(业余兼职的) local police have been employed as parking attendants bysome retailers to solve the parking problems. Some hire flag wavers to direct customers to parking spaces that are empty. This guidance can avoid confrontation between those eyeing the same parking space.Retailers can relieve the headache by redesigning store layouts, pre-stocking sales items, hiring the cashiers with much experience, and having sales representatives on hand to answer questions.Most importantly, salespeople should be trained to deal with angry customerswith politeness.Try their best to resolve the problem if they can.
Quickly and properly solving customer complaints can help retailers smooth over issues and their business can grow and prosper.

【推荐3】For humans, adapting to climate change will mostly be a matter of technology. More air conditioning, better-designed houses and bigger flood defenses may help lessen the effects of a warmer world. Animals will have to rely on changing their bodies or their behaviour. In a paper published inTrends in Ecology & Evolution, a team led by Sara Ryding, a professor in Australia, shows that is already happening. In some species of Australian parrot, for instance, beak size has increased by between 4% and 10% since 1871. Similar trends are seen in species of mice and bats growing bigger ears, tails, legs and wings.

All that fits nicely with evolutionary theory. “Allen’s rule”, named after Joe Allen, who suggested it in 1877, holds that warm-blooded animals in hot places tend to have larger appendages than those in mild areas. Such adaptations boost an animal’s surface area relative to its body volume, helping it to shed extra heat. Fennec foxes, meanwhile, which are native to the Sahara desert, have strikingly large ears, especially compared with their Arctic cousins.

Ryding’s team combined data from different species in different places. Now that they have little in common apart from living on a warming planet, climate change is the most reasonable explanation. Since any evolutionary adaptation comes with trade-offs, it is unclear how far the process might go. Bigger beaks might interfere with feeding, for instance. Larger wings are heavier, and bigger legs cost more energy to grow.

Honestly, studying a broader range of animals will help firm up exactly what is happening. For now, at least, the increase is small, never much more than 10%. That may change as warming accelerates. But it seems clear that the world of the future is not just going to be hotter than humans are used to. The animals living in it will look different, too.
