Will you eat everything in your lunch box today? If not, will you save it for another time or just throw it away?

A recent study     1     (find) that 17% of all the food     2     (produce) around the world gets wasted each year,     3     reaches about 931 million tons. Believe it     4     not, 61% of the waste happens in our houses!

Food waste in homes     5     (happen) in rich countries like the US and the UK as well as in poor countries for different reasons.

Cultural habits could also lead to waste at home,       6     (include) massive packaging and “buy one, get one free” deals. ‘Use by’ or ‘best by’ dates       7     products could also cause people to throw away food. People could throw out food because they think it is     8     (safe) to eat, when in fact the date only shows when quality might go down.

Food was     9     (much) valued even in richer countries just a few generations ago, because people often couldn’t afford to waste it.     10     (throw) away food is for sure a great waste and we should try to make people know the importance of saving food.

The lion head is made with paper over a bamboo frame,       6     (cover)in gauze (纱布), and decorated with beautifully-colored materials.

The lion dance     7     (believe)to have first appeared in the Qianlong Emperor's dream during his Southern tour, and he ordered an animal     8     (make)in the likeness of his description and used in festivals from then on.

I love all about the lion dance. The other day, I saw a film about a left-behind teenager who insisted on pursuing his dreams despite difficulties and     9     (succeed)in lion dance. As Master Xu translates: “Heaven has made us talents; we’re not made     10     vain.”

Researchers in China     1     (show) an ancient skull to the world recently. The skull belongs to a     2     (complete) new species of humans that lived in China over 146, 000 years ago.
