When people get a bad toothache, they often have to eat soft, easily chewed food.  _____ That’s the conclusion of a zoologist at the Field Museum of Natural History in Chicago and a dentist who works on carnivores (食肉動(dòng)物).

_____ Every once in a while, however, a lion will go on a human-eating diet.  The most famous such tragedy happened in 1898, when two lions killed and ate 135 railway workers in Kenya. 

Examining the preserved skulls of the two big lions, zoologist Bruce Patterson and dentist Ellis Neiburger found that both animals had been suffering from several dental and jaw problems. ______ Canines are pointed teeth that hunting animals use for gripping and piercing prey . 

       The two lions might have been so badly disabled that they couldn’t bite down forcefully, say the researchers. Consequently, the lions might have abandoned their normal, more difficult prey and turned to humans.  Patterson said “_________ We’re very slow, we don’t hear very well, and we don’t see very well in the darkness.”

       __________ It was inspired partly by the work of Jim Corbett, a tiger hunter in India in the 1930s.  Corbett was regularly called in to hunt tigers that had been dining on Indian villagers. Time after time, Patterson discovered that the killer tigers were suffering from some ill-healthy conditions.

 (10·山東B篇)

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.

The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.

Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue , encouraging customers to reuse their plastic bags, for example.

But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But is also applies to a wide range of consumer products, which often have far more packaging than necessary.

There are signs of hope. As more of us recycle, we are beginning to realise just how much unnecessary material are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.

61. What does the underlined phrase “over-consumption” refer to?

A. Using too much packaging.

B. Recycling too many wastes.

C. Making more products than necessary.

D. Having more material than is needed.

62. The author uses figures in Paragraph 2 to show _______.

A. the tendency of cutting household waste

B. the increase of packaging recycling

C. the rapid growth of super markets

D. the fact of packaging overuse

63. According to the text, recycling ______.

   A. helps control the greenhouse effect

   B. means burning packaging for energy

   C. is the solution to gas shortage

   D. leads to a waste of land

64. What can be inferred from Paragraph 4?

   A. Unpackaged products are of bad quality.

   B. Supermarkets care more about packaging.

   C. It is improper to judge quality by packaging.

   D. Other products are better packaged than food.

65. What can we learn from the last paragraph?

   A. Fighting wastefulness is difficult.

   B. Needless material is mostly recycled.

   C. People like collecting recyclable waste.

   D. The author is proud of their consumer culture.

回答問(wèn)題
In choosing a friend, one should be very careful. A good friend can help you study. But how do I know when I have found a good friend? I think a good friend should have certain good qualities(品質(zhì)), especially understanding, honesty and reliability(可靠).
Above all , I look for understanding in a friend. A good friend tries to understand how another person is feeling. He puts himself in the other person’s place, and he tries to think of ways to be helpful. He is also a good listener.
At the same time, however, a good friend is honest. He does not look for faults in others. He notices their good points. In short, a friend will try to understand me and accept me.
Sometimes you will meet “fair weather friends”. They will be with you as long as you have money or luck, but when you are down, they will run away. So, I think another quality of a friend is reliability. I can always depend on a good friend. If he is in trouble, I will do my best to help him. If I need a favor, he will not run away from me.
When I meet someone who is reliable, honest, and understanding, I know I’ve found a friend!
58. According to the writer, what good qualities should a good friend have? (回答詞數(shù)不超過(guò)5個(gè))

科目：高中英語(yǔ) 來(lái)源：2013屆四川省瀘州市高級(jí)教育培訓(xùn)學(xué)校高三上學(xué)期10月月考英語(yǔ)試卷（帶解析） 題型：閱讀理解

Professor Barry Wellman of the University of Toronto in Canada has invented a term to describe the way many North Americans interact(互動(dòng))these days. The term is “networked individualism”. This concept is not easy to understand because the words seem to have opposite meanings. How can we be individuals(個(gè)體)and be networked at the same time? You need other people for networks.
Here is what Professor Wellman means. Before the invention of the Internet and e-mail, our social networks included live interactions with relatives, neighbors, and friends. Some of the interaction was by phone, but it was still voice to voice, person to person, in real time.
A recent research study by the Pew Internet and American Life Project showed that for a lot of people, electronic interaction through the computer has replaced this person-to-person interaction. However, a lot of people interviewed for the Pew study say that’s a good thing. Why?
In the past, many people were worried that the internet isolated(孤立)us and caused us to spend too much time in the imaginary world of the computer. But the Pew study discovered that the opposite is true. The Internet connects us with more real people than expected—helpful people who can give advice on careers, medical problems, raising children, and choosing a school or college. About 60 million Americans told Pew that the Internet plays an important role in helping them make major life decisions.
Thanks to the computer, we are able to be alone an together with other people—at the same time!
【小題1】The underlined phrase “networked individualism” probably means that by using computers people       .

A．stick to their own ways no matter what other people say
B．have the rights and freedom to do things of their own interest
C．do things in their own ways and express opinions different from other people
D．a(chǎn)re able to keep to themselves but at the same time reach out to other people
【小題2】According to the Pew study, what do many people rely on to make major life decisions?
A．Networks.B．Friends.C．Phones.D．Parents.
【小題3】It can be inferred from the Pew study that         .
A．people have been separated from each other by using computers
B．the Internet makes people waste a lot of time and feel very lonely
C．the Internet has become a new tool for a new kind of social communication
D．a(chǎn) lot of people regard the person-to-person communication as a good thing
【小題4】Which would be the best title for this passage?
A．We’re Alone on the Internet
B．We’re Communicating on the Internet
C．We’re Alone Together on the Internet
D．We’re in the Imaginary World of the Internet.
