 Exercise 10. Read the following passage and mark A, B, C, or D to indicate the correct answer to each of the blanks from 46 to 50 .
What make a good souvenir?
            On my desk at home, I have a collection of souvenirs; objects that remind me of places I’ve visited and important events in my life. These objects include a model boat that I saw being carved from a piece of wood on a Caribbean island, a piece of lava that emerged hot from a volcano in the year I was born, and a shell (46) _____ on my favourite childhood beach.
            Unlike everything else, from which memory and detail fades, it is as if the longer you hold on to certain objects, the (47) ________ their associations with the past become, and the sharper the recollections that gather around them. They are, (48) ________, real souvenirs, encapsulations not only of the place, but of your time in the place. But these days, the term “real souvenirs” sounds like a contradiction in terms, and this is because the objects sold to tourists as souvenirs are often cheap mass-produced imports that have nothing to do with the place at all.
            It’s often the (49) _____ that the best souvenirs, like my shell, are found rather than purchased, but browsing for souvenirs can also be a fun holiday activity. But if you are buying souvenirs on holiday this summer, make sure they (50) ________  the reality test. A good souvenir is not just made in the area where it is bought, it also says something about the culture of that area. It is something made by local people using sustainable local materials, and because you are effectively supporting the local economy, it shouldn’t come too cheap, either.

A.come across   
B.found out 
C. picked up

Read the following passage and mark the letter A, B, C or D on your answer sheet ton indicate the correct answer to each of the questions from 31 to 3.
Archaeological records paintings, drawings, and carvings of humans engaged in activities involving the use of hands indicate that humans have been predominantly right-handed for more than 5,000 years. In ancient Egyptian artwork, for example, the right-hand is depicted as the dominant one in about 90percent of the examples. Fracture or wear patterns on tools also indicate that a majority of ancient people were right-handed. Cro-Magnon cave paintings some 27,000years old commonly show outlines of human hands made by placing one hand against the cave wall and applying paint with the other. Children today make similar outlines of their hands with crayons on paper. With few exceptions, left hands of Cro-Magnons are displayed on cave walls, indicating that the paintings were usually done by right-handers.
Anthropological evidence pushes the record of handedness in early human ancestors back to at least 1.4 million years ago. One important line of evidence comes from flaking patterns of stone cores used in toolmaking: implements flaked with a clockwise motion (indicating a right-handed toolmaker) can be distinguished from  those flaked with a counter-clockwise rotation (indicating a left-handed toolmaker).
Even scratches found on fossil human teeth offer clues. Ancient humans are thought to have cut meat into strips by holding it between their teeth and slicing it with stone knives, as do the present-day Inuit. Occasionally the knives slip and leave scratches on the users` teeth. Scratches made with a left-to- right stroke direction (by right-handers) are more common than scratches in the opposite direction (made by left-handers). Still other evidence comes from cranial morphology: scientists think that physical differences between the right and left sides of the interior of the skull indicate subtle physical differences between the two sides of the brain. The variation between the hemispheres corresponds to which side of the body is used to perform specific activities. Such studies, as well as studies of tool use, indicate that right- or left-sided dominance is not exclusive to modern Homo sapiens. Populations of Neanderthals, such as Homo erectus and Homo habilis, seem to have been predominantly right-handed, as we are.
What does the author say about Cro-Magnon paintings of hands?
A.Some are not very old.
B. It is unusual to see such paintings.
C.Many were made by children.
D.The artists were mostly right-handed.
