Computer mouse is no longer so strong. A Canadian engineer has invented a system that enables a computer user to push a cursor（光标）across a screen simply by moving his or her nose .He calls his nose-driven mouse a mouse.

The inventor ,Dmity Gorodnichy ,came up with the idea for the mouse while building computer software that would help astronauts operate the Canadarm—a long robotic arm on the U.S. space shuttle .His system employs a web-camera that recognizes a computer user’s nose from 25 pixels ,or points of light. Dmity chose the nose because its position remains relatively constant no matter which way the head moves .The system keeps track of the pixels, and the user matches the movements of his or her nose with the progress of the cursor across the screen.

The mouse keeps track of the eyes too. Two blinks（眨眼）are a “double click,” which turns the mouse on or off.

The mouse has received mixed comments from those who hold opposite opinions. One called it “a pointless waste of technology” . Another predicted that the nouse will fail to catch on because it makes users “look silly.” Dmity has already adapted the nouse for NousePong, a video game ,and NousePaint ,a drawing program.

He also predicts that the mouse will attract the people who have suffered from specific disease-pain ,senselessness ,or trembling in the hand caused by the frequent repetition of movements of the wrist and fingers ,such as typing at a computer keyboard .His next plan is to adapt the nouse for use by paralyzed（瘫痪）patients in hospitals .With two blinks of the eyes ,patients could double-click for help.

72．The best title for this passage is probably      .

A．Mouse Driven by Nose

B．Cursor Moved Without fingers

C.New Computer System for Astronauts

D．New Type of Mouse for Patients

73．The nouse is a system working by means of          .

A．keeping track of the points of light

B．moving one’s nose or blinking

C.moving cursor across the screen

D．matching the user’s nose with eyes

74．The underlined phrase “catch on” means “       ”.

A．become popular     B．be used      C.get improved        D．be made

75．Dmity predicts that the nouse will be more used to help          .

A．those who have eye trouble

Our planet is in trouble．Polluting industries and corporations are destroying our planet, resulting in increasing global temperatures, melting ice caps, and economic turmoil（混乱）．All across the country, folks are waking up to the reality that if they do not ad now to solve the environmental problems of today, the consequences are unthinkable．If we don't i ct now, who will?
