14．I got invited to go with some friends to a game at another school．A senior will be driving us，and I think she's a good driver，but it's someone my parents don't know．I want to tell my parents where I'm going，but what if I ask and they say"no"？I'll end up wishing I never mentioned it and just went ahead and did it anyway．
If you want permission，it's best to build a track record of honesty and trust．Letting a parent know where you're going is always a good idea．
You may worry that telling your parents puts you at risk of getting"no"for an answer．But there's a good chance your parents might be OK with you going．If you go but don't tell them，you risk losing something more important-your parents'trust．
Parents who find out their kids did something behind their backs may be less likely to give permission to do things in the future．When trust is broken like this，parents wonder if teens are trying to hide something-and what they imagine can be far worse than the reality．
Before you talk to your parents about the game，think about which approach will help them feel most comfortable with giving you more freedom．Maybe they'd like to meet the person driving or talk to friends who have driven with her in the past．If your parents have questions or hesitate about letting you go，find out what their worries are and then do your best to answer them．

4．The African elephant，the largest land animal remaining on earth，is of great importance to African ecosystem（生态系统）．Unlike other animals，the African elephant is to a great extent the builder of its environment．As a big plant-eater，it largely shapes the forest-and-savanna（大草原）surroundings in which it lives，therefore setting the termsof existence for millions of other animals that live in its habitat．
It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat．In its continuous search for the 300 pounds of plants it must have every day，it kills small trees and underbushes，and pulls branches off big trees．This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas．In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters．
Take the rain forests for example．In their natural state，the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor．By pulling down trees and eating plants，elephants make open spaces，allowing new plants to grow on the forest floor．In such situations，the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well．
What worries scientists now is that the African elephant has become an endangered species．If the elephant disappears，scientists say，many other animals will also disappear from vast areas of forest and savanna，greatly changing and worsening the whole ecosystem．

29．What is the passage mainly about？B
A．Disappearance of African elephants．
B．The effect of African elephants'search for food．
C．Forests and savannas as habitats for African elephants．
D．The eating habit of African elephants．
30．What does the underlined phrase"setting the terms"most probably mean？C
A．Worsening the state．
B．Improving the quality．
C．Deciding the conditions．
D．Fixing the time．
31．What do we know about the open spaces in the passage？A
A．They are attractive to plant-eating animals of different kinds．
B．They result from the destruction of rain forests．
C．They provide food mainly for African elephants．
D．They are home to many endangered animals．
