SARS与流感病毒

医学研究人员正试图通过研究与SARS病毒类似的变异流感病毒,找出战胜SARS的方法。但每年都会出现新的变异后的流感病毒,它们使正在使用的抗流感疫苗成为废品。这使病毒学家感到焦虑,担心即将出现的流感病毒会导致1918年西班牙全国性流感造成的惨剧,当时,全球至少有2000万人死于这场流感。因此,尼尔·弗格森在英国皇家学院制造了一个生物模型,试图通过开发这个精确的仿真模型解释流感病毒的变异是怎样产生的。他认为这一研究可以找出增强人类免疫系统的方法。

流感病毒的迅速变异使科研人员迷惑不解,然而自然界中存在的流感病毒寿命却并不长。弗格森的合作者、加利福尼亚大学的分子进化论学家罗宾·布什说:“大多数新的病毒变种会很快消失。”但是为什么流感病毒总是卷土重来反复感染呢?通过对模型的研究,布什和弗格森在病毒变种和人体免疫系统的相互影响中找到了答案。研究人员的研究集中在一组含多糖蛋白质分子的病毒上,通过对它们的研究就可以了解人体的免疫系统如何能识别入侵的病毒。这些分子的变化是病毒发生变异的原因,病毒变异使人体内不能迅速形成新的抗体,也致使原有的疫苗失效。

这个模型显示出,短期内,免疫系统对发生巨大变化的流感病毒不会产生明显的反应。布什说:“这证明了,在一般情况下,感染流感病毒两周后,免疫系统才能对病毒产生反应。”大多数病毒的变种都是在旧病毒消亡之初产生的。但是,新病毒在感染宿主后,很难继续存活,病毒变异也会因此终止,然后,这种变异的流感病毒就会取代旧的流感病毒在人群中传播。如果研究人员能够发现及时抑制病毒的方法,就可以开发并设计出提供免疫系统长期使用的疫苗。弗格森正配合计算机模型研究引起SARS的冠状病毒,一旦科学家收集到相同菌株的数据、传输速率和免疫反应,这个模型同时也就揭示出SARS病毒的弱点。

7.阅读文章第一段,对“使病毒学家感到焦虑”的原因理解正确的一项是

A.由于流感病毒的变异,目前尚无法找到适当的与SARS病毒类似的变异流感病毒以供进行研究。

B.与SARS病毒类似的流感病毒每年都会出现新的变异,使正在使用的所有抗流感疫苗成为废品。

C.由于流感病毒的变异,即将出现的SARS病毒会导致类似1918年西班牙全国性流感造成的惨剧。

D.目前正在使用的抗流感疫苗,会因为流感病毒每年都会发生变异产生新的种类,因而成为废品。

8.阅读文章第二段,根据自己的理解和推断,在下面标序号处应填写的内容,恰当的一项是

A.①原有疫苗失效       ②流感病毒发生变异     ③免疫系统无法识别

④不能迅速形成新抗体

B.①流感病毒发生变异   ②不能迅速形成新抗体   ③免疫系统无法识别

④原有疫苗失效

C.①流感病毒发生变异   ②免疫系统无法识别     ③不能迅速形成新抗体

④原有疫苗失效

D.①不能迅速形成新抗体 ②流感病毒发生变异     ③免疫系统无法识别

④原有疫苗失效

9.对于“流感病毒卷土重来”的原因,分析正确的一项是

A.人体免疫系统对发生巨大变化的流感病毒不会产生明显的反应。

B.大多数病毒的新的变种,都是在旧病消亡后的最初时期产生的。

C.在感染宿主的体内,新病毒被迫终止变异,转而向广大人群传播。

D.原有的流感病毒被变异了的新的流感病毒所取代,向人群中传播。

10.根据文章,下列推断不合理的一项是

A.坚持对与SARS病毒相类似的变异的流感病毒进行研究,医学研究人员才有可能找出战胜SARS的途径和方法。

B.尼尔·弗格森开发的仿真生物模型研究的对象,应该是与引起SARS的冠状病毒相类似的变异了的流感病毒。

C.病毒的变种可以突破人体免疫系统,而人体免疫系统一旦产生反应,又可将其置之门外:二者是对立的统一。

D.感染宿主后很难存活,变异随之停止,是SARS病毒的弱点之一,因而宿主体内的提取物是研制疫苗的重要研究对象。

     Sure, it’s good to get along with your teacher because it makes the time you spend in the classroom

more pleasant.

     And yes, it’s good to get along with your teacher because, in general, it’s smart to learn how to

relate to the different types of people you’ll meet throughout your life.

     But really, there’s one super-important reason why you should get along with your teacher. When

you do, “learning bursts right open,” says Evelyn Vuko, a longtime teacher who writes an education

column called “Teacher Says” for the Washington Post newspaper.

     In fact, kids who get along with their teachers not only learn more, but they’re more comfortable

asking questions and getting extra help. This makes it easier to understand new material and do your

best on tests. When you have this kind of relationship with a teacher, he or she can be someone to

turn to with problems, such as problems with learning or school issues, such as bullying(欺负人).

     As a kid in a primary or middle school, you’re at a wonderful stage in your life. You’re like a

sponge(海绵), able to soak up lots of new and exciting information. On top of that, you’re able to

think about all this information in new ways. Your teacher knows that, and in most cases, is very

excited to be the person who’s giving you all that material and helping you put it together. Remember,

teachers are people, too, and they feel great if you’re open to what they’re teaching you. That’s why

they wanted to be teachers in the first place --- to teach!

     Some kids may be able to learn in any situation, whether they like the teacher or not. But most

kids are sensitive(敏感的) to the way they get along with the teacher, and if  things aren’t going

well, they won’t learn as well and won’t enjoy being in class.

1. In the passage, the teacher mainly talks about _____.

    A. how to get along well with teachers

    B. the importance of a good relation with teachers

    C. how much the students are expected of to get along with teachers

    D. how to make the time in the classroom more pleasant

2. “Learning bursts right open” in the third paragraph really means _____.

    A. learning becomes easier for you at once    

    B. you find an opening to learning    

    C. there’ll be more problems with learning    

    D. there’ll be no problems with learning.

3. According to the passage, which of the following offers the best reasoning?

    A. You are getting on well with your teachers, so you have more questions than others.

    B. You find it comfortable to ask questions, so you can build a good relationship with teachers.

    C. You have a good relationship with teacher, so you can turn to him/ her when in trouble.

    D. You are in trouble, so you can build a good relationship with teachers.

4. Which of the comments is FALSE on teachers and their work according to the passage?

    A. Teachers are exited even if you wouldn’t like to accept their teaching.

    B. Teachers sometimes have the same feelings as students do.  

    C. Though few there are still some students who can learn even if they don’t like the teacher.

    D. Having a bad relationship with your teachers does more or less harm to your studies.
