This is the year 2070. Today is my    1     (fifty) birthday, but I look like a person of eighty- five. I have serious kidney (肾脏) problems because I don’t have enough water     2     (drink). I’m afraid I don’t have much time left to live. I’m already one of the oldest people in this society.

I remember when I     3     (be) five years old, everything was very different. There were lots of trees in the parks. I could enjoy a shower for half     4     hour. At that time,     5    (woman) all had beautiful hair. Now, we have to shave (剃光) our heads to keep them clean without the use of water.

I remember there were “Saving Water” warnings in many public places, but nobody     6     (pay) attention. We believed water would last forever. Now, all the rivers and lakes are either dry or polluted. Water is much     7     (expensive) than gold and diamonds.

In the past, doctors suggested adults drink eight glasses of water a day. Nowadays, I am allowed half a glass only. Most people are weak and sick.

When my son asks me about my childhood, I tell him about how pleasant it was to fish in the rivers     8     how healthy people were. When he asks, “Why is there no clean water now?” I feel guilty (有罪的). I belong     9     those people who simply turned a blind eye to all the warnings.

I hope the people living in the 2020s     10     (true) understand the importance of saving water.

It is common     7     (give) guests a cup of tea to welcome them into the home. But tea is more than a key of social customs. It is meant to act     8     a medium through which people can become much     9     (close) to nature. Drinking tea out in nature will create a spiritual connection to the environment and make people feel     10     (relax).

The new regulation, which is set to fill the legal gap for domestic intelligent connected vehicles, said automakers don’t     4     (necessary) have to equip fully autonomous vehicles with manual driving mode and corresponding (相应的) devices, and nor do they have to have human drivers.

But such fully autonomous vehicles can only drive on certain roads and sections     5     (select) by Shenzhen’s traffic management department, according to the regulation, which was published on the official website of Shenzhen Municipal People’s Congress.

The regulation classified autonomous vehicles     6     three types: conditionally autonomous driving, highly autonomous driving, and fully autonomous driving. Conditionally autonomous and highly autonomous vehicles must have manual driving modes and corresponding devices, and     7     (equip) with drivers.

Meanwhile, the regulation     8     (clarify) rules for responsibilities and auto insurance coverage in the event of car accidents     9     involve autonomous driving, which is expected to promote the fast     10     (develop) of self-driving vehicles.

It is very old and full of meaning. Everything must be done in a special way in the ceremony. There is even a special room for it in their houses.
