【題目】China ___________ (send) the 54th Beidou navigation satellite (導(dǎo)航衛(wèi)星) into space. It shows our fast development in exploring outer space.

【答案】has sent

【解析】

句意：中國已將第54顆北斗導(dǎo)航衛(wèi)星送入太空。它顯示了我們?cè)谔剿魍鈱涌臻g方面的快速發(fā)展。

從文字的表層意思推斷空格指中國已將第54顆北斗導(dǎo)航衛(wèi)星送入太空，表示已經(jīng)完成的動(dòng)作，用現(xiàn)在完成時(shí)，其謂語動(dòng)詞為has/have+過去分詞；主語China，助動(dòng)詞用has，send的過去分詞為不規(guī)則變化sent；故答案為has sent。

【題目】 Have you ever gone to a fast-food restaurant to eat and gotten a kid's meal that came with a toy? Sometimes those meals have different toys for boys and girls —maybe a truck for the boys and a toy bear for the girls. Who decides that boys like to play with trucks and girls like to play with stuffed animals? I know many boys who like stuffed animals and lots of girls who play with trucks. When we decide what someone will like or how they will act just because they are boys or girls, we are stereotyping（形成模式化觀念）.

A stereotype is a group that we put people into. Our human brains do this all the time; it's one of the ways that our brain has learned to deal with the world. We see someone and put that person into a group—for example, the old or the young, a boy or a girl. Is that a bad thing? No, it's not.

One advantage of a stereotype is that it enables us to deal with situations rapidly because we may have had a similar experience before. The use of stereotypes is a major way in which we simplify our social world; since they cut down the amount of processing（i.e. thinking）we have to do when we meet a new person.

Although grouping itself isn't bad, it can be harmful sometimes. It makes us ignore differences between each single person, that is, we usually think all the people in one group are the same but that might not be true.

When we stereotype, we think of a group and give everyone in that group certain characteristics. For example, the fast food restaurant believed that all boys like to play with vehicles and all girls prefer toy animals. They did that based only on whether they were boys or girls.

Stereotypes are problems when beliefs that people have about groups are not necessarily true. Have you ever heard anyone say that "Men are better drivers than women"? Statements like this take a group of people and give all of them the same behaviors or characteristics. I know men who are good drivers, and I know women who are good drivers. It's not fair to judge all people in a group by a stereotype. We need to remember that everyone in the group is an individual who has different abilities, interests, strengths and behaviors.

【1】The example of different toys for boys and girls is mentioned to show that_________.

A.boys and girls prefer different toys

B.boys and girls are treated unfairly

C.people sometimes mix children's likes

D.people have fixed ideas on things

【2】Which of the following stereotypes is useful?

A.Making friends by his appearance.

B.Boys do better in science than girls.

C.Youth easily do unreasonable things.

D.Red signs on the road warn us of danger.

【3】The underlined word “ignore” in Paragraph 4 probably means _________.

A.fail to noticeB.fail to trustC.fail to searchD.fail to face

【4】What does the writer want to tell us about stereotyping?

A.Stereotyping is like a coin which has two sides.

B.It helps our brain learn to deal with similar situations.

C.Judging people by stereotyping them makes things hard.

D.Trying to learn about and form some kinds of them stereotypes.

【題目】 Once upon a time, there was a king. He only had one leg and one eye, but he was very smart and kind. Everyone lived a happy and healthy life because of the king. One day, the king was walking through the palace hallway and saw the paintings of his ancestors(祖先). He thought that one day his children would also walk in the same hallway and remember all the ancestors through these paintings. He wanted his children to remember him, too. So he invited many famous artists to his palace.

All of the artists began to think about the king's physical disabilities. How could his painting be made very beautiful? It was not possible. They weren't sure what his painting would be like. So one by one, they all started to politely refuse to make a painting of the king.

But suddenly one artist raised his hand and said he would make a very nice painting of the king. The king became happy hearing that. Then the artist started painting. After a long time, the painting was ready.

When the artist showed the painting, everyone was shocked. In the painting, the king was sitting on a horse, on the one-leg side, holding his bow(弓箭)and aiming(瞄準(zhǔn))something with his one eye closed. The king was very happy and gave him lots of money.

As we all know, no one is perfect. So we should try to focus on(關(guān)注)others' advantages instead of their disadvantages. Just take an optimistic view(樂觀的觀點(diǎn))of the event. Everyone can do a good job.

【1】What did the king look like?
