Jane was walking round the department store. She remembered how difficult{#blank#}1{#/blank#} was to choose a Christmas present for her father. She wished that he was easy {#blank#}2{#/blank#}(please). Besides, shopping at this time of the year was not {#blank#}3{#/blank#}pleasant experience: people stepped on your feet or {#blank#}4{#/blank#}(push)you with their elbows, hurrying ahead to get to a bargain.

    Jane paused in front of a counter (柜台) {#blank#}5{#/blank#} some attractive ties were on display. But Jane knew from past experience that the {#blank#}6{#/blank#}(choose)of ties hardly ever pleased her father.

    Jane stopped where a small crowd of men had gathered. She found some good quality {#blank#}7{#/blank#}(pipe) on sale. She did not hesitate for long: although her father smoked a pipe only once {#blank#}8{#/blank#} a while, she knew that this was a present which was bound to please him.

    When Jane got home, her parents were already at table having supper. Her mother was {#blank#}9{#/blank#}(excite). "Your father has decided to stop smoking," Jane {#blank#}10{#/blank#}(inform).

    Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.

    Trust is a tricky business. On the one hand, it's a necessary condition for many worthwhile things such as child care or friendships. On the other hand, {#blank#}1{#/blank#} (put) your faith in the wrong place often carries a high price.

    Then, why do we trust at all? Well, because it feels good. {#blank#}2{#/blank#} people place their trust in an individual or an institution, their brains release oxytocin, a hormone that produces pleasurable feelings and triggers the herding instruction that leads sheep to flock together for safety and prompts humans {#blank#}3{#/blank#} (connect) with one another.

    Swiss Scientists have found that exposure{#blank#}4{#/blank#} this hormone puts us in a trusting mood: In a study, researchers sprayed oxytocin (催产素) into the noses of half the subjects; those subjects were ready to lend significantly {#blank#}5{#/blank#} (high) amounts of money to strangers than were their counterparts{#blank#}6{#/blank#}inhaled something else.

    Lucky for us, we also have a sixth sense for dishonesty that {#blank#}7{#/blank#} protect us. A Canadian study found that children as young as 14 months can differentiate between a credible person and a dishonest {#blank#}8{#/blank#}. Sixty toddlers were each introduced to an adult tester holding a plastic container. The tester would ask, "What's in here?" before looking into the container, smiling, and exclaiming, "Wow!" Each subject was then invited to look inside. Half of them found a toy; the other half discovered the container was empty-and realized the tester {#blank#}9{#/blank#} (fool) them.

    Among the children who had not been tricked, the majority were willing to cooperate with the tester in learning a new skill, demonstrating that they trusted his leadership. In contrast, only five of the 30 children {#blank#}10{#/blank#} (pair) with the "inflexible" tester participated in a follow-up activity.
