If you look outside, you probably will see some kind of insect. If your first instinct is to kill it, take a moment to think about all of the benefits insects provide to the environment.
Entomologists, scientists who study insects, estimate that there are more than 800,000 species of insects found throughout the world. Only a few hundred of these insects are considered harmful. Mosquitoes, for example, are considered harmful. They bite humans and other animals, and their bites can cause skin pain and spread disease. Desert locusts also are considered harmful because they destroy crops causing billions of dollars in damage each year.
However, the number of helpful insect species far outweighs the number of harmful species. Some insects make up a vital part of the food chain. Many different birds, reptiles, fish and even plants eat insects. There are also about 500 insects that people in various parts of the world eat. These insects are considered delicious food and prized for their high protein, mineral, and vitamin content. Other insects produce valuable commercial products such as silk, wax, and honey.
Of all the insects, perhaps the most important are those that travel from flower to flower and pollinate(授粉) the plants they visit. Agriculture around the world would be very different without the bees, butterflies, moths, flies and wasps that pollinate many crops. In fact, nearly one-third of the food you eat depends on plants that are pollinated by insects!
While it is true that some species of insects harm or annoy us,you should not automatically reach for the bug spray when you come across an insect. You may be destroying one of the hundreds of thousands of insects that provides many benefits to human beings.

Healthy See, Healthy Do
Visit the grocery store on an empty stomach, and you will probably come home with a few things you did not plan to buy. But hunger is not the only cause of additional purchases. The location of store displays (摆放) also influences our shopping choices.1.
The checkout area is a particular hotspot for junk food. Studies have found that the products most commonly found there are sugary and salty snacks.2. A 2012 study in the Netherlands found that hospital workers were more likely to give up junk food for healthy snacks when the latter were more readily available on canteen shelves, for example. In 2014 Norwegian and Icelandic researchers also found that replacing unhealthy foods with healthy ones in the checkout area significantly increased last-minute sales of healthier foods.
3. It has been working with more than 1,000 store owners to encourage them to order and promote nutritious foods. “We know that the stores are full of cues (暗示) meant to encourage consumption,” says Tamar Adjoian, a research scientist at the department, “Making healthy foods more convenient or appealing can lead to increased sales of those products.”
Adjoian and her colleagues wondered if such findings would apply to their city’s crowded urban checkout areas, so they selected three Bronx supermarkets for their own study. 4. Then they recorded purchases over six three-hour periods in each store for two weeks.
Of the more than 2,100 shoppers they observed, just 4 percent bought anything from the checkout area. Among those who did, however, customers in the healthy lines purchased nutritious foods more than twice as often as those in the standard lines.5. The findings were reported in September in the Journal of Nutrition Education and Behavior.
The potential influence may seem small, but Adjoian believes that changing more checkout lines would open customers’ eyes to nutritious, lower-calorie foods. Health department officials are now exploring ways to expand healthy options at checkout counters throughout New York City.
A. These foods give people more energy.
B. They bought unhealthy foods 40 percent less often.
C. And it may make or break some healthy eating habits.
D. The supermarkets began to offer nutritious, lower-calorie foods.
E. These findings caught the attention of New York City Department of Health.
F. They replaced candies and cookies with fruits and nuts near the checkout counter.
G. And a few studies have suggested that simply swapping in healthier options can change customer behavior.

If you’re like most students, you probably read both at home and outside your home: Perhaps somewhere on your schoolyard and maybe even at work during your breaks. Your reading environment can have a great effect on your understanding, so give some thought to how you can create（营造）or choose the right reading environments. The right environment allows you to stay alert （专注的）and to keep all of your attention on the text, especially when it is both interesting and difficult.
When you’re at home, you can usually create effective conditions for reading. You might want to choose a particular place-----a desk or table, for example ----where you always read. Make sure the place you choose is well lighted, and sit in a chair that requires you to sit straight. Reading
In a chair that’s too soft and comfortable is likely to make you sleepy! Keep your active reading tools (pens, markers, notebooks or paper) and a dictionary close at hand.
Before you sit down for a reading period, try to reduce all possible interruptions. Turn off your phone, the televisions, and the radio. Tell your family members or roommates that you’ll be busy for a while. If necessary , put a “Do not disturb” sign on your door! The more interruptions you must deal with while you read, the harder it will be to keep your attention on the task at hand.
1.The author believes that the right reading environment _______.
A. helps readers a little in their reading tasks
B. helps readers a lot in their reading tasks
C. can only be created at one’s home
D. can only be created outside one’s home
2.Which type of the following interruptions is mentioned in the text?
A. Dictionaries B. Paper C. Notebooks D. Phone calls
3.What would be the best title for the text?

C. Creating an Effective Reading Environment D. How to Read Fast
