Butterflies are some of the most fascinating and beautiful insects in the world. Adult butterflies will live about 2 to 4 weeks. They use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry enemies.

Butterflies have large compound eyes(复眼), which allow them to see in all directions without turning their heads. Like most insects, butterflies are very near­sighted, so they are more attracted to a sea of flowers than individual plants. Butterflies do not “see” colors such as red, green, and yellow, but they can sense sunlight, which indicates the direction the sun is shining, as well as ultraviolet light（紫外线）, which is present on many flowers and guides butterflies to honey sources.

Butterflies have a very well-developed sense of smell, but it is not in their nose, since they don't have one. Sense receptors are located in their antennae（触角）, feet, and many other parts of the body. They can help butterflies find their favorite flower honey food, and mates.

Butterflies' feet have sense organs that can taste the sugar in flower honey, letting the butterflies know if something is good to eat or not. Some females also carefully choose host plants by tasting to find appropriate places to lay their eggs. Adult butterflies feed their babies using a long tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.

Butterflies don't have ears. Instead they “hear” sounds through their wings by sensing changes in sound vibrations（振动）.

Butterflies may possess senses we don't even know about yet, because their body structure is very different from ours, and therefore difficult to understand, when observed through our own human senses.

1.What can we learn from the 2nd paragraph?

A. Butterflies have good eyesight.

B. Butterflies can see in all directions and don't need to turn heads.

C. Butterflies are sensitive to bright colors including red and yellow.

D. Butterflies cannot sense the ultraviolet light.

2.How do butterflies hear sounds?

A. Using their feet to sense the vibration of things

B. Using their ears to listen directly

C. Using their wings to sense the sound vibrations

D. Using their antennae to judge the sound

3.Why do female adult butterflies carefully choose the host plants?

A. To find high­qualified honey.

B. To have a good place for living.

C. To make it easier for them to hide from the enemies.

D. To find a proper place for their eggs.

4.What does the last paragraph imply?

A. There’s a long way to understand butterflies well

B. Butterflies give great help to human beings

C. Butterflies are the most beautiful insects in the world

D. Butterflies possess more senses than humans

5.The text mainly focuses on ________.

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

C.to describe the beneficial contributions of insects

D.to make people aware of endangered insect species

高三英语单项填空简单题查看答案及解析

Some of the United States’ biggest banks have closed their doors to students at community colleges, for-profit universities and other less competitive schools, even as they continue to extend government-backed loans to students at eh nation’s top universities.

Citibank has been among the most active in rebuilding the list of colleges it serves. JPMorgan Chase, PNC and SunTrust say have not dropped whole loan plans, but are cutting colleges. Some less-selective four-year colleges, like Eastern Oregon University and William Jessup University, say they have been dropped by some lenders.

The practice suggests  that if the credit crisis and poor conditions in the student loan business continue, some of the nation’s neediest students will be hurt most. The difficulty of borrowing money may keep them from attending school or force them to take a semester（学期） off.  For those who have got student loans, they will end up with less attractive terms and may run a greater risk of dropping out if they have to change lenders in the middle of their college year.

Tuition and loan amounts can be quite small at community colleges. But these institutions, which are a stepping stone to other educational programs or to better jobs, often draw students from the lower ranks of the economic classes. According to the most recent data, about a third of US graduates took out loans, a majority of them guaranteed by the government.

“If put too many obstacles in their way to get a loan, they ’ll take a third job or use a credit card,” said Jacqueline K. Bradley, assistant director for financial aid at Mendocino College. “That almost guarantees that they won’t be as successful in their college career.”

Some loan companies have stopped the students loan business entirely, viewing it as unprofitable in the current environment. Students attending first-class, expensive, public and private four-year universities can expect to remain plentiful. The banks generally say these loans are bigger, more profitable, and less risky, perhaps in part because the banks expect graduates from these universities to earn more.

So far, financial aid administrators say they have been able to find some lenders that students can switch to, but this is costly to students--- in money and time.

59. Who will be the most upset at the news?

A. A poor students at a top university.          B. A poor students at a community university.

C. A bank clerk dealing with student loan business.

D. A teacher from a for-profitable university.

60. With too many obstacles in their way to get a loan, students will probably __________.

A. switch to top universities                       B. cancel their credit cards

C. fail in their exams                                 D. win a scholarship

61. When they say something is “government-backed”, you mean it is ___________.

A. guaranteed by the government                B. dropped by the government

C. against government                               D. for government

62. What is the best title for the passage?

A. The students loan business in America.    B. Banks and universities in America.

C. Student loans start to drop colleges.        D. Credit crisis starts to affect loans.
