It is important that pregnant women and those with poor immune systems become aware of the potential risks posed by cats.Many of us keep cats as house pets without realising the dangers they may be harbouring.Cats are hosts to infectious toxoplasma gondii,a protozoa that causes disease,toxoplasmosis,in mammals such as humans.The protozoa is crescent-shaped and common in nature,but in its infectious stage relies on cats as host bodies.Adult humans rarely show signs of significant disease if they become infected.However,if pregnant women become infected,the foetus can become infected by parasites and suffer serious congenital damage.In the worst cases,infants may lose their eye-sight and acquire motor dificits.In people with poor immune systems or AIDS.toxoplasmosis can cause seizeures and death.The symptoms of the disease are not evident in cats so there is no way of knowing if a particular cat is a risk.孕妇和免疫能力差的人群需要知道养猫的潜在致病风险。许多人养猫，却不知道猫可能带来危险。猫的身上会寄生具有传染性的刚地弓形虫，是一种能导致哺乳动物（比如人类），患上弓形虫病的原生动物。这种原生动物是新月形的，在自然界很常见，但它具有传染性的生命阶段是寄宿在猫身上。成年人在感染后极少显示出严重病症。但是孕妇被感染的话，胎儿可能被寄生虫感染，致使认知能力遭受严重损害。最严重可能导致婴儿失明，兼有运动神经缺陷。免疫力低或患有艾滋病的人群若患有弓形虫病，可能导致癫痫和死亡。猫患此病的症状并不明显，所以无法得知某一只猫是否感染。

This area has become well-known,but for unfortunate reasons.The junction（交叉处） of Green Road and Mill Street has been the site of over a dozen（十二） major road traffic accidents in the last five years as divers take the corner too quickly.A local artist has made a rather girm（恐怖的） photographic record of all the main accidents that have taken place.Some tourists have been victims（受害者）.New speed cameras（摄像头） have now been placed at the corner of road and this will reduce the number of accidents.这一地区变得声名远扬，不过不是因为什么好事。由于司机拐弯时速度太快，格林路和密尔路的交叉口在最近五年中发生了十起重大交通事故。当地一名艺术家用所有重大事故的现场照片做了一本相当恐怖的摄影集。有些游客也成了受害者。目前街角已经安装了新的车速摄像头，将减少交通事故。

Rights are either God-given or evolve out of the democratic process. Mostrights are based on the ability of people to agree on a social contract, theability to make and keep agreements.Animals cannot possibly reach suchan agreement with other creatures.They cannot respect anyone else’s rights.Therefore they cannot be said to have rights. 权利要么是天赐的，要么是民主进程的产物。大多数权利是建立在人们同意社会契约的能力之上的有达成并遵守协议的能力。动物是不可能到达的与其他生物的协议。他们不能尊重任何人的权利。因此，他们不能说拥有权利。

Optimus Prime and Bumblebee are Transformers. So obviously they are made of metal.擎天柱和大黄蜂都是变形金刚，所以，显而易见它们是用金属做的.
