1．Life on land probably began about 430million years ago，thought it had existed in the water for perhaps as long as 3，000million years．When we think of the first life on land，we probably think of strange animals coming out of the oceans，but，in fact，no animals could have been living if plants had not been on land first．Plants had to be on land before animals arrived．They supplied the first land animals with food necessary to live，since they-the plants are the only form of life that is able to get and store energy．
The first plants to exist out of the water were probably certain kinds of algae（海藻）which were followed by other plants that grew close to the ground near water and needed water in which to reproduce．Once the move to land had been made，however，evolution（进化）took place quickly．By the end of 100million years，plants had developed their roots，and some developed tall tree-like forms，since height was very important in competition for sunlight．About 300million years ago，much of the world was covered with forests of huge trees．
In most ways they were like modern trees．They had roots，leaves，wood，but mostly they had not developed seeds．

20．Once a New Zealand teacher asked where I live．"In the white building，"I answered．"At our university both girls and boys live in the same dormitory．"I added．Beyond my expectation（出乎意料），however，my attempt（努力）to show I am speaking American English（AE） turned out to be something else．The New Zealander seemed very puzzled（迷惑）at my answer．With a half smile，she asked，"Really？Do they live in the same room？""Oh，no．They live in different rooms but in the same building．"I reacted（反应）quickly．
Later I got to know the word"dormitory"．In AE it means one building，whereas（而，却）it means one room in British English（BE）．The New Zealander misunderstood me because she spoke New Zealander English（NE），which，as we know，is much related to BE．
Nowadays，not a few English learners，who try to catch up with the fashion（时髦），choose to speak AE．
Yet，the problem is that they cannot speak pure AE，but half AE and half BE instead．I think it necessary to keep one style in order to avoid（避免）misunderstanding．

19．Body and Food
Your body，which has close relations with the food you eat，is the most important thing you own，so it needs proper treatment and proper nourishment （营养）．The old saying"An apple a day keeps the doctor away"is not as silly as some people think．The body needs fruit and vegetables because they contain vitamin C．Many people take extra vitamins in pill form，believing that these will make them healthy．
But a good diet is made up of nourishing food and this gives all the vitamins you need．The body doesn't need or use extra vitamins，so why waste money on them？
In the modern western world，many people are too busy to bother about eating properly．They throw anything into their stomachs，eating hurriedly and carelessly．The list of illnesses caused or made worse by bad eating habits is frightening．
