How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?

In the southwest African country of Namibia, and the Sahara lands of Mali further north, the desert elephant does just that.

Although not regarded as a separate species from the African elephant, the desert cousin differs in many ways. Their bodies are smaller, to absorb less heat, and their feet are larger for easier walking across sandy surfaces. They are taller, to reach higher branches. They have shorter tusks（象牙）， and most importantly, longer trunks to dig for water in riverbeds.

Desert elephants can travel over 70 kilometers in search for feeding grounds and waterholes, and have a larger group of families, They drink only every 3-4 days, and can store water in a “bag” at the back of their throat, which is only used when badly needed. Desert elephants are careful feeders ----- they seldom root up trees and break fewer branches, and thus maintain what little food sources are available. Yong elephants may even eat the dung（糞便）of the female leader of a group when facing food shortage.

During drought they are unlikely to give birth to their young but with good rains the birthrate will increase greatly. Desert elephants have sand baths, sometimes adding their own urine(尿液) to make them muddy!

As we continue to overheat our weak planet, it can only be hoped that other animal species will adapt as extraordinarily well to change as the desert elephant.

46．Desert elephants are called careful feeders because they   

A．rarely ruin trees              B．drink only every 3-4 days

C．search for food in large groups  D．protect food sources for their young

47．The author answers the question raised in the first paragraph with   

A．stories and explanation        B．facts and descriptions

C．examples and conclusion       D．evidence and argument

48．What can be inferred from the last sentence in the passage?

A．Overheating the earth can be stopped．

B．Not all animal species are so adaptable.

C．The planet will become hotter and hotter.

D．Not all animals are as smart as desert elephants.

科目：高中英語(yǔ) 來(lái)源：河南省許昌高中2011屆高三上學(xué)期第一次摸底考試試卷（英語(yǔ)） 題型：閱讀理解


第三部分：閱讀理解（共20小題，每題2分，滿分40分）
閱讀下列短文，從每題所給的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)，并在答題卡上將該項(xiàng)涂黑。
French people pride themselves on their delicious foods, such as cheese, baguettes and croissants (two kinds of food). In fact, food is an important part of French culture. Families and friends spend hours over the dinner table each night. It is the opposite of the fast – food habit common in other parts of the West.
It’s the reason why the French are very angry that a McDonald’s is opening beneath Paris’s most famous museum: the Louvre (盧浮宮). The mew restaurant will be the 1,142 nd McDonald’s in France, and will open in the underground approach to the museum. But many French people can’t understand why this American chain is opening in the heart of French culture.
However, McDonald’s is paying no notice to the complaint. McDonald’s now has 31,000 chains worldwide. Tourists are hungry, and opening chains in tourist spots pays well.
There is another chain threatening France’s heritage. This time it is coffee rather than burgers. As more and more Starbucks open in Paris, traditional French cafes are forced to close.
The trouble with American companies opening chains throughout the world is the destructive effect they can have on a country’s culture. How can a small, independent coffee shop compete with the multi – billion dollar chain? You can go to a Starbucks in any city in the world, but you can only go to a Parisian café in France.
Responsibility is with the tourists. A McDonald’s wouldn’t open so near the Louvre if it weren’t not going to make money. Similarly, a Pizza Hut wouldn’t overlook (俯瞰) Egypt’s Great Pyramid if no one wants to sit in it. Maybe next time you visit the Great Wall, you should think twice before ordering a Cappuccino in the Starbucks.
51．Why are the French very angry when a McDonald’s is opening beneath the Louvre?
A．Because they will spend many hours in McDonald’s.
B．Because French food culture is very impressive.
C．Because they also have the fast – food habit.
D．Because they are proud of their own food.
52．The McDonald’s will be located in the underground approach to the museum because_______.
A．the complaints of the French are useless
B．opening a chain in tourist spot is rewarding
C．McDonald’s tends to be in the heart of culture
D．it will help to attract more tourists for the museum
53．What is the trouble with American companies opening chains all over the world?
A．The traditional stores of a country are forced to fight back.
B．The traditional stores of a country become dependant.
C．They have negative effect on a country’s culture.
D．The multi – billion dollar chain can’t be matched.
54．The author suggests that the tourists can_______.
A．decide whether the multiple stores of America are successful or not
B．order a Cappuccino in the Starbucks when they visit the Great Wall
C．sit in a Pizza Hut when they visit Egypt’s Great Pyramid
D．enter the McDonald’s when they visit the Louvre
