【题目】根据短文内容，选择最佳答案。
What will people die of 100 years from now? If you think that is a simple question，you have not been paying attention to the revolution that is taking place in bio-technology（生物技术）. With the help of new medicine，the human body will last a very long time. Death will come mainly from accidents，murder and war. Today's leading killers，such as heart disease，cancer，and aging itself，will become distant memories.
In discussion of technological changes，the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells（细胞） are the basic units of all living things，and until recently，scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells，such as those of brain cells，would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100，medicine will have advanced to the point at which every 10 years or so，people will be able to take medicine to repair their organs（器官）. The medicine，made up of the basic building materials of life，will build new brain cells，heart cells，and so on－in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence，but many technical problems still must be cleared up on the way to this wonderful future.
（1）According to the passage，human death is now mainly caused by ________.
A.diseases and aging

（4）How long can humans live in the future according to the passage?

For teenagers, it's great fun to explore new places and it feels like an adventure, even when you know you're not the first to have been there. But to make sure not to get lost or waste time going round in circles, the following tips may be helpful.
◆Do the map reading if you're being driven somewhere. It'll be easier if you keep the map following the direction you are traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you'll have to move to the back seat.
◆Get a group of friends together and go exploring. You'll need a good map, a compass, a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies. Tell someone where you're going before you set out and let them know what time you expect to be back. The purpose of the activity is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.
◆See if your school or a club organizes orienteering(越野识途比赛) activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B(and B to C, etc. ) in the fastest time, or simply as a spare-time activity. It enables you to be familiar with the use of maps and compass and gain some special skills. In some way, it's not only good fun, but also a great way to keep fit.

A.look ahead to see where there is a gas station

I was tired and hungry after a long day of work.
When I walked into the living room, my 12 -year-old son 1 up at me and said, “I love you.” I didn't know what to say. For several 2 , all I could do was to 3 there and looked down at him.

“Nothing.” He said, “My teacher said we should 6 our parents that we love them and see what they say. It's 7 .”

I don't know if saying that made either of us healthier, but it did feel pretty good. Maybe next time one of my children says, “I love you.”, it would not take me a whole 19 to think of the right 20 .
