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.

1.According to the passage, the most important type of insects are ________.

A. insects that are eaten by birds, reptiles and fish

B. insects that travel around and pollinate plants

C. insects that harm mosquitoes and stop the spread of disease

D. insects that are eaten by people in many countries

2.According to the passage, insects are eaten in some parts of the world because ________.

A. they are nutritious

B. they are available to cook

C. they are easy to breed

D. they are free

3.According to the author, the sentence in the last paragraph “you should not automatically reach for the bug spray.” means ________.

A. you should not keep insects as pets

B. you should not breed insects for their benefit

C. you should not catch insects for pleasure

D. you should not kill insects without thinking

4.The main purpose of this passage is ________.

A. to explain why it is cruel to kill bugs

B. to convince people that insects are nutritious

D. to make people aware of endangered insect species

科目：高中英語(yǔ) 來(lái)源：2016-2017學(xué)年湖南婁底雙峰一中等五校高一上期中聯(lián)考英語(yǔ)試卷（解析版） 題型：閱讀理解

Through history, children have played with toys and they help to prepare children for adult life. But the toys are changing all the time. As science and technology have changed the way adults live, the toys children play with have changed as well. Development in science and technology has had a big effect on the toys that children play with. Today trains and mobile phones are popular toys for young children, but there were no toys of this kind before real trains and mobile phones were invented. The materials that toys are made of have also changed. Today lots of toys are made of plastic. Plastic is a modern, man-made material that did not exist in the past. On the other hand, some other toys that you have might not be all that different from the ones children played with 1,000 years ago. Scientists have found some bone dice(骰子) in Aberdeen. In medieval(中世紀(jì)的) times dice were used for playing games as much as they are today.

A recent survey found that half of all the children aged from 4 to 6 have played video games, a quarter of them regularly. The increasing use of electronic toys troubles Dr Singer, a professor at Yale. “One thing we know is that kids in early years need to be in touch with the real world,” he said, “no matter how brilliant they are, they’re not going to learn to walk, to move or to talk to others unless their hands or feet have a direct role in such activities.”

Some toy experts argue that the best toys are the ones that increase a child’s creativity and imagination. Traditional toys can be used for different kinds of purposes and be used in group settings, individually(單獨(dú)地), and one-to-one. They are also used differently depending on the child’s age and skill level. And these toys made of natural materials are valuable for children because they teach children what the world is made of.

1.In how many ways do toys change according to the first paragraph?

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

2.The author used the example of “dice” to show that ________.

A. the toys are changing all the time

B. some toys are made of different materials

C. some toys don’t change over time

D. some toys’ materials don’t change over time

3.From the article, we can know that ________.

A. only children like to play with toys

B. toys have nothing to do with children’s future life

C. the development of toys is related to science and technology

D. plastic is the best material for making toys

4.According to Dr Singer, ________.

A. the electronic toys are good for children if they play often enough

B. the electronic toys prevent children keeping in touch with the real world

C. children should be stopped from being hurt by the danger coming from the outside world

D. children should play with electronic toys instead of the traditional ones

Sri Lanka is known as the “Pearl of the Indian Ocean”, and it is easy to see why. This little country never fails to please visitors.

Arrive

The national airline is Sri Lankan Airlines, which flies from Colombo to London and a couple of other European cities. The country’s main airport is Colombo Bandaranaike, located 29km north of the capital city.

Why now?

The best time to visit Sri Lanka’s southern beaches is from November to April. So by going early in the season, you’ll get the best weather. Also in November, Deepavali, known as “Diwali” or the “Festival of Lights”, is Sri Lanka’s main religious festival, celebrated throughout the country.

See

There is plenty to see in Sri Lanka. The ancient capital cities of Polonnaruwa and Anuradhapura are worth seeing, and so are many outstanding ruins. Other must-sees are the rock fortress (要塞) of Sigiriya, towering over the jungle as far as the eye can see, and Dambulla’s cave temple, the country’s largest and best preserved. Both are UNESCO World Heritage (遺產(chǎn)) Sites. Kandy is a picture-like town, which was the last stronghold of the Kandyan Kings. Today it is a cultural relic centre where age-old customs, arts, and crafts remain.

Do

Sri Lanka owns about 1,600km of beautiful palm-shaded beaches as well as warm, pure seas and colourful coral reefs. You can explore the underwater world, and surfing and diving are available too. Away from the shore, wildlife is a big draw for Sri Lanka, and Yala National Park is one of the best places in the world to see wild animals including leopards (豹) and elephants.

Taste

Sri Lanka is celebrated for its excellent food, with a particular emphasis on fresh fruit and vegetables on menus everywhere. Fish and seafood are a big part of the local diet.

A. Kandy.B. Anuradhapura.C. Polonnaruwa.D. Colombo.

2.If you want to know something about “Diwali”, you’d better go there in ________.
