【題目】 Dolphins are not fish. They are mammals (哺乳動(dòng)物). They live in groups and speak to each other in their own language. But they are quite different from almost all land animals. Their brain is as big as men’s and they live a long life--20 or 30 years.

Like some animals, dolphins use sounds to help them find their way around. They also use the sound to talk to each other and to help them to find food. They do not use their ears to receive sounds, but use the jaw - the lower part of the mouth.

It's strange that dolphins are friendly to men, and for thousands of years, there are many stories about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand, there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903, Jack met every boat in the area and showed it the way. In 1903 a passenger on a boat shot (拍照) a long time in the area. Jack guided the boat and helped it out.

Today many people still kill dolphins, but many countries in the world now protect them. In these places, people are not allowed to kill them.

【1】It's true that dolphins use ________.

A.noses to smell the wayB.ears to hear the sounds

C.eyes to see the wayD.sounds to find the way

【2】Jack was ________.

A.the writerB.a dolphinC.a seamanD.the passenger

【3】The dolphin guided the ships for about ________.

A.32 yearsB.9 yearsC.41 yearsD.23 years

【4】According to the passage, ________ is NOT true.

A.dolphins are not fishB.dolphins don't live in groups

C.dolphins are friendly to peopleD.dolphins can live a long life

【5】From the passage we can learn dolphins are ________.

A.uglyB.lazyC.cleverD.silly

【答案】

【1】D

【2】B

【3】A

【4】B

【5】C

【解析】

本文向我們介紹了海豚。海豚是一種哺乳動(dòng)物，它們的腦子和人類一樣大，壽命長(zhǎng)達(dá)20到30年，并且有其獨(dú)特的交流語(yǔ)言。海豚對(duì)人類很友好，在人類和海豚之間發(fā)生過(guò)很多故事，作者講述了19世紀(jì)一只叫Jack的海豚在海里為船只導(dǎo)航的故事�，F(xiàn)在有很多人還在捕殺海豚，但是很多國(guó)家現(xiàn)在采取措施保護(hù)它們，禁止捕殺它們。

【1】細(xì)節(jié)理解題。根據(jù)Like some animals, dolphins use sounds to help them find their way around.可知，海豚是通過(guò)聲音辨別方向的。故選D。

【2】細(xì)節(jié)理解題。根據(jù)In the 19th century, in a dangerous part of the sea near New Zealand, there was a dolphin. The seamen liked him very much and gave him a very good name, Jack.可知，Jack是生活在新西蘭附近海里的一只海豚，水手們都很喜歡他，并為它取名為Jack。故選B。

【3】細(xì)節(jié)理解題。根據(jù)From 1871 to 1903, Jack met every boat in the area and showed it the way.可知，Jack為那個(gè)區(qū)域的船只引路大約32年。故選A。

【4】判斷正誤題。根據(jù)文章開頭的Dolphins are not fish. They are mammals (哺乳動(dòng)物).可知，海豚不是魚，而是哺乳動(dòng)物，故A正確；根據(jù)They live in groups and speak to each other in their own language.可知，海豚是群居動(dòng)物，故B不正確；根據(jù)It's strange that dolphins are friendly to men...可知，海豚對(duì)人類很友好，故C正確；根據(jù)Their brain is as big as men’s and they live a long life--20 or 30 years.可知，海豚可以有很長(zhǎng)的壽命，故D正確。故選B。

【5】推理判斷題。句意：根據(jù)文章，我們可以知道海豚很聰明。A. ugly丑陋的，B. lazy懶惰的，C. clever聰明的，D. silly愚蠢的。根據(jù)海豚腦子和人類一樣大、可以用聲音交流并且為船只導(dǎo)航的故事，可以推斷出海豚很聰明。故選C。

這篇短文介紹了關(guān)于海豚的一些事實(shí)和故事。事實(shí)是海豚是哺乳動(dòng)物，壽命長(zhǎng)達(dá)20到30年，用聲音交流。故事是海豚對(duì)人類很友好，一只叫Jack的海豚在海里為船只導(dǎo)航大約32年。掌握了這些事實(shí)和故事，就可以做出細(xì)節(jié)理解題，也可以根據(jù)這些事實(shí)進(jìn)行推斷。如小題5，句意：根據(jù)文章，我們可以知道海豚很聰明。A. ugly丑陋的，B. lazy懶惰的，C. clever聰明的，D. silly愚蠢的。根據(jù)海豚腦子和人類一樣大、可以用聲音交流并且為船只導(dǎo)航的故事，可以推斷出海豚很聰明。故選C。

【題目】 You may not realize it, but you are doing much more than just studying when you are at school. School is also the place where you learn to get on well with people. But this is not always easy. What can you do if you just don’t like one of your classmates?

If you discover that you have problems getting on with your classmates or friends, the most important thing to learn is tolerance. Tolerance is the ability to realize and respect the differences in others. We can not change the way that other people do, so it is important to learn to live happily with them.

Tolerance will make everyone get on better with each other. Getting to know someone may help you understand why they do things differently. Something different does not exactly mean that it is bad. Tolerance teaches us to keep a temperate and open mind.

You need to remember an old saying, “Treat others how you want to be treated”. If you tolerate something, it does not mean that you have to like it. No one is asking you to change who you are or what you believe in. Tolerance just means that you should respect the differences in others and not try to make them change.

It is important to practice tolerance, because it will make everyone’s life easier. Learn to accept people for their different abilities and interests. The world is very different, and practicing tolerance in your own school and city can help make a difference.

【1】This passage is trying to tell us________ .

A.what’s important for a studentB.what students should do at school

C.how to treat people different from usD.how to get others to do things in the right way

【2】From the first paragraph we know that at school________.

A.it’s easier for someone to hate others

B.getting along with others is not a great deal

C.most students are getting on well with each other

D.students are learning other things besides studying

【3】What is tolerance according to the passage?

A.Accept people as they are.B.Believe you are always right.

C.Expect everybody to be the same.D.Change yourself to please other people.

【4】The last paragraph suggests that________ .

A.tolerance can only be learnt at school

B.living with people of the same interests is easier
