分析 本文主要講述了電子煙產(chǎn)生的原因,它的特點,危害及優(yōu)點;文中講到:由于吸煙會導(dǎo)致死亡,所以就有制造商生產(chǎn)了比香煙要安全一些的電子煙;這種電子煙像香煙一樣含有尼古丁,但它們不使用煙草;它們使用電池,所以也不用將它們點燃;盡管電子煙相對與真正的香煙要安全,但是由于它里面含有液體尼古丁,再加上美國聯(lián)邦政府也沒有控制它們的使用,使得美國的5歲或是更小的兒童沾染上了電子煙,因此它對于兒童也是不安全的;美國疾控和預(yù)防中心的吸煙與健康辦公室主任Tim McAfee在文中介紹了液體尼古丁的危害,如:當(dāng)這種物質(zhì)進(jìn)入皮膚,進(jìn)入眼睛或被吞咽的時候,就會發(fā)生尼古丁中毒;即使是少量的尼古丁,也能使一個人生病;尼古丁中毒可引起胃部疼痛或不平衡感,頭痛和突發(fā)疾病,過量的使用尼古丁還會導(dǎo)致死亡;但是由于電子煙不含有在真正的香煙中發(fā)現(xiàn)的數(shù)百種的有害化學(xué)物質(zhì),所以美國衛(wèi)生局長建議電子煙可以成為成年人試圖戒煙的一種有用的工具;Tim McAfee認(rèn)為電子煙雖然并沒有像真正的煙制品那樣創(chuàng)造了風(fēng)險等級,但是他也擔(dān)心青少年會認(rèn)為電子煙是無害的,會對尼古丁上癮,然后開始吸真正的香煙.
解答 答案:
33.them 考查人稱代詞 根據(jù)上文"E-cigarettes contain the drug nicotine like cigarettes.But they do not use tobacco."介紹了電子煙像香煙一樣含有尼古丁,但它們不使用煙草;可推測出本句的意思應(yīng)是:你也不用將它們點燃;因此這里是為了避免重復(fù),使用了"它們"來代替前面的E-cigarettes;由于此處在句中作動詞light的賓語,故填them
34.in 考查介詞 本句的意思是:為什么美國各地的毒物控制中心看到了關(guān)于電子煙中毒的電話在增加;因此這里指的是:在…方面有增加;故填in
35.a(chǎn)ged 考查過去分詞 此處在句中作后置定語,修飾前面的名詞children;動詞age與該名詞構(gòu)成動賓關(guān)系,意為:(長到)5歲大的孩子;故填aged
36.even if/even though 考查從屬連詞 本句的意思:他說,問題在于監(jiān)管,即使電子香煙里含有液體尼古丁,聯(lián)邦政府也沒有控制它們;本句是一個讓步狀語從句,故填even if/even though"即使,盡管"
37.when 考查從屬連詞 分析句意可知,此處在句中作時間狀語;意為:當(dāng)這種物質(zhì)進(jìn)入皮膚,進(jìn)入眼睛或被吞咽的時候,就會發(fā)生尼古丁中毒;故填when
38.can 考查情態(tài)動詞 分析句意可知,此處講的是尼古丁產(chǎn)生的危害,即:即使是少量的,也能使一個人生病;故填can
39.that/which 考查關(guān)系代詞 根據(jù)句意"電子煙不含有在真正的香煙中發(fā)現(xiàn)的數(shù)百種的有害化學(xué)物質(zhì)"可知,本句是定語從句;先行詞 hundreds of harmful chemicals(數(shù)百種的有害化學(xué)物質(zhì))指物,在從句中作主語,故填taht/which
40.trying 考查現(xiàn)在分詞 分析句意可知,此處在句中作賓語 adults的補足語,并且賓語 adults與動詞try構(gòu)成了邏輯上的主謂關(guān)系;故填trying
點評 本題主要考查了各種語法在短文中的具體運用.做本題時,需要在正確理解短文的前提下,逐句分析句意以及所考查到的語法現(xiàn)象;因此在平時的學(xué)習(xí)中,應(yīng)熟練掌握各種語法知識,其中包括詞法,句法,各種時態(tài)語態(tài)以及虛擬語氣等.

A student walks into his first class and realizes he forgot all about the midterm exam. He knows he needs to bring his grades up, and getting a zero will make it nearly impossible. He quickly jots down some notes and shoves them under his lap hoping it will help him pass. Cheating is a major concern in all academic environments. Students are creating new and more outrageous(令人吃驚的)ways of cheating every day: some claim that certain accounts of cheating can be justified, but overall it can always be prevented.
Cheating has been around forever, and millions of ways to cheat have been fashioned. Copying homework and cheat sheets are some of the most basic ways students in all education levels have cheated. Some students think nothing about writing a few answers on their hand, in a gum wrapper, or boldly using a study guide to cheat. Desperate students have even gone as far as to steal the test or scan in bottle wrappers and put answers into the nutrition label. The internet has now become available in almost every location. Computers can be accessed at school, at home, and now even on cell phones. This opens a doorway for even more methods of cheating to be born.
There are countless opinions on whether or not cheating can be justified. The truth is this behavior will always be a matter of opinion with each scenario of cheating. Students often rationalize their cheating by claiming they forgot to look over the material or did not understand what the teacher or professor was saying. Some may counter these arguments by saying that the student could have set reminders or asked the teacher to explain the material before the day of the test. Some other reasons students believe cheating is justified are their heavy workloads and trying to find time for school, sports, friends, and family. This may be true in certain instances, however, all students have these problems, and it is unfair to the students refrain(制止) from cheating when the student who is dishonest receives a better grade. The majority of students who think cheating is acceptable may believe the reason for this is that sometimes students are unaware they are cheating, there is not enough time given for assignments, or that the information is too much for the course.
It may be difficult to accomplish, hut cheating can be prevented. 1'eachers and professors have tried many options to stop cheating. These options can range anywhere from simply spreading test-takers out in a room, to expelling(驅(qū)逐)a student, which will most likely hinder their plans of getting into another college. One simple way to fix the problem is to scold the student when caught. They may be so scared or embarrassed that they never do it again. This is a risky way to prevent cheating in some cases, however, because it can possibly damage self-esteem. Another simple way 10 avoid cheating is to create many different kinds of the same test. This prohibits students from getting the answers off of a neighbor's test, but students still have the option of using other cheating tactics.
There may be a million ways to cheat and get away with it, but there are few times, if any, that it is justified. Cheating never has to be a necessity and is never worth compromising morals and losing years worth of working towards a degree. This problem is spreading throughout America; with everyone's help, it can be stopped.
