[1]People visit other countries for many reasons.Some travel on business;others travel to visit interesting places that are only found in other countries,such as the Taj Mahal (泰姬陵)in India,or the temples of Thailand.

[2] Wherever you go, and for whatever reason,it is important to be safe.A tourist can attract a lot of attention from local people.While the majority of people you will meet when traveling are sure to be friendly and welcoming, there are dangers—theft being the most common.Just as in your home country, do not expect everyone you meet to be friendly and helpful.It is important to prepare for your trip in advance, and to take precautions while you are traveling.

[3] As you prepare for your trip, make sure you have the right paperwork.You don't want to get to your destination only to find you have the wrong visa,or worse,that your passport is about to expire.Also, make sure you travel with proper medical insurance, so that if _________________ during your travels,you will be able to get treatment.If you want to drive while you are abroad,make sure you have an international driver's license.

[4]Buy a guidebook and read about the local customs of the country you are going to.Also, try to learn a few basic words and phrases—don't assume that the local people will speak your language.

[5]When you get to your destination, use official transport.Always go to bus and taxi stands; don't accept rides from strangers who offer you a lift.If there is no meter in the taxi, agree on a price before you get in.If you prefer to stay in cheap hotels while traveling,make sure you can lock the door of your room from the inside.If you are traveling with valuables such as jewelry, or a lot of cash, you should ask about a safe for storing them in.Finally, remember to smile.Smiling is the friendliest and most sincere form of communication, and is sure to be understood in any part of the world!

阅读下面文字,完成文后四题。

最近,天文学家在距地球至少110亿光年的宇宙深处发现,众多的新星正在早期星系内快速生成。若进一步的研究能够核实那些星系的实际年龄的话,则这一新研究的成果将意味着星系诞生的高峰期远较人们以前确认的年代为早,星系生成的速度也大大高于从前的估算,宇宙早期的演化史可能需要科学家们去重新认识。

确定大量星系生成的年代对于加深了解宇宙的起源和演化具有十分重要的意义,而科学家们也一直在宇宙深处不断搜寻亿万恒星的孕育之处。然而,由于形成恒星的区域常常笼罩有浓重的星际尘埃,掩蔽了新星发射的可见光及红外辐射,而距离更远的恒星和星系所发出的辐射传到地面时已属于信号极其微弱的亚毫米波段,探测难度相当巨大。

科学家们报告说,他们探测到了与哈勃太空望远镜照片上5个古老昏暗的星系相对应的亚毫米波辐射源,并根据辐射波的强弱特点判断,这些早期的星系可能正在以高于银河系100倍的速度缔造新的恒星。

目前,天文学界普遍认为,星系大部分形成于宇宙诞生后的80亿~100亿年间,但新的发现却清楚地显示,星系可能早在宇宙处于20亿年的早期阶段就已经大量涌现了。

天体物理学家佩蒂尼评论说,新的发现是非常令人振奋的科学进展,有助于解答宇宙是如何从热大爆炸后的初期平稳阶段演变为今日所见的浩繁星系的。

下列说法不符合原文意思的一项是()。

A.科学家们发现,宇宙深处的早期星系内生成的新星,其生成速度大大高于从前的估算。

B.哈勃太空望远镜照片上的5个古老昏暗的星系是众多新星正在快速生成的早期星系。

C.正在早期星系内快速生成的大量新星是恒星。

D.新的发现可能要将对星系诞生的高峰期的推算提前60亿—80亿年。
