1 – 2.Early humans used a material called 1…………………. to make the sharp points of their 2………………..
Key words: early humans, sharp points
In the first paragraph, the author mentioned that “From our earliest origins, man has been making use of glass. Historians have discovered that a type of natural glass – obsidian – … was first used as tips for spears”. “From our earliest origins” can be understood as “early humans”, “make use of” is the same as “use”, and “tips” means “sharp points”, so it can be inferred from the two sentences that our ancestors used obsidian to make the sharp points of their spears. Therefore, the answer for question 1 is “obsidian” and for question 2 is “spears”.
Man from our ealiest origins = early human
Tip = sharp point • Make use of = use
Answer: obsidian – spears
1. 4000 BC: 3……………………. made of stone were covered in a coating of man-made glass.
Key words: 4000 BC, made of stone, covered, coating, man-made glass
By using the skim and scan skill, we can locate the word “4000 BC” in the first paragraph: “Archaeologists have even found evidence of man-made glass which dates back to 4000 BC; this took the form of glazes used for coating stone beads”. Here, “this” refers to “man-made glass”, and “coat” means “cover”, so the sentence
can be paraphrased into “man-made glass was used to cover the stone beads”. The answer is “beads” (note that only one word is allowed)
Coat = cover
Answer: Beads
