To many web-building spiders, most of whom are nearly blind, the web is their essential window on the world: their means of communicating, capturing prey, meeting mates and protecting themselves. A web-building spider without its web is like a men cast away on an island of solid rock，totally out of touch and destined to starve to death. So important is the web to an orb-web spider's survival that the animal will continue to construct new webs daily even if it is being starved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets scrawnier, it constructs a wider-meshed （网孔、网眼）web using fewer strands（线）. Such webs would only trap larger prey, which is more economical from the perspective of a starving spider. The spider stores energy by recycling web protein. It simply eats its own web each evening and reuses it to produce new silk. In studies with radioactivity, labeled materials, it was found that 95 percent of web protein reappears in the next day web. Most of the energy needed for web-building is used in walking over the strands as they are laid down. Scientists are impressed by the adaptability of the spider's highly preprogrammed brain, which is larger for its size than the brain of any other invertebrate（无脊推动物）. If web-building is interrupted, or if some of the existing strands are destroyed, the spider simply goes back to see where the web is left off and then finishes building a normal web. One spider will finish building the incomplete web of another.

1.Which of the following best expresses the main ideas of the passage?

A. Secrets of Spiders' Adaptability

B. Importance of Webs to Spiders

C. Secrets of the Spiders' Life

D. Spiders' Highly Preprogrammed Brain

2.According to the passage, which of the following statements is TRUE?

A. Most spiders will stop conducting webs when hungry.

B. One Web-building spider usually conducts one web.

C. Web-building spiders will probably die without their webs.

D. Web-building spiders have good eyesight.

3.The underlined word “scrawnier” in the second paragraph probably means ______.

A. weaker but good-looking

B. fatter and stronger

C. nice and healthier

D. thinner and bony

4.A spider's ability to finish an incomplete web proves that ______.

A. it has a highly preprogrammed brain

B. it reuses its web protein to reproduce new silk

C. the web is everything for a spider

D. it is able to rebuild a destroyed web

Bees play a vital role in the world. Unfortunately, bees are dying by the second.

The main purpose of bees is to make honey. Honey, shockingly, does not exist for human consumption, it is essential to the insects. Honeybees store honey in their hives (蜂巢) in order for the bees to have energy for their flight muscles and for heating the hive during the winter period. They collect pollen (花粉) which supplies protein for young bees to grow.

According to Honey, com, the increased production and quality of agricultural crops as a result of honey bee pollination is valued &t more than1 $14/ 6 billion per year. These insects are responsible for over 70 of the fruits and vegetables we eat today, including apples, grapes, coffee, beans, and broccoli.

So if they are so valuable to agriculture, why do they keep dying off? A key suspect seems to be pesticides (农药). Honeybees who are exposed to pesticides result in the damage to their neurological (神经的) functions, specifically memory or behavior. And that's why the majority of worker bees disappear and leave behind a queen, plenty of food and a few nurse bees to care for the remaining immature bees and the queen. There are several other causes to the decline of bees, including the destruction of natural habitat, like woodlands, forests, and other habitats for bees. Climate change is also a factor in the decline of the wild bee population.

Actually, there are a variety of methods to help the bee population grow. One way is to start your own organic garden by planting bee-friendly plants. Pesticides are used in both industrial practices and even in your home, so it is best to find organic seeds and weed killers.

1.Why do honeybees store honey in their hives?

A. To provide enough honey for human to consume.

B. To draw protein out of honey for young bees.

C. To help attract other insects and make hives stronger.

D. To strengthen bee muscles and heat hives in winter.

2.Apples and beans are mentioned in the third paragraph to show that _.

A. bees supply human beings with basic food

B. bees mainly live on these agricultural crops

C. bees are of great importance to fruits and vegetables

D. bees can bring in more money for famers every year

3.What is most likely to cause the worker bees to leave their hives behind?

A. The lack of food.

B. The abuse of pesticides.

C. The fighting among bees.

D. The destruction of the habitats.

4.What would the author probably discuss in the paragraph that follows?

A. Another way to save bees.

B. Other tips for choosing seeds.

C. More methods to plant green organic fruits.

D. Causes of the decline in the wild bee population.

Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)-either recorded or real-may even prevent elephants from damaging farmer's crops.

In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today,　 Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.

Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family.

From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.

Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.
