【題目】Evolution (進化) has changed our bodies and faces over thousands of years, and it’s still happening. Here’s how experts predict (預測) what people will be like in 1,000 years.

We’ll be about 1.83~2.13 metres tall because of improved nutrition (營養(yǎng)) and medical science. Our arms and fingers will get longer to reduce the need to reach too far.

We’ll have smaller brains, maybe because computers will help us memorize and think most of the things.

There will be larger eyes and smaller mouths. And there may be fewer teeth as softer food needs less chewing and biting. We could even get our nutrition from liquids or pills in the future.

We can expect other great changes too. Everyone will have the same shape of noses. That’s because climate will have less influence on noses with the help of air conditioning and central heating. Besides, we will have more wrinkles (皺紋) as a result of looking at our electronic devices.

We also may end up with saggy (松弛的) necks because extra sun will cause loose skin. And there will be darker skin as people move around the planet and races (種族) mix.

根據(jù)材料內(nèi)容選擇最佳答案，并將其標號填入題前括號內(nèi)。

【2】 How will we usually memorize and think?

【3】What kind of food will we probably eat in 1,000 years?
