The brown widow spider became established in Southern California in early 2000 and has become part of the local spider family in urban Los Angeles and San Diego. The brown widow spider is continuing its expansion in Southern California and could possibly move northward into Central California.
The brown widow is suspected to have evolved in Africa although it was first described from South America, which adds confusion as to where it might have originated. It is a tropical and subtropical spider having established populations in Hawaii, Florida, parts of Australia, South Africa and Japan. In North America, the brown widow was restricted for many decades to the Florida peninsula. However, around the year 2000, it started showing up in other Gulf Coast states. Brown widows are now known from Texas to Georgia and South Carolina.
The brown widow builds its web in protected sites around homes and in woody vegetation with branches. Some typical sites selected by brown widows for web building are empty containers such as buckets and nursery pots, mail boxes, entry way corners, under eaves, storage closets and garages, undercarriages of motor vehicles that are stationary for long periods, and the undersides of outdoor furniture. They choose places that are more exposed than sites chosen by black widows and therefore, appear to be at higher risk for interactions with humans as far as bites are concerned.
One recent study demonstrates that the brown widow spider is less poisonous than other widow species. The reason for the weaker effect of brown widow bites on humans is possibly because the brown widow does not have much poison as its larger relatives, but it is really a threat to humans as to its poison. The two major symptoms of a brown widow bite were that the bite hurt when it was given and it left a red mark. These two symptoms are not much different from the bite of normal household spiders.
There is no specific information regarding the control of brown widows by farm chemicals. Most current advice is what is used for controlling spiders in general. Therefore, most commercially available farm chemicals should work on brown widows. Avoiding a mess of the house and the garage should reduce nest sites for them. Also, one should store garage items in plastic bags where there might be interactions with spiders. These items include rarely worn garments such as gardening clothes and gloves, recreational items like sports equipment (i.e., baseball gloves) and other items where spiders can crawl up into holes where fingers can be inserted.
67. The author wrote this article to _______.
A. announce the result of a research on spiders
B. introduce the ways to get rid of the spiders
C. report a new finding of the widow species

68. From the passage we can conclude that _______.
A. brown widows are spreading northward
B. the brown widow originated from Africa
C. brown widows now can be found in all countries
D. there used to be no brown widows in North America
69. The third paragraph is mainly about _______.
A. the brown widow’s web building
B. the characteristics of the brown widow
C. the habitat preferences of the brown widow
D. the brown widow’s threaten to human beings
70. It can be inferred that _______.
A. brown widows can be killed with any farm chemicals
B. at present people can only control brown widow spiders
C. the brown widow has more poison than the black widow
D. victims bitten by the brown widow needn’t see the doctor

B
He was an old man who fished alone in a boat in the Gulf Stream and he had gone eighty-four days now without taking a fish. In the first forty days a boy had been with him. But after forty days without a fish the boys parents had told him that the old man was now definitely salao and he finally would be so. The boy had gone at their orders in another boat which caught three good fish the first week. It made the boy sad to see the old man come in each day with his skiff empty and he always went down to help him carry either the coiled lines or the gaff(鱼钩) and harpoon(鱼叉) and the sail that as rolled around the mast(桅杆). The sail was patched with flour bags and, rolled, it looked like the flag of permanent defeat.
The old man was very thin with deep wrinkles in the back of his neck. The brown blotches(斑点) of the skin cancer the sun brings from its reflection on the tropic sea were on his cheeks. The blotches ran well down the sides of his face and his hands had the deep-creased scars from handing heavy fish on the cords. But none of these scars were fresh. They were as old as erosions in a fishless desert. Everything about him was old expect his eyes and they were the same color as the sea and were cheerful and undefeated.
“Santiago,” the boy said to him as they climbed the bank from where the boat was pulled up. “I could go with you again. We’ve made some money.” The old man had taught the boy to fish and the boy loved him.
“No,” the old man said. “But we have. Haven’t we?
“Yes,” the boy said. “Can I offer you a beer on the Terrance and then we’ll take the stuff home.”
“Why not?” said the old man, “between fisherman.”

A. lonely B. unlucky C. selfish D. stubborn
56. The boy left the old man and went in another boat to fish because _______.
A. the old man preferred to fish alone B. the old man was poor
C. the boy’s parents ordered him to D. the old man’s sail suggested a permanent defeat

A. the old man was insistent and not afraid of failure
B. the boy’s papa had confidence in everything
C. the old man caught big fishes because he had some doubts about the old man
D. the boy obeyed his father because he had some doubts about the old man

Green Christmas
A.A real tree B.Eco-friendly Christmas C.Green advice D.Recycle or replant |
Are you dreaming about a white or green Christmas?
Traditionally, most people hope for a white Christmas in the UK. However, more and more individuals are working towards making it a green one.
With environmental issues a high priority on the social and political agenda, Brits are keen to enjoy the festivities and, at the same time, be kind to the planet.
1
Statistics show that more waste is produced at Christmas by the food and drink we consume and the presents we exchange. With this in mind, the government and the public are making a conscious effort to make 2006 an eco-friendly Christmas.
2
For example, the Scottish Executive has dedicated a section of its website to advising the public on the different ways they can have a green Christmas.
Suggestions include re-using old Christmas cards and wrapping paper, using energy-saving Christmas lights, and saving product waste by buying “experience” gifts, like theatre tickets or a museum pass.
3
Another suggestion on the site was made by Duncan McLaren, from Friends of the Earth Scotland. He said: “If you really must have a Christmas tree, then make it a live one.” This idea is also recommended by local councils across England.
Suffolk Coastal District Council, for example, has encouraged local residents to buy a real Christmas tree which can be planted out or composted after the festive season.
4
Councillor Andrew Nunn, the Cabinet Member for the Environment, said: “Trees with roots can be replanted in the garden either for re-use next year or just left to grow to enhance the garden scene. People are often put off buying a real tree because of falling needles, but this is now a thing of the past with new varieties of trees being grown that hardly shed any. Needles that do fall can be swept up and put on the compost heap or in the brown garden waste bin for recycling.”
