课时跟踪练(三) Lesson 2 & Lesson 3 — Pre-reading Ⅰ.阅读理解
A
The idea of cloning your pet sounds like a laughable waste of money, because it is.But it starts to seem a little less laughable when your own beloved pet starts getting older.If I had had a few hundred thousand dollars to spare, I know I would have half­seriously considered it for my dear little cat, who died last year.One couple that does happen to have a few hundred thousand dollars to spare is Barry Diller and Diane von Furstenberg, who have reportedly cloned their beloved Jack Russell Terrier (a kind of dog), Shannon, and now have two identical Jack Russell Terriers, named Deena and Evita.
When your pet dies, you just want your pet back, or at least
as close a copy as you can get.So it's really no surprise that
of the around 600 dogs cloned by Sooam Biotech Research
Foundation most were cloned for sad pet owners.The lab in Seoul, South Korea, is now the only place on the planet in the business of cloning pet dogs for owners.
But, in fact, the technology won't give you your pet back.There don't yet appear to be any studies on the behavior of cloned pets, but research on cloned cows and pigs has so far shown marked differences in behavior and even looks in cloned animals.The DNA is exactly the same, but there are still differences in personality and appearance.
Even if Diller and von Furstenburg raise their new dogs in the exact same environment in the exact same way that they raised Shannon, the new dogs will still behave differently.“The promise of pet cloning is that your cloned pet is going to behave and look like the one you already have —and that will not be the case，〞said Professor Jorge Piedrahita at N．C.State.“We've cloned animals that were raised in the same environment, but they still didn't act the same.〞

I am a member of the Young People's Chorus (YPC) of New York City.The chorus is made up of children aged 8 to 18.I've been in the chorus for almost five years, and I love the community of “you ng artists.〞 Every year, we give a big performance to raise money for the organization.It's the biggest concert of the year and is held at Lincoln Center.A lot of work goes into the final performance.
First, we begin learning our music.We usually start by learning the notes, and then we add the words.Someone comes in to teach us the meaning and pronunciation of the lyrics (歌词) if the words are not in English.
Next, we memorize the whole song, even if we only sing part of it.One of the hardest pieces we sang this year was Tjak！， a song inspired by a Balinese Monkey Chant.It has four parts, each with a different rhythm.
Once we add dynamics (力度变化) to our songs to give them life, it's time to add choreography.Jacquie Bird, the director, tells us to connect the words we sing to our movements as we breathe and count in our heads.
As we get closer to the concert night, the rehearsals (彩排) get tougher.Sometimes, we do a quick review, and sometimes we sing the whole song.My knees and arms start to ache.But once we get a break and some food, we come back feeling better.We rehearse on weekends for almost a month beforehand; every moment is important and worth it.
The real excitement comes during the rehearsal, when we meet our guest artists.This year, YPC invited Mandy Gonzales, Alexandra Socha, and Time for Three to join us.After hearing that we would work with them, we jumped up and down backstage as quietly as we could.
Showtime！We sang with musical guests and performed dances that seemed as if they came straight from a Broadway show.At the end of the night, we screamed with excitement backstage.For all of us, pulling off the biggest performance of the year felt great.

A．To collect money for YPC.
B．To pick excellent performers.
C．To show kids' talent for acting.
D．To celebrate the success of YPC.
解析：选A 细节理解题。

由第一段中的“Every year, we give a big performance to raise money for the organization.〞可知，每年一次的大型表演是为YPC筹集资金。

6．What does the underli ned word “choreography〞 in Paragraph 4 mean?
A．Lyrics. B．Games.
C．Videos. D．Dances.
解析：选D 词义猜测题。

由画线词之前的“Once we add dynamics to our songs〞和画线词之后的“connect the words we sing to our movements as we breathe and count in our heads〞可知，为了使歌曲富有活力，需要增加舞步。

7．What excites the author most during the rehearsal?
A．Getting a rest after tough hours.
B．Working with Jacquie.
C．Meeting guest artists.
D．Having some food.
解析：选C 细节理解题。

由倒数第二段中的“The real excitement comes during the rehearsal, when we meet our guest artists.〞和“After hearing that we would work with them, we jumped up and down backstage as quietly as we could.〞可知，能结识特约嘉宾让作者感到非常兴奋。

8．How did the author feel at the end of the concert night?
A．Shocked. B．Regretful.
C．Thankful. D．Overjoyed.
解析：选D 推理判断题。

由最后一段中的“At the end of the night, we screamed with excitement backstage.〞可知，表演完毕之后，作者和同伴们欣喜假设狂。

Gallery A: Photographs of Traditional West African Architecture
This section shows historical and contemporary photographs of traditional West African architecture.Of particular interest are the photographs of the Dogon village.The design of the Dogon village is based on the human figure.Certain types of buildings are placed in particular areas according to the Dogon's complex philosophical (哲学上的) tradition.For example, the men's houses are placed in the “head〞of the village, the leader's house is in the “chest，〞 and the women's houses are in the “hands.〞

Ⅱ.阅读七选五
When we're struggling with something, it's natural to turn to others for help.Helping each other is a part of the giving and receiving that makes up good relationships.Getting help sounds simple.But it's not always easy to do.__1__ Here are some examples of the kinds of attitudes that can stand in the way and ideas on how to get past them.
Obstacle (障碍) 1：__2__
Asking for help shows confidence.It's a sign of strength, not weakness.You know what you need and you're not afraid to reach out for it.
For example, instead of thinking: I don't want my coach to find out I can't learn that move well in case he thinks I shouldn't be on the team.Change it to: I'll show
my coach how committed (效忠的) I am to the team and how hard I practice by asking him to share tips on how I can improve.
Obstacle 2: Thinking you don't deserve help or support.
Everyone needs help now and then.__3__Accepting help can strengthen friendships and relationships.Everyone feels good when they can support a friend.
__4__ Share your feelings or a problem with someone who listens and cares, not someone who judges, criticizes or blames you.Most of the time we can guess in which way people might react, but on rare occasions, they catch us off guard (让我们猝不与防)．__5__ It's what's going on with the other person.
A．Be careful with the friends you are making.
B．Be careful in choosing who you ask for help.
C．No one can or should handle everything alone.
D．Believing that needing help is a sign of weakness.
E．Sometimes we stand in our own way without realizing it.
F．If you do get rejected, it's not because of anything you did.
G．Convincing yourself that needing help is a sign of strength.
的事情，有时候是我们自己阻碍了寻求帮助的道路，但是我们却没有意识到这一点。

E项的“stand in our own way〞与下句“stand in the way〞呼应。

2．选D 由下文“It's a sign of strength, not weakness.〞可知，此处指的障碍是“我们有时候认为寻求帮助是懦弱的表现〞。

由本空前“Obstacle〞可知，G项错误。

3．选C 由上句“Everyone needs help now and then.〞可知，每个人都有需要帮助的时候，没有人能够或者是应该独自处理一切事情。

4．选B由空后“someone who li stens and cares, not someone who judges, criticizes or blames you〞可知，此处是指“找到适宜的可寻求帮助的对象才行〞。

5．选F 由空后“It's what's going on with the other person.〞可知，当我们被拒绝的时候，不是因为我们自己做错了什么事情，而是因为我们找错了求助对象。
